PASSAGE 1 $HjKELoJ<
Scientists now tend to agree that the noise level for potential hearing loss begins at about 70 decibels. Some of them are very concerned because normal daily life exposes people to noise levels of about 70 decibels even inside their homes. Cities have always been noisy, but noise is now spreading to areas that were quiet just a few years ago.
Clearly, something must be done or noise will seriously and permanently maim the population. Fortunately, the knowledge and methods to control noise already exist. As a matter of fact, this is one instance where the knowledge about the effects on human life and on the environment.
There are two common means for control. The first is reducing its source, and the second is changing the sound path by distance or by shielding.
The second approach is being used more often today as people become more aware of the danger of noise. New building codes require better sound insulation in homes and apartments. More and more towns are passing zoning ordinances that try to segregate noisy factories or airports from residential areas. Sound-absorbent materials and construction designed to block sound paths are slowly coming into use in offices and homes. New highways are being built to redirect traffic noise up and away from nearby areas. Aircraft are increasingly being required to use reduced power flights around airports.
There are many examples of available noise control methods that are not being used. More flexible building codes would permit the use of quieter kinds of plumbing pipes. Sound-absorbing materials can reduce the noise of motors and engineers. Power generators can be quieted with baffles, exhaust silencers, and sound absorbers. Truck machines is the same or only slightly higher than that of the current noisy ones. Even though the new equipment may cost more initially, it can prove more profitable in the long run. The new jumbo jets, for example, are quieter than the older ones, yet they are more powerful and carry twice as many passengers.
All of these methods are only partial measures as noisy levels continue to rise. Most specialists in field agree that much of solution must come from eliminating some of the noise at its source, therefore saving through prevention the large costs of hearing loss.
21. The noise level for possible hearing loss begins about__________
A. 30 decibels               B. 75 decibels
C.100 decibels               D. none of above
22. Jet pilots are being advised to land__________
A. on longer runways.        B. from nearby areas.
C. after dark.                C. with reduced power.
23.How many practical means for controlling noise does the author present?
A. one.                    B. two.
C. three.                   D. four.
24. The reader can assume that airport of the future will__________
A. have runways in north-south pattern.
B. be located in unpopulated areas.
C. be required to warn passengers of high noise levels.
D. in nearby areas.
25. Jumbo jets are mentioned as examples of__________
A. efficient transportation with low level of noise.
B. vehicles that cause serious air pollution.
C. scientific advances that do more harm than good.
D. quieter and older vehicle.
PASSSAGE 2 l*[.
Every time a person eats something he makes a nutritional decision. He accepts or rejects the food available to him at home for meals or snacks. Or he selects food for himself at many places in the community, such as supermarkets, drive-ins, restaurants, and food counters in drugstores. These selections make a difference in how an individual looks, how he feels, and how well he can work and play.
When a good assortment of food in appropriate amounts is selected and eaten, the consequences are more likely to be a desirable level of health and enough energy to allow one to be as active as he needs and wants to be. When choices are less than desirable, the consequences are likely to be poor health or limited energy or both.
Studies of diets of individuals in the United States show that food selection is a highly individual matter, even among young children Furthermore, far too many individuals of all ages are making poor choices day after day and are either now living with the consequences or will be in the future.
Nutritionists and workers in allied professions have been concerned about helping people learn to select and enjoy a wide variety of food combinations that can add up to a good diet.
Most people believe that they are well fed––that the choices they make are good ones. After all, they are not really sick, neither are they hungry. However, their nutrition is usually poor in one respect or another. Milk and milk products, such as cheeses, ice cream or milk, buttermilk, and yogurt, are often slighted. Then people may skip many fruits and vegetables, particularly those that are good sources of vitamins A and C. These include dark green, leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables, such as cabbage, tomatoes, and green peppers.
Every American has the right to choose to be uniformed about nutrition as well as to be informed. If a person believes that she is well fed, attitudes, habits, and information cannot be forced upon her.
There are life situations, however, that tend to cause an individual to want to know how to make the best choices. For example, a young couple is starting a family and must prepare food for young children.
