Perhaps you would watch a 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 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 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 says you could travel into the future with a really fast spaceship­going 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 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. 1．The novel The Time Machine mentioned in Paragraph 2 aims to show　______　. A．the long history of time travel B．the contribution of H．G.Wells C．people's interest in time travel D．the story's different features 2．Which of the following statements is TRUE? A．The Time Machine is one of the bestselling science fiction novels. B．It was H．G.Wells who invented the term“time machine”． C．Works of literature about time travel first appeared one hundred years ago. D．There are films, comic books and dramas adapted from the novel The Time Machine. 3．Einstein's and Hawking's theories　______　. A．have similarities because both are based on experiments B．suggest the possibility of time travel C．have been proved wrong by some time travelers D．have pushed the invention of the first spaceship 4．In Paragraph 4，“grandfather paradox”probably refers to the idea that　______　. A．the reunion of the traveler and his grandfather brings happiness B．the traveler is prevented from meeting his grandfather C．the traveler goes back in time to seek for his grandfather D．the grandfather's death makes the traveler's birth impossible [语篇解读]　本文是一篇议论文，人类一直对时间旅行很感兴趣。从理论上来说，且根据一些科幻书籍以及科学家所说，时间旅行是可以的。但是，从另一个角度而言，时间旅行未必是好事。因此作者认为我们还是生活在现在的好。 1．C　[考查推理判断。根据第二段中的“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...”时间旅行的可能性确实很吸引人。探索这个主题的故事已经有几百年了。小说The Time Machine就是一个例子。可推知，在第二段中提到The Time Machine这部小说就是想表明人们对时间旅行的兴趣。故选C。] 2．B　[考查细节理解。根据第二段中的“The term‘time machine’， coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.”“时间机器”这个术语，由Wells创造，现在被普遍用于指把人们运送到遥远的未来。可知，是H.G.Wells发明了“时间机器”这个术语。故选B。] 3．B　[考查细节理解。根据第三段中的“But could time travel actually be possible？”但是时间旅行实际上是可能的吗？，接下来举了爱因斯坦和霍金的例子“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”爱因斯坦的相对论使得在极端情况下可以进行时间旅行。英国物理学家斯蒂芬霍金说，你可以用一艘非常快的宇宙飞船以接近光速的速度旅行到未来。由此可知，霍金和爱因斯坦的理论表明了时间旅行的可能性。故选B。] 4．D　[考查细节理解。根据第四段中的“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？”可知，“grandfather paradox”提出一个问题：如果一个时间旅行者回到过去，他的祖父由于某种原因死亡，那么时间旅行者就无法出生。如果时间旅行者没有出生，他怎么会回到过去？故选D。] Ⅱ.阅读七选五 The jobs of the future have not yet been invented. 　____1____　 By helping them develop classic skills that will serve them well no matter what the future holds. Curiosity Your children need to be deeply curious. 　____2____　 Ask kids，“What ingredients (配料) can we add to make these pancakes even better next time？”and then try them out. Did those ingredients make the pancakes better? What could we try next time? Creativity True creativity is the ability to take something existing and create something new from it. 　____3____　 There are a dozen different things you can do with them. Experimenting with materials to create something new can go a long way in helping them develop their creativity. Interpersonal Skills Understanding how others feel can be a challenge for kids. We know what's going on inside our own head, but what about others? Being able to read people helps kids from misreading a situation and jumping to false conclusions. 　____4____　“Why do you think she's crying？”“Can you tell how that man is feeling by looking at his face? If someone were to do that to you, how would you feel？” Self­expression 　____5____　 There are many ways to express thoughts and ideas — music, acting, drawing, building, photography. You may find that your child is attracted by one more than another. A．Encourage kids to cook with you. B．And we can't forget science education. C．We can give kids chances to think about materials in new ways. D．