wish后的賓語從句的虛擬語式

要表示與現(xiàn)在事實(shí)相反的愿望，從句謂語一般過去時(shí)或過去進(jìn)行時(shí)，表示與過去相反的愿望，從句謂語用過去完成時(shí)或would / could+have +過去分詞，表示將來沒有把握或不太可能實(shí)現(xiàn)的愿望，用would (could)＋動(dòng)詞原形。如：

I wish I were not so busy. 但愿我不那樣忙碌。

I wish I could be of some use. 我希望我能有什么用處。

I wish you would be more respectful to your father. 我希望你對你父親更尊敬些。

注：從句的時(shí)態(tài)只與從句所指的時(shí)間有關(guān)，而與 wish 的時(shí)態(tài)無關(guān)，比較：

I wish I were rich. 要是我現(xiàn)在有錢就好了。

I wish I had been rich. 要是那時(shí)我有錢就好了。

I wished I were rich. 當(dāng)時(shí)我后悔自己沒有錢。

I wished I had been rich. 當(dāng)時(shí)我后悔自己曾經(jīng)沒有錢。
