A recent study, published in last week's Journal of the American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal accident as a teenager driving alone. By contrast, the risk of death for drivers between 30 and 59 decreases with each additional passenger, The authors also found that the death rates for teenage drivers increased dramatically after 10 p.m., and especially after midnight. With passengers in the car, the driver was even more likely to die in a late-night accident.
Robert Foss, a scientist at the Highway Safety Research Center of University of North Carolina, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving experience. "The basic issue" he says, "is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is."
Both he and the author of the study believe that the way to mitigate (使……缓解)the problem is to have states institute so-called graduated licensing systems, in which getting a license is a multistage process. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving with night of passenger restrictions, before graduating to full driving privileges.
Graduated licensing systems have reduced teenage driver crashes, according to recent studies. About half of the states now have some sort of graduated licensing system in place, but only 10 of those states have restrictions on passengers. California is the strictest, with a novice(新手) driver prohibited from carrying any passenger under 20(without the presence of an adult over 25)for the first six months.

听力原文： One kind of vacation that many Americans enjoy is camping. Each summer millions of Americans drive to the countryside where they find places to camp. The national parks, many of which are in the mountains, are favorite camping places. Campers enjoy the fresh air, the lakes and the forests which they find in these parks. Campers hike, swim and fish. They can also find many kinds of animals and plants in the parks. Mostly, campers relax. They enjoy a change from their busy lives in the city. Some campers have trailers which they drive or pull behind their cars to their camp sites. Trailers are like houses on wheeks. They have many conveniences which people have in their homes, such as electricity and hot water. But most campers don't have trailers. They camp in tents which they set up in their camp sites. Campers in tents don't have the conveniences that campers in trailers have. Tent campers enjoy a very simple life.
