课时提升作业(二十三)必修5Unit 3Ⅰ. 阅读理解AI just hope that our brains won‟t crash(死机).Are you working on your typing skills to makeyou a more efficient worker? That may be all fornothing as Intel believes that we‟ll be able tocontrol our computers with our brains by 2020.Intel and its research partners are studyinghow 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 andpaste 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 som ething 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 possib ility. ”Make good use of your favorite mouse and keyboard set-up before they‟re old-fashioned.【文章大意】本文主要讲了现在Intel及同伴正在研究怎样用人脑控制我们的电脑。

BWe 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 the m. 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】本文主要预测2050年的生活将会是怎样的。
