提能二用课文句型解构高考长难句[本单元突破点——含有状语从句的复合句]
“前沿科技”这一话题在新课标中涉及的内容很多。

如医药的进步、技术的革新、计算机技术、太空旅游和探索、未来世界、机器人、航天知识、最新科研发明、科学与生活、科技与人文、网络、传媒等。

高考命题人可能在语篇材料中涉及这些话题，主要以说明文、议论文为主。

一、话题与语篇
[考题示例] (2017·北京高考阅读D)
[1]Hollywood's 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 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 into the machine is the purpose which we really desire.”
[2]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 logical 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 with 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.
[3]The possibility of entering into and losing such a match should concentrate the minds 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 ordinary humans, let alone super intelligent machines.
[4]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 it 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 off” as if super intelligent machines are too stupid to think of that possibility. 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 source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutron­induced (中子诱导) nuclear chain reaction.
67．Paragraph 1 mainly tells us that artificial intelligence may ________.
A．run out of human control
B．satisfy human's real desires
C．command armies of killer robots
D．work faster than a mathematician
68．Machines with specific purposes are associated with living things partly because they might be able 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
69．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
70．What does the author think of the safety problem of super intelligent machines?
A．It will disappear with the development 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.

(一)这样读文

[名师解题]
67．推理判断题。

选A根据第一段中的“The real problem relates to the
possibility that artificial intelligence (AI) may become extremely good at achieving something other than what we really want.”可知，人工智能可能会变得非常擅长完成目标，而这些目标可能不是人们真正想要的，所以人工智能有可能摆脱人的控制。

68．细节理解题。

选 A 根据第二段中的“A machine with a specific purpose has another quality, one that we usually associate with living things：a wish to preserve its own existence.”可知，智能机器人可能会为保护自己的存在而阻止自己被摧毁。

69．细节理解题。

选D 根据第三段中的“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.”可知，有些研究者认为可用防火墙让机器人解决难题，但不允许机器人影响真实世界。

70．推理判断题。

选C 根据第四段中的“Solving the safety problem well enough to move forward in AI seems to be possi ble but not easy.”可知，人工智能的安全问题有可能得到解决，但又困难重重。

[阅读理解系列技巧13] 利用but/however巧解阅读理解题
通过研究近几年高考阅读理解试题，我们发现but和however重现率较高，几乎每年高考阅读理解都有一些题目的答案与这两个词有关，我们应高度重视but和however，特别是其后的内容。

表示转折的but和however有很强的意义强调功能，对我们判断上下文文意、推断作者态度、猜测人物心理、理清文章层次都具有举足轻重的作用。

but和however在文中通常有以下几种作用：
1．引出作者观点，反驳but前面的观点(普遍观点)。

2．通过对比引出相反或相对的信息。

3．表明作者态度或提出作者的建议。

例如第69题，根据第三段中的第二句话“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.”可知，人们为机器人安装防火墙是了避免它影响整个真实世界，D项所述正确。

本题就是通过but一词反驳了前面的观点，引出了后面的观点。

My Magic Watch
The watch is necessary in our daily life, but its function is too simple and dull. We should create a new watch to solve more problems. So I would like to design a watch with more practical functions.
My magic watch will have a LED screen. We can get access to various information we need through the screen. When searching for some information, we can operate it by touching the screen. It can also receive sound signals. When we talk to it, it will carry out our instructions. We can even use it as a phone to call our friends. The most special thing about the magic watch is that it has a GPS, which will help the missing find their way.
In a word, if we had such a magic watch, our life would become more convenient.
