　　　　　　　　　　　　　　　 A PIONEER FOR ALL PEOPLE

　　　 He wants everyone to call him a farmer,for that’s how he regards himself. Although he is one of China’s most famous scientists, Yuan Longping 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 other Chinese farmers. In many ways , he is one of them , and he has struggled for the past five decades to help them. Dr Yuan 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.

　　　 Born into a poor farmer’s family in1931, Dr Yuan graduated from Southwest Agriculture College in 1953.Since then , he has devoted his life to finding ways to grow more and more rice. As that time , hunger was a serious problem in many parts of the countryside. Dr Yuan searched for a way to increase rice harvests without expanding the area of fields. In 1950, Chinese farmers could only produce five and a half billion tons of rice .Last year, however, nearly twenty billion 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 other less developed countries to increase their rice harvests.Thanks to his research , the UN is trying to rid the world of hunger. Using his hybrid rice farmers are producing harvests twice as large as before .

　　　 You might guess that Dr Yuan , who is now rich and famous , is satisfied with his life. However , he cares little about spending the money on himself or leading a comfortable life. Indeed, he believes that a person with too much money has more, rather than fewer troubles. So he gives millions of yuan to equip others for their research　 in agriculture. He also doesn’t care about being famous .He feels it gives him less freedom to do his research .And he would rather keep time for his hobbies. Although 　he can no longer play his violin, he still lisens to violin music. His other hobbies include playing mah-jong, swimming and reading. He used to walk to his rice fields twice a day ,but now he prefer to ride his motorcycle.

　　　 Wishing for things, however, costs nothing. Long ago, in a dream, Dr Yuan saw 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 Dr Yuan has another dream: to export his rice so that it can be grown all over the world. As Dr Yuan proves,one dream is not always enough, especially for a person who loves and cares for his people.
