网友回答

(答案→)Ladies and gentlemen, 
解析：这是一篇发言稿，所以在语言的使用上要大众化，动笔前，一定要认真分析要点，理解要点要表达的含义，不能遗漏要点，跑题偏题。话题是雾霾 (frog and haze) 对身体和生活造成的不良影响。
建议民众和政府分别采取哪些具体行动来维护空气质量。本作文中给出的要点比较简略,故需要充实文章内容，需要注意不要偏离文章中心。写作时注意准确运用时态，上下文意思连贯，符合逻辑关系，尽量使用自己熟悉的单词句式。还要用适当的关联词把句子串联起来，使文章更加连贯。平时除了加强词汇积累，写作联系以外，还可以适当记忆一些类似的范文，这样在考试中可以起到事半功倍的效果。
【亮点说明】The ponents that make up haze may have negative effect on people's health especially that of children and the elderly. 这句话有定语从句和that的用法，Also not excluded are those who have certain diseases Workers working in the open air have a high risk in their health.这句话是倒装句， One of effective solutions to help deal with haze is to make some chemistry changes during the manufacturing process,which could reduce harmful emissions  produced by manufacturing operations这句话有不定式做表语，which引导的定语从句和过去分词做定语。
