Temporal lobes become active too.
But there was also activity
in the temporal lobes at the side of the head consistent with attempts to rouse
stored knowledge and in many other brain areas.
[Cambridge Ielts5_Test 2_Passage 2]
Sensors will be used in the future by
Australians.
With the Cooperative Research
Centre for Micro Technology in Melbourne, they are developing unobtrusive
sensors that will be embedded in an athlete's clothes or running shoes to
monitor heart rate, sweating, heat production or any other factor that might
have an impact on an athlete's ability to run.
A competition model help an athlete plan their
performance in an event.
Well before a championship,
sports scientists and coaches start to prepare the athlete by developing a
'competition model', based on what they expect will be the winning times. [Cambridge Ielts6_Test 1_Passage 1]
Modern cargo-handling methods have had a significant
effect on trade as the business of moving freight around the world becomes
increasingly streamlined.
To see how this influences
trade, consider the business of making disk drives for computers. [Cambridge Ielts6_Test 1_Passage 2]
There was less bullying in
secondary schools, with about one in twenty-five suffering persistent bullying,
but these cases may be particularly recalcitrant. [Cambridge
Ielts6_Test 4_Passage 3-31 ]
Radar and sonar are based on similar
But the underlying
mathematical theories of radar and sonar are very similar and much of our
scientific understanding of the details of what bats are doing has come from applying radar theory to
them. [Cambridge Ielts7_Test 1_Passage 1-12]
Higher incomes need not mean more cars.
here is a widespread belief
that increasing wealth encourages people to live farther out where cars are the
only viable transport. The example of European cities refutes that. They are
often wealthier than their American counterparts but have not generated the
same level of car use. [Cambridge Ielts6_Test
2_Passage 1-3]
In Tarkovsky's opinion, the attraction of the cinema
is that it illustrates the passing of time.
For Tarkovsky, the key to
that magic was the way in which cinema created a dynamic image of the real flow
of events. A still picture could only imply the existence of time, while time
in a novel passed at the whim of the reader. But in cinema, the real objective
flow of time was captured. [Cambridge Ielts6_Test
3_Passage 1-11 ]
The attraction of actors in films.
The 'star' was another
natural consequence of cinema. [Cambridge Ielts6_Test 3_Passage 1-5 ]
Establish targets and give feedback.
The literature on
goal-setting theory suggests that managers should ensure that all employees
have specific goals and receive comments on how well they are doing in those goals.
[Cambridge Ielts6_Test 3_Passage
2-14 ]
Match rewards to individuals.
Since employees have
different needs, what acts as reinforcement for one may not for another.
Managers could use their knowledge of each employee to personalize the rewards
over which they have control. [Cambridge
Ielts6_Test 3_Passage 2-16 ]
The Nicaraguan National Literacy Crusade aimed to
teach large numbers of illiterate men and women to read and write.
By 1985, about 300,000
illiterate adults from all over the country, many of whom had never attended
primary school, had learnt how to read, write and use numbers.[Cambridge Ielts6_Test 4_Passage 2-14 ]
The most important step is for the school authorities
to produce a policy which makes the school's attitude towards bullying quite
clear.
Evidence suggests that a key
step is to develop a policy on bullying, saying clearly what is meant by
bullying, and giving explicit guidelines on what will be done if it occurs,
what record will be kept, who will be informed, what sanctions will be
employed. [Cambridge Ielts6_Test 4_Passage 3-35 ]
The ability actually comes from perceiving echoes
through the ears.
The sensation of facial
vision, it turns out, really goes in through the ears. Blind people, without
even being aware of the fact, are actually using echoes of their own footsteps
and of other sounds, to sense the presence of obstacles. [Cambridge Ielts7_Test 1_Passage 1-7]
However, even before this was understood, the
principle had been applied in the design of instruments which calculated the
depth of the seabed.
Before this was discovered,
engineers had already built instruments to exploit the principle, for example
to measure the depth of the sea under a ship.[Cambridge
Ielts7_Test 1_Passage 1-8]
This was followed by a wartime application in devices
for finding submarines.
After this technique had been
invented, it was only a matter of time before weapons designers adapted it for
the detection of submarines. [Cambridge Ielts7_Test
1_Passage 1-9]
Early military uses of echolocation.
Both sides in the Second
World War relied heavily on these devices, under such codenames as Asdic
(British) and Sonar (American), as well as Radar (Armenian) or RDF (British),
which uses radio echoes rather than sound echoes. [Cambridge
Ielts7_Test 1_Passage 1-5]
Scientists' call for a revision of policy.
At the outset of the new
millennium, however, the way resource planners think about water is beginning
to change. [Cambridge Ielts7_Test 1_Passage 2-17]
Lozanov therefore made
indirect instruction (suggestion) central to his teaching system. In
suggestopedia, as he called his method, consciousness is shifted away from the
curriculum to focus on something peripheral.[Cambridge
Ielts7_Test 1_Passage 3-30]
However, Lozanov admits that a certain amount of
rituals is necessary in order to convince students, even if this is just a
placebo.
Lozanov acknowledges that the
ritual surrounding suggestion in his own system is also a placebo, but
maintains that without such a placebo people are unable or afraid to tap the
reserve capacity of their brains. [Cambridge
Ielts7_Test 1_Passage 3-37-38]
The builders of pagodas knew how to absorb some of the
power produced by severe weather conditions.
Clearly, Japanese carpenters
of the day knew a few tricks about allowing a building to sway and settle
itself rather than fight nature's forces. But what sort of tricks? [Cambridge Ielts7_Test 2_Passage 1-4]
Professor Pretty wants the government to initiate
change by establishing what he refers to as a “Greener Food Standard”.
He is recommending the
immediate introduction of a "Greener Food Standard", which would push
the market towards more sustainable environmental practices than the current
norm, while not requiring the full commitment to organic production. [Cambridge Ielts7_Test 2_Passage 2-25]
The improvement of secondary roads and paths was done
only at the request of local people who were willing to lend a hand.
Paths and secondary roads
were improved only at the request of communities who were willing to
participate in construction and maintenance. [Cambridge
Ielts7_Test 2_Passage 3-38]
Ants can't digest the
cellulose in leaves - but some fungi can. The ants therefore cultivate these
fungi in their nests, bringing them leaves to feed on, and then use them as a
source of food. [Cambridge Ielts7_Test 3_Passage
1-7]
Dental evidence.
There are two other kinds of
research that have thrown some light on the origins of the Native American
population; they involve the study of teeth and of languages. [Cambridge Ielts7_Test 3_Passage 2-19]
The Strasbourg conference decided that a forest policy
must allow for the possibility of change.
A general declaration was
made that a central place in any ecologically coherent forest policy must be
given to continuity over time and to the possible effects of unforeseen events,
to ensure that the full potential of these forests is maintained. [Cambridge Ielts7_Test 3_Passage 3-33]
Earlier this year, the team
put Clemmons's unlikely theory to the test, using a 40-squaremetre rectangular
nylon sail. [Cambridge Ielts7_Test 4_Passage 1-7]
The team decided that it was possible to
use kites to raise very heavy stones.
So Clemmons was right: the
pyramid builders could have used kites to lift massive stones into place.
"Whether they actually did is another matter: Gharib says. [Cambridge Ielts7_Test 4_Passage 1-7]
As a result of the collapse of the salmon runs in
1999, the state decided to close down all fisheries.
The crisis was completely
unexpected, but researchers believe it had nothing to do with impacts of
fisheries. Rather, they contend, it was almost certainly the result of climatic
shifts, prompted in part by cumulative effects of the elnino/lanina phenomenon
on Pacific (ocean temperatures, culminating in a harsh winter in which huge
numbers of salmon eggs were frozen). It
could have meant the end as far as the certification process was concerned.
However, the state reacted quickly, closing down all fisheries, even those
necessary for subsistence purposes. [Cambridge
Ielts7_Test 4_Passage 2-25]
The problems associated with
exposure to noise do not arise if the subject knows they can make it stop.
Predictability is not the
only variable that reduces or eliminates the negative effects of noise. Another
is control. If the individual knows that he or she can control the noise, this
seems to eliminate both its negative effects at the time and its after-effects.
[Cambridge Ielts7_Test 4_Passage 3-37]
Long-term exposure to noise can
produce changes in behavior which can still be observed a year later.
A follow-up study showed that
children who were moved to less noisy classrooms still showed greater
distractibility one year later than students who had always been in the quiet
schools (Cohen et al. 1981).[Cambridge Ielts7_Test
4_Passage 3-36]
In 1764 Dr Johnson accepted the contract to produce a
dictionary. Having rented a garret, he took on a number of copying clerks who
stood at a long central desk.
James Boswell, his
biographer, described the garret where Johnson worked as 'fitted up like a
counting house' with a long desk running down the middle at which the copying
clerks would work standing up. [Cambridge
Ielts5_Test 1_Passage 1-4]
Johnson did not have a available to him, but eventually
produced definitions of in excess of 40.000 words written down in 80 large
notebooks.
The work was immense; filling
about eighty large notebooks (and without a library to hand), John6son wrote
the definitions of over 40.000 words, and illustrated their many meanings with
some 114,000 quotations drawn from English writing on every subject, from the
Elizabethans to his own time. [Cambridge
Ielts5_Test 1_Passage 1-5]
Johnson's Dictionary took into account subtitles of
meaning.
He did not expect to achieve
