导语：空气污染是当今世界的主要问题之一。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!
Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations.
Automobile， trains， planes and busses need energy， too. Nearly all of this energy is produced by burning fuels. The burning produces wastes， some of which remain in the air， causing air pollution.
Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities.
They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime， many power plants are being modernized to give off less polluted material.
Also， engineers try to design and locate new power plants to do minimum damage to the environment. However， it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution.
There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
【参考译文】
空气污染是当今世界的主要问题之一。在现代化工业国家中，办工厂需要大量的能量。
汽车、火车、飞机和公共汽车需要能量，太。几乎所有这些能量都是由燃烧的燃料产生的。燃烧产生的废物，其中一些留在空气中，造成空气污染。
科学家们正在寻找办法来阻止空气污染，尤其是在大工业区和人口稠密的城市。
他们正在研究新的发电方式，这种方法对环境的破坏性更小。与此同时，许多发电厂正在现代化，以减少污染的物质。
同样，工程师们也正在努力设计新的发电厂，确定新的建厂地点，把对环境的危害减少到最低限度。然而，在我们拥有一个“干净”的世界之前，我们还有很长的路要走。几乎所有的国家都在努力防止和控制空气污染。
环境保护主义者的任务似乎没有尽头。人们会不断找到控制污染的新方法。
