类文赏读　话题导入 A PIONEER FOR ALL PEOPLE Yuan Longping，known as the “father of hybrid rice”，is one of China’s most famous scientists.Yet，he considers himself a farmer because he continually works the land in his research.Indeed，his slim but strong body is just like that of millions of Chinese farmers，to whom he has devoted1 his life. Yuan Longping was born in 1930 in Beijing.His parents wanted him to pursue a career in science or medicine.However，what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage2 of food to eat.To tackle this crisis，he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing. After graduating in 1953，he worked as a researcher.Yuan Longping realised that larger fields were not the solution.Instead，farmers needed to boost yields in the fields they had.How this could be done was a challenging question at the time.Yuan was convinced3 that the answer could be found in the creation of hybrid rice.A hybrid is a cross between two or more varieties of a species.One characteristic of hybrids is that they usually attain a higher yield than conventional4 crops.However，whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate.The common assumption then was that it could not be done.Through intense effort，Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974.This hybrid enabled farmers to expand their output greatly. Today，it is estimated5 that about 60 percent of domestic rice consumption6 in China is comprised of crops generated7 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 innovation has helped feed not just China，but many other countries that depend on rice as well，such as India and Vietnam.Because of his invaluable contributions，Yuan Longping has received numerou
