能夠在語境中判斷虛擬語氣的種類及是否需要虛擬

在寫作中使用

虛擬語氣的分類

①表要求，建議，命令等詞匯后所加從句中的虛擬

②情態(tài)動(dòng)詞的一些表達(dá)虛擬的用法

③跟在wish,asif/though,ifonly及wouldrather后的虛擬

④If所引導(dǎo)的條件狀語從句及主句中涉及的各類虛擬

Without,butfor,otherwise等引導(dǎo)的虛擬

表要求，建議，命令等詞匯后所加從句中的虛擬

虛擬形式：that+S+(should)do/bedone

要求：ask,require,request,demand

建議：suggest,advice,recommend,propose

命令：order,command

其他：insist,desire,urge

這類動(dòng)詞后面所加從句多為表達(dá)說話者對(duì)他人的要求，建議，命令，愿望等，所說的事件均未發(fā)生（所以應(yīng)特別注意suggest意為表明或者暗示時(shí)，及insist表達(dá)對(duì)已發(fā)生事件看法時(shí)，均不需要采用此類虛擬。

Herpalefacesuggestedthatshewasill.

Heinsistedthathegottheinformationfromareliablesource.

根據(jù)提示填空

①Isuggestthatshe_______________(take)thecourse.

②Hedemandedthatallthework________________(do)byFriday.

③Heurgedthatwe_____________(delete)thephotosastheywerespreadillegally.

④Muminsistedourhands__________________(wash)beforeeatingthemeal.

shouldtake

shouldbedone

shoulddelete

shouldbewashed

觀察以下句子，得出你的結(jié)論：

①Itismysuggestionthatsheshouldtakethecourse.

②Itissuggestedthatsheshouldtakethecourse.

③ItisdemandedthatalltheworkshouldbedonebyFriday.

④Itisinsistedthatweshouldwashourhandsbeforemeal.

你的結(jié)論：以上動(dòng)詞的各種詞性變化（名詞，形容詞）后加從句_______________.

再認(rèn)真觀察以上四個(gè)句子，它們是

that+S+(should)do/bedone

Itis/was+n/adj.+從句的結(jié)構(gòu)

Itisapitythatheshouldbesostupid.

Itisnecessarythatheshouldattendthemeeting.

這個(gè)句式中的一個(gè)特例是“該是做……的時(shí)候了”Itis(about/high)timethatsb

Itistimethatyoushouldgetdowntostudy.

Itistimethatyougotdowntostudy.

Itistimethatyou______(go)tobed.

Itis/was+n/adj.+從句的結(jié)構(gòu)

that+S+(should)do/bedone

went

跟在wish,asif/though,ifonly及wouldrather后從句的虛擬

這類虛擬中，從句謂語的時(shí)態(tài)要根據(jù)對(duì)所虛擬事件的時(shí)間進(jìn)行改變，原則上是往后退一個(gè)時(shí)間的時(shí)態(tài)

1.對(duì)將來的虛擬變成過去將來時(shí)，如

willwould，cancould

2.對(duì)現(xiàn)在的虛擬，變成過去式，如

do/doesdid，is/am/arewere

3.對(duì)過去的虛擬，變成過去完成時(shí)，如

didhaddone

（注意：wouldrather所加從句對(duì)現(xiàn)在和將來的虛擬，統(tǒng)一用過去式，對(duì)過去的虛擬用過去完成時(shí)）

①HowIwishthatIcouldattendyourwedding.ItisapitythatIshouldbeonameetingthen.

②IwishIwerenothere.Lookhowridiculoustheyare!

If所引導(dǎo)的條件狀語從句及主句中涉及的各類虛擬

真實(shí)條件句

Ifitdoesn'traintomorrow,wewillhaveapicnicinthepark.

在if引導(dǎo)的條件句表有可能實(shí)現(xiàn)的將來時(shí)，從句用________來表將來。

換句話說，一般情況下，if引導(dǎo)的條件句中，從句不會(huì)出現(xiàn)will（表意愿除外）。

現(xiàn)在時(shí)

非真實(shí)的條件句

Ifitdoesn'traintomorrow,wewillhaveapicnicinthepark.

