連詞專題一．連詞連詞：用來(lái)連接詞，短語(yǔ)，從句或句子的詞叫連詞。連詞是一種虛詞，在句中不能單獨(dú)使用。連詞可分為兩類：并列連詞和從屬連詞。1.并列連詞并列連詞用來(lái)連接具有并列關(guān)系的詞，短語(yǔ)或句子。常見的并列連詞有：(1)表并列關(guān)系的and,both…and,notonly…butalso,neither…nor等。(2)表選擇關(guān)系的or,either…or等。(3)表轉(zhuǎn)折關(guān)系的but,while等。(4)表因果關(guān)系的for,so等。2.從屬連詞從屬連詞用來(lái)引導(dǎo)從句。常見的從屬連詞有：(1)引導(dǎo)時(shí)間狀語(yǔ)從句的after,before,when,while,as,until,till,since,assoonas等。(2)引導(dǎo)條件狀語(yǔ)從句的if,unless等。(3)引導(dǎo)原因狀語(yǔ)從句的because,as,since等。(4)引導(dǎo)目的狀語(yǔ)從句的sothat,inorderthat等。(5)引導(dǎo)讓步狀語(yǔ)從句的though,although,evenif等。(6)引導(dǎo)結(jié)果狀語(yǔ)從句的sothat,so…that,such…that等。(7)引導(dǎo)比較狀語(yǔ)從句的than,as…as等。(8)引導(dǎo)名詞從句的that,if,whether等。3.常用連詞的用法辨析（1）while,when,as這三個(gè)連詞都可引導(dǎo)時(shí)間狀語(yǔ)從句，但用法有所不同。1)當(dāng)某事正在進(jìn)行的時(shí)候，又發(fā)生了另一件事。While,when,as都可用來(lái)引導(dǎo)表示“背景”的時(shí)間狀語(yǔ)從句。例如：As/When/WhileIwaswalkingdownthestreet,Inoticedapolicecar.2)當(dāng)兩個(gè)長(zhǎng)動(dòng)作同時(shí)進(jìn)行的時(shí)候，最常用的是while。例如：Whilemotherwascookinglunch,Iwasdoingmyhomework.3)當(dāng)兩個(gè)動(dòng)作都表示發(fā)展變化的情況時(shí)，最常用的是as。例如：Aschildrengetolder,theybecomemoreandmoreinterestedinthingsaroundthem.4)當(dāng)兩個(gè)短動(dòng)作同時(shí)發(fā)生時(shí)，或表示“一邊…一邊…”時(shí)，最常用as。例如：Justashecaughtthefly,hegavealoudcry.Shelookedbehindfromtimetotimeasshewent5)當(dāng)從句的動(dòng)作先于主句的動(dòng)作時(shí)，通常用when。例如：Whenhefinishedhiswork,hetookashortrest.6)當(dāng)從句是瞬間動(dòng)作，主句是延續(xù)性動(dòng)作時(shí)，通常用when。例如：WhenJohnarrived,Iwascookinglunch.（2）as,because,since,for這四個(gè)詞都可表原因，但用法有區(qū)別。1)如果原因構(gòu)成句子的最主要部分，一般用because。因此，because引導(dǎo)的從句往往放在句末。例如：Istayedathomebecauseitrained.---Whyaren’tyougoing?---BecauseIdon’twantto.2)如果原因已被人們所知，或不如句子的其它部分重要，就用as或since。Since比as稍微正式一點(diǎn)。As和since引導(dǎo)的從句一般放在句子的開頭。例如：Ashewasn’tready,weleftwithouthim.SinceIhavenomoney,Ican’tbuyanyfood.3)for用來(lái)補(bǔ)充說(shuō)明一種理由，因此，for引導(dǎo)的從句幾乎可以放在括號(hào)里。For引導(dǎo)的句子不放在句子的開頭。例如：Idecidedtostopandhavelunch----forIwasfeelingquitehungry.（3）if,whetherif和whether都可作“是否”講，在引導(dǎo)賓與從句是一般可互換。例如：Iwonderwhether(if)youstillstudyinthatschool.Idon’tknowwhether(if)helikesthatfilm.在下列情況下，只能用whether,不能用if：1)引導(dǎo)主語(yǔ)從句時(shí)。例如：Whetherhewillcometothepartyisunknown.2)引導(dǎo)表語(yǔ)從句時(shí)。