Do you find that late at night, your homework done, you aren't tired enough to sleep? In fact, you could get out of bed and go for a run, or play a quick game of basketball? It's not a good feeling because, although you don't feel sleepy, you certainly will in the morning．
It's probably not coffee or tea or other stimulants （刺激物） that are the problem．Indeed, it may not be a problem at all, according to some researchers, just the way the teenage body works．But not all schools seem to realize this．
It seems that some American schools are getting the message and giving teenagers more time to sleep in the morning．They've found that starting after 8 am makes students more likely to turn up on time to school, do better work, and generally feel happier．
But in most American schools after school activities like sports and bus routes are given as reasons for a morning start time between 7 am and 8 am．
All this, the US National Sleep Foundation （美国国家睡眠协会） says, has serious consequences for teenagers．It means they don't get the 8．5 to 9．5 hours of sleep a night they need．In fact, some teens get just 7 hours or less under the covers．
Researchers have come to the conclusion over the last 10 years that teens cannot easily fall asleep until about 11 pm and need to sleep until about 8 the next morning．
Mary Carskadon of Brown University was in charge of a study of teen saliva （口水）．Her team measured the amount of sleep-producing hormone （荷尔蒙） in the saliva．
She found teens have a higher hormone level late at night than either adults or young children．It also remains high the morning after．Why this is the case is not yet clear to scientists．But experts say they do know that the consequences to teenagers sleep deprivation （剥夺） are more serious than classrooms full of sleepy kids．
Falling asleep at roll call （点名） is just the beginning of the problem．In her book Snooze … or Lose Helen Emsellem says that sleep-deprived teens get sick more easily, are prone （易于） to headaches and get poorer grades．

2．According to researchers, starting schools later in the morning is likely to ______．

3．Which group has the highest sleep-producing hormone level in their saliva late at night?

C．The middle-aged． D．Old people．
4．Which of the following is FALSE?
A．Early morning starts are to blame for teen sleep deprivation．
B．Many American teenagers have trouble getting enough sleep．
C．Many American schools argue that after school activities help teenagers sleep．
D．The book Snooze … or Lose stresses the importance of good sleep for teenagers．
5．Which of the following can be the best title of the passage?
A．Live Longer with better sleep B．More Sleep needed

查看习题详情和答案>>The Guidance Department (教导处) at Burrville High School has a staff (职员) of eleven. Most of their work is done with the students. But the staff sees a lot of parents, too.
“Parent meetings form a clear monthly pattern,” says Mildred Foreman, Guidance Director. “This pattern stays much the same from year to year. The busy months are October, March and May.”
September starts rather slowly. Few parents come in. Most of them want to discuss the schedules. October brings many behaviour problems. Some parents are called in. Others come by themselves. Things quiet down in November. December is a quiet month. “It’s the holiday,” Ms. Foreman says. “People want to come in, I know, but they decide to wait until after New Year’s Day.”
Report cards go home just before Christmas holidays. Bad marks bring parents in as school reopens. This happens again in March, another report card month. May is always the year’s busiest month. That’s when parents realize that their children might be held back (留级). They come in to see if anything can be done before things are decided in June.

One of the most exciting and attractive fields of work today is the fashion industry. Some of the most well-known people in this industry are the fashion designers with unbelievable financial (金融的) Kingdoms. But most of the clothes that you wear have been designed by people that the world has never heard of. Although these unknown fashion designers will never make a very large amount of money as their famous workmates, most still would not think of changing their careers. They are doing what they love.
If you spend hours looking through fashion magazines and like making your own clothes, a career as a fashion designer might be right for you. You do not have to go to design school to become a fashion designer, but many people who want a career in this field do. One of the most famous places to study is the Fashion Institute of Technology in New York City. It is located in the heart of the “garment” district on Eighth Avenue, also known as Fashion Avenue.
Becoming a fashion designer is not just a matter of classroom education. Students know that they cannot just leave school and start designing on their own. Many think that they need at least four years’ experience working for someone else after they graduate. The best schools encourage students to work closely with the fashion industry while they are still studying.
You need ambition (抱负) and hard work to get a career in fashion. Students often work 12 hours a day. They are encouraged to have realistic ambitions and not to expect success overnight, if ever. Success means finding a job in the fashion industry and more years of hard work.
