假设语气总共可以假设过去现在跟未来
然后假设现在又有两种说法(现在式跟过去式)
而其中又有分主动跟被动
If I have the money, I will buy a car. 如果我(现在)有钱的话我就会马上买一部车
(I我现在是"可能"有钱的可能会是家人金援之类的为可能发生的事物)
If I had the money, I would buy a car. 如果我(现在)有钱的话我就会买一部车
(我现在是"不可能"有钱的所以我也不可能买车所以用would buy a car)
ps. 如果是假设现在100%不可能发生的则是不分人称用were 拿Beyonce的歌 If I were a boy来举例子就是他是女的他永远不可能变成男的
If I had had the money then, I would have bought a car. 如果我那时候(过去)有钱的话我就会(已经)买了一部车了
(我过去那时候不可能有钱所以我也绝对没有已经(过去的未来但是又是在讲这句话为基准点的之前也就是说比过去还要靠近现在一点可是还是算过去)买车)
If I had had the money then, I would buy a car.如果我那时候(过去)有钱的话我就会(讲这句话为基准的未来)买一部车了
(我过去那时候不可能有钱所以我未来也不可能有买车的机会不过这句话比较不常用因为过去没钱跟未来买车有何关联)
If I had saved some money up, I would be able to buy a car.
If I had saved some money up, I would have been able to buy a car.
这样因为有存钱所以未来可以买车的句子这两句话就可以只是表达的时间还是不太一样
If I were to have the money, I would buy a car. 如果我(未来)有钱的话我就会买一部车
(可是事实是我没有什么工作未来也没有翻身我没有在未来可以拿到钱的机会)
比较常用的假设就这几个
然后你在原文问说所以现在有钱囉其实是不一定的
过去没有钱也不代表现在的情况会改变会变成有钱
这是比较逻辑的问题跟英文文法就没太大的关联了
