be to do表示将来做某事,但表将来正在做某事是be to doing?
是will be doing?若是有be to doing 怎么区别?我语法不好.

按照我的分析,你英爱是把谓语和非谓语弄混了：
be to do谓语,是将来时的一个结构,表示“安排”（现在安排好某件事,在将来发生）,例如：We are to have a meeting tomorrow afternoon.；表示“注定要发生”.
will be doing谓语,是将来进行时,表示将来某时刻正在发生.
be to doing,你应该是写错了,是非谓语,应该是to be doing,是动词不定式的进行式,表示与谓语同时发生.

be to do表示将来做某事,但表将来正在做某事是be to doing? 请问英语中有没有表示将来能做某事的 can be + to do 的形式? 被看见正在做某事是to be doing 还是doing? 用来做某事是be using to do还是be using to doing,要有依据 “习惯于做某事”是be used to doing sth,那“习惯某事”是be used to 值得做某事的英语是be worth doing还是beworth to do 能够做某事是be able to do sth还是doing sth used to do sth 过去常常做某事 be used to doing sth习惯于做某事之类的用法将来时有BE DOING么?be going to do和BE DOING是算在现在进行时表将来? be equal to doing sth?胜任做某事? will,be going to do,be doing表将来被要求做某事是be made to do还是be made do
