选择题
------Thank you very much for giving me a hand when I was in trouble.
------Don’t mention it. I only did what anyone else _______ in my place.
A．must do
B．might do
C．would have done
D．can have done
答案
答案：C
考查情态动词用法。根据 for giving me a hand when I was in trouble可知，此处是对故去的虚拟，排除AB. Would have done意为我只是做了别人都会做的事情。 Can have done意为可能做了某事，不符合题意。
