who can tell me if there is any problem in the following passages? thank you very much!
Once I see the question, I think about the interesting story happened when I was a child which I want to share to you. When I was elected as the monitor in grade one, I was very happy because that was the first time I was trusted by others. Then the teacher asked me to have two or three students help cleaning the playground. However no one would like to do. So I’ll give candy to those who will do the work. So I find three students. Think of it carefully, it was an motivate mechanism, wasn’t it? We need to motivate our staffs.
