UNIT 1 课时跟踪检测（四） 重点题型强化练

Ⅰ.阅读理解

What if we had the power to control time, instead of moving from the past to the present to the future? What if we could jump, loop and travel through time in a machine? What if we could go wherever and whenever we pleased?

This ability would allow us to witness historic wonders, change decisions and see people from the past. We could right wrongs and stop wars breaking out once and for all.

The mysterious puzzle of time has kept people debating its nature for hundreds of years. Science fiction writers have turned it into imaginative stories. Some scientists have even attempted to explain it using math. This math tries to make the dream of time travel come true.

The gifted scientist Albert Einstein said that time and space are one thing. He called it “spacetime”. Einstein said that there are three dimensions in space: height, width and depth. A scientist named Hermann Minkowski added time as a fourth dimension.

Einstein introduced two ideas that have led to theories about the possibility of time travel. The first is relativity. The idea of relativity is that the force of gravity causes space to bend, which causes time to twist. The second idea focuses on special relativity. The idea is that a traveler moving super fast through flat spacetime will enter the future. Einstein considered time “relative” because it is measured based on where we are on Earth or in space.

Stephen Hawking is a famous scientist. He believed that a time machine would never be built. If it were possible, he thought, we would already know. If a time machine could be built, how come no one from the future has invaded us?

The first science fiction story about this theme is The Clock That Went Backward by Edward P. Mitchell, which was published in 1881.Since then, thousands of books, films and television shows linked to this theme have explored the idea of time travel, in which some tools such as phones, watches, photographs and old books take travelers backward and forward.

Will time travel ever happen? Who knows? The most important thing is to keep your eyes open and have a sense of wonder.

语篇解读：本文是一篇说明文。文章主要分析了时间旅行是否能够成为可能，并且引用了科学家阿尔伯特·爱因斯坦和斯蒂芬·霍金对于时间旅行的看法，同时也介绍了关于时间旅行的不同作品。

1．What is the purpose of the first paragraph?

A．To show time and space are connected.

B．To show people's interest in time travel.

C．To draw readers' attention to time travel.

D．To make people believe time travel is possible.

解析：选C　推理判断题。在第一段作者提到了几个假设，然后开始介绍时间旅行这一话题，由此推断，作者写第一段的目的是吸引读者对时间旅行的注意。故选C。

2．Which of the following statements could Einstein agree with?

A．Time travel is possible in the future.

B．People can't move faster than light.

C．Time travel is against scientific rules.

D．Spacetime is not a real thing in theory.

解析：选A　推理判断题。根据第五段首句可知，爱因斯坦提出了两种观点，这两种观点导致了关于时间旅行可能性的理论。由此可推知，爱因斯坦会同意A项“时间旅行在未来是可能的”的说法。

3．What is the last but one paragraph mainly about?

A．The first science fiction story.

B．Some tools used in time travel.

C．Edward P. Mitchell, the pioneer.

D．Different works about time travel.

解析：选D　段落大意题。倒数第二段的首句介绍了第一个以这个话题为主题的科幻故事，此后，出现了成千上万的探讨时间旅行的书籍、电影和电视节目，由此可知，倒数第二段的主要内容是介绍关于时间旅行的不同作品。故选D。

4．What is the writer's attitude toward time travel?

A．Cautious.　　　　 B．Approving.

C．Doubtful.  D．Hopeful.

解析：选D　推理判断题。根据最后一段中的“The most important thing is to keep your eyes open and have a sense of wonder.”可知，作者对于时间旅行的态度是充满希望的。故选D。have a sense of wonder(持有一种好奇感)是解题的关键。
