    Everyone needs help.Often there are some cases that we help ourselves indirect in helping others.Last month, Tom asked for me to help him with his math.In order to help him,I go over the textbook again and again,and did lots of exercises.To his surprise,some difficult problems that I could not understand before worked out by myself.After a month,with my help,Tom made great progresses in math,too.Such a experience enabled me to realize that help others also does good to ourselves.So when others is in trouble,never hesitate to help them.
