高考英语语法知识大全高考英语语法知识主语从句主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在末尾。It作形式主语和it引导强调句的比较。It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。例如：Itisapitythatyoudidn’tgotoseethefilm.Itdoesn’tinterestmewhetheryousucceedornot.Itisinthemorningthatthemurdertookplace.ItisJohnthatbrokethewindow.用it作形式主语的结构。Itis+名词+从句Itisafactthat…事实是…Itisanhonorthat…非常荣幸itis+形容词+从句Itisnaturalthat…很自然…Itisstrangethat…奇怪的是…itis+不及物动词+从句Itseemsthat…似乎…Ithappenedthat…碰巧…it+过去分词+从句Itisreportedthat…据报道…Ithasbeenprovedthat…已证实…主语从句不可位于句首的五种情况。if引导的主语从句不可居于复合句句首。Itissaid，(reported)…结构中的主语从句不可提前。例如：ItissaidthatPresidentJingowillvisitourschoolnextweek.(right)ThatPresidentJiangwillvisitourschoolnextweekissaid.(wrong)Ithappens…，Itoccurs…结构中的主语从句不可提前。例如：Itoccurredtohimthathefailedintheexamination.(right)Thathefailedintheexaminationoccurredtohim.(wrong)Itdoesn’tmatterhow/whether…结构中的主语从句不可提前。例如：Itdoesn’tmatterwhetherheiswrongornot.(right)Whetherheiswrongornotdoesn’tmatter.(wrong)含主语从句的复合句是疑问句时，主语从句不可提前。例如：Isitlikelythatitwillrainintheevening?(right)Isthatwillrainintheeveninglikely?(wrong)What与that在引导主语从句时的区别。What引导主语从句时在句时在从句中充当句子成分，如主语.宾语.表语，而that则不然。例如：Whatyousaidyesterdayisright.Thatsheisstillaliveisaconsolation.高考英语知识重点1.abandonv.放弃，抛2.abilityn.能力;才能3.abnormaladj.不正常的4.aboardprep.&adv.在(或上)船、飞机、火车等5.abolishv.废除6.abortionn.流产7.abroadadv.到(在)国外8.abruptadj.突然的9.absencen.不在，缺席10.absentadj.缺席，不在11.absoluteadj.绝对的12.absorbv.吸收13.abstractadj.&n.抽象(的)14.absurdadj.荒谬的15.abundantadj.丰富的16.abusev.滥用，虐待17.accessn.&v.接近，进入高考英语必备知识1.:LanternFestival2.：Embroidery3.：Double-NinthFestival4.节：TombSweepingDay5.剪纸：PaperCutting书法：Calligraphy：(SpringFestival)Couplets8.象形文字：Pictog
