口语考试what do you think is a good heart?谁能帮我解决一下,帮我写一段,就一分钟时间!

My understanding of "good heart" I always wonder the real meaning of being a good person.There is no doubt that a good person must have a good heart. He is ready to help people all the time.When someone turn to him for help,he will try his best to help him.However,what I want to say is before we go to help others,we should know if the thing is really necessary to do.What's more,doing things for them can solve the principal problems. All in all,I think a man who owns a good heart not only help people get out of hard situation,but also make them know the final meaning of the help.