26. Food preference in America is _____________
A. culturally oriented.    B. inherited.
C. individualistic.       D. according to ages.
27. Good amounts of vitamin A can be found in ____________
A. celery              B. banana.
C. milk.               D. cabbage.
28. According to the author, nutritionists are concerned with _________
A. improving the vitamin content of processed foods.
B. restricting the manufacture of high cholesterol foods.
C. informing the public about wholesome foods.
D. helping people enjoying uninformed about nutrition.
29. Some people judge their nutrition by the ____________
A. status of their health.
B. grocery stores where they shop.
C. amount of protein in their diets.
D. food they took.
30. The author advocates ____________________
A. requiring high school students to take courses on nutrition.
B. making information on nutrition available to the public.
C. forcing food manufacturers to list ingredients on packages.
D. people has the right to choose food.
PASSAGE 3 .eXIbd<C
Almost since the beginning of mankind, governments have been recording the numbers of their populace. The first known census report took place in 3800 B. C. in Babylonia for the purpose of deciding who should pay taxes. As time went by, governments found other, more creative uses for knowing their numbers. Egyptian King Romans II used the census not only to determine who should pay taxes, but also to figure out how to divide land for farming and to decide who could provide manpower for various government projects. These new ideas came about in the mid-1200s--B.C.
William the Conqueror brought the concept of census taking to England in 1085. All landowners were required to name their holdings for the purpose of taxation. By the fifteenth century, Tudor kings found a new twist to the Egyptians’ use of the census. They too used the population count as a means of getting ready manpower for important government projects-namely, replenishing troops in the ongoing battles in western Europe.
A rebellious tide swept over England, however, in the mid-1700s. A bill to authorize a regular census was defeated in Parliament on the grounds that it would give valuable information to England’s enemies. But the tide of rebellion soon turned, and in 1800 England established its first regular census.
Meanwhile the United States had already had an ongoing census for ten years. It was authorized in the Constitution for the purpose of deciding how many members of constitution! Article also established that the census would be taken in 1790 and every ten years thereafter. And so it has.
Since its beginning, the American census has gone through many changes. Today the census provides more than a count of the people who live here. It takes polls on transportation, economic planning, and agriculture. The census also provides data for most government agency statistics. Such as the unemployment rate.
Counting costs have risen since 1790. The government spent about a penny per person to count past-Revolutionary Americans. Today the census costs $250 million-more than a dollar per person. That’s a long way since 3800 B.C.
31. The first known census report took place in Babylonia in__________
A. 1085                     B. 1200 B.C.
C. 3800 B.C.                 D. 1790.
32. The first census was created for the sole purpose of _____________
A. counting available troops.
B. dividing farmland.
C. providing manpower
D. taxing the populace
33. The American census today costs the government approximately____
A. $0.1/person              B. $10/person
C. $1.00/person             D. $10.00 /person
34. Parliament defeated a bill authorizing a regular census because it____
A. might give valuable news to England.
B. would give England’s enemies cause for rebellion.
C. would be too expensive.
D. might disclose information to England’s enemies.
35. The author implies the American census is ___________
A. relatively inexpensive to conduct.
B. important to various government branches.
C. an exact count of the citizenry.
D. fairly expensive before 1790.
PASSAGE 4 .h~)|"uzW
It didn’t happen overnight. The problem of polluted air has been festering for centuries.
Suddenly the problem of air pollution is becoming critical and is erupting right before our eyes. Not only do our eyes burn as they focus through murky air, but when the air clears, we see trees and vegetation dying. We must realize that this destruction can no longer be pinned to some mysterious cause. The one major culprit is air pollution.
Today’s air pollution is an unfortunate by-product of the growth of civilization. Civilized man desires goods that require heavy industrialization and mass production. Machines and factories sometimes pollute and taint the air with substances that are dangerous to man and the environment. These substances include radioactive dust, salt spray, herbicide and pesticide aerosols, liquid droplets of acidic matter, gases, and sometimes soil particles. These materials can act alone to irritate objects and forms of life. More dangerously, they join together to act upon the environment. Only lately have we begun recognizing some of their dangerous consequences.
