【回答】

篇章导读：本文是一篇说明文。文章讲述了*为保护环境对农作物的种植做了一些调整。

1．has grown　考查动词的时态。since后接时间点，句子要用现在完成时。句意：2011年以来，*种植的玉米比水稻多。故填has grown。

2．the　考查冠词。句意：玉米产量在过去25年里增长了近125%，而大米只增长了7%。此处特指在过去的25年里。故填the。

3．actually　考查词*转换。句意：对肉的喜爱实际上是这种变化背后的原因。此处用副词修饰be动词is。故填actually。

4．to improve　考查非谓语动词。句意：为了改善水质，*鼓励农民种植玉米，而不是水稻。此处用不定式表示目的。故填to improve。

5．than　考查连词。句意：玉米比水稻使用的水更少。根据关键词less可知，应填用于两个事物进行比较的连词。故填than。

6．pollution　考查词*转换。句意：这一转变减少了*主要的湖泊和水库的污染，使人们的饮用水更加安全。has decreased后跟名词作宾语，故填pollution。

7．global　考查词*转换。句意：*约占全球化肥总消费量的30%。fertilizer consumption是名词短语，应该用形容词修饰。故填global。

8．started　考查动词的时态。句意：在2005年*开始了一项土壤测试项目。此处描述的是过去的行为，故用一般过去时。

9．that/which　考查定语从句的引导词。此处为限制*定语从句，修饰先行词program，关系词在从句中作主语。故填that或者which。

10．feeding　考查状语从句的省略。句意：*在养活了**的同时又保护了环境。这一做法为全世界的农业和粮食政策制定人提供了很有用的经验。空格处表示正在进行的动作，while后面省略了China is。在时间状语从句、条件状语从句、让步状语从句中，如果从句的主语和主句的主语一致且从句的谓语动词含有be动词的某种形式时，可以省略从句的主语和be动词。故填feeding。
