如果主句是将来时，从句中能不能用to来表将来，to有什么用法和意义

Question

如题所述

Answer 1

这个问题很是不清楚呀。什么叫做“to来表示将来”。如果楼主能给个例子就能很好的让人家理解你的意图。
从要看什么类型的复合句来讨论。
1.　如果是条件、时间等状语从句。那么主句是将来，一般从句是现在时。如: I will go hiking if it is not rain tomorrow. I wil take care of him when he returns from the hospital.
2. 如果是定语从句，那么要根据语义定从句时态。
　I will go to meet a former teacher who is going to attend the conference in my college.
I will catch the train that is to arrve at the station at 10 o'clock.
3. 宾语从句和其他名词性从句也会依具体语义而定。追问

开头是to 的那种，比如 别人邀请我参加聚会，我将要去 用开头是to的那种，可不以表将来

追答

to do是不能用于从句或主句谓语的，因为是非谓语动词形式。你干脆写个句子，别人邀请我参加聚会，我将要去。那也是：I was invited to a party, I am going now.

Answer 2

To make good grades , I will study hard .
可以，这句话就是为了取得好成绩，我将努力学习。to表目的，表将来。
