Picture the two very fat students go into an ice cream shop.They sit down and begin to enjoy their sweet food.Then they go to a health club to have a good exercise.They want to work off all the fat they ate.Who would be so silly?Some people would.They care about their health.But they have some very bad habits.
Many people know the good of eating healthy foods.In school,child learn to eat diferent kinds of healthy foods.Now people know what kinds of foods are dangerous for health.They also know it's not good to eat too many sweets or fats.So they choose to eat the best foods.
In the past twenty years,many Americans have joined health clubs to do exercises.Some people even bought sports sets to have exercises at home.But now there arefewer people to do exercises than before.Among middle school students,only about one third exercise three times one week.The others watch TV at least an hour every day,and some students even sit in front of the TV more than three hours a day.So many middle school students become fat.
In China students do not watch TV every day,but they watch a lot in weekends and holidays.Most students do not join health clubs,so some of them exercise very little.
All the people around the world enjoy good health and know how to make themselves more healthy.They just need to do it.
