10.A major development to self-driving cars may change the way we will drive in the future.Google,the leading company in self-driving technology,has changed its development plan.It had driverless cars built by car factories,but now will start building its own car.Google has started to build some kinds of experimental electric self-driving cars that look like a Smart car.There is no steering wheel(方向盘),gas pedal or brake.The only thing a human passenger controls is a red"e-stop"button for fear stops and a start button.The car's only"friendly"face is designed to make it help people accept self-driving technology.
Google workers took part in a long experiment,in which they used self-driving cars for their usual travel to work.No accident happened,but Google's leaders realized that depending on a human passenger to drive in an emergency wouldn't work because they may be reading,working,or sleeping.Now the self-driving car drives by itself if the driver takes his hands off the wheel for over ten seconds.
Google's self-driving cars are now limited to a speed of 25miles per hour for safety reasons.The cars aren't allowed to drive on highways.However,a Google engineer said that once the cars are solved to run safely,we can drive at the speed of 50,even 80miles an hour.
Google recently announced that its cars had covered 700,000miles of public roads,and they were now running in busy city streets.People who love self-driving cars say this will improve transport by making roads safer,cutting down accident,and making less pollution.

分析 本文介绍了自动驾驶小车技术的现状,发展前景等.
解答 21.D,细节理解题,根据句子It had driverless cars built by car factories,but now will start building its own car可知,Google计划建造自己的自动驾驶小车,故答案为D.
22.C,段落大意题,根据第一句Google workers took part in a long experiment,in which they used self-driving cars for their usual travel to work可知,这一段主要讲的是谷歌的自动驾驶汽车,故答案为C.
23.A,细节理解题,根据句子Google's self-driving cars are now limited to a speed of 25miles per hour for safety reasons可知,为了安全谷歌的自动驾驶汽车限速为每小时25英里,故答案为A.
24.B,推理判断题,根据句子People who love self-driving cars say this will improve transport by making roads safer,cutting down accident,and making less pollution.可知,自动驾驶汽车有很多好处,以后将会有更多的自动驾驶汽车,故答案为B.
点评 解答任务型阅读理解题,首先对原文材料迅速浏览,掌握全文的主旨大意.因为阅读理解题一般没有标题,所以,速读全文,抓住中心主旨很有必要,在速读的过程中,应尽可能多地捕获信息材料.其次,细读题材,各个击破.掌握全文的大意之后,细细阅读每篇材料后的问题,弄清每题要求后,带着问题,再回到原文中去寻找、捕获有关信息.最后,要善于抓住每段的主题句,阅读时,要有较强的针对性.对于捕获到的信息,要做认真分析,仔细推敲,理解透彻,只有这样,针对题目要求,才能做到稳、准.
