Question

【题目】Time Travel

If you could travel in time, where would you go? Perhaps you would watch an originalperformance of a Shakespeare’s play in Elizabethan England?

What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you’d voyage far ahead of the present day to see what the future holds.

The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is science fiction novel The Time Machine, which was written by H.G.Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term “time machine”, coined by

Wells, is now universally used to refer to a vehicle transporting people into the far future.

But could time travel actually be possible? Some scientists say yes, in theroy. They propose using cracks in time and space called“wormholes”,which could be used as shortcuts to other periods．Einstein's theory of relativity allows time travel in extreme circumstances．And British physicist Stephen Hawking says you could travel into the future with a really fast spaceship—going at nearly the speed of light．Though building such a spaceship would of course be no simple task．

Even if/span> you could travel into the past, there is something called the “grandfather paradox”．It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born．If the time traveler wasn't born, how would he travel back in time？

And would you really like to visit the future？In H．G．Wells' book,the main character travels into distant time where he arrives at a beach and is attacked by giant crabs．He then voyages 30 million years into the future where the only living thing is a black object with tentacles（触角）.

If that's what's in store, maybe we are better just living in the present day after all．

【2】Einstein's and Hawking's theories_________．

【3】In Paragraph 4,“grandfather paradox”probably refers to the idea that__________．

A．the traveler is prevented from meeting his grandfather

B．the traveler goes back in time to seek for his grandfather

C．the grandfather's death makes the traveler's birth impossible

D．The reunion of the traveler and his grandfather brings happiness

【4】According to the passage, what is probably the author's attitude towards time travel？

A．Unclear． B．Skeptical．

C．Supportive．D．Unconcerned．

【解析】

试题分析: 本文提到对于时光穿梭的理论的解释及他的可行性

【1】A 考查细节理解题。第二段提到The possibility of time travel is indeed appealing时光穿梭的可能是的确是很吸引人，故选A项。

【2】D 考查细节理解题。根据第三段提到Einstein's theory of relativity allows time travel in extreme circumstances．And British physicist Stephen Hawking says you could travel into the future with a really fast spaceship—going at nearly the speed of light．可知爱迪生的相对论允许在时光穿梭在特定的环境下，英国物理学家斯蒂芬·霍金说你可以用快速的宇宙飞船到未来旅行，可知两个人的理论有共同之处 ，故选D项。

【3】C 考查推理判断题。根据第四段提到It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born如果时光穿梭者按时回来，他的祖父因为某种原因而被杀死，会发生什么样子，因此阻止自己重生，故选C项。

【4】B 考查推理判断题。根据最后一段提到If that's what's in store, maybe we are better just living in the present day after all如果这样的事情发生，我们还是最后活在现在比较好，所以对时光穿梭是怀疑的态度，故选B项。
