题目内容
He made another wonderful discovery,_____ of great importance to science.
A.which I think is |
B.which I think it is |
C.which I think it |
D.I think which is |
A
解析试题分析:通过分析句子结构,可知这个句子中包含一个非限制性定语从句,I think是插入语,要放在which之后,故选 A。
考点:定语从句中的插入语考查
点评:构成插入语的成分可以是单词、短语或是句子,用来补充含义或作出一些解释,把插入语从原文中抽取出来,句子结构不会发生变化。如果插入语过长,我们可以先略过这部分,等从整体上把握句意之后再回头看插入部分的内容。
