12、His parents wanted him to pursue a career in science or medicine. He chose to study agriculture. What concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage of food to eat. And he wanted to tackle this crisis. After graduating in 1953, he worked as a re

13、searcher. 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 c

14、ross 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

15、 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. How did Yuan develop hybrid rice? 1.Drive / Motivation:_ 2.Characteri
