对社会有贡献的人
Describe a person who contributes to the society You should say:
Who this person is How you knew him/her
What type of work he/she does
And explain why you think his/her contributes to the society
题目解析：
题目要求描述一个对社会有贡献的人。题目中提示我们可以介绍 ta 是谁，你怎么知道这个人的，ta 是做什么类型工作的，你为什么觉得 ta 做的事情对社会有贡献。我们可以补充说明，这个人的年龄，国籍，你第一次听说这个人的时候， 对 ta 的看法是什么，你有没有从 ta 的工作中获益，你对 ta 的工作有何看法。这道题的思路比较好想，其实任何一个工种，都给社会上的其他人提供了相应的服务和贡献，如清洁工凌晨打扫街道，给上学上班的市民提供整洁的通勤环境； 早餐店的老板每天早起做美味大碗的早餐给大家吃；大学教授发表论文，分享研究成果，上课培养学生等等。
Sample Answer：
This topic reminds me of my next-door neighbour, David, who's been working as a photojournalist for over five years in a local press.
I got to know him when my family moved to this community roughly a decade ago. We soon got along as both of us are fanatical about taking photos. We used to go on excursions together and capture the wonderful unspoilt scenes with our digital cameras. He's the sort of person who has an insatiable curiosity about everything, I can tell this from those books he read and pictures he shot. You know, he's got a passion for life.
Anyway, after graduating from Uni, he soon joined a local newspaper office and became a photojournalist. Unlike correspondents who report things with words, David tells visual stories with expressive images. The subject matter varies greatly, I mean, he has taken pictures from national events like G20 summit, to everyday issues happening at a local level. So I think his job is of great fun. But he once told me that, being a photojournalist, you need to remain silent as you move in the background. You should observe attentively, but when there's an emergency, you run towards it immediately, camera in hand. That sounds challenging, but truly rewarding.
I think this job is significant to the society. If we had no photojournalists in the world, those true stories wouldn't have a chance to be brought to life with powerful pictures. I would say people like David are still shaping our understanding of major events and trivial daily stuff via their cameras, even though we might even know who they are. In all, they're like unsung heroes to me.
