I didn't hear the phone.I must have been asleep.我刚才没有听到电话,我想必是睡着了
复合谓语有一句说助动词或情态动词加动词原形构成复合谓语.
我想问上面一句话 I must have been asleep 这句话构成谓语是哪几个词?

解答

谓语：asleep
"have been"只代表它是现在完成时
must表推测没错情态动词用完成时推测但是asleep是形容词啊？难道是must asleep? 也不是啊！be asleep 这不是谓语。这是主系表结构be asleep 相当于sleep你确定吗？我不太确定恩I am asleep变为现在完成时 I have been asleep. 你可以还原句子时态。句型就一目了然了