complete originality. Working to a deadline, he had to draw on the best of all
previous dictionaries, and to make his work one of heroic synthesis. In fact,
it was very much more. Unlike his predecessors, Johnson treated English very
practically; as a living language, with many different shades of meaning. [Cambridge Ielts5_Test 1_Passage 1-3]
The teacher-subjects were told that they were testing
whether punishment helps learning.
Specifically, Milgram told
each volunteer 'teacher-subject' that the experiment was in the noble cause of
education, and was designed to test whether or not punishing pupils for their
mistakes would have a positive effect on the pupils' ability to learn. [Cambridge Ielts5_Test 1_Passage 2-20]
A biological explanation of the
teacher-subjects behavior.
One's first inclination might
be to argue that there must be some sort of built-in animal aggression instinct
that was activated by the experiment, and that Milgram's teacher subjects were
just following a genetic need to discharge this pent-up primal urge onto the
pupil by administering the electrical shock. [Cambridge
Ielts5_Test 1_Passage 2-14]
The general aim of socio-biological
study.
This, in essence, is the
problem of modern sociobiology - to discover the degree to which hard-wired
genetic programming dictates, or at least strongly biases, the interaction at
animals and humans with their environment, that is, their behavior. [Cambridge Ielts5_Test 1_Passage 2-18]
The writer suggests that newspapers print items that
are intended to meet their readers' expectations.
A third source of confusion
is the attitude of the media. People are clearly more curious about bad news
than good. Newspapers and broadcasters are there to provide what the public
wants. [Cambridge Ielts5_Test 1_Passage 3-36]
Kant believed that a successful joke involves the
controlled release of nervous energy.
Kant and Freud felt that
joke-telling relies on building up a psychic tension which is safely punctured
by the ludicrousness of the punch-line. [Cambridge
Ielts5_Test 2_Passage 2-16]
Chimpanzees make particular noise when they are
playing.
Chimpanzees have a
'play-face' - a gaping expression accompanied by a panting 'ah, ah' noise. [Cambridge Ielts5_Test 2_Passage 2-20]
One of the brain's most difficult tasks is to respond
instantly to whatever is happening.
Making a rapid emotional
assessment of the events of the moment is an extremely demanding job for the
brain, animal or human. [Cambridge Ielts5_Test
2_Passage 2-24]
This situation only changed after 1660 when scientists
associated with the set about
developing English.
Fortunately, several members
of the Royal Society possessed an interest in language and became engaged in
various linguistic projects. [Cambridge Ielts5_Test
2_Passage 32]
The 'Missouri' programmer supplied many forms of
support and training to parents
The 'Missouri' programmer
involved trained parent educators visiting the parents' home and working with
the parent, or parents, and the child. [Cambridge
Ielts5_Test 3_Passage 1-8]
Water is pumped from the irrigation canals into the
lagoons.
The sediment sinks to the
bottom of the canals and then is added to fields by farmers or pumped with the
water into the four large freshwater lagoons that are located near the outer
edges of the delta. [Cambridge Ielts5_Test
3_Passage 2-23]
However, it has one disadvantage: it can shatter unexpectedly.
When this happens, the
crystals expand by up to 4%. And if they are within the central, tensile region
of the pane, the stresses this unleashes can shatter the whole sheet. The time
that elapses before failure occurs is unpredictable. It could happen just
months after manufacture, or decades later. [Cambridge
Ielts5_Test 4_Passage 2-19]
The frequency with which such problems occur is by glass experts. Furthermore, the crystals
cannot be detected without sophisticate equipment.
But he insists that cases are
few and far between. 'It’s a very rare phenomenon,' he says.
Others disagree. 'On average
I see about one or two buildings a month suffering from nickel sulphide related
failures,' says Barrie Josie. [Cambridge
Ielts5_Test 4_Passage 2-23]
Tolerance to shade is one criterion for the of plants in forestry and horticulture.
Plants in general can be
divided into two groups: shade-tolerant species and shade-intolerant species.
This classification is commonly used in forestry and horticulture.
Shade-tolerant plants have lower photosynthetic rates and hence have lower
growth rates than those of shade-intolerant species.
[Cambridge Ielts5_Test 4_Passage 3-40]
A reference to the exchange of expertise between
different sports.
AIS scientists work across a
number of sports, applying skills learned in one – such as building muscle
strength in golfers – to others. [Cambridge
Ielts6_Test 1_Passage 1]
Cells focus on
because food is in short supply.
Another hypothesis suggests
that decreased processing of glucose could indicate to cells that food is
scarce (even if it isn't) and induce them to shift into an anti-aging mode that
emphasizes preservation of the organism over such 'luxuries' as growth and
reproduction. [Cambridge Ielts6_Test 3_Passage
3-40]
Children who are bullied may have difficulty forming
relationships in later life.
Victimized pupils are more
likely to experience difficulties with interpersonal relationships as adults,
while children who persistently bully are more likely to grow up to be
physically violent, and convicted of anti-social offences. [Cambridge Ielts6_Test 4_Passage 3-32 ]
Effective work can also be done with individual pupils
and small groups. For example, potential victims of bullying can be trained to
be more self-confident.
There are also ways of
working with individual pupils, or in small groups. Assertiveness training for
pupils who are liable to be victims is worthwhile. [Cambridge
Ielts6_Test 4_Passage 3 -38]
City life is one factor that encourages the
development of intelligence.
Whereas prehistoric man had
no exposure to urban lifestyles - the forcing house of intelligence - the
evidence suggests that ants have lived in urban settings for close on a hundred
million years, developing and maintaining underground cities of specialized
chambers and tunnels. [Cambridge Ielts7_Test
3_Passage 1-2]
Subjects exposed to
noise find it difficult at first to concentrate on problem-solving tasks.
The noise was quite
disruptive at first, but after about four minutes the subjects were doing just
as well on their tasks as control subjects who were not exposed to noise. [Cambridge Ielts7_Test 4_Passage 3-35]
Some types of bird can be encouraged to breed out of
season.
For example, some species of
birds' breeding can be induced even in midwinter simply by increasing day
length artificially. [Cambridge Ielts5_Test
4_Passage 3-28]
Desert annuals respond to as a signal for reproduction.
Day-neutral plants have an
evolutionary advantage when the connection between the favorable period for
reproduction and day length is much less certain. For example, desert annuals
germinate, flower and seed whenever suitable rainfall occurs, regardless of the
day length. [Cambridge Ielts5_Test 4_Passage 3-38]
Plants that flower when days are long often depend on
insects to help them reproduce.
Short-day plants that flower
in spring in the temperate zone are adapted to maximizing seedling growth
during the growing season. Long-day plants are adapted for situations that
require fertilization by insects or a long period of seed ripening. [Cambridge Ielts5_Test 4_Passage 3-37]
Reasons why an education programmer failed
Despite substantial funding,
results have been disappointing. It is thought that there are two explanations
for this. [Cambridge Ielts5_Test 3_Passage 1-3]
All kinds of species of trees should be preserved.
The second resolution
concentrates on the need to preserve the genetic diversity of European forests. [Cambridge Ielts7_Test 3_Passage 3-35]
Resources should be allocated to research into tree
diseases.
The fifth resolution are
launched the European research network on the physiology of trees, called Euro
Silva. Euro Silva should support joint European research on tree diseases and
their physiological and biochemical aspects.
[Cambridge Ielts7_Test 3_Passage 3-38]
Research is to be better coordinated throughout
Europe.
Finally, the conference
established the framework for a European research network on forest ecosystems.
This would also involve harmonizing activities in individual countries as well
as identifying a number of priority research topics relating to the protection
of forests. [Cambridge Ielts7_Test 3_Passage 3-39]
It is generally believed that large numbers of people
were needed to build the pyramids.
The conventional picture is
that tens of thousands of slaves dragged stones on sledges. [Cambridge Ielts7_Test 4_Passage 1-1]
More than 320,000 tonnes of salmon were
caught in Alaska in 2000.
During 2000, commercial
catches of Pacific salmon in Alaska exceeded 320,000 tonnes, with an ex-vessel
value of over $US260 million. [Cambridge
Ielts7_Test 4_Passage 2-18]
Biologists have the authority to stop people fishing
for sport.
The fishermen know the
approximate time of year when they will be allowed to fish, but on any given
day, one or more field biologists in a particular area can put a halt to
fishing. Even sport fishing can be brought to a halt. [Cambridge
Ielts7_Test 4_Passage 2-22]
In September 2000, the MSC allowed seven Alaska salmon
companies to label their products using the MSC logo.
In September 2000, MSC
announced that the Alaska salmon fisheries qualified for certification. Seven
companies producing Alaska salmon were immediately granted permission to
display the MSC logo on their products; [Cambridge
Ielts7_Test 4_Passage 2-26]
An explanation for reduced water use.
(G) What explains this
remarkable turn of events? Two factors: people have figured out how to use
water more efficiently, and communities are rethinking their priorities for
water use. [Cambridge Ielts7_Test 1_Passage 2-19]
One effect of chemicals on water sources.
Natural soil fertility is
dropping in many areas because of continuous industrial fertilizer and pesticide
use, while the growth of algae is increasing in lakes because of the fertilizer
run-off. [Cambridge Ielts7_Test 2_Passage 2-17]
Noise affects a
subject's capacity to repeat numbers while carrying out another task.
Similarly, noise did not
affect a subject's ability to track a moving line with a steering wheel, but it
did interfere with the subject's ability to repeat numbers while tracking

