【摘要】掌握好英语语法对于同学们学好英语有很重要的作用，小编为大家整理了英语六级语法：过去完成时知识点，希望大家喜欢。
一般过去式和过去完成时的对比：
(1)过去完成时：
过去的过去;
eg：Before I came to Beijing, I had stayed in Shanghai.
① 一个句子里有两个谓语动词，一个发生在前，一个发生在后，发生在前的用一般过去时，发生在后的用过去完成时;
eg：When the police arrived, the thieves had run away.
② 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，却未能…"
eg：We had hoped that you would come, but you didn't. We had thought that he would take part in the competition，but he didn't.
③ 虚拟语气：
若虚拟的现象与过去事实相反，则用过去完成时;
eg：If you had come to my birthday party, you would have seen Yaoming.
虚拟语气中可以用had+过去分词，表示对过去事实的虚拟;
3. 一般将来时
(1)shall/will, shall用于第一人称，常被will 所代替;
eg：Which paragraph shall I read first?
(2)be going to +不定式，表示将来;表示要发生的事情有了预先的计划、准备或有迹象表明要发生;
eg：What are you going to do tomorrow?
What will you do this afternoon?
will表示纯粹的将来;
(3)be +不定式：表将来，按计划或正式安排将发生的事;
eg：We are to/will discuss the report next Saturday.
(4)be about to +不定式：意为马上做某事，后面不可以接时间状语;
eg：He is about to leave for Beijing.
注意：
(1)一般现在时有时也可表将来;
eg：The train leaves at six tomorrow morning.
① 趋向性动词come, go, arrive, leave, start, begin, return的一般现在时表将来，主要用来表示在时间上已确定或安排好的事情。
eg：When does the bus star? It stars in ten minutes.
② 在时间或条件句中，用一般现在时表将来;
eg：I'll write to you as soon as I arrive in Beijing.
(2)现在进行时也可表将来：通常用于口语，翻译为打算……;
come, go, start, arrive, leave, stay等词可以用进行时表将来;
