GMAT时态问题?
Once they had seen the report from the medical examiner,the investigators
[did not doubt whether the bodyrecovered from the river was] the man who had attempted to escape from the state prison.
划线是[ ]
(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
这里有个疑问
1、 had done过去完成不是不能再接had done了吗,那为什么原句的后面跟了the man who had attempted?
2、had done 后边再接应该是用一般过去吧?表达了先后顺序 如果接一般现在是不是错误的?
3、这里BD的have时态是怎么对应的?..根据2我知道一般过去时对应的是was,但是has不太懂
以及,其他项怎么排除

Answer 1

先回答你的疑问：
1.the man had attempted 和第一句话里面的 they had seen the report所描述的不是同一个主语,也不属于一个单句.had seen the report的人是investigators; had attempted to escape 的是这个尸体的主人.这个复合句是由两个句子构成的,有两个层次,因此两个完成时可以并存.
2.这个疑问不存在,因为答案是E.用的是had,过去时.
3.BD都错在用了一般现在时态.
怎么排除其他的,有个最简单的方法是看重句的后半段,形容这个尸体的地方,the body was that of the man who.才比较合理.因为尸首不是一个人,而是属于一个人.body was not the man,body was that of the man.
