It is hot day in summer. A lion is walking along a lake. He is looking for something to eat. He is very hungry. A duck is swimming in the water. The lion is very happy to see him. "Aha. There is my lunch," the lion says to himself（自言自语）. "Hello, Mr Duck!" "Go away, bad lion!" says the duck. "I have good news for you." "What is it?" asks the duck. "I don't want other animals to hear it. Please come here, "says the lion. The poor duck gets out of the water and runs to the lion. The lion catches him and eats him up.