4_Passage 3-40]
The explanation Milgram gave the
teacher-subjects for the experiment.
Specifically, Milgram told
each volunteer 'teacher-subject' that the experiment was in the noble cause of education,

would have a positive effect on the pupils' ability to learn. [Cambridge Ielts5_Test 1_Passage 2-15]
Applications of AI have already had a degree of
success.
But the tide may now be
turning, according to Dr Leake, HNC Software of San Diego, backed by a
government agency, reckon that their new approach to artificial intelligence is
the most powerful and promising approach ever discover.
[Cambridge Ielts5_Test 3_Passage 3-35]
Research shows that promotion works.
Free samples of new and
expensive drugs might be the single most effective way of getting doctors and
patients to become loyal to a product. [Cambridge Ielts6_Test 4_Passage 1-6 ]
The writer express concern about the selection of
areas to research.
One is the lopsidedness built
into scientific research. Scientific funding goes mainly to areas with many
problems. That may be wise policy, but it will also create an impression that
many more potential problems exist than is the case.
[Cambridge Ielts5_Test 1_Passage 3-33]
Information is to be systematically gathered on any
decline in the condition of forests.
That general declaration was
accompanied by six detailed resolutions to assist national policymaking. The
first proposes the extension and systematization of surveillance sites to
monitor forest decline. [Cambridge Ielts7_Test
3_Passage 3-34]
Besides the laboratory
evidence for this, we know from our experience that we often remember what we
have perceived peripherally, long after we have forgotten what we set out to
learn. [Cambridge Ielts7_Test 1_Passage 3-28]
Subjects find it difficult to
perform three tasks at the same time when exposed to noise.
For example, high noise
levels interfered with the performance of subjects who were required to monitor
three dials at a time, a task not unlike that of an aero plane pilot or an air
traffic controller (Broadbent. 1957). [Cambridge
Ielts7_Test 4_Passage 3-39]
The word "echolocation" was first used by
someone working as a .
The American zoologist Donald
Grimwho was largely responsible for the discovery of sonar in bats, coined the
term echolocation to cover both sonar and radar, whether used by animals

