Unit 1 Science and Scientists 单元话题阅读理解练习 （2022春·宁夏银川·高二校考学业考试）Although he is one of China’s most famous scientists, Yuan Longping considers himself a farmer, for he works the land to do his research. Indeed, his sunburnt face and arms and his slim, strong body are just like those of millions of Chinese farmers, for whom he has struggled for the past five decades. Yuan Longping grows super hybrid rice. In 1973, he became the first agricultural pioneer in the world to grow the super hybrid rice that has a high output. This special strain of rice makes it possible to produce 20% more of the crop in the same fields. Now more than 60% of the rice is from this hybrid strain. Born in 1930, Yuan Longping graduated from Southwest Agricultural College in 1953. Since then, finding ways to produce more rice has been his life goal.
