過去將來時分析和總結(jié)

1、過去將來時過去將來時:表示從過去的某一時間來看將來要發(fā)生的動作戒存在的狀態(tài)。過 去將來時常用于賓語從句和間接引語中。去將來時的出發(fā)點是過去，即從過去某一時刻看以后要發(fā)生的動作戒狀態(tài)。過 去將來時表達(dá)法：would+動詞原形例如：When you asked Li Lei for help, he would never refuse you.was/were going to+動詞原形例如：He told ustaht he was going to attend the meeting.was/were lo+動詞原形例如：Li Lei was to arrive soon. 4. was/

2、were about to+動詞原形例如：We were about to leave there when it began to rain heavily and suddenly.5. was/wcrc+現(xiàn)在分詞例如：He was leaving the next day.句型結(jié)構(gòu)：肯定句：主語+be, was, were, going to+動詞原形.否認(rèn)句：主語+bc, was, were, not going to+動詞原形.疑問句：Be, Was, Were, +主語+going to+動詞原形？肯定句：主語+would, should, +動詞原形.否認(rèn)句：主語+would,

3、should, not+動詞原形.疑問句:Would, Should, +主語+動詞原形?過去將來時的構(gòu)成和一般將來時一樣，只不過把助動詞be變?yōu)檫^去式，把will, shall 變?yōu)檫^去式。例句：I didnt know if he would come. =1 dicin t know if he was going to come.我不知道他是否會來。過去將來時具體用法：一、would+不定式.用“would+不定式”表示過去將來時間通常帶有表示過去將來的時間狀語， 而且多見于附屬分句。He said he would come back the next day.如果要表示在過去將來某

4、一時間正在進(jìn)行得動作，可用“would+不定式進(jìn)行 體”。例如：He never imagined that some day he would be living away from hismotherland.這種“would+不定式進(jìn)行體”結(jié)構(gòu)也可能僅僅表示一般過去過去將來時間，如 同“will/shall+不定式進(jìn)行體”表示一般將來時間一樣。、例如:He told me that Mary would be coming the next day.如果要表示在 過去將來某時以前業(yè)已發(fā)生得事態(tài)，可用“would+不定式完成體”。例如：The delegation would have a

5、rrived by four oclock that afternoon.如果要表示從過去某時開始一直延續(xù)到過去將來某時得動作戒事態(tài)，可用“would+不定式完成進(jìn)行體”。例如：She said that by the end of May she would have been studying medicine forthree years二、was/were going to + 不定式用做表示過去將來，也通常帶有表示過去將來時間得狀語。例如：He said that he was going to live in the country when he retired.用做表示的動作戒

6、事態(tài),也可以是沒有實現(xiàn)的意圖。例如：Last Sunday we were going to go for a picnic but it rained .三、was/were to +不定式用做表示過去將來，通常指按過去的計劃安排將在某個過去將來時間發(fā)生得事 態(tài)。例如:They were not to get away with it if they continued to violate the law.用作表示過去將來的安排,如果這個安排后來被取消了，沒有實現(xiàn)，那么用 uwas/were to+不定式完成體”表示，并可與表示現(xiàn)在、過去戒將來得時間狀語連用。此外， 其也可用作于表示以后不

7、可防止得要發(fā)生得事件。例如：They said goodbye, little knowing they were never to meet again.四、was/were about to + 不定式用半助動詞be about to的過去時形式也可使其表示過去將來。這種結(jié)構(gòu)通常 指最近的過去將來事態(tài)，而且在一定語境中通常指未曾實現(xiàn)的意圖：例如：Ne were about to start when it began to rain .五、某些動詞的過去進(jìn)行時可表示過去將來時come, go, leave, arrive, start等嚴(yán)格按照時間表發(fā)生的表起止的動詞可用過去 進(jìn)行時代替過

8、去將來時。例 1 :He said the train was leaving at six the next morning.他說火車第 二天早晨出發(fā)。例2:She told me she was coming to see me.她告訴我她要來 看我。六、特定場合的一般過去時可表示過去將來時條件狀語從句和時間狀語從句中須用一般過去時代替過去將來時。例 1:I didnt know when she would come, but when she came I would let you know.我不知道她什么時候來,但她來了我會告訴你。析:第一個when引導(dǎo)賓語從句，可使用將來時,第二個when引導(dǎo)時間狀語從句， 只能用一般過去時代替過去將來時。例 2:T didnt know
