Have a short discussion in pairsplease(Ss have a short discussion and then the teacher asks one or two pairs to say their answers)Well doneNow1ets listen to the second partListen carefully to outline the speakers two arguments. Fill in the table in Part 2Are you ready?Ss：YesT：OKLets begin(Play the tape twice for Ss to Listen and write down their answersPause the tape if necessary. Then ask several students to read out their answers)T：Now，lets listen to the tape again to check your answers(Play the tape once more and then check the answers with the whole class)GoodP1ease think a bout what the speaker will say nextYou call use what you have heard on the tape to predict what will come nextMake an outline like the one in the table and then write down what you think the speaker will sayYou can work in pairs or groups of four as you like (A moment 1ater，ask some students to read out their paragraphs and compare different speeches to choose the best one)Step SpeakingT：Well done! Weve talked much about pollutionWe know that pollution is a big problem facing the earthBut why cant we stop the pollution? Why doesnt our government shut down the factories that pollute the environment badly? Who knows?S：I think our government must have its own opinionMaybe they think the factories are more important than the environmentBecause the government can get lots of money from factoriesIf they shut the factories down ,it will not be able to get so much moneyAnd this is not good for the development of the city or town.T：YesDifferent people have different opinionsThey may not agree with one anotherSo sometimes its very hard to make a decision and to make a changeFor example，we know that coal is a valuable resource that can be used to produce energy，but it also causes serious pollutionWhat should we do with it? (Ss may have various answers) You see，you dont agree with each otherNow，we need to have a meeting to discuss this problemPlease work in groups of fiveYou should play different roles：a businessmana scientist. a local citizen，an environmentalist and a local leaderDifferent people have different opinions(Every person has hisher own opinion) Please discuss the issue first andthen the local leader should summarise and make a decisionYou can have a look at the table and the useful expressions in Speaking Part before you begin your discussionTheyre very helpful(Give the students enough time to have a discussion and then ask the students who play the role of the local leader to read out their decisionsCompare them and choose the best decision)Sample dialogue：A：Today we are here to decide whether we should burn the coalPlease tell uswhatever you thinkB：I think we should burn the coal1f we dont burn it now，maybe it will beuseless in the future，New energy wi1l be used instead of coal，such assolar energyC：But burning coal causes too much pollution to our environment1t pollutes the air badly. If nothing is done to stop its pollution to our earth，then we willHave no fresh air to breatheD：Yes，I quite agreeI think we shouldnt burn the coal now. It would be betterif we spend more money on science to find a better way of using the coalOncewe know how to burn it with out polluting the environment ,we can make full use of itE：That sounds quite reasonable，but its clear that if we want to develop our area as soon as possible，we need moneyHow can we get money? We can only burn the coal to make the factories work to make moneyIf we stop using the coal now ,how shall we continue our production and development?A：OKAll that you said are reasonableI believe that we must try our best tofind a better way to use the coalMeanwhile ,we must make sure that the factories which burn the coal take measures to stop polluting the environmentStep V Summary and HomeworkT：Well doneAfter class，please write down your dialogue in your exercise bookTodayweve talked about our environmentWe know that there are some big problems facing our earthWe must try to do what we can to protect the earthBesides，weve practiced supporting an opinionWho can come to the blackboard and write down the useful expressions weve practiced just now?(A student writes them down on the blackboardIf this student cant write all of them，the teacher may ask another student to write the other expressions)T: Very goodAfter class, you need practise more to master them better.

At the end of the competition the one who think of more problems will win the competition and will be given some small gifts. (After the competition) T: You have done a good job! And I will show you more about the serious problems. (Show them pictures about air pollution, deforestation, water pollution, poor sanitation, wars, starvation, poverty, lack of education)Step three: new words (4minutes) (While explaining, show them the related pictures that will leave a deeper impression on the students) T: There are so many problems. What should we do? The head leaders are worried about this too. So they sat together to talk about the solutions. We call the conferences they attend summits. Meanwhile we call the top part of a mountain a summit. The head leaders from all over the world at the summit are representatives. They are talking about the problems, and most of the problems are in rural areas. Most rural arrears are in poverty. If they still remain in poverty, there will be more violence. So our premiers are worried about this. They hope our country prospers and they also hope we can live in harmony with nature. T: These are all the new words we will meet in the reading passage. Together read after me.

Can you tell me the difference between inverted sentences and usual sentences? Wu Li, would you like to have a try?Sl: Yes. In an inverted sentence, part of the predicate or the whole predicate comes before the subject. In a usual sentence, the predicate comes after the subject.T: Quite right. Sit down, please.
