选择题
—The police have caught the murderer.
—Yes, and he admitted ________ his boss on a rainy night seven years ago.
A．to kill
B．to have killed
C．having killed
D．have been killing
答案
答案：C
在delay, admit, avoid, suggest, advise, practise, finish, mind, enjoy等动词后,只跟动名词而不跟动词不定式作宾语。错答B者只考虑到kill动作发生在admit之前,但不知admit doing这一用法。
