Pollution: An Increasing Concern in China　　It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc.　　To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. Whats more, the media should play an important role in implanting a sense of environmental consciousness into peoples mind. If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.　　点评：该预测题为社会热点话题，也是四级命题作文经常关注的环境问题，值得引起重视。本文属于解释性说明文的写作，主题是污染。
