单选题 Among 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 in recent years have been based on science fiction stories.
It is often thought that science fiction is a fairly new development in literature, but it 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.
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. Modern science fiction writers don"t write about men from Mars 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 world which are a reflection of the world which we live in now. Because of this their writing has obviously political undertones.
In an age where science fact frequently overtakes 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.

单选题 Which of the following statements can"t prove that science fiction is very popular today?

【正确答案】 D

【答案解析】[解析] 根据文章第一段的内容可判断A、B、C项均能证明“科幻小说是最受欢迎的书籍之一”。而D项“科幻小说可以追溯到数百年前”，这是在说科幻小说的起源，并不能证明如今科幻小说很受欢迎。故选D。

单选题 In the past, science fiction was probably concerned with ______.

【正确答案】 D

【答案解析】[解析] 文章第二段第二句话“These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.”意为“这些书(科幻小说)关注呈现理想社会的一些形态，这个主题在现代的小说中也可以找到”。由这句话推断，过去的科幻小说应该注重于呈现他们根据现实社会所想象的理想的社会，故选D。

单选题 According to the passage, we know that ______.

【正确答案】 D

【答案解析】[解析] 根据文章第三段最后一句，“Because of this their writing has obviously political undertones”可知，科幻小说家的创作会有很鲜明的政治底色，故D正确。文中第二段第一句说科幻小说经常被认为是一个很新的文学形式，但是在数百年前就可以找到科幻小说，所以A项不对；根据文章第二段第一句，文中说的是“hundreds of years ago(成百上千年前)”，不是“less than a hundred years”，所以B项不对；对于C项，文章第一段说现在科幻小说很流行，并没有比较科幻小说在现在还是在过去更出名。故选D。
