Why is that many teenagers have energy to play computer games until late at night， but can't find the energy to get out of bed in time for school？ According to a new report， today's teenagers are getting so little sleep but their health is in danger．

This raises serious questions about whether being short of sleep is influencing children's ability to pay attention at school． Research has shown that losing even just half an hour's sleep at night can have deep influences on how children perform the next day．

So why aren't teenagers getting enough sleep？Some experts suggest that televisions， computers and mobile phones in children's bedrooms may cause problems．Instead of reading a book at bedtime，children are playing computer games，surfing the web，sending messages， or watching television．As these new pre-sleep activities have become more common，more traditional ones such as reading have become less，Dr．Luci Wiggs，a researcher at Oxford

University's Section of Child and Adolescent Psychiatry said，“One of the problems with these pre-sleep activities is that they do not have clear start and end times which leads to being short of sleep．”

Research has shown that teenagers have different sleep patterns from adults．Human bodies produce melatonin（褪黑激素）to help fall asleep． Most adults start to produce melatonin at

about 10 pm，while teenagers only begin to produce it three hours later．It is possible that this delay in melatonin production is caused by the behaviors of teenagers such as playing with phones late at night．

Problems about sleep- who needs how much and when -are usually connected to students' achievements． But modern brain researchers say it is time that more schools wake up to both biological and social facts and make a better timetable for their teenager students．

A.It's very common for teenagers to have less sleep．

B.It doesn't matter if children sleep half an hour less．

C.Being short of sleep has influence on children．

D.A good night sleep at weekends helps children study well．

2.According to Dr．Luci Wiggs，．

A.too many pre-sleep activities take up teenagers' sleeping time．

B.playing computer games before bedtimes does harm to health．

C.fewer and fewer children read books at bedtime today．

D.teenagers shouldn't watch TV before they go to sleep．

3.What does the underlined word 'delay' mean？

A.Rushing． B.Changing． C.Putting off． D.Cutting off．

During my travels through the mountains of Greece I was only ever scared once, it was dusk and as I walked. I came across six large wolves that were feeding on the body of a dead animal. I had heard many stories about wolves as a child and it was this animal that I feared more than any other. The wolves before me were huge, at least 6 feet long and covered with thick grey fur.

As I went near, the wolves left the blood-covered snow that surrounded the body and started walking towards me, one after another. They stopped about 20 meters from me and stared. The lead wolf raised his head into the air and took in a deep breath, as if he was smelling me. The animals looked both beautiful and frightening, but I knew I couldn't show them my fear. As I drew nearer, the lead wolf raised his head once more but this time let out a long, loud cry. The awful cry rang out across the silent valley. I had never heard a more frightening sound. I was almost certain it was a sign to be death.

Every moment I expected to see the pack of wolves’ dash at me. I knew my only hope was to pretend I had no fear. I walked past the line of wolves, like a general moving among his soldiers. They cried out loud again. But when they saw that their cry did not cause me to change my direction or make me run they feared to come after me, so they let me pass and returned to the dead animal.

If I had turned back or tried to run away when they marched out to meet me, I am certain the whole pack would have attacked me in a moment. But my show of false courage intimidated them and kept them back.