So how can we help our kids prepare for jobs that don't yet exist? E．Gardening is another great activity for helping kids develop this skill. F．We can do this in real life or ask questions about characters in stories. G．Being able to communicate ideas in a meaningful way is a valuable skill. [语篇解读]　本文是一篇说明文，就如何让孩子适应未来的工作，提出了四个方面的建议：在生活和学习中培养好奇心、创造力、人际交往技巧和自我表达。 1．D　[考查对上下文的理解和推理判断能力。根据空后“By helping them develop classic skills that will serve them well no matter what the future holds.”可知，这里叙述的是帮助他们发展最优秀的技能，所以上句应该是怎样帮助为了他们未来的工作而做好准备。D.So how can we help our kids prepare for jobs that don't yet exist？“我们怎样才能帮助孩子们准备那些还不存在的工作呢？”符合语境。故选D。] 2．A　[考查对上下文的理解和推理判断能力。根据空后“Ask kids，‘What ingredients (配料) can we add to make these pancakes even better next time？’and then try them out.”可知，下文叙述的是做煎饼时添加什么配料会更好，所以上句应该鼓励孩子和你一起做饭。A.Encourage kids to cook with you.“鼓励孩子们和你一起做饭”符合语境。故选A。] 3．C　[考查对上下文的理解和推理判断能力。根据空前“True creativity is the ability to take something existing and create something new from it.”可知，上文叙述的是培养孩子的创造力，给他们一些材料，然后从这些材料中创造出新的东西。所以下文应该是我们给孩子提供机会用新的方式来使用这些材料。C.We can give kids chances to think about materials in new ways.“我们可以给孩子们以新的方式思考使用材料的机会”，符合语境。故选C。] 4．F　[考查对上下文的理解和推理判断能力。根据空后“‘Why do you think she's crying？’‘Can you tell how that man is feeling by looking at his face? If someone were to do that to you, how would you feel？’”可知，此处是问孩子怎样判断人的情感问题，所以上句应该是我们在真实生活中的做法以及问一些故事中有关人物的问题。F.We can do this in real life or ask questions about characters in stories.“我们可以在现实生活中这样做，也可以问一些关于故事中人物的问题”符合语境。故选F。] 5．G　[考查对上下文的理解和推理判断能力。根据空后“There are many ways to express thoughts and ideas — music, acting, drawing, building, photography. You may find that your child is attracted by one more than another.”可知，有许多方法表达出自己的想法和观点，所以用一种有效的方式交流是一种技能。G.Being able to communicate ideas in a meaningful way is a valuable skill.“能够以有意义的方式交流思想是一项宝贵的技能”符合语境。故选G。] Ⅲ.语法填空 Everyone 　____1____　 (complain) about being stuck in traffic. It is quite possible that the future city will have no traffic at all. H．G Wells, in his book The Sleeper Awakes, tells something about the traffic. In the streets of that future London there will be no vehicles. The city 　_____2_____　 (provide) with moving roads. One side of the road travels 　____3____　 one direction; the other side moves 　____4____　 opposite way. Anyone who wants to go to another part of the city steps on the moving“way”and sits on one of the seats until he arrives. He has none of the troubles 　_____5_____　 a private car brings with it: whether there is enough petrol, whether the tyres are all right, where to park it. The moving way is always at his service, always moving 　____6____　 (silent) along, always ready 　____7____　 (take) him to his destination. That city of the future has no traffic jams. To link up the 　____8____　 (vary) cities, vehicles driven by atomic power will pass along highways 　____9____　 (divide) into two main groups of lanes. Each group will consist of several lanes, some for slow traffic, some for fast. Crossroads will not exist on these highways, but will be replaced by bridges and junctions(交叉口). Where these highways enter 　____10____　 (city), ports and other built­up areas, they will pass through underground tunnels. [语篇解读]　每个人都抱怨交通堵塞，本文讲述了H.G Wells这个人预言的未来交通。 1．complains　[句意：每个人都抱怨交通堵塞。根据句意可知，用一般现在时态，Everyone作主语，谓语动词用单数，故填complains。] 2．will be provided　[句意：这个城市将被提供移动公路。根据句意可知，用一般将来时态的被动语态，故填will be provided。] 3．in　[固定形式：in the direction在某个方向。故填in。] 4．the　[表示“另一方移动相反的方向”。此处表示特指，故填the。] 5．which/that　[none of the troubles作先行词，指物，后面是定语从句，在从句中作宾语，故填which/that。] 6．silently　[副词修饰动词，故填silently。] 7．to take　[固定词组：be ready to do sth.准备做某事，故填to take。] 8．various　[形容词修饰名词，故填various。] 9．divided　[表示“被分成两条主要车道的高速公路”，过去分词作后置定语，故填divided。] 10．cities　[句意：高速进入城市的地方，也就是港口和其他建筑物多的地方。不只是一个城市，故此处用名词复数，故填cities。] 学科网（北京）股份有限公司 $
