17、s sunburnt face and arms and his slim，strong body are just like those of millions of Chinese farmers, for whom he has struggled for the past five decades. Yuan Longping grows what is called super hybrid rice. In 1973, he became the first agricultural pioneer in the world to grow rice that has a high
18、 output. This special strain of rice makes it possible to produce 20% more of the crop in the same fields. Now more than 60% of the rice produced in China each year is from this hybrid strain.Born in 1930, Yuan Longping graduated from Southwest Agricultural College in 1953. Since then, finding ways
19、to grow more rice has been his life goal. As a young man，he saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in many parts of the countryside. Yuan Longping searched for a way to increase rice harvests without expanding the area of the fields. In 1950,
20、 Chinese farmers could produce about fiftysix million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests mean that 22% of the worlds people are fed from just 7% of the farmland in the world. Yuan Longping is now circulating his
21、knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tools in the battle to rid the world of hunger. Using his hybrid rice, farmers are producing harvests twice as large as before.Yuan Longping is quite satisfied
22、 with his life. However, he doesnt care about being famous. He feels it gives him less freedom to do his research. He would much rather keep time for his hobbies.He enjoys listening to violin music, playing mahjong, swimming and reading. Spending money on himself or leading a comfortable life also m
23、eans very little to him. Indeed，he believes that a person with too much money has more rather than fewer troubles. He therefore gives millions of yuan to equip others for their research in agriculture.Just dreaming for things, however, costs nothing. Long ago Yuan Longping had a dream about rice pla
24、nts 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. He awoke from his dream with the hope of producing a kind of rice that could feed more people. Now, many years later, Yuan Longping has another dream：to export his rice so that it can
25、 be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people.译文参照造福全人类的先驱者尽管袁隆平是中国最有名的科学家之一，但他仍然认为自己是个农民，因为他在田间耕作，进行科学研究。的确，他晒黑的面庞和手臂，以及清瘦而又结实的身躯，就跟数百万中国农民一模一样，他过去50年来的努力工作就是为了帮助他们。袁隆平种植的是被称为“超级杂交水稻”的稻种。1973年，他成为世界上第一位种植高产水稻的农业先锋。这种特殊的稻种使得同样的
26、田地多收获20%的产量。如今中国每年出产的稻米有60%以上出自这种杂交稻种。袁隆平于1930年出生，1953年毕业于西南农学院。从那时起，找到水稻高产的方法便成为了他毕生的目标。年轻时，他就看到了水稻增产的巨大需求。那时，饥饿是许多农村地区面临的困扰。袁隆平开始在不增加土地面积的基础上寻求达到增收的途径。1950年，中国的农民只能生产大约5600万吨稻米，而近来却生产了将近两亿吨。这一粮食产量的增加意味着世界用仅仅7%的耕地养活了世界上22%的人口。目前袁隆平还在印度、越南和其他一些欠发达国家传播提高水稻产量的知识。由于他的研究，联合国在消除世界饥饿的战斗中有了更多的方法。用他的杂交水稻种子，
27、农民们种出的粮食比以前多了一倍。袁隆平很满意自己的生活。但他对成名并不关心。他觉得成名后搞研究就没那么自由了。他宁愿把时间花在自己的爱好上。他喜欢听小提琴演奏曲，玩麻将，游泳和看书。在自己身上花钱或享受舒适的生活对他而言意义不大。事实上，他认为一个人有了太多的钱，就会有更多而不是更少的烦恼。因此，他资助几百万元供其他人进行农业研究。做梦是不花本钱的。很久以前，袁隆平梦见水稻长得像高粱一样高，稻穗像玉米穗一样大，而每粒稻米都像花生一样饱满。他从梦中醒来，希望能种植一种能养活更多人的水稻。如今袁隆平还有另外一个梦想，那就是出口他的水稻，让它长遍全球。一个梦想总是不够的，尤其是对一个热爱和关心人民的

75、d their fields，which help prevent the loss of soil and stop the wind from blowing soil away.They also keep the wind from damaging or destroying crops.Besides，extra trees and plants can be cut down and used or sold for wood.Windbreaks can be highly valuable for protecting grain crops.For example，in p
76、arts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared to fields without them.But here is something interesting about windbreaks.They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field
77、.If not，then the movement of air close to the ground will lift the soil.Then the soil will be blown away.For this reason，a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line.An easy rule to remember is that windbreaks can prote
78、ct areas up to 10 times the height of the tallest trees in the windbreak.There should be at least two lines in each windbreak.One line should be large trees.The second line，right next to it，can be shorter trees or other plants with leaves.Locally grown trees and plants are considered the best choice
79、s for windbreaks.Trees reduce the damaging effects of wind and rain.Their roots help protect soil from being washed away.And trees can provide animals outdoors with shade from the sun.语篇解读：保护土壤的一个办法就是使用防风林，防风林是由树木和其他作物组成的障碍物。农民在农田周围种上这些障碍物，有利于增加农业收成。5The advantages of building a windbreak are as fol
