Of the three great person, I would like to choose Yuan Longping, an agricultural pioneer of China. It is known that there exists hunger in many countries. To help more people to get enough food, Yuan Longping has devoted himself to improving the output of hybrid rice. Thanks to his research, the output has been doubled. More importantly,

Yuan Longping is willing to share his achievement with others, which contributes to ridding the world of hunger.

As for me, Yuan Longping is the greatest person in the world. It is his devotion that makes him successful and his devotion has inspired me a lot. Actually, I have some difficulty in learning English. However, where there is devotion, there is a way. I really believe that my devotion can make me expert in English.
