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，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人来说，更是如此。①HelenKellerbecamedeafandblindwhenshewas19m

ean?A．Possibletoimagine.B．Impossibletochange.C．Impossibletounderstand.D．Possibletounderstand.[解析]词义猜测题。根据第二段可知，每年浪费的食物的重量超过了860万头地球上最大的动物——蓝鲸

的重量，也超过了230万架世界上现有的最大的飞机——空中客车A380的重量。这也好比在世界拥有超过13亿人的人口最多的国家——中国，人均向垃圾桶里倾倒一吨的食物。由此可推知这种现象使人难以理解。unfathomable意为“难以理解的；深不可测的”。[答
