句式大盤點(diǎn)

It

既是代詞，也是引導(dǎo)詞（語法亦叫功能詞），是最簡(jiǎn)單也是用法最復(fù)雜的一個(gè)詞。作為代詞，it主要用于指代前文提及的某種事物、某種情況，甚至還可以指性別不明確的人；也可以指時(shí)間、日期、地點(diǎn)、距離、天氣、溫度、環(huán)境等。作為引導(dǎo)詞，it可以用作形式主語、形式賓語以及引導(dǎo)強(qiáng)調(diào)句型等。關(guān)于it作為代詞的用法，大家都已經(jīng)十分熟悉。本文不再贅述，而主要對(duì)it作為功能詞的用法，做一歸納和總結(jié)。

1.It

is

necessary

(for

sb.)

to

do

sth.

句式在該句式中，it是形式主語，動(dòng)詞不定式是真正主語，不定式的邏輯主語用forsb.。句式中的形容詞通常表示不定式的重要性、必要性、難易程度等基本情況。如

important,necessary,natural,easy,safe,common,normal,hard,difficult,dangerous,unusual,rare,impossible,pleasant等

。例如：Itisveryimportantforustotakepartinphysicaltrainingoutofclass.Itistoodifficultforathree-year-oldchildtoanswersuchaquestion.不可以說：*Weareveryimportanttotakepartinphysicaltrainingoutofclass.*Athree-year-oldchildistoodifficulttoanswersuchaquestion.2.

It

is

kind

(of

sb.)

to

do

sth.

句式該句式與上述句式十分相似，形容詞往往表示不定式邏輯主語的品質(zhì)或特征屬性，所以用ofsb.,

不用forsb.

常見的這類形容詞有：good,bad,brave,careless,clever,cruel,foolish,

honest,horrible,kind,lazy,modest,naughty,nice,polite,rude,silly,stupid,wise,wrong,等。例如：It

isvery

kind

of

you

to

helpmeoutoftrouble.

Itwasbraveofhimtojumpintotherivertorescuethedrowningboy.上述兩句可以轉(zhuǎn)換為：Youareverykindtohelpmeoutoftrouble.Hewasbravetojumpintotherivertorescuethedrowningboy.3.

It

is

no

good

(use,pleasure,fun)

doing

sth.

句式該句式中，it是形式主語，表語部分是否定意義，形容詞往往表示“益處，用處，樂趣”等含義，真正主語一般用動(dòng)名詞形式。例如：It

is

no

good

learning

English

without

speaking

English.

Itisnofunclimbingmountainsonrainingdays.4.

It

is

clear

(apparent,obvious,true,probable,likely,possible,impossible,certain…)that句式該句式中，it

是形式主語，真正的主語是that

引導(dǎo)的主語從句，這是it引導(dǎo)主語從句最常見的一種結(jié)構(gòu)。It

is

very

clear

that

he’s

round

and

tall

like

a

tree.

=

That

he’s

round

and

tall

like

a

tree

is

very

clear.

Itisverylikelythathewillnotconsent.=Thathewillnotconsentislikely.5.

It

is

important

(necessary,right,strange,natural...)

that句式該句式跟上一個(gè)同屬一種類型。由于主句中的形容詞性質(zhì)不一樣，它們表示事物的重要性、必要性、正確與否以及帶有“出乎意料的語氣”，所以，that

從句中要用虛擬語氣（should

+

動(dòng)詞原形）。建議讓學(xué)生記住用于該句型的形容詞。例如：It

is

important

that

we

should

learn

English

well.

It

is

necessary

that

he

should

remember

these

languagerules.6.

It

is

said

(reported,believed,

agreed,announced,hoped,expected,thought...)

that句式該句型中的it

仍是形式主語，真正主語是that

引導(dǎo)的主語從句。該結(jié)構(gòu)常譯為“據(jù)說（據(jù)報(bào)道，人們相信……）”。

It

is

said

that

he

has

gone

to

LosAngles.

It

is

reported

that

another

earth

satellite

has

been

sent

into

orbit.7.

It

is

suggested

(ordered,

recommended,required...)

that句式該句式跟上一個(gè)同屬一種類型。主句中的過去分詞表示請(qǐng)求，建議，命令等含義，that后的從句要用虛擬語氣（should

+

動(dòng)詞原形），should

可以省略。常譯為“據(jù)建議（有命令說……）It

is

suggested

that

the

meeting

(

should

)

be

put

offtillnextFriday.

It

was

ordered

that

thesoldiers(should)

arrive

there

in

two

hours.

8.

