A recent study found people's lives are made shorter in North China. It showed the life expectancy(平均寿命) had been cut by 5. 5 years there. Re?searchers think that the heavy air pollution in China should be to blame (承担责任) .It's really the truth. Our government has already done something. How?ever,it doesn't seem to work so well.
"Air pollution in China is doing harm to people's health. The harm is much more serious than we can imagine," said Chen Yuyu of Beijing University,one of the researchers of this study.
Dirty air brings serious problems in North China. In January this year,the air pollution was worse than that in other places. That was caused by rising temperature and waste gas (废气) from coal heat-ing.
Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses,ride bicycles or walk,instead of driving cars. The factories that pollute heavily should be closed.
"We need to improve our environment,al?though it might be expensive. Protecting our envi?ronment means protecting ourselves Li Hongbin,another researcher of the study said.
