高考英语一轮复习知识点教案：连词

连词定义：连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。分类：根据在句中所起的作用，连词主要可分为并列连词和从属连词两类。

并列连词：连接具有并列关系的词、短语或句子的连词叫作并列连词。根据意义，它又可分为表示联合、转折、选择和因果等四种关系的连词。一、表示联合关系的并列连词表示联合关系的并列连词有：and,both…and,neither…nor,notonly…butalso,aswellas(除……外……也……)等。eg:Iamateacherandheisadoctor.Hehasbothexperienceandknowledge.NeitherInorhehasseenthefilm.Hehasexperienceaswellasknowledge.Hehasnotonlyexperiencebutalsoknowledge.二、表示转折关系的并列连词表示转折关系的并列连词有but,while(然而),yet(可是),however(然而，但是)，nevertheless(然而，不过)等。eg:Iamsorry,butIwon’tbeabletocometonight.Iamwilling,yetunable.我心有余而力不足。Heisshort,whilehisyoungerbrotheristall.Heworkedhard.However,hefailed.他很努力，然而还是失败了（however可置于句首、句中或句末）另外：副词still也能表示转折关系Thepainwasbad,stillhedidnotcomplain.虽然疼得厉害，可是他没有呻吟。三、表示选择关系的并列连词表示选择关系的并列连词有or(或),orelse(否则),either…or…(或……或……，不是……就是……)。eg:JohnorIamtoblame(责备).Seizethechance,orelseyouwillregretit.(orelse常置于祈使句后面)Youcaneitherstayathomeorgofishing.另外：副词otherwise,ratherthan也能表示选择关系Seizethechance,otherwiseyouwillregretit.Hewentratherthanstayasanunwelcomeguest.四、表示因果关系的并列连词表示因果关系的并列连词有so,for等。eg:Itwaslate,soIwenthome.Itismorning,forthebirdsaresinging.另外：副词then(那么，因而),thus(因此),therefore(因此，所以)常放在句首表示因果关系。Hewasbusy,thereforehecouldnotcome.Hestudiedhard,thushegotafullmark.从属连词：用来连接主句和从句的连词叫从属连词。从属连词可分为引导名词性从句的从属连词和引导状语从句的从属连词两类。引导名词性从句的从属连词引导名词性从句的从属连词有连接词that,whether和if,这些连接词在句子当中不充当任何句子成分；连接代词主要有who,whom,whose,which,what等，它们在句中可作主语、宾语、定语等；连接副词主要有when,where,why,how等，它们在句中作状语。Whowillattendthemeetinghasn’tdecidedyet.Weknow(that)theearthgoesaroundthesun.Iwonderifhehasreceivedmye-mail.Thatiswhyhedidn’tcometoschool.Thenewsthatourteamhadwonwasveryexciting.引导状语从句的从属连词一、引导时间状语从句的从属连词when,while,as,after,before,since,till/untill,once,assoonas,themoment/instant,nosooner...than...,hardly...when...等eg:Onceyoubegin,youmustgoon.Whenitrains.Igotoschoolbybus.Hardlyhadwefinishedtheworkwhenitbegantorain.二、引导地点状语从句的从属连词where,wherever等eg:Wherethereisawill,thereisaway.Wherevershemaybe,shewillbehappy.三、引导原因状语从句的从属连词as,since,because等eg:Hedidn’tgotoschoolbecausehewasill.Sinceeverybodyishere,let’sbegin.四、引导结果状语从句的从属连词so...that/such...that(如此......以致),so(结果)，that(以致),sothat(结果)等eg:Heissuchgoodstudentthatwealllikehim.Itwasverycold,sothatthewaterinthebowlfroze.五、引导条件状语从句的从属连词if,unless,so/aslongas,incase(如果，万一)等eg:Hewillnotcomeunlessheisinvited.Youwillbelatefortheclassifyoudon’thurry.六、引导目的状语从句的从属连词so(以便),sothat(为了),inorderthat(为了),less、incase(以防，免得)等eg:Shetookmedicineontimeinorderthatshemightgetwellsoon.七、引导让步状语从句的从属连词though/although,as(虽然),evenif/eventhough(即使),however,whatever,whoever,nomatterhow/what/which等eg:Oldasheis,hestillworkshard.Thoughheisold,hestillworkshard.Evenifyouwerehereyesterday,youcouldn’thelphim.八、引导方式状语从句的从属连词as(正如),asif/asthough(好像，似乎)等eg:Themancarriedtheboxawayashewastold.HespeaksEnglishasifhewereanEnglishman.九、引导比较状语从句的从属连词as(如……),as...as...,notso/as...as...,than等eg:Heworksharderthanbefore.Hiselderbrotherisastallashismother.并列连词与并列结构

一、and

判断改错：

(错)Theysatdownandtalkaboutsomething.

(错)Theystartedtodanceandsang.

(错)Isawtwomensittingbehindandwhisperthere.

(对)Theysatdownandtalkedaboutsomething.

(对)Theystartedtodanceandsing.

(对)Isawtwomensittingbehindandwhisperingthere.

解析：

第一句：and连接两个并列的谓语，所以talk应改为talked。

第二句：and连接两个并列的动词不定式，第二个不定式往往省略to，因此sang应改为sing。

第三句：and连接感观动词saw后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。

注意：and还可以和祈使句或名词词组连用表示条件。（or也有此用法）

Makeupyourmind,andyou'llgetthechance.

=Ifyoumakeupyourmind,you'llgetthechance.

Onemoreeffort,andyou'llsucceed.

=Ifyoumakeonemoreeffort,you'llsucceed.

二、比较and和or

1)并列结构中，or通常用于否定句，and用于肯定句。

2)但有时and也可用于否定句。请注意其不同特点：

Thereisnoairorwaterinthemoon.

Thereisnoairandnowateronthemoon.

在否定中并列结构用or连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。

典型例题

---Idon'tlikechicken___fish.

---Idon'tlikechicken,___Ilikefishverymuch.

A.and；andB.and；butC.or；butD.or；and

答案C。否定句中表并列用or,but表转折。

判断改错：

(错)Wewilldiewithoutairandwater.

(错)Wecan'tlivewithoutairorwater.

(对)Wewilldiewithoutairorwater.

(对)Wecan'tlivewithoutairandwater.

三、表示转折或对比

but表示转折，while表示对比

Somepeoplelovecats,whileothershatethem.

典型例题

---Wouldyouliketocometodinnertonight?

---I'dliketo,___I'mtoobusy.
