For more than twenty years scientists have been searching for signs of life on other planets. Most of
these searches have been done over the radio. The hope is that someone in outer space may be trying to
get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may answer such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100
light years of the earth. In addition, they will scan the entire sky to "listen" for radio messages from more
distant stars. Using a computer, they will be able to monitor more than eight channels at one time.
Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy(银河星系), scientists find that 5% are like our sun.
Perhaps half of them have a planet like the earth. Such a planet would be a reasonable distance from the
star for temperatures to be right for the evolution(进化) of life. Based on the inhabitable (适于居住的)
planets in our galaxy, most scientists agree that chances are likely that one or more of these planets
support some life.
However, many scientists wonder whether intelligent life exists on other planets. Some believe that
twenty years of searching without any intelligible messages shows that no one is out there. They say that
the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn"t been long enough to rule out the possibility that intelligent
life exists in our galaxy. If we hope to find intelligent life, these scientists believe that we have to keep
looking. |

Without most people realizing it, there has been a revolution in office work over the last ten years.
Before that time, large computers were only used by large, rich companies that could afford the
investment. With the advancement of technology, small computers have come into the market, which
are capable of doing the work that used to be done by much larger and expensive computers, so now
most smaller companies can use them.
The main development in small computers has been in the field of word processors (处理器) , or
WPS as they are often called. 40% of British offices are now estimated to have a word processor and
this percentage is growing fast.
There are many advantages in using a word processor for both secretary and manager. The secretary
is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time
to do other more interesting work for the boss. From a manager"s point of view, secretarial time is being
made better use of and money can be saved by doing daily jobs automatically outside office hours.
But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that
fewer secretaries will be needed. Another worry is the increasing medical problems related to work with
visual display units (显示器). The case of a slow loss of sight among people using word processors
seems to have risen greatly. It is also feared that if a woman works at a VDU for long hours, the unborn
child in her body might be killed. Safety screens to put over a VDU have been invented but few
companies in England bother to buy them.
Whatever the arguments for and against word processors are, they are a key feature of this revolution
in office practice. |
| 1. Ten years ago, smaller companies did not use large computers because ________. |
A. these companies had not enough money to buy such expensive computers
B. these computers could not do the work that small computers can do today
C. these computers did not come into the market
D. these companies did not need to use this new technology |
| 2. According to the writer, the main feature of the revolution in office work over the last ten years is_____. |
A. the saving of time and money
B. the use of computers in small companies
C. the wide use of word processors
D. the decreasing number of secretaries |
| 3. It is implied but not directly stated in the passage that with the use of word processors ________. |
A. some secretaries will lose their jobs
B. daily jobs can be done automatically outside office hours
C. medical problems related to work with a VDU have increased greatly
D. the British companies will make less money |
| 4. Which of the following statements is NOT true? |
A. There are both advantages and disadvantages in using a word processor.
B. The British companies care much for the health of the people using word processors.
C. The technology in the field of computers has been greatly advanced over the last ten years.
D. Using word processors, secretaries can get more time to do more interesting work for their bosses. |
| 5. It can be concluded from the passage that ________. |
A. safety screens are of poor quality
B. working at a VDU for a long time is good for one"s health
C. more and more British offices will use word processors
D. British companies will need fewer and fewer managers |

_1 Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly
similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge (隆起) structure on a person"s fingers does not change with growth and is not affected by
surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by
new one, which bears a reproduction of the original pattern. _2 Some criminals make use of this fact to
remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer"s ink. They can be recorded easily. _3 Because of
the simplicity and economy of this system, finger-prints have often been used as a method of solving
criminal case. A suspected man may deny a charge but this may be in vain. 4 When a suspect leaves
finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.
_5 Some of the marks found are incomplete but identification is possible if a print of a quarter of an
inch square can be obtained.
A. Special techniques are used to "develop" them.
B. A fingerprint is an impression of the friction ridges of all part of the finger.
C. It is only when the inner skin is injured that the arrangement will be destroyed.
D. With special methods, identification can be achieved successfully within a short time.
E. This is called a latent print.
F. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
G. Every human being has a unique arrangement of the skin on his fingers and this arrangement
is unchangeable. |

