It作形式宾语用法总结

It做形式宾语用法总结当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾，构成“动词＋it＋宾语补足语＋不定式（动名词或从句）”结构，也可称作“6123结构”。此时it仍只起先行引导作用，本身无词义。它可以代替三种形式：不定式、动名词和宾语从句。it作形式宾语时，需具备两个条件：①真正的宾语是不定式、动名词或从句;②有宾语补足语，具备了这两个条件，形式宾语it一定要用。⒈it代替不定式短语think/find/feel/consider/make/regard…+it+形容词/名词+不定式短语如：①Ifinditpleasanttoworkwithhim.(it作形式宾语，代替不定式短语toworkwithhim)②Theyfeltitdifficulttofinishtheworkinsuchashorttime.（it作形式宾语，代替不定式短语tofinishtheworkinsuchashorttime）③Shethinksitherdutytohelpus.（it作形式宾语，代替不定式短语tohelpus）④Ithinkitmyhonortobeinvitedtospeakhere.（it作形式宾语，代替不定式短语tobeinvitedtospeakhere）⑤Tomdidn’tfinditdifficulttowritelettersinChinese.（it作形式宾语，代替不定式短语towritelettersinChinese）⑥Allthesenoisesmadeitimpossibleformetogoonwiththework.（it作形式宾语，代替不定式短语togoonwiththework）⒉it代替动名词短语(这只限于少数句型，在多数情况下用不定式时更多一些)如：①Theprofessorconsidersitnogoodreadingwithoutunderstanding.②Doyouconsideritanygoodtryingagain?③Hefoundituseless(nouse)arguingwithhim.④Hethoughtitabsolutelysenselessattemptingtheimpossible.⑤Idon’tthinkitworthwhilegoingtosuchaplace.⒊it代替宾语从句：如：①Weallthoughtitapitythattheconferenceshouldhavebeencancelled.②Itookitforgrantedthattheywerenotcoming.③I’llseetoitthateverythingisreadyintime.“it”的特殊用法常出现在以下几种结构中。A.动词＋it＋when/if从句。常见于appreciate,enjoy,like,dislike,love,hate,prefer等少数动词之后。Wewouldmuchappreciateitifyoucoulddousthatfavour.I'dpreferitifIdidn'thavetofinishthework.B.动词+it+that从句。常见于like,take,have,put等少数动词之后（it相当于that从句的同位语）。Itakeitthattheywillsucceedsoonerorlater.ThenewspapershaveitthatsomeJapanesefirmshavegonebankrupt.RumorhasitthatMaryisgettingmarried.Itakeitthatyouhavebeenout.Letmecomeandstay.Youcanputitthatitwasarrangedbefore.C.动词+it+介词短语+that从句。常见于bringittoone'sattention;oweittosb;takeitforgranted等结构中。IoweittoyouthatIfinishedmyworkintime.Don'ttakeitforgrantedthattheywillsupportyou.D.动词+介词(短语)+it+that从句。常见于answerfor,dependon,relyon,insiston,lookto,seeto,stickto等结构中。I'llseetoitthateverythingisreadyintime.YoumaydependonitthatTomwillhelpyouwithyourEnglish.I’mcountingonitthatyouwillcome.E.动词+it+过去分词+从句。常见于几个可以带过去分词作宾语补足语的动词之后。Ihearditsaidthatthatfactorywasfoundedin1995.Theyhaven'tmadeitknownwherethemeetingistotakeplace.易混用其他句型英语中有一些句型不含it,但却易被误用了it，常见的有以下句型：⒈Thereissomething/nothingwrong/thematterwithsb./sth.如：Thereisnothingwrong/thematterwithhim.He’sjustpretending.他没什么事，他只是在装呢。⒉Thereisnodoubtabout…对…毫不怀疑Thereisnodoubtthat…对…毫不怀疑如：①Thereisnodoubtabouthissuitabilityforthejob.毫无疑问，他适合这个工作。②Thereisnodoubtaboutthefact.关于这个事实毫无怀疑。③Thereisnodoubtthatheishardtodealwith.毫无置疑他很难对付。⒊Thereisnoneed(forsb.)todosth.没必要…如：①TherewasnoneedforhimtoremaininParis.他没有必要继续留在巴黎。②Thereisnoneedforyoutostartyet.你现在还不必动身。⒋Thereisno/apossibilitythat……没可能/有可能(=Itisimpossible/possiblethat…)如：①Thereisapossibilitythatthetrainmaybelate.可能火车要晚点。②Thereisnopossibilitythatwe’llseehimthisweekend.我们本周末不可能见到他。⒌Thereisachancethat…可能…如：Thereisachancethatthesickchildwillgetwell.这个生病的孩子可能会好起来的。⒍Therebeno/somedifferencesbetween…and……和…之间没/有区别如：Therearesomedifferencesbetweenthetwolanguages.这两种语言之间有些区别。⒎Afterwhatseemed+时间如：Afterwhatseemedaverylongtime,thewoundedsoldiercamebacktolife.在经过似乎很长的一段时间之后，那个受伤的士兵苏醒了过来。⒏Therebedifficulty/trouble(in)doingsth.干…有困难如：Therewasnodifficultyinfindinghim.找到他没费什么事。
