London used to be “foggy” for the same reason that cities like Beijing or Chongqing are “foggy” today．The “fog” was in fact smog, 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．Within 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．

The air pollution was so bad in Harbin, in China, on October 21,2013 that the city had to close roads and schools, and cancel* hundreds of flights from its airport.
News reports said the smog (a mixture of smoke and fog) was so thick that people couldn’t see more than 10 or 20 metres in front of them.
It is also said that people could not even see the person standing next to them. The city’s website said: “You can’t see your own fingers in front of you.”
The local people said there was a “burning” smell in the air. Many people covered their noses and mouths with scarves or masks*.
The pollution was caused on several factors* including: farmers burning off old corn stalks* and crop stubble*; coal*-fired heating systems; and low winds that allowed the smoke to remain over the city.

Harbin has a population of more than 10 million people. It lies in northeastern China, where cold winter weather can last up to six months. The main fuel* there is coal, because it is cheaper than other types of fuel.
Air pollution from burning coal can cause health problems like heart disease. During the smog crisis* in Harbin, the number of people taken to the hospital with breathing problems was 30% higher than usual.

People and air pollution are often in the same places. This means that cities with large populations have
the biggest problem of dirty air. Air pollution is caused by many different things. A major kind of air
pollution is the gas from cars. Statistics (統(tǒng)計資料) show that 93 percent of all auto trips are within cities.

electricity. Of course, much more electricity is used in the city than in the country.

pollution even worse. Many major industries are also responsible for the dirty air in the around cities. The
fumes (煙) from iron, steel, chemical, and petrol production add particles (微粒) to the air.
The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy
traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may
kill trees and plants and cause metal to corrode (腐蝕). In some of the larger cities, these fumes endanger
the live of human beings by contributing to lung diseases and causing early death.
