15.There is a serious problem to our earth.That's warming.It's true that the carbon dioxide (二氧化碳)put up into the air is warming the earth.It is clear that average (平均)temperature has risen over the last century.Not everyone can believe that carbon dioxide is the main reason.A new study shows it is not all the fault (过失)of the carbon dioxide.Some scientists studied the sun and found that when the sun becomes more active,the earth warms up.When the sun quiets,temperature goes down.Some scientists aside the sun's change may be more important than carbon dioxide in warming the earth.
We can't change the sun.So in order mother to make  the earth warm up,what we can do is to control (控制)the amount of giving off carbon dioxide into the air directly (直接的).We should ride a bike or walk when we go out.It is not only good for our environment,but also good for our health.

A.When the sun becomes bigger.
B.When the sun becomes more active.

8.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 4,500hours 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 (大脑) 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!

51.What problem do more than a half of students have?B
A.They don't get on well with their studies.B.They don't  have enough sleep at night.
C.They don't relax themselves at school.D.They don't follow their school rules
52.If you have less energy the next day,you'll probably feelA.
A.sleepy,slow and nervous             B.tired,bored and worried
C.afraid,alone and angry               D.dull,lazy and crazy
53.According to the third paragraph,what has worst influenced many children's sleep?D
A.Their parents'noise.B.Bedtime stories.
C.Too much homework                  D.TV and computers
54.The German scientists'experiment showed thatC.
A.our study depends on our sleep           B.our sleep helps improve our health
C.our brain works while we sleep           D.our brain works faster during sleep
55.This passage in mainly written forD.
A.parents      B.school teachers      C.scientists     D.young students.
