I.It 作形式主语的句型

①It+be+adj(kind, wise ,careless,clever?) +ofsbtodosth

Eg:Itiswiseofhimtomakesuchadecision.他做出这样的决定是明智的。

②It+be+adj(easy,safe,common,normal ?)+forsbtodosth

该句型中adj若为important,necessary,natural,possible,strange,vital,essential等可改为从句,从句用should+动词原形。

.Eg:It’sverydangerousforchildrentoplaywithfire.

ItisimportantforustolearnEnglishwell.(=Itisimportantthatwe(should)learnEnglishwell.)

③ It+be+V-ed(reported,believed,said, suggested?)+that 从句

该句型中:⑴若V-ed为reported,believed,said等常译为“据报道”,“据认为”,“据说”。⑵若V-ed为suggested,ordered,demanded,insisted等表示“建议”,“命令”的词,从句要用虚拟语气(should)+动词原形。

Eg:Itissuggestedthatthebook(should)berevised.

It’ssaidthatTomhasbeenbackfromabroad.(=Tomissaidtohavebeenbackfromabroad.)

④ It+be+ n(apity, ashame, afact,goodnews?)+that 从句:

该句型中,从句一般用(should)+动词原形,表示出乎意料,常译为"竟然"。

Eg:Itisapitythatsuchathing(should)happeninyourclass.这种事竟然发生在你们班上,真是遗憾!

⑤ Itisuseless/nouse/nogood /pleasure+doingsth

此句型中的it是形式主语,其后的动名词短语是真正的主语,译为“做?没有用”。

Eg:It‘suselessarguingwithhimfurther.//It’snousetalkingwithhim,becausehewon’tlisten.

⑥ Ittakessb....todosth.

该句型中it是形式主语,真正的宾语是todosth,常译为"做??要花费某人??"。

Eg:IttookthousandsofpeoplemanyyearstobuildtheGreatWall.

II.It 作形式宾语的句型

1.sbfind/believe/think/feel/consider/make+it+n/adj+todo或从句

该句型中的it作形式宾语。为了记忆方便我们可称该句型为“6123结构”。6指主句中常用的动词:think,believe,make,find,consider,feel;1指的是形式宾语it;2指的是宾补的两种形式:形容词或名词;3指的是真正宾语的三种形式:不定式短语,动名词短语或that引导的宾语从句。

Eg:Wethinkitourdutytocleanourclassroomeveryday.

HefeltitimportantlearningEnglishwell.

Theyfounditdifficultthattheywouldfinishtheirworkintwodays.

2.主语+hate/dislike/love/like +it +when-从句

Eg:Ihateitwhenpeoplespeakwiththeirmouthsfull.

3. 主语+appreciate +it +if-从句

Eg:Ireallyappreciateitifyoucouldhelpmewithmymath.

4. sb.dependon/counton/relyon/seeto(负责,确保)/answerfor itthat?

Eg:Youmayrelyonitthathewon’tbelate.

Youmustseetoitthatthedoorsarelockedbeforeyouleavethelab.

5. sb.takeitforgrantedthat? 认为??是理所当然的

Eg:Itakeitforgrantedthathewillsucceed.

III.It 引导的时间句型

⑴ It+is/hasbeen+ 时间段+since引导的时间状语从句:

该句型中从句一般用过去时态,句意为“自从......以来已多久了”

Eg:Itis5minutessincethebusleft.公汽开走已有5分钟了

⑵ It+be(will/was)+ 时间段 +before引导的时间状语从句:

该句型中,主句谓语动词be若为肯定式,意为“过多久才......”;若为否定式时,意为“没过多久就......”。

Eg:Itwillbelong/3hoursbeforehecomesback.要过三个小时他才会回来

Itwas3hoursbeforehecameback.过了三个小时他才回来

⑶ It+be+ 时间点+when引导的时间状语从句

这个句型中,it代指时间,表示时间点的词前没有介词。

Eg:ItwillbeMondaywhenhecomesback.他周一的时候回来.

ItwasMondaywhenhecameback.他周一回来的.

对比:ItwasonMondaythathecameback.(强调句)

⑷ It+is(about/high)time+(that)sbdid/shoulddosth

意为“该是某人做?的时候了”,about/high是用于加强语气,that从句用should或动词一般过去时表虚拟。

亦可转换成It+is+time+(forsb)todosth.

Eg:It’s(high/about)time(that)wehandedin/shouldhandinourhomework.

⑸ It/This/That+is+thefirst(second?)time+thatsbhasdonesth:

意为“这是某人第?次做?”,注意time前有序数词,主句是is时,从句要用现在完成时;如果主句用was,则从句须用过去完成时。Eg:ItisthethirdtimethatIhaveseenthefilm.

ThatwasthesecondtimethatIhavebeenthere.

IV.It 引导的强调句

强调句形式:It+is/was+被强调的部分+that/who从句

Eg:ItwaslastweekthatImetanoldfriendinthestreet.//Itwasbecausehewasillthathedidn'tcometoschoolyesterday.

(强调原因状语从句时,只能强调由because所引导的从句.)

判断方法:将Itis/was和that去掉,若该句是一个完整无缺的句子即为强调句.

常考考点:

①强调句型中的主谓一致Eg:Itisyou,ratherthanhe,thataretoblamefortheaccident.

②插入从句的强调句型Eg:ItwasintherestaurantwherewehaddinnerlastSundaythatyouleftyourwallet.

③强调句型的一般疑问句、特殊疑问句形式

一般疑问句:Is/Wasit+被强调部分+that+句子其余部分?Eg:Wasitin1933thattheSecondWorldWarbrokeout?

特殊疑问句:疑问词+be+it+that+句子其余部分?Eg:Whenwasitthathechangedhismindtotakepartintheactivity?

④强调句型用于名词性从句,尤其注意要使用陈述语序。

Eg:Idon’tknowwhenitwasthathechangedhismindtotakepartintheactivity?

⑤notuntil用于强调句型 Itis/wasnotuntil+被强调部分+that+其他部分

Eg:Itwasnotuntilmidnightthatshewentbackhome.

此句型只用until,不用till。但如果不是强调句型,till和until可通用。因为句型中Itis/wasnot...已经是否定句了,that后面的从句要用肯定句。

V.It其他常见用法:

Itlooks/appearsasif...看起来好像??Itlooksasifsheisill.

Itseemsthat...似乎??Itseemsthathewillbebackinafewdays.

Itturnsoutthat...原来是??Itturnedoutthatthebeautifulwomanwasathief.

Itoccursto/strikessbthat?突然想到??ItoccurredtomethatIhadn’tlockedthedoor.
