话题表达
One possible version：
The fable describes a fight between an elephant and a monkey. Both of them think they are more talented than the other. They ask a bird to decide who is better. During their task of picking fruit opposite the river， they help each other and realize that everyone has his own strength and weakness. The fable tells us that only by cooperating with each other can we do the things well by making use of our strength and avoiding our weakness. So in our daily life， no matter what we do， we should learn from each other and work together to do a good job.
