問問題的學生
    在當前的世界，水稻是主要糧食。中國是世界上最大的水稻產地。亞洲其他國家和一些歐洲國家比如意大利等，都種植水稻。在水稻種植界，中國科學家袁隆平是一位重要人士。
    袁隆平生長在中國。小時侯，他在學校讀過書，得了個“問問題的學生”的綽號。袁隆平從小就對植物感興趣。他在大學里研究農學。作為一個年輕的教師，他開始了作物育種的實驗。他想，養活世人的關鍵是更快更好的生產水稻。他認為，唯一的辦法是使不同種類的水稻雜交，這樣就能產生比原先任何一種水稻產量都要高的新品種。
   首先，袁隆平對不同種類的水稻進行實驗。1996年，他的研究成果在中國發表。接著他開始尋找一種特殊的稻種。這種稻種必須是雄性的，必須是不結果的。最后，在1970年，一種天然的雄性不育稻種被發現，這是一個突破性的發現。全國各地的研究者們被召集在一起開發新水稻種。研究得到了政府的贊助。
