一英语BE的用法问题
1.Hurry up!he must be waiting for us at the station.
这里为什么是must be waiting 去掉be must waiting
wait 也是动词啊?这些情态动词什么时候后面根be 什么时候
2.you will be sleepy.改成一般疑问句是 will you be sleepy 这里的前一个will 是情态动词还是将来时的那后一个will呢?

1,must be doing 表示对正在做的事情进行推测.另外,must是情态动词,后面不能加doing,所以must waiting肯定不对
2,will在时态上表示将来,词性上是情态助动词.这里的两个will都是这样.
有问题继续问我,我是英语老师
