雾霾，是雾和霾的组合词。雾霾常见于城市。中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报，统称为“雾霾天气”。
雾霾是特定气候条件与人类活动相互作用的结果。高密度人口的经济及社会活动必然会排放大量细颗粒物（PM 2.5），一旦排放超过大气循环能力和承载度，细颗粒物浓度将持续积聚，此时如果受静稳天气等影响，极易出现大范围的雾霾。
关于雾霾的解决方法
爱上海同城Dear David,
I’m glad to receive your letter. I have learned from your letter that you are concerned about the smog which frequently appears in some areas of China. Thank you for your concern. I’m also very worried about such terrible weather because it has brought much inconvenience or rather harm to people’s health such as traffic jam, road accidents, bad coughs, throat hurts and ever lung cancers and so on.
As everybody knows, a good environment comes from good protection. So we should do what we can to make a difference. Try to drive less and choose air-friendly products. Only when everyone has the environmental awareness can we have cleaner air.
爱上海同城Hoping to hear from you soon and share your good ideas.
关于雾霾
爱上海同城Since the winter last year，the haze has occurred a lot of times.Haze is air pollution in which is mixed up with dust， smoke and other dry particles ，and it obscure the clarity of the sky and interacts with the natural environment.This kind of air pollutant come from a variety of natural and manmade sources. Natural sources can include windblown dust， and soot from wildfires. Manmade sources can include motor vehicles， and industrial fuel burning， and manufacturing operations. The one of the main cause that touches off haze is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air become air pollution.
it has done great harm to our daily life.many traffic accidents happened just because of the heavy haze weather，more and more people have to go to see the doctor because the serious disease caused by the haze，quite a lot of flights have to be put off，a great number of people have to stay at home for fear of the poisonous air caused by the haze.
爱上海同城People have realized the great harm caused by the smog and the importance of protecting the environment.people all over the country are taking measures to reduce the smog weather.the government suggests people go to work or school with the public traffic， such as the bus and the underground.Also we should plant more trees.One of effective solutions to help eliminate haze is to make some chemistry changes during the manufacturing process，so it could reduce harmful emissions which are produced by manufacturing operationsAccording to me， I will go to school by bike or on foot， and I won’t throw the waste anywhere.in addition， I will tell the people I meet to protect the environment as possible as they can.would you like to tell me some good ideas？i’m looking forward to your reply. We are all in this together！ We shall survive and thrive together！
关于雾霾
Dear Mike，
Thank you very much for your concern. Last months several places in Beijing were blanketed with thick yellow fog. Everything around disappeared from oursight. Some highways were closed. Traffic jams were commonly seen in the streets. Many people, especially children and seniors, even found it difficult to breathe. As a result, local hospitals were crowded with people who had problems with their noses and lungs. Part of the cause was the dry weather, but the severely damaged environment contributed a lot to this nightmare. Personally I didn’t get any health problems in the haze because I stayed mostly indoors.But to make a significant change we really have to do more to protect our environment. To live a better life we have to push on with the economy, but it wound be meaningless if we have to achieve it at the cost of our breathing air.
Regards!
Yours，

爱上海同城As people are knowing more about PM2.5, they are becoming more and more concerned about their living environment. As students, what should we do?
爱上海同城First, we should ride bikes or take buses to school. Riding bikes is also good for our health. We should try our best to advise our parents to drive less. Try to walk or ride bikes to work. Second, we’d better use both sides of the paper. Don’t waste paper. Third, we should save power. Remember to turn off the lights when we leave the classroom. At last, we should plant more trees and flowers.
If everyone makes a little effort, the world will be more and more beautiful.
