--Do you think you will give me a hand in time of trouble?
--I’d like to do something for you everything you’ve done for me.
A. in exchange
B. in turn
C. in return for
D. in terms of

A. in exchangeB. in turn (答案→)C. in return for D. in terms of解析：词义辨析。A项不全，应该有介词for; in turn依次，轮流；in return for作为…的回报；in terms of就…而言。句意：—在紧急情况下，你会帮助我嘛？—我会为你做的作为你位我们做的事情的回报。根据句意说明C正确。

哦，回答的不错
