1、示意未来或预计

I don’t know what is to happen to us. 我不晓得咱们会产生什么事。

I went to have a look at the room where I was to talk that afternoon. 我去看了一下处所,当天下战书我要在那里讲话。

It was 1491. Columbus was to reach America a year later. 那是1491年,1年后哥伦布达到了美洲。

申明:当该结构顶用了still或yet时,其未来意义更为凸起。如:

The worst is still to come. 还有最糟糕的事变要产生。

The most severe weather is yet [still] to come. 最卑劣的气候尚无到。

The best item on the programme is still to come. 最悦目的节目还在后头。

注重,该结构示意未来的用法是有限的,原则上,只有当示意的动作为人所节制时才可利用它来示意未来,否则就是错的。如可说 I’m going to play tennis,也可说 I’m to play tennis,由于其中的 play tennis是可以人为节制的。而在如下各例中,其中的动作均不能为人所限定,以是going不可省略:

He’s going to be fat. 他要发胖了。

There is going to be a storm. 要下暴风雨了。

You’re going to break that chair. 你会把那把椅子弄坏的。

2、示意筹划或用意

They are to be married. 他们计划完婚。

We are to be married in June. 咱们筹划在六月完婚。

申明:该结构也可用于前提状语从句。如:

If I’m to be there on time, I must leave at once. 要是我要想准时赶到那边,我就必需立刻起程。

If we are to succeed in this enterprise, we shall need to plan everything very carefully. 要是咱们想要在这项奇迹上获得胜利,咱们就必要把统统都细心筹划好。

此外,若示意过去未曾实现的设法或用意,其中的不定式则用完成式。如:

We were to have gone away last week, but I was ill. 咱们本计划上周走的,然而我病了。

I was to have started work last week, but I changed my mind. 我本该上周入手下手工作的,但我扭转了主张。

对比:

He was to go. 其时他是要去的。(至于末了去没去,不得而知)

He was to havegone. 他原先是要去的。(但实际上却没有去)
