答案
時間 if條件句（謂語動詞形式） 主句（謂語動詞形式）
現(xiàn)在 過去式/be(were) would/should…do
過去 had done would/should…h(huán)ave done
將來 過去式/should do/were to do would/should do
省略if 把had、were、should等提到句首，用倒裝語序
一、 復習：
bbaab
二、 自主學習：
if 從句與過去事實相反，故用had done, 主句與現(xiàn)在事實相反，故用would be.
ab
三、 虛擬語氣的其他用法：
在賓語從句中的應用。
表示命令、建議、要求等的動詞+賓語從句，從句用虛擬語氣。（should ）+ do 的形式。常見的詞：suggest，advise，recommend，propose；order，command；require，request，demand；insist。
