2.Even as Google plans to test its fleet(車隊)of self-driving cars on public roads this summer,its business model remains a bit of a mystery.By 2025,as many as 250,000self-driving vehicles could be sold each year globally,according to a study by an industry research firm.
"Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people,"said Chris Urmson,director of Google's self-driving car project.For now,Google has no plans to sell any of its self-driving cars.They are strictly for research.But they willhit public roads this summer near Google's headquarters in Mountain View,California.Previous testing has taken place only on closed courses.
The cars are built to operate without a steering wheel,accelerator(油門)or brake pedal."Our software and sensors do all the work,"Urmson said."The vehicles will be very basic-we want to learn from them and adapt them as quickly as possible-but they will take you where you want to go at the push of a button."The prototype(雛形)are the first of a 100-car flet the tech giant is building.
In the long run,Urmson sees a future of safer roads-the majority of auto accidents are caused by human error-and fewer traffic jams.Robotic cars could also shuttle people who can't drive because of age or illness.
Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own.The company has already tested other types of self-driving cars on public streets,including modified Lexus sport-utility vehicles,under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.
The state has ssued six other companies permits to operate such cars,including Delphi,Mercedes-Benz,Volkswagen,Tesla,Bosch and Nissan.The vehicles that will be tested on open roads this summer will have removable steering wheels,accelerators and brake pedals to allow"safety drivers"to take control if needed.
Google says the cars are safe.The vehicles have sensors that"can detect objects out to a distance of more than two football fields in all directions,which is especially helpful on busy streets with lots of intersections,"Urmson said."We're looking forward to learning how the community understands and interacts with the vehicles,and to uncovering challenges that are unique to a fully self-driving vehicle,"Urmson said.

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了Google開發(fā)的自動駕駛汽車,它使用控制軟件和感應器讓汽車能從較遠的距離感應到物體的移動,還能控制車速以確保交通安全.并且這種新型汽車已經(jīng)通過了考驗,未來很快就將被投入使用.
解答 28.A.細節(jié)理解題.根據(jù)文章第四段"In the long run,Urmson sees a future of safer roads-the majority of auto accidents are caused by human error-and fewer traffic jams"Urmson遇見了將來的道路會更加安全,因為大多數(shù)交通事故是由于人為錯誤或交通堵塞造成的,可知使用自動駕駛汽車可以減少交通堵塞;故選A.
29.A.細節(jié)理解題.根據(jù)文章第三段"The cars are built to operate without a steering wheel,accelerator(油門)or brake pedal."Our software and sensors do all the work,"Urmson said"Urmson認為他們的軟件和傳感器做了所有的工作,可知自動駕駛汽車的軟件和傳感器是至關(guān)重要的;故選A.
30.C.詞義推斷題.根據(jù)文章最后一段"The vehicles have sensors that"can detect objects out to a distance of more than two football fields in all directions,which is especially helpful on busy streets with lots of intersections"可知這種車輛的傳感器,可以檢測很遠距離之外的物體,這一點對于有很多交叉路口的繁忙街道特別有幫助,因此可推測intersections是指十字路口;故選C.
31.D.主旨大意題,通讀全文,文章主要向我們描述了Google開發(fā)的自動駕駛汽車,它使用控制軟件和感應器讓汽車能從較遠的距離感應到物體的移動,還能控制車速以確保交通安全.并且這種新型汽車已經(jīng)通過了考驗,未來很快就將被投入使用;因此可推測最合適的標題是.Google的自駕車即將被應用于城市街道;故選D.
