范文：
Recently, the documentary Under the Dome aroused wide public concern about smog. It has hit many places of our country, which causes social unrest and contributes to many diseases.
When it comes to smog, the reasons are not far to seek. One of the primary factors that account for the problem is industrial pollution, which is seemingly unavoidable but also controllable. Another factor to mention is traffic emission that is given off by numerous motor vehicles. To make matters worse, not fully understanding this terrible situation, most people have no intention of changing their lifestyle.
Faced with heavy smog weather, our government should take action to control industrial pollution as well as the number of private cars. As ordinary people, we should enhance the awareness of environmental protection and lead a green lifestyle to make the sky bluer.
最近，柴静的纪录片《穹顶之下》 ( http: / / www.21cnjy.com )（Under the Dome）再次引发公众对雾霾的广泛关注。请就此主题为学校广播站写一篇100-120词的通讯稿。
内容要点如下：
1.雾霾的危害和影响；
2.雾霾的成因（工业污染、尾气排放）；
3. 提出你的建议。
