hybrid”,is one of Chinas most famous scientists.Yet,he considers himself a farmer because he continually works the land in his research.Indeed,his slim but strong body is just like that of millions of Chinese farmers,to whom he has devoted his life.para.1be known as 被称为被称为be devoted

about Yuan Longping as a“pioneer for all people”directly and indirectly?Because he continually works the land in his research.Possible answers:1.Yuan is known as“father of hybrid rice”.Father means the first person to do something,or a pioneer.2.His method of doing the pioneering work is mainly field research.3.Yuan has devoted all his life to pioneering agricultural research.Reading Yuan Longping was born in 1930 in Beijing.His parents wanted him to pursue a career in science or medicine.However,what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage of food to eat.To tackle this crisis,he chose to study agriculture and received an education at Southwest Agricultural College in

that farmers often had poor harvests and sometimes even had a serious shortage of food to eat.To tackle this crisis,he chose to study agriculture.Reading 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在在19531953年毕业之后年毕业之后从事研究工作从事研究工作提高产量提高产量一个具有挑战性的问题一个具有挑战性的问题杂交水稻的培育杂交水稻的培育引导宾语从句引导宾语从句是省略了关系代词是省略了关系代词thatthat的定语从句的定语从句引导主语从句引导主语从句引导宾语从句引导宾语从句ReadingOne 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传统作。
