Born in[1]Beijing, Yuan Longping graduated from[2]Southwest Agricultural College in China in[3]1953, and since[4]his graduation he has devoted himself to[5]agriculturaleducation and research. His pioneering research has helped rid China of[6] hunger within[7] three decades. In 1973, in[8] cooperation with others, he was able to cultivate a type of hybrid rice species which had great advantages over[9] others and whose output would increase by[10] 20 percent than that of common ones. With[11] higher yields than previous varieties, Professor Yuan’s new crop，regarded as[12] the fifth invention after[13]China’s Four Major Inventions, has quickly improved China’s food supply. Without[14]any hesitation, he shared his knowledge and technology with foreign scientists, so farmers in more than ten other countries besides[15]China have thus benefited from[16]his work, gaining access to[17] his technology. In[18] return, he was awarded many international awards for his great achievements. In his spare time, Dr. Yuan loves playing the violin and listening to music. Every night，he reads for[19] half an hour about[20] various topics before he goes to sleep. But he cares for nothing more than his research and he goes to the fields twice a day by[21] motorbike, which has left a strong impression on[22] us.1.in地点介词，在某个城市、国家等范围较大的地点前用in；小地点，如station，airport，corner等前面常用at。
