They ______ because the light’s on!
选项
A、must have gone out
B、can’t have gone out
C、mustn’t have gone out
D、can’t go out
答案
B
解析
此题考查情态动词的用法。表示推测时,肯定形式用must,否定形式用can’t一般表示对事实有根据的否定推测。如:He can’t be in the house;he went out half an hour ago.他不可能在家,半小时前他就出去了。can后接动词的完成时态表示某人可能已经做了某事或某事已发生,或者由虚拟语气延伸而表示“能而未”。如:Where can he have gone?他能去哪儿了呢?Many women could have had very good positions
