题目
题型:不详难度:来源:
He ______ it on schedule, but somehow he fell behind.
A.must have doneB.might finish
C.could have finishedD.could finish

答案
C
解析

试题分析:句意为:他本能够按时完成任务,但他莫名其妙的落后了。must have done 对过去发生的事情的肯定推测,译为“一定---”;might do对现在发生的事情的肯定推测,译为“也许---”语气不十分肯定;could have done意为“本能够---”;could do 用于虚拟语气,对现在或将来的事情虚拟。
