Directions: There are four reading passages in this part. Each passage is followed by some questions. For each question there are four suggested answers marked A, B, C and D. You should choose the one best answer and blacken the corresponding letter on the ANSWER SHEET with a pencil.
Passage 1

How do you send a message to a submerged submarine, particularly one carrying mi Water may not look like a barrier to communications, but appearances are deceiving. Water strongly absorbs all electromagnetic waves except blue green light and extremely low frequency radio waves. The very low frequency waves now used to contract submarines penetrates1 only a short distance into the ocean, so the craft must either surface or send up and antenna2 (天线) to receive messages, thereby3 increasing its weakness. A laser system --- accurate over long distances and capable of carrying more data than the very low frequency waves --- would talk to submarine at their normal depths.

In the system, a very broad beam spreading out freely in all directions would be scanned (扫描) over thousands of square miles of ocean so that it wouldn't endanger boats, birds or fish——or the submarines it is supposed to reach.

Since only a small fraction of the laser system will make its way through the air and ocean, receivers mounted on the submarines must be able not only to detect the laser but also to discriminate4 between it and sunlight. So, military scientists are now working hard on special filter that allow through only the precise wavelengths5 emitted by the laser. The filtered light, when transformed into electrical signal, can then be decoded6. Military planners are confident that laser communication with submarines is feasible.

1. Which of the following does the passage mainly discuss?

A. Missiles carried by submerged submarines.
B. Messages sent by submerged submarines.

A. It is able to make its way through water.
B. It is able to communicate with submarines at work.

4. The reference word “it” (Sentence 1, para.3) refers to .

A. the air
B. the laser beam
C. the ocean
D. the submarine

5. Who would be very much interested in the passage?

A. Missile builders
B. Military scientists

Passage 2

The West begun to take more notice of the East. The fifth volume of an enormous work re-assessing the Chinese contribution to science and technology is to be published next year. The first volume, which was published twenty years ago, set the tone for the whole work. In it, evidence was given to show that many inventions which, until then, western historians had claimed for Europe, were made first in China. The attempt to rewrite the intellectual history of the world was not received without protest by some reputable historians. However, the evidence that has been presented so far in the first four volumes has persuaded many historians who were skeptical7 at first. China's invention of paper, printing, the magnetic compass and gunpowder8 has never been disputed, but this new history has added advanced bridge design, mechanical clocks, paddle boats and many other inventions to the list.

In the four volumes published so far no attempt has been made to explain why China has not kept up with the West in science and technology in modern times. It is probable that the answer is to be found in the social and economic history of China, where a static society under a relatively9 benevolent10 regime of scholar-gentry contrasts with the potentially revolutionary and dynamic society of the West at the end of the Middle Ages. In recent years, the Chinese government has been making every effort to catch up with the West again, and there is little doubt that the gap is being reduced year by year. But will China avoid the West's mistakes?

6. So far, how many volumes have been published?

A. Five.
B. Four.
C. Three.
D. None.

7. The first volume was published .

A. ten years ago
B. last year
C. five years ago
D. twenty years ago

8. In Line 7, the word “skeptical" means .

A. doubtful
B. worried
C. sad
D. angry

9. Which of the following is not mentioned in the passage?

A. Gunpowder.
B. Needle.
C. Paddle boats.
D. Bridge design.

10. The best title for this passage is .

A. China's Inventions
B. Comparisons Between the East and the West
C. China Is Catching11 Up
D. Situations in China

Passage 3

Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dustbin would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.

The new concept of recycling waste is taking shape at the British technological12 laboratory at Warren Spring, not far from the north of London. Today, the laboratory spends four times as much money in studying recycling as it did five years ago.

The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper13, but also paper and rubber as well. Methods have been discovered, for example, for removing the ink from newsprint so that the paper can be used again, and for obtaining valuable oils and gases from old motor car types. All these ideas are already being made use of, but what is new is the idea of combining them on such a large scale in a single plant designed to recycle most types of waste.

Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first, it will pass through sharp metal spikes14 which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that crushers and rollers will break up everything that can be broken finally, and the rubbish will pass under magnets, which will remove the bits of iron and steel; finely the rubber and plastic will then be sorted out in the final stage.

The first full-scale giant recycling plants are, perhaps, fifteen years away. But in some big industrial areas, where rubbish has been dumped for so long that there are no holes left to fill up with rubbish, these new automatic recycling plants may be built sooner. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.

11. Projects for recycling waste in Britain .

A. will not be started for at least fifteen years
B. are being developed all over Britain
C. have not yet been fully15 tested
D. have been abandoned because they are too expensive

12. The purpose of the latest recycling project is

A. to prevent people from putting rubbish into holes
B. to find a way of destroying all kinds of waste
C. to extract useful raw materials from the waste
D. to find out how much raw materials should be provided of people want to recycle the waste

13. The new type of recycling plant will .

A. recycle only paper and rubber
B. not recycle metals, paper or rubber
C. recycle paper, rubber and metals
D. not recycle steel, lead or copper

14. The first recycling plants .

A. have already been built in large industrial areas
B. will not be built for at least fifteen years
C. will probably be built in the next fifteen years
D. will be too expensive to build near big cities.

15. “Well on with" in the first paragraph probably means .

A. finished with
B. nearing completion
C. getting ready to start
D. making improvements on

Passage 4

People with disabilities comprise a large part of the population. It is estimated that over 35 million Americans have physical, mental, or other disabilities. About half of these disabilities are “developmental", i.e., they occur prior to the individual's twenty-second birthday, often from genetic16 conditions, and are severe enough to affect three or more areas of development, such as mobility17, communication, employment, etc. Most other disabilities are considered “adventitious", i.e., accidental or caused by outside forces.

Prior to the 20th century, only a small percentage of people with disabilities survived for long. Medical treatment for these disabilities was unavailable. Advancements18 in medicine and social services have created a climate in which people with disabilities can expect to have such basic needs as food, shelter, and medical treatment. Unfortunately, these basics are often not available. Civil liberties such as the right to vote, marry, get an education, and gain employment have historically been denied on the basis of disability.

In recent decades, the disability rights movement has been organized to fight against these infringements19 of civil rights. Congress responded by passing major legislation recognizing people with disabilities as a protected class under civil rights statutes20.

Still today, people with disabilities must fight to live their lives independently. It is estimated that more than half of qualified21 Americans with disabilities are unemployed22, and a majority of those who do work are underemployed. About two-thirds live at or below the official poverty level.

Significant barriers, especially in transportation and public awareness23, prevent disabled people from taking part in society. For example, while no longer prohibited by law from marrying, a person with no access to transportation is effectively excluded from community and social activities which might lead to the development of long-term relationships.

It will only be when public attitudes advance as far as laws have that disabled people will be fully able to take their rightful place in society.

16. A “developmental" disability .

A. develops very slowly over time
B. is caused forces
C. occurs in youth and affects development
D. is getting more and more severe

17. Most disabled people used to die early because .

A. disabilities destroyed major bodily functions
B. they were not very well looked after
C. medical techniques were not available
D. they were too poor to get proper treatment

18. In the author's opinion, to enable the disabled people to take their rightful place in society.

A. more laws should be passed
B. public attitudes should be changed
C. government should provide more aids
D. more public facilities should be set up

19. Which of the following cannot be inferred from the passage ?

A. Many disabled people may remain single for their whole life.
B. The public tends to look down upon the disabled people.
C. The disabled people feel inferior to those surrounding them.
D. Discriminatory laws prevent the disabled from mixing with others.

20. The best title for this passage might be .

A. Handicaps of People with Disabilities
B. The difficulties of the Disabled
C. The Causes for Disabilities
D. Medical Treatments for Disabilities
