Last Saturday evening， all my family had dinner in a restaurant. We enjoyed ourselves while we were at table. However， some teenagers sitting beside our table began to talk and laugh loudly. What’s worse， they began to smoke， which made us angry. After a while， I stood up and advised them to stop smoking and behave themselves well. But they didn’t follow my suggestions. Instead， they laughed at me， saying that I was too young and too naive.
　　In my opinion， it’s wrong to do like that in public. The future of our country lies in teenagers， who should not only obey the rules in public but also make contributions to the society.
　　上周六晚，我們全家人去餐馆里吃饭。我们吃得很开心。但是坐在我们身边的几个年轻人开始高声谈笑，而且还开始抽烟，这使我们有点生气。过了一会儿，我站起来建议他们不要吸烟并且要规范好自己的行为。然而他们不但不听从我的建议，反而还取笑我，说我人小什么都不懂。
　　在我看来，在公共场合那样做是不可取的。年轻人是国家的未来。年轻人不仅应该遵守公共秩序，还要为社会做贡献。
