　　 Air Pollution
　　 We all know that clean air is important to good health. Wherever you go and whatever you do，you are always surrounded by a sea of gases that we call air. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities.
　　 Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into the air. Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases.
　　 Our country is trying hard to prevent and control air pollution. As long as every citizen realizes its importance and makes joint efforts, the day will come soon when people will take in only clean air. Then, the sunlight will no longer be blackened out by smoke and soot.
　　 空气污染
　　 我们都知道，清洁的空气是非常重要的身体健康。无论你走到哪里，无论您做什么，你总是由多种气体，我们称之为气海包围。如果有空气中的杂质，它们可能是我们的身体所吸收，使我们生病。我们需要清洁的空气，但不幸的是，空气污染是全球目前，在城市尤其如此。
　　 许多大城市也不是无污染。我们的城市有很多工厂，我们需要食物，衣服和其他东西。这些工厂每年倒在空气中的烟雾进入亿万吨。发电厂和房屋燃烧煤大大增加了空气污染。此外，在城市有更多的汽车了。一旦出了街头，他们将在清新的空气和有毒气体取代它。
　　 我国正努力防止和控制空气污染。只要每一个公民实现其长期的重要性，使双方的共同努力，这一天将很快来到，当人们将在只有干净的空气。然后，阳光将不再由烟雾熏黑和烟尘。
