Be you free tomorrow afternoon?表达是否有误?
应该是Are you free tomorrow afternoon吧?
但为什么下面的讲解用的是"be"呢?只是句型讲解还是能这样表达呢?
1.Will you be free this afternoon?
Yes,I’ll be free this afternoon.
2.Will she be free on Sunday morning?
Yes,she’ll be free on Sunday morning.
3.Will he be free next week?
Yes,he’ll be free next week.
4.Will they be free this afternoon?
Yes,they’ll be free this afternoon.
5.Will you be free tomorrow afternoon?
No,I won’t be free until evening.

因为有will,will用在将来时,后面跟的是原型动词,所以是be

因为WILL是将来时,后面接动词原型,所以只能用BE

没有错,但那时老式英语,早淘汰了.

你可以说are you free tomorrow afternoon?(可以接受,但比较少这样子表达)
也可以说will you be free tomorrow afternoon?
但这种情况是只限於主语是you的时候,其它时候是不能这样子用的?
