過去將來時的用法
一、"would+動詞原形"表示過去將來時
"would+動詞原形"構(gòu)成過去將來時，常表示根據(jù)計劃或安排即將發(fā)生的事。
例1：He said he would come to see me.他說他要來看我。
例2：He told me he would go to Beijing.他告訴我他將去北京。
二、"was /were+going to+動詞原形"表示過去將來時
"was /were+going to+動詞原形"也可表示根據(jù)計劃或安排即將發(fā)生的事。
例1：She said she was going to start at once.她說她將立即出發(fā)。
例2：I was told that he was going to return home.他告訴我他準備要回家。
"was /were+going to+動詞原形"還可表示根據(jù)當時情況判斷有可能但不一定會發(fā)生某事。
例：It seemed as if it was going to rain.看來好像要下雨。
三、某些動詞的過去進行時可表示過去將來時
come,go,leave,arrive,start等嚴格按照時間表發(fā)生的表起止的動詞可用過去進行時代替過去將來時。
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。
四、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引導賓語從句，可使用將來時，第二個when引導時間狀語從句，只能用一般過去時代替過去將來時
過去將來時的結(jié)構(gòu)
1.同一般將來時不一樣，把系動詞be變?yōu)檫^去式，把will，shall變?yōu)檫^去式。
例句：I didnt know if he would come.
=I didnt know if he was going to come.
我不知道他是否會來。
She was sixty-six. In three years，she would be sixty-nine.
她66歲了。三年后，她是69歲。
She told us that she would not go with us，if it rained.
她告訴我們，如果下雨的話，她就不和我們一起去了。
I didnt know how to do it. What would be their ideas?
我不知道該怎么辦，他們會有什么想法呢?
2.過去將來時�？捎脕肀硎具^去習慣性的動作。此時，不管什么人稱，一律用would。
過去將來時有時可帶時間狀語
注意
1"was/were going to + 動詞原形"或"was/were +動詞不定式完成式"可表示未能實現(xiàn)的過去將來時間的動作。
2was/were about to do
"was/were about to do"表示說話的瞬間就會發(fā)生的動作。
3was/were on the point of doing
提示"be about to do" 和 "be on the point of doing"結(jié)構(gòu)一般不與表示將來的時間狀語連用，但后面可以接when引導的分句。
