Yuan Longping, known as the “father of hybrid rice”, is one of China’s most famous scientists. Yet, he consider   1   (him) a farmer because he continually works the land in his research. Indeed, his slim   2   strong body is just like that of millions of Chinese farmers,   3   whom he has devoted his life.
Yuan Longping was born in 1930 in Beijing. His parents wanted him   4   (pursue) a career in science or medicine. However,   5   concerned him most was that farmers often had poor harvests and sometimes even had a serious   6   (short) of food to eat. To tackle this crisis, he    7   (choose) to study agriculture and received   8   education at Southwest Agricultural College in Chongqing.
After   9   (graduate) in 1953, he worked as a researcher. Yuan Longping realized that larger fields were not the   10   (solve). Instead, farmers needed to boost yields in the fields they had. How this could be done was a   11   (challenge) question at the time. Yuan   12   (convince) that the answer could be found in the creation of hybrid rice. A hybrid is a cross between two or more   13   (variety) of a species. One characteristic of hybrid is that they usually attain a   14   (high) yield than conventional crops. However,   15   it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate. The common   16   (assume) then was that it could not be done. Through intense effort, Yuan   17   (overcome) enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974. This hybrid enabled farmers   18   (expand) their output greatly.
Today,   19   is estimated that about 60 percent of domestic rice   20   (consume) in China is comprised of crops   21   (generate) from Yuan’s hybrid strains, and his strains have allowed China’s farmers to produce around 200 million tons of rice per year, Yuan’s   22   (innovate) has helped feed not just China,   23   many other countries that depend on rice as well, such as India and Vietnam. Because of his invaluable   24   (contribute), Yuan Longping has received numerous awards both in China and abroad.
  25   (give) that Yuan’s hybrids have made him quite wealthy, one might think he would retire to a life of leisure. However, this is far from   26   case. Deep down, Yuan is still very much a farmer at heart. As a man of the soil, he cares little for celebrity or money. Instead, he makes large   27   (donate) to support agricultural research.
  28   impresses people most about Yuan Longping is his ongoing ability to fulfil his dreams. Long ago, he envisioned rice plants as tall as sorghum,   29   each ear of rice as big as a broom, and each grain of rice as huge as a peanut. He succeeded   30   producing a kind of rice that could feed more people at home and abroad. His latest vision for “seawater rice” has also become a    31   (real), and potentially opened up nearly one million square kilometers of salty land in China for rice production.   32   his advanced years, Yuan Longping is still young at heart and full of vision, and everyone is waiting to see   33   he will dream up next.
