Ⅱ. 阅读理解【主题：人与社会 杂交水稻之父】
Yuan Longping, one of the world’s greatest scientists, died at the age of 91 in Hunan in 2021. He was called the “Father of Hybrid Rice (杂交水稻)” and helped feed people around the world.
Yuan Longping was the first person to develop a kind of hybrid rice which helped fight hunger in China. Food was a big problem in China in the past. This was because China had 22 percent of the world’s population, but only 7 percent of its farmland. In the 1960s, Chinese people had a difficult time, because millions of people suffered from hunger. As an agronomy (农学) teacher, Yuan was very sad to see this. “How can I help them have enough food?” he thought. He decided to work on a kind of hybrid rice. It has a high output.
At that time, other scientists didn’t think hybrid rice was worth studying. But Yuan and his team worked on it every day. They took very good care of their rice seeds.
At last, in 1973, they grew a new kind of hybrid rice. This rice is strong. Farmers can grow it in many different kinds of farmland and in bad weather. It can also fight disease. Its output is much greater than common kinds of rice. With the new kind, about 70,000,000 people could have food every year!
Yuan solved the food problem in China. But he was still working on rice when he was very old. Before he retired, he hoped to grow rice in the sea!
Yuan once said he had two dreams—to “enjoy the cool under the rice crops (庄稼) taller than man” and to grow hybrid rice all over the world to help solve the global (全球的) food problem.
