1 . 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’ll 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（有价值的）part of all. But this is offer thrown away with the skin.

If you cannot eat the whole potato, you can eat the outside rim first and leave the inside.
