the TopicPollution is a major problem in the world today.It damages the environment and is harmful to humans,animals and plants.Although pollution can be a result of natural disasters such as earthquakes and forest fires,it is mostly caused by human activity.With the increase of population and the development of technology,pollution in our modern-day world has reached dangerous levels.Clean and fresh air is now a luxury in many big cities and the water in many of our rivers and lakes are too polluted to drink and swim in.The environment is our life support systemthe only one that we have.We should do our best to save it before its too late.3PollutionisamajorproblemSectionBSectionCSectionALeading inPlus ActivitiesAround the TopicDirections:Land,air and water pollution are

pollution?keykey8Directions:YouwillhearashSectionBSectionCSectionALeading inExploring the TopicAround the TopicSuggested answer:Too many cars have caused a lot of serious problems in our world.Besides congestion,accidents and fast fuel consumption,cars are responsible for a good part of air pollution in big cities.One possible solution is to design and develop clean cars and clean fuels.In Shanghai,some of the public buses begin to run on natural gas,which does not give off as much carbon dioxide as petrol.Return9Suggestedanswer:Return9SectionBSectionCSectionALeading inExploring the TopicAround the TopicSuggested answer:Another solution is to develop modern public transportation systems and restrict the use of private cars.If the price of petrol rises constantly and the public vehicles are efficient and convenient enough,most people will not buy private cars.Thus,the total number of cars in big cities will reduce greatly.On the whole,the elimination of air pollution needs the collective efforts from the government,the public and the environmentalists.Return10Suggestedanswer:Return10SectionBSectionCAroundtheTopicSection ASmoginMyCitySectionA:11SmoginMyCitySectionA:11Text AExercisesSectionBSectionCAroundtheTopicSection ASmog is a type of air pollution that occurs when smoke or other pollutants in the air mixes with fog.The word“smog,”a blend of“smoke”and“fog,”was first coined in the early 20th century to describe the smoky fog that hung over London and some other large cities at that time.Unfortunately though,more than one hundred years later,smog remains a familiar sight in many places around the world,especially in big cities with a lot of industry and traffic.12SmogisatypeofairpollutiText AExercisesSectionBSectionCAroundtheTopicSection AText A portrays a city plagued by smog.The writer describes how serious the smog condition is in the city where he lives and explores the underlying causes of the problem.Although the name of the city is not revealed,it stands as a perfect example of a city that has yet to find a balance between economic growth and environmental protection.13TextAportraysacityplaguedWarming-upExercisesSectionBSectionCAroundtheTopicSection ASmog in My City When I wake up in the morning,I pause briefly before opening my curtains,and what I see

am not checking up on the weather.Instead,I want to know exactly how bad the pollution is going to be.On some mornings,it is truly horrible.It is as if the whole city has been turned into a smokers room with a yellowish color staining the sky.Para.2我并不是想看看天气如何，我只是想知道这一天的空气污染将会有多严重。有些早上，污染确实非常可怕，整个城市仿佛变成了一个吸烟室，天空被染成了淡淡的黄色。15IamnotcheckingupontheweWarming-upExercisesSectionBSectionCAroundtheTopicSection APara.3And this month,pollution in my city went from bad to.well,dangerous.The hospitals were filled with patients,old and young,suffering from breath-related problems.People were warned to stay indoors and the streets were unusually quiet.这个月，整座城市的污染程度由严重变成了危险。医院里到处都是病人，老的少的，患的都是和呼吸道相关的疾病。人们被警告要呆在室内，街道也变得异常安静。