Look at my sunburnt face and arms and my slim, strong body and you will think I’m more like a farmer than a scientist. In fact I have struggled for the past five decades to help farmers. In 1974, I began to grow a so-called super hybrid rice. This special strain of rice makes it possible to produce one-third more of the crop in the same fields. I was born into a poor farmer’s family in 1931. When I was young, I saw many people go hungry often. So I have devoted myself to finding ways to increasing rice harvest without expanding the area of fields since I graduated from Southwest Agriculture College in 1953. Now more than 60 % of the rice produced in China each year is from this hybrid strain.,I am circulating this knowledge in India, Vietnam and other less developed countries to increase their harvest. Perhaps you think I am rich. Actually I live a simple life. I care little for money. In my opinion a person with too much money will have more troubles.,I don’t want to be famous because I prefer to have more time to do my research. In my free time I love listening to music, playing mah-jong and reading. I once had a dream, in which I saw rice plants as tall as sorghum and each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Now I have another dream—to export my rice so that it can be grown all over the world.,Language points,1) 辨析because, for because表示理由充分,有必然因果關(guān)系, 能回答以why引起的問句。,1.
