单选题Passage 7 No reference book, perhaps no book of any kind except the Bible, is so widely used as "the dictionary". Even houses that have few books or none at all possess at least one dictionary; most business offices have dictionaries, and most typists keep a copy on their desks; at one time or another most girls and boys are required by their teachers to obtain and use a dictionary. Admittedly, the dictionary is often used merely to determine the correct spelling of words, or to find out the accepted pronunciation, and such a use is perhaps not the most important from an intellectual point of view. Dictionaries may, however, have social importance, for it is often a matter of some concern to the person using the dictionary for such purpose that he should not suggest to others, by misspelling a word in a letter, or mispronouncing it in conversation, that he is not "well-bred", and has not been well educated. Yet, despite this familiarity with the dictionary, the average person is likely to have many wrong ideas about it, and little idea of how to use it profitably, or interpret it rightly. For example, it is often believed that the mere presence of a word in a dictionary is evidence that it is acceptable in good writing. Though most dictionaries have a system of marking words as obsolete, or in use only as slang, many people, more especially if their use of a particular word has been challenged, are likely to conclude, if they find it in a dictionary, that it is accepted as being used by writers of established reputation. This would certainly have been true of dictionaries a hundred years or so ago. For a long time after they were first firmly established in the eighteenth century, their aim was to include only what was used by the best writers, and all else was suppressed, and the compiler frequently claimed that this dictionary contained "low" words. Apparently this aspect of the dictionary achieved such importance in the mind of the average person that most people today are unaware of the great change that has taken place in the compilation of present-day dictionaries. Similarly, the ordinary man invariably supposes that one dictionary is as good and authoritative as another, and, moreover, believes that "the dictionary" has absolute authority, and quotes it to clinch arguments. Although this is an advantage, in that the dictionary presents a definition the basic meaning of which can't be altered by the speaker, yet it could be accepted only if all dictionaries agreed on the particular point in question. But ultimately the authority of the dictionary rests only on the authority of the man who compiled it, and, however careful he may be, a dictionary-maker is fallible: reputable dictionaries may disagree in their judgments, and indeed different sections of the same dictionary may differ.

单选题While still in its early stages, welfare reform has already been judged a great success in many states—at least in getting people off welfare. It"s estimated that more than two million people have left the rolls since 1994. In the past four years, welfare rolls in Athens County have been cut in half. But 70 percent of the people who left in the past two years took jobs that paid less than $ 6 an hour. The result： The Athens County poverty rate still remains at more than 30 percent— twice the national average. For advocates (代言人) for the poor, that"s an indication that much more needs to be done. "More people are getting jobs, but it"s not making their lives any better," says Kathy Lairn, a policy analyst at the Center on Budget and Policy Priorities in Washington. A center analysis of U.S. Census data nationwide found that between 1995 and 1996, a greater percentage of single, female-headed households were earning money on their own, but that average income for these households actually went down. But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory. "Welfare was a poison. It was a toxin (毒素) that was poisoning the family," says Robert Rector, a welfare-reform policy analyst. "The reform is changing the moral climate in low-income communities. It"s beginning to rebuild the work ethic (工作道德), which is much more important. " Mr. Rector and others argued that once "the habit of dependency is cracked," then the country can make other policy changes aimed at improving living standards. (286 words)

单选题{{B}}Text 4{{/B}} It looked just like another aircraft from the outside. The pilot told his young passengers that it was built in 1964. But appearances were deceptive, and the 13 students from Europe and the USA who boarded the aircraft were in for the flight of their lives. Inside, the area that normally had seats had become a long white tunnel. Heavily padded(填塞) from floor to ceiling, it looked a bit strange. There were almost no windows, but lights along the padded walls illuminated it. Most of the seats had been taken out, apart from a few at the back, where the young scientists quickly took their places with a look of fear. For 12 months, science students from across the continents had competed to win a place on the flight at the invitation of the European Space Agency. The challenge had been to suggest imaginative experiments to be conducted in weightless conditions. For the next two hours, the flight resembled that of an enormous bird which had lost its reason, shooting upwards towards the heavens before rushing towards Earth. The invention was to achieve weightlessness for a few seconds. The aircraft took off smoothly enough, but any feelings that I and the young scientists had that we were on anything like a scheduled passenger service were quickly dismissed when the pilot put the plane into a 45-degree climb which lasted around 20 seconds. Then the engines cut out and we became weightless. Everything became confused and left or right, up or down no longer had any meaning. After ten seconds of free-fall descent(下降) the pilot pulled the aircraft out of its nosedive. The return of gravity was less immediate than its loss, but was still sudden enough to ensure that some students came down with a bump. Each time the pilot cut the engines and we became weightless, a new team conducted its experiment. First it was the Dutch who wanted to discover how it is that cats always land on their feet. Then the German team who conducted a successful experiment on a traditional building method to see if it could be used for building a future space station The Americans had an idea to create solar sails that could be used by satellites. After two hours of going up and down in the lane doing their experiments, the predominant feeling was one of excitement rather than sickness. Most of the students thought it was an unforgettable experience and one they would be keen to repeat.

单选题 Successful innovations have driven many older technologies to extinction and have resulted in higher productivity, greater consumption of energy, increased demand for raw materials, accelerated flow of materials through the economy and increased quantities of metals and other substances in use per person. The history of industrial development is full of examples. In 1870, homes and mules were the prime source of power on U.S. farms. One horse or many decades. At that time, had a national commission been asked to forecast the horse and mule population for 1970, its answer probably would have depended on whether its consultants were of an economic mm of mind. Had they been "economists", they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that would be only a matter of time before steam would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.
