classmates in the People's Square.Suddenly when we were having a good time ,we saw

to help him.So my friends ahd i were going to hold him across the street .
Finally the old men crossed the road successfully ahd he had being thanking us all the time .
Tired but satisfied,we were enjoying a wonderful time last Sunday moring .
总觉得这篇作文写过去的事用过去式比较好,过去进行时有点怪怪的
鄙人 写的不好 还希望可以采纳
