it用法专项练习题

1It的用法It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。一、要点点拔1．代替上文中提到过的人或事物。指代人时，一般用于小孩或身份不十分明朗的人。1)－Whoisthebaby?－It‘smyteacher’sson．2)－Whoisthatgentleman?－It'smyfriendTom．He(不可用It)wantstoseeyou．2．用于表达天气、环境、时间、距离、季节等。例如：1)It’shalfanhour’swalkfromheretoourschool．2)It‘sniceandwarmhere．3)Butit'stwoo'clocknow,andit'stimeforustogotoschool．3．用作形式主语.it没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。1).It替代真正的主语——动词不定式短语.Itiseasiertosaythantodo.Itisagoodacttohelptheothers.2).it替代真正的主语——动名词短语,以动名词短语做主语的句子，主要在以nogood,nouse,noharm,dangerous,foolish等词作表语的句中.It’snoharmdrinkingrunningwaterinthatarea。It’sfoolishtalkinglikethat.3).it替代从句作主语，用从句做主语的带it的句子很多,常见的有下面几类：①Itisapity(ashame,afact,awonder,agoodthing,etc.)that…Itisashamethathedidn’tpasstheexam.②Itisstrange(surprising,obvious,true,good,possible,clear,etc.)that…。Itwasclearthattheyhadnodesireforpeace.③Itseems(happened,turnedout,etc.)that…Itseemedthatthingswerenotastheyexpected.④Itissaid(decided,expected,etc)that…Itissaidthattheticketshavebeensoldout.4.用作形式宾语。当复合宾语中的宾语是不定式,－ing短语或从句往往用it作形式宾语,而将真正的宾语移至句末,句子重心后移。1)WefinditdifficulttolearnEnglishwellinsuchashorttime．2)Wethinkitnousecryingoverspiltmilk．3)Wemadeitclearwhenandwhereweweregoingtohavethemeeting．5．用于强调句型，即“Itis/was＋被强调部分＋that/who/whom+其它”句型之中。使用该句型有以下几点请注意：①强调句的谓语is或was永远用单数.ItwasyesterdaythatImetyourfatherinthestreet．②不管被强调部分是哪种状语，只能用that连接，不得使用where、when等连词.ItwasinthestreetthatImetyourfatheryesterday．③被强调部分为人时，可用who(主格或宾格)和whom(宾格)代替that，用that也行。1)Itwasyourfatherthat/whom/whoImetinthestreetyesterday．22)ItwasIthat/whometyourfatherinthestreetyesterday．④强调句中也要注意主谓一致、人称一致和否定转移的问题。1)Itistheywhoareourfriends．2)Itwasnotuntilteno'clockthatwegothomelastnight．⑤注意不要混淆强调句和其他从句。Itiswas…that…为强调句标志，去掉后仍可组成一个完整的句子，只是没被强调,而其他从句一般不具备这一特征。比较：1)Itwasteno'clockwhenwegothomelastnight．我们昨晚到家时已十点了。2)Itwasatteno'clockthatwegothomelastnight．我们昨晚是在十点到家的。第一句不是强调句，when不可改为that,因为去掉itwas和that后，只能组成“Wegothometeno'clocklastnight．”这样一个不完整的句子；第二句是强调句，that不可改为when．二、常用句型及考点I.形式主语型1.Itisclear(obvious，true，possible，certain…)that…2.Itisimportant(necessary，right，strange，natural…)that…掌握本句型，应该记住所列举的形容词，并且记住that后的从句应用虚拟语气(should+动词原形)，should可以省去。3.Itisnogood(use)doingsth．4.Itisapity(ashame…)that…本句型中，that后的从句一般用虚拟语气(should十动词原形)，should可以省去。表示出乎意料，常译为“竟然”。没有这种意义时，则不用虚拟语气。5.Itistime(abouttime，hightime)that…本句型中that后的从句应该用虚拟语气。6.Itisthefirst(second…)timethat…7.Itissaid(reported，learned…．)that…8.Itissuggested(ordered…)that…本句型中的过去分词应该是表示请求、建议、命令等的词，that后的从句要用虚拟语气(should十动词原形)，should可以省略。