First of all , what is smog?
The term "smog" was invented to describe the combination of smoke and fog experienced by the city of London in the early 1900s. Modern smog, however, is typically formed by chemical reactions in the lower atmosphere. This is known as photochemical smog. Smog is a combination of fog and haze.

关于雾霾的英语PPT讲稿
Hello，everyoneGood morning！My name is Xiao Weihong,I’m from Sichuan province.And today,my topic is Fog and haze.This is my name,and this is my student number.From this you can know that my topic is about 5 parts,and now,we look at the first part--Definition.Long long ago,we climb with our hands,as time goes by,We are walking upright.But the environment turns bad,we live in a world which is full of poison.In recent years, air pollution has already become one of the biggest environmental problems in China. Thick haze has blown off the coastal areas.So,what is haze?It’s a combination of little drops of water and tiny particles. For better understanding of this noun.Now,we should know another word--PM.It means particulate matter.It also means a small discrete[dɪ'skrit](离散的) mass of solid or liquid matter.So,we can easily know what is PM2.5.It means particles can be drawn into lung[lʌŋ], which diameter is less than 2.5 micron.We often pay our attention to PM2.5，because the number of 2.5 is very important ,if the diameter of particle is bigger than 2.5 micron,it will be stopped by our nose and will not go into our lung. But ifthe size of particle is less than 2.5 micron.It harms us most.So, wether['wɛðɚ] our weather['wɛðɚ] is good is determined by the number of PM2.5.Look at this picture,if the number of PM2.5 of per unit volume is less than 50,we say the air quality is good.if the number is between 50 to 100,we say the air quality is moderate.But if the number is between 151 to 200,we call it unhealthy.and if the number is above 300,we think it horrible.As we know,many places of China is even above 400.So,it’s very dangerous.Now,let’s look a historical event.London smog!Let’s know about it.First,we watch a short video.(I don’t know wether the computer can paly it) Ok,from this short video we can see a black world full of smog.So,what happened in London?In 1952, London smog happened,and it lead to 12000 people died directly or indirectly.In 1954 ,London launched a special act of pollution.After 4 years later,smog happened again,and 1200 people dead.Only after 1965,the toxic smoke was vanished.In 1968,Britain enacted the Clean Air Act.And until 1980, the fog day has been reduced to five days one year.It took about 30 years to solve the problem.So,from this accident,we know thatonce the fog happened, it will be hard to solve it.How about our situation?First,Let’s look some pictures.There’re two contrast figures.The upper left corner is a picture of beautiful scenery,it’s clear,but the one at the lower left corner looks terrible.And the top right one is the map of our country which looks pretty,but from this one we can see nothing except haze.How about this one?Oh,it’s a man who wears a respirator['rɛspəretɚ] is riding a bike in the endless smog.And again,this picture tells us a man is riding a bike in the road.It’s dangerous because it’s hard to see far. The last one,it looks beautiful in some degree.But like mushrooms,the more beautiful the more toxic it is.In fact,it’s very terrible.So,what caused our country to be this situation ?These several reasons are we recognized.First,burning of fossil fuels in vehicles.As we know,the number of cars in our country is increased rapidly.so ,the demand of fossil fuels is increased fast,too .Second,in our country the power plants still rely on fossil fuels. It contributes to air pollution mostly.Third,various industrial processes are existed everywhere.Their emissions of waste polluted the air.Therefore,it’s time to take some measures to change the situation .So, what should our government do? Firstly,our government should strengthen air monitor to know the the actual situation.Secondly, government should enact more strict laws and regulations in order to reduce the sources of pollution.Thirdly,government should regulate people 's daily action and the industrial stly,our country should help develop green and energy-saving energy.Only do these can our country become beautiful again.For an individual,what should we do to reduce the harm of haze?First,if conditions permit,we can wear a respirator which can help us perhaps not much.Second,if we go out ,we should try to take public transportation.Third,hybrid['haɪbrɪd] cars should be regarded. Four,clean energy should be promoted in our daily life.In the last,the public supervision is important. Not only the role of government, but must have the personal effort.Only do this can we have a better tomorrow.So let’s do something from now on.=============================================== =============Thank you,yes,it dose harm our body.as i have saidbefore,the PM2.5 will go into our lung though our respiratory['rɛspərətɔri] tract.Long-term effects can damage respiratory defenses.Particles can cause the loss of the body's immune function.Thank you!yes ,this is a question that we all care about.But as i said before,the haze is the result of long-term development.and I think it will not disappear totally in recent years.But if our government take more actions on the problem,it will be vanished faster than we expect.1.As you have said that we live in a world of haze ,will it cause any harm to our body?2.when do you think the haze will be vanished?。

Automobile exhaust
Automobile exhaust is another important cause of smog. The exhaust emissions from automobiles contain a large amount of pollutants such as hydrocarbons, nitrogen oxides, and carbon monoxide. These pollutants react chemically with oxygen in the atmosphere to form secondary particulate matter, which in turn leads to the generation of haze.

Haze contains hazardous particles that can enter the bloodstream and damage the cardiovascular system, increasing the risk of heart disease and stroke
