就是要记得.
②你想想must have happened 怎么翻,大意是过去肯定发什么了,是这个意思吧,既然都肯定了还怎么用疑问?
③may 要是用于疑问句都表请求征求的意思了,对不对?我们经常说的May i come in
④can 还有个特殊用法,估计楼主高一还没学到:表示理论的猜测
现在,我们联系情景看下,我已经几周没见white了.在他身上发生了什么?大概就这意思,要我精确翻我也不会.
楼主懂没?

must have done 是固定搭配 表对过去的肯定推测 不可用于疑问
may have done 表对过去的推测 也不可用于疑问
B可以

can have done 表推出只用在否定句和疑问句中
而A,C只用于肯定推测

就是must must 在表示推测时,不能用于疑问句,二CAN行

must have 在肯定句中的意思是一定,或者是较为肯定的猜测。如果是用在否定句中,表示不准。所以不能用于疑问句。may have 一般用于陈述句或否定句,表示较不肯定的猜测,同样也不能用在疑问句。而将答案带入原题,意思应为:什么事会发生在他身上?...
