[单项选择]The dark smoke that comes out of stacks or from a burning dump contains tiny bits of solid or liquid matter. The smoke also contains many gases, most of which cannot be seen. Altogether, they make up the serious problems of air pollution. In so many places it keeps us from seeing the sun, irritates our eyes, causes us to cough, and makes us ill.
Air pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had "black snow" from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem.
Air pollution can kill babies, older people , and those who have respiratory (呼吸道的) diseases. In London, in 1952, four thousand people died in one week as a result of a serious air-pollution episode. In 1948, in the small town of Donora, Pennsylvania, twenty people died in a four-day period of bad air pollution.
