It is reported that many middle school students are just not getting enough sleep, especially during the school week．The problem seems to get worse as they get older．Grade 7 students sleep 8．4 hours a school night, and Grade 9 students only 6．9 hours．

（3）It’s also reported that not getting enough sleep can cause problems in a student’s life．Many students fall asleep in school or while doing their homework, so it is not surprising that they get lower grades than those who get enough sleep．

Scientists suggest nine hours a night for middle school students．Of the students who feel unhappy and nervous, 73% don’t get enough sleep at night．Why aren’t students getting enough sleep? Many students have one of the following things, like telephone, television, or computer in their bedrooms．Using them on a school night not only takes their time away from homework, but also makes it difficult for them to fall asleep．（4）As a result, many students can't fall asleep before 11 pm, yet they must get up early to go to school the next day ．

    Scientists also suggest students should not do exciting activities for an hour before bedtime．

　　It isn't strictly true that one half of the world is rich and the other half is poor. It is one-third that is very rich and two-thirds that are very poor.

　　People in the rich countries don't understand the great difference between them and those in the poorer countries. A very simple example is that a dog or a cat in north America eats better than a child in the poorer countries. A fisherman in South America may be catching fish which is processed into pet food, and his own children are not getting enough to eat for their bodies to grow properly.

　　Although a lot of the world's natural resources like oil come from these poorer countries, people in the richer countries are using about sixty times as much of these resources as people in Asia or Africa. And it's the richer countries that decide what kind of prices they are ready to pay for these resources. And the prices the richer countries get for their own exports, however, are always rising. So they are getting richer and richer and the poorer countries are getting poorer.