A successful exercise in people power.
'The more democratic the process, the more
public transport is favored.' He considers Portland, Oregon, a perfect example

In seventh-century Europe, the ability to count to a
certain number was necessary in order to fulfill a civic role.
The average person in the
seventh century in Europe was not as familiar with numbers as we are today. In
fact, to qualify as a witness in a court of law a man had to be able to count
to nine! [Cambridge Ielts6_Test 2_Passage 3-29 ]

The similar cost involved in transporting a product
from abroad or from a local supplier.
Computer manufacturers in
Japan or Texas will not face hugely bigger freight bills if they import drives
from Singapore rather than purchasing them on the domestic market. [Cambridge Ielts6_Test 1_Passage 2-16]
Regular amounts of exercise may help prevent mental
decline.
Maintaining a level of daily
physical activity may help mental functioning, says Carl Cotman, a
neuroscientist at the University of California at Irvine. [Cambridge Ielts6_Test 2_Passage 2-24]
Some peoples with simple number systems use body
language to prevent
misunderstanding of expressions of number.
But in real situations the
number and words are often accompanied by gestures to help resolve any
confusion. [Cambridge Ielts6_Test 2_Passage 3-34 ]
Not many people are likely to find a
caloric-restricted diet attractive.
Few mortals could stick to
chat harsh a regimen, especially for years on end. [Cambridge
Ielts6_Test 3_Passage 3-30]
Control monkeys produced greater quantities of
insulin.
The monkey projects
demonstrate that, compared with control animals that eat normally,
caloric-restricted monkeys have lower body temperatures and levels of the
pancreatic hormone insulin, and they retain more youthful levels of certain
hormones that tend to fall with age. [Cambridge
Ielts6_Test 3_Passage 3-37]
Control monkeys experienced more chronic disease.
Further, it has recently been
shown that rhesus monkeys kept on caloric-restricted diets for an extended
time(nearly 15 years) have less chronic disease. [Cambridge
Ielts6_Test 3_Passage 3-34]
Evidence of drug promotion is clearly visible in the
healthcare environment.
Rarely do patient nurse use a

Ielts6_Test 4_Passage 1-11 ]
How early mammals avoided dying out.
In the time when the
dinosaurs dominated the daytime economy, our mammalian ancestors probably only
managed to survive at all because they found ways of scraping a living at

A surprising downward trend in demand for water.
Fortunately - and
unexpectedly - the demand for water is not rising as rapidly as some predicted.

