II. Fast-reading
Find out the main idea of each paragraph.
Paragraph 1 Although he is one of China's most famous scientists, Yuan Longping considers himself a farmer, for he works the land to do his research. Indeed, his sunburnt face and arms and his slim, strong body are just like those of millions of Chinese farmers, for whom he has struggled for the past five decades. Yuan Longping grows what is called super hybrid rice. In 1973, he became the first agricultural pioneer in the world to grow rice that has a high output. This special strain of rice makes it possible to produce 20% more of the crop in the same fields. Now more than 60% of the rice produced in China each year is from this

Unit2 Working the landPeriod 1 Warming up and pre-reading.Step 1 Lead-in.Poem By Li ShenFarmers weeding at noon,Sweat down the field soon.Who knows food on a tray,Due to their toiling day.Then let one student recite the poem in Chinese.Step 2 Warming up by questioningHello, everyone. We shall read about man who works the land today. Have you ever grown any plants? If not, what kind of plant would you like to grow? How will you grow it?(For reference: Mr. Li, I worked with my father in the rice field last year. We grow hybrid rice and use animal wastes to make the soil rich.)Has anyone of you ever been to the countryside? What did you do there?(For reference: I went to Chuankou the day before yesterday. It is a small mountain village 75 li n orth of Beijing. I went there to visit my uncle’s family. I like that small beautiful village very much. )Who are from a farmer’s family? What do you know about farming?Step 3 Pre-reading and talkingQuestioning and answeringRice is main food in South China. What do you think would happen if tomorrow there was suddenly no rice to eat?(For reference: Then the south people would have to change their eating habit. They could turn to potatoes, wheat flour, cow and sheep cheese, cabbage, onions and garlic for food. They are the bases of the traditional food in North China. )If you had the chance to do one thing to help end hunger in the world, what would you do?(For reference: I would try to end hunger by popularizing the advanced farming techniques. Modern techniques could be introduced to increase the rice output, and expand the area of fields.)Giving background information about Professor Yuan LongpingHave you ever heard of a man called Professor Yuan Longping? Would anyone of you tell the class something about him?(For reference: Professor Yuan Longping is a Chinese agricultural scientist. Professor Yuan's breakthrough scientific achievement led to the world's first successful and widely grown hybrid rice varieties, revolutionizing rice cultivation in China and tripling production over a generation. His approach to rice breeding then spread internationally throughout Asia and to Africa and the Americas, providing food for tens of millions and leading to his becoming known as the "Father of Hybrid Rice."Step 4. ReadingReading aloud to the recordingComprehension—understanding what you are reading—is important. To read in thought groups is an easy, yet effective, way of improving reading comprehension. Now turn to page 9 and read aloud to the recording of the text A PIONEER FOR ALL PEOPLE. Pay attention to the thought groups in the sentences while listening and reading aloud.A brief introduction:Yuan Longping is known as China’s “father of hybrid rice”. It’s said that in China, we eat depending on “Two Ping” ---- Deng Xiaoping, who made the policy of System of Production Responsibility, & Yuan Longping, who invented hybrid rice.Yuan Longping, who was born in September, 1930, graduated from Agriculture Department in Southwest Agricultural Institute. He has been working on agriculture education & the research into hybrid rice since he left the institute.In the 1960s, when China was suffering from serious famine, he came up with the idea of hybrid rice, which has a high yield ( or output). Ten years later, he succeeded in inventing a new species that produced a 20 percent higher yield than common types of rice.Yuan devoted himself to the research into agriculture, & was honored by UNESCO & FAO(联合国教科文组织）. Although he is 74 years old, he is still working on the research into agriculture.。

Nowadays，the increase in the prices of agricultural products is one of the greatest concerns of the people and the government.The government has announced a series of policies(政策) to prevent the prices from rising further.Rising housing price is still a big concern for the people，but since farm products are needed every day，the increase in their prices has made life very difficult for the people.Many people may think the increase will help farmers.But have higher prices of farm products really benefited the farmers?Take the increase in vegetable prices in the first half of this year for example.Though natural disasters such as droughts and spring frost did not cause the prices of farm products to increase greatly—in fact，prices of some products did not increase at all—vegetables have become dearer by as much as 20 percent compared to that of last year.This means only a small part(or even none) of the extra money that city people have paid to buy farm products has gone to the farmers.The extra cost actually has gone to middlemen.As the fact shows，just increasing prices of farm products will have a negative influence on the entire economy.On the one hand，the price increase has created some abnormal phenomena，which hurt farmers' interests.On the other hand，resources will enter the agriculture because of the high price of farm products，which would finally create negative effects on the whole economy.In such a case，it would be better to leave the market to decide the prices insteadof raising farm products' prices to protect the interests of farmers.Actually，such a way will be better for farmers in the long run.根据文章内容判断正(T)误(F)。
