等我一天我來整理一下
好啦,你看看吧
do/be(為例） 虛擬語氣主句
條件狀語從句
與現(xiàn)在事實相反 did/werewould(could,might)do/be
與過去事實相反 had done/
had been would(could,might)have/been
與將來事實相反did/werewould(could,might)do/be
were to do/be
should de/be
舉兩個例子吧：
1、我要是你,就采納他的意見
If I were in your position,I would take his advice.
2、如果我聽從了醫(yī)生的建議,我的病早該好啦
If I had followed the doctor's advice, I would have been all right.
練習一道吧：
--If he_____,he_____that food.
--luckily he was sent to the hospital immediately.
A.was warned;would not take
