wish后賓語從句用虛擬語氣,其謂語部分有時態(tài)變化：表示對現(xiàn)在情況珠虛擬時,動詞用一般過去時(如did)；對過去的情況進行虛擬時,動詞用“過去完成時(如had done)或情態(tài)動詞的過去時 + 動詞的現(xiàn)在完成時(如could have done)”形式；表示情況的虛擬時,用“情態(tài)動詞的過去時形式 + 動詞原形(如might do).”
I wish I had been to the concert last night.
I wish he would forgive me.
I wish I would remember all the English words in a week.
同例：在as if /as though引導(dǎo)的狀語從句中和以 if only引起的感嘆句中,謂語動詞與wish引導(dǎo)的賓語從句中的虛擬形式相同.例：
He talked as if he had known Tom for a long time.
He talks as if he were the boss.他說起話來就像他是老板.
