Paragraph 3
• What are mainly talked about Yuan Longping? • his hobbies and view of live
Paragraph 4
• Just dreaming for things, however, costs nothing. Long ago Dr yuan had a dream about rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Dr Yuan awoke from his dream with the hope of producing a kind of rice that could feed more people. Now, many years later, Dr Yuan has another dream: to export his rice so that it can be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people.
is to work the land to do research to increase the out put of rice.
Paragraph 2
• Born in a poor farmer's family in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in many parts of the countryside. Dr Yuan searched for a way to increase rice harvests without expanding the area of the fields. In 1950, Chinese farmers could produce only fifty million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests mean that 22% of the world's people are fed from just 7% of the farmland in China. Dr Yuan is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tools in the battle to rid the world of hunger. Using his hybrid rice, farmers are producing harvests twice as large as before.
Paragraph 2
• What was his ambition? why? • His ambition was to produce enough rice to feed people
because hunger was a global issue.
Paragraph 3
• Dr Yuan is quite satisfied with his life. However, he doesn't care about being famous. He feels it gives him less freedom to do his research. He would much rather keep time for his hobbies. He enjoys listening to violin music, playing mah-jong, swimming and reading. Spending money on himself or leading a comfortable life also means very little to him. Indeed, he believes that a person with too much money has more rather than fewer troubles. He therefore gives millions of yuan to equip others for their research in agriculture.
Paragraph 4
• What are Yuan longping’s dreams? • One of his dreams is to produce a kind of rice
that could feed more people. Another one is to export his rice so that it can be grown around the world.
To rid the India of hunger, the Indian government decided to cut down the export of rice. Facing the
problem, people in India only have two meals one day.
feed the large population in China as well as in the world.
Yuan Longping annouced to the world that China could solve the problem and and help to solve the problem for the world.

Yuan Longping put an end to hunerParagraph 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. Dr Yuan Longping grows what is called super hybrid rice. In 1974, 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 one-third more of the crop in the same fields. Now more than 60% of the rice produced in China each year is from this hybrid strain.

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.Period 2 ReadingStep 1 Lead-in..

This special strain of rice makes it possible to produce one -third more of the crop in the same fields.e.g: That made it possible for life to begin to develop.The development of science makes it possible for us to know more about the universe.11. Dr Yuan awoke from his dream with the hope of producing a kind of rice (that could feed more people).e.g: He went to the U.S with the hope of finding a better job there.Step 6Closing down by having a dictationTo end the peri od you will take a dictation. It is about Yuan Longping, “Father of Super hybrid rice”.Yuan Longping, China's Most Famous "Farmer"Yuan came up with the idea of hybridizing rice for the first time in the world in 1960s. Since then, 50 percent of China's total rice cultivation fields have grown such rice, which added some 300 billion kilograms to the country's grain output. Furrows grown on his sunburnt face, a slim figure and coiled-up trousers legs would confuse foreign reporters who came to interview themost famous scientist in China, who would rather be called “a farmer”. Indeed, like many Chinese farmers, Yuan in his 70s and has devoted most of his life growing rice in paddy fields, but unlike those farmers, he reaps the seed from experimental fields only for hybridizing rice.Unit2 Working the landListening, Speaking and WritingLearning AimsTo help students read the passage Organic Farming.To help students to use the language by reading, listening, speaking and writing.ProceduresI．Warming up by listening and reading aloudLanguage is created to be listened to and spoken first.

