英語過去將來時語法詳解
在學習、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。
過去將來時的結構
過去將來時由“would+動詞原形”構成,主要表示從過去某一時間來看將要發生的動作(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為過去將來時,因為此時對于賓語從句來說,時間的基點從現在移到了過去。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生的動作或存在的狀態。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、過去將來時常可用來表示過去習慣性的動作。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變為過去式,把will,shall變為過去式。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
There are two tenses in English – past and present.
英語里有兩種時態—過去時和現在時。
The past tense in English is used:
英語里過去時用于:
to talk about the past
談論過去
to talk about hypotheses – things that are imagined rather than true.
談論假設
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,我們在談論過去時,經常使用過去完成時。
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,我們用過去式來談論現在的事情。
Excuse me, I was wondering if this was the train for York.
I just hoped you would be able to help me.
