虚拟语气指的是当一个人说话时欲强调其所说的话是基于自己的主观想法，愿望，假想，猜测，怀疑或建议，而不是根据客观实际，就用虚拟语气。GMAT语法考试只考陈述语气和虚拟语气，而虚拟语气又是考试中的难点，所以本文给大家介绍的就是GMAT语法时态语气试题讲解之虚拟语气的第三部分。
例5：
Once they had seen the report from the medical examiner, the investigators did not doubt whether the body recovered from the river was the man who had attempted to escape from the state prison.
· A did not doubt whether the body recovered from the river was
· B have no doubt whether the body recovered from the river was
· C had not doubted that the body recovered from the river was
· D have no doubt whether the body recovered from the river was that of
· E had no doubt that the body recovered from the river was that of
分析：Once 引导一个从句，从句中的谓语是had seen这个过去完成时，看到过去完成时就要找过去时，只有划线部分才能体现过去时态了，句子主语 the investigators，doubt应该使用that呃关联词而不是whether，排除A，B选项have no doubt 时态错误，排除，C选项 had not doubted 过去完成时，时态错误，排除。D选项have no doubt 时态不对，whether换成that，排除。E选项，had no doubt过去时态没问题， doubt that使用正确，the body was that of the man ，正确。
正确句子：
Once they had seen the report from the medical examiner, the investigators had no doubt that the body recovered from the river was that of the man who had attempted to escape from the state prison.
验证：Once 引导一个从句，从句中的谓语是过去完成时，主句主语是the investigators，
谓语动词是had no doubt ，后面是个that引导的从句，从句主语是 the body ，谓语是was，后面还有一个who引导的是先行词 the man 的定语从句，因为 attempted肯定是在was之前，强调的是动作的先后顺序，没问题。
例6：
His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets had existed in now currently temperate areas.
· A in which great ice sheets had existed in now currently temperate areas
· B in which great ice sheets existed in what are now temperate areas
· C when great ice sheets existed where there were areas now temperate
· D when great ice sheets had existed in current temperate areas
· E when great ice sheets existed in areas now that are temperate
分析：His studies of ice-polished rocks in his Alpine homeland是个名词短语，far outside the range of present-day glaciers, 也是名词短语，因为前后都是逗号所以当做插入语就可以，句子主语就是His studies， led是谓语动词，lead的用法有两种，一种是lead somebody to do引导某人做某事。还有一种是,lead in doing。led Louis Agassiz in 1837 to propose the concept 所以这句话没问题，画线句子存在用词重复的问题， now 和currently，排除A。B选项，没有问题。C选项，there were areas now temperate 中因为是now，所以使用were不好，there be 结构本来就是个倒装结构，所以肯定不能说there是句子的主语，这个句子的主语是areas ，谓语 were，temperate 是形容词做的表语，那么where很明显就是状语，定语从句的特点就是关系词在定语从句中一定要充当成分，所以where一定是要充当成分的，在这个句子中是多余的，排除C。D选项had existed 过去完成时态，至少句子当中要有过去时态的谓语动词才行，所以时态不对，而且时间状语是current ，但是没有谓语动词来体现，是错误的，排除D。E选项， when 引导的时间状语从句没问题， now时间状语放的位置不对，放在这里existed 应该使用一般现在时态，但是其实now修饰的是后面that从句中的谓语动词，排除E.
正确句子：
His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets existed in what are now temperate areas.
验证：
His studies 句子主语，谓语动词是led,propose 是一个动词，后边的宾语是concept，age 是抽象词所以用in which，在这里when也可以，now 表示的谓语是一般现在时 are正确。
