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. 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. 1. 增加产量 2. 深信，确信 3. ...的一个特征 4. 获得更高的产量 5. 一个极具争议的问题 6.通过不懈的努力 7.克服巨大的困难 8.使某人能做某事 Para 3 After graduating in 1953, he worked as a researcher.

Para 6 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. 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. Even in his later years, Yuan Longping was still young at heart and full of vision, and everyone is waiting to see what he will dream up next. 1. 实现某人梦想 2. 在某方面成功 3. 开辟，开发 4. 富有远见 5. 构思,创造 Para 6 What impresses people most about Yuan Longping is his ongoing ability to fulfill his dreams.
