为所有人的先驱
袁隆平，被称为“杂交水稻之父”，是中国最著名的科学家之一。然而，他自认为是个农民，因为在研究中他不停地耕种土地。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。
because引导原因状语从句
to whom引导非限制性定语从句，修饰先行词Chinese farmers
Yuan Longping was born in 1930 in Beijing.His parents wanted him to pursue a career in science or medicine⑤.However, what concerned him most was that farmers often had poor harvests⑥ and sometimes even had a serious shortage of food⑦ to eat(3).To tackle this crisis⑧， he chose to study agriculture⑨ and received an education at Southwest Agricultural College in Chongqing.

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 (8).However, whether it was possible to develop a hybrid of self pollinating plants such as rice(9)was a matter of great debate .The common assumption then was that it could not be done(10).Through intense effort ， Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming(11)in 1974.This hybrid enabled farmers to expand their output greatly.
conventional crops 传统作物
a matter of great debate 一个有很大争议的问题
through intense effort 通过不懈的努力
overcome enormous technical difficulties 克服巨大的技术难题

杂交作物是一个物种的两个或两个以上变种的杂交。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，是否有可能培育出一种自花传粉的杂交植物，如水稻，这是一个有很大争议的问题。当时人们普遍认为这是不可能的。通过不懈的努力，袁隆平克服了巨大的技术难题，于1974年培育出了第一种可用于农业生产的杂交水稻。这种杂交水稻使农民大大增加了产量。
