Part II Reading Comprehension (35 minutes)
Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A., B., C. and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.
Questions 21 to 25 are based on the following passage
Scattered through the seas of the world are billions of small plants and animals called plankton (浮游生物). Most of these plants and animals are too small for the human eye to see.
They drift about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent of the grasses that grow on the dry land continents, and the comparison is an appropriate one. In potential food value, however, plankton far outweighs that of the land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates (碳水化合物) each year, the sea's plankton generates more than twice as much.
Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now, marine scientists have at last begun to study this possibility, especially as the sea's resources loom even more important as a means of feeding an expanding world population.
No one yet has seriously suggested that planktonburgers may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among marine scientists.
One type of plankton that seems to have great harvest possibilities is a tiny shrimplike creature called krill(磷虾). Growing to two or three inches long, krill provides the major food for the giant blue whale, the largest animal ever to inhabit the Earth. Realizing that this whale may grow to 100 feet and weigh 150 tons at maturity,it is not surprising that each one devours more than one ton of krill daily.
Krill swim about just below the surface in huge schools sometimes miles wide, mainly in the cold Antarctic. Because of their pink color, they often appear as a solid reddish mass when viewed from a ship or from the air. Krill are very high in food value. A pound of these crustaceans (贝类) contains about 460 calories― about the same as shrimp or lobster, to which they are related.
If the krill can feed such huge creature as whales, many scientists reason, they must certainly be contenders as new food source for humans.
21. Which of the following statement best describes the organization of the passage?
A. The author makes a general statement about plankton as a food source ad then moves to a specific example.
B. The author presents the advantages and disadvantages of plankton as a food source.
C. The author quotes public opinion to support the argument for farming plankton.
D. The author classifies the different food sources according to the amount of carbohydrate.
22. It can be inferred from the passage that krill is.
A. a kind of giant whale in the ocean
B. a kind of plankton
C. a kind of shrimp containing high carbohydrates
D. a kind of popular hamburger
23. According to the passage, why plankton is considered to be more valuable than land grasses?
A. It tastes better.
B. It's easier to farm.
C. It does not require soil.
D. It contains more carbohydrates.
24. Which of the following statements is NOT true?
A. The giant blue whale may grow to 100 feet and weigh 150 tons at maturity.
B. Some experts have predicted that planktonburgers will become popular in the foreseeable future.
C. Krill swim about just below the surface in huge schools sometimes miles wide, mainly in the cold Antarctic.
D. Krill contain about the same amount of calories as shrimp or lobster, to which they are related.
25. The word “school” in the sixth paragraph is closest in meaning to which of the following word?

Questions 26 to 30 are based on the following passage:
The idea of public work projects as a device to prevent or control depression was designed as a means of creating job opportunities for unemployed workers and as a pumpprimping device to aid business to revive. It was conceived during the early years of the New Deal Era (19331937). By 1933, the number of unemployed workers had reached about 13 million. This meant that about 50 million people ― about onethird of the nation―were without means of support. At first, direct relief in the form of cash or food was provided to these people. This made them receivers of government charity. In order to remove this stigma and restore to the unemployed some measure of respectability and human dignity, a plan was devised to create governmentally sponsored work projects that private industry would not or could not provide. This would also stimulate production and revive business activity.
The best way to explain how this procedure is expected to work is to explain how it actually worked when it was first tried. The first experiment with it was the creation of the Works Project Administration (WPA). This agency set up work projects in various fields in which there were many unemployed. For example, unemployed actors were organized into theater projects, orchestras were organized for unemployed musicians, teaching projects for unemployed teachers, and even writers projects for unemployed writers. Unemployed laborers were put to work building or maintaining roads, parks, playgrounds, or public buildings. These were all temporary work relief projects rather than permanent work opportunities.
More substantial work projects of a permanent nature were organized by another agency, the Public Works Administration (PWA). This agency undertook the planning of construction of schools, houses, post offices, dams and other public structures. It entered into contracts with private construction firms to erect them, or it loaned money to local or state governments which undertook their construction. This created many jobs in the factories producing the material as well as in the projects themselves, and greatly reduced the number of unemployed.
Still another agency which provided work projects for the unemployed was the Civilian Conservation Corps (CCC). This agency provided job opportunities for youths aged 16 to 20 to work in national parks or forests clearing land, guarding against fires, building roads, or doing other conservation work. In the event of a future depression, the federal government might revive any or all of the above methods to relieve unemployment and stimulate business.
