1．As space science develops，man has learned more and more about space．Space is not only amazing but also dangerous．While working in space，spacemen are facing danger as well as success．Scientists have found out that the radiation （辐射） is the greatest danger to spacemen in space．When spacemen are working in space，they are in danger of the radiation from the sun and other stars，which is bad for their health．The harm of the radiation won't be found until their children even grandchildren are born．Some special medicine may work a little，but no really effective medicine has been found so far．

Scientists are watching and reporting any possible danger all the time．They are working to deal with space rubbish．Although space is really dangerous，it interests many people on the earth．In the near future，it may become possible for people to spend a few days in a space hotel．We may even choose to leave the earth and live in space in a few years．So we should do something to help improve the space environment．

16．"If you consider getting older with needing less sleep，it's not true!"says Robert Oexman．Besides sickness，medicine and pain，Dr．Oexman looks at his patients'nighttime habits，which cause the most sleep problems．So，how are you destroying your sleep？
•Watch TV until you fall asleep
It has nothing to do with what you watch．It's because you face TV's bright light．So even if you nod off in front of the TV，for example，you possibly can't stay asleep for long．
So an hour before bedtime，treat yourself like a baby：a warm bath．But no reading or writing on your computer before bed or in the middle of the night．
•Exercise too close to bedtime
Remember how poorly you sleep when you have a fever，never really feeling rested？Well，heavy exercise too close to bedtime has the same effect-it raises your body temperature，so that your sleep is not at best until your body temperature drops to normal，which may take several hours．
So no exercise at least three hours before bedtime to make sure your body temperature is normal．
•Eat fatty，heavy foods too close to bedtime
If you've ever tried to go to sleep after eating a fatty meal，you've probably found the discomfort of stomach and you are less likely to fall asleep．
So try to eat your last meal of the day at least 2-3hours before bedtime．Should you feel hungry before bed？So have a bowl of cereal or a small boiled potato．Or maybe have a serving of jasmine rice．

6．根据短文内容，完成下面的表格．
Have you ever met anyone of your age from America？Do you think you would have a lot in common with middle school students there？
With only one look，you can see lots of differences．For example，classes in American schools are smaller than yours．Most classes have no more than 30students．Most students in the US don't wear school uniforms．And they don't have group exercise each day as the way you do．If they say your exercises，they would think you were very strange．
In fact，Chinese students and American students have very different lives．
What's the first thing you think about when you wake up in the morning？It's probably your lessons at school．Chinese students are very hard-working，always under lots of stress from their parents and teachers．Chinese students study hard at night，and sometimes even on the weekend because their exams are very important．
For Chinese students，school is life，but not for American students．They don't have to worry about passing exams all the time，so they can spend time doing things they enjoy．Kids do different things for fun，like playing sports，making music or surfing the Web．
Many American teachers think that just studying hard isn't enough to make a good student．They encourage students to become well rounded by trying lots of different things．
