So how long should young people sleep each night? The answer is between 8 and 10 hours. If you don’t get enough sleep at night, you’ll have less energy the next day. But the researchers 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 keeps working while you’re 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, suggesting 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 tomorrow! 26. What happens to children at school if they don’t get enough sleep? A.They walk more slowly. B.They can relax. C.They watch more TV. D.They do less well at school. 27. The main idea of the second paragraph is . A.how much sleep we need B.children don’t get enough sleep C.our brains never really go to sleep D.TVs and computers are the problem 28. How does a bedtime story help children get a good sleep? A.It helps children to relax and fall asleep peacefully. B.Children lose more sleep. C.Children have more energy. D.Children get to sleep later. 29. Why is it better to sleep in a room without a TV or computer? A.You can read stories before you go to sleep. B.You sleep better and get more sleep. 7 C.You have less energy. D.Your brain works better. 30. What did the German scientists’ experiment show? A.Sleep helps children learn to read. B.Losing sleep means children don’t learn well. C.Your brain works while you are asleep. D.Parents should read bedtime stories. Healthy Eating Healthy eating is important for us. What and how should we eat to be healthy? First, we must have enough food, never too much or too little. The food must be clean and we should cook it properly. Second,it’s very important for us to keep a balanced diet. Different kinds of foods are necessary, such as rice, bread, meat, fish, eggs, milk, fruit and vegetables. Rice and bread give us energy. Meat, fish, eggs and milk help our bones grow. Fruit and vegetables make us healthy. Third,we should eat regularly. It’s said that half of the students don’t have a regular breakfast or don’t eat anything in the morning. It is bad for their health. In fact,a good breakfast keeps us strong. In short, we should not only eat enough food and healthy food but also eat regularly. 第1题判断正(T)误(F);第2题完成句子;第3~4题简略回答问题;第5题将文中画线句子译成汉语。 31. We don’t need to eat enough food. ( ) 32.
