    Science Fiction
    1 Amongst the most popular books being written today are those which are usually classified as science fiction.Hundreds of titles are published every year and are read by all kinds of people.Furthermore,some of the most successful films of recent years have been based on science fiction stories.
    2 It is often thought that science fiction is a fairly new development in literature,but its ancestors can be found in books written hundreds of years ago.These books were often concerned with the presentation of some form of ideal society,a theme which is still often found in modern stories.
    3 Most of the classics of science fiction,however,have been written within the last hundred years. Books by writers such as Jules Verne and H.G.Wells,to mention just two well-known authors,have been translated into many languages.
    4 Modern science fiction writers don ' t write about men from Mars（火星）or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future worlds which are a reflection of the world which we live in now.Because of this,their writing has obvious political undertones（含义）.
    5 In an age where science fact frequently overtakes（超过）science fiction , the writers may find it difficult to keep ahead of scientific advances.Those who are sufficiently clear-sighted to see the way we are going,however,may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.

    Paragraph 3______
    A:Popularity of Science Fiction
    B:A Fairly New Development
    C:Classics of Science Fiction
    D:Difficulty in Keeping Ahead of Scientific Adventure
    E:Its Origin
    F:Themes of Modern Science Fiction

    答案：C
    解析：
    第二段第一句提到，人们常认为科幻小说是文学中的新生产物，然而在几百年前所写的书中就能发现科幻小说的踪迹了。紧接着对这些书的内容进行了简单介绍。由此可知，第二段主要讲的是科幻小说的开端。
    第三段第一句就提到“Most of the classics of science fiction …"，紧接着又以两个著名的科幻小说家的例子进行说明，可知本段主要讲的是科幻小说中的经典之作。根据线索词“clas-sics of science fiction”也可知C项正确。
    第四段主要讲的是，现代科幻小说家不再写火星人或宇宙冒险，而是写他们对科技发展等的预测或是对未来世界的设想，并且这些作品常带有政治含义。这些都是现代科幻小说的主题。
    第五段的第一句是主题句，主要表明现代科技发展迅速，甚至超越了某些科幻小说，所以作家发现很难赶在科技发展前面。根据线索词“difficult to keep ahead of scientific advances"也可知D项正确。
    由第二段第二句可知，理想社会这个主题不仅在数百年前的著作中出现过，也在现代科幻小说中出现。由此可知，这个主题是一个反复出现的主题。recurrent反复发生的，是“stilloften found”的同义转换。
    根据第三段第二句可知，Jules Verne与H.G.Wells写的科幻小说被翻译成了多国语言。由此可知，Jules Verne写的科幻小说在全世界都有人读。
    由第四段最后一句可知，现代科幻小说有明显的政治含义。implication是undertone的同义转换，有“含义，暗示”的意思。
    由第五段第一句可知，现实中的科技发展超越了某些科幻小说，以至于很多作家感到很难赶在科技发展的前面。

    In one day at a library, 64 people borrowed books. Twice as many people borrowed only a thriller as borrowed only a science fiction book. Three people borrowed a biography only and 11 people borrowed both science fiction and a thriller, but not a biography. The same number borrowed a biography and a thriller but no science fiction as borrowed one of each of the three types. Twenty-one people did not borrow a thriller. One more person borrowed a science fiction book and a biography book than borrowed a biography only.　　How many people borrowed a thriller only?
