Question

— Li Lin hasn’t turned up yet, but he promised to come to the party.
— He ______ home. He is a man of keeping his word.

A．can’t leave	B．won’t be leaving
C．could have left	D．must have left

Answer 1

D

试题分析：句意：——李林还没来，但他答应过要来参加聚会的。——他肯定已经从家里出来了。他可是个信守诺言的人。从He is a man of keeping his word中可以看出，李林肯定已经出发来参加我们的晚会，这是对已发生的事肯定的推测，故用情态动词完成式。注意must用作推测意义时，不能用于否定式和疑问句。can’t leave肯定没有离开；won’t be leaving将不愿意离开；could have left本来可以离开的。
