    Jim,Tom and Jack are three little birds. One day, their mother says to them,“Boys,it’s time for you to fly down and eat sand (沙子).” Jim and Tom do, but Jack says, " I can't fly, and I don't like sand. " "But you have to, " the mother says. "Birds have no teeth. We must eat sand because it can help us grind up (研磨) some hard food." But Jack is disobedient (不服从的). He just cries, "I can't fly, and I don't like sand."
