T:Are you ready?Who can give us a talk about the first topic?S A,how are people's eating habbits changing over the years?S A: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,people's 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,S B?S B:It is all because of the Party's 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?S C: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,S D?S D:Yes,I do.And I want to give an answer to the three question.T:Good,please say that.S D:With the changes in people's 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 Ⅳ.ListeningT:So much for the discussion.Next we'll do listening.The passage you'll 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 you'll have to do after listening to the passage?(Ss:Yes.)During listening,I'll 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 Ⅴ.SpeakingT:Now let's 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 theland.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:S E:My advice would be….I advise you to do….S F:I think you ought to….You.d better….S G:If I were you,I would….I would advise you.S H:I don't think you ought to….Making a decision:S I:In my opinion,we should…I think/believe you should…S J:I don't think it is necessary to do sth.….We must decide….S K:I hope we can make a decision.(Teacher writes all the expressions above on the Bb.)T:Now let's have a discussion,using the expressions on the blackboard later,I'll ask some students to act it out.Sample diaolgue:S a—villager A;S b—villager B;S c—villager C;S d—villager DS e—the village leaderS e:As we all know,we are given a large piece of land.I've got all of us here to have a discussion and decide how to use the land.Please give us your advice.S a:I advise we should grow corn on this piece of land.It's 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.S b: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.S c: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.S d:I think we'd 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.S a:That's a good idea.But it will need a lot of money to do this.I hope we can make a decision today.S e:We must make a decision.My opinion is that we do as S D said.Any other opinions?S b and S c:I agree with you.Step Ⅵ.Summary and HomeworkT:In this class,we've 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 blackboard.That's all for today.Class is over.____________________________________________________________________________________________________________________________________________________The Second PeriodTeaching Aims:1.Enable the students to learn something about modern agriculture from the text.2.Enable the student to master the new words and expressions in the text.3.Get the students to have the ability to grasp the general idea of an passage as fast as possible.Teaching Important Points:1.How to improve the students' reading ability.2.How to get the students to master the new words and expressions of the text.Teaching Difficult Point:How to improve the students' reading and writing ability.Teaching Methods:1.Discussion to raise the students' interest in agriculture.2.Ask-and-answer method to help the students

Ⅰ.Greetings and RevisionGreet the whole class as usualT:At the end of the last period,I asked every one of us to join in a discussion.Now I'll ask a group to repeat the discussion.Who will act it out for us?Wang Hong,act it for us with your group,will you?Wang:Yes.…(Teacher asks two groups to repeat their discussion before the class.)step Ⅱ.Preparation for ReadingT:So much for revision.Please turn to Page 113.Let's learn the new words and expressions together.Li Ming,read the new words and expressions of this period,please.Begin with the word “arable”and end with the word “soil”.(Teacher and the students learn the new words and expressions together.Teacher corrects students' mistakes in pronunciation and gives simple explanations of some words if necessary.) T:Are there any students coming from the countryside in our class?Ss:Yes.A lot of us students are from peasant family.T:Have you ever worked in the fields,Wang Fei?Wang:Yes.I often work in the field with my parents.I can do a lot of farm work.T:Have you ever heard of anything about farming in the past?Ss:Yes,I have.T:Now turn to Page 34.Let's do pre-reading.Discuss the questions.Group work.Write your answers on a piece of paper.(After a few minutes.)T:Are you ready?(Ss:Yes.)Who would tell us something about traditional and modern farming?S A: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?S B:I'll 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.S c:I'll 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 becoming richer and richer day by day.T:Very good.Step Ⅲ.Fast ReadingT:Are you ready?Ss:Yes.T:Please give us the answers to the questions.S D:In the 1980s,more advanced technical information was brought in from abroad.S E:Both food production and taking care of the environment are important.And future agriculture should depend on high technology as well as traditional methods.S F:I think taking care of the environment is more important.Because we have only one earth.S a:In the last two lines,“which”refers to“golden rice”.T:What is the other name of “golden rice”in the text?S a:GM rice.Step Ⅳ.ReadingT:Now read the text again and answer the questions in Post Reading.If you are not sure about your answers,have a discussion with your classmates.