As a result their eating habits have charged a lot. Today we are going to know some details about it by watchin

7、g the graphs.（三）过程Step 2 Warming upGo through the questions by discussing in small groups with the help of the graphs. Learn with language point at the same time. Present the results form each groups. Sample answers for question 1:1 People are earning more money, so they want to buy and eat more mea

8、t.2 People learn more about healthy food, so they want to eat more fruit.3 Fruit-based alcohol such as wine is better for your health than spirits, so people want to drink more wine and less spirits.4 Fruit juices are healthier than soft drinks such as cola or sprite, so people want to drink more ju

9、ices.5 Eating fish doesnt make people as fat as eating meat, so people like eating more fish.6 When people have more money, they start buying more candy and soft drinks such as cola and sprite; there is a lot of sugar in these products.7 When people eat more fish and meat, they need more oil to fry

10、fish and meat, so more oil need to be made.8 As the population of China grows, more grain (rice and wheat) will be needed, even though each person eats less of it. Some of the grain produce is also used to feed pigs, sheep and cattle.Sample answers for question 2:Agricultural produce has changed ove

11、r the past 20 years. China now produces almost 80% more fish and fruit than twenty years ago. The produce of meat over the same period is up about 60%. Oil and sugar are up about 30% each. Grain and cotton are up 10 and 15% respectively. For further sample answers see introduction to this exercise.

12、These changes happen for different reasons.1 People want to buy different products, so farmers need to grow different things. (Changes in demand)2 Farmers want to make more money. When they can grow extra crops or other crops on their land or land which they cant use to grow grain, they will for exa

13、mple plant fruit trees. In the end, they will bring more fruit to the market. (Changes in supply)3 Some crops bring in more money than other crops, so some farmers change their produce from growing grain to for example fish farming or growing fruit. In the end, they will bring more fish or fruit to

14、the market. (Changes in supply)4 If farmers produce more meat (pigs or chickens) they , need more animal feed. Besides grass, they will also feed them grain products. So they need to buy more grain, which other farmers need to grow more. (Changes in demand)Sample answers for question 3:Changes in ea

15、ting habits and diets will cause changes to agriculture and may also have both good and bad effects for nature.1 First, Chinese people are eating more meat. Next, farmers have to raise more pigs, sheep and cattle. So, more grass is needed to feed more sheep and cattle. So, farmers need more grasslan

16、d. Possibly, they will cut down trees to take more land on which to grow grass.2 If farmers need to raise more pigs, they need to feed the pigs more food. Next, farmers need to buy more grain to feed the pigs. So, other farmers need to grow more grain. They need more land to grow more grain or they

17、must grow more grain on their land. They would destroy nature if farmers want to use more land. They may need to use methods that are harmful to the environment.3 If farmers want to grow different crops they would plant them together. This can be very good for the soil.4 First people start eating mo

18、re fish. Then, farmers have to start fish farms and produce more fish. So, farmers have to choose land they can use to turn into fishponds. If farmers use land for fishponds that could not be used for farming, they create more farmland. If in this way farmers can make more and better use of the land

19、, this will help to develop the economy.5 When people want to eat more fruit, farmers will have to produce more fruit. Many farmers plant fruit trees beside their fields or in places where they cannot grow other crops. In this way farmers make better use of the land, and this will help to develop th

20、e economy.6 First farmers want to grow more different products, because in this way they can make more money. Next, they will plant fruit trees around their fields or around their fishponds. Also, they will plant trees or crops in places where nothing grew before. Sometimes, they will also change ba

21、rren land into fishponds. In the end, there will be more variation. The flowers on the fruit trees will attract bees and other insects. Next, the trees will protect the crops from strong winds and hot sunshine. As a result, the environment will benefit from farms with more variation in crops and lan

22、d use.Step 3 Listening comprehension Now lets have some listening training. LISTENING TEXTFarming and nature are like two flowers on the same tree. When farming goes against nature, all kinds of environmental problems are the result. In ancient times, when people began using the land, farming was no

