16.A baby snail(蝸牛) asked his mother,"Why was I born with a shell that grew so hard and heavy?" His mother said,"Because we don't have bones to hold us up.We can only move slowly,so we have a shell to protect us." The baby snail asked again,"The caterpillar(毛毛蟲) has no bones,either,and she can't move quickly.Why doesn't she have a shell?" The mother snail answered,"That's because a caterpillar will become a butterfly.She can fly high into the sky.The sky can protect her." The baby snail had another question,"But the earthworm moves like us.He has no bones and he won't turn into a butterfly.Why doesn't he carry a hard and heavy shell?" "Because he can dig a hole and hide under the ground,and then the earth can protect him." The baby snail then cried,"We're so poor!We have no protection from the sky or the earth!" The mother snail smiled at him,"That's why we have a shell.We don't depend on(依靠) the sky or the earth for protection.We depend on ourselves."
