3.Passage FourEqual pay for equal work is a phrase used by the American women who feel that they are looked down upon by the society. They say it is not right for women to be paid less than men for the same work.People who hold the opposite opinion(mainly men)have an answer to this. They say that men have more responsibility than women; a married man is expected to earn money to support his family and to make important decisions, and therefore it is right for men to be paid more. There are some people who hold even stronger opinion than this and are against married women working at all. When wives go out to work, they say, the home and children are given no attention to. If women are encouraged by equal pay to take full-time job, they will be unable to do the things they are supposed to. Women are best at making a comfortable home and bringing up children. They will have to give up their present position in society."This is exactly what they want to give up, "the women who disagree say. "They want to escape from the limited place which society expects them to fill, and to have freedom to choose between a job and home life, or a mixture of the two. Women have the right of equal pay and equal opportunities."These women have expressed their opinions forcefully by using the famous saying, "All men are created equal." They point out that the meaning of this sentence is "all human beings are created equal."48. The women use the phrase "equal pay for equal work" to demand that______.A. women's work shouldn't be harder than men'sB. men should be paid less than womenC. people doing harder work should earn moreD. men and women should be paid the same amount of money for the same work

  • 第4题：

    Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey.
    Certain differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills ) , while women tend to excel (擅长) at recalling information from their brain's files (helpful with language skills and remembering the locations of objects).
    Many studies have looked for a connection between sex and the amount of mental decline ( 衰退) people experience as they age, but the results have been mixed.
    Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline．Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, "so they're the ones that may not have shown such cognitive decline," said study team leader Elizabeth of the University of Warwick in England.
    People surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category (范畴) as possible in the given time, e.g．"object usually colored gray", and recalling the location of objects in a line drawing．The first two were tasks at which men usually excel; the latter were typically dominated by women.
    Within each age group studied, men and women performed better in their separate categories on average．And though performance declined with age for both genders, women showed obviously less decline than men overall.
    According to the passage, which of the following can NOT be typed into the same category?

    A.clouD.
    B.sheep
    C.trees
    D.goose

    答案：C
