短文改错题。One Sunday last month I go shopping with my friends. Luckily in a crowded store, I had my wallet losing. I was such upset that I almost shouted. I was afraid to tell to my parents the truth. So I went back to school without some money. I didn’t know what to do next. I didn’t eat anything Monday. My roommate Mary found something wrong with me but she asked me about the problem. I told him the truth. Then Mary lent me some money, with that I lived through the terrible week.
