1、Inventors and inventions,Unit 3,Steven Spielbergs 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 Rober

2、t 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 sci

3、entist 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 i

4、nvoluntary 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 f

5、MRI.,“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 conscio

6、usness.,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? ANew technology can read your mind BFantasy is edging closer to fact CA new discovery in human brain DThe 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

7、本文的标题。,2What did scientists at UC Berkeley do? AThey produced a fanciful world. BThey made computers jump forward like a human. CThey managed to translate brain waves into language. DThey 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 re

8、play them as words”可知，应选C。,3Which of the following is impossible for the research? AIt can help a disabled man recover his ability of speech. BDoctors can read a patients mind even if he is unconscious. CPeople will know what happens in their dreams. DPeoples thoughts may be given away. 答案：A推理判断题。根据

9、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。,4What plays a most important role in the development of the technology? AA computer. BAn iPad. CA decoding machine. DA 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。,5It can be inferred from the passage that _. Ascientists got the inspiration from a movie Bthe technology still has a long way to g
