When Oakland High School in California moved into a new building,the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts(專家)came to find the cause of the sickness. Finally,they discovered that the air in the building was not safe to breathe. They were surprised to find out
that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards
(合成板).This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化學物
質). This is just one example of a modem problem that is most common in cities—indoor air pollution(污染).
People have worried about air pollution for many years,and the government has spent lots of money trying to clean
up the air of big cities. But now we found that we are still breathing unhealthy air. A study shows : Indoor air pollution is
almost two to five times(倍)worse than outside pollution. So remember to open the windows and don’t stay too long in
modem buildings with windows closed.
