【分析】
本文是一篇说明文。文中讲述了中国为保护环境在农作物种植上做了一些变化并得到了世界上的知名认识的认可。
66.考查时态。since加时间点,主句要用现在完成时。句意:2011年以来,中国种植的玉米比水稻多。故填has grown。
67.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%。故是特指在过去的25年里。故填the。
68.考查副词。句意:对肉的需求实际上是这种变化的背后原因。句子结构完整,用副词修饰句子。故填actually。
69.考查非谓语动词。句意:为了改善水质政府鼓励农民种植玉米而不是大米。没有连词可以且谓语动词是encourages,故improve应该用非谓语动词。此处表示目的,故用不定式。故填to improve。
70.考查连词。句意:玉米比大米使用的水更少。根据关键词less可知,填比较连词。故填than。
71.考查词性转换。句意:这一转变减少了中国较大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。
72.考查词性转换。句意:中国约占全球化肥总消费量的30%。fertilizer consumption是名词短语,故应该用形容词修饰。故填global。
73.考查谓语动词。句意:在2005年政府开始了一项土壤测试项目。本句是when引导的定语从句,由于时间是2005年,故用过去时。故填started。
74.考查定语从句关系词。根据空后的谓语动词gives可知,该空缺少主语,指代program并且引导后面的句子。指物用that/which,故填that或者which。
75.考查省略句。句意:中国在养活了中国人民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后面省略掉了China is,省略句的原则: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含有be动词时,那么可以把主语和be动词一块省略。故填feeding。
点睛: 两个破折号中间只有一个定语从句,破折号中间的所有内容起到解释说明作用,本题中的是状语成分,when引导的是一个时间状语从句,状语从句中含有一个含空的定语从句。由于从句中须有一个谓语动词所以小题9看句意用过去时。