16Para.3Andthismonth,pollutiWarming-upExercisesSectionBSectionCAroundtheTopicSection ASales of air purifiers for homes,as well as face masks,rocketed and some stores simply ran out.Even for a city that is used to pollution,this was an emergency.家用空气净化器和口罩的销售量猛增，有些商店干脆脱销。即使对于一个已经习惯了污染的城市，这种情形也是一个紧急状况。Para.417SalesofairpurifiersforhomWarming-upExercisesSectionBSectionCAroundtheTopicSection AFor years,the local authorities often played down the pollution in the city,insisting it was fog in most cases,despite evidence to the contrary that was plain for all to see.Para.5多年来，地方政府对这座城市的污染状况常常轻描淡写，坚持声称大多数的情况只是雾而已，尽管与此相反的证据显而易见。18Foryears,thelocalauthoritiWarming-upExercisesSectionBSectionCAroundtheTopicSection AFaced with public pressure,the local authorities started publishing the hourly air-quality readings this year.And when the recent unusually heavy smog hit,the state media,for the first time on this issue,made its voice heard.面对公众压力，地方政府今年开始每小时发布一次空气质量指数。当最近一次特别严重的雾霾来袭时，官方媒体首次对这一污染问题发出了声音。Para.619Facedwithpublicpressure,thWarming-upExercisesSectionBSectionCAroundtheTopicSection AThe pollution story led the countrys main evening TV news program.Even the major national daily newspaper ran a headline asking“Whats wrong with our air?”.Well,the answer is not far to seek.The problem is caused by the country developing at a speed and scale unheard-of in history.It has been growth at all costs,resulting in widespread environmental worsening.Para.7污染的报道出现在国家主要的晚间电视新闻节目的头条位置，连最大的全国性的日报也刊登了这样的标题：“我们的空气到底怎么了？”答案并不难找，污染问题是由这个国家空前的发展速度和规模造成的。这种不惜一切代价的增长，导致了环境的广泛恶化。20ThepollutionstoryledthecoWarming-upExercisesSectionBSectionCAroundtheTopicSection ACoal-burning energy plants power the countrys factories;they provide the heat for hundreds of millions of homes,but they also emit poisonous gases into the air.In my city alone,several million cars choke the streets,an illustration of the countrys growing prosperity.But all these vehicles,normally bumper to bumper,are also a sign of a country that is not coming to terms with pollution.Para.8燃煤发电厂为这个国家的工厂提供电力，也为数亿家庭提供暖气，但是它们也把有毒有害气体排放到空气中。单单就我们这座城市，几百万辆的车把街道挤得水泄不通，这是国家日益繁荣的例证，但是，车辆一辆紧接着一辆的状况也表明了这个国家还没有真正地来面对和处理污染。21Coal-burningenergyplantspowWarming-upExercisesSectionBSectionCAroundtheTopicSection AAnd it is not just the air quality.Lakes,rivers and underground water supplies have all been badly polluted by lightly regulated industry.Almost no one in the city trusts the water that comes out of their taps.这不仅仅只是空气质量，由于工业监管不力，湖泊、河流和地下水供应都受到了严重的污染。在这座城市，几乎没有人相信他们水龙头里流出来的水是安全无害的。Para.822AnditisnotjusttheairquaWarming-upExercisesSectionBSectionCAroundtheTopicSection ASo maybe the great smog of this city in recent days will mark a turning point.A time when the people say:“We need to put quality of life before economic growth.”In recent months,there have been several large-scale protests against factories being built in various cities.Para.9也许这个城市这几天的严重雾霾将成为一个转折点。在这个时刻，人们要说：“我们需要把生活质量放在经济增长之上。”在最近几个月，已经有几次大规模的抗议活动，反对一些城市正在兴建的工厂。23SomaybethegreatsmogofthiWarming-upExercisesSectionBSectionCAroundtheTopicSection APara.10But a huge sea change looks unlikelyfor now,anyway.Economic growth remains the citys top priority.Without it,large numbers of people could be left unemployed.There are still millions of people who want the keys to their first car,their first air-conditioner,even a fridge.但是彻底的改变看起来不太可能，至少目前不可能。经济增长仍然是这座城市的重中之重，没有它，大量的人员会失业。还有数以百万计的人想拿到他们第一辆车的钥匙，他们的第一台空调，甚至一台冰箱。24Para.10ButahugeseachangeWarming-upExercisesSectionBSectionCAroundtheTopicSection A谁又能剥夺他们实现梦想的权利？出于这个原因，在这个城市，洁净的空气在未来的几年里仍可能非常稀罕。一些富人把他们的孩子带到加拿大或澳洲定居，但对于大多数人，他们没有这样的选择。Who is going to be the one to deny them their dream?For that reason,clean air is likely to remain a rarity in my city for years to come.Some wealthy people are taking their kids to live in Canada or Australia.But for most,that is not an
