高考英語語法知識大全

高考英語語法知識大全高考英語語法知識主語從句主語從句是在復(fù)合句中充當(dāng)主語的從句，通常放在主句謂語動詞之前或由形式主語it代替，而本身放在末尾。It作形式主語和it引導(dǎo)強(qiáng)調(diào)句的比較。It作形式主語代替主語從句，主要是為了平衡句子結(jié)構(gòu)，主語從句的連接詞沒有變化。而it引導(dǎo)的強(qiáng)調(diào)句則是對句子某一部分進(jìn)行強(qiáng)調(diào)，無論強(qiáng)調(diào)的是什么成分，都可用連詞that。被強(qiáng)調(diào)部分指人是也可用who/whom。例如：Itisapitythatyoudidn’tgotoseethefilm.Itdoesn’tinterestmewhetheryousucceedornot.Itisinthemorningthatthemurdertookplace.ItisJohnthatbrokethewindow.用it作形式主語的結(jié)構(gòu)。Itis+名詞+從句Itisafactthat…事實(shí)是…Itisanhonorthat…非常榮幸itis+形容詞+從句Itisnaturalthat…很自然…Itisstrangethat…奇怪的是…itis+不及物動詞+從句Itseemsthat…似乎…Ithappenedthat…碰巧…it+過去分詞+從句Itisreportedthat…據(jù)報道…Ithasbeenprovedthat…已證實(shí)…主語從句不可位于句首的五種情況。if引導(dǎo)的主語從句不可居于復(fù)合句句首。Itissaid，(reported)…結(jié)構(gòu)中的主語從句不可提前。例如：ItissaidthatPresidentJingowillvisitourschoolnextweek.(right)ThatPresidentJiangwillvisitourschoolnextweekissaid.(wrong)Ithappens…，Itoccurs…結(jié)構(gòu)中的主語從句不可提前。例如：Itoccurredtohimthathefailedintheexamination.(right)Thathefailedintheexaminationoccurredtohim.(wrong)Itdoesn’tmatterhow/whether…結(jié)構(gòu)中的主語從句不可提前。例如：Itdoesn’tmatterwhetherheiswrongornot.(right)Whetherheiswrongornotdoesn’tmatter.(wrong)含主語從句的復(fù)合句是疑問句時，主語從句不可提前。例如：Isitlikelythatitwillrainintheevening?(right)Isthatwillrainintheeveninglikely?(wrong)What與that在引導(dǎo)主語從句時的區(qū)別。What引導(dǎo)主語從句時在句時在從句中充當(dāng)句子成分，如主語.賓語.表語，而that則不然。例如：Whatyousaidyesterdayisright.Thatsheisstillaliveisaconsolation.高考英語知識重點(diǎn)1.abandonv.放棄，拋2.abilityn.能力;才能3.abnormaladj.不正常的4.aboardprep.&adv.在(或上)船、飛機(jī)、火車等5.abolishv.廢除6.abortionn.流產(chǎn)7.abroadadv.到(在)國外8.abruptadj.突然的9.absencen.不在，缺席10.absentadj.缺席，不在11.absoluteadj.絕對的12.absorbv.吸收13.abstractadj.&n.抽象(的)14.absurdadj.荒謬的15.abundantadj.豐富的16.abusev.濫用，虐待17.accessn.&v.接近，進(jìn)入高考英語必備知識1.:LanternFestival2.：Embroidery3.：Double-NinthFestival4.節(jié)：TombSweepingDay5.剪紙：PaperCutting書法：Calligraphy：(SpringFestival)Couplets8.象形文字：Pictog
