?? According to the Chinese Academy of Science,driving car and burning coal are two main reasons.People have been told : Don’t do outdoor sports;If you have to go out,wear a mask; wash your face and clean your nose as soon as you get home.

People have realized the great harm caused by the fog and haze and the importance of protecting the environment.People all over the country are taking measures to reduce the fog and haze weather.The government suggests people go to work or school with the public traffic, such as the bus and the underground.Also we should plant more trees.

One Sunday , Cody decided to go sailing in his boat with his friend Dane , but Dane happened to be away. Dane’s brother Brett wanted to go instead though he did not know anything about sailing. Cody agreed and they set out to sea.

Soon they found themselves in a thick fog. Cody was sure they would be hit by a big ship. Fortunately（幸运地）he saw a large buoy（浮标）through the fog and decided to tie the boat to it for safety. As he was getting onto the buoy , however , he dropped the wet rope. The boat moved away in the fog carrying Brett who did not know how to use the radio. He drifted（漂流）about and was not seen until twelve hours later.

Cody spent the night on the buoy. In the early morning he fell asleep and was having a bad dream when a shout woke him up. A ship，the Good Hope，came up and he climbed onto it and thanked the captain. The captain told him that Brett had been picked up by another ship and the ship’s captain had sent out a message.

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?

2.How did the air in London become much cleaner?

A．There was not so much fog in the winter later．

B．A law was made to keep people from burning coal in their houses．

C．Many factories in the city were closed．

D．People paid more attention to cleaning their city．

3.What does the underlined work “pea-soupers”refer to?

A．Smog????? ????????????? ????????????? B．Smoke????? ????????????? ????????????? C．Gas?????? ????????????? ????????????? D．Coal
