　　Once when I was six years old，I saw an amazing picture in a book called True Stories from Nature about the primeval forest.It was a picture of a boa constrictor(大蟒蛇) in the act of swallowing an animal.In the book it said："Boa constrictors swallow their prey wholly without chewing it.After that they are not able to move and they sleep through the six months that they need for digestion."

　　I thought deeply then over the adventures of the jungle.And after some work with a colored pencil，I succeeded in making my first drawing，my Drawing Number One.I showed my work to the grown­ups and asked them whether the drawing frightened them.But they answered: "Frighten?
