Is the world really going mad? The other
day I was sitting in a small restaurant 41 a quiet drink and
a talk with a few friends, when it suddenly 42 me that
almost everyone in the restaurant was smoking. It wasn't long 43 the
whole room was filled with smoke. I asked with an apology for permission to
open a window to stop myself
44 !
Nowadays air pollution is something that we
hardly question any more. However, I still can't walk down the streets in any
of the big cities without 45 that people are suffering from
the air pollution. It is time for the government departments the world over to
introduce emission(废气排出)controls on all cars and 46 the public transport
system(公共交通体系)to encourage people to 47 their
cars at home. A friend of mine takes flying lessons each morning and it really
makes him 48 when he climbs above the smog layer(烟雾层)and looks down 49 it and thinks:"I'm
breathing that!"This kind of 50 results from the bad
management of resources. Waste things can, 51 should, be
treated properly. Housebuilding, road construction and industrial development
are all earth-moving(or earth-reducing)operations and can change the balances
of 52 created over millions of years. I would like to 53 serious
studies done on all these main works before they are built. Also, there should
be 54 national parks set up to keep the most beautiful parts
of our countries in their natural 55 .
