1.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 is that 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 you leave home."
Professor Shahabi says his system does more than just respond to current traffic conditions.With ClearPath,he says,a driver can decide what time he wants to leave,and ClearPath will give the fastest 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.

18.Drunken driving-sometimes called America's socially accepted form of murder-has become a national epidemic (流行病).Every hour of every day about three Americans on average are killed by drunken drivers,adding up to an incredible 250,000 over the past ten years.
A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours.Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts,but the drunken killing has recently caused so many well-publicized tragedies,especially concerning young children,that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21,reversing a trend (逆转潮流) in the 1960s to reduce it to 18.After New Jersey lowered it to 18,the number of people killed by 18-20-year-old drivers more than doubled,so the state recently upped it back to 21.Reformers,however,fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop"responsible attitudes"about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests in many areas already,to a marked drop in accidents,some states are also punishing bars for serving customers too many drinks.A bar in Massachusetts was fined for serving six or more double brandies to a customer who was"obviously drunk"and later drove off the road,killing a nine-year-old boy.
As the accidents continue to occur daily in every state,some Americans are even beginning to speak well of the 13 years national ban of alcohol that began in 1919,which President Hoover called the"noble experiment".They forgot that legal prohibition didn't stop drinking,but encouraged political corruption (腐败) and organized crime.As with the booming drug trade generally,there is no easy solution.

31.What can be inferred from the fact of the traffic accidents in New Jersey?D
A.Young drivers were usually bad.
B.Drivers should not be allowed to drink.
C.Some drivers didn't surprise the legal drinking age.
D.The legal drinking age should be raised.

C.The new laws can stop heavy drinking 
D.There should be no bars to serve drinks.
34.In America,the number of people killed by drunken drivers on average isC.
A.3 per day                    
B.250,000 over the last 10 years
C.72 each day                      
D.less than 500 each week
35.Drunken driving has become a major national problem becauseB.
A.drinking is America's socially accepted habit
B.most Americans drink quite a lot
C.not many people realized the severe subsequences caused by heavy drinking
D.publicity did not pay much attention to road accidents.
