I went shopping with my wife.We have a lot of things to (have改成had ) 时态前后统一,过去时
buy them.we drove to the center of the city and stopped( 去掉them)多余的词,和前面a lot of things重复了
our car in front of the shop.An hour late,we came back(late改为later )
to the car.And it was stramge that we couldnot open(去掉and或者改为But,stramge应该是strange )
the door.So we asked policeman for help（这里应该是个断句吧,少了个句点“.”我默认你是打错了） He was glad to help him.After a few minutes,he got the door open.(him改为us )帮助“我们”
Just then a man came up and shouted angry."what are ( angry改为angrily)用副词修饰动词
you doing with my car?" we were surpising and went to (suprising改为suprised )受到惊吓,被动
see the number of the car.what you think we did then （what 和you中间加上do）?没有助动词的问句
你的短文里打字错太多,大小写不分,有些地方不知道是你打错了还是原文就这个样子.能改的基本都改正了.你自己再对照一遍吧.
