练习材料：L12(1)：Life on a desert island
Most of us have formed an unrealistic picture of life on a desert island. We sometimes imagine a desert island to be a sort of paradise where the sun always shines. Life there is simple and good. Ripe fruit falls from the trees and you never have to work. The other side of the picture is quite the opposite. Life on a desert island is wretched. You either starve to death or live like Robinson Crusoe, Waiting for a boat which never comes. Perhaps there is an element of truth in both these pictures, but few us have had the opportunity to find out.
