6、 hungry world rice is a staple food and China is the worlds largest producer.Rice is also grown in many other Asian countries，and in some European countries like Italy.In the rice-growing world,the Chinese scientist,Yuan Longping，is a leading figure.Yuan Longping was born and brought up in China.As
7、a boyhe was educated in many schools and was given the nickname，“the student who asks questions”From an early age he was interested in plants.He studied agriculture in college and as a young teacher he began experiments in crop breeding.He thought that the key to feeding people was to have more rice
8、 and to produce it more quickly.He thought there was only one way to do thisby crossing different species of rice plant,and then he could produce a new plant which could give a higher yield than either of the original plants.First Yuan Longping experimented with different types of rice.The results o
9、f his experiments were published in China in 1966.Then he began his search for a special type of rice plant.It had to be male.It had to be sterile.Finally,in 1970 a naturally sterile male rice plant was discovered.This was the breakthrough.Researchers were brought in from all over China to develop t
10、he new system.The research was supported by the government.As a result ofYuan Longpings discoveries Chinese rice production rose by 47.5 percent in the 1990s.There were other advantages too.50 thousand square kilometres of rice fields were converted to growing vegetables and other cash crops.Followi
11、ng this，Yuan Longpings rice was exported to other countries,such as Pakistan and the Philippines.In Pakistan rice is the second most important crop after wheat and will be grown in many parts of the country.The new hybrid rice has been developed by the Yuan Longping High-tech Agricultural Company of

16、问题的学生”的绰号。袁隆平从小就对植物感兴趣。他在大学里研究农学，作为一名年轻的教师，他开始了作物育种方面的实验。他认为，解决人们吃饭问题的关键在于拥有更多的大米，并且能更快地生产出来。他认为，唯一的办法是使不同品种的水稻杂交，这样就能培育出比原先任何一种水稻产量都要高的新品种。首先，袁隆平对不同品种的水稻进行了实验。1966 年，他的实验结果在中国发表了。接着，他开始寻找一种特殊的稻种。这种稻种必须是雄性且不结果的。终于在 1970 年，一种天然的雄性不育稻种被发现。这是一个突破。中国各地的研究者们被召集在一起开发新的水稻品种。这项研究由政府支持。由于袁隆平的发现，中国的水稻产量在 20 世
17、纪 90 年代增长了 47.5%。这一发现还带来了其他的好处。5 万平方千米的稻田被改为种植蔬菜和其他经济作物。在这之后，袁隆平研制的水稻还出口到巴基斯坦和菲律宾等其他国家。在巴基斯坦，水稻是继小麦之后第二重要的作物并将在这个国家的许多地方种植。中国袁隆平高科技农业公司已培育出新的杂交水稻。这种杂交水稻的产量远高于巴基斯坦其他种类水稻的产量。通语篇 学理解 重分析2 语篇理解.Read the text and match the main idea of the paragraphs.1Para.1AHis discoveries have brought in great profit.2
