第講高英語法虛語氣解和練習虛擬語氣英語中有三不同的語：陳述語，祈使語和虛擬語氣。虛擬語氣：虛擬語氣是由句中謂語動詞的特殊形式表現(xiàn)出來的，表示說話人所說的不是事實，而是一種假設、愿望、懷疑或推測。一．虛擬語氣表示假設，用在if非真實條件句中從句

主句與現(xiàn)在事實反與過去事實反與將來事實反

If主語+If主語+1.didIf主語+3.weredo

主語should/would/could/might主語+/could/might+have主語+should/would/could/might例：IfIyou,Iacceptadvice.Ifyoustudiedbefore,wouldhavetheIfittoIwouldat注意：1.錯綜時間虛擬語氣當從句主句所表示的行為所發(fā)生的時間不一致時的形式要根據(jù)它所表示的時間作出相應的調(diào)整。Ifyoujustyounow.Ifyou__________(study)hardyou_______(be)anow.2.省略if的虛擬條件句中，were，had（完成時態(tài)標志），should放在句首，（用于倒裝結構），if必須省略。(只裝從句，主句不改變Iyou(=IfIwerewouldnotdoit.1

did/were從句動作先（或用）從句動作在wish后

could/would/might+doIwishIabirdandIcouldflytheIwishIfilmstar此外，If句子HowI從句(要…就好了）IfonlyIflyingbird!=HowIwishIflying我要是一只飛鳥該多好啊！三.虛擬語氣用于表示懷疑或推測。在某些表示“命令建議、要求”等動詞，名詞以及形容詞存在的主語從句，賓語從句，表語從句，同位語從句的虛擬語氣結構為：（should）+do此類動詞憶口訣：一堅持(二命令三要求demand/require/request)四建議（suggest/propose/recommend2