例如：ThequestioniswhetherIcanpasstheexam.3)在不定式前。例如：Ihaven’tmadeupmymindwhethertogothereornot.（4）so…that,such...that1)so…that中的so是個(gè)副詞，其后只能跟形容詞或副詞，而such...that中的such是個(gè)形容詞，后接名詞或名詞短語(yǔ)。例如：I’msotiredthatIcan’twalkanyfarther.Itwassuchawarmdaythathewentswimming.2)如果在名詞之前有many,much,little,few時(shí)，用so,不用such。例如：Hehassolittleeducationthatheisunabletogetajob.IhavehadsomanyfallsthatIamblackandblueallover.（5）either…or…,neither…nor,notonly…butalso…這三個(gè)連詞詞組都可連接兩個(gè)并列成分。當(dāng)它們連接兩個(gè)并列主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞要隨相鄰的主語(yǔ)變化。例如：Eitheryouorheiswrong.Neitherhenorhischildrenlikefish.Notonlytheteacherbutalsothestudentswanttobuythebook.（6）although,but這兩個(gè)連詞不能用在同一個(gè)句子中。例如：我們不能說(shuō)“Althoughheisoversixty,butheworksashardasothers.”這個(gè)句子應(yīng)改為：Althoughheisoversixty,heworksashardasothers.或Heisoversixty,butheworksashardasothers.（7）because,so這兩個(gè)連詞同樣不能用在同一個(gè)句子中。例如：我們不能說(shuō)“BecauseJohnwasill,soItookhimtothedoctor.”這個(gè)句子應(yīng)改為BecauseJohnwasill,Itookhimtothedoctor.或Johnwasill,soItookhimtothedoctor.【實(shí)例解析】1.---Ilikeridingfast.It’sveryexciting.---Oh!Youmustn’tdoitlikethat,________itmayhaveanaccident.A.andB.orC.soD.but答案：B。該題考查的是并列連詞的用法。答語(yǔ)的意思是“你不要那樣做，否則會(huì)發(fā)生事故的?！痹谶@四個(gè)并列連詞中，只有or含有這樣的意思，所以應(yīng)選B。2.Johnfellasleep________hewaslisteningtothemusic.A.afterB.beforeC.whileD.assoonas答案：C。該題考查的是引導(dǎo)時(shí)間狀語(yǔ)從句的常用從屬連詞的用法。本句的含義是“約翰在聽音樂(lè)的時(shí)候睡著了。”表示在干某事時(shí)發(fā)生了某個(gè)事情”通常用while。因此應(yīng)選C。【中考演練】二.用適當(dāng)?shù)倪B詞填空1.______theyarebrothers,theydon’tlooklikeeachotheratall.2.Thedresswasveryexpensive,______Ididn’tbuyit.3.---Doyouknow______Icouldpasstheexam?---Sorry,I’venoidea.4.Mr.BrownknowslittleJapanese,______hecan’tunderstandtheinstructionsonthebottleofthepills.5.Thewarwasoveraboutayearago,______theAmericansoldiersinIraqarestillhavingalotoftroubletodealwith.6.---IsDavidatschooltoday?---No.Heisathome_______hehasabadcold.7._____Lily_____Lucymaygowithyoubecauseoneofthemmuststayathome.8.Studyhard,_____youaresuretohaveagoodresultintheexam.9.Pleasehaveawash_______yougotobed.10.Thetwinshavelearnedalot______theycametoChina.三.初三英語(yǔ)中考專題復(fù)習(xí)-連詞
