阅读理解。 One day, a little monkey and a little fox went out to play. They saw an apple tree on the other side of the river. There were many big and red apples on it. But there was no bridge over the river. The monkey thought hard and had an idea. They pulled down a tree and put it over the river as a bridge. The monkey said, 'My old friend, you go there first.' But after the fox went to the other side, he kicked (踢) the tree into the river and ran to the apple tree. 'How can I get there without the tree?' cried the monkey. The fox laughed and said, 'You just stand there and watch me eating the apples.' The monkey was very angry. Suddenly it began to rain. The water level (水位) in the river rose (上涨) and tree flew away with the water. 'You can eat all the apples. But you can't come back,' shouted the monkey.
