问题
选择题
We have two rooms _______, but I can’t decide ________.
A．to live in, to choose which one
B．lived, choose which one
C．to live in, which one to choose
D．live, which one
答案
答案：C
题目分析：句意：我有两间可住的房间，但是我不能决定选择哪一个。动词不定式做名词的后置定语与所修饰词之间有逻辑上的动宾关系，所以动词不定式短语做后置定语，所带的介词不要丢掉。疑问词加动词不定式可以代替宾语从句做宾语。根据句意，故选C。