新人教版 Book 4 Unit 2 Working the Land 课文
Unit 2 Working the landPart I a Pioneer for all PeopleAlthough he is one of China’s most famous scientists, Yuan Longping consider s 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 struggle d for the past five decade s. Dr Yuan Longping grows what is called super hybrid rice. In 1974, 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 one-third more of the crop in the same field s. Now more than 60% of the rice produced in China each year is from this hybrid strain.Born in 1930, Dr Yuan graduate d from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in many parts of the countryside. Dr Yuan search ed for a way to increase rice harvest s without expand ing the area of the fields. In 1950, Chinese farmers could produce only fifty million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produce d. These increased harvests mean that 22% of the world’s people are fed from just 7% of the farmland in China. Dr Yuan is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tool s in the battle to rid the world of hunger. Using his hybrid rice, farmers are producing harvests twice as large as before.Dr Yuan is quite satisfied with his life. However, he doesn’t care about being famous. He feel s it gives him less freedom to do his research. He would much rather keep time for his hobbies. He enjoy s listening to violin music, playing mah-jong, swimming and reading. Spend ing money on himself or lead ing a comfortable life also means very little to him. Indeed, he believe s that a person with too much money has more rather than fewer trouble s. He therefore gives millions of yuan to equip others for their research in agriculture.Just dream ing for things, however, cost s nothing. Long ago Dr yuan had a dream about rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Dr Yuan awoke from his dream with the hope of producing a kind of rice that could feed more people. Now, many years later, Dr Yuan has another dream: to export his rice so that it can be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people.Part II Chemical or Organic Farming?Over the past half century, using chemical fertilizers has become very common in farming. Many farmers welcome d them as a great way to stop crop disease and increase production. Recently, however, scientists have been finding that long-term use of these fertilizers can cause damage to the land and, even more dangerous, to people’s health.What are some of the problems caused by chemical fertilizers? First, they damage the land by kill ing the helpful bacteria and pests as well as the harmful ones. Chemicals also stay in the ground and underground water for a long time. This affect s crops and, therefore, animals and humans, since chemicals get inside the crops and cannot just be wash ed off. These chemicals in the food supply build up in people’s bodies over time. Many of these chemicals can lead to cancer or other illnesses. In addition, fruit, vegetable s and other food grown with chemical fertilizers usually grow too fast to be full of much nutrition. They may look beautiful, but inside there is usually more water than vitamin s and mineral s.With these discover ies, some farmers and many customer s are beginning to turn to organic farming. Organic farming is simply farming without using any chemicals. They focus on keeping their soil rich and free of disease. A healthy soil reduce s disease and helps crops grow strong and healthy. Organic farmers, therefore, often prefer using natural waste from animals as fertilizer. They feel that this makes the soil in their fields richer in minerals and so more fertile. This also keeps the air, soil, water and crops free from chemicals.Organic farmers also use many other method s to keep the soil fertile. They often change the kind of crop in each field every few years, for example, growing corn or wheat and then the next year peas or soybeans. Crops such as peas or soybeans put important mineral s back into the soil, making it ready for crops such as wheat or corn that need rich and fertile soil. Organic farmers also plant crops to use different level s of soil, for example, planting peanuts that use the ground’s surface followed by vegetables that put down deep root s. Some organic farmers prefer planting grass between crops to prevent wind or water from carry ing away the soil, and then leaving it in the ground to become a natural fertilizer for the next year’s crop. These many different organic farming methods have the same goal: to grow good food and avoid damaging the environment or people’s health.。

A PIONEER FOR ALL PEOPLE造福全人类的先驱者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. 尽管他是中国最著名的科学家之一，袁隆平仍然认为自己是个农民，因为他在田间耕作，进行科学研究。
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. 的确，他那被太阳晒得黝黑的脸和手臂，以及他那消瘦而结实的身躯，就跟其他千百万中国农民一样。
过去50年来他一直在努力帮助他们。
Yuan Longping grows what is called super hybrid rice.袁隆平种植的是被称为“超级杂交水稻”的稻种。
In 1973, he became the first agricultural pioneer in the world to grow rice that has a high output. 1973年他成为世界上第一位种植高产水稻的农业先锋。
This special strain of rice makes it possible to produce 20% more of the crop in the same fields. 这种特殊的稻种使得同样的田地多收获20%的产量。
Now more than 60% of the rice produced in China each year is from this hybrid strain.如今中国每年生产的稻米60%以上出自这种杂交稻种。