26. What is true about the “public work projects"?
A. They were supposed to function as a pumpprimping device to start more new businesses.
B. They were conceived when the New Deal Era was drawing to an end.
C. They were provided to unemployed people in the form of cash or food.
D. They were supposed to provide job opportunities to the unemployed and revive business activities.
27. It is suggested in the passage that the PWA .
A. was first tried as an initiative effort to restore to the unemployed some measure of respectability and human dignity
B. set up work projects in various field in which there were many unemployed
C. undertook the planning of various constructions to create jobs in the factories producing the materials as well as in the projects themselves
D. provided job opportunities for young people from 16 to 20
28. Which of the following best describes the structure of the passage?

C. About 150 million.D. About 40 million.
Questions 31 to 35 are based on the following passage:
It's all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. Everybody knows that the nicest men become monsters behind the wheel. It is all very well, again, to have a tiger in the tank, but to have one in the driver's seat is another matter altogether. You might tolerate the odd roadhog, the rude and inconsiderate driver, but nowadays the wellmannered motorist is the exception to the rule. Perhaps the situation calls for a Be Kind to Other Drivers campaign, otherwise it may get completely out of hand.
Road politeness is not only good manners, but good sense too. It takes the most coolheaded and goodtempered of drivers to resist the temptation to revenge when subjected to uncivilized behavior. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions. But such acknowledgements of politeness are all too rare today. Many drivers nowadays don't even seem able to recognize politeness when they see it.
However, misplaced politeness can also be dangerous. Typical examples are the driver who brakes violently to allow a car to emerge from a side street at some hazard to following traffic, when a few seconds later the road would be clear anyway; or the man who waves a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to. It always amazes me that the highways are not covered with the dead bodies of these grannies.
A veteran driver, whose manners are faultless, told me it would help it motorists learnt to filter correctly into traffic streams one at a time without causing the total blockages that give rise to bad temper. Unfortunately, modern motorists can't even learn to drive, let alone master the subtler aspects of roadsmanship. Years ago the experts warned us that the carownership explosion would demand a lot more giveandtake from all road users. It is high time for all of us to take this message to heart.
31. According to the passage, the author would most probably disagree with which of the following statements?
A. It is high time for motorists to learn good manners on the road.
B. Drivers today are typically goodmannered and able to acknowledge politeness.
C. Politeness, while being misplace, could be dangerous too.
D. It is very hard to control one's temper when one is treated with bad manners.
32. The word “veteran” in the last paragraph most probably means .
A. retiredB. elderly
C. experiencedD. goodmannered
33. Which of the following statements is true?
A. A Be Kind to Other Drivers campaign is being launched lest the situation get out of control.
B. Experts predicted years ago that the increase of the number of automobiles would not create tolerance and friendliness among drivers on the roads.
C. A friendly nod or a wave of acknowledgement in response to an act of politeness can be vital in creating a friendly atmosphere in modern traffic conditions.
D. Old ladies usually have good manners in driving.
34. What does the word inconsiderate in the first paragraph mean?
A. not thinking of other peopleB. inexperienced
C. incorrigibleD. inconsistent
35. According to the author, what is to blame for bad manners on the roads?
A. traffic jamsB. cost of petrol
C. quick pace of modern lifeD. lack of politeness
Questions 36 to 40 are based on the following passage: 
One of the major problems of nuclear energy is the inability of scientists to discover a safe way to dispose of the radioactive wastes which occur throughout the nuclear process. Many of these waste remain dangerously active for tens of thousands of years, while others have a life span closer to a quarter of a million years. Various methods have been used to date, but all have revealed weaknesses, forcing scientists to continue their search.
The nuclear process involves several stages, with the danger of radioactivity constantly present. Fuel for nuclear reactors comes from uranium ore, which, when mined, spontaneously produces radioactive substances as byproducts. This characteristic of uranium ore went undetected for a long time, resulting in the deaths, due to cancer, of hundreds of uranium miners.
The United States attempted to bury much of its radioactive waste material in containers made of steel covered in concrete and capable of holding a million gallons. For a long time it was believed that the nuclear waste problem had been solved, until some of these tanks leaked, allowing the radioactive wastes to seep into the environment. Canada presently stores its nuclear waste in underwater tanks, with the longterm effects largely unknown.
However, plans are under consideration for aboveground storage of spent fuel for reactors. These plans include the building of three vast concrete containers, which would be two stories high and approximately the length and width of two football fields. Other suggestions include enclosing the waste in glass blocks and storing them in underground caverns, or placing hot containers in the Antarctic region, where they would melt the ice, thereby sinking down about a mile. This idea has since been abandoned because of the possible adverse effect on the ice sheets.
