虛擬語氣知識(shí)點(diǎn)講解和寫作運(yùn)用講義-高三英語寫作專項(xiàng)

虛擬語氣知識(shí)點(diǎn)講解和寫作運(yùn)用01個(gè)人意愿1.

在常見動(dòng)詞:一個(gè)堅(jiān)持，兩個(gè)命令，三個(gè)建議，四個(gè)要求。1.insist

2.order,command

3.advise,suggest,recommend

4.demand,require,request,desire這些動(dòng)詞后面的賓語從句要使用虛擬語氣。即從句中的動(dòng)詞使用should+

動(dòng)詞原形，或者將should省略。a.

I

demanded

thathe

be

hereassoonaspossible.b.

Itis

required

thatmiddleschoolstudents

(should)take

onehourexerciseeveryday.c.

His

suggestion

isthatwe

persuade

hertostayherefirst.注意:insist

表示“堅(jiān)持認(rèn)為”講時(shí)不用虛擬語氣；

Heinsistedthathewasinnocent.suggest

做“表明暗示”時(shí)不用虛擬語氣；Whathesaidsuggestedthathewasafraud.

2.

It’s(about/high)time+that

該是做某事的時(shí)候到了從句謂語：過去時(shí)

(要是...該多好）+

wish從句的謂語分三種情況討論：(1)表示對(duì)現(xiàn)在情況的虛擬,從句動(dòng)詞用過去式（be動(dòng)詞一般用were）(2)表示對(duì)過去情況的虛擬,

從句動(dòng)詞常用“had＋過去分詞”。（過去完成時(shí)）(3)表示對(duì)將來的主觀愿望,

從句動(dòng)詞形式為“would＋動(dòng)詞原形”。（過去將來時(shí)）a.

虛擬過去：haddonea.

2)混合條件句主句與從句的動(dòng)作發(fā)生在不同的時(shí)間，這時(shí)主、從句謂語動(dòng)詞的虛擬語氣形式因時(shí)間不同而不同，這叫做混合條件句。a.

Ifyou

hadasked

himyesterday,you

wouldknow

whattodo

now.(從句與過去事實(shí)相反，主句與現(xiàn)在事實(shí)相反。)b.

Ifit

hadrained

lastnight(過去),it

wouldbe

verycoldtoday

(現(xiàn)在).3)虛擬條件句的倒裝虛擬條件句的從句部分如果含有were,should,

或had,

可將if省略，再把were,should或had

移到從句句首，實(shí)行倒裝。a.

Were

theyherenow,they

couldhelp

us.=

Iftheywereherenow,theycouldhelpus.b.

Had

you

come

earlier,you

wouldhavemet

him.=Ifyouhadcomeearlier,youwouldhavemethim.c.

Should

it

rain,

thecrops

wouldbesaved.=Wereittorain,thecropswouldbesaved.

注意:在虛擬語氣的從句中，動(dòng)詞'be'的過去時(shí)態(tài)一律用"were"，不用was，

即在從句中be用were代替。a.

IfI

were

you,I

wouldgo

tolookforhim.

如果我是你，就會(huì)去找他。b.

Ifhe

were

here,everything

wouldbe

allright.注意：if的從句直接可以簡(jiǎn)化成without/butfor+

名詞（短語）a.

Withoutsunlight,people’slife

wouldbe

differentfromtoday.b.

Butforyourhelp,I

wouldn’thavefinished

thework.
