虚拟语气用于表达假设、愿望、建议等虚拟情况。以下是一些常见的虚拟语气句子：

It is time （that）…

It is （high） time that + S + V（虚拟语气）

例：It is high time that you children went to bed.

wish+宾语从句

wish + 宾语从句的谓语动词用 had done（与过去事实相反）

wish + 宾语从句的谓语动词用 would / could / should / might do（与将来事实相反）

例：I wish I had a ticket to the Christmas Party.

例：I wish I had not said those stupid words to that girl.

if条件句

纯条件的虚拟语气——用现在时

If he is there, I will beat him.

与现在事实相反的虚拟语气——用过去时

If he were here, I would beat him. （But he is not here.）

与过去事实相反的虚拟语气——用过去完成时

If he had been here, I would have beaten him. （But he was not here.）

与将来状况相反的虚拟语气——if从句要用助动词should，译成“万一”，主句则用过去时或现在时助动词

If he should be here, I would/will beat him.

表示对将来的假设

If + were/did/（动词过去式）/should/were to do， 主语 + would/might/should/could + do

例：If we were to panic, we would not be able to give proper first aid.

条件暗含在上下文中
