26、与解析【语篇导读】本文是一篇说明文。文章介绍了中国的农作物玉米的产量逐年增加的原因。种植玉米,不仅可以喂养牲畜,而且因为其生长过程浇水施肥较少,还可以减少对环境的污染,进而保护环境。1.has grown 考查动词时态和主谓一致。根据该句中的时间状语“Since 2011”可知,此处应用现在完成时,且该句的主语是“the country”,故谓语动词用单数形式。2.the 考查冠词。根据句意可知,此处特指“过去的 25 年”,故应用定冠词 the 表示特指。3.actually 考查副词。根据后文的介词短语“behind the change”可知,此处应用 actual 的副词形式,故填 a

27、ctually。4.to improve 考查非谓语动词。此处是不定式做目的状语,故填 to improve。句意:政府鼓励农民种植玉米而非稻米,目的是提高水质。5.than 考查形容词的比较级。根据前面的 less 可知,此处是形容词的比较级,故缺少连接词than。6.pollution 考查名词。根据空前的“decreased”可知,空处应该是名词做宾语,意思是“减少污染”,故填 pollution。7.global 考查形容词。此处 fertilizer consumption 是名词词组,其前面需要用形容词修饰,故填 globe 的形容词形式。8.started 考查动词的时态。根据句中的时间状语“between 2005”可知,此处描述的是过去发生的事情,故用一般过去时。9.that/which 考查定语从句。分析句子结构可知,空处引导定语从句,且在从句中做主语,修饰先行词 a soil-testing program,故填 that 或 which。610.feeding 考查特殊句式。while doing sth.“当做某事的时候”,它是 while sb. is/was doing sth.的省略形式,故此处应填 feeding。
