在學(xué)習(xí)、工作、生活中，大家都收藏過令自己印象深刻的句子吧，借助句子，我們可以更好地表達(dá)。那什么樣的句子才具有啟發(fā)意義呢？以下是小編幫大家整理的英語(yǔ)過去將來時(shí)語(yǔ)法詳解句子，歡迎大家分享。
過去將來時(shí)的結(jié)構(gòu)
過去將來時(shí)由“would+動(dòng)詞原形”構(gòu)成，主要表示從過去某一時(shí)間來看將要發(fā)生的動(dòng)作(尤其用于賓語(yǔ)從句中)。如：
She said that she wouldn't do that again. 她說她再不會(huì)這樣做了。
He promised that he would help me. 他答應(yīng)他會(huì)幫助我。
對(duì)于一個(gè)謂語(yǔ)動(dòng)詞用一般將來時(shí)的句子，如果將它置于一個(gè)主句謂語(yǔ)為過去式的賓語(yǔ)從句中，那么原來的一般將來時(shí)就要變?yōu)檫^去將來時(shí)，因?yàn)榇藭r(shí)對(duì)于賓語(yǔ)從句來說，時(shí)間的基點(diǎn)從現(xiàn)在移到了過去。比較：
He will agree. 他會(huì)同意的。
I knew he would agree. 我當(dāng)時(shí)就知道他會(huì)同意的。
過去將來時(shí)的用法
1、表示從過去的某一時(shí)間來看將來要發(fā)生的動(dòng)作或存在的狀態(tài)。過去將來時(shí)常用于賓語(yǔ)從句和間接引語(yǔ)中。
例句：I didn't know if he would come. 我不知道他是否會(huì)來。 (指過去不知道。)
She told us that she would not go with us，if it rained. 她告訴我們，如果下雨，她就不和我們一起去了。
2、過去將來時(shí)�？捎脕肀硎具^去習(xí)慣性的動(dòng)作。此時(shí)，不管什么人稱，一律用would。
Whenever he had time，he would do some reading. 他一有時(shí)間，總是看書。
3、表示主管打算、計(jì)劃要做的事情或根據(jù)過去的某種跡象做出的推測(cè)，用was/were going to+動(dòng)詞原形表示 .
例句：Last Sunday we were going to visit the Great Wall, but it rained. 上星期天我們本想去游覽長(zhǎng)城的，但卻下雨了。
過去將來時(shí)的各種句型
同一般將來時(shí)，把系動(dòng)詞be變?yōu)檫^去式，把will，shall變?yōu)檫^去式。句型如下：

英語(yǔ)語(yǔ)法入門之過去時(shí)態(tài)
There are two tenses in English – past and present.
英語(yǔ)里有兩種時(shí)態(tài)—過去時(shí)和現(xiàn)在時(shí)。
The past tense in English is used:
英語(yǔ)里過去時(shí)用于：
to talk about the past
談?wù)撨^去
to talk about hypotheses – things that are imagined rather than true.
談?wù)摷僭O(shè)
for politeness.
基于禮貌
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.
If Jack was playing they would probably win.
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:
在條件狀語(yǔ)從句、虛擬語(yǔ)氣以及表祝愿時(shí)，我們?cè)谡務(wù)撨^去時(shí)，經(jīng)常使用過去完成時(shí)。
I would have helped him if he had asked.
It was very dangerous, What if you had got lost?
I wish I hadn’t spent so much money last month.
We can use the past forms to talk about the present in a few polite expressions:
在一些禮貌的表達(dá)中，我們用過去式來談?wù)摤F(xiàn)在的事情。
Excuse me, I was wondering if this was the train for York.
I just hoped you would be able to help me.