In the follow-up class, the teaching activities are
similar to those used in conventional classes.
Some hours after the two-part
session, there is a follow-up class at which the students are stimulated to

teaching. [Cambridge Ielts7_Test 1_Passage 3-33]
Floors fitting loosely over each other.
More surprising is the fact
that the individual storey of a Japanese pagoda, unlike their counterparts

2_Passage 3-39]
In noise experiments, Glass and Singer found that
bursts of noise do not seriously disrupt problem-solving in the long term.
For example, Glass and Singer
(1972) exposed people to short bursts of very loud noise and then measured
their ability to work out problems and their physiological reactions to the
noise. The noise was quite disruptive at first, but after about four minutes
the subjects were doing just as well on their tasks as control subjects who
were not exposed to noise. [Cambridge Ielts7_Test
4_Passage 3-28]
Researchers discovered that high noise levels are not
likely to interfere with the successful performance of a single task.
But there are limits to
adaptation and loud noise becomes more troublesome if the person is required to
concentrate on more than one task. [Cambridge
Ielts7_Test 4_Passage 3-29]
Not all of the assistants survived to see the publication

Little doubt was expressed about the reason for the
Bishops Walk accident.
On 2nd August 1999, a
particularly hot day in tile town of Cirencester in the UK, a large pane of
toughened glass in the roof of a shopping centre at Bishops Walk shattered
without warning and fell from its frame. When fragments were analyzed by
experts at the giant glass manufacturer Pilkington, which had made the pane,
they found that minute crystals of nickel sulphide trapped inside the glass had
almost certainly caused the failure. [Cambridge

Scientists have yet to determine the cue for Chusquea
abietifolia's seasonal rhythm.
Every bamboo of the species
Chusquea abietifalia on the island of Jamaica flowered, set seed and died
during 1884. The next generation of bamboo flowered and died between 1916 and
1918, which suggests a vegetative cycle of about 31 years. The climatic trigger
for this flowering cycle is not yet known, but the adaptive significance is
clear. [Cambridge Ielts5_Test 4_Passage 3-32]
In experiments, rats who ate what they wanted led
shorter lives than rats on a low calorie.
Scientists first recognized
the value of the practice more than 60 years ago, when they found that rats fed
a low-calorie diet lived longer on average than free-feeding rats and also had
a reduced incidence of conditions that become increasingly common in old age. [Cambridge Ielts6_Test 3_Passage 3-32]
When cinema first began, people thought that its
future was uncertain.
Cinema has also given a new
lease of life to the idea of the story. When the Lumiere Brothers and other
pioneers began showing off this new invention, it was by no means obvious how
it would be used. [Cambridge Ielts6_Test 3_Passage
1-12 ]
An explanation of how visual imaging is employed in
investigations.
It collects images from
digital cameras running at 50 frames a second and breaks down each part of a
swimmer's performance into factors that can be analyzed individually. [Cambridge Ielts6_Test 1_Passage 1]
The effects of the introduction of electronic
delivery.
Computer software can be
'exported' without ever loading it onto a ship, simply by transmitting it over
telephone lines from one country to another. [Cambridge
Ielts6_Test 1_Passage 2-15]
Imported produce is particularly expensive.
It would cost a family around
£7,000 a year to replace meat they obtained themselves through hunting with
imported meat. [Cambridge Ielts6_Test 1_Passage
3-40]
A developed system of numbering was necessary when
people began farming.
As they began to settle, grow
plants and herd animals, the need for a sophisticated number system became
paramount. [Cambridge Ielts6_Test 2_Passage 3-27 ]
It is important to understand how the first audiences
reacted to the cinema.
But it is worth trying, for
to understand the initial shock of those images is to understand the
extraordinary power and magic of cinema, the unique, hypnotic quality that has
made film the most dynamic, effective art form of the 20th century. [Cambridge Ielts6_Test 3_Passage 1-6 ]
How cinema teaches us about other cultures.
For cinema makes the world
smaller. Long before people traveled to America or anywhere else, they knew
what other places looked like; they know how other people worked and lived. [Cambridge Ielts6_Test 3_Passage 1-4]
Gifts include financial incentives
But on any given day what
Schaefer can offer is typical for today's drugs rep - a car trunk full of
promotional gifts and gadgets, a budget that could buy lunches and dinners for
a small county, hundreds of free drug samples and the freedom to give a
physician $200 to prescribe her new product to the next six patients who fit
the drug's profile. [Cambridge Ielts6_Test
4_Passage 1-2]
Interrupting a natural process
Up to now, people have blamed
this loss of delta land on the two large dams at Aswan in the south of Egypt,
which hold back virtually all of the sediment that used to flow down the river.
[Cambridge Ielts5_Test 3_Passage 2-14]
How Al could help deal with difficulties related to
the amount of information available electronically
In particular, the problem of
information overload, exacerbated by the growth of e-mail and the explosion in
the number of web pages, means there are plenty of opportunities for new
technologies to help filter and categories information - classic AI problems. [Cambridge Ielts5_Test 3_Passage 3-30]
The reaction of the Inuit community to climate change.
In Canada, where the Inuit
people are jealously guarding their hard-won autonomy in the country's newest
territory, Nunavut, they believe their best hope of survival in this changing
environment lies in combining their ancestral knowledge with the best of modern
science. This is a challenge in itself. [Cambridge Ielts6_Test 1_Passage 3-27]
The location of the first cinema.
The Lumiere Brothers opened
their Cinematographe, at 14 Boulevard des Capucines in Paris, to 100 paying
customers over 100 years ago, on December 8, 1895. [Cambridge
Ielts6_Test 3_Passage 1-1 ]
The writer refers to the film of the train in order to
demonstrate the impact of early films.
As the train approached,'

