A scientist in China had a dream when he was a child.In his dream，he grew a new kind of rice that was as big as a peanut.The plant allowed farmers to rest in its shade（阴凉处）.The child was Yuan Longping.Many years later，he grew up and became the "Father of Hybrid Rice"
   In the 1960s，a few years after he fnished his studies in agriculture（农业） at university，he came up with an idea for hybrid rice（杂交水稻）.Since then，he has spent much of his time researching and developing new kinds.
   In 1973，together with other scientists，he succeeded in developing hybrid rice.The introduction of this new product made China a leader in rice production.For this，he became known as the " Father of Hybrid Rice".In 1980，the technology for hybrid rice was introduced to the United States，and later，to the other parts of the world.
   Dr.Yuan's success with hybrid rice has helped farmers produce much more rice than before.Now Dr.Yuan is working on developing super hybrid rice.Yuan is busy working all day，but he still has lots of hobbies.In his spare time，Dr.Yuan loves playing the violin and listening to music.Every night，he reads for half an hour before he goes to sleep.He likes swimming，too.
