We ________ last night, but we went to the concert instead, so we failed in the examination.
A.should study
B.must study
C.should have studied
D.must have studied
答案及解析: C
C句意:我们昨天晚上应该学习,而我们却去听音乐会,所以我们考试不及格。由此可知句意是责备我们昨晚本该学习而没有学习,却去听音乐会。“should(ought to) have done”结构意为“本来应该……”,表示过去应该做或值得做的事情而没有做到,含有后悔、埋怨、责备等意味。
