[不定项选择题]共用题干 The Smog(烟雾)

For over a month,lndonesia was in crisis.Forest fires raged out of control as the
country suffered its worst drought for 50 years.Smoke from the fires mixed with sunlight and
hot dry air to form a cloud of smog.This pollution quickly spread and within days it was
hanging over neighbouring countries including Malaysia,Singapore and Thailand.
When the smoke combined with pollution from factories and cars,it soon became
poisonous(有毒的).Dangerous amounts of CO became trapped under the smog and
pollution levels rose. People wheezed(喘息)and coughed as they left the house and their
eyes watered immediately.
The smog made it impossible to see across streets and whole cities disappeared as
grey soot(烟灰)covered everything. In some areas, water was hosed(用胶管浇)from
high-rise city buildings to try and break up the smog.
Finally,heavy rains,which came in November,put out the fires and cleared the air.
But the environmental costs and health problems will remain.Many people from South-
Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes(汽车
排放的废气)and factory pollution. Breathing problems could well increase and many non-
sufferers may have difficulties for the first time.Wildlife has suffered too.In lowland forests,elephants,deer,and tigers have been driven out of their homes by smog.
But smog is not just an Asian problem.In fact,the word was first used in London in
1905 to describe the mixture of smoke and thick fog.Fog often hung over the capital.
Sometimes the smog was so thick and poisonous that people were killed by breathing
problems or in accidents.About 4, 000 Londoners died within five days as a result of thick
smog in 1952. Indonesia was in crisis because of the drought.

B.Wrong
