I have experienced quite a number of cases ______ I really wanted to help but could not have anything to ______.
A．when; put on my hands
B．that; put my hands on
C．where; put my hands on
D．in that; put on my hands
答案
答案：C
本题考查定语从句中关系词的选择和动词短语做定语。定语从句的先行词是cases；后面的定语从句结构很完整，所以第一空使用关系副词where，在定语从句里做状语。to put my hands on这个不定式是修饰anything。
