Now, we have to shave (剃光) our heads to keep them clean without the use of water.I remember there were “Saving Water” warnings in many public places, but nobody 16 (pay) attention. We believed water would last forever. Now, all the rivers and lakes are either dry (枯竭的) or polluted. Water is much 17 (expensive) than gold and diamonds.In the past, doctors suggested adults drink eight glasses of water a day. Nowadays, I am allowed half a glass only. Most people are weak and sick.When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers and how healthy people were. When he asks, “Why is there no clean water now?” I feel guilty (有罪的).

In China and even in the world Huawei is a wonder. 34 it started producing mobile phones not many years ago, it has become one of the most famous phone companies. But in 2019, Huawei faced some 35 . The US government made a law to stop its sales in America. At the same time, the US government planned to stop 36 parts and services to Huawei. They believed Huawei’s business would be hurt this way. “We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information, ” Ren Zhengfei, Huawei’s president said. “The law would have little 37 on our company. Huawei has enough ability to 38 the problems,” Ren added. In an interview several years ago, Ren Zhengfei said, “I started Huawei with only £4000 at the beginning, but now it has become a 100-billion company. 39 experience was not as romantic as you imagine. ”Facing the law of the US, Huawei is growing. Its smartphone sales around the world rose 50 percent compared with a year earlier in the first three months of 2019. So far Huawei has grown into the world’s 40 telecommunication equipment suppliers in 170 countries. It may beat Samsung as the largest smartphone maker in the near future.

Many people today believe that technology is going to help solve some of the most difficult problems we have on the earth today. New technology may solve old problems, and it may also create new ones. ________ Each has advantages and disadvantages, as these three examples.When we dream about the future, many of us think that we will be able to fly to the skies in our own personal flying cars. We could fly at 480 km per hour, avoiding traffic lights and busy roads. However, there will be problems with traffic control. 3D printing is another new technology for the future. 3D printers are already used to make life-size models of car parts, and man-made body parts, such as ears. As we move into the future, 3D printing will change the way we make things and the way we treat sick people. The disadvantage is that such a machine is very expensive.Finally, people are trying to build a robot suit. This is an electronic suit. It allows people to lift heavy things and walk a long way. It might help people walk again after an illness or an accident. However, one disadvantage at the moment is the cost.Looking ahead, it is easy to imagine a future. We’ll be able to fly to work, print out a new pair of shoes or lift a car above our heads. Although there are some problems to solve before all of this is possible, we can certainly dream of a world. In this world, technology makes people’s lives easier and safer. It can solve some of the most difficult problems we have today.根据语篇内容，选择最佳选项。42．Which might be the missing sentence in Paragraph 1?A．No technology is perfect.B．Technology causes lots of problems.C．We can’t live well without technology.43．What problems may people meet if the flying cars become popular?A．More air pollution. B．Harder traffic control. C．More traffic lights.44．What can a robot suit help people do?①Produce electricity. ②Lift heavy things. ③Walk a long way. ④Walk again after an illness.A．①②③ B．②③④ C．①③④45．What is the structure (结构) of the text? (P＝Paragraph)A． B． C．46．What does the writer think of new technology?A．He fears it. B．He doesn’t mind it. C．He looks forward to it.What does this “thing” look like to you? Is it a snail (蜗牛)? Or is it a car? Actually, it is my design for the car of the future—a snail car. The snail car doesn’t look like any of the cars that we see every day. If anything, this car is the opposite of today’s cars. For example, today’s cars are noisy and dirty, while this one is silent and clean; today’s cars have wheels, but this one does not; traditional cars use petrol (汽油) while this car will use clean energy.One more important point about the snail car is that it is easy to drive. In fact, you don’t have to worry about driving because it can take you wherever you want to go when you say it. Let’s say you need to take a shopping trip to a supermarket. All you have to do is give an instruction to the car, like “Take me to the supermarket”, and the snail car will follow your instruction and take care of your trip. And the chances are that it will take you there even faster than you think.A lot of the technology required for my snail car already exists (存在), although some may be experimental (试验性的). Today, scientists are developing new materials for the surface of roads. Fifty years from now, perhaps sooner, some new roads will store solar energy (太阳能) under the road, and the snail car will be able to use it.However, you probably won’t see a car like this on the roads anytime soon, even if you’re under 20 today. This, perhaps, is the car of the year 2100, and the car that your grandchildren or their children will probably drive.47．How does the writer show that the snail car is the opposite of today’s cars?A．By telling stories. B．By listing numbers. C．By giving examples.48．We can learn from Paragraph 3 that the snail car is _______.A．clean B．smart C．quiet49．What does the underlined word “it” in Paragraph 4 refer to?A．Solar energy. B．Clean energy. C．The surface of roads.50．What will the writer probably talk about in the following paragraph?A．What the snail car will look like in 2024.B．Why the snail car will be popular among children.C．What the world will be like when the snail car is widely used.agree, be able to, bore, science, seem, fiftieth, work, they参考答案：1．C【详解】句意：如今，很多人因为新冠肺炎疫情而放弃了出国旅游的想法。考查动词短语。come up with想出；think of考虑；give up放弃。根据“because of the Covid-19”可知是指许多人放弃了出国旅行的想法，故选C。2．C【详解】句意：——真倒霉！我们又输了。 ——振作起来! 重要的不是赢，而是参与。考查动词短语辨析。give up放弃；take the lead带头；take part参加，参与；keep the secret保守秘密。根据“Cheer up!

It might help people walk again after an illness or an accident.”可知，它可以让人们举起重物，走很长的路。它可以帮助人们在生病或事故后重新行走。故选B。45．篇章结构题。通读全文可知，文章第一段是提出观点；接着三段分别介绍三项新技术的优缺点；最后一段总结。故选C。46．推理判断题。根据“Although there are some problems to solve before all of this is possible, we can certainly dream of a world.”可知，虽然在这一切成为可能之前还有一些问题需要解决，但我们肯定可以梦想一个世界，由此推出作者很期待新技术。故选C。47．C 48．B 49．A 50．C【导语】本文是一篇说明文，介绍了未来汽车的样子。47．细节理解题。根据“this car is the opposite of today’s cars. For example, today’s cars are noisy and dirty, while this one is silent and clean; today’s cars have wheels, but this one does not; traditional cars use petrol (汽油) while this car will use clean energy.”可知， 以举例说明蜗牛车和现在的车不同。故选C。48．推理判断题。根据“One more important point about the snail car is that it is easy to drive. In fact, you don’t have to worry about driving because it can take you wherever you want to go when you say it.”可知，关于蜗牛车更重要的一点是，它很容易驾驶。事实上，你不必担心开车，因为只要你说，它可以带你去任何你想去的地方。由此可知蜗牛车是智能的，故选B。49．词义猜测题。根据“Fifty years from now, perhaps sooner, some new roads will store solar energy (太阳能) under the road, and the snail car will be able to use it.”可知，50年后，也许更早，一些新的道路将在路面下储存太阳能，蜗牛车将能够使用它。由此可知it指的是太阳能，故选A。50．推理判断题。根据最后一段可知，该段主要介绍了像蜗牛车这样的汽车，在未来什么时候人们可以使用。由此可推知下文应与未来汽车的使用有关，“当蜗牛车被广泛使用时，世界会是什么样子”可能是下文谈论的内容。故选C。
