记得学习英语过去将来时语法详解
在学习、工作、生活中，大家都收藏过令自己印象深刻的句子吧，借助句子，我们可以更好地表达。那什么样的句子才具有启发意义呢？以下是帮大家整理的英语过去将来时语法详解句子，欢迎大家分享。
过去将来时的结构
过去将来时由“would+动词原形”构成，主要表示从过去某一时间来看将要发生的动作(尤其用于宾语从句中)。如：
She said that she wouldn't do that again. 她说她再不会这样做了。
He promised that he would help me. 他答应他会帮助我。
对于一个谓语动词用一般将来时的句子，如果将它置于一个主句谓语为过去式的宾语从句中，那么原来的一般将来时就要变为过去将来时，因为此时对于宾语从句来说，时间的基点从现在移到了过去。比较：
He will agree. 他会同意的。
I knew he would agree. 我当时就知道他会同意的。
过去将来时的用法
1、表示从过去的某一时间来看将来要发生的动作或存在的状态。过去将来时常用于宾语从句和间接引语中。
例句：I didn't know if he would come. 我不知道他是否会来。 (指过去不知道。)
She told us that she would not go with us，if it rained. 她告诉我们，如果下雨，她就不和我们一起去了。
2、过去将来时常可用来表示过去习惯性的'动作。此时，不管什么人称，一律用would。
Whenever he had time，he would do some reading. 他一有时间，总是看书。
3、表示主管打算、计划要做的事情或根据过去的某种迹象做出的推测，用was/were going to+动词原形表示 .
例句：Last Sunday we were going to visit the Great Wall, but it rained. 上星期天我们本想去游览长城的，但却下雨了。
过去将来时的各种句型
同一般将来时，把系动词be变为过去式，把will，shall变为过去式。句型如下：
肯定句：主语+be(was，were)going to+动词原形+其他
否定句：主语+be(was，were)not going to+动词原形+其他

英语语法入门之过去时态
There are two tenses in English – past and present.
英语里有两种时态—过去时和现在时。
The past tense in English is used:
英语里过去时用于：
to talk about the past
谈论过去
to talk about hypotheses – things that are imagined rather than true.
谈论假设
for politeness.
基于礼貌
There are four past tense forms in English:
We use these forms:
to talk about the past:
He worked at McDonald’s. He had worked there since July.
He was working at McDonald’s. He had been working since July.
to refer to the present or future in conditions:
He could get a new job if he really tried.

and hypotheses:
It might be dangerous. Suppose they got lost.
I would always help someone who really needed help.
and wishes:
I wish it wasn’t so cold.
In conditions, hypotheses and wishes, if we want to talk about the past, we always use the past perfect:
在条件状语从句、虚拟语气以及表祝愿时，我们在谈论过去时，经常使用过去完成时。
I would have helped him if he had asked.

We can use the past forms to talk about the present in a few polite expressions:
在一些礼貌的表达中，我们用过去式来谈论现在的事情。

I just hoped you would be able to help me.
