Question

9．Up to 65% of children don't get as much sleep as they should do，and this can make them nervous and slower at school，scientists say．
So how long should young people sleep each night？The answer is between eight and ten hours．If you don't get enough sleep at night，you'll have less energy the next day．
But the scientists say many children have missed out on 4，500 hours of sleep by the time they are seven years old．They say that children miss sleep because they have TVs and computers in their rooms，and busy parents don't read to their younger children at night any more．The traditional"bedtime story"helps children to relax and fall asleep peacefully．Children with TVs and computers in their bedrooms were more likely to sleep badly，and to get less than eight hours'sleep．Even losing one hour's sleep a night can mean that children do less well at school．
German scientists think that your brain （大腦） keeps working while you are asleep．To show that they were right，they gave two groups of people a problem to work out．One group went to sleep，and the other group stayed awake．The result？The people who slept worked out the answer more quickly．
This showed that their brains had been trying to find the answer while the people were asleep．So，make sure you get enough sleep tonight，and you'll be at your best tonight，and you'll be at your best tomorrow!

Answer 1

分析 文章大意：
本文主要講述的是學生睡眠和學校表現之間的關系．現在，65%的學生在晚上會玩電腦、看電視，以至于沒有得到足夠的睡眠時間，第二天在學校就會出現緊張，反應慢的問題．同時，科學家還發現，即使是睡覺的時候，大腦還是在工作的．由此，科學家告誡孩子們，一定要保證充足的睡眠．

解答 56．C，推理判斷題，文中提到"Up to 65% of children don't get as much sleep as they should do"65%的學生睡眠不足，由此確定選擇C．
57．B，推理判斷題，文中提到"this can make them nervous and slower at school"如果睡眠不足，你就會沒有精神，表現出來就是緊張，并且反應比較慢，由此確定選擇B
58．B，推理判斷題，文中提到"They say that children miss sleep because they have TVs and computers in their rooms"影響孩子們睡眠的一個重要原因就是房子里的電視和電腦，由此確定選擇B．
59．A，推理判斷題，文中提到"German scientists think that your brain （大腦） keeps working while you are asleep"德國科學家說在睡覺時大腦還在工作，后面講述了驗證這一理論的實驗，由此判斷選擇A．
60．C，推理判斷題，文中最后一句話提到"So，make sure you get enough sleep tonight，and you'll be at your best tonight，and you'll be at your best tomorrow!"所以，你要好好睡覺，這樣的話你才能在第二天表現出色，由此確定選擇C．
