Question

【題目】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 (導航) 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.

【3】B

【4】D

【解析】

試題分析：本文講述的是現在司機喜歡用導航來提前知道前方的道路狀況，司機們也一樣會有更好的技術在導航領域。

【1】C細節(jié)理解題。根據文章前兩段的內容可知，洛杉磯的交通堵塞很嚴重。Professor Cyrus Shahabi經常遲到也是因為這個。故選C。

【2】A細節(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。

【3】B 詞義猜測題。由本段上一句可知，在司機出發(fā)之前，這個系統(tǒng)會對路況進行分析。故選B。

【4】D主旨大意題。由文章最后一段可知，Professor Shahabi希望自己的發(fā)明能夠得到進一步推廣，對前景很樂觀。故選C。
