2021高考英语一轮课外精炼题（17）答案 （通用版）

Ⅰ. 阅读理解
A
　　I just hope that our brains won’t crash(死机). Are you working on your typing skills to make you a more efficient worker? That may be all for nothing as Intel believes that we’ll be able to control our computers with our brains by 2022.
　　Intel and its research partners are studying how brain acts when it thinks. For example, scientists have found that people’s brains react in a similar manner when asked to think of a bear.
　　Through sensors(感应器)that can find this sort of brain activity, Intel thinks that it will be able to read and translate this into an input system thanks to a chip in the brain.
　　“We’re trying to prove you can do interesting things with brain waves. ”Intel research scientist Dean Pomerleau told Computerworld. “Eventually people may be willing to be, more devoted to brain implants(植入物). Imagine being able to surf the Web with the Power of your thoughts. ”
　　Even if thinking about a bear isn’t enough to show that you want to copy and paste something. Intel still thinks that there’s a future in using your brain instead of the keyboard.
　　“If we can get to the point where you can accurately find specific words, you could mentally type, ”he added. “You could compose characters or words by thinking about letters flashing on the screen or typing whole words rather than their individual characters. ”
　　While this may all sound impractical for present time, Intel thinks that it’s possible and something we’ll all want.
“I think human beings are unusually adaptive(适应的), ”said Andrew Chien, vice president of research and director of future technologies research at Intel Labs. “If you told people 20 years ago that they would be carrying computers all the time, they would have said, ‘I don’t want that. I don’t need that. ’Now you can’t get them to stop carrying devices. There are a lot of things that have to be done first but I think implanting chips into human brains is well within the scope of possibility. ”
Make good use of your favorite mouse and keyboard set-up before they’re old-fashioned.

A. nothing is impossible
B. mankind has great power

D. human beings can adapt very well
【解析】选D。细节理解题。依据文章倒数其次段首句I think human beings are unusually adaptive可知, Andrew Chien举电脑的例子是为了证明首句的观点。
4. In the last paragraph, the author probably means that　　　.

B
We don’t know how different our future will be in the year 2050. We can only try to imagine it.
At first we think about human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today—we will feel a little lonely.
Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.
Spending holiday will also be completely different. Travelling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.
We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.
Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather sanguine about our future. We should be happy and believe good things will happen.
【文章大意】本文主要猜想2050年的生活将会是怎样的。
5. Why will people probably feel a little lonely in 2050?
A. Because the number of people will become much smaller.
B. Because there will be less face-to-face communication.
C. Because people won’t like making friends with each other.
D. Because people won’t communicate with each other much often.
【解析】选B。细节理解题。依据其次段的内容可知, 在2050年, 人们主要通过电脑进行沟通, 而很少进行面对面的沟通, 人与人之间的关系也就淡薄了, 因此那时的人们会感到有点孤独。
6. The third paragraph mainly tells us　　　.
A. that computers will do all the things for human beings
B. how people will use computers to communicate with each other
C. that machines like computers and robots will help people a lot
D. how people will use robots to do the housework
【解析】选C。段落大意题。依据第三段的内容可知, 计算机和机器人等机器会给人类很大的挂念, 故选C项。
7. The underlined word“sanguine”in the last paragraph most probably means　　　.
A. disappointed　　　　　　 B. surprised
C. curious D. optimistic
【解析】选D。词义猜想题。依据文章最终一句可以猜想出作者认为我们对将来应当持乐观乐观的态度, 故选D项。
8. What does the passage mainly talk about?
A. How people will communicate in the year 2050.
B. What our life will be like in the year 2050.
C. How people will travel and spend their holidays in the year 2050.
D. What high technology will appear in the year 2050.
【解析】选B。主旨大意题。文章的第一段就是本文的中心, 即设想2050年的生活是什么样子的, 故选B项。