(After the students' discussion)T:Please turn to Page 35.Let's answer the questions.S H,give your answers to the first fivequestions.S H:They are:1.D 2.A 3.C 4.C 5.CT:Is he right?Ss:Yes,he is right.T:Now let's do Part 2.S I:I want to change apples.I want them not only to grow bigger and more delicious,but also of the same size.Because some of the apples now are smaller and not delicious and the apples of the same size are popular in the market.S J:I 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 become richer.T:That's a good idea!I have the same opinion as you.S K:I want to change carrots.I want them to grow much bigger.Because the carrots our villagers grow are smaller.S L:I want to change the vegetables people usually eat.I want them to be better for people's health.So they will spend less money on medicine.S M:I want to change cows.I want them to have more babies.So they will not be expensive to buy.If so,more farmers can buy them and become rich.S N:I want to change fruit trees.I want to plant the trees growing in the south.So we will have more kinds of fruits than ever before.T:You've done well.After class,continue to think about more good ideas.Now I'll explainyou still have something you find difficult to understand.(Teacher goes among the students to explain any questions raised by the students.)Step Ⅴ.Listening and Reading AloudT:Let's listen to the tape.I'll play it twice.The first time I play it,just listen.When I play for the second time,you

for the food produce farmers? that the land arable on this is It :a ⎪⎪⎩⎪⎪⎨⎧t.environmen the harming? without productional agricultur increase? to s technique new develop to started scientists 1990s,early the From :b t.environmen the harming without?production al agricultur increase ¡ to s technique new develop to started scientists that 1990s early the from is It :a T:Are sentence a and b in each group have the same meaning? Ss:Yes.Both of the two sentences in each group have the same meaning. T:Are there any difference?S a ,can you tell me?S a:Yes.Sentence a is the emphatic form,while sentence b is normal.Am I right?T:Yes,you are right.“It is/was…that…”is the emphatic construction.This structure can be used to emphasize almost any part of the sentence (except emphasizing the verb).Besides,if we emphasize the subject,“who”(referring to a person)is possible instead of “that”.If an object is emphasized,“whom”(referring to a person)is possible.Look at the screen.Read this sentences and rewrite them,emphasizing the parts underlined,using“It is/was…that…”.Please prepare them inT:Are you ready?(Ss:Yes.)Please change these sentences.One student,one sentence.Who will be the first?S b:I'll try.Sentence 2:It is the children who/that often help the father and mother do the farm work.S c:I want to rewrite the second sentence,but I'm not sure whether I should use“is”or“was”.T:Here you should use “was”.S c:Sentence I:It was in 1993 when a tomato was developed that was very different from any grown before.T:Is he right,S d?S d:Yes.T:You're both wrong.We should pay special attention to “that”when we emphasize the adverbial of time and place.In both situations,we should use“that”instead of “when ”or “where”.Are you clear about that?Ss:Yes.T:Let's go on with the other sentences.S e:Sentence 3:It is the shortage of arable land that the biggest problem of Chinese farmers is.S F:Sentence 4:It is the plants grown in green houses that are protected from the wind,rain and insects.S G:Sentence 5:It is high technology as well as traditional methods that future agriculture should depend on.T:Are they right?Ss:Yes,they are all right.Step Ⅳ.PracticeT:Now let's do the second part of Grammar.Rewrite the sentences,emphasizing as many parts as possible.First look at Example.Read it carefully and then do the exercise.You can have a discussion with your classmates if you have any questions.A few minutes later,we'll check the answers.(When students finish,teacher shows the answers on the screen and get the students to checkT:In this class,we've done some exercises about Word Formation.Please remember these words on the blackboard(Pointing to the blackboard).We should also remember the emphatic construction:It is …that(who,whom)…What should we pay special attention to?Who can tell us?S h:1.The verb can not be emphasized.2.When we emphasize the adverbial,we should remember that we cant't use when or where.T:(Write what the student said on the blackboard.)That's right.After class,we should do more exercises so that we can master it.Today's homework:Do the

