关于虚拟条件句中 was 与 were 的用法问题，下面是一个小归纳，希望对这位网友有所帮助：

▲在虚拟条件句中，若主语是I / he / she / it 等单数形式之后，其后的动词 be 可用 were代替 was。两者在意义上没有区别，但是 were 更为正式，特别是在陈述心存怀疑的事情时：

If I were / was any richer, I’d buy ayacht. 如果我有点儿钱，我就买艘游艇。

If I were / was better qualified, I’d applyfor the job. 如果我的条件好一些，我就申请那份工作了。

然而在陈述纯粹想象的事情时，were 更为常用。如：

If I were a bird, I could fly to you. 如果我是只鸟，我就会飞到你身旁。

If I were a man they would have given methe job. 我要是男的，这份工作就准给我了。

▲在 If I wereyou / If I were in your position 这类表达，最好不用 was。这些说法经常用于提出建议。如：

If I were you, I would go. 我要是你，我就会去。

If I were in your position, I would accepttheir offer. 如果我处于你的地位，我会接受他们的条件。

此用法用于除第二人称之外的人称也是如此。如：

If I were Jane / in Jane’s position, I’dwalk out on him. 如果我是珍妮，我就会离弃他。

▲在 If it werenot for / Were it not for 这类结构中可以用 was 代替 were，但以用 were 更为常用。如：

If it weren’t / wasn’t for your help, Iwould still be homeless. 若非你的帮助，我仍会无家可归。

If it wasn’t / weren’t for his wife’s moneyhe’d never be a director. 如果不是他妻子的钱，他决不可能成为董事。

但若将 were 移至主语前而省略连词 if 时，则只用 were 而不用 was。如：

Were I Tom I would refuse. 如果我是汤姆，我会拒绝的。

Were it not for your help, I would still behomeless. 若非你的帮助，我仍会无家可归。
