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 referre d 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, which also 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.Section ⅠWelcome 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 —must we choose？’With me are Ms Lin Shuiqing⑥，from the Green Society, and Mr Qian Liwei，a business development consultant.We are following our usual schedule⑦for debates.Ms Lin Shuiqing will speak first for three minutes.Mr Qian Liwei will follow, also for three minutes.Then we will open the floor⑧for discussion.If you have any questions or comments, you can use this time to express⑨them. 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。

我今天首先要谈的是化学废物如何破坏世界上的大片区域的。
许多地方已经被毁，许多动植物已经死亡。
这很可怕。
工厂生产大量有害化学物质。
它们产生的废物进入大气，使我们生病。
其他种类的废物流入水中，杀死河流及海洋生物。
捕鱼船也在毁灭大量的海洋生物。
这些船捕捞大量的鱼，而不给它们时间产卵。
这将导致今后我们食用的鱼的数目更小。
一方面我们在毁灭环境，另一方面我们继续生育越来越多的人口，这些人口需要更多的土地居住，也需要更多的食物食用！与1800年相比，世界人口的数量已经增长了六倍。
现在约有七十亿人！It is our duty○29to try to cut back on○30○29duty['djuːtI]n．责任，义务，本分production○31and reduce the number of○32 things we make and buy○33.The amount of rubbish we produce○34is turning into○35 a big problem；we need to think more about recycling○36our waste.It would be good to increase the amount of waste we recycle○37，and teach people ways of living that do not harm the environment○38.We may even create more jobs and help our country become more developed at the same time.Thank you.
