Step I Revision T: Have you read the reading on Page 87? Ss: Yes. T: Very good! Now answer the questions above the passage. I will ask three pairs to do the asking-and-answering activities. One read out the question and the other answer it. Volunteer?

S1: What achievements does the World Food Prize honor? S2: It honors human development in improving the quality, quantity or availability of

food in the world. S3: Who won the award in 2004? S4: Yuan Longping from China and Monty Jones from Sierra. S5: Why are their achievements outstanding? S6: They both work in the development of new hybrid rice plants that produce higher yields. Individually, Yuan Longping’s breakthrough makes crop yields 20% higher. Today almost half of China’s rice production is from this hybrid plants and they produce enough food for about 60 million more people every year. In 1991 he created a rice hybrid that is particularly well suited to Africa’s poor land and dry weather and that produces higher yields than other local rice. It also produces stable rice of better quality.

T: OK. Turn to Page 88

, look at Part 10. I’ll read the definitions and you say the words with your books closed.

T: An important substance in food.

Ss: Protein.

T: Together.

Ss: Jointly.

T: To help or give an advantage. Ss:

benefit . T: For sale. Ss: Commercial. T: Ten years. Ss: Decade. T: Check the answers of Part 11 on Page 88. Show the correct answers on the screen for the students to check.

Step II Warming up

T: Do you have a general idea about Yuan Longping? Ss: Yes, a little. T: Have you finished reading the text on Page 32 and doing Part 2 on the same page? Ss: Yes, of course. T: Now you have got a general idea about the great scientist —Yuan Longping. Today we are going to comprehend the passage about him.

Step III Reading Scanning Get the Ss to comprehend the passage quickly and accurately and meanwhile help the Ss to form a good habit of reading. Teacher gives the Ss 4 minutes to look through the whole passage. Tell the Ss to read the text silently to get the general ideas of the passage. Encourage the Ss to express their different opinions in English. Different answers and opinions are available.

T: Look at the title of the reading passage. What do you think it is about? Please read the passage and tell if the title of the passage is suitable. If not, write a new one and give the reasons. You can talk about you new title and the reason with your partners. 4 minutes for the students to finish the task. T: Are you finished? Ss: Yes. T: OK, I’ d like several of you to present your new titles and your reasons.

Sa: In my own opinion, the title should be about the student’s life of the character, while the passage is mainly about professor Yuan’s scientific research and his outstanding achievements in hybrid rice and there is only a little part about his school life. So I think it isn’t suitable and my new title is A Great Scientist in Agriculture.

T: A good job! Any other ideas?

Sb: I’m not satisfied with the title given in our textbook. My new title is The Father of Hybrid Rice. In my opinion, the title should be about a hard working student. But

the passage is mainly about Professor Yuan’s achievements --- hybrid rice. There is only a nickname about his asking questions, so the title isn’t suitable.

Sc: My new topic is an Outstanding Chinese Scientist.

Sd: My new topic is a Leading Figure in the Rice-Growing World. T: All right! I think most of you have the similar opinion, although you have different new titles. That’s OK.

Skimming In this part, Ss will read the text again and then work together with their partners to answer some questions that teachers show on the screen about the passage. Give them a few minutes to find out the answers and talk about them with their partners. Check the answers with the whole class. T: Please read the passage again and try to find out the answers to the questions on the screen. At the same time underline the new words and expressions you are not familiar with or you have any difficulty in understanding.

1. What kind of student was Yuan Longping when he was young? 2. Why is he the leading figure in the rice-growing world? 3. What did he discover? 4. How important is the discovery? 6 minutes for the students to find out the answers to these questions and talk about them with their partners. T: Time is up. Have you finished the task? Ss: Yes. T: Who would like to answer the questions? Volunteer? S1: Professor Yuan was a hard-working student with lots of questions and he was interested in plants.

