By reading they will realize the role that agriculture plays in human life. In fact this world faces a serious problem-starvation.

        Have you ever grown any plants? If so, what did you do to grow them? If not, what kind of plant would you like to grow? How will you grow it?

        Step 3 Pre-reading

        The purpose of this step is to let students know the importance of rice. By answering the two questions, students can easily understand why we call Dr Yuan Longping a pioneer for all people, and why he devotes all his life to the rice research.

        1.What do you think would happen if tomorrow there was suddenly no rice to eat?

        2. If you had the chance to do one thing to help end famine in the world, what would you do?

        Step 4 Fast Reading

        The purpose of fast reading is to let students find some useful information, and get familiar with the text. So in this step, teacher designs some questions for students, so that they can easily find the answers and finish the reading task.

        1. What does Dr Yuan look like?

        2. What’s his achievement?

        3. What do you think of him?

        At first, let students listen to the tape, and then finish the exercise in Comprehending. In Step IV and V, we have involved some questions in Exercise 3, so teachers can choose some questions to do. For Exx 1 and 2, teachers can leave some time for students to finish and then check the answers with the whole class.

        Step 6 Summary and Homework

        Today we talked about agriculture. And we also read about Dr Yuan Longping. We have known much about the great scientist. OF course we have learned some words and expressions about farming. Please try to grasp these words and expressions after class. Now please look at the poem on the screen:

        Farmers weeding at noon,

        Sweat down the field soon.

        Who knows food on a tray,

        Due to their toiling day.

        Do you know it? Read it and say whot does it mean?

        (It’s 憫農(nóng) written by Li Shen.)

        The title is A HARD-WORKING FARMER. This is my gift to you. Please read it together. OK, hope you can remember it when you are having your dinners. Besides, I’d like you to think: even if Dr Yuan’s dreams come true, can this really solve the starvation? Why? This is the homework. Think it over. Next time I’ll ask some of you to give your opinion in the class. Another one is to finish the exercises in learning about Language. Exercise 1,2 and 3 are about useful words and expressions. Finish them.

        A.Teaching important and difficult points

        1. To understand what they read.

        2.How to find reasons to persuade people to believe what they say. 3.How to write an attractive poster.

        B.Teaching methods

        Reading, speaking ,discussing and writing.

        C.Teaching aids

        A projector and a recorder.

        D.Teaching procedures & ways

        Step I Lead-in

        There are three main tasks in these period.

        1. Deal with the reading. Speaking and Writing on Page 15.

        2. Do SPEAKING AND WRITING TASK on Page 53.

        3. Finish TALKING on Page 48

        Step Ⅱ Reading

        1.This is the first step of Reading, Speaking and Writing. In the three steps, teacher should remind students the following: for reading, they should get the key words of the passage, in order to get a good understanding and make a good base for the writing; for speaking, they should attend to what they will do. Be careful not be off the point; for writing ,the most important thing is to practise writing using phrases, instead of the whole sentences. Give students a minute to read it and then show a chart on the screen to let them make sure the important points of this passage.

        Advantage:

        1. Healthy and safe

        2. Free of chemical fertilizers

        3. Grown away from industrial areas

        4. Away from dirty water supplies Disadvantage:

        1. People don’t know about the food and how good it is

        2. More expensive than other food which is not so safe

        Read Exercise 2 and then finish the task with the words and expressions below. Make sure that all that the students say is to persuade people to buy their food! So please don't be off this point. Give students some time to do this.

        Step Ⅲ Speaking

        Three minutes later, teacher can collect students' ideas. There are two kinds of ways to do this task. One is the seller's speech; he other is dialogue between two students. Students can choose either of them to practise the phrases below.

        Step Ⅳ Writing

        In this part the students should not use the whole sentences, using phrases or notes is OK. Ask students to read the instructions, and the example on Page 16 carefully. And then write down their poster.

        Give students three minutes to practise. And give them enough help, if some of them need it. Three minutes later teacher can ask one or two pairs of students to-act out their dialogues.

        Main heading

        This explains that you sell green food.

        Reasons to buy

        1. ( one reason )

        2. ( one reason )]

        3. ( one reason )

        4. ( one reason )

        Why it is good value. Buy the best fruits here

        We only sell green food in this shop!

        Best choice at best price!

        Safe, healthy, clean, fresh. Far away from any pollution.

        1. No chemical fertilizer, all organic fertilizers

        2. Clean air, clean water

        3. No poison, no pesticides

        4. Home in heaven

        Healthy food means healthy life. Far away from diseases, without worries, full of happiness. ( one reason )

        Step V Talking

        The purpose of this task is to let students practice how to persuade others, using some useful expressions below the instructions. There are two points that students should pay attention to. One is that they must know what is the subject they will talk about; the other is that they should use the expressions to practice presuasive skill. So, there are two tasks to finish the talking. First, teacher should help the students to remember who is Leng Jianli and what did she do. Second, ask the students to practice.

        the chart will give you more information about Leng Jianli. Maybe it is useful to your talking.

        What Leng Jianli did

        ● Plant trees, bushes and other plants in the desert near her farm.

        ● Carry water from far away and take very good care of them.

        ● Have been working very hard for many years.

