24、ny advantages. Above all, it offers people freedom to go wherever and whenever they want to go. The basic purpose of a motor vehicle is to get from point A to point B as cheaply, quickly, and safely as possible. However, to most people, cars are also personal fantasy machines that serve as symbols o

25、f power, success, speed, excitement, and adventure.In addition, much of the worlds economy is built on producing motor vehicles and supplying roads, services, and repairs for those vehicles. Half of the worlds paychecks are auto related. In the United States, one of every six dollars spent and one o

26、f every six non-farm jobs are connected to the automobile or related industries, such as oil, steel, rubber, plastics, automobile services, and highway construction.In spite of their advantages, motor vehicles have many harmful effects on human lives and on air, water, land, and wildlife resources.

27、The automobile may be the most destructive machine ever invented. Though we tend to deny it, riding in cars is one of the most dangerous things we do in our daily lives.Since 1885, when Karl Benz built the first automobile, almost 18 million people have been killed by motor vehicles. Every year, car

28、s and trucks worldwide kill an average of 250 000 people - as many as were killed in the atomic bomb attacks on Hiroshima and Nagasaki - and injure or permanently disable 10 million more. Half of the worlds people will be involved in an auto accident at some time during their lives.Since the automob

29、ile was introduced, almost three million Americans have been killed on the highways - about twice the number of Americans killed on the battlefield in all US wars. In addition to the tragic loss of life, these accidents cost American society about $ 60 billion annually in lost income and in insuranc

30、e, administrative, and legal expenses.Streets that used to be for people are now for cars. Pedestrians and people riding bicycles in the streets are subjected to noise, pollution, stress, and danger.Motor vehicles are the largest source of air pollution, producing a haze of smog over the worlds citi

31、es. In the United States, they produce at least 50% of the countrys air pollution.（分数：10.00）(1).Cars represent peoples _.（分数：2.00）A.occupationB.wealthC.life styleD.fame(2).According to the passage, the average number of people killed annually in traffic accidents around the world is _.（分数：2.00）A.18

33、e becoming less dangerousC.will produce less air pollution in the futureD.are killing more people in recent years than in the past(5).The title that suits the passage best is _.（分数：2.00）A.Automobile and EconomyB.Automobile and the EnvironmentC.The Problems with the AutomobileD.Advantages and Disadva

34、ntages of the Automobile八、Text 2(总题数：1，分数：10.00)Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed. Labor is one of the coun

35、trys resources which can be combined with other resources to produce the goods and services required by the community.Though the size of the workforce relies greatly on the size of the total population, there are several other aspects which also affect it. The age distribution of the total populatio

36、n has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old m work, then the available workforce would be lower than if there were an evenly spread age distribution. If the population grows rapidly from natural increase, i.

37、e. the number of births greatly exceeds the number of deaths, then as a total population increase the proportion in the workforce declines.Sometimes a population is described as aging, which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce t

38、here are inadequate numbers of young people entering it to take place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate.The age distribution

39、 of the population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonabl

40、e level of social services to the retired group. If the aged are to be cared for in special homes or hospitals, finance must be available for that purpose. If the size of the workforce is small relative to the total population, then the government tax receipts are relatively low and either the gover

41、nment has less money available to it or the workforce members have to be taxed more heavily.（分数：10.00）(1).Labor force is composed of _.（分数：2.00）A.people who are available to work and earn incomeB.self-employed people onlyC.only those who are looking for an employmentD.only the employees(2).The facto

42、r which does NOT influence the size of the workforce is _.（分数：2.00）A.the size of populationB.age distribution of the populationC.national economyD.natural increase(3).The conclusion which can be drawn safely from the second paragraph is that _.（分数：2.00）A.a population growth from natural increase lea

43、ds to a greater proportion of the workforceB.a large population does not necessarily mean a higher proportion of workforceC.the larger the number of the aged in a population, the higher the proportion of the workforceD.if the population has an evenly spread age distribution, the workforce will be lo

44、wer(4).When a population is said to be aging, _.（分数：2.00）A.more people are retiring than people entering the workforceB.the birth rate is growing rapidlyC.there is an oversupply of workforceD.young people outnumber old people(5).The population which is top-heavy with older people poses a problem to

45、_.（分数：2.00）A.the governmentB.the economyC.the workforceD.all of the above九、Text 3(总题数：1，分数：10.00)Hardly a week goes by without some advance in technology that would have seemed incredible 50 years ago. And we can expect the rate of change to accelerate rather than slow down within our lifetime. The

46、developments in technology are bound to have a dramatic effect on the future of work. By 2010, new technology will have revolutionized communications. People will be transmitting messages down telephone lines that previously would have been sent by post. Not only postmen but also clerks and secretar

47、ies will vanish in a paperfree society. All the routine tasks they perform will be carried on a tiny silicon chip so that they will be as obsolete as the horse and cart after the invention of the motor car. One change will make thousands, if not millions, redundant.Even people in traditional profess

48、ions, where expert knowledge has been the key, are unlikely to escape the effects of new technology. Instead of going to a solicitor, you might go to a computer which is programmed with all the most up-to-date legal information. Doctors, too, will find that an electronic competitor will be able to c

49、arry out a much quicker and more accurate diagnosis and recommend more efficient courses of treatment. In education, teachers will be largely replaced by teaching machines far more knowledgeable than any human being. Most learning will take place in the home via video conferencing. Children will still go to school though, until another place is created where they can make friends anti develop social skills.What can we do to avoid the threat of unemployment? We shouldnt hide our heads in the sand. Unions w
