虛擬語態(tài)的形式
1、對現(xiàn)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(xiàn)在的虛擬相同，但對現(xiàn)在的虛擬不用were to.
要區(qū)別對將來的虛擬和對現(xiàn)在的虛擬``一般句子里面都有時間標(biāo)志``)
(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.)
(至于If ..had been done...would have done
前面的been只是因為是被動語態(tài)```所以要看句子的具體意思````)
固定句型的補充。
要用虛擬語態(tài)的句子:
I would rather I could......(I would rather she could not come here)
if only..(但愿....)
A:I will go to Korea next month.B:If only I could go with you
虛擬語態(tài)表示動作或狀態(tài)不是客觀存在的事實，而是說話人的主觀愿望，假設(shè)，推測，命令，建議，要求等。
虛擬語態(tài)的基本結(jié)構(gòu)
(1). 與現(xiàn)在事實相反的假設(shè)：一般過去時(be用were)，主句結(jié)構(gòu){ should(would)等+動詞原型}
例如：If they were here ,they would help you.如果他們在這，會幫助你的。
(2). 與過去事實相反的假設(shè)：過去完成時主句結(jié)構(gòu)：{should(would)等+have+過去分詞}
例如：If he had come yesterday,Ishould(would)have told him about it.如果他昨天來的話，我會把這件事告訴他的。
(3). 表示對將來不大發(fā)生的事的假想。一般過去時，were+不定式，should+動詞原形;主句結(jié)構(gòu)：{should(would)+動詞原形。
例如：If you succeeded ,everything would be all right.如果你將來成功了一切都會好的。
