【题目】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 65 kilometers from his office at the University of Southern California, in Los Angeles. He is always late even with the help of a navigation (导航) 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 (独特的) 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.

试题分析：本文讲述的是现在司机喜欢用导航来提前知道前方的道路状况，司机们也一样会有更好的技术在导航领域。
【1】C细节理解题。根据文章前两段的内容可知，洛杉矶的交通堵塞很严重。Professor Cyrus Shahabi经常迟到也是因为这个。故选C。
【2】A细节理解题。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况，故选A。
【3】B 词义猜测题。由本段上一句可知，在司机出发之前，这个系统会对路况进行分析。故选B。
【4】D主旨大意题。由文章最后一段可知，Professor Shahabi希望自己的发明能够得到进一步推广，对前景很乐观。故选C。
