There are many animals in the forest. Today is a fine day. The animals are having a sports meeting. Monkey, Fox, Panda, Rabbit and Bear are running. Look! Rabbit is the first（第一）. Fox and Monkey are the second. Bear is the third. The other animals are shouting, “Bear! Come on! Bear! Come on!” And look there, Duck and Pig are doing high jump. Pig is too fat, he can’t jump very high. So Duck is the champion（冠军）. Here! Cat and Squirrel are climbing a tree. Cat is ill. So he is the last（最后的）, but he does his best. This sports meeting is wonderful. The animals are very happy!
