14.In Los Angeles,drivers spend sixty-one hours every year stuck in traffic.These drivers know all
too well how bad the traffic can be."There're too many cars,and you can't move around a lot."
Professor Cyrus Shahabi also knows about traffic jams.He lives more than 65kilometers from
his office at the University of Southern California,in Los Angeles.He is always late even with thehelp of a navigation (導(dǎo)航) system.He decided to develop a program called ClearPath for that.He says his program uses historical
data to predict traffic conditions even before the driver leaves the house."What's unique (獨(dú)特的) isthat we use a lot of data that's currently become available including traffic data,weather data,and we analyze that so that we can predict what's going to happen in front of you when leave home."Professor Shahabi says his system does more than just answer current traffic conditions.With ClearPath,he says,a driver can decide what time he wants to leave,and ClearPath will give thefastest route.It looks at the entire road network,including surface streets as well as highways,before the driver hits the road.Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.
"I always thought that Los Angeles had the worst traffic,but now I know that Shanghai,Beijing,
Seoul,Tokyo,believe it or not,Singapore,Hong Kong certainly are examples that can immediately
use this."Professor Shahabi hopes to share this new technology with companies that already have
navigation systems,such as Google and Apple.

A.his living far away

C.It helps drivers see clearly what happens on the road.
D.It can use a lot of information and data all over the world.

分析 本文寫了現(xiàn)在司機(jī)喜歡用導(dǎo)航來提前知道前方的道路狀況,司機(jī)們也一樣會(huì)有更好的技術(shù)在導(dǎo)航領(lǐng)域.

解答 29.C.理解推斷題.由第一段介紹壞的交通狀況和第二段Professor Cyrus Shahabi also knows about traffic jams,可知教授深受其害,這就是他遲到的原因,故選C.
30.A.細(xì)節(jié)理解題.由第四段 Professor Shahabi says his system does more than just respond to current traffic conditions. 可知可以知道路上的情況,故選A.
31.B.詞義猜測題.由本段上一句With ClearPath,he says,a driver can decide what time he wants to leave,and ClearPath will give thefastest route這個(gè)系統(tǒng)會(huì)對(duì)路況進(jìn)行分析得出最快路線.可推知,是在司機(jī)出發(fā)之前,故選B.
32.D.寫作態(tài)度題.由文章最后一段Professor Shahabi hopes to share this new technology with companies that already have navigation systems可知,Professor Shahabi希望自己的發(fā)明能夠得到進(jìn)一步推廣,對(duì)前景很樂觀.故選D.

點(diǎn)評(píng) 在做閱讀理解時(shí),考生可快速閱讀短文,通讀測試題,明確考察點(diǎn),在對(duì)應(yīng)細(xì)讀,加快做題速度.有時(shí)間還可以復(fù)查校對(duì)答案.
