Unit 5 Working the Land A PIONEER FOR ALL PEOPLE Period 2 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 devoted his life. n. 先驱 v. 开创 be known as/for 确实 adv. Para. 1 His slim but strong body is just like that of millions of Chinese farmers, to whom he has devoted his life. 此句为 “介词+关系代词”引导的______从句，先行词为__________________________, devote...to...为固定搭配 Eg. 1.The school in_________my brother once studied is very famous. 2.My mother missed her best friend with______she worked in her youth. 小结: “介词+关系代词” 既可以引导限制性定语从句，也可以引导非限。 先行词为人时，用whom；先行词为物时，用which。 定语 millions of Chinese farmers which whom 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. choose--chose--chosen choice n. 选择 从事 主语从句+表语从句 Para. 2 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 (that/which) 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. solve Para. 3 One characteristic of hybrids is that they usually attain a higher yield than conventional 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., 传统农作物 争论 Para. 3 普遍的假设 克服了巨大的技术难题 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 has received numerous awards both in China and abroad. 品种 无价的贡献 Para. 4 Given 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 the 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 donations to support agricultural research. 鉴于；考虑到 原因状语从句 退休 情况远非如此 Para. 5 What impresses people most about Yuan Longping is his ongoing ability to fulfill 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. 不断的 设想 Para. 6 His latest vision for “seawater rice” has also become a reality, and potentially opened up nearly one million square kilometres of salty land in China for rice production. Despite his advanced years, Yuan Longping is still young at heart and full of vision, and everyone is waiting to see what he will dream up next. 最新的设想 可能地 高龄 开辟 尽管 Para. 6 general impression life experiences achievements in agriculture attitudes towards life dreams  known as ________________________  one of China's most famous ____________  ______ but ______ body  was born in ________ in Beijing  graduated from ________________________________  worked as a ____________ in 1953  developed the first __________ in 1974  provided about ___________ of domestic rice consumption and allowed China's farmers to produce around ___________ _______ of rice per year  helped feed many other countries, such as _____  received numerous ________ both in China and abroad  He is still very much a _________ at heart.  He cares little for _________ or ________.  Long ago: rice plants as tall as ________; each ear of rice as big as a _______; each grain of rice as huge as a_________  Latest vision: __________________(has become a reality) “father of hybrid rice” scientists slim strong 1930 Southwest Agricultural College researcher hybrid rice 60 percent 200 million India and Vietnam awards farmer celebrity money sorghum broom peanut “seawater rice” tons Thanks! 12 $$
