1、虛擬語氣三大板塊含有條件狀語從句的復合句名詞性從句賓語從句S.+wish(wouldrather)+賓語從句S.+suggest(demand…)+賓語從句主語從句Itis+adj./p.p/n.+that+S+(should)+do表語從句S.+isthat+s.+(should)+do同位語從句S.+that+s.+(should)+do定語從句Itishigh/abouttimethat+s.+shoulddosth.(didsth)兩種形式1.時態(tài)后退型用一般過去表示現(xiàn)在用過去完成表示過
2、去用過去將來表示將來2.should+動詞原形型語法專題十三:虛擬語氣與情態(tài)動詞情態(tài)動詞和虛擬語氣是高考重要考點,《2017年普通高等學校招生全國統(tǒng)一考試大綱》附錄語法項目表中列出了虛擬語氣以及情態(tài)動詞。2015年高考全國卷Ⅰ第79題(短文改錯)考查了情態(tài)動詞must后面接動詞原形。2016年高考全國卷Ⅰ沒有考查情態(tài)動詞與虛擬語氣。2017年高考全國卷Ⅰ沒有考查情態(tài)動詞與虛擬語氣。知識框架77一.含有條件狀語從句的復合句(以do為例;S=主語)時間條件狀語從句主句現(xiàn)在If+S+did(were)
3、S+would/should/could/might+do過去If+S+haddoneS+would/should/could/might+havedone將來did(were)If+SshoulddoweretodoS+would/should/could/might+do例如:①IfIwereyou,Iwouldapplyforthejob.②IfIhadthemoney,Iwouldbuyit.③IfIweregivenanotherchance,Iwoulddoitbetter.④IfI

5、移至主語之前構成倒裝句。例如:①WereIyou,Iwouldapplyforthejob.②HadItakenyouradvice,Iwouldhavemadegreatprogress.③Shoulditraintomorrow,Iwouldstayathomeallday.二、錯綜時間的條件句虛擬條件句中的主句和從句涉及的動作發(fā)生的時間不一致,這時主句和從句的謂語形式應按照各自動作發(fā)生的實際時間來表達。例如:①Ifyouhadn'twatchedTVyesterday,youwouldn'
6、tbesosleepynow.(從句yesterday說明過去,主句now說明現(xiàn)在)②Iftheyhadlefthomeearlythismorning,theywouldarriveinhalfanhour.(從句說明過去,主句說明將來。)③Ifyouhesitatedthismoment,youmightsufferinthefuture.(從句說明現(xiàn)在,主句說明將來)三、含蓄條件句非真實條件句中的條件從句有時不表達出來,只暗含在上下文中,這種句子叫做含蓄條件句。含蓄條件句有三種情況:1.條
7、件暗含在單詞短語中:常見介詞有with假如有,without假如沒有,butfor要不是因為;連詞有or/otherwise(前句用陳述語氣,后句用虛擬);but(前句為虛擬,后句陳述)例如:①Hewouldnotgetsucharesultwithoutyourhelp.(條件暗含在介詞短語withoutyourhelp=ifyouhadn’thelpedhim中)②Butforyou,Icouldnotberecoveredsosoon.(條件暗含在Butforyou=Ifyouhadn’t
8、helpedme中)77③Hemusthavebeenthere,orhenevercouldknowtheplacesowell.(暗含條件是連詞or;后句為虛擬)④Iwouldhavebeentoyourplace,butIwasreallytoobusy.=Iwasreallytoobusy,or/otherwiseIwouldhavebeentoyourplace.⑤Shewasill,otherwiseshewouldhavebeenpresentatthemeeting.(條件通過連