It

is

a

pity

(a

shame,afact,awonder,

apleasure...)

that句式該句式中，如果表示出乎意料，常譯為“竟然”，that從句也用虛擬語氣（should

+

動(dòng)詞原形）。若沒有這種意義時(shí)，則不用虛擬語氣。It

is

a

pity

that

such

a

thing

shouldhappen

in

your

class.

這種事竟然發(fā)生在你們班上，真是遺憾！

It

is

a

pity

that

he

is

ill.

他生病了，真遺憾！

9.

It

is

time

(about

time,high

time)

that句式該句式中，that

后的從句用虛擬語氣：可以使用一般過去時(shí)態(tài),

有時(shí)也用should

+

動(dòng)詞原形。常譯為“該是…的時(shí)候了”，意味著時(shí)間有些晚了。It

is

time

that

children

went

to

bed.

Itishightimewebegantoworkonthepainting.It

is

abouttime

that

weshouldhaveourlunch.10.

It

is

the

first

(second...)

time

that句式該句式要跟上一個(gè)句型區(qū)別開來。該句型中的

that

從句不用虛擬語氣，而是用完成時(shí)態(tài)。主句的謂語動(dòng)詞如果是一般現(xiàn)在時(shí)，后面從句就用現(xiàn)在完成時(shí)；如果是一般過去時(shí)，后面從句則用過去完成時(shí)。該結(jié)構(gòu)中

that

可以省去；it有時(shí)用

this

替換。常譯為“這是第一（二）次……”。

It

is

the

first

time

I

have

been

totheGreatWall.

Itwasthethirdtimehehadbrokentherules.11.

It

is...since

句式該句式主要用于表達(dá)非延續(xù)動(dòng)詞和一段時(shí)間連用的問題。Itis

之后是一段時(shí)間，時(shí)態(tài)是一般現(xiàn)在時(shí)（有時(shí)可以是現(xiàn)在完成時(shí)），since

引導(dǎo)的從句通常是一般過去時(shí)態(tài)，而且是瞬間動(dòng)詞。It

is

five

years

since

myolderbrotherjoinedthearmy.

Ithasbeenalongtimesincewedepartedlasttime.12.

It

is

...when句式該句式中的

when

引導(dǎo)一個(gè)時(shí)間狀語從句，主句中的

it

是代詞指時(shí)間，表語由具體的時(shí)間充當(dāng)。常譯為“當(dāng)……的時(shí)候，時(shí)間是……”。

It

was

5

o’clock

when

he

Itwasmidnightwhenhereturnedhome13.

It

be+一段時(shí)間+

before句式該句型中，it

是代詞指時(shí)間,

主句中的時(shí)態(tài)通常是將來時(shí)或過去時(shí)兩種時(shí)態(tài)。主句中的表語多是long,not

long,3

days,2

weeks

等表示一段時(shí)間。常譯為“……之后就……”。

It

was

3

days

before

he

camebackhome.

三天后他回了家。（直譯：在他回家之前時(shí)間是三天。）It

will

be

not

long

before

he

finishes

his

job.

不久后他就會(huì)完成工作。（直譯：在他完成工作之前，時(shí)間是不會(huì)長(zhǎng)的。）【句子分析】ItwillbehalfayearbeforeIcomeback.

在我回來之前，時(shí)間將有半年。意為“我半年之后才會(huì)回來。”Itwaslongbeforetheymetagain.

在他們?cè)俅我娒媲埃ǖ娜兆永铮?，時(shí)間是很長(zhǎng)的。意為“過了好久他們才又見面?！盜twon'tbelongbeforeyouregretforwhatyou’vedone.

在你后悔你的所作所為之前，時(shí)間不會(huì)長(zhǎng)了。意為“不久你就會(huì)為你的所作所為后悔的?！币陨先?，It表示“時(shí)間”，before表示“在……之前”的本義，結(jié)合時(shí)態(tài)和肯定否定，就很容易理解句子的含義了。14.

It

happens

(seems,appears)

that句式該句式中，it是形式主語，that

引導(dǎo)的是主語從句，也可以理解成是一固定句型。It

(so)happened

It

It

(if,wh-word)

句式該句式中whether

引導(dǎo)的從句是真正主語，該句型常譯為“不論（是否，何時(shí)，何地什么等）……沒關(guān)系……”。

if

引導(dǎo)一個(gè)方式狀語從句（一說表語從句，因?yàn)榉旁谙祫?dòng)詞之后）。常譯為“看起來好像……”，如果與事實(shí)不相符合，則用虛擬語氣。It
