一般過去將來時可用來表示非真實的動作或狀態(tài)：If I had a chance to study abroad, I would study at University of Cambridge.(如果我有機會出國學(xué)習(xí)的話，我就會去劍橋大學(xué)。)
其他表達(dá)法：
1. was/were going to + 動詞原形：He said that he was going to live in the country when he retired.(他說他退休后要住在農(nóng)村。)
2. was/were + 動詞-ing形式：Nobody knew whether the guests were coming.(沒人知道客人們是否要來。)
3. was/were + 動詞不定式：She said she was to clean the classroom after school.(她說她放學(xué)后要打掃教室。)
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。
例如：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。)
2. "was/were about to do"表示說話的瞬間就會發(fā)生的動作。
例如：I felt something terrible was about to happen.(我覺得有可怕的事要發(fā)生了。)
3. was/were on the point of doing
例如：I’m glad you have come. I was on the point of calling you, but you’ve saved me the trouble now.(很高興你來了。我正準(zhǔn)備給你打電話，現(xiàn)在你省去我這個麻煩了。)
4. "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(dǎo)的分句。
例如：I was about to start when it suddenly began to rain.(我正要動身天突然下雨了。)
5. 過去將來時常可用來表示過去習(xí)慣性的動作。此時，不管什么人稱，一律用would。
例如：This door wouldn’t open.(這扇門老是打不開。 )
