托福阅读范例二：what can we do for Shanghai Expo?
托福词汇记忆法之理解记忆法
If it were possible, however, it would present some pretty knotty paradoxes... For example, what if someone or something traveled back in time and changed the ensuing future? And have you heard the one about the time traveler who dots back and forward in time and by means of various medical technologies is able to be his own father AND mother?! And besides, if time travel is possible, where are all the people from the future--surely they'd want to come and meet us poor stranded 21st century beings?
然而，如果这一切成为可能的话，那么将会出现一些非常令人困惑的逻辑混乱……比如，如果某人或某物逆时间旅行并改变随之发生的情况，那会发生什么情况呢?又比如说，你是否曾听说过这样的事情——一位时间旅行者在时间隧道中穿梭往返，利用各种医学技术使自己成为自己的父亲和母亲?还有，如果时间旅行成为可能，未来的所有人都会在哪里呢?他们肯定想来见见我们这些滞留在21世纪的可怜人。
The experiment was replicated in 1996 with advanced technology, and it was proved again--with an even bigger time difference this time. Which proves that not only is time “warp-able”, but Einstein was arguably the greatest thinker the world has ever seen. So, time is warped--and this opens up the possibility that we might be able to somehow manipulate it as a mode of travel one day. Already one scientist has published a paper in which he detailed how to build a time machine.
1996年，科学家用先进的技术重复了同样的实验，也证实了该理论，时间差距甚至更大了。这一实验不仅验证了时间的可扭曲性，还证明爱因斯坦可能是人类史上最伟大的思想家。所以说，时间是可弯曲的。这也使我们或许有朝一日有可能利用它作为某种形式进行旅行。有一位科学家已经发表了一篇论文，详细地描述如何建造一部时间机器。
