The research-- published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research-- after comparing people of normal weight- a body mass index of less than 25- with those who were overweight or obese , found that sleeping for an extra 20 minutes each night could offer a pain-free way to lose weight. Insufficient sleep is linked with changes in hormone levels that may stimulateappetite. A series of studies in recent months have shown that the less people sleep, the heavier they tend to be. American researcher Robert Vorona from Eastern Virginia Medical School in Norfolk and colleagues have now examined the relationship between people's self-reported sleep time per 24 hours and their body mass index(BMI). They found that total sleep time and BMI were inversely correlated was total sleep time decreased, BMI increased, except in the severely obese group." Americans experience insufficient sleep and corpulent bodies. Clinicians are aware of the burden of obesity on patients," the study said. "Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index," it added. "We warn that this study does not establish a cause-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship." In November 2004, researchers from Columbia University in New York City, New York demonstrated a clear link between the risk of being obese and hours of nightly sleep, finding that people aged 32 to 59 who slept four hours or less per night were 73% more likely to be obese than people who slept between seven and nine hours per night. 查看更多

A recent study offers a picture of how dangerous 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. However, the possibility of death for drivers between 30 and 59 decreases with each additional passenger.

It was also found that the death rates for teenage drivers increased greatly after10 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 University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving experience. Both he and the author of the study believe that the way to help solve the problem is to have states setting up so-called graduated licensing systems (等级执照制). A graduated license requires that a teenager first prove himself able to drive in the presence of an adult, fol­lowed by a period of driving with a limited number of passengers, before graduating to full driving on his own. About half of the states now have some sort of graduated licensing system in place. The systems have reduced teenage driver crashes, according to recent studies.

1.Which of the following situations is most dangerous according to the passage?

    A.Adults giving a lift to teenagers on the highway after 10 p.m.

    B.A teenager driving after midnight with passengers in the car.

    C.Adults driving with three or more teenage passengers late at night.

    D.A teenager getting a lift from a stranger on the highway at midnight.

2.According to Robert Foss, the high death rate of teenage drivers is mainly due to _______.

    A.their frequent driving at night             B.their improper way of driving

    C.their lack of driving experience           D.their driving with passengers

3.A suggested measure to be taken to reduce teenagers' driving accidents is that ________.

    A.driving in the presence of an adult should be made a rule .

    B.they should be stopped from taking on passengers

    C.they should not be allowed to drive after 10 p. m.

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 life from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal(致命的)accident as a teenager driving alone. By contrast(相比之下), the risk of death for drivers between 30 and 59 decreases with each additional passenger.

The author 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 University of North Carolina Highway Safety Research Center, 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(规定)so-called graduated(分档次)licensing systems, in which getting a license is a multistage(多阶段)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.

A.Adults giving a lift to teenagers on the highway after 10 p.m.