Ifitdidn'traintomorrow,

wewouldhaveapicnicinthepark.

If引導(dǎo)的從句主句（一定要出現(xiàn)would/could/might等情態(tài)動(dòng)詞的過去式）

謂語動(dòng)詞用_________________1.Ifitshould/weretoraintomorrow,Ifitrainedtomorrow,2.IfI___________/____________/_______________(notstay)uptonight,謂語動(dòng)詞用___________________________

1.thesportsmeetingwouldbeputoff.

didn’tstay

weren’tstay

shouldn’tstay

wouldn’tfinish

wouldbe

wereto/did/shoulddo

would/could/mightdo

If引導(dǎo)的從句主句（一定要出現(xiàn)would/could/might等情態(tài)動(dòng)詞的過去式）

謂語動(dòng)詞改為______/_did_①IfIwereyou,②IfI_________(benot)here,謂語動(dòng)詞用would(could/might…)do

①Iwouldaccepthisinvitation.

②Iwouldnotseethiswonderfulshow.

weren’t

were

If引導(dǎo)的從句主句（一定要出現(xiàn)would/could/might等情態(tài)動(dòng)詞的過去式）

謂語動(dòng)詞改為haddone①Ifyouhadlistenedtoyourteacher,②Ifyou__________(work)harder,謂語動(dòng)詞用would(could/might…)+__________

①youwouldhavepassedtheexam.

②you________________(willget)bettermarks.

wouldhavegot

hadworked

havedone

If引導(dǎo)的從句主句（一定要出現(xiàn)would/could/might等情態(tài)動(dòng)詞的過去式）

①Ifyouhadlistenedtothedoctor,(從句是對(duì)過去的虛擬，用___________)②IfIwereyou,(從句是對(duì)現(xiàn)在的虛擬，用過去式)③Ifyou______________(study)harder,④IfI___________(know)itwouldbesoboring,IfI______(be)you,①youwouldn'tbeinthehospitalnow.(主句是對(duì)現(xiàn)在的虛擬，用_____________________________)

②Iwouldhavebeatenhimup.(主句是對(duì)過去的虛擬，用wouldhavedone)

③you___________________(besitting)inaofficecomfortablynow.

④I_____________(notbe)here.

⑤I___________________(beat)himupyesterday.

hadn’tstudied

hadknown

were

wouldn’tbesitting

wouldn’tbe

haddone

would/could/mightbe/do

wouldhavebeaten

虛擬的省略倒裝省略if，將should/were/had前置到句首，其余不做變化

Eg:IfIwereyou,Iwouldaccepthisinvitation.

WereIyou,Iwouldaccepthisinvitation.

IfIshouldspendsomuchmoney,Iwouldnotattendthecourse.

ShouldIspendsomuchmoney,Iwouldnotattendthecourse.

IfIhadlistenedtohim,Iwouldhaveavoidedthemistakes.

HadIlistenedtohim,Iwouldhaveavoidedthemistakes.

這幾個(gè)短語其實(shí)都是if引導(dǎo)的從句的變形，只不過

if引導(dǎo)的是從句，

without及butfor是介詞，

otherwise/or前則加一個(gè)表事實(shí)的句子，

但是緊隨這三個(gè)單詞或短語后面的句子沿用的均是上一種情況中主句的虛擬形式，即

虛擬條件句的衍生

Without,butfor,otherwise/or等引導(dǎo)的虛擬

對(duì)過去的虛擬，用would/could/might/shouldhavedone

對(duì)現(xiàn)在和將來的虛擬，用would/could/might/shoulddo

Ifithadn’tbeenyourhelp,Icouldn'thavepassedtheexam.

③Butforhisteachers’help,he____________________(notget)suchgoodmarks.

虛擬中需要注意的真實(shí)情況

①Hedidn'tdohishomework,orhismumwouldn'thavebeensoangry.

②Butfor
