常用句型,慣用法及it用法

常用句型，慣用法及it用法核心提示：一、it用作代詞，代替前面提到過的人或事。二、it可用來指天氣、時(shí)間、距離、自然環(huán)境等。三、it可用來指說話雙方都知道的事物。四、it可用來指整個(gè)句子所表達(dá)的意思。五、it用作形式主語(yǔ)，代替句子后面的真正主語(yǔ)——不定式、動(dòng)名詞或that從句。六、it用在find，feel，think，consider，make，take等動(dòng)詞之后，作形式賓語(yǔ)，代替后面的真正的賓語(yǔ) 不定式、動(dòng)名詞或that從句。七、掌握it在強(qiáng)調(diào)句型中的用法八、it用于習(xí)語(yǔ)中。一、 it用作代詞，代替前面提到過的人或事。如：－Isthebabyaboyoragirl?－It'saboy.（it指上文提到的baby）ThedoctoradvisedVerastronglythatsheshouldtakeaholiday,butitdi'dnthelp.（it指上文敘述的事）注意：it,that,one都可用來代替前面提到的人或事，但這三個(gè)代詞之間有不同之處：it用來代替前面提到的可數(shù)名詞，并且it所指的是事物本身；that用來代替不可數(shù)名詞，指的是前面提到的名詞中的同一類事物；one則用來代替前面出現(xiàn)過的可數(shù)名詞，并且是指這類事物中的一個(gè)。如：Ican'tfindmypenanywhere.Imusthavelostit.（it指前面的pen本身）Lifetodayismuchbetterthanthatintheolddays.（that指代前面提到的life）Ican'tfindmypen.I'mgoingtobuyone.（one指前面的pen這類事物中的一個(gè)）二、 it可用來指天氣、時(shí)間、距離、自然環(huán)境等。如：ItwasverycoldinBeijinginwinter.（it指天氣）WhatalongwayitisfromBeijingtoLondon!（it指距離）ItwastoolateandIhadtoleaveforhome.（it指時(shí)間）Itwasquietintheschoolatnight.（it指自然環(huán)境）三、 it可用來指說話雙方都知道的事物。如：Wheredoesithurt?還可用來指人，特別是不知對(duì)方的性別時(shí)。如：Whosebabyisit?It'sverylovely.四、 it可用來指整個(gè)句子所表達(dá)的意思。如：Shefailedtheexaminationanditmadeherparentsworried.五、 it用作形式主語(yǔ)，代替句子后面的真正主語(yǔ) 不定式、動(dòng)名詞或that從句。如：It'snecessaryforustotellhimallaboutthat.Itisnousedoingthatagain.Itisimportantthatstudentsshouldlearntheirlessonswell.六、 it用在find，feel，think，consider，make，take等動(dòng)詞之后，作形式賓語(yǔ)，代替后面的真正的賓語(yǔ) 不定式、動(dòng)名詞或that從句。如：WeallthinkitimportanttolearnEnglishwell.Weallfeelitnecessarythatstudentsshouldobeyschoolrules.七、 掌握it在強(qiáng)調(diào)句型中的用法：it用于強(qiáng)調(diào)句型"Itis（was）...that/who…"中。這個(gè)句型可以對(duì)句子中除謂語(yǔ)外的任何一個(gè)成分進(jìn)行強(qiáng)調(diào)。it用于強(qiáng)調(diào)句型時(shí)，應(yīng)注意對(duì)以下幾個(gè)方面的把握：強(qiáng)調(diào)時(shí)間狀語(yǔ)時(shí)，不要將強(qiáng)調(diào)句型與“Itis...since/before...”句型混淆了。強(qiáng)調(diào)句型有以下兩個(gè)典型的特征：1)it不表示具體內(nèi)容；2)被強(qiáng)調(diào)部分是時(shí)間或地點(diǎn)狀語(yǔ)時(shí)，通常在表示時(shí)間或地點(diǎn)的名詞前面有一個(gè)介詞。而在“Itis...since/before”句型中，it表示時(shí)間。試比較：Itisfiveyearssincehelefthome.(it表示時(shí)間)Itwasatfiveo'clockyesterdayafternoonthathereturnedhomefromBeijing.(強(qiáng)調(diào)句型)強(qiáng)調(diào)句型的一般疑問結(jié)構(gòu)為：“Is(Was)it+被強(qiáng)調(diào)部分+who/that+其它”。如:WasitinBeijingthatyoufirstmether?強(qiáng)調(diào)句型的特殊疑問句形式是：“特殊疑問詞+was/is+itthat+其它”。如：Wherewasitthatyousawhimyesterday?不管被強(qiáng)調(diào)的部分是單數(shù)還是復(fù)數(shù)，it后面只能用單數(shù)系動(dòng)詞is/was。如：ItwasMikeandhissisterwhowerepraisedatthemeeting.如果被強(qiáng)調(diào)部分是原句中的主語(yǔ)，則要注意that或who后面句中的謂語(yǔ)動(dòng)詞要與被強(qiáng)調(diào)部分在人稱和數(shù)上保持一致。如：ItisIwhoIamwrong.八、it用于習(xí)語(yǔ)中。如：makeit成功，按時(shí)到達(dá)某地；seetoitthat...確保；callitaday今天就到此為止；takeiteasy慢慢來；that'sit就這樣，這就對(duì)了；sb.wouldappreciateitif…如果……會(huì)感激的;gotit明白啦。常用句型及慣用法倍數(shù)表達(dá)法：AisXtimes+形容詞或副詞比較級(jí)thanB/AisXtimesas+形容詞或副詞原級(jí)asB/AisXtimesthesize(height,length,width,amount...)ofB。It+be+一段時(shí)間+before/since...“過了一段時(shí)間才……”。表示"一 就 ”:nosoonerhad+主語(yǔ)+than.../hardlyhad+主語(yǔ)+when.../scarcely*had+主語(yǔ)when.../themoment/theminute/theinstant.../directly/immediately/instantly.../assoonas.../ondoing...。祈使句+and(andthen)+陳述句/祈使句+or(orelse或otherwise"陳述句。詢問對(duì)方的看法“……怎么樣?”Howdoyoulike...?