        ● Turn desert into farmland.

        Read the instructions in Talking on Page 48.

        Step Ⅳ Speaking and Writing Task on Page 53

        If time permits, teacher can do the "Speaking and Writing task on Page 53 in this period, or leave it as homework.

        Sample writing:

        A fish farm is a pond or cage in the sea where farmers raise fish. In this case farmers can help fish grow faster to be big enough. This summer holiday I'm going to visit a fish farm near Yingshan lake.

        A fish farmer has to be careful when he keeps fish in a pond .He must keep the water of the ponds from becoming too dirty. He also is to keep fish very close together.

        What I am most interested in is to feed fish. I think fish must be fed regularly--twice or three times a day. I enjoy the scene in which fish jump up to take food. Besides feeding, the other task I have to do is to try to stop fish being affected by disease. I understand that fish disease are a serious problem. If that happened, all the fish in the pond would die. So I have to examine fish for disease. If so,I have to give some medicine to the fish.

        I imagine I'll be busy on a fish farm and have a good time.

If there are some problems, teacher can ask student to discuss and give them some suggestions to solve them.

        Step II Summary

        1.Fill in the chart on Page 16 to sum up what we have learned in this unit.

        SUMMING UP

        Write down what you have learned about working the land.

        We have learned about agriculture and deeds of Dr Yuan Longping. We also know what organic farming is and grasp how to express our ideas and write a poster.

        From this unit you have also learned:

        Useful verbs: expand export circulate rid…of reduce struggle equip

        Useful nouns: hunger bacteria fertilizer mineral supply level

        Useful adjectives and adverbs: super sunburnt satisfied fertile organic

        Other expressions: would rather lead a…life refer to year after year

        New grammer item: the –ing form used as the subject and object

        Step III Project

        As for project on Page 54.teachers can ask the students to choose three kinds of crops and refer to some books to find out where they are grown. Students may be asked to make a booklet after class and display it on the classroom wall for the rest of the class to enjoy. The contents of the booklet include if they can be grown in different climate and countries and where they cannot be grown.

        Here are some information for them to refer to::

        Cucumbers are grown for eating fresh or preserving as pickles. They must be grown in warm temperatures and full sunlight, and will not stand frost. Cucumbers mature quickly and are best suited to large gardens but can be grown in small areas if caged or trellised.

        Cucumbers do best in loose, sandy loam soil but can be grown in any well drained soil. Remove rocks, large sticks and trash before preparing the soil. Leave fine pieces of plant material such as dead grass and small weeds. They will help enrich the soil when turned under. Spade the soil to a depth of 8 to 12 inches. This is about the depth reached by most shovels or spading forks. Turn each shovel of soil completely over so all plant materials are covered with soil.

        Tomatoes are warm season plants requiring at least six hours per Temperatures are very important. Most varieties of tomatoes will not set fruit unless the average nighttime temperature stays above 55degrees. If nighttime temperatures are expected to drop below 55 degrees, protect the plants using a polyethylene film.

        One of the most common problems with tomatoes is called blossom end rot which appears as a gray or dark leathery scar or rot on the blossom end of the fruit. It can also be caused by a lack of calcium in the soil. Another common problem of tomatoes is blossom drop. This can occur if nighttime temperatures drop below 55 degrees and plants are not protected. Germination and tube growth are so slow that the blossoms drop off before they can be fertilized.

        Peas are a frost-hardy, cool-season vegetable that can be grown throughout most of the United States, wherever a cool season of sufficient duration exists. For gardening purposes, peas may be classified as garden peas (English peas), snap peas and snow peas(sugar peas). Garden pea varieties have smooth or wrinkled seeds. The smooth-seeded varieties tend to have more starch than the wrinkled-seeded varieties. The wrinkled-seeded varieties are generally sweeter and usually preferred for home use. The smooth-seeded types are used more often to produce ripe seeds that are used like dry beans and to make split-pea soup. Snap peas have been developed from garden peas to have low-fiber pods that can be snapped and eaten along with the immature peas inside. Snow peas are meant to be harvested as flat, tender pods before the peas inside develop at all. The Southern pea (cowpea) is an entirely different warm-season vegetable that is planted and grown in the same manner as beans.

        Step IV Checking yourself

        This is a chance for students to collect knowledge they have learned in this unit. Teacher can give the students some time to discuss it and then finish the questions in the chart. Doing this task can improve students ability of teaching by oneself.

        Step V Homework

        1.Preview the next unit

        2.Show the students some English farming proverbs and ask the students learn them by heart:

        He who does not rise early never does a good day’s work.

        起床不早,一天的工作干不好。

        Go to bed with the lamb and rise with the lark.

        隨羔羊就寢,與云雀同起。

        A barley-corn is better than a diamond to a cock..

        對一只公雞來說,一顆麥粒優(yōu)于一顆鉆石。

        The cuckoo comes in April, and stays the month of May; sings a song at Midsummer, and then goes away.

        布谷鳥,四月來,五月一直在,仲夏唱歌,然后就離開。

        Always take out the meal-tub, and never putting in, soon comes to the bottom.

        取糧不儲糧,桶底糧光光。

        No mill, no meal

        不磨面就沒飯吃。
