Eat out what you take.Father of Hybrid RiceA Pioneer For All People He is father of hybrid rice(杂交水稻), who was lately awarded “the Nobel Prize of Asia ”.He received the honor for his great contributions(贡献) to hybrid rice research and work he did to improve rice production in developing countries.Now he is head of the National Hybrid Rice Research and Development Center in Hunan Province, China (中国湖南省国家杂交水稻研究与发展中心).He is called a pioneer for all people. Dr Yuan Longping(袁隆平博士） 他是一位真正的耕耘者。当他还是一个乡村教师的时候，已经具有颠覆世界权威的胆识；当他名满天下的时候，却仍然只是专注于田畴。淡薄名利，一介农夫，播撒智慧，收获富足。他毕生的梦想，就是让所有人远离饥饿。喜看稻菽千重浪，最是风流袁隆平！
--- 袁隆平在2004感动中国中的颁奖词 他在接受“感动中国”栏目组采访时说：“这不是我个人的荣誉，而是国家的荣誉，全国人民的荣誉”。
袁隆平：“我感到最愉快的是一个出新成果，能够在名分上得到安慰的，有所寄托的要出新成果，我不停留在原有的这个成绩的基础上，我相信我们古人讲的话，“谋事在人，成事在天”。 有人曾经风趣地说，中国农民吃饭靠“两平”，一是靠邓小平的责任制，二是靠袁隆平的杂交水稻。
今天中国水稻种植面积中，约有一半是采用袁隆平培育的杂交产品，每年生产的稻谷可以多养活6000多万人。2004年，袁隆平领导的超级杂交稻项目不断取得重大突破，在育种方面提前一年实现了大面积亩产超过800公斤的目标，这意味着每年又可以多养活7500万人。Super Hybrid Ricethe rice that has a high output What kind of person is Dr Yuan

D. Yuan’s rice are grown in many countries Discussing Even if Dr.Yuan's dreams come true, can this really solve starvation?1. Dr Yuan wanted to increase the rice output because he saw many people go hungry when he was young.Suggested answers to Exercise 3 (P11)Post reading2. I think he is more of a scientist. His main purpose is not to make a profit for himself but to study agriculture and use that knowledge to improve farming for farmers everywhere. I do not think he is a businessman, because his goal is not to make money.3. Because of his work with developing hybrid rice, it seems that Dr Yuan must be a very patient and careful man. He didn’t give up but kept working on his project. He Also seems to be a very kind man, who cares for others. He wants to use his invention to help hungry people around the world.4. I think Dr Yuan was successful because he kept working and did not give up. He also grew up in a poor family, so he was very motivated to succeed and help other farmers around China. 5. I mostly agree. I think being rich can cause a lot of problems, but it really depends on the life and attitude of the person who is rich. People who are rich certainly have different problems from people who are not.6. I think developing other hybrid grains would make a great difference in the problem of world hunger. Hybrid grains that can survive in very dry or very hot areas would be very useful in Africa and other areas. Hybrid grains that cannot easily be killed by insects and diseases would be useful around the world.HomeworkWriting a poster(海报) for the text.Resume Name:
