64. 考查动词的时态。医学报告显示：跑步比散步、骑车和游泳更能有效地延长寿命。这里叙述的是一个事实，故用一般现在时。故填is。

65. 考查比较句型。跑步比散步、骑车和游泳更能有效地延长寿命。根据文章中的more effective可知此处填than。

66. 考查定语从句的关系词。此处a study是先行词，其在定语从句中作主语，故填that或which。

点睛：本文比较难的一个题是10题。短语give it a try不容易想出来。give a try试试。Give sb sth； give sth to sb这些短语学生都很清楚。但give后加it或sth的形式，比较少见。高考复习要尽可能多的复习相关的短语，尤其是用的比较多，而课本中出现较少的短语。

【解析】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。

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。

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。
