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.”

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

The underlined phrase “nod off” most probably means “ _______”.

A. turn around    B. agree with others  C. fall asleep  D. refuse to work

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.

A jobless man applied for the position of “office boy”at Microsoft. The HR manager interviewed him and then watched him cleaning the floor as a test.
“You are employed,” he said. “Give me your e-mail address and I’ll send you the application to fill in, as well as date when you may start.”
The man replied，“But I don’t have a computer, neither an e-mail.”
“I’ m sorry，” said the HR manager.“If you don’t have an e-mail，that means , you do not exist. And who doesn’t exist cannot have the job.”
The man left with no hope at all. He didn't know what to do with only ten dollars in his pocket. He then decided to go to the supermarket and buy 10 kg tomatoes. He then sold the tomatoes from door to door. In less than two hours, he managed to double his capital. He repeated the operation three times, and returned home happily with 60 dollars.
The man realized that he could survive in this way, and started to go every day earlier, and return late. Thus, his money doubled or tripled every day. Shortly, he bought a cart, then a truck, and then he had his own fleet of delivery vehicles. Five years later, the man is one of the biggest food retailers(销售商) in the US.
He started to plan his family’s future and decided to have a life insurance. He called an insurance broker（经纪人）and chose a protection plan.
When the conversation was concluded the broker asked him his e-mail. The man replied, “I don’t have an e-mail.”
The broker answered curiously,“You don’t have an e-mail, and yet have managed to build an empire. Can you imagine what you could have been if you had an e-mail?" The man thought for a while and replied,“Yes，I’d be an office boy at Microsoft!”
【小题1】The underlined word “tripled” can be replaced by             .
