(one student reads one paragraph, another

(all the following paragraphs like this) Paragraph1.

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.

2. .Chinese farmers, for whom he has struggled for the past five decades.

3.Dr Yuan Longping grows what is called super hybrid rice.

4. he became the first agricultural pioneer in the world to grow rice

that has a high output.

5.This special strain of rice makes it possible to produce one-third more of the crop in the same fields.

6.more than 60% of the rice produced in China each year is from this hybrid strain Paragraph2. Born in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953.

Since then, finding ways to grow more rice has been his life goal.（have done...since）As a young men ,he saw the great need for increasing

the rice output .At that time ,hunger was a

disturbing（令人不安的，disturbed 感到不安的）

problem in many parts of the countryside .Dr Yuan searched for （寻找）a way to increase rice harvests without expanding （without doing）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（to do 作目的状语）

their rice harvests. Thanks to （幸亏，多亏了）his research, the UN has more tools in the battle to rid the world of hunger. Using （与farmer构成主动关系）his hybrid rice, farmers are producing harvests twice as large as before.（as+adj./adv.+as）

Paragraph3. 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 trouble. He therefore gives millions of yuan to equip others for their research in agriculture. Paragraph4.（let students solve the following problems) Just dreaming for thing, however, costs nothing. Long ago Dr Yuan had a dream about rice plants as tall as sorghum. Each era of rice was as big as an ear of corn and each grain of rice as huge as a peanut. Dr Yuan awoke from 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.
