Sleep and Teens--Biology and Behavior
How much sleep do teens need? And how much sleep are they realistically getting? Based on current data, most teens need about 9-plus hours to have the best or most suitable sleep night. 51 Many factors combine to decrease sleep in adolescents. We can think in general of two major factors: biological, the brain processes that regulate the amount and timing of sleep, and behavior, all the psychological, parental, societal, cultural features of teen’s life.
__52 These changes lay the ground work for the biological night to occur later during the teen years than before. Circadian Rhythms (daily biological clock) seems to slow down as young people progress through the middle school years. At the same time, the sleep pressure system appears to change in a way that makes it easier to stay awake longer, though without changing the amount of sleep that is needed.
Moreover, many teens have a \playground\in their bedrooms: television, computer with 24/7 Internet access, telephones, electronic game stations, MP3 players, and so forth. These technologies provide instant and constant contact with peers. Societal and media pressure to consume these technologies is now higher than ever. Yet society also requires that teens go to school at a time of day that is at odds with their biological and social lives. So we see teens turn to caffeine, late-night Internet and cramming in activity after activity as a means to keep awake. _____53 . Problems emerge for lack of sleep. 54 For some, grades begin to suffer as they struggle to keep awake 9
during class and while doing homework. And others may simply feel moody, never knowing how to feel or do their best. Worse still, many teens suffer from both physical and mental illness.
___55 The earlier teens can start this good sleep habit, the easier it will be for them to stay healthy, happy and smart.
A. Sleep experts recommend teens keep consistent sleep and wake schedule B. Teens may schedule sleep like any other daily activity and make sleep a priority C. Then they are trapped into a terrible situation where they would never get enough sleep D. The sleep-wake bio-regulatory factors appear to change significantly during adolescence E. Some teenagers struggle to wake up in the morning, often resulting in late or missed school F. Teens may be driven to things that can wake them up because they'll fall asleep if they do not G. However, it is indicated that most teens fall short of this goal, many by a considerable amount. 第三部分：书面表达（共两节，35分）

Hello, everybody! I’m very glad to share my dream with you.
I have a dream that one day I could be a pianist. I dream of playing a sweet tune for those who need music, bringing happiness to sorrowful souls and enthusiasm to weary spirits.
I love music, and I love the feeling of playing music in front of the audience. Of all the instruments, the delicate yet powerful sound a piano makes impresses me most.
It’s clear that I have a long way to go before I realize my dream. Therefore, I will practice every day as long as time permits and learn as many songs as I can. I will put my heart into my pursuit of music and never give up.
I am confident that one day my dream will come true. Thank you. 第二节（20分） One Possible Version

spring, a candy-coated haws stand caught his attention. Having never tasted a candy-coated haw, he immediately went up to buy one.
However, the vendor shook her head when seeing the 100-yuan note Jim handed over to her. She had no change! How disappointed Jim was! He was about to quit when I took out my cellphone, scanned the QR code on the stand and paid the vendor 5 yuan.
Jim was surprised at what I had done. Then I explained to him that nowadays in China QR codes were everywhere, and we could pay with a cellphone for almost everything. “Wow!” Jim said, “The candy-coated haw tastes great, and the payment method seems even greater!”
