问题补充:
They with each other for two years before they got married.
A. had fallen in love
B. got in love
C. had been in love
D. fell in love
答案:
A. had fallen in love
B. got in love
(答案→)C. had been in love
D. fell in love
解析:考查时态:句意:在结婚之前他们已经相爱两年了。Fall in love 为非延续性动词短语,不能与 for two years 连用,故排除 A、D 项。be in love 为表示状态的动词短语,可以与 for two years 连用。且 fall in love 这个动作发生在“got married”之前,故用过去完成时。选C。
