  • 第1题:

    It can be inferred from the last paragraph that _____.

    [A] the dream to build interplanetary Internet can be fulfilled in the future

    [B] interplanetary Internet will be commercialized in 100 years

    [C] the research of Internet took 50 years

    [D] it will take a long time to build interplanetary Internet


    正确答案:A

    本题考查考生的推理引申能力。文章最后一段所做的假设(在今后50年内仅仅是研究项目的东西,在100年后完全有可能商业化)以及与因特网发展历程的比较,都是塞尔夫为了说明建立星际因特网在未来是有可能实现的,所以[A]项正确。文中提到100年只是一种假设,[B]项将其确定为商业化实现的时间,不正确。同样,[C]项将假设中的50年确定为因特网的研究年限,也不正确。该段中塞尔夫的一番话表达了他对星际因特网的建立怀有比较乐观的态度,而不是说明它需要花很长时间才能实现,[D]项不正确。

    The State of Marriage Today

    Is there something seriously wrong with marriage today?During the past 50 years,the rate of divorce in
    the United States has exploded:almost 50% of marriages end in divorce now,and the evidence suggests it is
    going to get worse.If this trend continues,it will lead to the breakup of the family,according to a spokesper-
    son for the National Family Association.Some futurists predict that in 100 years,the average American will
    marry at least four times ,and extramarital(婚外的)affairs will be even more common than they are now.
    But what are the reasons for this ,and is the picture really so gloomy(阴暗的)?The answer to the first
    question is really quite simple:marriage is no longer the necessity it once was.The institution of marriage has
    been based for years partly on economic need.Women used to be economically dependent on their
    husbands一as they usually didn't have jobs outside the home.But with the rising number of women in well-
    paying jobs,this is no longer the case,so they don't feel that they need to stay in a failing marriage.
    In answer to the second question , the outlook may not be as pessimistic(悲观的)as it seems. While the
    rate of divorce has risen;the rate of couples marrying has never actually fallen very much,so marriage is still
    quite popular. In addition to this,many couples now simply live together and don't bother to marry. These
    couples are effectively married,but they do not appear in either the marriage or divorce statistics.In fact,
    more than 50%of first marriages survive.
    So is marriage really an outdated institution?The fact that most people still get married indicates that it
    isn't. And it is also true that married couples have a healthier life than single people:they suffer less from
    stress and its consequences,such as heart problems,and married men generally consider themselves more
    contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and
    apply it to all of our relationships!

    Why is the outlook of marriage not as hopeless as it appears?
    A:Many people still like to get married.
    B:The rate of divorce has actually decreased.
    C:Over 60%of the marriages continue to exist.
    D:The statistics of divorce is reliable.

    答案:A
    解析:
    由第一段可知如果离婚率持续走高的话,会导致家庭的破裂,A项错;几乎是一半人离 婚了,而不是超过一半,故B项错;是将会结四次婚,而不是现在就结四次婚,故C项错。由段中的“it is going to get worse”可知选D。
    由第二段可知,现在妇女都有报酬好的工作了,经济都已经独立了,经济问题对于她们来说已不是问题了。故选A。
    由第三段中的“marriage is still quite popular”可知,情况还没有那么糟糕,还是有很多人 愿意结婚的。故选A。
    由第四段中的“consider themselves more contented than...”可知选D。 contented意为“满 意的”。
    文中根本没有提到出国的事,故选D。
