红色预警12月7日18时，北京首次发布空气重污染红色预警（red alert for heavy air pollution），启动了空气污染应急制度中等级最高的措施。

This is the first time Beijing has issued a red alert for smog since 2013 when Beijing adopted an emergency response program for air pollution.这是北京自2013年开始实施空气污染应急制度以来首次发布雾霾红色预警。

▌主要应急措施包括：►suspend classes in all elementary and middle schools, kindergartens and extracurricular training schools;所有的中小学、幼儿园、少年宫及校外教育机构停课；►cars are allowed on the roads on alternating days depending on the odd or even numbers of their license plates;机动车将依据汽车尾号实施单双号限行；►outdoor operations of construction sites are banned and some industrial plants are required to limit or stop production.工地停止室外施工作业，同时一些工业企业也要按要求采取限产或停产措施。

▌怎样才能启动红色预警？►Four-tier alerts - blue, yellow, orange and red - will be issued on "heavy pollution" days. Red alert, the highest, will be issued for heavy pollution that is expected to last more than three days.在空气重污染情况下将会发出预警，霾的预警级别由低到高分别为蓝色、黄色、橙色和红色四个等级。

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?。

China's rich make plans to avoid smog越来越多富人为躲避雾霾移民By the 1970s, Central Park was in a state of decay. Bridges were crumbling. Meadows had dried up. Graffiti and vandalism blighted playgrounds and benches. There was an overwhelming feeling that its best days had passed. "Positive use had increasingly been displaced by illicit and illegal activity," is how the Central Park Conservancy describes it today.早在上世纪70年代以前，纽约中央公园还是一片颓败之象。

桥梁摇摇欲坠，柳树也枯萎了。

涂鸦和肆意破坏令游乐场和长椅一片狼藉。

这种景象会让人不由自主地认为，美好的时光一去不复返了。

“正面利用已逐渐被违法活动所取代，”纽约中央公园保护协会（Central Park Conservancy）如此形容道。

Then George Soros stepped in. Frustrated by what he and others saw as New York City's inept management of the 160-year-old institution, Soros and another financier commissioned a study on potential fixes. Its chief recommendation was creating a private citizen-based board to oversee an individual running the park's operations -- in effect, allowing private citizens to control the park. Soon the not-for-profit Central Park Conservancy was created, and the area returned to its former glory. Thirty years later the conservancy provides 75% of a nearly $60 million annual park budget and is a New York institution unto itself. The board of trustees includes former J.P. Morgan (JPM) Chairman and CEO William Harrison, KKR's (KKR) Henry Kravis, and the hedge fund manager John Paulson, who two years ago announced he would give $100 million to the conservancy, the largest park donation ever.后来，乔治•索罗斯站了出来。