Parents are often amazed at how fast their child grows and develops. New research has determined
that the ability to quantify may develop much sooner than most parents realize.
Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what
previous studies have shown, infants (婴儿)are able to quantify substances (物质)-like sand or water-as
early as 10 months. As long as the difference between the two substances is large enough, infants will
choose the larger amount, especially when it comes to food.
With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by
presenting them with two cups: one containing a small amount of food, and one containing a larger
amount. Consistently, the babies chose the larger amount.
"Several studies throughout the last 15 years have shown that infants are very good at telling how
many objects they see; however, infants don"t seem to count things like water or sand," vanMarle said.
"What we"re saying is that they can quantify substances; it"s just much harder. The infants can see how
much food goes into each cup and compare that in their memories. They decide which amount is larger,
and they almost always select the larger one."
This information further refutes (驳斥) the long-held idea that babies "know nothing of the world,"
vanMarle said.
"Since psychologists have begun studying infants with sensitive measures, we"ve discovered a lot of
early abilities. I think for parents, it should be exciting to know that there"s somebody in there that has
some fundamental and basic knowledge of the world, and that knowledge is guiding their development,"
vanMarle said.
In the future, vanMarle says this kind of study could be linked to a child"s progress in math-related
skills, although programs marketed to increase those abilities, such as "Baby Einstein," still have mixed
reviews when it comes to academic study. |
| 1. The quantifying ability refers to the ability to ___. |
A. choose between different substances
B. get much knowledge of the world
C. describe the quantity of something
D. obtain math-related skill |
| 2. What is mainly talked about in Paragraph 4? |
A. The process of doing research.
B. The scientific findings.
C. The final choice of infants.
D. The observation of infants" behavior. |
| 3. We can learn from the text that . |
A. some parents don"t care about their kids
B. people used to think the world is known to babies
C. little research has been done on infants
D. some scholars disagree on baby-training programs |
| 4. What"s the best title of the text? |
A. Breakthrough in Baby Studies
B. Amazing Baby-training Ideas
C. Early Human Abilities
D. Unique Quantifying Methods |

conversations and interrupting your sleep, you can call the police. But what is a whale to do?
Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately,
man-made noise from oil and gas drilling, sonar, and ships is also present.
Low frequency noise has doubled off the California coast every decade since the nineteen sixties.
The main reasons are ships" propellers (螺旋桨). They not only generate continuous low frequency
sound, some propellers cavitate (形成气穴), which means they create air bubbles that collapse,
creating loud popping sounds.
Whales use low frequency calls to communicate across thousands of miles of ocean. They are
threatened by noise pollution because it can prevent them from contacting each other and from locating
their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the
water, are the most at risk.
Scientists studying right whales off Canada"s east coast have discovered that whales are sending
louder calls through the water to make themselves heard. Because they invest more energy in making
calls, they have less energy available for finding food and mating. Other scientists measuring whale calls
against background noise pollution have discovered that right whales have lost about eighty percent of
their normal communication area. This could seriously affect survival of this already threatened species.
Scientists don"t have badges and guns, but they are trying to correct the noise pollution problem. By
tracking ships and marine mammals and understanding how noise travels, they are creating sound maps.
They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas
most important to the whales. | | 1. What does the passage mainly talk about? | A. Whales are in danger because of the noise.B. Noise pollution is affecting whales.
C. Natural noise is good for whales.D. How to protect whales endangered. | | 2. The following statements are true EXCEPT ________. | A. You can call the police if you are disturbed by a noise neighbor
B. Low frequency noise has doubled off the Canadian coast every decade since 1960s.
C. Noise pollution can prevent whales from contacting each other and from locating prey.
D. Endangered humpback and right whales are the most at risk. | | 3. We can infer from the last paragraph that ________. | A. Some areas important to whales are overlapped with the ship lanes.
B. Scientists are creating the sound maps by tracking ships and marine mammals.
C. If scientists have guns, they can correct the noise pollution.
D. Scientists have worked out a plan to protect the whales. | | 4. According to scientists, ________. | A. Right whales off the Californian coast have been in danger because of the loss of the energy.
B. Right whales cannot find food and mate for they lose a lot of living area.
C. There are about 20% of the normal communication areas still available for the right whales.
D. The right whales always invest most of their energy for making calls. | | 5. According to the description of whales, we can know that ________. | A. The noise made by the ships has a bad effect on the area where whales live.
B. Whales can communicate with each other by diving into the deep water.
C. Whales cannot find mates because they don"t have enough energy.
D. The communication between whales is through low frequency calls | 最新试题
