第一个问题,可以,两种说法都对
第二个,must be 意思是说,说话的人很确定这个人就是li lei不能用can be,因为和整个语境不符
be going to 表示有计划的,主观的. 可以用will代替,但意境有点不一样.
must be 一定是
can't be 不可能是
can be 可能是
如果用can be代替must be 表达的意思不一样
1.可以
都是将来式，be doing sth
2.没有这种说法
如果要用的话要用may ,表可能
不可以 趋向动词 go come fly leave 一般都用－ing 形式表将来时态

相似的有I am leaving in 5 mins.我将要在5分钟之内离开.
2. A:that boy must be li Lei.
B:he can't Li Lei ...
