1、2011高考英语必读：It构成的20个句型（1）来源：天星更新日期：2010-10-07点击：361一、it做强调句1.Itis+被强调部分+that...该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，表语 或状语。强调的主语如果是人，that可以由who换用。如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。Itwasabout600yearsagothatthefirstclockwithafaceandanhourh
2、andwasmade.Itwastheythat(who)cleanedtheclassroomyesterday.ItwasinthestreetthatImetherfather.2.Itisnotuntil+被强调部分+that...该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到……才……＂，可以说是not...until...的强调形式。ItwasnotuntilshetookoffherdarkglassesthatIrealizedshewasafamousfilmstar.=Notun
3、tilshetookoffherdarkglassesdidIrealizeshewasafamousfilmstar.=Ididn'trealizeshewasafamousfilmstaruntilshetookoffherdarkglasses.二、it做形式宾语20.Wethinkitimportanttolearnaforeignlanguage.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,consid
4、er,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。Wethinkitourdutytocleanourclassroomeveryday. HefeltitimportantlearningEnglishwell.Theyfounditdifficultthattheywouldfinishtheirworkintwodays.三、it做形式主语3.Itisclear(obvious,true,possibl
5、e,certain....)that.....该句型中it是形式主语，真正的主语是that引导的主语从句，常译为＂清楚（显然，真的，肯定……）＂是主语从句最常见的一种结构。Itisveryclearthathe'sroundandtalllikeatree.=Thathe'sroundandtalllikeatreeisveryclear.4.Itisimportant(necessary,right,strange,natural...)that...该句型和上一个同属一个句型,做形式主语。 要用虚拟语气（
6、should+动词原形），should可以省去。建议记住该句型中的形容词。Itisimportantthatwe(should)learnEnglishwell.Itisnecessarythathe(should)rememberthesewords.5.Itissaid(reported,learned....)that...该句型中的it仍是形式主语，真正主语是that引导的主语从句。该结构常译为＂据说（据报道，据悉……）＂。ItissaidthathehascometoBeijing.Itisrepo
7、rtedthatanotherearthsatellitehasbeenputintoorbit.6.Itissuggested(ordered...)that...该句型和上一个同属一个句型，形式主语。主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should+动词原形），should可以省。常译为＂据建议；有命令……）Itissuggestedthatthemeeting(should)beputoff.Itwasorderedthatwe(should)arrivether
8、eintwohours.13.Ithappens(seems,looks,appears)that...该句型中it是形式主语，that引导的是主语从句，主句中的happen,seem等词是不及物动词．Ithappened(sohappened)thathemethisteacherinthestreet.碰巧……Itseemsthathewillbebackinafewdays.看来……14.It
