Both the number and the percentage of people in the United States involved in nonagricultural pursuit expanded rapidly during the half century following the Civil War, with some of the most dramatic increases occurring in the domains of transportation, manufacturing and trade and distribution. The development of the railroad and telegraph systems during the middle of the nineteenth century led to significant improvements in the speed, volume, and regularity of shipments and communications, making possible a fundamental transformation in the production and distribution of goods.

In agriculture, the transformation was marked by the emergence of the grain elevators, the cotton presses, the warehouses, and the commodity exchanges that seemed to so many of the nation's farmers the visible sign of a vast conspiracy against them. In manufacturing, the transformation was marked by the emergence of a "new factory system" in which plants became larger, more complex, and more systematically organized and managed. And in distribution, the transformation was marked by the emergence of the jobber(中间商), the wholesaler, and 'the mass retailer(零售商). These changes radically altered the nature of work during the half century between 1870 and 1920.

To be sure, there were still small workshops, where skilled craftspeople manufactured products ranging from newspapers to cabinets to plumbing fixtures. There were the sweatshops in city tenements, where groups of men and women in household settings manufactured clothing or cigars on a piecework basis. And there were factories in occupations such as metalwork where individual contractors presided over what were essentially handicraft proprietorships that coexisted within a single building. But as the number of wage earners in manufacturing rose from 2.7 million in 1888 to 4.5 million in 1900 to 8.4 million in 1920, the number of huge plants like the Baldwin Locomotive Works in Philadelphia burgeoned (迅速成长), as did the size of average plant. (The Baldwin Works had 600 employees in 1855, 3,000 in 1875, and 8,000 in 1900.) By 1920, at least in the northeastern United States where most of the nation's manufacturing wage earners were concentrated, three-quarters of those worked in factories with more than 100 employees and 30 percent worked in factories with more than 100 employees.

What can be inferred from the passage about the agricultural sector of the economy after the Civil War?______

A.New technological developments had little effect on farmers

B.The percentage of the total population working in agriculture declined

C.Many farms destroyed in the war were rebuilt after the war

D.Farmers achieved new, prosperity because of better rural transportation

Is life today more dangerous than it used to be? It certainly seems that way.With the radiation emitted by our houses,the arsenic(砷)in the water and the toxic rays

coming out of cell phones,it isn't really safe to sleep,drink or talk.

Last week the entire Metro system in Washmgton had to close down because some- one might be blown onto the tracks during a hurricane.This week children in Washing- ton were not allowed to go to school for a whole day because streets were blocked by fallen trees and power 1ines,and traffic lights at some intersections weren't working.A previous generation might have walked around the fallen trees and looked both ways be- fore crossing the street,but the children of this generation clearly live in a much more dangerous world,and we need to protect them.

After Sept.11,2001,thousands of people swore off airplanes and began driving cars.In fact,the odds of being killed in a terrorist incident in 2002 were one in 9 mil- lion.In that same year,the odds of dying in a traffic accident were about one in 7,000.

By taking the precaution of not flying,many people died.

There are some clear psychological explanations for some of this.It's a fact that people fear man-made disasters(terrorism)far more than they fear natural disasters (hurricanes),and they are more afraid of things they do not control,which is why driv- ing a car does feel safer than flying in an airplane.Also,although I have no proof,I'll hazard a guess that people are disproportionately frightened by things they read about in the newspaper.By contrast,they are disproportionately willing to discount the evidence

of their own experience.If you look around your neighborhood,you’1l notice that the

water is clean—which it wouldn't necessarily have been 100 years ago—and that the food isn’t rotten or stale.

Life is far safer for the average American than it ever has tor j ust about anyboay at any other time in human history—and maybe that explains the ludicrous precautions that city officials and federal bureaucrats and everyone else feels obligated to take nowadavs to satisfy the public's demands.Now that we'Ve eliminated most of the things that

the human race once feared,we've just invented new ones to replace them.

31.Children are not allowed to go to school for the following reasons EXCEPT .

A.fallen trees

B.fallen power lines

C.a coming hurricane

D.broken traffic lights

32.It can be learned from the passage that the previous generation .

A.knew better how to avoid danger

33.Which is the accepted psychological explanation for people's fear as mentioned in the passage?

A.People are more afraid of things they do not know than things they are familiar with.

B.People are more afraid of dangers reported in newspapers than those they experience.

C.People are more afraid of flying in an airplane than riding a train.

D.People are more afraid of terrorist disasters than natural disasters.

34.It is indicated in the passage that in the past

A.life was more enjoyable

B.water was less clean and fresh

C.foods were of better taste and quality

D.streets were safer for children to cross

35.The author believes that .
