should 作为情态动词表示应该;而过去将来时它的谓语构成形式是:助动词should/would+动词原形,或者was/were+going to +动词原形。should在这里是助动词,我们都知道助动词是没有词义的,只是表示否定,疑问,时态等语法功能.表示过去将来时英国人习惯于第一人称用should,其它人称用would,在美国各人称均用would. 如I said I should be there before ten.我说过我十点钟以前到那。We said we should finish the work soon,我们说过我们会很快完成那份工作的。本回答被提问者采纳

Should用于过去将来时,一般要使用倒置结构,即将Should提前到句子开头,使之成为状语从句。
例句:
Should I have listened to you, the situation now would be much better.
意为:如果我当时听了你的话,现在的情况就不会这么糟糕了。

should / would have done sth.
用法
1、 过去将来完成时表示在过去将来某一时间以前发生的动作,并往往会对过去将来某一时间产生影响。
We hoped that she would have got the plan ready before we came back. 我们希望她能在我们回来
之前把计划做好。
He said he would let me have the book as soon as he had read it. 他说书一看完就借给我。
2、 过去将来完成时还常用在虚拟语气中,表示与过去的事实相反。如:
If I had seen him this anteroom, I would have told him about it. 今天下午我要是见到他,我会
告诉他那件事的。
