　　虛擬語態的形式

　　1、對現在的虛擬：***直接用動詞的過去時....***

　　if I did /were.... I would.......

　　2、對將來的虛擬：if ..were to..I would....= if ..did...I would....

　　***此項與對現在的虛擬相同，但對現在的虛擬不用were to.

　　要區別對將來的虛擬和對現在的虛擬``一般句子裡面都有時間標誌``***

　　***If it were to rain tomorrow,we would not go out.

　　=If it rained tomorow,we would not go out.***

　　3、對過去的虛擬 If I had done....I would have done....

　　***If I had known the answer, I would have told you.***

　　***至於If ..had been done...would have done

　　前面的been只是因為是被動語態```所以要看句子的具體意思````***

　　固定句型的補充。

　　要用虛擬語態的句子:

　　I would rather I could......***I would rather she could not come here***

　　if only..***但願....***

　　A:I will go to Korea next month.B:If only I could go with you

　　虛擬語態表示動作或狀態不是客觀存在的事實，而是說話人的主觀願望，假設，推測，命令，建議，要求等。
