21.In the United States there are two major political parties, the Democratic and the Republican. The Democratic party is the older of the two, tracing its history back to the time of Andrew Jackson in 1820s. The Republican party, which followed the Federalist party and the Whigs, was organized in the 1850s primarily as an antislavery party. Since antislavery sentiment was strongest in the manufacturing area of the North and East, the Republican party logically adopted the protective tariff and other ideas furthering the growth of manufacturing in the United States. In 1860 the Democratic party was split into two factions, the northern and the southern Democrats, each putting up its own candidate for president. While the two factions together polled more votes than did the Republican ticket, the Republicans received a total higher than that of either faction of the Democrats, and Abraham Lincoln was elected president.From 1860 to the present day there have been many attempts to found new parties. But whenever a third party has had considerable appeal at the polls, one of both of the major parties in the next election has embraced the platform accounting for its appeal, and the third party has faded away.Over the years, therefore, the positions of the two major parties have been changing and adapting themselves to the currently important problems of public policy. At one time the Democratic party was considered to be a party standing up for state rights, and the Republican party a party representing the interests of business and industry. A clearcut difference between the two parties, however, has not existed for more than half a century. If one reads the platforms of the two parties, one finds that there is very little difference between them. Each party seems to be appealing to practically every group of voters. Unlike the political parties of Europe, and unlike the Conservatives and Laborites in England, the political parties in the United States are the collections of many disparate (不同的) elements.21.1 At first, the platform of the Republican party was centered around____.A. antislavery policies B. developing manufacturing C. settling the disputes between factions D. solving social problems
2. A railroad was being built all the way down the east coast off Florida, from Jacksonville to Miami and Negro workers were employed because they were cheap. A great many of them were in Daytona. Most of them had children. They were living in shacks worse than those in The Terry in Augusta. The children were running wild in the streets. Mary Bethune seemed to hear a voice say, "What is the place? Build your school there."Her husband, Albertus, wasn't so sure about her school. He thought Palatka was a pretty good place for them to live. Mary listened but she never gave up her idea. She knew that if she went to Daytona, Albertus would come too.One day she begged a ride for herself and her little boy with a family that was going to Daytona. It was only seventy miles away. But in 1904 the sand was deep on Florida roads. Practically no one had an automobile -- certainly not the poor family that gave Mary and little Albert a ride. So it was three dusty days after they left Palatka before they reached Daytona. There Mary hunted up the only person she knew, and she and little Albert stayed with this friend for a few days.As she had done in The Terry in Augusta, Mary walked up and down the poor streets of Daytona. She was looking for two things -- a building for the school she was determined to start and some pupils for that school.After a day or two, she found an empty shack on Oak Street. She thought this would do. The owner said she could rent it for $11.00 a month. But it wasn't worth that much. The paint had peeled off, the front steps wobbled so that she had to hang onto the shaky railing to keep from falling, the house was dirty, it had a leaky roof. In most of the windows the panes of glass were broken or cracked.Eleven dollars a month ! Mary said she only had Times="10".50. She promised to pay the rent as soon as she could earn the money. The owner trusted her. By the time she was sure she could have the building, she had five little girls from the neighborhood as her pupils.What a school! A rickety old house and five little girls! The little girls pitched in and cleaned the house. The neighbors helped with scrubbing brushes, brooms, hammers, nails, and saws. Soon the cottage could be lived in, but there were no chairs, no tables, no beds. There was no stove. However, there were no pots and pans to cook in, even if there had been a stove.Mary set about changing these things. She found things in trash piles and the city dump. Nobody but Mary would have thought of making tables and chairs and desks from the old crates she picked up and brought home. Behind the hotels on the beach she found cracked dishes, old lamps, even some old clothes. She took them home too. Everything was scoured and mended and used. "Keep things clean and neat" was her motto then; and as long as she lived the pupils in her school had to live up to that motto.Her little pupils had no pencils. They wrote with pieces of charcoal made from burned logs. Their ink was elderberry juice. What good was ink or a pencil if there was no paper to write on? Mary took care of that too.Every time she went to the store to get a little food, or a few pots and pans, she had each article wrapped separately. The pieces of wrapping paper were carefully removed and smoothed out. The little girls used this paper to write their lessons with their charcoal pencils.She needed a cookstove very badly but she couldn't pay for one. What should she do? Her little pupils had to have warm food.Unexpectedly, the problem was solved for her. One day a wrinkled old white neighbor said to her, "Can you read?"Mary said, "Yes.""Then will you read me this letter from my son? I can't find my glasses."Mary read the letter to her."Thanks," said the mother.Mary turned to go. "You're welcome."The old woman stood by her open door and thought a moment. Then she said, "I got an old cookstove and I don't need it. Would you want it?"(5分)2.1 How did Mary's husband, Albertus feel about going to Daytona?____(1分)A. He was strongly in favour.B. He was quite reluctant.C. He was definitely against it.D. He was not happy about the idea.
