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(方向盤),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 本文介紹了自動駕駛小車技術(shù)的現(xiàn)狀,發(fā)展前景等.
解答 21.D,細(xì)節(jié)理解題,根據(jù)句子It had driverless cars built by car factories,but now will start building its own car可知,Google計劃建造自己的自動駕駛小車,故答案為D.
22.C,段落大意題,根據(jù)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,這一段主要講的是谷歌的自動駕駛汽車,故答案為C.
23.A,細(xì)節(jié)理解題,根據(jù)句子Google's self-driving cars are now limited to a speed of 25miles per hour for safety reasons可知,為了安全谷歌的自動駕駛汽車限速為每小時25英里,故答案為A.
24.B,推理判斷題,根據(jù)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,自動駕駛汽車有很多好處,以后將會有更多的自動駕駛汽車,故答案為B.
點(diǎn)評 解答任務(wù)型閱讀理解題,首先對原文材料迅速瀏覽,掌握全文的主旨大意.因?yàn)殚喿x理解題一般沒有標(biāo)題,所以,速讀全文,抓住中心主旨很有必要,在速讀的過程中,應(yīng)盡可能多地捕獲信息材料.其次,細(xì)讀題材,各個擊破.掌握全文的大意之后,細(xì)細(xì)閱讀每篇材料后的問題,弄清每題要求后,帶著問題,再回到原文中去尋找、捕獲有關(guān)信息.最后,要善于抓住每段的主題句,閱讀時,要有較強(qiáng)的針對性.對于捕獲到的信息,要做認(rèn)真分析,仔細(xì)推敲,理解透徹,只有這樣,針對題目要求,才能做到穩(wěn)、準(zhǔn).
