discussion with the students about the mistake Wang Ping made.Let the students have a clear understanding and correct it.)step .Preparation for listening and speakingT:Today,were going to learn a new unit,Unit 19,Modern Agriculture(Teacher writes the following on the blackboard:Unit 19 Modern agriculture,the First Period).First,lets learn the new words of this period.Look at the screen:New words:produce n.产量、产物、农产品effect n.结果、影响、作用dike n.堤坝；排水沟drought n.干旱leader n.领导者lead v.领导、带领cane n.细长的茎、藤条sugar-cane n.甘蔗tobacco n.(烟草)制品；抽烟local adj.地方的、当地的(Teacher asks one student to read the new words,then corrects the mistakes the student made.)Step .Warming upT:Please turn to Page 32.Lets do Warming up.(Teacher shows the graphs on Page 32 on the screen.)Look at the two graphs and discuss the questions on Page 32.You can do it in pairs or groups.In a few minutes,Ill ask some students to talk about them.(Students begin to discuss the questions.And teacher goes and joins them.A few minutes later,teacher says the following.)T:Are you ready?Who can give us a talk about the first topic?SA,how are peoples eating habbits changing over the years?SA:From the first graph,we can see that the eating habits of the people in our country have changed greatly.Before 1949,they had not enough to eat and often went hungry.Once natural disasters happened,a great number of people would die of hunger.Before the reforming and opening to the world,grain was still a big problem.People mainly lived on corn and few kinds of vegetables.Since the 1980s,especially the 1990s,peoples eating habits have greatly improved.People can eat whatever they want.More and more people eat less grain,more meat and eggs and so on.More and more people turn their eyes to meat,eggs,milk and all kinds of green vegetables.T:Why do you think this happens,SB?SB:It is all because of the Partys good policies.T:Very good.It is true and everyone can see that.How has agricultural produce changed during the first half of the 1990s?And what do you think caused these changes?SC:From the first half of the 1990s,scientists started to develop new techniques to increase agricultural production without causing damage to the environment.Especially the new technique, “GM”,has made agricultural production increase continuously.Scientists develop new kinds of seeds,better cows,pigs,sheep as well as fish.It is the new techniques that make all this possible.T:Do you agree with him,SD?SD:Yes,I do.And I want to give an answer to the three question.T:Good,please say that.SD:With the changes in peoples eating habits,agriculture as well as nature will have to change,too.People are eating more meat and milk.That is to say,they need more fish,pigs,sheep and cattle as well as poultry.To feed these animals,we need more grain,especially more grass.To protect our environment,the ways to raise animals have changed.With the development of modern science and techniques,some of the fields are not needed to produce more food.We can grow grass,flowers etc.on them.Less farmers are needed and they can do other kinds of work.Step .ListeningT:So much for the discussion.Next well do listening.The passage youll listen to is about farming.It tells us about farming of all countries in early times and protection of nature and environment.Listen to the tape carefully and do the exercises concerned.Now,read the requirements,please.(Students read the requirements.)Now do you know what youll have to do after listening to the passage?(Ss:Yes.)During listening,Ill play the tape three times.After listening for the first time,you can leave over the ones you are not sure about.You can do them when I play the tape for the second or the third time.Check your answers with your partner after listening.Are you clear?(Ss:Yes.)(At last,teacher shows the answers on the screen.)Step .SpeakingT:Now lets do speaking.This part says that a group of farmers in your area have been given a large piece of land.The villagers together with the village leader have to decide how to use the land.Work in groups of five students.Each group member will play one of the roles.Prepare role cards,discuss the problem and try to make a decision.Before discussion,who can give us some useful expressions about giving advice and making decisions?Giving advice:SE:My advice would be.I advise you to do.SF:I think you ought to.You.d better.SG:If I were you,I would.I would advise you.SH:I dont think you ought to.Making a decision:SI:In my opinion,we shouldI think/believe you shouldSJ:I dont think it is necessary to do sth.We must decide.SK:I hope we can make a decision.(Teacher writes all the expressions above on the Bb.)T:Now lets have a discussion,using the expressions on the blackboard later,Ill ask some students to act it out.Sample diaolgue:Savillager A;Sbvillager B;Scvillager C;Sdvillager DSethe village leaderSe:As we all know,we are given a large piece of land.Ive got all of us here to have a discussion and decide how to use the land.Please give us your advice.Sa:I advise we should grow corn on this piece of land.Its large and flat and machines can go up and down it,so we can spend less time and get more corn.A lot of money can be made after selling the corn.Sb:I think we ought to build a farm there and raise pigs or cows with the grain we harvest.So we can make more money.Sc:My advice is that we should turn it into a garden,and grow flowers there.Then we can sell the flowers.There is nobody here selling flowers.So I think our business will surely be good.Besides,sometimes selling grain or meat is hard,for the price could be too low.Sd:I think wed better design it like this:We build a building of a few floors.In each floor,we can raise one kind of animals.With their wastes,we can raise fish or grow vegetables on the top or in the space which faces the sun.We can also grow mushrooms in the dark places.We can use one quarter of it to do this and build a garden on one quarter so that people can enjoy themselves here.Half of the rest grow flowers to sell and for the other half we can grow grass on it so that our environment will be better.Sa:Thats a good idea.But it will need a lot of money to do this.I hope we can make a decision today.Se:We must make a decision.My opinion is that we do as SD said.Any other opinions?Sb and Sc:I agree with you.Step .Summary and HomeworkT:In this class,weve talked about two statistical graphs and listened to a passage.We have also talked about how to use a large piece of land,using some expressions of giving advice and making deicisions.These expressions are:“”(Pointing to the blackboard.)After class,choose a subject as you like with your pratner and have a discussion,using the expressions on the

modern farming?SA:In the past,farmers grow crops in the traditional way:Use cattle to plough the field;farmers work in the field most of the day all year round,but they could not produce enough food for the whole population.Now they grow crops in the modern way.They use modern techniques in their fields,such as chemical fertilizers,greenhouses and so on.T:Who would answer the second question?SB:Ill try.The advantages are:chemical fertilizers,electronic pumps and other advanced technology are used.Farmers can spend less time on farms and much more grain is produced.The disadvantages are:the air,the water and the soil round us are more or less polluted.Sc:Ill say something about other changes that have taken place on farms in the last 100 years.In the past,we depended on heaven and we could do little when natural disasters happened.Now,we can do artificial rainfall.GM makes better seeds possible.In the same fields,better seeds can give us much more grain.Besides,all kinds of scientific ways of farming are used in farming.Farmers in our country are being richer and richer day by day.T:Very good.Step .Fast ReadingT:Now read the text fast and then

from abroad.SE:Both food production and taking care of the environment are important.And future agriculture should depend on high technology as well as traditional methods.SF:I think taking care of the environment is more important.Because we have only one earth.Sa:In the last two lines,“which”refers to“golden rice”.T:What is the other name of “golden rice” in the text?Sa:GM rice.Step

want to change fruit trees.I want them to grow shorter so that the fruits on them are easy to pick up.And they must give us more fruits so that the farmers can make more money and bee richer.T:Thats a good idea!I have the same opinion as you.SK:I want to change carrots.I want them to grow much bigger.Because the carrots our villagers grow are smaller.SL:I want to change the vegetables people
