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 es from good protection. So we should do what we can to make a difference. Try to drive less and choose airfriendly products. Only when everyone has the environmental awareness can we have cleaner air.Hoping to hear from you soon and share your good ideas.Recently，haze weather has bee a daily one right here in large part of are forced to wear the mask to avoid breathing poisonous it is necessary to find out the reason why leads to that and work out the we trace the cause for haze weather ，the main points are as follows ，first，china s air quality standards are rather lax and evaluation factors are limited，so you will see that current air appraisal system has ，some people just go for economic interests instead of turning out products according to relevant law and tend to use obsolete equipment in which they are high likely to emit a great deal of wasted air.Third，across our society ，relevant protection awareness has not built up so that people havent formed a habit of using green product and saving energy as much as 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 the haze weatherTo settle this problem，a series of meaures should be taken as ，we should strengthen air monitor to lower the levels of small particulate ，we should enact more strict laws and regulations and keep perfecting our current law on environmental protection to regulate people s daily action and the industrial production and punish those factories that ignore the protection and keep emitting dangerous material that cause haze. Third，we should develop green and energysaving energy to lower the emission of haze and improve air far as i amconcerned ，if we work together to be able to do such measures ，our environment will getting better and better and haze weather will vanish pletely. 2013年1月14日上午11時(shí)，北京市環(huán)保局（Beijing Environmental Protection Bureau）結(jié)合多個(gè)部門(mén)召開(kāi)新聞發(fā)布會(huì)（press conference），結(jié)合相關(guān)委辦局一起，介紹《北京市空氣重污染應(yīng)急方案（emergency plan）》施行情況，以及近幾天空氣質(zhì)量情況及預(yù)告信息。從1月7日起，中國(guó)中東部大部地區(qū)出現(xiàn)持續(xù)霧霾天氣（smog），大部地區(qū)霧霾日數(shù)在3天以上。北京、天津、石家莊、唐山、邯鄲、保定等城市污染嚴(yán)峻（heavily polluted），部分城市重度污染持續(xù)時(shí)間達(dá)6天。其中，北京于1月13日10時(shí)35分發(fā)布了霾橙色預(yù)警信號(hào)（orange
