Chongqing.(3)what concerned him most为主语从句that farmers...为表语从句其中不定式短语to eat作名词food的后置定语。After graduating in 1953 he worked as a researcher.Yuan Longping realised that larger fields were not the solution(4).Instead, farmers needed to boost yields in the fields they had(5).How this could be done(6)was a challenging question at the time.Yuan was convinced that the answer could be found in the creation of hybrid rice(7).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 self­pollinating 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

succeeded in producing a kind of rice that could feed more people at home and abroad(16).His latest vision for seawater rice has also become a reality and potentially opened up nearly one million
