A taste for meat is ___63___ (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle.

61. 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。62. 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。
63. 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。
64. 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。
65. 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。
66. 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。
67. 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。

69. 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。
70. 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：学会分析句子成分。The Chinese Ministry of Agriculture finds that between 2005 - when the government started a soil-testing program which /that gives specific fertilizer recommendations to farmers - and 2011，fertilizer use dropped by 7.7 million tons. 这句话中有两个定语从句。一个是关系副词when引导的定语从句，先行词是2005，the government是主语，a soil-testing program是宾语，故此空缺少谓语动词，我们可以看出时态是一般过去时。另一个是关系代词指代program引导的定语从句，先行词是program，gives是第三人称谓语动词，可以看出是考查关系词。代指物并作主语，关系词要用that/which。
