must be语气强硬的,“必须、一定”之意
can be语气不确定,“可能”之意
can't be语气偏强硬,“不可能”之意
may be语气比can be还不确定,表示“可能、或许”之意
说区别
must be语气最为强烈,说话者主观肯定超过90%
比如:You must be John!你一定是John!(不可能是别人)
can be 确定度就只有50%
比如:You can be a good painter in the future.你将来可能会成为一个好画家(也可能会不可能成为画家,只是语气比较偏向于肯定,虽然可能性对半)
can't be是一种否定语气用法,但主观语气确定性大过50%
比如:You can't be John!你不可能是John.(半带猜测的否定,“你应该不可能是的”)
may be是确定度只有20%左右的用法
比如:It may be raining all day.今天可能会下一整天的雨.(确定度很低,仅仅是猜测)
