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.

现代社会空气污染的一个主要的原因是，现代工业园区的工厂需要大量的能源。

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.

科学家们正在寻找阻止空气污染的方法，尤其是在大工业区和人口稠密的城市的。

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.

,他们正在研究发电的新途径,可以减少对环境的损害.与此同时,许多发电厂正在实现现代化以减少污染物质.

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 aclean world. Nearly all of the countries are trying hard to prevent and control air pollution.

同时，工程师们尝试和找到对环境的损害最小的新型能源。然而，在我们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预防和控制空气污染。

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.

看来环保主义者要做的任务乎没有尽头，人们会不断地寻找新的方法来控制污染。
