Dr Yuan Longping grows what is called super hybrid rice. In 1974, he became the first agricultural pioneer （）in the world to grow rice that has a high output. This s 3 strain of rice makes it possible to produce one-third more of the crop in the same fields. Now more than ( )60% of the rice p 4 in China each year is from this hybrid strain.Born( ) in 1930, Dr Yuan g 5 from Southwest Agricultural College in 1953.

He t 12 gives millions of yuan to equip others for their research in a 13 .Just dreaming for things, however, costs nothing. Long ago Dr yuan had a dream about（）rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Dr Yuan awoke from （)his dream with the hope of producing a kind of rice that could fee more people. Now, many years later, Dr Yuan has another dream: to e 14 rice so that it can be grown around the g 15 . One dream is not always enough, especially( ) for a person who loves and cares for his people.1 2 3 4 56 7 8 9 1011 12 13 14 15二语法知识要点：对照课文看看怎样用的，想一想为什么这样使用？1 (born )in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953. 解析born 这里是过去分词作时间状语，它与句子主语逻辑上形成了。
