SThe Cause and the Effect of the HazeWith the deterioration (恶化) of air quality, the phenomenon of haze (雾霾) appears more and more. Recently the haze in many regions is merged into mist as a severe weather warning forecast together, which was referred as “haze weather”. There are several causes for the haze.The main cause is that the atmospheric pressure is low and the air circulation is not smooth. As a result, the tiny particles (颗粒) in the air are gathered, floating in the air. Second, the dust is too much on the ground and the humidity (湿度) of the air is low, so it is easy for the dust to be stirred up. Automobile exhaust (汽车尾气) is the main pollutant (污染物). In recent years, a great number of city cars appear in the street. Accordingly, the more cars make the more pollution, whichalso caused the haze. Additionally, the factories also produce the pollution. The haze often appears in winter, because winter heating lets out the pollutants into the air.Out of question, the haze has bad effects on people's health. It is reported that some people have coughs or headaches because of the haze. The doctors say, “the haze will harm people's respiratory system (呼吸系统), even lead to death.”On the environment, the haze causes the decrease of the atmospheric visibility (能见度), which has blocked traffic. In a word, the haze makes the people's life inconvenient.SectionⅠWelcome to the unit & Reading — Pre-readingThe economy①or the environment — must we choose?TV host②： James LongSpeakers: Lin Shuiqing, a spokeswoman③fromthe Green SocietyQian Liwei, a business development consultant④James Long：Good morning.Today's debate⑤question is，‘The economy or the environment ①economy[I'kɒnəmI]n．经济(情况)；经济体②TV host电视节目主持人③spokeswoman['spəʊkswʊmən]n．女发言人spokesman n．发言人④consultant[kən'sʌltənt]n．顾问⑤debate[dI'beIt]n．&v i.辩论；争论，讨论⑥表语with me提前，构成完全倒装句。
