12.Time Travel
If you could travel in time,where would you go?Perhaps you would watch an original performance 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 1895for 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 Wels,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 theory.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 saysyou 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 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 is 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 30million 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.

解答 28-31.ADCB
28题答案:A 考查细节推理,根据文章中的"Stories exploring the subject have been around for hundreds of years.Perhaps the best known example is science fiction novel The Time Machine"(探索这一话题的故事已经存在几百年了,或许最著名的例子就是科幻小说《时间机器》)可知此处举出《时间机器》的例子是为了说明人们早就对"时间旅行"很感兴趣了,因此本题答案为A选项;此题容易错选C选项,到目前为止还没有"时间旅行",故谈不上"时间旅行悠久的历史".
29题答案:D 考查细节推理,此段句首提到"But could time travel actually be possible?Some scientists say yes,in theory."(但是时间旅行真的可能吗?一些科学家说理论上是可能的.),后面举了爱因斯坦的相对论表明在极端环境下进行时间旅行时可能的、霍金说可以使用一个接近光速的宇宙飞船进行时间旅行;故通过爱因斯坦和霍金的理论我们可以得知时间旅行是可能的.综上,本题答案为D选项.
30题答案:C 考查细节推理,根据文章中的"It asks what would happen if a time traveler were to go back in time and have is 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?"("祖父悖论"提出一个问题:如果时间旅行者在时间隧道中回去因为某种原因把自己的祖父给杀了,这样的话他自己就无法出生了.如果时间旅行者没有出生,那他怎样可能在时间隧道中回去呢?)可知本题答案为C选项.
31题答案:B 考查细节推理,根据最后一段的"If that's what's in store,maybe we are better just living in the present day after all"(如果那样的事情会发生,或许我们最好还是活在当下吧.)可知作者对于时间旅行的态度是"怀疑的",故本题答案为B选项.
