选A

A 伴随状语，海洋（在保持人类生存的条件下）扮演了一个重要的角色， moderating和 giving pure water是扮演重要角色的2个方面，（1）恒温（2）水源，所以作伴随状语修饰play这个动作
B and giving pure water无平行对象
C cover和 play 在逻辑上不平行，因为起作用肯定是基于覆盖71%的地球表面也可以，假如不覆盖，再怎么样也不会对人类生存有影响/// and by moderating前面无平行
D 最后一个and giving pure water 无平行
E 同D

靠语感能做出来的，就不用逐个看选项了吧，这样会节省时间

笑死，Amanda就在方法课说过，除非你看了很多GMAT rc阅读的文章，才可以说语感这种东西，sc不能靠语感

看到and giving pure water，前面也要与之平行，所以看选项末找ing，and by moderating结构错误，选择A

求问DE的主干改变是指什么呢？

哎呀

考点：平行逻辑语义分析：主干是covering...,the oceans play role in maintaining...,moderating...,and giving... 选项： A.正确，covering分词短语放句首作状语，逻辑主语是the ocean；3个宾语平行，maintaining， moderating，and giving... B.playing在句中变成状语，句子主干发生改变，and giving无平行对象； C.主干发生改变，cover变成谓语，逻辑语义改变，maintaining ，and by moderating ,and giving不平行； D.同C，主干改变；maintaining and moderate and giving不平行； E.同CD，主干改变；and they moderate不平行；
