问题
He fell asleep immediately last night. He ______ very tired.
选项
A、must be
B、must have been
C、can be
D、could have been
答案
B
解析
情态动词。此句是根据结果推测原因,推测做过的事情的原因用虚拟语气的形式来表示,即:must have done表示对过去事情的肯定性推测,注意其否定形式不是在must后面加not,而是用can或could来否定,称之为否定推测。[例句] This bottle is nearly empty,you must have drunk a lot.瓶子快空了,你一定喝了不少。
