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.

在我的家鄉(xiāng)，空氣污染十分嚴重。然而，近幾年內(nèi)，由于私家車數(shù)目的增多，空氣污染變得更加糟糕。特別是在交通高峰期里，有太多的私家車在狹窄的道路上慢慢的移動，釋放出大量污染氣體。此外，附近工廠排放的有毒氣體也是主要污染源頭。因此，這要求采用直接有效的措施來限制私家車，最大限度地開發(fā)公共交通。而且我們還應使用干凈、可持續(xù)的能源。
