參考譯文:
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(yǎng)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(fā)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(fā)現(xiàn),這是一個突破性的發(fā)現(xiàn)。全國各地的研究者們被召集在一起開發(fā)新水稻種。研究得到了政府的贊助。
由于袁隆平的發(fā)現(xiàn),中國的水稻產量在20世紀90年代增長了47.5%。還有其他的益處,五萬平方公里原來的稻田現(xiàn)在被用來種植蔬菜和其他經濟作物。除此之外,袁隆平研制的水稻還出口到巴基斯坦和菲律賓等國家。
在巴基斯坦,水稻是繼小麥之后的第二種最重要的作物并將在許多地方種植。中國袁隆平高科技公司以開發(fā)出一種新的雜交水稻。這種雜交水稻的產量遠高于巴基斯坦其他種類的水稻。
