在虚拟语气中，if引导的虚拟条件句是最为核心的，很多学生问我对应的三种时间结构是什么，今天我给各位同学进行了罗列。
课文：
‘A new play is coming to “The Globe” soon,’ I said. 'Will you be seeing it?’
‘No,’ she answered.
‘Will you be spending your holidays abroad this year?’ I asked.
‘No,’ she answered.
‘Will you be staying in England?’ I asked.
‘No,’ she answered.
In despair, I asked her whether she was enjoying her dinner.
‘Young man,’ she answered, ‘if you ate more and talked less, we would both enjoy our dinner.’
给大家附上三个例句：
If I were you, I would try it. 与现在事实相反
If he had realized that, he would have run away while there was still time. 与过去事实相反
If it were to/should rain tomorrow, the meeting would be put off. 与将来事实相反
其余案例：
I am not you, so I can’t make the decision.
If I were you, I could make the decision.（if虚拟条件句）
You make the arrangements, so it will save us a lot of trouble.
If you did not make the arrangements, it would not save us a lot of trouble.（if虚拟条件句）
I don’t know his phone number, so I won’t ring him up.
If I knew his phone number, I would ring him up. （if虚拟条件句）
