It’s nearly noon on a Saturday and you can’t believe it: your teenager is still in bed, sleeping away. But before you wake him up---mumbling to yourself that you can’t believe what a lazybones he is---you should know that he probably needs all the zzzs he can get.

As much as nine hours of sleep a night, in fact. Furthermore, teens’ circadian rhythms (i.e., processes that occur once a day) mean that young people would rather stay up past midnight and rise after 9 a.m. The result? Many teens stay up late, drag themselves out of bed early for school and try to make up the sleep debt on the weekends---or in class!

“There’s a biological reason why teens stay up late and want to sleep late,” says Dr. Stan Kutcher, the Sun Life Chair of Adolescent Mental Health at Dalhousie University in Halifax. “Their natural sleep-wake cycle changes as part of the maturation process. And because of changes in their social activities, recovering from sleep debt is more problematic.”

Teens need extra sleep for several reasons. First, their brains are changing. “The brain is reorganizing itself, laying down new pathways. What we’re seeing is a relationship between brain redevelopment and an increased need for sleep,” says Kutcher. As well, growth hormones are released during sleep, so adequate sleep is crucial for adolescents’ physical development. In addition, everything adolescents have learned in school that day is being processed and locked into long-term memory during sleep. Sufficient sleep also plays a key role in overall physical health. The immune system, for example, needs deep sleep to become and remain robust(healthy).

Staying up late on school nights means that, on average, teens get between six and a half and seven hours of sleep a night---about two hours less than they need. As a result, many either doze off in class or have trouble concentrating. Some of the behavioural problems and irritability in teens can be linked directly to sleep deprivation(損失), Kutcher says.

Then there’s the breakfast issue. Dr. Carlyle Smith, a sleep researcher and a psychology professor at Trent University in Peterborough, Ont., adds that many teens simply cannot tolerate food when they first wake up, so skipping breakfast becomes another factor in reduced alertness in class. The most obvious solution to the teen sleep problem is to have school start later in the day, but initiatives(積極性) toward this across the country have gone nowhere, Smith says, mainly because of costs and resistance from school boards and teachers.

So for now, just sympathize with your teens. Encourage them to go to bed, if not early, then at least at a regular time, so they won’t develop insomnia from erratic(不穩(wěn)定的) schedules. Warn them not to have too many caffeinated drinks before bed. And don’t let sleeping away the weekend become an issue to fight over. Schedule family activities to take place later in the day on weekends and let them sleep in. “If you want your kids to grow and remember stuff, let them sleep,” says Smith. “It’s not laziness. Their brains are working really, really hard.”

1.The word “zzzs” (Paragraph 1) most probably means __________.

A well-dressed man came into a famous jeweler shop. He explained that he wished to buy a pearl (珍珠) for his wife's birthday and that the price didn't matter since business had been very good for him that year. After examining a number of beautiful and valuable pearls, he chose a nice black one that cost $ 5,000. He paid for the pearl, shook hands with the jeweler and left.

       A few days later the man returned and said his wife had liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality(質(zhì)地) as she wanted a pair of earrings (耳環(huán)) made. "Can you give me any advice on how to get such a pearl?" said the man. The jeweler replied,   "I would say it's nearly impossible to find an exact one like that pearl.”

       The rich man asked the jeweler to advertise(登廣告) in the newspapers, and offered $25,000 for the  matching pearl. Many people answered the ad(廣告), but nobody had a pearl that was just right. Just when the jeweler had given up hope, a little old lady came in. To his surprise, she pulled the wonderful pearl from her handbag. "I don't like to sell it," she said sadly. "I inherited(繼承) it from my mother, and my mother inherited from hers. But now I really need the money. "
