2009全国中考英语试题汇编试题(55)写作:雾霾天气（haze weather)

Recently, the haze weather has happened to many cities in the north of China. It brought people so much trouble. For example, the haze weather made people cough. More accidents were caused because drivers couldn't see clearly in such haze weather. Outdoor activities in the haze weather were not good for peoples health, so schools had to stop PE classes. I think we must do something to avoid this kind of weather. We should use public transportation more. We can choose to walk or ride bikes instead of driving cars. Planting more trees is necessary, too. If we make less pollution, we will have a better world to live in.
