Firstly,     1    (最让我感动的是) Yuan Longping’s determination to tackle the crisis of the serious shortage of food and his dream to feed more people in the world. Not only should we care about ourselves, but also we should care about others.

Secondly,     2     (使他成为伟大的农学家的是他克服各种困难的不懈努力). As a student,    3     (我认为我们应该努力学习是重要的) and never give up when facing difficulties.

Last but not least,     4     (我们能否成功取决于) whether we devote ourselves to our work.

Yuan Longping, known as the “father of hybridrice”, is one of China’s 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 miliions of Chinese farmers, to whom he has     1     his life.

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 somnetimes even had a serious    2     of food to eat. To tackle this     3     , he chose to study agriculture and received aneducationat Seuthwest Agricultural College in Chomgqing.

How this could be done was a challenging question at the time.Yuan was     6    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    7    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     8    then was that it could not be done.