Who really pays for doctors' free gifts?
And patients are the ones who
pay-in the form of sky-rocketing prescription prices-for every pen that's

The reaction from schools to enquiries about bullying.
Perhaps as a consequence,
schools would often deny the problem.
[Cambridge
Ielts6_Test 4_Passage 3-29 ]
It should include detailed 36 as to how the
school and its staff will react if bullying occurs.
Evidence suggests that a key
step is to develop a policy on bullying, saying clearly what is meant by
bullying, and giving explicit guidelines on what will be done if it occurs,
what record will be kept, who will be informed, what sanctions will be
employed. [Cambridge Ielts6_Test 4_Passage 3-36]
A description of ancient water supplies.
At the height of the Roman
Empire, nine major systems, with an innovative layout of pipes and well-built
sewers, supplied the occupants of Rome with as much water per person as is provided
in many parts of the industrial world today.
[Cambridge Ielts7_Test 1_Passage 2-14]
Environmental effects.
More than 20 % of all
freshwater fish species are now threatened or endangered because dams and water
withdrawals have destroyed the free-flowing river ecosystems where they thrive.
Certain irrigation practices degrade soil quality and reduce agricultural
productivity. [Cambridge Ielts7_Test 1_Passage
2-16]
Identifying the main transport problems.
When the project began,
Makete District was virtually totally isolated during the rainy season. The
regional road was in such bad shape that access to the main towns was
impossible for about three months of the year. Road traffic was extremely rare
within the district, and alternative means of transport were restricted to
donkeys in the north of the district. [Cambridge
Ielts7_Test 2_Passage 3-27]
The teacher-subject was told
that whenever the pupil gives the wrong answer to a question, a shock was to be
administered, beginning at the lowest level and increasing in severity with
each successive wrong answer. [Cambridge
Ielts5_Test 1_Passage 2-21]
The identity of the pupils.
The supposed 'pupil' was in
reality an actor hired by Milgram to simulate receiving the shocks by emitting
a spectrum of groans, screams and writings together with an assortment of
statements and expletives denouncing both the experiment and the experimenter. [Cambridge Ielts5_Test 1_Passage 2-16]
The overwhelming consensus
was that virtually all the teacher-subjects would refuse to obey the
experimenter. The psychiatrists felt that 'most subjects would not go beyond
150 volts' and they further anticipated that only four percent would go up to
300 volts. Furthermore, they thought that only a lunatic fringe of about one in
1.000 would give the highest shock of 450 volts.
What were the actual results?
Well, over 60 per cent of the teacher-subjects continued to obey Milgram up to
the 450-volt limit. [Cambridge Ielts5_Test
1_Passage 2-22]
Peter Derks believes that humor may provide valuable
information about the operation of the brain.
As Peter Derks, a
psychologist at William and Mary College In Virginia says: "I like to
think of humor as the distorted mirror of the mind. It's creative, perceptual,
analytical and lingual. If we can figure out how the mind processes humor, then
we'll have a pretty good handle on how it works in general. [Cambridge Ielts5_Test 2_Passage 2-27]
Effects of irrigation on sedimentation.
The water in the irrigation
canals is still or very slow-moving and thus cannot carry sediment, Stanley
explains. The sediment sinks to the bottom of the canals and then is added to
fields by farmers or pumped with the water into the four large freshwater
lagoons that are located near the outer edges of the delta. [Cambridge Ielts5_Test 3_Passage 2-15]
Looking at the long-term impact.
According to Siegel,
international environmental organizations are beginning to pay closer attention
to the region, partly because of the problems of erosion and pollution of the
Nile delta, but principally because they fear the impact this situation could
have on the whole Mediterranean coastal ecosystem.
[Cambridge Ielts5_Test 3_Passage 2-17]
How obstacles to optimum achievement can be
investigated.
With the Cooperative Research
Centre for Micro Technology in Melbourne, they are developing unobtrusive
sensors that will be embedded in an athlete's clothes or running shoes to
monitor heart rate, sweating, heat production or any other factor that might
have an impact on an athlete's ability to run.
[Cambridge Ielts6_Test 1_Passage 1]
The fact that Al brings together a range of separate
research areas.
The expression provided an
attractive but informative name for a research programmer that encompassed such
previously disparate fields as operations research, cybernetics logic and computer
science. The goal they shared was an attempt to capture or mimic human
abilities using machines. [Cambridge Ielts5_Test
3_Passage 3]
Research into how common bullying is in British
schools.
A survey conducted with Irene
Whitney found that in British primary schools up to a quarter of pupils
reported experience of bullying, which in about one in ten cases was
persistent. There was less bullying in secondary schools, with about one in
twenty-five suffering persistent bullying, but these cases may be particularly
recalcitrant. [Cambridge Ielts6_Test 4_Passage 3-27
]
The effect of bullying on the children involved.
Victimized pupils are more
likely to experience difficulties with interpersonal
relationships as adults,
while children who persistently bully are more likely to grow up to be
physically violent, and convicted of anti-social offences. [Cambridge Ielts6_Test 4_Passage 3-28 ]
Why bats hunt in the dark.
Given that there is a living
to be made at night, and given that alternative daytime trades are thoroughly
occupied, natural selection has favored bats that make a go of the
night-hunting trade. [Cambridge Ielts7_Test
1_Passage 1-3]
The relevance to health.
As the United Nations report
on access to water reiterated in November 2001, more than one billion people
lack access to clean drinking water; some two and a half billion do not have
adequate sanitation services. Preventable water-related diseases kill an
estimated 10,000 to 20,000 children every day, and the latest evidence suggests
that we are falling behind in efforts to solve these problems. [Cambridge Ielts7_Test 1_Passage 2-15]
The stages in the development of the farming industry.
First mechanization, then
mass use of chemical fertilizers and pesticides, then monocultures, then
battery rearing of livestock, and now genetic engineering - the onward march of
intensive farming has seemed unstoppable in the last half-century, as the
yields of produce have soared. [Cambridge
Ielts7_Test 2_Passage 2-15]
Several species of wildlife in the British countryside
are declining.
In Britain, for example, many
of our best-loved farmland birds, such as the skylark, the grey partridge, the
lapwing and the corn bunting, have vanished from huge stretches of countryside,
as have even more wild flowers and insects.
[Cambridge Ielts7_Test 2_Passage 2-18]
The way Milgram persuaded the
teacher-subjects to continue".
In these situations, Milgram
calmly explained that the teacher-subject was to ignore the pupil's cries for
mercy and carry on with the experiment. If the subject was still reluctant to
proceed, Milgram said that it was important for the sake of the experiment that