36. What does the passage mainly discuss?
A. The disposal of nuclear wastes.
B. The advantage of underground storage of radioactive wastes.
C. Possible adverse effects of radioactive wastes on the Antarctic Region.
D. A comparative study of the disposal of radioactive waste plans in the United States and Canada.
37. It is suggested in the passage that the deaths of uranium miners resulted from .
A. the leak of some of the radioactive waste containers buried underground.
B. drinking water polluted by underwater radioactive waste containers.
C. cancer caused by contact with radioactive substances.
D. longterm adverse effect of radioactive substances on their health.
38. Which of the following statements is true about nuclear wastes according to the passage?
A. Many of the nuclear wastes can remain dangerously active for tens of thousands of years.
B. People haven't come up with any solution to the disposal of nuclear wastes so far.
C. Many uranium ore miners died from cancer even though the dangers of mining uranium ore had long since been detected.
D. They are spontaneously produced in nuclear waste disposal.
39. Hot containers of nuclear wastes to be put in Antarctic region would .
A. not be harmful to the environment
B. remain under sea
C. remain above ice sheets
D. be cooled off by the surrounding ice sheets
40. It is implied in the passage that the primary difficulty in seeking a safe way to dispose of nuclear wastes is caused by.
A. scientists' failure to detect the dangers of radioactive substances in early history of uranium ore mining.
B. nuclear reactors producing dangerous byproducts.
C. the harmful nature of nuclear wastes coupled with their lengthy life span.
D. the nuclear process involving the danger of radioactivity at its every stage.

3.   the   People once think that the Earth was flat and that you could fall the edge. Most of us now think of the planet as a sphere. It is quite useful to think of the Earth and its atmosphere as to being rather like an onion―that is, a ball made up of layers, although, unlike an onion, each layer is made of different material.
One of the stories was created by the writer Jules Verne described a journey to the center of the Earth, but at the Earth's center it would be rather uncomfortable because the inner core of our planet is thought to be made an alloy (合金) of nickel and iron at a pressure some four million times greater than that which we experience at the surface. Surrounding this inner core is an outer core it seems to be liquid and is made of nickel and iron together with a lighter element such as silicon or sulphur.
It is very difficult to discover what it is like within the Earth. Information has collected from the study of earthquake waves, which react differently in rocks of different densities and different degrees of solidity. Volcanoes also provide evidence as they throw to the surface materials from great depths. There is one another source of information― meteorites which fall from space and are thought to represent the composition of the Universe as a whole.[]71.

Part III Short Answer Questions (15 minutes)
Directions: In this part, there is a short passage with five questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words (not exceeding 10 words).
At a very low temperature the molecules in a crystal of iodine lie rather quietly in their places in the crystal. As the temperature increases, the molecules become more and more agitated; each one bounds back and forth more and more vigorously in the little space left for it by its neighbors. This increase in molecular motion with increase in temperature is termed thermal oscillation.
A molecule on the surface of the crystal is held to the crystal by the forces of attraction that its neighboring molecules exert on it. These forces, which operate between all molecules when they are close together, are called van der Wals attractive forces, after the Dutch physicist J. D. Van der Wals, who first gave a thorough discussion of intermolecular forces within gases and liquids.
These attractive forces are quite weak; hence, occasionally, a certain molecule will become so agitated as to break loose from its neighbors and fly off into the surrounding space. If the iodine crystal is in a vessel, there will soon be present within the vessel, through this process of evaporation, a large number of free molecules. The free molecules constitute iodine vapor or iodine gas, which is violet in color and has a characteristic odor.
It may seem surprising that molecules on the surface of a crystal should evaporate directly to a gas, but, in fact, the process of slow evaporation of a crystalline substance is not uncommon. Solid pieces of naphthalene(萘), used in moth balls, left out in the air slowly decrease in size, because of the evaporation of molecules from the surface of the solid. Snow may disappear from the ground without melting, by evaporation of the ice crystals at a temperature below that of their melting point. Evaporation is accelerated if a wind is blowing to take the water vapor away from the immediate neighborhood of the snow crystals and to prevent the vapor from condensing again on the crystals.
The characteristic feature of a gas is that its molecules are not held together but are moving about freely in a volume rather large compared with the volume of the molecules themselves. The attractive forces between the molecules still operate whenever two molecules come close together, but usually these forces are negligibly small because the molecules are far apart.
