1、課時規(guī)范練7 Unit4（A） （35分鐘） I .閱讀理解A （2017 ?北京卷） Hollywood' s theory that machines with evil （牙B惡的）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 re

2、ally want. In 1960 a well-known mathematician Norbert Wiener,who founded the field of cybernetics （控制論），put it this way: "If we use,to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere 預(yù)），we had better be quite sure that the purpose put into the machine i

3、s 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 in-born,nor is it something introduced by humans;it is a logical consequence of t

4、he 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 a

5、re 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 minds of computer scien

6、tists. 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,

7、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 it has been by som

8、e AI researchers. Some argue that humans and machines can coexist as long as they work in teams一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

9、 that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, withconfidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine. v However, on September 12,1933,physicist Leo Szilard invented the neutron-

Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters, allowing people with motor neurone disease to communicate with others from a phone

14、. The GazeSpeak app combines a smartphone? s camera with artificial intelligence to recognize eye movements in real time and convert them into letters, words and sentences. For people suffering from ALS（漸凍癥）also known as motor neuronedisease, eye movement can be the only way to communicate. “Curr

15、ent eye-tracking input systems for people with ALS or other motor impairments are expensive,not robust under sunlight,and require frequent recalibration and substantial, relatively immobile setups,“ said XiaoyiZhang,a researcher at Microsoft who developed the technology. “To mitigate the drawbacks

16、. .. we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, constant, portable and easy to learn. ” The app is used by the listener by pointing their smartphone at the speaker. A chart that can be stuck to the back of the smartphone is t

17、hen used by the speaker to determine which eye movements to make in order to communication. The sticker shows four grids （網(wǎng)格）of letters, which each correspond to a different eye movement. By looking up,down, left or right,the speaker selects which grids the letters they want belong to. The artifici

18、al intelligence algorithm is then able to predict the word or sentence they are trying to say. Zhang' s research, Smartphone-Based Gaze Gesture Communication for People with Motor Disabilities, is set to be presented at the Conference on Human Factors in Computing Systems in May. 5. How does the n

19、ew smartphone app help people with ALS? A.By looking into the eyes of the sufferers. B.By connecting its camera with sufferers' appearance. C. By communicating with people directly with a camera. D. By changing eye movements into detailed written information. 6.Why did the researchers develop G
