一般過(guò)去將來(lái)時(shí)
形式：would+動(dòng)詞原形和was/were going to+動(dòng)詞原形
用于描述過(guò)去某時(shí)間里你對(duì)于未來(lái)的想法和猜測(cè)。

虛擬語(yǔ)氣（此處我們談?wù)搶?duì)現(xiàn)在和將來(lái)情況的虛擬）
形式：would/should/might/could+動(dòng)詞原形
用于描述不能實(shí)現(xiàn)或者純粹是家鄉(xiāng)的情況。

例句對(duì)比：
（1）
I was sure that I would work in a small city when I was a child. 在我很小的時(shí)候我就覺(jué)得我會(huì)在一個(gè)小城市工作。
If I were you, I would choose to work in a small city. 如果我是你，我會(huì)選擇在小城市工作。（事實(shí)上我不是你）

（2）
You told me that you would talk with your parents. 你告訴我你會(huì)和父母談?wù)劦摹?br> If you talked with your parents, something wouldn't happen. 如果你和父母談過(guò)了，有些事就不會(huì)發(fā)生了。（你沒(méi)和父母談過(guò)）

（3）
She hoped that when Nixon told it to me the next morning I would not give him a hard time. 她希望第二天上午尼克松同我談起這件事時(shí)，我不要使他難堪。
If she told me about this, I wouldn't give Nixon a hard time. 如果她告訴我這些，我就不會(huì)讓尼克松難堪了。（她沒(méi)告訴我這些事）

是不是感覺(jué)二者很相似？其實(shí)虛擬句和過(guò)去將來(lái)時(shí)最大的不同便是虛擬句是純粹的假想，不會(huì)發(fā)生的事情。而過(guò)去將來(lái)時(shí)則是計(jì)劃會(huì)發(fā)生的事。
