高一英語上重要語法講解

情態(tài)動詞1.情態(tài)動詞的推測表達(dá)2.情態(tài)動詞表達(dá)虛擬語氣3.某些情態(tài)動詞的特殊用法知識重點(diǎn)與難點(diǎn)總結(jié)知識重點(diǎn)：情態(tài)動詞在表達(dá)推測意義的句子中的運(yùn)用：（一）用情態(tài)動詞表達(dá)事實(shí)的推測。can，could，might，may，must可以用來表達(dá)對事實(shí)的推測。根據(jù)說話人對事實(shí)的把握性大小，must表示“肯定…”，may/might/can/could表示“可能……”，must只用于肯定句中，may/might的否定式maynot/mightnot表示“可能不……”,而can/could可以用于疑問句，表示“可能，可能……嗎?”，其否定式can’t/couldn’t表示“不可能”。用情態(tài)動詞可以對現(xiàn)在或過去的事實(shí)進(jìn)行推測。對不同的時間內(nèi)容推測有不同的結(jié)構(gòu)。（二）對現(xiàn)在的事實(shí)進(jìn)行推測：主要結(jié)構(gòu)：…must/may/might+動詞原形be+名詞/形容詞/介詞短語be+doing例句：1.YoumustbeJeanne.I’mMathildeLoisel.Weusedtoknoweachotherverywell.2.Theymustbeinbedalreadyatthistimeofthenight.3.Theteachermustbejoking.4.Fredaisn’tinclass.Shemustbesick.5.Theremustbesomethingwrong.6.Shemightbeveryclever,butshehasn’tgotmuchcommonsense.7.Hemaybearrivingthisevening.8.Hemaybetravelingaroundtheworld.9.Thekeyscan’tbeintheroom.Ihavejustsearcheditverycarefully.10.Canthenewsbetrue?（三）對過去的事實(shí)進(jìn)行推測：結(jié)構(gòu)：情態(tài)動詞+havedone/been+名詞/形容詞/介詞短語例句：1.Mrs.Longmansmusthavebeenaprettygirlinheryouth.2.Hecouldn’thaveseenAnnayesterday.She’sgoneabroad.3.IthinkImusthaveleftmyglassesinthelibrary.4.Hemighthaveoversleptagain.5.WherecanTomhavegone?情態(tài)動詞表達(dá)虛擬語氣：表達(dá)“本來…”，“不然早就…”。這是情態(tài)動詞的一種虛擬語氣用法。表示說話人所講的與所發(fā)生的事實(shí)相反。表達(dá)了說話人的埋怨，后悔的語氣。其結(jié)構(gòu)是在一些情態(tài)動詞后面加havedone結(jié)構(gòu)。根據(jù)要表達(dá)的意思，有如下結(jié)構(gòu)：shouldhavedone/oughttohavedone：本應(yīng)該……shouldn’thavedone/oughtn’ttohavedone：本不該……couldhavedone：本來可以……needn’thavedone：本來沒必要……wouldliketohavedone：本來很想……wouldrathernothavedone:本來不愿意……could/might/havedone:不然早就……例句：1.Youshouldn’thavelaughedathismistakes.2.Youcouldhavetoldusearlier.3.Ioughttohaveboughtthatdictionarylastweek.4.Yououghtnottohavespentsomuchtimeinreadingnovels.5.Weneednothavebeeninatearinghurrytocatchthetrain.6.Theywouldliketohaveseenthatfilmlastfilm.7.Ifhehadgivenmehisnumber,Icouldhavetelephonedhim.8.Theymighthavebeenfrozentodeathbutfortherescueintime.知識難點(diǎn)：某些情態(tài)動詞的特殊用法：need和dare的兩種形式的用法need和dare可以用做實(shí)義動詞，后面接不定式（todo）結(jié)構(gòu)，在疑問句和否定句中，加助動詞do/does/did/或don’t/doesn’t/didn’t。作為情態(tài)動詞使用時，主要用于疑問句和否定句中。情態(tài)動詞needn’t（沒有必要，不必）相當(dāng)于don’thaveto例句：1.Itiscold,youneedtowearsomewarmclothes.2.NeedIstayherewithyouforawhile?Thankyou,youneedn’t.3.Howdareyouspeaktoparentslikethat?注意：句型Idaresay+從句。意思是：我肯定……=I’msure或Thereisnodoubtthat+從句。例句：IdaresaythatmyunclewillgetthemoneyifIdie.will和would表示“意志”或“愿意”，would則指過去愿意做……例句：1.Hesaidthathewouldhelpus.2.Youmaytelephoneifyouwillacceptthisjob.would可以表達(dá)“過去習(xí)慣做……”類似于“usedtodo”例句：1.Whenwewerechildren,wewouldgoswimmingeverysummerinthatriver.表示請求，固定的句型：Will/Wouldyoupleasedo…?/Wouldyouliketodo…?例句：Will/Wouldyoupleasegivehimamessagewhenyouseehim?shall1.用于第一，三人稱，表示“請求”；“建議”或“推薦”例句：1.Shallwestartthemeetingnow?2.ShallIwatchTVnow?3.Shallmysoncarrythecaseforyou?2.用于第二人稱，表示“命令，“要求”，“許諾”例句：1.Youshalltakewhateveryoulike.2.Youshallnotgotothepartywithmeifyoumakesomuchnoiseagain.在表示推測的否定句或疑問句中，常用can/can’t/could/couldn’t表示，意思是：“可能…嗎?”；“…不可能…”。而不能使用mustn’t或must等詞。【典型例題】1.—Doyouthinkhewilldomeafavor?

