This morning I went to the classroom at seven o'clock because I was on duty today. Of course I was the first one. I was cleaning the blackboard when Li Ming came into the classroom. I asked her, "Who do you come here so early?" She answered with a smile, "I know you are on duty today. Let me help you." I was very happy and said, "Oh, thankyou. " We began to work together. When the teacher arrived, we had already done a good job, and the classroom was clean and tidy. The teacher praised me.
The day after tomorrow Li Ming will be on duty. I am going to help her too. We are good friends. We should help each other.本回答被网友采纳
