[原文呈现]A PIONEER FOR ALL PEOPLEYuan Lngping, knwn as the “father f hybrid① rice”， is ne f China's mst famus scientists.Yet, he cnsiders himself a farmer because he cntinually wrks the land in his research. 1Indeed, his slim but strng bdy is just like that f millins f Chinese farmers, t whm he has devted② his life．Yuan Lngping was brn in 1930 in Beijing.His parents wanted him t pursue a career in science r medicine.Hwever, what cncerned him mst was that farmers ften had pr harvests and smetimes even had a serius shrtage③ f fd t eat.T tackle④ this crisis⑤， he chse t study agriculture and received an educatin at Suthwest Agricultural Cllege in Chngqing.
After graduating in 1953, he wrked as a researcher.Yuan Lngping realised that larger fields were nt the slutin.Instead, farmers needed t bst⑥ yields⑦ in the fields they had.Hw this culd be dne was a challenging questin at the time.Yuan was cnvinced⑧ that the answer culd be fund in the creatin f hybrid rice.A hybrid is a crss between tw r mre varieties f a species.One characteristic⑨ f hybrids is that they usually attain⑩ a higher yield than cnventinal⑪ crps.Hwever, whether it was pssible t develp a hybrid f self-pllinating⑫ plants such as rice was a matter f great debate.The cmmn assumptin⑬ then was that it culd nt be dne.Thrugh intense⑭ effrt, Yuan vercame⑮ enrmus technical difficulties t develp the first hybrid rice that culd be used fr farming in 1974.This hybrid enabled farmers t expand⑯ their utput⑰ greatly.
Tday, it is estimated⑱ that abut 60 percent f dmestic⑲ rice cnsumptin⑳ in China is cmprised㉑f crps generated㉒frm Yuan's hybrid strains㉓, and his strains have allwed China's farmers t prduce arund 200 millin tns f rice per year.Yuan's innvatin has helped feed nt just China, but many ther cuntries that depend n rice as well, such as India and Vietnam㉔.Because f his invaluable cntributins, Yuan Lngping has received numerus awards bth in China and abrad.Given that Yuan's hybrids have made him quite wealthy, ne might think he wuld retire t a life f leisure㉕.Hwever, this is far frm the case.Deep dwn㉖, Yuan is still very much a farmer at heart.As a man f the sil㉗, he cares little fr celebrity㉘r mney.Instead, he makes large dnatins t supprt agricultural research.
2What impresses peple mst abut Yuan Lngping is his nging ability t fulfil his dreams. Lng ag, he envisined㉙rice plants as tall as srghum㉚, with each ear f rice as big as a brm㉛, and each grain㉜f rice as huge as a peanut.He succeeded in prducing a kind f rice that culd feed mre peple at hme and abrad.His latest visin㉝fr “seawater rice” has als becme a reality㉞, and ptentially pened up nearly ne millin square kilmetres f salty㉟ land in China fr rice prductin.Despite his advanced years, Yuan Lngping is still yung at heart and full f visin, and everyne is waiting t see what he will dream up next.
[课文翻译]造福全人类的先驱者袁隆平，被誉为“杂交水稻之父”，是中国最著名的科学家之一。然而，他认为自己是个农民，因为他不断地在田间劳作，进行科学研究。1.确实，他瘦削但结实的身躯看起来和他为之奉献了一生的千百万中国农民一样。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，最让他担心的是，农民经常歉收，有时甚至严重缺乏食物。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，而是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。袁隆平坚信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常规作物高。然而，是否有可能培育出如水稻等自花授粉植物的杂交种，这是一个充满争议的问题。人们普遍认为这是不可能做到的。通过不懈的努力，袁隆平克服了巨大的技术难题，于1974年研制出了第一批可用于农业生产的杂交水稻。这种杂交植物使农民能够大幅度增加他们的水稻产量。
据估算，现在中国国内消费的稻米有大约60%来自袁隆平的杂交水稻品种培育的作物，这些品种(形成的作物)让中国农民每年能够生产出大约两亿吨稻米。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，如印度和越南。因为他做出了不可估量的贡献，袁隆平在国内外获得了无数奖项。考虑到杂交水稻使袁隆平变得相当富有，人们可能认为他会退休享受闲适的生活。然而，事实远非如此。实际上，袁隆平在内心深处仍然是一位农民。作为一个土生土长的人，他不太在乎名利。相反，他大量捐款支持农业科学研究。
2．袁隆平给人印象最深的是他不断实现梦想的能力。很久以前，他设想水稻高至高粱，稻穗大如扫帚，而每粒稻谷大如花生。他成功地种植出一种可以养活国内外更多人口的水稻。他对“海水稻”的最新设想也已成为现实，并可能在中国开辟近100万平方公里的盐碱地，用于水稻生产。尽管年事已高，袁隆平的内心仍然年轻并富有远见，每个人都在等着看他下一步的梦想。
