There is some water in a bottle(瓶子) near a big rock (岩石). A bird comes to the bottle and stands next to it. He wants to drink some water, but he can't. Because the neck of the bottle is very long. He thinks and thinks and then flies away (飞走). After some time, he comes back with a small stone (石头) in his mouth. He puts the stone into the bottle. He flies away and flies back again and again. He puts many stones into the bottle. The water in the bottle comes up to its neck and he can drink water. He is very happy.
