現(xiàn)在：過去：過去時(shí)過去完成時(shí)Shelovesthebabyasifitwereherownson.Irememberthewholethingasifithadhappenedyesterday.后接虛擬語氣，表示不可能或不真實(shí)的事或情形。4.It’s(about/high)time+thatshould+V.過去時(shí)我們該去睡覺了。It’stimethatwewenttobed.It’stimethatweshouldgotobed.

5.表示要求，命令，建議的虛擬語氣。這些動(dòng)詞后面的賓語從句要使用虛擬語氣用法。即從句中的動(dòng)詞使用should+動(dòng)詞原形，或者將should省略。一堅(jiān)持二命令三建議四要求insistorder,commandadvise,suggest,proposedemand,require,request,desire

注意：以上動(dòng)詞相應(yīng)的名詞構(gòu)成的名詞性從句包括主語從句，表語從句和同位語也要使用虛擬語氣。從句中的動(dòng)詞形式一樣。

order,advice,suggestion,proposal,demand,request,desire

注意：insist表示“堅(jiān)持說”時(shí),后面從句不用虛擬語氣.如:Sheinsistedthathehadstolenherbike.Suggest表示“暗示”,“表明”時(shí),后面從句中不用虛擬.如:Herpalefacesuggeststhatsheisill.

IftheUnitedStateshadbuiltmorehomesforpoorpeoplein1955,thehousingproblemsnowinsomepartsofthiscountry______soserious.A.wouldn’tbeB.willnothavebeenC.wouldn’thavebeenD.wouldhavenotbeen√Ifyouhadfollowedmyadvice,youwouldbebetternow.Ifyouhadstudiedhardbefore,youwouldbeacollegestudentnow,andyouwouldgraduatefromacollegeinfouryears’time.②假設(shè)條件虛擬倒裝。條件從句中有should，were，had三個(gè)助動(dòng)詞,可以把if省略，并將這三個(gè)詞提至句首。
