Yuan Longping, "the father of hybrid rice(杂交水稻)", is one of the most important agricultural scientists. He spends his whole life on hybrid rice.
Food was a big problem in China in the past. It was because China had 22% of the world's population, but only 7% of its farmland. In the 1960s, China had serious hunger. Millions of people died because they had no food. Professor Yuan was very sad to see this. "How can I help people have enough food?" he thought. He decided to work on a new kind of hybrid rice that had a high output(产量). He and his team studied the rice seeds(种子)day and night. At last, in 1973, they grew a new kind of hybrid rice. 袁隆平很高兴因为他的想法实现了。This rice is strong. Farmers can grow it in many different kinds of farmland and also in bad weather. It can also fight diseases. Its output is much higher than common kinds of rice.
Professor Yuan has already left us, but he will be remembered forever.
It takes his whole life to study hybrid rice.
