They must have gone there two days ago,did not they?We must go right now,need not we?
问题描述:
They must have gone there two days ago,did not they?We must go right now,need not we?
二句都有must,为何反义疑问句的句末不一样呢?
did not they?与need not we?
答
两个句子的must 含义不一样
第一句must have gone :一定是已经去过那儿了,must用于强调过去发生的事实以及说话人的肯定程度.
第二句must go right now:我们必须现在就要出发,must表示必须的程度,说话人的意思是想问,是不是真的需要现在就出发.
