All of our classmates did voluntary work on the last Sunday.
We cleaned up the park and distributed the food to the homeless people. Mary and John went to the hospital and looked about the sick children and made them happy.
Mary and John donated the clothes to the Children Home.
All of use had a happy day.
过去式，翻译时候要尽量明确时点和时段，一般的一般过去式，更强调某时点，所以翻译时候应注意这样的词语，如last Sunday， yesterday， last Year等等，如I ran 2 km yesterday表示我昨天跑了2km，并且跑的这个动作已经结束。
若没有明确的时点，就是无法确定动作是否完成，通常使用现在完成时，表示过去已经开始做，现在可能完成，或者还有可能继续，如I have run 2 kilometers，只能说明我已经跑完了2km，而不能确定现在是否正在跑。