常译为“据建议；有命令……”。9.Ithappens(seems，appears)that…10.Ittakessb…todosth．11.Itdoesn’tmatterwhether…12.Itiskind(ofsb)todosth．本句型中的不定式如果需要逻辑主语，则须要前置介词of，而句型中的形容词必须是能表示逻辑主语特征的形容词，常见的有bad，brave，careless，clever，cruel，foolish，honest，horrible，kind，lazy，modest，naughty,polite，rude，silly,stupid，wise，wrong等。13.Itisnecessary(forsb)todosth．14.Itis(just)likesbtodosth．本句型为“某人(恰恰)是……样子”。用来表示赞扬或不满，若用否定式，则表示怀疑。例：It'slikehimtoleavetheworktoothers．他就是这样的一个人，把工作推给别人。15.Itisuptosbtodosth．本句型表示“谊由某人做……”。II．强调句型Itis+被强调部分+that/who…本句型中被强调部分可以是主语、宾语或状语。强调的主语如果是人，that可以由who换用。3III．其他句型1.Itis…since…本句型主句中用时间作表语，一般用现在时或完成时，since引导的从句常用瞬间动词的一般过去时态。主句如用一般过去时，则从句用过去完成时。2.Itis…when…本句型中的when引导的是一个时间状语从句，主句中的it指时间，表语由具体的时间充当。3.Itlooks(seems)asif．．．本句型中的asif引导一个状语从句，常译为“看起来好像……”。如果与事实不相符合，则用虚拟语气．例1Itlooksasifheisill(真的病了).例2Itlooksasifhewereill(没有生病).一．替代词it,that,(the)one(s),those的用法辨析1.Theawardontheleftismorebeautifulthan_______ontheright.AtheoneBoneCitDthis2.Fewpleasurescanequal________ofacooldrinkonahotday.A.someB.anyC.thatD.those3.Thehunter’syoungersisteristallerthantheelder___.AtheoneBoneCthatDthis4.Ineedtheplasticbags,notthepaper______.AtheoneBonesCthatDthis5.TheTVsetsmadeinChinaaremuchbetterthan________inJapan.A．thatB．thoseC．themD．It6.Listento________!Wewillhavethreedaysoff.AtheoneBonesCthatDthis7.“Apennysavedisapennyearned.”Whosaid_________?AtheoneBonesCthatDthis8.IboughtadictionarythreeyearsagoandIamstillusing______now.AoneBonesCitDthis9.IboughtadictionarythreeyearsagobutIamgoingtobuyanew_______soon.AoneBonesCitDthis10.Iwasdisappointedwiththefilm.Ihadexpected____tobemuchbetter.A.thatB.thisC.oneD.it11Equippedwithmodernfacilities,today'slibrariesdiffergreatlyfrom______.A.thoseofthepastB.thepastC.whichofthepastD.thesepast12.Mymostfamousrelativeofall,______whoreallylefthismarkonAmerica,wasRebSussel,mygreat-grandfather.A.oneB.theoneC.heD.someone13.Hehasonebluepenandtwored________.A.oneB.thoseC.one'sD.ones14.Carsdocauseussomehealthproblems—infactfarmoreseriousthan_____mobilephonesdo.A.oneB.onesC.itD.those15.Cookwasastrictbutgoodcaptain,______whotookgoodcareofthesailorsonhisship.A.thatB.oneC.itD.what16.MrZhanggavethetextbookstoallthepupilsexcept____whohadalreadytakenthem.A.theseB.onesC.theonesD.theothers17.——I'mlookingforaflat.——Wouldyoulike____with____garden?4A．it;theB．it;aC．one;aD．one;the18.Meetingmyuncleafteralltheseyearswasanunforgettablemoment,___Iwillalwaystreasure.A.thatB.oneC.itD.what19.Thestyleofthebuildingissimilarto_________ofatemple.A.thatB.on
