A little monkey and a little fox (狐狸) were friends. One day, they went out to play near a river. They saw a(n) 

1 tree on the other side of the river. There were many big and red apples 2 it. But there was no bridge over the river. The monkey and the fox thought hard and finally they had a(n)3 . They pulled down (拉倒) a small tree and put it over the river as a bridge.

The monkey said, "My dear friend, you go first."4 after the fox went to the other side, he kicked (踢) the tree into the river and ran to the apple tree. "How can5 get there without the tree?" shouted the monkey. The fox laughed and said, "You6 stand there and watch me eating the apples." The monkey was very7 .

Suddenly it began to rain. The water level (水位) in the river rose and the tree went away with the water. "You can8 all the apples. But you can't come back," shouted the monkey.

The fox stopped eating and9 the monkey sadly. He realized he was10 . He shouldn't have only cared about himself.
