1、【 精品教育资源文库 】 Unit 3 Computers 单元加餐练 . 阅读理解 A (2017 北京高考 )Hollywoods theory that machines with evil (邪恶的 ) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence (AI) may become extremely good at achieving something other than
2、 what we really want. In 1960 a wellknown mathematician Norbert Wiener, who founded the field of cybernetics (控制论 ), put it this way： “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere (干预 ), we had better be quite sure that the purpose put
3、into the machine is the purpose which we really desire.” A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not inborn, nor is it something introduced by humans; it is a logic
4、al consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere wi
5、th its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard. The possibility of entering into and losing such a match should concentrate the mind
6、s of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work：we have yet to invent a firewall that is secure against
7、 ordinary humans, let alone super intelligent machines. Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as i
8、t has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams yet that is not possible unless machines share the goals of humans. Others say we can just “switch them o ff” as if super intelligent machines are too stupid to think of that possibility.
9、 Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a sourc e of power in the transformation of these atoms is talking moonshine.” However, on September 12,1933, physicist Leo Szilard

A run out of human control B satisfy humans real desires C command armies of killer robots D work f
11、aster than a mathematician 答案： A 段落大意题。由第一段中的 “artificial intelligence(AI) may become extremely good at achieving something other than what we really want” 并结合本段内容可推断出，第一段主要告诉我们人工智能可能会超出人类的控制。故选 A。 2 Machines with specific purposes are associated with living things partly because they might be able
12、to _ . A prevent themselves from being destroyed B achieve their original goals independently C do anything successfully with given orders D beat humans in international chess matches 答案： A 推理判断题。由第二段第一句 “A machine with a specific purpose has another quality, one . associate with living things: a wi
13、sh to preserve its own existence.” 及该段内容可知，具有特殊用途的机器与生物有联系，部分是因为这种机器可能会防止自己被损害。故答案选 A。 3 According to some researchers， we can use firewalls to _ . A help super intelligent machines work better B be secure against evil human beings C keep machines from being harmed D avoid robots affecting the world
14、 答案： D 细节理解题。由第三段中的 “Some researchers argue that we can seal . never allowing them to affect the real world.” 可知，一些研究者认为，我们可以把这些机器封闭在一种防火墙内，用它们来解决难题，但从不允许它们影响真实世界，故选 D 项“ 避免机器人影响世界 ” 。 4 What does the author think of the safety problem of super intelligent machines? A It will disappear with the deve
15、lopment of AI. B It will get worse with human interference. C It will be solved but with difficulty. D It will stay for a decade. 答案： C 推理判断题。由最后一段首句 “Solving the safety pro blem well enough to move forward in AI seems to be possible but not easy.” 可知，作者认为，解决超级智能机器的安全问题是可能的，但并非易事。故选 C。 【 精品教育资源文库 】
16、 B Modern technology has a strong influence on many things we do. In fact, technology is shaping almost every part of our daytoday existence, including education. Ashok Goel is a professor at the Georgia Institute of Technology. Every term over 300 graduate students take his class on artificial inte
17、lligence (AI). The students never meet in person. All of the classes take place online through a website. Having hundreds of students in a class means Ashok Goel has to answer thousands of questions. He has eight teaching assistants to help him. But even that is not enough to give all the students t
18、he help they need. So, in January, he decided to try an experiment. At the start of the spring 2016 semester, he added a new member to his teaching team: Jill Watson. She was able to answer questions faster than most other teaching assistants. And she was available 24 hours a day. It was only at the
19、 end of the semester that Goels students learned Watsons secret: she was not a real person. Jill Watson is an AI computer program. Goel says only two students came close to predicting Watsons true identity. He was worried about telling his students because he thought they would not like being part o
20、f the experiment. But once they learned Watsons identity, they became very excited. “Then, you know what happened? They not only asked that question about Jill， ”“Is she an AI? Once the identity of Jill was revealed, the y also asked if I was an AI， ” he said. Goel now uses Watson in two classes, bu
21、t still doesnt tell his students which of his teaching assistants is a computer program. He hopes this technology will make it easier for teachers to create their programs to use in and outside the classroom. 篇章导读：本文是一篇记叙文。全文主要讲述了一个教授在学生问问题太多、忙不过来的时候选择使用人工智能计算机程序来辅助教学的这样一件事，告诉读者科学技术能够使教育变得更容易。 5 How

D Through the Internet. 答案： D 细节 理解题。根据文章第二段中的 “At the start of the spring 2016 semester, he added a new member to his teaching team: Jill Watson. .” 以及后面的 “Jill Watson is an AI computer program.” 可知，
23、 Goel 利用人工智能计算机程序，给学生提供帮助，为他们解答难题。故选 D。 6 Why did Goel decide to try an experiment? A Because some questions were difficult for assitants to answer. B Because it was hard to answer so many students questions. 【 精品教育资源文库 】 C Because he was too tired to answer those questions. D Because he wanted to improve students selfstudy ability. 答案： B 细节理解题。根据文章第二段中的前四句可知 ，因为有几百名学生问问题，即使有 8 名助教来帮忙，也很难应对。由此，他决定做一个实验，使用人工智能计算机程序。故选 B。 7 Whats the students response to Jill Watson?
