Yet,he considered himself a farmer because he continually worked the land<m></m> in his research. Indeed,his slim<m></m> but strong body was just like that of millions of Chinese farmers, <m></m><uw>to whom he had devoted<m></m> his life</uw>. ［1］此处是过去分词短语作定语，修饰Yuan Longping。“be known as...”意为“以……著称；被称为”。 11 ［2］此处是“介词+关系代词”引导的定语从句，修饰先行词farmers。“devote...to”是固定搭配，此处介词to被提到了关系代词前面。 Yuan Longping was born in 1930 in Beijing. His parents wanted him to pursue a career<m></m> in science or medicine. However, what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage<m></m> of food to eat. <m></m><uw>To tackle<m></m> this crisis<m></m></uw>, he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing. 12 ［3］此处是动词不定式短语作目的状语。 After graduating in 1953, he worked as<m></m> a researcher. Yuan Longping realised that larger fields were not the solution<m></m>.Instead,farmers needed to boost<m></m> yield<m></m> in the fields <m></m><uw>they had</uw>.<m></m><uw>How this could be done</uw> was a challenging question at the time. Yuan was convinced<m></m> that the answer could be found in the creation of hybrid rice. 13 A hybrid is a cross<m></m> between two or more varieties of a species<m></m>. One characteristic<m></m> of hybrids is <m></m><uw>that they usually attain<m></m> a higher yield than conventional<m></m> crops</uw>.However, <m></m><uw>whether it was possible to develop a hybrid of self-pollinating<m></m> plants such as rice</uw> was a matter of great debate. The common assumption<m></m> then was that it could not be done. <m></m><uw>Through intense<m></m> effort</uw>,Yuan overcame<m></m> enormous<m></m> technical difficulties to develop the first hybrid rice<m></m><uw>that could be used for farming in 1974</uw>. This hybrid enabled<m></m> farmers to expand<m></m> their output<m></m> greatly. ［4］此处是定语从句，修饰先行词the fields。当引导词that/which在从句中作宾语时，可以省略。 ［5］此处是主语从句，引导词是how，整个从句一起作主语。 ［6］此处是表语从句，引导词that在从句中不作任何成分，只起连接作用，不可省略。 ［7］此处是由whether引导的主语从句。 16 ［8］此处是介词短语作状语。 ［9］此处是定语从句，修饰先行词the first hybrid rice。 Today, it is estimated<m></m> that about 60 percent of domestic<m></m> rice consumption<m></m> in China is comprised of <m></m> crops generated<m></m> from Yuan's hybrid strains<m></m> , and his strains have allowed China's farmers to produce around 200 million tons of rice per year. Yuan's innovation<m></m> has helped feed not just China, but many other 17 countries<m></m><uw>that depend on rice as well, such as India and Vietnam</uw>.Because of his invaluable<m></m> contributions,Yuan Longping received numerous<m></m> awards both in China and abroad. ［10］此处是定语从句，先行词是countries，that在定语从句中作主语，此处that也可换成which。 Given that Yuan's hybrids made him quite wealthy, one might think he would have retired to a life of leisure<m></m> .However, this is far from the case<m></m> .Deep down<m></m> ,Yuan was still very much a farmer at heart. As a man of the soil<m></m> ,he cared little for<m></m> celebrity<m></m> or money. Instead, he made large donations to support<m></m> agricultural research. 19 <m></m><uw>What impressed people most about Yuan Longping</uw> was his ongoing<m></m> ability to fulfil his dreams<m></m> .Long ago, he envisioned<m></m> rice plants as tall as sorghum<m></m>, with each ear<m></m> of rice as big as a broom<m></m> , and each grain<m></m> of rice as huge as a peanut. He succeeded in producing<m></m> a kind of rice<m></m><uw>that could feed more people at home and abroad</uw>.His later vision<m></m> for 20 “seawater rice” also became a reality<m></m>,and potentially<m></m> opened up<m></m> nearly one million square kilometres of salty<m></m>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<m></m> next. ［11］此处是主语从句。what是主语从句的引导词，在主语从句中作主语。 ［12］此处是定语从句，先行词是a kind of rice，that在定语从句中作主语。 22 全民先锋 袁隆平被誉为“杂交水稻之父”，是中国最著名的科学家之一。然而，他认为自己是一个农民，因为他一直在田间从事他的研究工作。确实，他瘦削但结实的身躯看起来和他为之奉献了一生的千千万万的中国农民一样。 袁隆平1930年出生于北京。他的父母希望他从事科学或医学方面的工作。然而，最让他忧心的是，农民经常歉收，有时甚至严重缺粮。 23 为了应对这一危机，他选择了学习农业，并在重庆的西南农学院接受教育。 1953年毕业后，他从事了研究工作。袁隆平意识到，解决问题的办法并不是扩大农田面积。相反，农民们需要提高他们已有土地上农作物的产量。如何做到这一点在当时是一个具有挑战性的问题。袁隆平确信他可以在杂交水稻的培育中找到答案。杂交植物是一个物种的两个或多个变种之间的杂交。杂交作物的一个特点是它们的产量通常比传统作物高。然而，是否有可能培育出水稻等自花授粉植物的杂交 种，是一个有很大争议的问题。当时的普遍假设是这是做不到的。通过不懈的努力，袁隆平克服了巨大的技术困难，于1974年培育出了第一批可用于农业生产的杂交水稻。这种杂交作物使农民能够大幅度地增加他们的水稻产量。 据估计，现在中国国内消耗的约60％的大米是由袁隆平的杂交水稻品种生产的水稻组成的，他的杂交水稻品种让中国农民每年能够生产出大约2亿吨大米。袁隆平的创新不仅帮助养活了中国，也养活了许多其他依赖大米的国家，比如印度和越南。因为他做出的不可估量的贡献，袁隆平在国内外获得了无数奖项。 考虑到袁隆平的杂交水稻使他变得相当富有，人们可能认为他已经退休，享受闲适的生活。然而，事实远非如此。袁隆平在内心深处依然是一个农民。作为一个土生土长的人，他不太在乎名声和金钱。相反，他大量捐款支持农业研究。 最让人印象深刻的是袁隆平不断实现梦想的能力。很久以前，他设想水稻像高粱一样高，每一个谷穗都像扫帚一样大，每一粒米都像花生一样大。他成功地培育出一种可以养活国内外更多人口的大米。他后续培育“海水稻”的设想也成为现实，并可能在中国开辟近100万平方千米的盐碱地，用于水稻生产。甚至在他的晚年，袁隆平的内心仍然年轻，满怀憧憬，每个人对他下一步的设想都激动不已。 $
