英語過去將來時(shí)語法詳解

　　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過去將來時(shí)語法詳解句子，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)主句謂語為過去式的賓語從句中，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)常用于賓語從句和間接引語中。

　　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)常可用來表示過去習(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，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：

　　肯定句：主語+be(was，were)going to+動(dòng)詞原形+其他

　　否定句：主語+be(was，were)not going to+動(dòng)詞原形+其他

　　疑問句：Be(Was，Were)+主語+going to+動(dòng)詞原形+其他

　　英語里過去時(shí)用于：