Details of the range of family types involved in an
education programmer.
The four-year pilot study
included 380 families who were about to have their first child and who

They included single-parent and two-parent families, families in which both
parents worked, and families with either the mother or father at home. [Cambridge Ielts5_Test 3_Passage 1-1]
Administered to a variety of poor and wealthy families.
The four-year pilot study

However, it has not previously been known whether
these two factors were directly linked or not. This question has been
investigated by an international research team in Nicaragua.
During this period,
researchers from the Liverpool School of Tropical Medicine, the Central
American Institute of Health in Nicaragua, the National Autonomous University
of Nicaragua and the Costa Rican institute of Health interviewed nearly 3,000
women, some of whom had learnt to read as children, some during the literacy
crusade and some who had never learnt at all. [Cambridge

Trevor Ford suggests that publicity about nickel
sulphide failure has been suppressed.
'What you hear is only the
tip of the iceberg: says Trevor Ford, a glass expert at Resolve Engineering in
Brisbane, Queensland. He believes the reason is simple: 'No-one wants bad

The research establishes a link between levels of
education and life expectancy.
One interesting correlation
Manton uncovered is that better-educated people are likely to live longer. [Cambridge Ielts6_Test 2_Passage 2-20]
Examples of wildlife other than bats which do not rely
on vision to navigate by.
Bats are not the only
creatures to face this difficulty today. Obviously the night-flying insects
that they prey on must find their way about somehow. Deep-sea fish and whales
have little or no light by day or by night. Fish and dolphins that live in
extremely muddy water cannot see because, although there is light. It is
obstructed and scattered by the dirt in the water. Plenty of other modern
animals make their living in conditions where seeing is difficult or
impossible. [Cambridge Ielts7_Test 1_Passage 1-1]
Sometimes the desire to protect ideas seems to have
been stronger than the desire to communicate them, particularly in the case of
mathematicians and doctors.
And in the mid-17th century
it was common practice for mathematicians to keep their discoveries and proofs
secret, by writing them in cipher, in obscure languages, or in private messages
deposited in a sealed box with the Royal Society. Some scientists might have
felt more comfortable with Latin precisely because its audience, though
international, was socially restricted. Doctors clung the most keenly to Latin
as an 'insider language'.
[Cambridge
Ielts5_Test 2_Passage 3-29]
In Britain, moreover scientists worried that English
had neither the 30 nor the 31 to express their ideas.
First, it lacked the
necessary technical vocabulary. Second, it lacked the grammatical resources
required to represent the world in an objective and impersonal way, and to
discuss the relations, such as cause and effect, that might hold between
complex and hypothetical entities. [Cambridge
Ielts5_Test 2_Passage 3-30-31]
To deal with this, Stanley suggests the use of in the short term, and increasing the
amount of water available through in
the longer term.
But there are no easy
solutions. In the immediate future, Stanley believes that one solution would be
to make artificial floods to rush out the delta waterways, in the same way that
natural floods did before the construction of the dams. He says, however, that
in the long term an alternative process such as desalination may have to be
used to increase the amount of water available.
[Cambridge Ielts5_Test 3_Passage 2-25-26]
Deserts, mountains and Arctic regions are examples of
environments that are both ecologically and culturally fragile.
These regions are fragile
(i.e. highly vulnerable to abnormal pressures) not just in terms of their
ecology, but also in terms of the culture of their inhabitants. The three most
significant types of fragile environment in these respects, and also in terms
of the proportion of the Earth’s surface they cover, are deserts, mountains and
Arctic areas. [Cambridge Ielts5_Test 4_Passage 1-5]
An additional hand signal was used when the range of
number words was restricted.
For example, when using the one, two, many type of system, the word

The speed with which cinema has changed.
And it has all happened so
quickly. Almost unbelievably, it is a mere 100 years since that train arrived

In 17th-century Britain, leading thinkers combined
their interest in science with an interest in how to express ideas.
Although a proposal in 1664
to establish a committee for improving the English language came to little, the
society's members did a great deal to foster the publication of science in
English and to encourage the development of a suitable writing style. [Cambridge Ielts5_Test 2_Passage 3-37]
Reasons why a child’s early years are so important.
A 13-year study of early
childhood development at Harvard University has shown that, by the age of
three, most children have the potential to understand about 1000 words – most
of the language they will use in ordinary conversation for the rest of their
lives. [Cambridge Ielts5_Test 3_Passage 1-2]
Swiss pays d'Enhaut, revived production of 10.
Local concern about the

The outer layer before the inner layer, and the tension
between the two layers which is created because of this makes the glass