ready?(Ss:Yes.)Who will give us the first answer?S D:It includes the following advice:growing green vegetables and fruit trees,keeping cows,sheep and fish in lakes.There are also instructions for making wine.T:Please go on with the questions.V o-lunteers!S E:2.Firstly as a farmer,you should remember to do things at the right time of the year,Ifso,your work will be less and the result will be better.S F:3.Before you sow or plant crops,you must clean rough ground and remove weeds.S G:4.Because he wanted the animals to destroy the weeds or eat them.T:Do the farmers get rid of weeds in this way now?S G:No,they pull up the weeds or destroy them with a hoe.T:Yes,they hoe up the weeds or use weed killer.Please go on.S H:5.If you want to reach the best harvest,you should change the crops in your fields.T:What does that mean?S H:For example,if you plant rice in a field one year and wheat in the field the next year,you will harvest good crops.That is to say,do not plant the same crop year after year in the same field.S I:6.Wheat should be planted close together instead of with space.Because Jia Sixie did experiments and showen that.T:Your answers are right.That is because you have a

Unit 19Modern agricultureⅠ.Teaching Goals:about modern agriculture and the effects it has on people's life.giving advice and making decisions.“It” for emphasis.statistical graphs.a plan for a vegetable garden.Ⅱ.Teaching Time:Five periodsⅢ.Background Information:American Small FarmLast year,at harvest time,we visited the Steenhoek farm,which is 2 200 mu,or 340 family farms are run entirely by family members,with every member playing a vital part in the of these families are descendants of Dutch immigrants who settled here over a century ago.The Steenhoek farm supports 3 family of includes three children and 2 we will see,this family is an excellent example of hardworking,experienced farmers who stay on the land not purely because of profit,but because they are living a life-style that satisfies percent of the Steenhoek's acres are devoted to pasture land,on which they raise 120 beef rest of the land is used for growing corn.Fifteen years ago,the American farm economy was could specialize,raising one crop,or one type of ,with an uncertain farm economy,such an idea is considered foolhardy,and diversifying is one way that farmers can lesson their risk of example,if weather affects the size of a crop,the sale of the livestock will make up the the animals are plagued by disease,at least there is grain to take to market.Kendall Steenhoek,Simon's eldest son,divides his time between running this machine shop and farming zoo acres of attended a community college in Iowa for two years to study diesel he opened this repair shop for farm also plants and harvests over 30 000 bushels of corn each year,but it is the income from the repair shop that has enabled him to stay within the farming heavy equipment used on the farms today is in constant need of maintenance,and requires precision tooling for far,the most impressive and certainly the most costly piece of farm equipment used on a small farm is a harvesting machine called a combine,which can cost up to $100 000.This type of machinery is what makes the American farm so a combine,one man and his family can harvest an entire crop of a 500 acre farm in two value of the combine is that it performs several it moves through a field of corn,this sophisticated machine cuts the stalk,plucks the ear,discards the stalk,shucks the corn kernels off the ear and deposites the kernels in a storage bin in the ,a spinning device in the rear of the combine shreds the husks and shafts and scatters them across the field,to serve as mulch,cutting down on the possibility of soilerosion from winter machine is even more amazing when you think that it has been in use on American farms for only one generation.Every living cell contains are too small to be seen in a microscope,but they are vitally set of genes in the body contains all the instructions needed to make a human genes determine hair determine the shape of a genes help determine your height and even your weight.Genes are made of a chemical called DNA—the letters stand for deoxyribonucleicacid(脱氧核糖核酸).In the early 1950's,two scientists,Francis Crick and James Watson,figured out how the parts of DNA fit scientists understood this structure,it became possible to take pieces of DNA apart and put them together in new kinds of genes could be made in this manner.Scientists have studied the genes of many plants and have worked out which genes affect the color of a tomato and the stickness of its out which genes determine which features is called genetic mapping,scientists have begun the Human Genome Project,an ambitious effort to map all the genes in the human body.Some genes may be example,something might be wrong with the gene that makes blood clot(凝聚).An individual born with this defective gene could suffer serious hemorrhages(出血)or even bleed to death because his or her blood fails to scientists ever learn how to map all the genes in our bodies,they could determine whether or not an unborn child has any defective might even discover how to treat these genes before the child is born.The First PeriodTeaching Aims:the students' speaking ability by practising giving advice and making decisions.the