S2: Because he discovered a naturally sterile male rice plant that was a breakthrough. Professor Yuan has shared his knowledge and technology with foreign scientists, providing them with crucial breeding materials for the commercial production of hybrid rice in their respective countries. Farmers in more than ten other countries

besides China, including the United States, have benefited from his work. S3: He discovered a new kind of hybrid rice by crossing different species of rice plants and this new plant not only give a higher yield but also produces rice more quickly. S4: As a result of Yuan Longping’s discoveries Chinese rice production rose by 47.5 percent in the 1990’s. Professor Yuan’s pioneering research has helped transform China from food deficiency to food security within three decades. He spreads his techniques for hybrid rice throughout Asia and to Africa and America and trains thousands of scientists and researchers from over 25 countries. Explanation T: Now let’s deal with some language points. Turn to Page 32. Let’s look at the sentences:

1. In the rice-growing world, the Chinese scientist, Yuan Longping, is a leading figure.

In this sentence, “Yuan Longping” is used as appositive.

eg. Shanghai, an international commercial city, lies on the east coast of the Pacific Ocean. 2. He thought there was only one way to do this———by crossing different species of rice plant, and then he could produce a new plant that could give a higher yield than either of the original plants.

This sentence is long, so we should learn how to analysis this kind of long, different and complex sentences to comprehend the passage. 3. As a result of Yuan Longping’s discoveries Chinese rice production rose by 47.5 percent in the 1990’s.

1) as a result of

= because of

= thanks to = owing to = due to 2) rise vi. → rise by =increase by; “by” means “to the extent of”.

eg.

The bullet missed me by two inches.

It needs to be longer by two feet. 3) “In the 1990’s” can also be written as “in the 1990s”.

Step IV Discussion

First ask the students to read the passage silently by themselves and then to discuss with their partners to make an interview. The topics will be shown on the screen.

At last ask several groups to act it out. T: Now please read the passage again and then we’ll have a discussion about the hybrid rice. Look at the screen, please. Discussion in groups of three to make an interview:

Suppose one of you is a sixty-year-old farmer who has been growing rice; One is professor Yuan and the other one is a CCTV reporter. Please talk about the influence of the new hybrid rice. First you can complete the following table as a guide.

Reference form about the interview Figures The farmer In the past poor... hard life Nowadays In the future encourage grandsons to study... Professor Yuan a dream... be develop...spread...train...new species future projects. starvation... rich...enough food...happy life interested in...experiment...research Reach... over 800 kg / mu

First give several minutes for the students to prepare ,then ask three pairs to act it out. T: I’d like one group to come to the blackboard to act your interview out. Volunteer? (Reporter=R; Mr. Li=M; Professor Yuan=Y) R: I’m honored to interview you, Professor Yuan. You are so famous that almost all the Chinese know you for your name can be learnt in our textbook. By the way, this is Mr. Li, who has benefit from your hybrid rice for many years. M: How do you do? Professor Yuan, I’m so happy to know you today. I have been hoping to say “Many thanks” to you face to face for almost thirty years. Today I

realize my dream at last. Y: Glad to know you, too. My dream is that I can cultivate rice as plump as peanuts, and farmers can relax in the cool shadow of big rice plants. Since then, I have devoted myself to the research and development of a better rice breed. I’m very happy to do something for our country. I’m interested in plants when I was young. R: As we all know, with the development of science and technology, our living standard is getting better and better. Can you tell us something about the life in the past?

M: In the old days, even in the first twenty years after China was founded, the land was very poor, so there was seldom enough food to eat. What’s worse, there were bad years now and then. Peasants are poor and led a hard life.

Y: I came up with an idea for hybridizing rice in the 1960s, when a series of natural disasters and inappropriate policies had plunged China into an unprecedented famine that caused many deaths. It took me many years to cultivate a type of hybrid rice species in cooperation with others. After all it was a breakthrough. R: What’s about your life and research today? Y: Luckily for me, I was given the 2004 World Food Prize. I am devoting myself to my study now. And I am helping other Asian countries to produce more rice. M: Great changes have taken in our life. The yield of our rice almost doubled. We are leading a happy life. My grandson is a senior middle school student, so I hope he can do agricultural research and make contributions to the farmers. All roads lead to Rome. Professor Yuan is compared to a farmer. He is also respected all over the world. Y: My second target is to reach an annual yield of over 800 kilograms per mu. I has set the year of 2005 as the deadline for this goal. R: May you achieve your goal soon. Thank you very much for the interview! T: Thank you for your excellent work, too. Time is limited you can practise the interview after class.
