Most American children eat potatoes. But many children don’t know which part of the potato is the best for food. Take a knife and cut a slice of potato from the middle as thin as paper. Hold the slice of potato against the light and look at it. You will see that the potato has a skin, an outside rim (边缘) and an inside part. The outside rim, which is right under the skin of the potato, is more valuable(有价值) than other parts. But people usually throw it away with the skin. Even the skin itself is better for food than the inside part. When eating a cooked potato, if you choose the inside and leave the outside, you are throwing away the best part of it. If you can’t eat the whole potato, you can eat the outside rim first and leave the inside.

A. It has only one part, an outside rim.

( )2. What’s the best part of the potato?
A. The outside rim. B. The inside part.
C. The middle. D. The skin.
( )3. What should you eat first if you can’t eat the whole potato?

( )4. In fact the skin is ____.