23、t as it is today. Early farmers moved around the country. They burnt a part of a forest and used this land for one or two years. When they could no longer grow crops on the land they moved on and repeated this somewhere else. Agriculture in this way destroys nature and results in floods and droughts

24、. Some people in South America still practise this kind of farming.Over the past twenty to twenty-five years, farmers have recognised some old truths, already known to ancient Chinese farmers. Farming should not go against nature. If the soil is too poor, chemicals can help improve it and grow bette

25、r crops, but this may damage or destroy land surrounding the farms. Instead, farmers should look for other methods. In the early 16th century, brothers Tan and Xiao Zao of Jiangsu Province cheaply bought fields along lakes nobody wanted because they were too wet. They built dikes around the fields t

26、urning the fields into fish ponds and they became fish farmers. They also planted fruit trees on the dikes and kept chickens and ducks. They were very successful farmers.Answers to Exercise 1: History of farming farmers in China Protection of nature trees Environmental problems dikesAnswers to Exerc

28、gue:A: Here we have a nice piece of land, and I think the best we could do is grow rice. Rice is an important product and we can make good money growing rice. Another reason why I think we should grow rice is that the soil is very good for rice and there is plenty of water for irrigation.B: Well, I

29、disagree. I think it would be wrong to grow rice. We should grow more sugarcane in our area, because sugarcane is easier to grow. There are plans to build a sugar factory near the town and that would bring many jobs to this region. Sugarcane can be grown without much work. There are already many ric

30、e farms in the area. Adding another sugarcane farm may make the factory owner decide to build his new factory here.A: Yes. I have heard about these plans, but its far from sure that the factory will be built here. If not, then the sugarcane must be transported to the next town, which would not be ve

31、ry good. As far as I can see the best thing to do would be to plant that field with rice.D: Well, I dont think any of you is right. We have to make a choice, and in my opinion we should raise pigs. Agricultural products such as sugarcane and rice are produced by many farmers around here. Therefore t

32、he prices are low. Wed better use the land to raise pigs.C: Wouldnt it be better to plant trees on the land because a lot of wood has been destroyed over the past forty years and we have to protect the environment. We should give something back to nature. Besides, we could cut down some bf the trees

33、 after a few years and sell the wood.D: No. That would be a, waste of ground and money. We have to make use of the land. The land area is too small for any real crop growing, and you would only be able to plant just a few trees. We have to make a choice. Pig raising doesnt need a lot of space and it

34、 can be a way to make a lot of money.A: You are right about the size of the land. There isnt much we can do with it because its too small. But I agree with C that the environment in our province has had a lot to suffer. Wouldnt it be better_ as C suggests to just leave that piece of land as it is, o

92、arnt the work on the farm from their parents. Sometimes, they were told about ways in which they could improve their farming. But if they lived in far off places or in the mountains, there were few opportunities to learn about better ways of farming.During the second half of the twentieth century, t

93、his situation was improved. Farmers were taught how to read and write. Books and magazines were published for farmers so that they could read about new methods of farming and improve their own situation. It also became possible for some farmers to experiment and share their results and discoveries i

94、n written reports with others. Still, not all farmers can read and write, but their number is getting smaller.To modernise and use new techniques, farmers have to be able to read and write. They must be able to read what is written on bags of fertilisers they buy, to know how to use them and how to

95、use them safely. They also have to be able to read the instructions on how to use new tools and machines. In the future, farmers will have to learn more to be able to use modem techniques such as greenhouses and GM.Many farmers take courses where they learn about new technologies in agriculture. The

I work on a fish farm.Rig

109、ht now Im feeding the fish, which are kept in cages in the sea. The cages are tied to the rocks on the j bottom of the sea. It can get very windy here. Twice a ! day I put the fish food in the boat and go out to the cages. The fish are always hungry!When the fish have grown to the right size, we pul

