范文赏析
（林楚婷 广东实验中学)
用it’s +adj.+for sb. to do sth. 句型承上启下，为下文提出环保建议做铺垫
Dear city mayor,
At present, there are more and more environmental problems in our city. So it’s important for us to start with small things to change the situation.
First of all, we should call on people to develop the habit of travelling with low carbon, like choosing public transport. Secondly, as citizens, we are supposed to keep good living habits in the daily life, such as taking a short shower to save water and turning off lights to save energy. Moreover, we can also organize activities to encourage people to plant more trees to help improve the environment.
巧用衔接词First of all, Secondly及Moreover, 使得文章层次清晰，逻辑严密
In conclusion, it’s high time for everyone to take action to protect our city.
Yours,
Li Hua