Scientists have not yet been able to obtain a complete report on the effects of air pollution on trees. They do know, however, that sulfur dioxide, fluorides, and ozone destroy trees and that individual trees respond differently to the numerous particulate and gaseous pollutants. Sometimes trees growing in a single area under attack by pollutants will show symptoms of injury or will die while their neighbors remain healthy. Scientists believe this difference in response depends on the kind of tree and its genetic makeup. Other factors, such as the tree’s stage of growth and nearness to the pollution source, the mount of pollutants, and length of the pollution attack also play a part .In short, whether or not a tree dies as a result of air pollution depends on a combination of host and environmental factors.
For the most part, air pollutants injure trees. To conifers, which have year-round needles, air pollution causes early balding. In this event, trees cannot maintain normal food production levels. Undernourished and weakened, they are open to attack by a host of insects, diseases, and other environmental stresses. Death often follows.
Air pollution may also cause hardwoods to lose their leaves. Because their leaves are borne only for a portion of the year and are replaced the following year , air pollution injury to hardwoods may not be so severe.
36. The author attributes today’s air pollution to ________
A. the growth of civilization.   B. man’s carelessness
C. environmental imbalance    C. some mysterious cause.
37. The resistance of some trees to disease can be traced to ______
A. protective foliage           B. thick bark
C. genetic makeup             D. tainted air
38.Air pollution causes the most damage to _______
A. hardwoods                B. conifers
C. fruit trees                 D. fluorides
39.The author implies that the greatest source of pollution is ________
A. heavy industry             B. chemical processing plants
C. urban expansion            D. salt spray
40. We can conclude that ___________
A. air pollution is easier to control than water pollution
B. the problem of polluted air is a problem overnight
C. the impact of air pollution has been known for centuries
D. research on the efforts of air pollution is incomplete.

It is not long since conditions in the mine were worse than they are now. There are still _61_a few very old women who in their youth have worked _62_, with harness round their waists, and a chain _63_ passed between their legs, crawling on all _64_ and dragging tugs of coal. They used to go on _65_ this even when they were pregnant.
And _66_ produce without pregnant women dragging it _67_ and fro, I fancy we should let them do it _68_ than deprive ourselves of coal. But most of the time, of course, we should _69_ to forget that they were doing it. It is _70_ with all types of manual work; it keep us alive, and we oblivious of its existence .More than anything _71_, perhaps, the miner can stand as the type of manual worker, not only because it is so vitally necessary and _72_ so _73_, that we were capable _74_ forgetting it as we forget the blood in our veins. In _75_ way it is even humiliating to watch coal-miners working. It raises in you a momentary doubt _76_ your own status as an “intellectual” and a superior person generally.

Part V Translation (15points) v7/k0D .
Directions: Read the following passage carefully and then translate it into Chinese .Write your translation on the ANSWER SHEET(2). d&lT/S
Two teams of astronomers using the Hubble Space Telescope have overturned several decades of conjecture and theory by ruling out the possibility that small, dim stars make up most of the mass in the universe.
Until now, small stars known as faint red dwarfs were considered ideal candidates for the so-called “dark matter” that is believed to account for more than 90 percent of the mass of the universe
All visible celestial objects, such as planets, stars and galaxies, are believed to account for only 10 percent of mass of the universe, The rest of the “missing mass” is presumably invisible because it does not emit or reflect light, or the light is too feeble to be detected. But dark matter can be indirectly detected due to its gravitational influence on other visible objects.
According to Bacall, professor of nature science at the Institute of Advanced Study in Princeton, New Jersey and leader of one of the teams, the nature of dark matter, and its abundance, are among the mast important questions in modern cosmology today.
The ultimate fate of the universe will be determined by the amount of dark matter present. If there is not enough dark matter to bind the universe together gravitationally, it could continue expanding forever. If there is enough mass to hold the universe together gravitationally, the universe may slow down its expansion, come to halt and begin to contract and eventually collapse.
