- 参考答案：What Can Be Done to Tackle the Haze Problem?
China has been increasingly hit with severe hazy conditions since the beginning of this century. In many big cities, where the pollutants in the air can’t be dispersed without strong wind, the haze problem is worse. As a result, the incidence of respiratory disease among city dwellers has been on the rise.
The cause of the haze is no mystery. With rapid industrialization, many steel and power plants bum a lot of coal. Without resorting to the clean technology, these factories emit smoke and fume directly into the atmosphere. The past decade has also witnessed a surge in the number of private cars. This would not have posed an environmental problem to the cities if the quality of gas is good and the car engines meet the emission standard. With fast-paced urbanization, the sand and dirt released from numerous construction sites also contribute to the haze problem.
In order to tackle this problem, we should reduce the use of private cars and choose public transport. The government should strictly enforce the environmental laws and severely punish polluters. - 系统解析：范文点评：