答案為：B與it有關(guān)的主要句型it強(qiáng)調(diào)句型知識總結(jié)歸納：（一）it用做形式主語或形式賓語：根據(jù)句子結(jié)構(gòu)的需要，it用做形式主語或形式賓語，而真正的主語或賓語（todo短語，doing短語，名詞性從句）則放在句尾。主要句型：It’s+形容詞/名詞+連詞+名詞性從句todosth.doingsth.find/make/think/feelit+形容詞/名詞+連詞+名詞性從句todosth.doingsth.例句：1.ItwillbecomemoreandmoreimportanttohaveagoodknowledgeofEnglish.2.It’susualforclosefriendstohavesimilarideasandbeliefs.3.It’sapitythatIdidn’tthinkofitearlier.4.It’snousegoingtheresoearly.5.Outteacherthinksitnogoodlearningwithoutpractice.6.Didn’tImakeitcleartoyouthatIwasnotcoming?7.Wefounditstrangethatnoonewouldtakethemoney.（二）其他句型1.Ittakes+時間段+sb.+todosth.2.表示“據(jù)說，據(jù)報道，/人們認(rèn)為/相信/建議等It’ssaidthat…….It’sreportedthat……It’sbelieved/thought/suggestedthat……例句：1.Itgenerallytakestimetoreachthispoint—beingonthesamewavelength.2.Itisbelievedthatthetwochildrenwentoffexploring（探險）ontheirownandgetstuckonthecliff.3.It’ssuggestedthatweshouldhaveameetingtodiscusstheproblem.4.Itwasoncepredicted（預(yù)測）thatBritishandAmericanEnglishwouldbecomeseparatelanguagesfinally.（三）it在強(qiáng)調(diào)句型中：在英語中，為了突出強(qiáng)調(diào)句子的某一個成分（謂語除外），達(dá)到強(qiáng)調(diào)或使聽話人特別注意這一部分的目的。便形成了一種強(qiáng)調(diào)句型。Itis/was+被強(qiáng)調(diào)的部分+that/who+句子的其他部分。Itis/wasnotuntil+時間+that+句子的其他部分。例句：1.IsawJohnonmywaytoschoolthismorning.ItwasJohnwho/thatIsawonmywaytoschoolthismorning.ItwasonmywaytoschoolthatIsawJohnthismorning.ItwasthismorningthatIsawJohnonmywaytoschool.2.ItwashisbestsuitthatJohnworetothedancelastnight.3.Itwasnotuntil1920thatregularradiobroadcastbegan.4.Itwasthestrangewaythingslookedandsoundedinmyfamiliarroomatnightthatfrightenedmesomuch.5.Itwasthekindnessandsympathyintheireyesthatpreventedmefromdoingso.知識難點(diǎn)：（一）注意強(qiáng)調(diào)句型的變形，即以一般疑問句或特殊疑問句的形式出現(xiàn)的強(qiáng)調(diào)句型。1.WhatisitthatJoecan’tfindinthebathroom?2.WherewasitthatyoumettheforeignguestsfromAustralia?3.Ican’tquiterememberwhenitwasthatwemarried.4.Wasitbecausehewasveryillthatheaskedforleave?（二）是強(qiáng)調(diào)句型還是that主語從句或其他復(fù)合句1.ItisafactthatEnglishisbeingacceptedasaninternationallanguage.2.Itisthesepoisonousproductsthatcancausethesymptomsoftheflu,suchasheadacheandachingmuscles.3.Itwasalmostteno’clockwhenoursoldierscamebackfromthefront.4.Wasitinthisplacethatthelastkingdied?（三）注意強(qiáng)調(diào)句型中被強(qiáng)調(diào)部分帶有定語從句WasitattheairbattleonJune8,1944,whichwasledbyCaptainJohnsonthatPeterlosthislife.【典型例題】一.單項(xiàng)選擇：1.Idon’tthinkpossibletomasteraforeignlanguagewithoutmuchmemory.A.this
