Air Pollution
It is reported that thick fog and haze surround many parts of China. People have to wear masks when they go out.As air pollution is getting increasingly worse,it has become the main concern of people.
Air pollution can have serious consequences for human’s health and also severely affects natural ecosystems. Millions of people die of illnesses related to air pollution every year.Due to particles from exhaust emissions,green house effects result in warmer weather,acid rains corrode the earth,and frequent haze causes traffic problems.
Confronted with such situation,positive measures should be adopted. The government should keep its regulatory role for properly supervision. Related rules should be made out for reducing emissions of new vehicles and limiting high-emission vehicles.Factories should meet standards for curbing emissions of pollutants in surrounding cities.Meanwhile, provinces and municipalities in each target region should set up a mechanism for the joint prevention and control of air pollution.
【點評】
文中從霧霾和人們帶口罩出門引出空氣污染這一話題，然后在第二段中談及空氣污染對人類健康和自然生態(tài)系統(tǒng)的影響，在最后一段中分別指出政府，工廠及省、市等需要采取措施解決空氣污染的問題。
第一段中thick fog and haze意為“霧霾”，getting increasingly worse意為“日益惡化”;第二段中severely affects natural ecosystems意為“嚴重影響自然生態(tài)系統(tǒng)”，exhaust emissions意為“廢棄排放”，green house effects意為“溫室效應”，corrode意為“腐蝕”;第三段中keep its regulatory role意為“發(fā)揮其監(jiān)管的職責”;curbing emissions of pollutants意為“減少污染物的排放”。
