【正文】 their wives. In fact, some young men and women moved to munal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam. In terms of numbers, the counterculture was not a very large group of people. But its influe nce spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on “overtime” work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods. In the 1970s, the feminist movement, or women’s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women’s jobs as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion. Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations. of the following best express the main idea of Paragraph 1? usually worked outside the home for wages. and women’s roles were easily exchanged in the past. ’s roles at home were more firmly fixed than women’s. and women’s roles were usually quite separated in the past. sentence best expresses the main idea of Paragraph 2? first sentence. second and the third sentences. fourth sentence. last sentence. the passage the author proposes that the counterculture___. the United States. some American values. not important in the United States. people more leisure time with their families. could be inferred from the passage that___. and women will never share the same goals. men will be willing to exchange their traditional male roles. men will be happy to share some of the household responsibilities with their wives. American households are headed by women than ever before. best title for the passage may be ___. of Feminist Movements influence in American Life and Its consequence Division of Male and Female Roles. 第二篇答案 DCBCB 第三篇 (Unit one Passage 3) Recent research has claimed that an excess of positive ions in the air can have an ill effect on people’s physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance bees disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when winds such as the Mistral, Hamsin or Sharav are blowing in certain countries. Or it can be caused by a buildup of static electricity indoors from carpets or clothing made of manmade fibres, or from TV sets, duplicators or puter display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea or even mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to e out of hibernation, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a work of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of wellbeing. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls. To increase the supply of negative ions indoors, some scientists remend the use of ionisers: small portable machines, which generate negative ions. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat. effect does exceeding positive ionization have on some people? think they are insane. feel rather badtempered and shortfussed. bee violently sick. are too tired to do anything. accordance with the passage, static electricity can be caused by___. homemade electrical goods. clothes made of natural materials. on artificial floor coverings. TV programs on a puter. high negative ion count is likely to be found___. a pound with a water pump. to a slowflowing river. in some barren mountains. a rotating water sprinkler. kind of machine can generate negative ions indoors? . . pumps. scientists believe that___. animals to anticipate earthquakes is more effective than depending on seismography. unusual behavior of animals cannot be trusted.
