In my hometown, the air is polluted seriously. However, in recent years, the pollution 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. Therefore, it’s demanded that immediate and effective measures must be taken to restrict private cars and public transportation must be developed to the largest extent. Besides, we should use renewable and clean energy recourses.

在我的家乡，空气污染十分严重。然而，近几年内，由于私家车数目的增多，空气污染变得更加糟糕。特别是在交通高峰期里，有太多的私家车在狭窄的道路上慢慢的移动，释放出大量污染气体。此外，附近工厂排放的有毒气体也是主要污染源头。因此，这要求采用直接有效的措施来限制私家车，最大限度地开发公共交通。而且我们还应使用干净、可持续的能源。
