给天使加上翅膀法
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.
Para 3
1953年大学毕业后，他成为一名科研人员。
而是农民们需要提高他们已有土地上农作物的产量。
如何实现这一目标成为当时一个颇具挑战性的问题。
袁隆平确信答案可以在杂交水稻的培育中找到。
杂交指的是两个或两个以上品种的交叉。
袁隆平意识到，解决问题的办法并不是扩大农田面积。
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.
Para 3
杂交作物的一个特点就是它们通常能获得比传统作物更高的产量。
然而，是否可能开发出水稻等自花授粉作物的杂交品种，仍众说纷坛。
当时普遍认为这是不可能实现的。
历经千辛万苦，袁隆平攻克了艰巨的技术难题，第一批可应用于农田(大规模)生产的水稻，于1974年开始耕种。
这种杂交水稻极大地提高了农民的产量。

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.

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.
Para 6
袁隆平给人们印象最深的是他不断实现梦想的能力。
很早以前，他就设想水稻长得与高粱一样高，每支稻穗与扫帚一样大，每粒稻谷与花生一样饱满。
袁隆平意识到，解决问题的办法并不是扩大农田面积。
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.
Para 6
后来他的“海水稻”愿景也成为了现实，并有望在中国开辟近100万平方公里的盐碱地用于水稻生产。
即使在他晚年，袁隆平仍然保持年轻的心态，而且满怀憧憬，
大家都会兴奋地期待他下一个不同寻常的想法。
Thank you!
