Since the late 1960s a growing number of women have expressed a strong dissatisfaction with any marriage arrangement wherein the husband and his career are the primary considerations in the marriage.By the end of the 1970s, for example, considerably less than half of the women in the United States still believed that they would put their husbands and children ahead of their own careers.More and more American women have come to believe that they should be equal partners rather than junior partners in their marriages.This stage of marriage, although not typical of most American marriages at present, will grow most rapidly in the future.In an equal partnership marriage, the wife pursues a full time job or career which has equal importance to her husband's.The long-standing division of labor between husband and wife comes to an end.The husband is no longer the main provider of

family income, and the wife no longer has the main responsibilities for household duties and raising children.Husband and wife share all these duties equally.Power over family decisions is also shared equally.The rapid change in women's attitudes toward marriage in 1970s reflected rapid change in the larger society.The women's Liberation movement appeared in the late 1960s, demanding an end to all forms of sexual discrimination against females.An Equal Rights Amendment(修正案)to the U.S.Constitution was proposed which would make any form of discrimination on the basis of sex illegal, and though it has failed to be ratified, it continues to have millions of supporters.1． Since the late 1960s, more and more women dissatisfied with the marriage ________.A． arranged by other people B． in which husband and children are put in the first place C． in which they themselves have superior privilege D． arranged by their husbands 2． In an equal partnership marriage, ________.A． the wife is the main provider of family income B． the wife no longer has household duty C． the husband and wife share the responsibility for the family D． the husband and wife will not quarrel in the family 3． The Women's Liberation Movement ________.A． maintains sexual equality

B． claims to get rid of family responsibility C． began in the end of 1970s D． thinks that husband and wife should interchange roles in family 4． The word “ratified”(the forth line in paragraph 3)probably means ________.A． encouraged B． objected

C． disproved D． confirmed

5． In 1970s, women's attitude toward marriage changed rapidly because ________.A． women's liberation movement appeared in the late 1960s B． an Equal Rights Amendment to the U.S.Constitution was proposed C． husband is no longer the main provider of family income D． both A and B 2．（編輯：白天驕）

The skin which covers the tips of the fingers and thumbs is crossed by numerous ridges(隆 起)arranged in different patterns.This patterns are permanent from birth and remain exactly the same throughout a person's life, even when the skin becomes wrinkled and cracked as a result of old age.Such patterns are never passed on from parents to children, and no one in the world has the same patterns as anyone else.Even identical twins have different sets of fingerprints.As a result, fingerprints offer a most useful and foolproof way of identifying people.Any ridged part of the hand and the foot may be used as a means of identification, but finger impressions are usually preferred since they can be taken easily and quickly.Fingerprints are classified in the ways: by general shapes and contours, by the finger positions of the pattern-types, and by size(often measured by counting the ridges in the loops).Every set of fingerprints has different “ridge characteristics”(i.e.the print of each separate finger is different from that of all the other fingers), which belong to one of four basic groups: arches, loops, whorls and composites.All fingerprints can then be divided into 1, 024 groups.By using details in the patterns above, these 1, 024 groups can be further divided into thousands of smaller groups, thus making it possible to find a particular see prints in a few minutes.1． According to this passage, the true statement about human fingerprints is that ________.A． people's fingerprints can be inherited B． people's fingerprints are unique but identical twins may have the same fingerprints C． using fingerprints is the only way to identify people D． people's fingerprints will not change in all their lives

2． We prefer to use fingerprints to identify people because ________.A． we can never find the same set of fingerprints among human beings

4． The word“foolproof”(line 7, pare.1)most probably means ________.A． that is permanent B． that is helpful C． that is not foolish D． that can not go wrong 5． The passage is most probably taken from an article entitled ________.A． Permanent Fingerprints B． Classification of Fingerprints C． Ridge Characteristics D． A Means of Identification 3．（編輯：白天驕）

When a consumer finds that an item she or he bought is faulty or in some other way doesn't live up to the manufacture's claim for it, the first step is to present the warranty(保單), or any other records which might help, at the store of purchase.In most cases, this action will produce results.However, if it does not, there are various means the consumer may use to gain satisfaction.A simple and common method used by many consumers is to complain directly to the store manager.In general, the “higher up”the consumer takes his or her complaint, the faster he or she can expect it to be settled.In such a case, it is usually settled in the consumer's favour, assuring he or she has a just claim.Consumers should complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter.Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question.If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements.For example, “The left speaker does not work at all and the sound coming out of the right one is unclear”is better than“This stereo(立體聲音響)does not work.”

1． The possible meaning of the phrase“l(fā)ive up to”(line 2, para.1)may be ________.A． to make up to consumers B． to keep to the high standards of C． to be the best compared with others D． to stand for salesmen's benefits 2． If a consumer finds what she or he bought doesn't live up to the manufacture's claim for it, ________.A． presenting the warranty is the only way to settle the problem B． there are many ways for the consumer to gain satisfaction C． the first thing to do is to threaten to take the matter to court D． what she or he should do is to keep silent 3． If a consumer complain in person to the store manager，__________.A． it's possible to settle the problem in the consumer's favour B． the consumer can surely get the compensation C． the salesgirl is surely scolded by the manager D． the consumer is surely refused 4． The most effective complaint can be made ________.A． in a firm and exaggerated way B． by presenting specific information as to what is wrong C． by making general statements

D． by complaining to the manager loudy and firmly 5． the main idea in this passage is about ________.A． salesmen's strategies to satisfy consumers B． consumers' strategies to get the most from the store C． how to buy satisfactory goods D． how to protect consumers' rights

七、英譯漢題

1． Organization also makes a difference in our ability to remember.How useful would a library be if the books were kept in random order? Material that is organized is better remembered than jumbled information.One example of organization is chunking.Chunking consists of grouping separate bits of information.For example, the number 4671363 is more easily remembered if it is chunked as 467,13,63.Categorizing is another means of organization.Suppose you are asked to remember the following list of

words: man, bench, dog, desk, woman, horse, child, cat chair.Many people will group the words into similar categories and remember them as follows: man, woman, child;cat, dog, horse;bench, chair, desk.Needless to say, the second list can be remembered more easily than the first one.
