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 (确保) bedtime. Instead, it may be that biologically these sleepyhead 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.
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 nigh 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 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, adolescent are up against difficulties when it comes to trying 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.”
1.Carskadon suggests that high schools should not start classes so early in the morning because ________.
A. it is really tough for parents to enforce bedtime
B. it is biologically difficult for students to rise early
C. students work so late at night that they can’t get up early
D. students are so lazy that they don’t like to go to school early
2.The underlined phrase “nod off” most probably means “ _______”.
A. turn around B. agree with others C. fall asleep D. refuse to work
3. What might be a reason for the hard transfer from middle school to high school?
A. Adolescents depend more on their parents.
B. Adolescents have to choose their sleep patterns.
C. Adolescents sleep better than they did at childhood.
D. Adolescents need more sleep than they used to.
4. What is the test mainly about?
A. Adolescent heath care. B. Problems in adolescent learning.
C. Adolescent sleep difficulties. D. Changes in adolescent sleep needs and patterns.

●The first double hand transplant patient in the US has left a hospital after medicine cleared up
small red spots on his skin that signaled he might be rejecting his new hands. Jeff Kepner, a 58-year-old former chief cook in a restaurant, lost his hands and feet a decade ago to a bacteria infection. The donor was a 23-year-old man.
●A second major storm in less than a week was blowing yesterday toward the Washington area, where federal government offices were closed for a second day and workers struggled to restore power knocked out by a weekend heavy snowstorm. The storm could leave as much as 20 inches (50 centimeters) of new snow in Washington and nearly as much near Philadelphia –a Northeast travel-hub by tonight.
●British Prime Minister Gordon Brown will give evidence to a public inquiry into the Iraq War in early March, officials for the inquiry said yesterday. Brown’s appearance, just weeks before an election expected in May, could hit the ruling Labour Patry’s attempts to catch up in the polls （民意调查）behind the opposition party Conservatives. Brown, who will be questioned about his time as prime minister, will be a witness in the highest position at the inquiry since former Prime Minister Tony Blair’s appearance last month.
●The head of the UN agency aiding Palestine refugees （难民）is warning a funding shortfall and appealing for another $100 million. Filippo Grandi says the money is necessary for education, health and social services for 4.7 million Palestinian refugees scattered across Jordan, Syria, Lebanon, the West Bank and the Gaza Strip. The agency’s 2010 budget is $620 million, and it expects a shortfall of $140 million. The agency says $100 million is necessary for basic services.

C．another storm will hit Washington area in less than a week
D．the electricity supply was cut off in Philadelphia a week ago
66．According to the passage, Gordon Brown .
A．is the leader of the ruling Labour Party in Britain
B．will send army to the Iraq War in March this year
