我早晨起来，在打开窗帘前稍作停顿，看到窗口我很可能会将一天基调定为休息。下一页上一页Iamnotcheckingupontheweather.Instead,Iwanttoknowexactlyhowbadthepollutionisgoingtobe.Onsomemornings,itistrulyhorrible.Itisasifthewholecityhasbeenturnedintoasmokers’roomwithayellowishcolorstaining

thesky.我没有查询过天气。相反，我想知道到底将会有多糟糕污染。在一些早晨，这真是太可怕了。整个城市天空被染成黄色，好像已经变成了一个吸烟者房间。上一页下一页Andthismonth,pollutioninmycitywentfrombadto...well,dangerous.Thehospitalswerefilledwithpatients,oldandyoung,sufferingfrombreath-relatedproblems.Peoplewerewarnedtostayindoorsandthestreetswereunusuallyquiet.本月，在本市污染坏到…好吧，糟糕。医院人满为患，年老和年轻患有呼吸相关疾病问题。人们被勒令呆在室内，街道异常平静。上一页下一页Salesofairpurifiersforhomes,aswellasfacemasks,rocketedandsomestoressimplyranout.Evenforacitythatisusedtopollution,thiswasanemergency.家用空气净化器，口罩销量飞速上升，商店卖完了仅剩货物。这是一个紧急情况，即使是一个用于污染城市。上一页下一页Foryears,thelocalauthoritiesoftenplayeddownthepollutioninthecity,insistingitwasfoginmostcases,despiteevidencetothecontrarythatwasplainforalltosee.多年来，地方政府往往对城市污染轻描淡写，在大多数情况下坚称这是雾，尽管有证据能够清楚得表明相反情况。上一页下一页Facedwithpublicpressure,thelocalauthoritiesstartedpublishingthehourlyair-qualityreadingsthisyear.Andwhentherecentunusuallyheavysmoghit,thestatemedia,forthefirsttimeonthisissue,madeitsvoiceheard.面对公众压力，地方政府今年开始公布每小时空气质量汇报。近期，异常沉重烟雾袭来，国家媒体首次在这个问题上，发出了自己声音。上一页下一页

environmentalworsening.污染事件主导了该国主要晚间电视新闻节目标内容。国家主要新闻日报提了一个标题问：“我们空气有什么问题？”答案是在不远处寻找。该问题是由该国发展速度和规模在历史上是空前而造成。它一直增加，不惜一切代价，造成广泛环境恶化。上一页下一页

industry.Almostnooneinthecitytruststhewaterthatcomesoutoftheirtaps.燃煤发电厂为全国工厂供电;它们为亿万家庭提供热量，但它们也在空气中散发有毒气体。仅仅是在我城市，几百万汽车使街道堵塞，这说明国家日益繁荣。不过，这些车通常一辆接一辆，这也是一个国家是否有污染标志。不只是空气质量。湖泊，河流和地下水供给都受到那些监管宽松行业严重污染。在城市里几乎没有些人信任自来水。上一页下一页

Somaybethegreatsmogofthiscityinrecentdayswillmarkaturningpoint.Atimewhenthepeoplesay:‘‘Weneedtoputqualityoflifebeforeeconomicgrowth.”Inrecentmonths,therehavebeenseverallarge-scaleprotests

againstfactoriesbeinginvariouscities.所以，可能这个城市最近几天大雾霾将标志着一个转折点.一时间人们在说“我们需要把生活质量放在经济增加前面”近几个月来，在各个城市有过几次针对工厂大规模抗议活动。上一页下一页

但改变大海看起来不太可能——就当前而言。经济增加依然是城市重中之重。假如没有它，大量人可能会失业。仍有数以百万计人想要他们第一辆车，第一台空调，甚至是一台冰箱全部权。什么会否定他们梦想？答案是多年来在我城市洁净空气依然是罕见。一些有钱人正带着他们孩子住在加拿大或澳洲。但对于大多数人来说，这不是一个选择。上一页下一页

Asforme,afteraboutfiveyearsoflivinghere,Ihaveorderedmyfirstairpurifier.AndInowwearafacemaskforormybikeridetowork.Andeverymorning,beforeopeningmycurtains,Ipauseandhopethatthewindhasblownthepollutionaway.至于我，在这里住了五年，我买了我第一个空气净化器。我现在戴口罩、骑自行车去上班。天天清晨，在打开我窗帘之前，我停下来，希望风吹走了污染。上一页下一页tonen.[语]声调，语气;
