Inventors and inventions Unit 3话话 题题 导导 入入•Steven Spielberg's 2002 science­fiction 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 (破译) 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 black­and­white 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.•语篇概述：通过科学家们的努力，惊悚科幻电影中提到的电脑能读懂人的大脑并预测未来的幻想快要成为现实了。

•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　标题判断题根据第一段并综合全文可知，该文主要介绍了科学家利用新技术可能会读懂人的大脑，故A项最适合作为本文的标题•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　细节理解题根据第二段第一句中的“programmed computers to decode (破译) brain waves and replay them as words”可知，应选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　推理判断题根据第三段的第二句“The possibilities are great: a disabled person could ‘speak’．.. on an iPad.”及上下文内容可推知，该研究并不能使残疾人恢复说话的能力，而是通过电脑读懂残疾人的大脑，从而使其“说话”，因此选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　细节理解题。

根据倒数第三段的最后一句“The field is held back by its poor machinery, in particular the fMRI.”并结合倒数第二段的内容可知，在该项技术的发展过程中，译码机起着非常重要的作用•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　推理判断题根据文章最后三段的内容可知，现在的技术水平还处于相对原始的阶段，要真正读懂人的大脑还有很长的路要走。
