A.and whether, presuming such life forms having left fossil traces to begin with, those traces can
B.and whether, if it is presumed that such life forms left some fossil traces to begin with, can those traces
C.and whether, presuming such life forms left fossil traces to begin with, those traces
D.and, presuming such life forms did leave some fossil traces to begin with, if they can
E.and, presuming such life forms to have left fossil traces to begin with, if they
问道题目，答案是C，我想问下，当中的presuming such life forms left fossil traces to begin with算是插入语吗？另外presume后面的宾语从句后面不用加that的吗？大家还知道哪些动词的宾语从句后面是不用加that的？我知道say后面好像不用加that的作者: anguslu24 时间: 2011-6-22 17:16
动词ing作状语。。。可以提前或者插中间。。persume (that) 省略了 BDE有if表“是否”，直接杀，A用persuming... having...时态不对，杀 就是C了。。作者: Joseph_lin 时间: 2011-6-22 19:09
分词一共可以做2中状语，一种是结果状语，一种是伴随状语，这里好像一个都不是唉？作者: Joseph_lin 时间: 2011-6-29 15:48

2楼分析的很对啊，LZ不要太纠结去套他到底是什么状语 （可能是因为本人特别怕那些术语。。。见谅），而是应该直接剖析句子的逻辑结构。看出首先他是presume (that)....后面自然要跟一个独立的结构。同时whether后面也是要跟一个独立结构。考试的时间很紧张，直接whether的方法排除BDE，A的presume后面结构悬垂，C正确。
