London used to be “foggy”（ 有雾的） for the same reason that cities like Beijing or Chongqing are “foggy” today. The “fog” was in fact smog（烟雾）, a mixture of smoke and fog．In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. In a few years, the air became much cleaner. There were no more “pea-soupers”.
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.
1.What was the main reason for air pollution in London?
A．There was too much smoke in the sky．
B．There were too many factories in the city．
C．People burnt too much coal in the houses．
D．The city was too big for the cleaners to clean．
2.What does the underlined word “pea-soupers” refer to?
A．Smog B．Smoke
C．Gas D．Coal
3.Which sentence is Not true?
A．Air pollution is serious in Beijing and Chongqing．
B．Using coal is much more expensive than using gas．
C．Factories made much more pollution in China．
D．The reasons of air pollution in London and Beijing are different
