It __________ Tom that parked the car here, as he is the only one with a car. A．may be B．might have been C．must have been D．could be

Answer 1

C

试题分析：考查推测，might have done表示对过去事情不肯定推测； must have done表示对过去事情肯定推测；could have done表示表示过去未实现的动作，由后面的句子as he is the only one with a car可以知道是肯定推测，所以选C 点评：推测是常考内容，要知道它们表示的是什么意思，遇到此类题时，就很容易做出正确选择
