　　Recently，the air quality in China has raised a widespread concern.As is indicated in the picture，an old man and his grandson are taking a walk in the street with masks covering their mouths.As the haze is becoming heavier and heavier，they find it hard to see the buildings and trees around them clearly.

　　The picture conveyed here is that air pollution is quite severe in China.Many factors account for this phenomenon.In the first place，vehicles sending large quantities of poisonous gases are a major source of air pollution.Furthermore，factories that release a great deal of smoke are also responsible for the poor air quality.Besides，burning materials like coal or oil for

　　homes and offices is another major contributor to air pollution.

　　Personally，to better the air quality，the government and the common citizens should make joint efforts.Riding and walking are wise options for public travels.Meanwhile，effective laws are supposed to be made to guarantee good air quality.
