Question

6．People in several American states may be surprised to see cars on city streets without a driver．Experimental driverless vehicles now are legal in Florida，Nevada and California．They are pointing the way to a future that is not far down the road．The high-tech company Google has a number of self-driving cars，which had covered 480，000 kilometers by August．Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020．
     In September，California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state．"Today we're looking at science fiction becoming tomorrow's reality-the driverless car．"The technology for these cars includes cameras，radar and motion sensors．The systems have been improved through competitions sponsored by the U．S．government agency DARPA．Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races．
     Cars have become much more fuel-efficient，and new electronic features are making Hondas safer，said Angie Nucci of Honda America．"A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes．"Other safety features include warning systems on the front and the sides of the cars．Thesystems help drivers，but don't replace them．Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．
"By taking out drivers，you also remove most risks of an accident，"Kendall said．He said consumers，however，may be unwilling to lose control．"It may take them time to come to realize that the technology is indeed reliable，but it will have to prove itself first．"
     Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable．He said this will happen as the technology is improved．

Answer 1

分析 本文是一篇說(shuō)明文．文章主要介紹無(wú)人駕駛汽車已經(jīng)經(jīng)過(guò)研發(fā)階段，現(xiàn)在正在試用階段，谷歌的無(wú)人駕駛車已經(jīng)可以開(kāi)很長(zhǎng)距離．加力福利亞的州長(zhǎng)Jerry Brown 支持無(wú)人駕駛汽車上路，無(wú)人駕駛汽車上的系統(tǒng)的可以幫助人們更安全的駕駛．但Richard Mason認(rèn)為無(wú)人駕駛汽車最大的挑戰(zhàn)是它們現(xiàn)在對(duì)消費(fèi)者來(lái)說(shuō)太貴了．文章還介紹了這些汽車的系統(tǒng)設(shè)計(jì)和有待改進(jìn)的地方．在不久的將來(lái)無(wú)人駕駛汽車將不是科幻而成為現(xiàn)實(shí)．

解答 66-70  CDBAC
66．C    細(xì)節(jié)理解題．根據(jù)第一段的句子"The high-tech company Google has a number of self-driving cars，which had covered 480，000 kilometers by August．"可知，故選C．
67．D    細(xì)節(jié)理解題．根據(jù)文章第二段的句子"In September，California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state．"可知，加力福利亞的州長(zhǎng)Jerry Brown 支持無(wú)人駕駛汽車上路，故選D．
68．B   細(xì)節(jié)理解題．根據(jù)文章第三段的句子"A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes．"Other safety features include warning systems on the front and the sides of the cars．"可知，這些系統(tǒng)的作用是它們可以幫助人們更安全的駕駛，故選B．
69．A    細(xì)節(jié)理解題．根據(jù)文章最后一段的句子"Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable．"可知，Richard Mason認(rèn)為無(wú)人駕駛汽車最大的挑戰(zhàn)是它們現(xiàn)在對(duì)消費(fèi)者來(lái)說(shuō)太貴了．故選A．
70．C    主旨大意題．根據(jù)這篇文章的內(nèi)容和第一段的句子"People in several American states may be surprised to see cars on city streets without a driver．Experimental driverless vehicles now are legal in Florida，Nevada and California．They are pointing the way to a future that is not far down the road．"可知，這篇文章講的是在不久的將來(lái)無(wú)人駕駛汽車將不是科幻而成為現(xiàn)實(shí)，故選C．

點(diǎn)評(píng) 解答細(xì)節(jié)理解題時(shí)，一個(gè)常用的方法就是運(yùn)用定位法，即根據(jù)題干和選項(xiàng)中的關(guān)鍵詞從原文中找到相關(guān)的句子，與選項(xiàng)進(jìn)行比較從而確定答案；推理判斷題既要求學(xué)生透過(guò)文章表面文字信息推測(cè)文章隱含意思，又要求學(xué)生對(duì)作者的態(tài)度、意圖及文章細(xì)節(jié)的發(fā)展作正確的推理判斷，力求從作者的角度去考慮，不要固守自己的看法或觀點(diǎn)．
