Module 4 Great ScientistsWhich are you interested in, botany, biology, biochemistry, zoology, genetics or cosmology? There are brilliant scientists in every field. Today, I'll introduce one of them to you.Dr Yuan Longping is a leading figure in China's agricultural research. Dr Yuan is known for his super hybrid rice and has been awarded several times. Born, brought up and educated in China, Dr Yuan knew that many people suffered from hunger. A lot of them even earn their living by begging. At that time rice was a staple food in China. So he dreamed of developing a new species to raise rice production to feed more people. After graduating, supported by the government, he devoted himself to the research. As a result of his years' efforts, in 1970, he made a great breakthrough and finally developed hybrid. This hybrid rice has a higher yield than either of the original plants. His discovery was published in newspapers worldwide. Now, Dr Yuan's rice has gradually replaced the common rice and much of the land has been converted to growing vegetables and cash crops. Large quantities of rice have been exported to other countries, which partly solve the world hunger.Dr Yuan's personal life is very simple. Sometimes, he escapes his busy life by playing the violin or mahjongg. Though he is in his eighties, his physical condition is very good. For his career, he once made a brief summary: I'm only a student who asks questions.你对什么感兴趣，是植物学、生物学、生物化学、动物学、遗传学还是宇宙生成学呢？在每一个领域里都有才华横溢的科学家。今天我给你们介绍其中的一位。袁隆平博士在中国农业研究中是一位重要人物。他因自己的超级杂交水稻而出名，而且多次获奖。袁隆平在中国出生、长大并接受教育，他知道很多人遭受着饥饿。他们当中很多人甚至通过乞讨谋生。那时，水稻是中国的主要粮食。于是他就梦想培育一个新的品种提高水稻的产量，以养活更多的人。大学毕业后，在政府的支持下，袁博士便投身于该项研究中。由于他多年努力的结果，1970 年他取得了重大的突破，最终培育出了杂交品种。这种杂交水稻的产量比原来的品种要高。他的发现在全世界的报纸上公布。现在，袁博士的水稻已经逐渐地取代了原来的普通水稻，而且许多土地都被转换来种蔬菜和经济作物。大量的水稻已经出口到其他国家，这在一定程度上解决了世界饥饿问题。袁博士的个人生活很简单。有时，他会通过拉小提琴或打麻将来暂时逃避自己繁忙的工作。尽管已经八十多岁了，他的身体状况依旧很好。对于自己的事业，他曾经做了一个简短的总结：我只是一个爱问问题的学生。
