题目内容
The professor could hardly find sufficient grounds _____his arguments in favor of the new theory.
A.to be based on B.to base on C.which to base on D.on which to base
【答案】
D
【解析】
试题分析:考查特殊不定式:on which 中的which指代sufficient grounds ,to base 中的base 是vt 。后接his argunents 做宾语,这句话结构其实就是 base his arguments on sufficient grounds in favour of the new theory,还有特殊不定式只能用主动形式,eg: I don't know what to do next ? 选D。
考点:考查特殊不定式
点评:不定式的特殊句式可以用来表示表示连动结构。不定式在做定语和做状语时都有其特殊句式,注意这些句式的特点,如: have something to do类:这类结构相当于汉语的连动结构,即"有事要做","买东西吃","借书看"等。a room in which to live:可以住的房子。