This fault is a result of the manufactured process.
Ordinary glass is first heated, then cooled very .
It is made by heating a sheet
of ordinary glass to about 620 °C to soften it slightly, allowing its structure
to expand, and then cooling it rapidly with jets of cold air. [Cambridge Ielts5_Test 4_Passage 2-20]
Toughened glass is favored by architects because it is
much stronger than ordinary glass, and the fragments are not as when it breaks.
Toughened glass is found
everywhere, from cars and bus shelters to the windows, walls and roofs of
thousands of buildings around the world. It’s easy to see why. This glass has
five times the strength of standard glass, and when it does break it shatters
into tiny cubes rather than large, razor-sharp shards. [Cambridge

[Cambridge Ielts5_Test 1_Passage 1-6]
There were several reasons for the research into
plastics in the nineteenth century, among them the great advances that had been
made in the field of and the
search for alternatives to natural resources like ivory.
The history of today's
plastics begins with the discovery of a series of semi-synthetic thermoplastic
materials in the mid-nineteenth century. The impetus behind the development of
these early plastics was generated by a number of factors - immense
technological progress in the domain of chemistry, coupled with wider cultural
changes, and the pragmatic need to find acceptable substitutes for dwindling
supplies of 'luxury' materials such as tortoise shell and ivory. [Cambridge Ielts5_Test 2_Passage 1-3]
Playground supervision will be more effective if

In Alaska, biologists keep a check on
adult fish to ensure that fish numbers are sufficient to permit fishing.
In-Season A Abundance-Based Management has allowed the
Alaska salmon fisheries to be successful.
The primary reason for such
increases is what is known as ' In-Season Abundance-Based Management."
There are biologists throughout the state constantly monitoring the adult’s
fish as they show up to spawn. It is this management mechanism that has allowed
Alaska salmon stocks - and, accordingly, Alaska salmon fisheries - to prosper,
even as salmon populations in the rest of the United State's are increasingly
considered threatened or even endangered.
[Cambridge Ielts7_Test 4_Passage 2-22-23]
Some people may believe that the teacher-subjects'

Caloric-restricted monkeys enjoyed a reduced chance of
heart disease.
Caloric-restricted monkeys were less likely to become

example, they have lower blood pressure and triglyceride levels (signifying a
decreased likelihood of heart disease),and they have more normal blood glucose
levels(pointing to a reduced risk for diabetes, which is marked by unusually
high blood glucose levels). [Cambridge Ielts6_Test

It would clearly be impossible for the people to
engage in farming as a means of supporting themselves.
Farming is out of the
question and nature offers meager pickings.
[Cambridge Ielts6_Test 1_Passage 3-33]
It also shows that there has been a considerable
reduction in the number of elderly people who are disabled, which means that
the cost involved in supporting this section of the population may be less than
previously predicted.
That represents a significant
drop in the number of disabled old people in the population. If the trends
apparent in the United States 14 years ago had continued, researchers calculate
there would be an additional one million disabled elderly people in today's
population. According to Manton, slowing the trend has saved the United States
government's Medicare system more than $200 billion, suggesting that the
graying of America's population may prove less of a financial burden than
expected. [Cambridge Ielts6_Test 2_Passage 2-22 ]
Some employees can feel manipulated when asked to

High achievers have less
need of external goals.
For those with high

Kim Schaefer's marketing technique may be open to
criticism on moral grounds.
They work in an industry
highly criticized for its sales and marketing practices, but find themselves in

Between 1940 and 1959, there was a sharp decrease in
Alaska's salmon population.
Catches have not always been
so healthy. Between 1940 and 1959, over fishing led to crashes in salmon
populations so severe that in 1953 Alaska was declared a federal disaster area.[Cambridge Ielts7_Test 4_Passage 2-19]
Environmentalists take a pessimistic view of the world
for a number of reasons.
For many environmentalists,
the world seems to be getting worse. They have developed a hit-list of our main
fears: [Cambridge Ielts5_Test 1_Passage 3]
75. The writer quotes from the World Wide Fund for
Nature to illustrate how environmental groups can exaggerate their claims.
Secondly, environmental
groups need to be noticed by the mass media. They also need to keep the money
rolling in. Understandably, perhaps, they sometimes overstate their arguments. [Cambridge Ielts5_Test 1_Passage 3-34]
A reason for narrowing the scope of research activity.
They all focus on one aim:

The writer thinks that the declaration 'There is no
bullying at this school” reflected a lack of knowledge and resources.
Until recently, not much was
known about the topic, and little help was available to teachers to deal with
bullying. Perhaps as a consequence, schools would often deny the problem.
'There is no bullying at this school' has been a common refrain, almost
certainty untrue. [Cambridge Ielts6_Test 4_Passage

Prior to the start of MIRTP the Makete district was
almost inaccessible during the rainy season.
When the project began,
Makete District was virtually totally isolated during the rainy season. [Cambridge Ielts7_Test 2_Passage 3-32]
Frequent breakdown of buses and trucks in Makete
hindered attempts to make the existing transport services more efficient.
The efforts to improve the
efficiency of the existing transport services were not very successful because
most of the motorized vehicles in the district broke down and there were no
resources to repair them. [Cambridge Ielts7_Test

The multi- storey pagoda came
to Japan from China in the sixth century. As in China, they were first
introduced with Buddhism and were attached to important temples. The Chinese
built their pagodas in brick or stone, with inner staircases, and used them in
later centuries mainly as watchtowers. When the pagoda reached Japan, however,
its architecture was freely adapted to local conditions. [Cambridge Ielts7_Test 2_Passage 1-5-7-9]
ShuzoIshida performs experiments in order to learns

Between 1983 and 1990 the numbers of patients visiting
alternative therapists rose to include a further 0.8%of the population
In a 1983 national health
survey, 1.9%of people said they had contacted a chiropractor,
naturopath, osteopath, acupuncturist or herbalist in the two weeks prior to the
