    ( 二)Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of fingerprints and discovered that no exactly similar pattern is passed on from parents to children, through nobody knows why this is the case.The structure on a person’s fingers does not change with growth and is not affected by super facial injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new skin which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own fingerprints but this is a dangerous and rare step to take.Fingerprints can be made easily with printer’s ink. They can be recorded easily. With special methods, identification(辨别)can be achieved successfully within a short time. Because of the simplicity and economy of this system, fingerprints have often been used as a method of solving criminal cases. A suspected man denies a charge, but his fingerprints can prove who he is even if his appearance has been changed by age or accident.When a suspect leaves fingerprints behind at the scene of crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print in the size of a quarter of an inch square can be obtained.6. Which of the following is NOT true of fingerprints?

    A. They vary from person to person.
    B. They are easily hidden and removed.
    C. Their uniqueness is beyond explanation.
    D. They remain unchanged throughout one’s life.

    (三)In a family where the roles of men and women are not sharply separated and where many household tasks are shared to a greater or lesser extent, male superiority is hard to maintain. The pattern of sharing in tasks and in decisions makes for equality, and this in turn leads to further sharing. In such a home, the growing boy and girl learn to accept that equality more easily than did their parents and to prepare more fully for participation in a world characterized by co-operation rather than by the “battle of the sexes”.If the process goes too far and man’s role is regarded as less important and that has happened in some cases we are as badly off as before, only in reverse.It is time to reassess(重新评估)the role of the man in the American family.We are getting a little tired of “Momism”—but we don’t want to exchange it for a “Neo-popism”(新式爸爸主义). What we need, rather, is the recognition that bringing up children involves a partnership of equals. There are signs that specialists on the family are becoming more aware of the part men play and that they have decided that women should not receive all the credit nor all the blame. We have almost given up saying that a woman’s place is in to home. We are beginning, however, to analyze men’s place in the home and to insist that he does have a place in it. Nor is that place irrelevant to the healthy development of the child.11.What will the world be like in the future according to Passage One?

    A. It will be a world of male superiority.
    B. It will be a world of equality between the sexes .
    C. It will be a world with battles between the sexes.
    D. It will be a world where men and women play different roles.

    (四)The climate phenomenon known as El Nino(厄尔尼诺)seems to be on its way back, forecasters say, raising the possibility of droughts in some places and floods in others. El Nino occurs every few years, when tropical waters off the Pacific coast of South America turn warmer than normal. Warm air rises off those waters and changes the path of the major wind currents that blow around the planet. It can weaken monsoons(季风)in South and Southeast Asia. Rainy seasons in southernAfrica can turn dry. Meanwhile, East Africa and South America can get soaked.The latest official forecasts say that there are early signs that El Nino could develop into the biggest one on record. What has attracted attention is the huge body of warm water building up below the surface of the tropical Pacific. Experts say there is more energy stored up underwater now than at this point in 1997, just before the strongest El Nino on record developed. If those warm waters in the eastern Pacific make their way to the surface and stay there, it could mean a major El Nino event, extreme weather worldwide and possibly new high-temperature records.However, just having a lot of warm water below the surface now is not enough to guarantee that we're going to have a strong El Nino. The warm water could dissipate (消散). It could come to the surface but not stay. Plus, the atmosphere has been in a cooler cycle for the past several years, which many say does not favor a strong El Nino.16. What predictions do experts make about El Nino?

    A. It may develop into an unprecedented scale.
    B. It will go hand in hand with floods and droughts.
    C. It may bring disasters to the Pacific coast of South America.
    D. It will worsen the world climate warmed by carbon dioxide.
