再答： Air pollution is one of the major problems of the modern world.Scientists are finding ways to stop air pollution especially in big industrial areas and some big 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. 　 Measures have been taken to control pollution. In recent years, legislative steps have been introduced to control pollution. Rivers are being cleaned. Air is purified, and pollutants are being trapped before they are poured out of chimneys. 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. 翻译： 大气污染时当今世界最主要的一大问题。科学家们正在积极寻找阻止空气污染特别是工业城市的空气污染的方法，正在研究能产生电能但对环境污染相对较小的新方式。同时，许多发电厂都被换代升级，以减少污染物的排放。 为了防止污染，采取了一些措施。近年来，采取一些立法措施来控制污染。河水正在变清，空气正被净化，污染物从烟囱中排放出来以前，就得到了控制。 然而，在我们能够拥有一个干净的世界之前，我们仍需要走很长的路。几乎所有的国家都在试图阻止并控制空气污染。人们会继续努力寻找新方式以控制大气污染。
