Most of us have ever imagined the life on a desert island. We sometimes imagine a desert island to be a sort of paradi se(天堂) where the sun always shines. Life there is simple and good. Ripe fruit falls from the trees and you are free to sit arou nd without any work. This is really a beautiful picture,isn't it? However,the other side of the picture is quite the opposite. Life o n a desert island is awful. You either starve to death or live like Robinson Crusoe,waiting for a boat which never comes.
Perhaps there is some truth in both these pictures,but few of us have had the chance to find out. We can only experienc e it in the story like the following.
