16、the new age of science and technology since the Second World War. Everything has speeded up to a tremendous rate. Information is immediate, nobody has to wait to hear any news. There is a television set in every house. There is instant printing which has changed the way that offices and the universi

17、ties run.But perhaps the biggest change is the telephone. People no longer write letters to one another. They pick up the telephone. Every house has at least two, sometimes three, four and five telephones. Every office has many telephones. It speeds things up. And its cost is not much.Perhaps the bi

18、ggest difference is in the growth of computers. Computers can think, can remember, can calculate faster than any human brain. A computer can hold more than a million facts in its memory. There are computers that are so big they would fill this entire auditorium with machinery. Businesses and banks a

19、re now managed by computers. Parts of the government are managed by computers. Students grades, their marks are all managed by computers.However, if a computer makes a mistake about one of you, it is terribly difficult to correct that mistake. And sometimes a computer does make mistake, never learne

20、d by another computer and the same mistake will go into other computers. So in many ways people have become the servants of computers who are bigger and cleverer than they are. Of course, computers speed up every operation because computers can immediately record, remember facts and produce new info

21、rmation that it combines with these facts. It makes science possible. Modern science would not be possible without the computers to do the calculations.Life is complicated. People need to know many technical skills to get money from a bank. You have to know how to work the automatic teller that will

22、 give you your money. You have to know how to use the new punch button telephones. Everything is very complicated. Many Americans find it so complicated, that they try to escape by drinking alcohol. Alcoholism is a major disease in America. Some people take drugs and some people belong to strange re

23、ligion looking for some meaning in their life. I think perhaps you read about the terrible event in Guyana, when people who belong to a strange religion all committed suicide. This sort of thing would not have happened fifty years ago. It is a by-product of an age that has become too complicated for

24、 people to live in happily.There are many contradictions in American society. Because of the complex way of life people are no longer the optimistic, self- reliant free people that they were when they were pioneers, when they were conquering the new land. Now people are becoming more pessimistic. Ve

25、ry often they are lonely. The doctors who have the most work are psychiatrists trying to help people find ways that they can again be happy. Often efficiency replaces good quality.We still have two classes of people. Too much money is still in the hands of too few people. The rich capitalists no lon

26、ger wear black hats and stripped trousers. They have facesthat nobody knows because now they are called the “multi- national corporations. “They are the great faceless companies like General Motors, General Fords, United States Steel. There are no longer any faces like Mr. Rockefeller or Mr. Ford. T

27、hey have become faceless forces, which control our government and control the money. The poorest class is still mostly made up of black people, minority people, Spanish speaking Americans. And the poorest people have not benefited from the new age of science and technology. So Americans are no longe

28、r the happy carefree people that they once were.（分数：5.00）(1).According to the passage, the characteristic of a highly technological society is _.（分数：1.00）A.its electronic technologyB.peoples way of livingC.wide use of televisionD.its rapidness and efficiency in doing things(2).Which of the following

31、 society, _.（分数：1.00）A.so people like it better than beforeB.but there is still a big gap between different classesC.all the people there lead a very happy lifeD.all the industries and companies are in the hands of the goverment七、TEXT B(总题数：1，分数：5.00)The dark smoke that comes out of stacks or from a

32、 burning dump contains tiny bits of solid or liquid matter. The smoke also contains many gases, most of which cannot be seen. Altogether, they make up the serious problems of air pollution. In so many places it keeps us from seeing the sun, irritates our eyes, causes us to cough, and makes us ill.Ai

33、r pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had “black snow“ from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem.Air polluti

34、on can kill babies, older people , and those who have respiratory (呼吸道的) diseases. In London, in 1952, four thousand people died in one week as a result of a serious air-pollution episode. In 1948, in the small town of Donora, Pennsylvania, twenty people died in a four-day period of bad air pollutio

35、n.At levels often found in cities, air pollution increases the risks of certain lung diseases, such as emphysema, bronchitis, and asthma. Of course, smoking and other factors help to cause these illnesses, too, but these cases have increased greatly during recent years as air pollution has become wo

36、rse. Air pollution can cause both airplane and auto accidents because it cuts down visibility. There are other possible health dangers from air pollution that we dont know much about. For example, scientists are trying to find out whether chemicals that reach us from the air may cause changes in our

37、 cells.These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the many chemicals we are apt to take into our bodies from air, water, food, and even medicines act together to affect our health and the way our bodies work. That is another reason

38、why it is so important to begin to control pollution now instead of waiting until we learn all the answers.Air pollution costs us a lot of money. It soils and corrodes our buildings. It damages farm crops and forests. It has a destructive effect on our works of art. The cost of all this damage to ou

39、r government is astronomical. It would be much more worthwhile, both for us and for the environment, to spend our tax dollars on air pollution control.（分数：5.00）(1).The author mentions people dying of air pollution in _.（分数：1.00）A.IllinoisB.PennsylvaniaC.New JerseyD.Washington(2).Air pollution causes

41、mined _.（分数：1.00）A.all of the effects of pollution on the human bodyB.how pollution can be controlled successfullyC.when the atmosphere first became pollutedD.how to wash the black snow clean(5).We can conclude that _.（分数：1.00）A.civilization may be doomed if pollution is not controlledB.pollution is

42、 more serious in Europe than it is in AmericaC.most people do not know that pollution is a serious problemD.black snow is not so serious compared with white snow八、TEXT C(总题数：1，分数：5.00)In the late 1960s many people in North America turned their attention to environmental problems, and new steel-and-g

43、lass skyscrapers were widely criticized: ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities.Skyscrapers are also lavish consumers, and wasters of electric power. In one recent year, the addition of 17 million square fe

44、et of skyscraper office space in New York City raised the peak daily demand for electricity by 120, 000 kilowatts-enough to supply the entire city of Albany, New York, for a day.Glass-walled skyscrapers can be especially wasteful. The beat loss ( or gain) through a wall of half-inch plate glass is m

45、ore than ten times that through a typical masonry wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce gla

46、re as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.Skyscrapers put a severe strain on a citys sanitation facilities, too. ( If fully occupied, the two World Trade Center towers in New York City would alone generat

47、e 2.25 million gallons of raw sewage each year- as much as a city the size of Stanford, Connecticut, which has a population of more than 109, 000. )Skyscrapers also interfere with television reception, block bird flyways, and obstruct air traffic. In Boston in the late 1960s, some people even feared

48、 that shadows from skyscrapers would kill the grass on Boston Common.Still, people continue to build skyscrapers for all the reasons that they have always built them-personal ambition , civic pride, and the desire of owners to have the largest possible amount of rentable space.（分数：5.00）(1).The main

49、purpose of the passage is to _.（分数：1.00）A.compare skyscrapers with other modern structuresB.describe skyscrapers and their effect on the environmentC.advocate the use of masonry in the construction of skyscrapersD.illustrate some architectural designs of skyscrapers(2).According to the passage, what is one disadvantage of skyscrapers that:
