英語過去將來時語法詳解

  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。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語法詳解句子,歡迎大家分享。

英語過去將來時語法詳解

  過去將來時的結(jié)構(gòu)

  過去將來時由“would+動詞原形”構(gòu)成,主要表示從過去某一時間來看將要發(fā)生的動作(尤其用于賓語從句中)。如:

  She said that she wouldn't do that again. 她說她再不會這樣做了。

  He promised that he would help me. 他答應(yīng)他會幫助我。

  對于一個謂語動詞用一般將來時的句子,如果將它置于一個主句謂語為過去式的賓語從句中,那么原來的一般將來時就要變?yōu)檫^去將來時,因為此時對于賓語從句來說,時間的基點從現(xiàn)在移到了過去。比較:

  He will agree. 他會同意的。

  I knew he would agree. 我當時就知道他會同意的。

  過去將來時的用法

  1、表示從過去的某一時間來看將來要發(fā)生的動作或存在的狀態(tài)。過去將來時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?捎脕肀硎具^去習(xí)慣性的動作。此時,不管什么人稱,一律用would。

  Whenever he had time,he would do some reading. 他一有時間,總是看書。

  3、表示主管打算、計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。

  過去將來時的各種句型

  同一般將來時,把系動詞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+動詞原形+其他

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

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

  肯定句:主語+would(should)+動詞原形+其他

  否定句:主語+would(should)not+動詞原形 +其他

  疑問句:Would(Should)+主語+動詞原形+其他

  英語語法入門之過去時態(tài)

  There are two tenses in English – past and present.

  英語里有兩種時態(tài)—過去時和現(xiàn)在時。

  The past tense in English is used:

  英語里過去時用于:

  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:

  在條件狀語從句、虛擬語氣以及表祝愿時,我們在談?wù)撨^去時,經(jīng)常使用過去完成時。

  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.
