40、started 69. that/which 70. feeding61. 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
41、用非谓语动词。此处表示目的，故用不定式。故填 to improve。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。68. 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。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
42、。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
43、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