/Whatdoyouthinkof...?/Howdoyoufind.？../Whatissb.(sth.)like?/Howissb.(sth.)?/Whatabout...?/Howabout...?so(such)...that引導(dǎo)的結(jié)果狀語(yǔ)從句。with復(fù)合結(jié)構(gòu)：with+名詞或代詞+todo/動(dòng)詞-ing形式/過去分詞/形容詞/副詞/介詞短語(yǔ)。以so開頭的句子Sodo/did/can/have...I我也……;SoIdo/can/did/have我的確……。表示“有”或“存在”的therebe句型：Thereused/seem/happen/appear…tobeTheremust/might/oughtto...beTherestands/exists/lives...感嘆句型：How+adj./adv.+主謂部分How+adj.+a/an珂數(shù)名詞單數(shù)+主謂部分=What+a/an+adj.+可數(shù)名詞單數(shù)+主謂部分What+adj.+名詞復(fù)數(shù)+主謂部分What+adj.+不可數(shù)名詞+主謂部分if/when/unless...+非謂語(yǔ)動(dòng)詞、形容詞、介詞短語(yǔ) ，+主句(注：在此句型中從句的主語(yǔ)與主句的主語(yǔ)一致或從句的主語(yǔ)是it,從句中省略了主語(yǔ)it以及be動(dòng)詞)。如：Weallknowthat,ifnotcarefullydealtwith,thesituationwillgetworse.(此句中ifnotcarefullydealtwith=ifthesituationisnotcarefullydealtwith)由使役動(dòng)詞或感官動(dòng)詞構(gòu)成的句型：makesb./sth.dosth.或makesth.donehavesb./sth.do/doingsth.或havesth.donesee/watch/hear/notice/observe...sb./sth.do/doing(done)看到/聽到/注意到/觀察到某人或某物……【經(jīng)典句型展示】(注意句中的劃線部分就是本句型中的關(guān)鍵詞)Ihavenoideawhethertheywillbeabletocompletetheirworkintime.Thereisnodoubtthatourcountrywillbemoreandmorepowerfulinthefuture.Myideaisthatyoushoulddiscussyourproblemswithyourparentsfirst.Youcangivethebooktowhoeverisintheoffice.Whateverhedoesmatterslittletous.WhatI'mstillnotsoclearishowshemanagedtoarriveherejustintime.Hedidn'tturnupatthemeetinguntilwecalledhimmanytimes.Nomatterwhatyoudo,youshouldkeeptothelaw.Itbegantorainthemoment/instant/minuteIlefthome.WhileIagreetothisplan,Idon'tthinkitisperfect.Whyareyouherewhenyoushouldbeinschool?Ihadhardlyputdownthephonewhenitrangagain.ShehadrushedoutintotherainbeforeIcouldexplain.Youcan'tgotothefilmwithmeunlessyouhavedoneyourhomework.Itwillbetwomonthsbeforehecomesbackfromforeigncountries.Itisquitesometimesincewelastenjoyedourselvessomuch.Thereasonwhyhedidn'tturnupatthemeetingwasthathehadn'tbeeninformedofit.Morethanfourhundredpassengersgotinjuredintheaccident,mostofwhomhavegotwell.Thatboywascaughtcheatinginthefinals.Hehurriedtotheairport,onlytofindthathisfriendshadalreadyleft.It'snousecryingoverspiltmilk.Thereisnopointinquarrellingwithsuchanoldlady.Amiddle-agedmanislyingasleepunderthetreewithhismouthwideopen.Sheisreportedtohavewonseveralgoldmedalsinthe29thOlympicGames.（=Itisreportedthatshehaswonseveralgoldmedalsinthe29thOlympicGames.）Ihadhoped/intended/meanttoseeyoulastweek,butIwastoobusy.Sheseemedtobewornout.（=Itseemedthatshewaswornout.）Allyouneedtodois（to）pushthebutton.Ithasrainedforawholeweek,makingitmoredifficultforustofinishourworkintime.OnlythendidIrealizewhathadhappenedinmyoffice.Childasheis,heknowsmuchmorethanIdoincomputer.Sobeautifullydidshedancethatalltheaudiencestooduptoclaphands.Nosoonerhadshearrivedatthestationthanthetrainleft.Hardlyhadshecompletedherhouseworkwhenthelightwentout.Shewasabouttoleavetheroomwhenthetelephonerang.Comeoverhere,andI'lltellyousomethingimportant.Hurryup,or（otherwise）you'llbelate.IwishIhadn'tboughtsuchalargecarformypersonaluse.IfonlyIhadtakenyouradviceyesterday!I'dratherthatIhadn'ttoldherthenews.Youneedn'thavesentherthatsumofmoneybypostbecausesheiscomingheretomorrow.【高考鏈接】從A、B、C、D四個(gè)選項(xiàng)中，選出可以填入空白處的最佳選項(xiàng)?！狧egothisfirstbookpublished.Itturnedouttobeabestseller.—Whenwas
