【正文】 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(中子誘導(dǎo)) nuclear chain reaction. 1 mainly tells us that artificial intelligence may .A. run out of human controlB. satisfy human’s real desiresC. mand armies of killer robotsD. work faster than a mathematician with specific purposes are associated with living things partly because they might be able to .A. prevent themselves from being destroyedB achieve their original goals independentlyC. do anything successfully with given ordersD. beat humans in international chess matches to some researchers, we can use firewalls to .A. help super intelligent machines work betterB. be secure against evil human beingsC. keep machines from being harmedD. avoid robots’ affecting the world 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.第二節(jié) （共 5 小題；每小題 2 分，共 10 分） 根據(jù)短文內(nèi)容，從短文后的七個選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。 Every animal sleeps,but the reason for this has remained lab rats are not allowed to sleep,they die within a month. 71 One idea is that sleep helps us strengthen new memories. 72 We know that,while awake,fresh memories are recorded by reinforeing (加強(qiáng))connections between brain cells,but the memory processes that take place while we sleep have been unclear. Support is growing for a theory that sleep evolved so that connections between neurons（神經(jīng)元）in the brain can be weakened overnight,making room for fresh memories to from the next day. 73 Now we have the most direct evidence yet that he is right. 74 The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep,showing that the connections between neurons weaken while sleeping.If Tononi`s theory is right,it would explain why,when we miss a night`s,we find it harder the next day to concentrate and learn new informationour brains may have smaller room for new experences.Their research also suggests how we may build lasting memories over time even though the synapscs bee team discovered that some synapses seem to be protected and stayed the same size. 75 “You keep what matters,”Tononi says.A. We should also try to sleep well the night before.B. Ti’s as if the brain is preserving its most important memories.C. Similarly, when people go for a few days without sleeping, they get sick.D. The processes take place to stop our brains being loaded with memories.E. That’s why students do better in tests if they get a chance to sleep after learning.F. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.G. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.第四部分：書面表達(dá)（共兩節(jié)，35 分） 第一節(jié) （15分）你的英國朋友Jim所在的學(xué)校要組織學(xué)生來中國旅行，有兩條線路可以選擇：“長江之行”或者“泰山之旅”。Jim來信希望你能給些建議。請你給他回信，內(nèi)容包括：；；。注意：；，不計入總詞數(shù)。Dear Jim, Yours,Li Hua第二節(jié) （20 分）假設(shè)你是紅星中學(xué)高三學(xué)生李華，請根據(jù)以下四幅圖的先后順序，寫一篇英文周記，記錄畢業(yè)前夕你們制作以“感恩母?！睘橹黝}的畢業(yè)紀(jì)念視頻的全過程。注意：詞數(shù)不少于60。提示詞：視頻video2017年普通高等學(xué)校全國招生統(tǒng)一考試（北京卷）英語參考答案21.
