【思路点拨】
Dear Mayor,
The air is polluted seriously in our city. And it gets from bad to worse because of the increasing number of private cars. Especially during the rush hours, too many private vehicles move slowly on narrow roads, emitting a large amount of waste gas. Moreover, the poisonous gas sent by the nearby factories is also one of the main causes of pollution.
【参考范文】
More and more people have realized the importance of protecting the environment. It’s our duty to protect it. In my daily life, I usually ride a bike or walk to school. I always throw litter into the bin. I will make an effort to keep our public places clean. In our school, many trees are planted to improve the air around us. But it is not enough. Therefore, it’s demanded that immediate and effective measures must be taken to restrict private cars. Public transportation must be developed to the largest extent. Besides, we should use renewable and clean energy recourses.
In a word, I hope the problem will be solved in the near future. Let’s take action now.
Best wishes!
Yours sincerely,
***
