I think everyone have done or will do a good deed . some one do it of his own free will while others are forced to do it . Do you think we should expect a reward when doing a good deed ? Different people have different opinions towards it . Some people think we should get a reward . It is equal to give and receive . Just like a smile , if you help some one , he smile to you ,I think you will feel happy . However , many people think we should do good deed without reward . If you do a good deed , you will feel satisfaction . In other words , you do these things of your own accord ,you will be happy although get nothing . In my opinion , we should not expect a reward when doing a good deed . In fact , although others don’t give us something , we can get something significative . 本文来源：https://www.wddqw.com/doc/e505c6e219e8b8f67c1cb988.html
