Although（）he is one of China's most famous scientists, Yuan Longping c 1 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 d 2 . 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 s 3 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 p 4 in China each year is from this hybrid strain.

Born( ) in 1930, Dr Yuan g 5 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 o 6 At that time, hunger was a d 7 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 i 8 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.（）

Dr Yuan is quite s 9 with his life. However, he doesn't care about （）being famous. He feels it gives him less f 10 to do his research. He would much rather（）keep time for his hobbles. He enjoys listening to violin music, playing mah-jong, swimming and reading. Spending money on himself or leading a c 11 life also means very little to him. Indeed, he believes that a person with too much money has more rather than （）fewer troubles. He t 12 gives millions of yuan to equip others for their research in a 13 .

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 fee more people. Now, many years later, Dr Yuan has another dream: to e 14 rice so that it can be grown around the g 15 . One dream is not always enough, especially( ) for a person who loves and cares for his people.
