【回答】

篇章導讀：本文是一篇説明文。文章講述了*為保護環境對農作物的種植做了一些調整。

1．has grown　考查動詞的時態。since後接時間點，句子要用現在完成時。句意：2011年以來，*種植的玉米比水稻多。故填has grown。

2．the　考查冠詞。句意：玉米產量在過去25年裏增長了近125%，而大米只增長了7%。此處特指在過去的25年裏。故填the。

3．actually　考查詞*轉換。句意：對肉的喜愛實際上是這種變化背後的原因。此處用副詞修飾be動詞is。故填actually。

4．to improve　考查非謂語動詞。句意：為了改善水質，*鼓勵農民種植玉米，而不是水稻。此處用不定式表示目的。故填to improve。

5．than　考查連詞。句意：玉米比水稻使用的水更少。根據關鍵詞less可知，應填用於兩個事物進行比較的連詞。故填than。

6．pollution　考查詞*轉換。句意：這一轉變減少了*主要的湖泊和水庫的污染，使人們的飲用水更加安全。has decreased後跟名詞作賓語，故填pollution。

7．global　考查詞*轉換。句意：*約佔全球化肥總消費量的30%。fertilizer consumption是名詞短語，應該用形容詞修飾。故填global。

8．started　考查動詞的時態。句意：在2005年*開始了一項土壤測試項目。此處描述的是過去的行為，故用一般過去時。

9．that/which　考查定語從句的引導詞。此處為限制*定語從句，修飾先行詞program，關係詞在從句中作主語。故填that或者which。

10．feeding　考查狀語從句的省略。句意：*在養活了**的同時又保護了環境。這一做法為全世界的農業和糧食政策制定人提供了很有用的經驗。空格處表示正在進行的動作，while後面省略了China is。在時間狀語從句、條件狀語從句、讓步狀語從句中，如果從句的主語和主句的主語一致且從句的謂語動詞含有be動詞的某種形式時，可以省略從句的主語和be動詞。故填feeding。
