英语中我们通常把雾霾说成 haze ，雾霾是由雾和霾组成，雾霾的首要污染物 PM2.5 (Particulate Matter 2.5) 指的是大气中直径小于或等于2.5微米的颗粒物，就是可入肺颗粒物。受雾霾的影响，大部分地区陷入严重空气污染之中，说到这里，再给大家介绍两个经常出现在天气报道中的术语：AQI 和 API。AQI 指的是空气质量指数 (Air Quality Index)，API 指的是空气污染指数 (Air Pollution Index)，API 的指数越大，说明空气污染越严重。另外在英语中我们还可以用 airpocalypse表示雾霾天气，这个词是由 air 和 apocalypse 拼缀而成，指的是由烟雾、灰尘、天气共同作用导致的极端污染的空气，可以翻译成空气末日，末日空气。
严重的雾霾天气使防尘口罩 (anti-dust respirator/mask) 近乎脱销 (sell out)，空气净化器 (air purifier) 产品也卖到了断货。前段时间还传言雾霾天气会影响生殖能力 (reproductive capacity)?!(汗~)是不是真的呢?专家回应，即使有影响也不会太大。目前来看，雾霾对人类健康最直接的危害还是增加呼吸系统疾病 (respiratory system disease) 的发病率。所以面对雾霾天气，我们要尽量减少外出，在家记得关闭窗户哦!建议吃货们 (foodies) 多吃一些清肺化痰的食物，比如：梨 (pear)、橘子 (orange)、黑木耳 (black fungus)、银耳 (snow fungus) 等。
Dear Bill,
Im glad to receive your letter,thank you for your caring for the weather and my health.Now Id like to tell you something about the smog.
Since the winter last year,the smog has occurred a lot of times.it has done great harm to our daily life.many traffic accidents happened just because of the heavy smog weather,more and more people have to go to see the doctor because the serious disease caused by the smog,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 smog.
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.
According to me, I will go to school by bike or on foot, and I wont 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?im looking forward to your reply.
Yours,
Li Hua
The Clear and Blue Sky
With the broadcast of smog,this long-standing environmental problems,become the hot discussion once again.According to some reports,the frequent appearances of smog obscure the clarity of the sky recently.Some people drove slowly on the road because they could not see clearly. They also suffered from many illnesses caused by smog.
Smog is the general expression of various higher-than-permitted suspended particulate matter (such as PM2.5) in the atmosphere,which express the state of air pollution .It contains fog and haze,both of them are disastrous weather. Fog consists of a large number of tiny water or ice crystals.Its actually a harmless natural phenomena that makes visibility worse .Haze is air pollution in which is mixed up with dust, smoke and other dry particles. The components that make up haze may have negative effect on peoples health, especially for children and the old.
So its necessary to find out the reason why leads to smog and work out the resolution.If we trace the cause for smog weather ,the main points are natural causes that include windblown dust and manmade causes which include three aspects.Firstly,china s air quality standards are rather lax and evaluation factors are limited.Secondly,some enterprises just go for economic interests instead of observing relevant law and regulations.Obsolete equipment、industrial fuel burning and manufacturing operations are high likely to emit much wasted air.Thirdly,across our society ,relevant protection awareness has not built up.Just for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for smog.
To settle this problem,a series of meaures should be taken as follows.Primarily,we should establish a sound control system of smog. Not only can environmental protection departments strengthen air monitor,but government should enact more strict laws and regulations.Moreover,Reduce pollution sources is the fundamental solution to cut air pollutants. For example,we can reduce the amount of fuel vehicles or close down high polluting enterprises.Developing green and energy-saving energy can lower the emission of smog.Last but not least, People should do personal protection.They need to reduce the time for outdoor sports and pay attention to rest in smog days.Everyone all over the country should take measures to reduce the smog weather. We can use more public transport such as the bus and the underground so that the number of cars will be limited.Also,people should plant more trees. As far as Im concerned ,if we work together to do such measures ,smog weather will vanish completely and we will get clear and blue sky.
