四、阅读与回答问题
If you go to a fast food restaurant, you will probably see a lot of young people. Today, many teenagers are overweight (超重的), and some of this is because of their unhealthy eating habits. Some teenagers love food with a lot of fat, oil, salt and sugar. People often call this kind of food "junk food".
But eating fast food is only one of young people's bad habits. Some don't have breakfast before they go to school. During the day, some don't have a right meal for lunch. And they dislike vegetables or fruit. In a study at one school, scientists find that more than 45% of the students don't follow a healthy diet.
Parents worry about their children's diet. Doctors give the following advice:
*Teenagers shouldn't eat too much fast food.
*Teenagers shouldn't eat food with too much salt. Salt can cause high blood pressure (血压) in the future. Teenagers also should eat food with less fat, oil, and sugar.
*Teenagers need to eat some vegetables and fruit every day. Vegetables and fruit are rich in vitamins and have little fat.
*Teenagers need to drink more milk. Milk helps build strong bones.
*Teenagers need to eat breakfast every day. This is good for their bodies and mind.
