【解析】

试题分析：本文介绍“水稻之父”袁隆平的巨大贡献。

【1】what 句意：袁隆平培植出了被称作超级杂交稻的水稻。grows后跟宾语从句，从句缺少引导词和主语，根据句意是指物，填what。

【2】to produce it是形式宾语，动词不定式作真正的宾语，故填to produce。

【3】has been 根据Since then可知，此处用现在完成时态，故填has been。

【4】disturbing 现在分词作前置定语，意为“令人烦恼的”，故填disturbing。

【5】without 句意：袁在寻找一种方法在没有扩大种植面积的同时增加水稻产量。此处填without。

【6】however 句意：然而，最近的一次产量差不多有两亿吨水稻被生产出来。和以前的“56 million tons”相比较，形容现在的产量高，故此处表示转折，又因为此处有逗号，故填however。

【7】increased 产量是被增长，故此处是过去分词作前置定语，故填increased。

【8】are fed 人是被喂养，故此处people和feed之间是被动关系，再根据句意可知，用一般现在时态的被动语态，故填are fed。

【9】countries many修饰可数名词的复数形式，故填countries。

【10】Using 动词与主语farmers是主动关系，故用现在分词作条件状语，故填Using。

【知识拓展】

和现在完成时态常连用的时间状语有：lately，since then，so far，in the last/past few years， since（自从……以来），for +一段时间……等。
