     If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers

are overweight, and some of this because of their bad eating habits. Most teenagers love food with a lot

of fat, oil, salt, and sugar. People often call this kind of food "junk food".

     But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don't have

breakfast before they go to school. During the day, some don't have a proper meal for lunch. In a recent

survey  at one school , scientists found that  over  two thirds of   the students didn't follow a healthy diet.

They didn't like vegetables, and many of them didn't like fruits. They preferred to eat food with a lot of

salt, sugar, or fat.

     Parents today also worry about their children's diet. Some doctors give the following advice:

     Teenagers shouldn't eat too much junk food.

     Teenagers shouldn't eat food with too much salt. Salt can cause high blood pressure in the future.

     Teenagers should eat food with less fat, oil, and sugar.

     Teenagers need to eat some fruits and vegetables every day. fruits and vegetables are rich in vitamins

and have little fat.

     Teenagers need to drink more milk. Milk will help their bones grow.

     Teenagers need to eat breakfast every day. This is good for their body and mind

You will probably try harder to get more sleep once you see how much better you feel with even 30 minutes more sleep.

Getting more sleep is sometimes merely a matter of scheduling. In the next couple of weeks, try to get rid of one or two things from your morning and evening routine. If morning is your downfall, shift(转移) some of your morning routines to the night before or putting something off until your break at lunch. If late afternoon and night are your downfalls, do the same.

You don’t really need to watch the news. It’s depressing. If something important happens today, you will find out tomorrow at work. At least skip(略过) the weather. Right after dinner, go to a major search engine, and type in “national weather” and the name of your town. You will see a two-line weather report from the National Weather Service. This will save you several minutes of watching the weather on television.

If reading helps you, take a boring book or magazine to bed with you. Paperbacks(平装本) are not as heavy and are easier to read in bed. 

If you have a partner or roommate, maybe you can take turns with a neck and shoulder massage at night instead of television.

Make sure you are ready for sleep when you go to bed. __________ such as televisions, computers, and video games wake us up. Avoid them for at least an hour before you plan to go to bed.
