造福人类的先驱者
尽管是中国最著名的科学家之一,袁隆平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,他那被太阳晒得黝黑的脸庞和手臂,以及他那瘦削而又结实的身躯,就跟其他千百万中国农民一样,过去50年来,他一直在努力帮助他们。袁隆平博士种植的是被称为“超级杂交水稻”的稻种。1974年,他成为世界上第一位种植高产水稻的农业先驱。这种特殊的稻种使得同样的田地多收获三分之一的产量成为可能。如今中国每年出产的稻米有60%以上出自这种杂交稻种。
袁博士于1930年出生在一个贫穷的农民家庭,1953年毕业于西南农学院。从那时起,找到种植更多水稻的方法就成为他一生的目标。年轻时,他就看到了稻田增产的巨大需求。当时,饥荒是许多农村地区面临的一个令人不安的问题。袁博士要在不增加土地面积的基础上寻求达到增收稻米的途径。1950年,中国农民只能生产五千万吨稻米,而近来却生产了将近两亿吨稻米。这一粮食产量的增加意味着中国用仅仅占世界7%的耕地养活了世界22%的人口。袁博士现在在印度、越南和很多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。
袁博士对生活非常满足。但是,他对成名并不关心,并且觉得出名后搞科研就不那么自由了。他宁愿把时间花在自己的业余爱好上。他喜欢听小提琴乐曲、打麻将、游泳和读书。在自己身上花钱或者享受舒适的生活对袁博士来说意义也不大。事实上,他认为一个人有了太多钱,他的麻烦事只会更多,而不是更少。于是,他拿出好几百万元帮助其他人进行农业科学研究。
然而,梦想是不花本钱的。很久以前,袁博士曾在梦里看到水稻长得像高粱一样高,稻穗跟玉米穗一样大,而每粒稻米像花生米一般大。袁博士从梦中醒来,希望能种植一种能养活更多人的水稻。许多年后的今天,袁博士还有另外一个梦想:他的稻谷可以出口并长遍全
球。一个梦想并不足够,尤其对一个热爱和关心人民的人来说更是如此。
