Question

　　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.

解析：

整体把握：这是一篇科普性短文，我们只知道土豆有皮和内肉组成，真的不知皮和内肉之间有一层边缘，而且边缘部分的营养价值更高。我们在吃土豆时，即使舍其肉也不可丢其边缘，切记。 (1) 点拨：由“You will see that the potato has skin，an outside and an inside part”得知土豆由三部分组成。 (2) 点拨：由文中“The outside rim..., is the most valuable part of all”知，边缘部分是最好的部分。 (3) 点拨：由短文最后一句得知。 (4) 点拨：由“Even the skin itself is better for food than the inside”知。 (5) 点拨：整篇短文告诉我们一个很重要的知识，土豆的边缘和皮都比内肉营养价值高，而边缘是最好部分，即土豆的吃法。
