只有出现在单数第三人称主语之后，它才在形式上与陈述式was区别开来。were-型虚拟式的主要用法如下。
1.用于某些状语分句中
were-型虚拟式常用由if,if only ,as if,as though,though引导的条件状语和让步状语分句中，表示非真实的条件或让步。例如：
If I were you,I should wait till next week.
If it were to rain,the game would be put off.
If only I were not so nervous.(要是不那么紧张就好了。)
He spoke to me as if I were deaf.
He behaves as though he were better that us.
Though the whole world were against me,I would do what I consider as right.
2.用于某些名词性分句中
were-型虚拟式常用于出现在wish,would rather,suppose,imagine之后的that-分句中，表示一种臆想的(通常是不可能发生的)情况。例如：
I wish it were spring all the year round.
I'd rather I were not at the site of the accident.
Suppose the earth were flat.
Just imagine everyone were to give up smoking.
上述were-型虚拟式在第一、三人称单数主语之后可为was所取代。例如：
If it was to rain ,the game would be put off.
If only I was not so nervous!
I wish it was spring all the year round.
I'd rather I wasn't at the site of the accident.
但是，在if I were you 这一句中，通常只用were，不用was。另外在某些倒装结构中也只用were，不用was。例如：
Were I to do it(=If I were to do it,I should rely on you.
还有，在 as it were(作 so to speak解，即“宛如”、“好比”)结构中也只用were，不用was。例如：
He is my best friend,my second self,as it were.
如前所述，虚拟式在现代英语中已经不是一个重要的语法范畴，许多该用虚拟式的地方常为陈述式所取代。以上所述用should代替be,用was代替were就是一例，甚至还可根据语义意图干脆用现代时形式。例如：
I wish I were/was there.
He looksas if he were/was/is sick.
Imagine you are the salesman for Franco's product.
虚拟式/were-型虚拟式
were-型虚拟式只有一种形式，即不管主语是什么人称，动词一律用were,如 I were,you were,he were；如果动词为进行体或被动态，其助动词也一律用were,如 I were going,you were going,he were going；又如 I were sent, you were sent,he were sent,因此，were-型虚拟式只有出现在单数第三人称主语之后，它才在形式上与陈述式was区别开来。were-型虚拟式的主要用法如下。1.用于某些状语分句中
