(Identities) Yuan Longping, known as the “father of hybrid rice”, was one of China’s most famous scientists. Yet, he considered himself a farmer because he continually worked the land in his research. Indeed, his slim but strong body was just like that of millions of Chinese farmers, to whom he had devoted his life. 袁隆平，被誉为 “杂交水稻之父”，是中国最著名的科学家之一。但他始终认为自己只是一名农民，因为在研究工作中，他常年扎根田间。他身形瘦削却体格强健，和千千万万中国农民别无二致，他将毕生都奉献给了这片土地与农民。 1. Why did Yuan Longping consider himself a farmer? Because he continually worked the land in his research. 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 shortage of food to eat. To tackle this crisis, he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing. 袁隆平 1930 年生于北京。父母希望他日后从事科学或医学相关工作。但最让他忧心的是，农民常常收成惨淡，有时甚至严重缺粮。为解决这一难题，他选择攻读农学，就读于重庆西南农学院。 D. Yuan decided to study agriculture. (Education) 2. Why did Yuan decide to study agriculture? He was concerned that farmers had poor harvests and sometimes even had a shortage of food to eat. 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 convinced 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 conventional crops. 1953 年毕业后，他成为一名科研人员。袁隆平意识到，扩大耕地面积并非解决粮食问题的办法。相反，农民需要在现有土地上提高产量。在当时，如何实现这一目标是一道难题。袁隆平坚信，答案就在于培育杂交水稻。杂交品种是同一物种两个或多个品种杂交培育出的产物。杂交作物的一大特点是，产量通常高于传统农作物。 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. 然而，水稻这类自花授粉作物能否培育出杂交品种，在当时引发了巨大争议。那时人们普遍认为这根本无法实现。经过不懈的艰苦钻研，袁隆平攻克了重重巨大技术难关，在 1974 年成功培育出首个可投入农田种植的杂交水稻。这种杂交水稻大幅提升了农民的粮食产量。 A. Yuan conducted research and developed hybrid rice. (Research & Achievements) 3. What is the main advantage of hybrid crops? One characteristic of hybrids is that they usually attain a higher yield than conventional crops. How did Yuan Longping develop hybrid rice in paragraph 3. as a researcher in 1953 worked realised larger fields boost yields was convinced the creation of hybrid rice overcame enormous technical difficulties developed the first hybrid rice in 1974 Today, it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated 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 received numerous awards both in China and abroad. 据估算，如今中国国内消费的大米中，约 60% 都产自袁隆平培育的杂交水稻品种。依靠这些稻种，中国农民每年能够产出约 2 亿吨水稻。袁隆平的创新成果不仅养活了中国人民，也惠及印度、越南等诸多以水稻为主食的国家。凭借他不可估量的贡献，袁隆平在国内外斩获无数奖项。 E. Yuan’s innovation has helped to feed more people. (Contributions & Influence) Today, it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated 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 received numerous awards both in China and abroad. E. Yuan’s innovation has helped to feed more people. (Contributions & Influence) Yuan’s innovation has helped feed not just China, but many other countries that depend on rice as well, such as India and Vietnam. 4. How has Yuan’s work helped China and other countries? Given that Yuan’s hybrids made him quite wealthy, one might think he would have retired to a life of leisure. However, this is far from the case. Deep down, Yuan was still very much a farmer at heart. As a man of the soil, he cared little for celebrity or money. Instead, he made large donations to support agricultural research. 既然袁隆平培育的杂交水稻让他拥有不菲财富，人们或许会以为他早已退休，过上悠闲安逸的生活。然而事实远非如此。在内心深处，袁隆平自始至终都是一名农民。一生扎根土地的他，对名利财富毫不在意。相反，他多次大额捐款，用以支持农业科研事业。 F. Yuan cared little for fame or wealth. (Qualities) What impressed people most about Yuan Longping was his ongoing ability to fulfil his dreams. Long ago, he envisioned rice plants as tall as sorghum, with each ear of rice as big as a broom, and each grain of rice as huge as a peanut. He succeeded in producing a kind of rice that could feed more people at home and abroad. His later vision for “seawater rice” also became a reality, and potentially opened up nearly one million square kilometres of salty land in China for rice production. Even in his later years, Yuan Longping was still young at heart and full of vision, and everyone was always excited to see what he would dream up next. 袁隆平最打动世人的，是他始终拥有实现梦想的能力。很久以前，他就畅想过水稻能长得像高粱一般高，稻穗如同扫帚那般硕大，谷粒像花生一样饱满。他成功培育出一种水稻，惠及国内外众多百姓。他后来设想的 “海水稻” 也成为现实，有望让中国近一百万平方千米的盐碱地得以种植水稻。即便到了晚年，袁隆平内心依旧年轻、满怀理想，所有人都满怀期待，想知道他接下来又会萌生怎样的奇妙构想。 B.
