Inventors and inventions,Unit 3,Steven Spielberg's 2002 science-fiction thriller Minority Report produced a world where computers could read minds and predict the future. It seemed fanciful at the time, but fantasy is edging closer to fact. On Jan. 31, a team of scientists at UC Berkeley, led by Robert Knight programmed computers to decode (破譯) brain waves and replay them as words. Five months earlier, another group of Berkeley scientists showed their colleagues short movies and used computers to play back in color what people saw.,,These experiments are a big advance from 2006, when a French scientist first replayed images from a human mind, a black-and-white checkerboard pattern. The possibilities are great: a disabled person could “speak”； doctors could access the mind of a patient who fainted; you could rewatch your dreams on an iPad. There are, of course, equally dark side, such as the involuntary take out of information from the brain. In spite of these breakthroughs, Jack Gallant, the neuroscientist who led the first Berkeley team, says current technology for decoding brain activity is still “relatively primitive”. The field is held back by its poor machinery, in particular the fMRI.,“Eventually，” says Gallant, “someone will invent a decoding machine you can wear as a hat.” Such an advance into the human mind, he says might take 30 years. Still, the recent advances at Berkeley offer small answers, which scientists can use to begin unlocking the secrets of memory and consciousness.,語篇概述：通過科學家們的努力，驚悚科幻電影中提到的電腦能讀懂人的大腦并預測未來的幻想快要成為現(xiàn)實了。 1. What is the best title for the passage? A．New technology can read your mind B．Fantasy is edging closer to fact C．A new discovery in human brain D．The intelligent computers in the future 答案：A 標題判斷題。根據(jù)第一段并綜合全文可知，該文主要介紹了科學家利用新技術(shù)可能會讀懂人的大腦，故A項最適合作為本文的標題。,2．What did scientists at UC Berkeley do? A．They produced a fanciful world. B．They made computers jump forward like a human. C．They managed to translate brain waves into language. D．They used computers to make short movies. 答案：C 細節(jié)理解題。根據(jù)第二段第一句中的“programmed computers to decode (破譯) brain waves and replay them as words”可知，應選C。,3．Which of the following is impossible for the research? A．It can help a disabled man recover his ability of speech. B．Doctors can read a patient's mind even if he is unconscious. C．People will know what happens in their dreams. D．People's thoughts may be given away. 答案：A 推理判斷題。根據(jù)第三段的第二句“The possibilities are great: a disabled person could ‘speak’． on an iPad.”及上下文內(nèi)容可推知，該研究并不能使殘疾人恢復說話的能力，而是通過電腦讀懂殘疾人的大腦，從而使其“說話”，因此選A。,4．What plays a most important role in the development of the technology? A．A computer. B．An iPad. C．A decoding machine. D．A hat. 答案：C 細節(jié)理解題。根據(jù)倒數(shù)第三段的最后一句“The field is held back by its poor machinery, in particular the fMRI.”并結(jié)合倒數(shù)第二段的內(nèi)容可知，在該項技術(shù)的發(fā)展過程中，譯碼機起著非常重要的作用。,5．It can be inferred from the passage that ________. A．scientists got the inspiration from a movie B．the technology still has a long way to go C．the technology has been put into practice D．scientists have unlocked the secrets of memory 答案：B 推理判斷題。根據(jù)文章最后三段的內(nèi)容可知，現(xiàn)在的技術(shù)水平還處于相對原始的階段，要真正讀懂人的大腦還有很長的路要走。,
