A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce(確保) bedtime. Instead, it may be that biologically(生物學(xué)上)these sleepyhead(貪睡者)students aren’t used to the early hour.
“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice---their bodies are going through a change of sleep patterns.
All of this makes the transfer(遷移)from middle school to high school---which may start one hour earlier in the morning----all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”

Car accidents happen everywhere every day and are the main cause of injury in the United States. In order to control the increasing(增長(zhǎng)) accidents, many states have passed tough laws. Also, car manufacturers(制造商) have been trying to make safer cars to save lives.
However, as there are more and more cars and drivers on the road, these safety measure (安全措施)are not enough to stop the increasing car accidents. The National Highway Traffic Safety Administration (管理部門(mén))reports that a car accident happens every 10 seconds in the United States.
Car accidents may be caused by different reasons. Some accidents are caused by driver’s tiredness and illness or drunk driving. Some may be caused by speeding or running a red light. When this happens, by the time the driver realizes what has happened, it is usually too late. As for ages, young drivers usually have enough experience while elderly drivers of react slowly. Mechanical defects (機(jī)械毛病)such as a broken brake(剎車) are another cause of car accidents. Poor road and weather conditions can also be a cause.
Talking about different causes of car accidents can help us know what precautions(預(yù)防措施) to take beforehand. We should tell our friends or family members not to drive in poor health or after drinking wine. We should tell teenager drivers to be careful with road and weather conditions and let elderly friends understand their driving limitation(局限性)。Besides, we should have our car checked regularly(規(guī)律地). The most important thing for us to remember, however, is that we should always follow the traffic rules.
1.What has the government done to try to control the increasing car accidents?
A.They try to make safer cars. B.They try to build more roads.
C.They have passed tough traffic laws. D.They make drivers have their car examined every month.
2.What does the underlined word” elderly” possibly mean?
A.Middle-aged B.Young C.Rather old D.Teenage
3.Which of the following causes is different from the other three?
A.Tiredness B.Illness C.Drinking D.a(chǎn) broken brake
4.Which has nothing to do with a driver’s age?
A.Teenager drivers. B.Not knowing the traffic rules
C.Reacting slowly D.Driving slowly.
5.In order to avoid accidents caused by mechanical defects, we should ___________.
A.not run a red light. B.drive the car when we are in good health
C.not drive when we are too old. D.have our cars examined regularly.