110、l the cages out of the water. The fish are killed and cleaned. Our fish farm is a long way from the nearest market. So we either freeze the fish or smoke them. We dont salt any fish here. Some fish farms do, but we dont.Three of us work here and theres always a lot to do. Inside that building over t

111、here we have tanks for the young fish. We produce all our own fish from eggs. The fish start to grow in fresh water. Then, when they are bigger they go into the sea, which is salty, of course.Theres always a lot of work to do: feeding the fish, cleaning the tanks, getting eggs out of the best of the

112、 large fish, harvesting the fish, cleaning them and smoking them. We burn our own wood and that way we get a very good strong smoke. Its more work, but we get higher prices for our smoked fish.Answers to Exercise 1:1 She is (probably) a fisherwoman.2 I think she is going to open the boxes and feed t

113、he fish. Or: I think she is on her way to the market to sell the fish.3 Without listening to the tape, you may have various answers. Sample answer:If you are a fisherman / woman you have to get up early every morning. The first thing to do is to go out in the boat and see if anything is caught in th

114、e nets. Next, you have to bring in the fish and throw out the nets for the next catch. Then, the fish must be brought to land. The fish should be kept in big boxes full of water, so they dont die.Answers to Exercise 2:1 We feed the fish twice a day.2 We produce our own fish from eggs in the tanks.Or

115、: We clean the tanks.3 We get the eggs out of the best of the large fish.4 When the fish are big enough, we put them in cages in the sea.S When the fish have grown to the right size, we harvest them, clean them, freeze them or smoke them.6 We take them by truck to the nearest market.Answers to Exerc

116、ise 3:1 The cages have to be tied to the bottom of the sea because it is windy.2 They freeze or smoke all the fish because the fishfarm is a long way from the nearest market.3 They bum their own wood because in that way theyget a good strong smoke.4 They smoke their fish themselves, because they get

117、higher prices for smoked fish.Step 3 Talking practiceSample dialogues:Dialogue 1:SI = Student 1: Pro because he/she thinks this is the best way to do it.S2 = Student 2: Con because he/she is a vegetarian S3 = Student 3: Pro because he/she is a farmer whothinks this is the best way.S4 = Student 4: Co

118、n because he/she thinks the animals should not suffer.SI: Well, I dont know so much about factory farms, but the fact is that more and more people want to eat meat, so we have to raise more and more farm animals for food. We must have factory farms to raise these animals.S2: People should eat less m

119、eat or should even try to eat as little meat as they can. Meat is not very healthy for people anyway. Thats why so many people get too fat in China.S3: I like eating meat; but I dont like the idea that the animals have a terrible life before they are killed for food. S4: It is not so easy. Raising f

120、arm animals takes up a lot of space. It is cheaper to have the animals close together, on what you call a factory farm. I need less land and fewer people to take care of the animals. Can you imagine how much time it would take us to look for eggs if I had 1O, OOO chickens running loose in my yard?S3

121、: China is a very big country. We have enough space and it would be better if more people found jobs feeding, taking care of the animals and collecting the eggs.S4: Thats just what you think. But you dont know much about farming, or you dont understand.S4: Im sorry. What I wanted to say is that it i

122、s true that China is a big country, but we cant build these buildings just about everywhere and besides, they should not be too far away from the farm. As a farmer I must be able to manage everything myself.SI: I agree. Farming is important to our economy, and China should not be dependent on foreig

123、n countries for food. What S2 says is not true. Of course we could eat other products instead of meat to get the protein we need. But then, farmers would have to grow more soy beans to produce tofu. Our country is big, but only 7% of the land can be used for growing crops. So it is better to use lan

124、d that is not arable to build factory farms that produce animal meat. That is our best source for protein.S3: But still we must find a solution for the factory farms. Too many animals suffer. When the animals suffer, the meat will not be as tasty as that from farm animals. Everyone knows that farm c

