     when Chinese people find out that someone comes from London, they often say, "London is a foggy city,
isn't it?" British people who visit China often   1   say that London is not a foggy city at all!But if London is not
foggy.    2   bo so many people in China think it is?In tact, London used to be a foggy city,   3   in isn't any
more.
     In London peole of this it in pollution (污染) came from factories, but a lot of it came from coal (煤)
because people used it in their houses   4   warm duing the winter.By the 1950s, Long-don's air pollution had
became so   5   that the govemment (政府) decided to do something to clean up the air. A new rule was made.
It said that   6   was not allowed to bum (燃烧) cosl in any British city. Just a few years  7  , the air became
much cleaner.
      Now many Chinese cities meet the same kind of   8   with air pollution that London met forty or fitty years
ago. However.this problem is more difficult for Chinese cities to   9  . First, more of the pollution comes from
big fsctoies than from coal that pcople use in their houses. If these fac-lories are suddenly closed, lots of
people   10   their jobs.Second, cleaner fuels(燃料)are quite expensive. However, the air in many cities is   11   
slowly becoming cleaner,because the govem-ment and ordinary people are trying to make pollution   12  . As
a result,the air in Beijing is get-ting cleaner and cleaner.
