Most American children eat potatoes. But many children don't know what of the potato is the best for food. Take a knife and cut from the middle of the potato a piece as thin as paper. Hold the piece between your eyes and light. You will see that the potato has skin (皮), an outside rim (边缘) and an inside part. The outside rim which is right under the skin of the potato, is the most valuable part of all. But this is often thrown away with the skin. Even the skin itself is better for food than the inside. When eating a cooked potato, if you choose the inside and leave the outside, you are throwing the best part of it. If you can't eat the whole potato, eating the outside rim and leaving the inside will do.

[ ]
A.It has only one part, outside rim.
B.It has two parts, skin and outside rim.
C.It has three parts, skin, outside rim and an inside part.

If you go to a fast food restaurant, you will probably see a lot of teenagers (青少年). Today, many teenagers are overweight, and some of this is 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 (调查) at one school, scientists found that over two-thirds of the students didn't follow a healthy diet (饮食). They didn't like vegetables, and many of them didn't like to eat 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 (高血压) 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 (维生素) 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.
