问题 I am sorry. I______finished it by last Monday, but I have been too busy.

选项 A、must have
B、may have
C、ought to have
D、might have

答案C

解析 此题测试的是情态动词完成式的含义和用法。ought to have(done)具有虚拟含义,与should(not)have(done)类似,表示“本应该(本不该)做某事但实际上未做(做了)”,符合题意要求:“我应该上星期一前就做完这件事,可是我一直太忙了,真抱歉”;may have(done)和might have(done)“也许做了某事”,后者可能性更小;must have(done)表示对过去情况的肯定推测,均与句意不符。
