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.。

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 Y uan 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. Step 5 课后反思：Period 2 ReadingStep 1. Lead-in.

Closing down by having a dictationTo end the period 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, aslim figure and coiled-up trousers legs would confuse foreign reporters who came to interview the most 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.Step 3 课后反思：Period 4 Listening, Speaking and WritingLearning Aims：To help students read the passage Organic Farming.To help students to use the language by reading, listening, speaking and writing.Teaching Procedures：Step 1.
