每日一练，专升本英语阅读理解练习(2.2)

　　Futurist Ian Pearson sees a convergence(会聚区) between clever computers and biotechnology, the coming of implanted chips and enhanced mental ability. Both machines and humans will have access to a global net with instant access to the world's knowledge. But Pearson also fears that it could divide the world into two classes—those with access to this knowledge and those without. Clearly, there is a risk of losing control of things which are capable of thinking. Pearson expects machines to be as smart as humans by 2050. After that, computers will continue to get even smarter.

　　The trouble with the digital revolution, says MIT Media Lab director Neil Gershenfeld in his book When Things Start to Think, is that computers may have speeded up many of the processes of modern life, but they still remain relatively difficult to use. “Most computers are nearly blind, deaf and dumb,” says Gershenfeld. The speed of the computer is increasingly much less of a concern than the difficulty：

　　1. in telling it what you want it to do, or

　　2. in understanding what it has done, or

　　3. in using it where you want to go, rather than where it can go.

　　What's needed now, he concludes, is digital evolution. The real challenge is how to create systems with many parts that can work together and change, combining the physical world with the digital world.

　　If we can manage the development so that they(thinking machines) stay our friends, in just a few years we'll see progress in every area of life that makes the past centuries look like all of us had been asleep.

　　“Evolution is a result of interaction,” says Gershenfeld. “And information technology is greatly changing how we interact. Therefore, it's not crazy to think about the influence of this on evolution.”

　　问题：

　　1.What is the main idea of this passage?

　　A.Computers will become smarter and smarter.

　　B.The image of things will be different in the future.

　　C.The speed of computers is much less of a concern.

　　D.Computers will divide the world into two classes.

　　【参考答案】A

　　[考点]主旨大意题

　　【精析】A 通读全文可知，文章主要介绍了计算机的未来发展趋势，即它将变得越来越智能。故选A。

　　2.According to Pearson, are the two classes into which the world will be divided.

　　A.those who study computers in their spare time and those who don't

　　B.those who have computers to sell and those who don't

　　C.those who can use computers to learn knowledge and those who can't

　　D.those who are smarter than computers and those who aren't

　　【参考答案】C

　　[考点]事实细节题

　　【精析】C 根据第一段第三句“But Pearson also fears that it could divide the world into two classes—those with access to this knowledge and those without.”可知，世界将来可能会被划分为两类：一类是有机会使用电脑获得知识的人，另一类是不能使用电脑获得知识的人。故选C。

　　3.According to Neil Gershenfeld, is needed now.

　　A.the greater speed of computer development and the process of life

　　B.the digital evolution that combines the physical world and the digital one

　　C.the teaching computer to communicate and be friends with man

　　D.the teaching computer to speak, listen and see

　　【参考答案】B

　　[考点]事实细节题

　　【精析】B 根据倒数第三段可知，Neil Gershenfeld认为，现在需要的是将物质世界与数字世界结合起来的数字进化。故选B。

　　4. What does the underlined sentence “in just a few years we'll see progress in every area of life that makes the past centuries look like all of us had been asleep” suggest?

　　A.We have been sleeping for thousands of years according to computers.

　　B.The digital evolution has progressed very slowly during the last few years.

　　C.Comparatively speaking, progress of the past centuries was really very slow.

　　D.We can work for a few years to make progress in the digital evolution possible.

　　【参考答案】C

　　[考点]推理判断题

　　【精析】C 根据倒数第二段可知，如果我们能够应对发展，使思维机器继续做我们的朋友，那么在短短几年内，我们将看到生活各个领域的进步，这使过去几个世纪看起来就像我们所有人都睡着了一样。根据倒数第二段中的asleep并结合常识可推知，画线部分的言下之意是，相比于未来的进步，人类在过去的几个世纪发展太慢。故选C。

　　5. What leads to evolution according to the passage?

　　A.Information.

　　B.Revolution.

　　C.Computers.

　　D.Interaction.

　　【参考答案】D

　　[考点]事实细节题

　　【精析】D 根据最后一段第一句“‘Evolution is a result of interaction,’ says Gershenfeld.”可知，进化是相互作用的结果。故选D。