125、hickens are tastier than factory chickens.S2: Besides, the bio industry produces too much manure that is harmful to the environment.Dialogue 2:SI = Student 1: Will take over farm business but doesnt believe in progress.S2 = Student 2: Wants to take over farm business and believes in progress.S3 = St

126、udent 3: Believes in progress, but doesnt want to take over the farm.S4 = Student 4: Wont take over the farm business and doesnt believe in progress.S4: No. I dont want to take over the farm of my parents. I have seen enough of it. It is hard work and you cant earn much money. Even if modem ways of

127、farming made farming easier or better, success always depends on the weather. And a lot of hard work can be lost because of a dry summer, a storm or some other disaster. I want to study more so I can look for another job.S1: What S4 says about the weather is true. But there arent many other jobs in

128、our village. I dont want to move to a big city. I want to stay in our province, where all my friends and family are. I will take over the farm from my parents. It is hard work, but I know how to do it. Maybe learning something can help a little, but not much.S2: Well, I want to take over the farm fr

129、om my parents. But before that, I want to study more agricultural science. My father took a short course about new ways of fertilising and crop rotation a few years ago, and he learnt a lot from that. He also always reads the local magazine about new seeds and new kinds of fruit trees and so on. My

130、uncle wrote a book about growing grapes and my cousins are now making wine. They were the first in our village to do that, and now some other farmers want to try that as well.S3: I agree with that, but for myself I think farming is ajob that is too hard. I think a lot of improvement can be made, but

131、 still the work will be dirty and heavy, and you have to get up too early every day.S2: I dont think the work is dirty. Most materials are natural and you can take a shower when you are finished. It is much healthier than working in a factory where you get dirty with oil and breathe in dangerous smo

132、ke and gases.S1: Yes, but the work is heavy and there is always so much to be done. Its terrible. Sometimes you must work in the burning sun and sometimes in the rain, or worse.S2: But all that will improve. Growing crops in greenhouses is not only better for the plants, but also for the farmers. An

133、d much of the work can be done using machines.Dialogue 3:SI = Student 1: Is optimistic and thinks there are many opportunities.S2 = Student 2: Is pessimistic and thinks there are too many farmers in China.S3 = Student 3: Believes that farmers in China have no other choice. They must develop new prod

134、ucts.S4 = Student 4: Traditional. Thinks new product dont fit in with Chinese culture.S1: Welcome everybody to the discussion. Over the past 15 years many farmers have started new businesses growing different crops or doing other things on their farms. Many of them have been very successful.I think

135、it is great. Farmers have had traditional ideas about farming for too long. There was a time when everybody had the same type of life, and there were only few things to be bought in the shops. But as people have more money to spend, they like buying different products. So now, farmers can grow whate

136、ver they like.S2: Well, thats not true. They cant just grow whatever they like. Farmers can only grow products that people will buy. You cant start growing something that nobody wants.S4: True. Besides, in many places the land can only be used for some crops. And of course the climate does not alway

137、s allow growing what you want.S3: But farmers will have to. If everybody is growing the same few crops, the price will go down and farmers have no opportunity to make more money. Farmers must take a risk. You cant do any business without risk. Farmers will have to read newspapers and magazines to fi

138、nd out what people will want to buy. They should know enough about the land and agriculture to know whether they can grow new crops with success. Then, when they are the first to do something new, they must grab the opportunity.S2: Haha. That is only for the farmer who starts doing something. As soo

139、n as his neighbours see that he is successful, many others will follow. And very soon everybody in the region will be growing that crop. And what happens then? The prices will drop.SI: Well, farmers must know when to take risks. Many people think that there are no chances in farming, but there are.

140、In fact, there are many. The important thing is to make use of the opportunities.S3: Yes. Chinese farmers have many opportunities togrow new crops and produce new products, not only for changing markets in China, but also for the export market.SI: Yes. And that creates even more opportunities.Step 4
