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(生物学上)these sleepyhead(贪睡者)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(迁移)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.”

For the 17 years my life was very happy. Then the first sad thing happened. My mother became very ill. Just before she died, she asked Elizabeth and me to go to her room. She said, “Victor and Elizabeth, I’m very happy because you love each other, and because one day you’ll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear? I can die happy if you look after them when I have gone.”
My mother died and we were very sad, because we loved her so much. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother’s death. The time came for me to go to university(大学). I didn’t want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had gone alone.
On my first day at university I met Professor Waldman. He gave a wonderful talk to all the students. He ended his talk by saying, “Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can.”
After the professor’s talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the tree. From then on, I wanted to use electricity to help people, and I wanted to discover the secrets of life. I decided to work on these two things.
I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist.
The professor and other important scientists helped me. I was interested in my work and I did not take one day’s holiday during the next two years. After two years, I had discovered many things and I built a scientific machine that was the best in the university. My machine would help me answer the most important question of all. How does life begin? Is it possible to put life into dead things? To answer these questions about life I had to learn first about death. I had to watch bodies from the moment when they died and the warm life left them. In the hospital and in the university, I watched the dying and the dead. Day after day, month after month, I followed death, so it was a dark and terrible time.
I built a tall mast(桅杆)about 150 metres high, which is higher than the tallest building in the city, to catch lightning and send the electricity down to my machine in the lab. I believed I could use that electricity to give life to things that were dead.
Then one day, the answer came to me. Suddenly I was sure that I knew the secret of life.

A．Elizabeth married shortly after Victor’s mother died.

The San Diego Zoo has been a lovely home for giant pandas since two of the black-and-white bears came to visit in 1987. This week there was snow in San Diego—well, at least for a lucky group of giant pandas.
Over 15 tons of snow was blown into the San Diego Zoo's panda area on Tuesday morning to give the endangered bears a chance to play. They would experience the snow just like living in their natural habitat.
The snow day was a first for Xiao Liwu whose name means "Little Gift." He was the sixth baby panda born to Bai Yun. Xiao Liwu was jumping on Mom, playing with her and getting used to being thrown in the snow by mama bear. Jennifer Becerra, San Diego Zoo keeper said, "He was really enjoying the snow and running around. I've never seen him so happy."
All the San Diego Zoo’s giant pandas are from China, as part of a long-term captive breeding(人工养殖) program. Four of Xiao Liwu's brothers have already been moved from California to China.
Today there are 44 giant pandas living in zoos outside of China, where the bears' only natural home is. As just 1,600 pandas are thought to be left in the wild, researchers insist that captive breeding is an important way to study and protect the endangered pandas. Not only because of the habitat loss from human activities and low reproductive rates(繁殖率), giant pandas' survival is also affected by climate change. A study showed that global warming could kill much of the bears' main food, bamboo, over the next century.
Why was the snow blown into the San Diego Zoo's panda area?

A．To stop the bamboos from dying.

B．To give the pandas a chance to play.

C．To help the pandas live in their natural habitat.

D．To make Xiao Liwu happy.

What’s the relationship between Bai Yun and Xiao Liwu?

A．Wife and husband.

B．Father and daughter.

C．Sister and brother.

D．Mother and son.

What is NOT the factor that influences the giant pandas' number?

A．The loss of habitat.

B．Low reproductive rates.

C．Human research.

D．Climate change.

Which of the following is the best title of this passage?

A．Giant pandas in San Diego Zoo

B．Giant pandas in danger

C．Xiao Liwu’s happy time

D．How to protect giant pandas

Which of the following is true according to the passage?

A．Captive breeding is the most useful way to protect giant pandas.

B．More than 44 giant pandas live in zoos outside of China now.

C．China is the only natural home of giant pandas.

D．Xiao Liwu was afraid of being thrown in the snow by mama.