You should read more, as book is to your mind _______ water is to your body.(1分)
24.Early in my travels, I had noticed these“new things” under the sun, and since they occur in increasing numbers all over the nation, it is interesting to observe them. From the beginning of my travels I had noticed the sale lots where they were sold and traded, but then I began to be aware of the parks where they sit down in uneasy permanence.By talking to the managers of the parks and to the dwellers in this new kind of housing, I got to know that these trailers are wonderfully built homes. Some of them are even forty feet long and they have two to five rooms, and are complete with air-conditioners, toilets, baths, and televisions. The parks where they sit are equipped with every facility. When a mobile home is drawn to the trailer park (活动住屋的停车场)，water and electric power will be connected and the television antenna raised, and then the family settle down.The park men charge a small ground rent plus fees for water and electricity. Telephones are connected in nearly all of them simply by plugging in a jack (插座). Sometimes the park has a general store for supplies, if there are no supermarkets nearby. Parking difficulties in the towns have caused these trailers to move to the open country where they don’t have to pay town taxes. The fact that these homes can be moved does not mean that they do move. Sometimes their owners stay for years in one place. It is a totally new and appealing way of life to me. These homes are never cheap and often are quite expensive with all the thousand appliances we live by—dishwashers, automatic clothes washers and driers, refrigerators.(10分)24.1 The author noticed the “ new things” (Para.1）when .(2分)A. he worked in the countryB. he traveled on a sunny dayC. he traveled around the countryD. he tried to talk to manager in the park

21.Video recorders and photocopiers, even ticket machines on the railways, often seem unnecessarily difficult to use. Last December I bought myself a Video cassette recorder (VCR) described as “simple to use”. In the first three weeks I failed repeatedly to program the machine to record from the TV, and after months of practice I still made mistakes. I am not alone. According to a survey last year by Ferguson, the British manufacturer, more than one in four VCR owners never use the timer on their machines to record a programme: they don’t use it because they’ve found it far too hard to operate.So why do manufacturers keep on designing and producing VCRS that are awkward to use if the problems are so obvious?First, the problems we notice are not obvious to technically minded designers with years of experience and trained to understand how appliances work. Secondly, designers tend to add one or two features at a time to each model, whereas you or I face all a machine’s features at once. Thirdly, although find problems in a finished product is easily, it is too late by then to do anything about the design. Finally, if manufacturers can get away with selling products that are difficult to use it, it is not worth the effort of any one of them to make improvements.Some manufacturers say they concentrate on providing a wide range of features rather than on making the machines easy to use. But that gives rise to the question, “why can’t you have features that are easy to use?” The answer is you can.Good design practice is a mixture of specific procedures and general principles. For a start, designers should build an original model of the machine and try it out on typical members of the public-not on colleagues in the development laboratory. Simple pubic trials would quickly reveal many design mistakes. In an ideal world, there would be some ways of controlling quality such as that the VCR must be redesigned repeatedly until, say, 90 percent of users can work 90 per cent of the features correctly 90 per cent of the time.(10分)21.1 The author had trouble operating his VCR because ________.(2分)A. he had neglected the importance of using the timerB. the machine had far more technical features than necessaryC. he had set about using it without proper trainingD. its operation was far more difficult than the designer intended it to be