Questions:
86. The passage suggests that when there is an increase in temperature, the molecules will .
87. Van der Wals was the first scientist to give a thorough discussion of .
88. The author compares the evaporation of molecules on the surface of a crystal into the air to the evaporation of .
89. Molecules of iodine occasionally break loose from their neighboring molecules because .
90. The attractive forces between molecules of gases won't operate until .

Passage One
Indian summer is a short period of extremely fair weather and mild days in autumn. It comes in late October or early November while the leaves are turning color and falling from the trees. It has no definite day of beginning or ending.
The pleasant weather follows the autumn's first period of cold, wintry days. The days become warmer but the nights remain chilly. An Indian summer moon often has a soft yellow or orange hue. Indian summer lasts from a week to ten days and sometimes for two weeks. Then winter starts. Indian summer is caused by a large mass of warm tropical air. South winds carry these masses northward. The American Indians enjoyed Indian summer and called it a gift of a favorite god―the god of the Southwest.
Questions 11 to 13 are based on the passage you have just heard.
11. At what time of the year does Indian summer come?
12. What causes Indian summer?
13. Which of the following cannot be definitely said about American Indians?
Passage Two
      Kuwait is a country which is quite small, but which is very rich. It has a population of a little more than a million, and it is situated at the North end of the Persian Gulf. This small desert country is one of the world's leading oil producers, and it has approximately fifteen per cent of the world's known petroleum reserves. Since the discovery of oil in 1938, Kuwait's rulers have turned the country into a prosperous welfare state. It has free primary and secondary education, free health care and social services; and the Kuwaitis do not have to pay any personal income tax for those services. The rate of literacy is high and constantly growing. The University of Kuwait was opened in 1966, but many of the Kuwaiti students still study in colleges and universities abroad, at state expense. Kuwait is, needless to point out, an Arab country, and about 99 per cent of the people who live there are Moslems. But fewer than half of these Moslems are actually citizens of Kuwait. This is because there are many Moslem immigrants living and working there. Many of these recent immigrants have come from all over the Arab world―from places like Egypt, Syria, Lebanon, from Oman, and from the Sudan. Indians, Pakistanis, and Iranians live and work in Kuwait, too. The other one per cent of the population, in other words, the nonMoslems, are recent immigrants who were attracted by the opportunities to work for the oil companies. There are several thousand Europeans and Americans in Kuwait. Many of them are employed by the oil companies.
Questions 14 to 16 are based on the passage you have just heard.
14. What percentage of the world's known petroleum reserves does Kuwait have?
15. According to the passage, the welfare system of Kuwait provides all of the following except .
16. When was the University of Kuwait opened?
Passage Three
      Scientists have discovered that plants themselves produce many poisonous chemicals for defense against insects. But insects have developed ways of dealing with them and, in fact, have been eating plants for about 250 million years. Now insects are using these same mechanisms to deal with manmade poisons―insecticides. This is why resistance of insects to insecticides has developed so rapidly.
      What should be done? Scientists studying the problem suggest that farmers use less insecticides. At the moment, farmers regularly spray crops as a precaution against problems that are caused by large numbers of pests. They should, instead, spray only where pests have actually been seen. Secondly, farmers could use a combination of two or three insecticides at once. To survive, the insects would need to become resistant to two or more insecticides at the same time.
      The most surprising suggestion, perhaps, is that at certain times of the year, farmers should actually try to attract insects onto the crops they are trying to protect. The new insects will mate with those which survived from a certain kind of insecticide and will lessen the latter's resistance to it.
      Scientist hope that these and other measures will postpone the day when farmers and scientists will have to stand by while new superbugs which may be resistant to all poisons invade our farms and devour our crops.
Questions 17 to 20 are based on the passage you have just heard.
17. What conclusion can be drawn from the scientists' observation?
18. Why did the resistance of insects to manmade insecticides develop so rapidly?
19. Which of the following is NOT included in the scientists' suggestions?
20. What can be inferred from the passage?
Section C (Compound Dictation)

Although twins have always been a source of curiosity, they are not so uncommon statistically,since they occur once in every eightysix births.
About onethird of all twins are identical, or singleegg twins. Identical twins have the same genes and, hence, the same sex, hair, eyes, blood type, and bone and tooth structure. Some identical twins are mirror images of each other. For example, one may be lefthanded, the other righthanded. As young children, some identical twins may develop their own private language. Identical twins have an especially keen intuition, and they often seem to think and dress alike even when away from each other. In fact, even when they are separated at birth and raised apart, identical twins develop startling similarities. They may pursue the same careers, have the same interests, or die within days of each other.
In contrast to identical twins, fraternal twins inherit a separate assortment of genes and are not necessarily of the same sex. In some families there is a hereditary tendency to produce fraternal twins, but identical twins occur at random in the population.
