6、能单独使用。连词可分为两类：并列连词和从属连词。,连词的应用一、并列连词,并列连词用来连接具有并列关系的词，短语或句子。常见的并列连词有：1.表并列关系的and,bothand,not onlybut also,neithernor等。2.表选择关系的or,eitheror等。3.表转折关系的but,while（然而）等。4.表因果关系的for,so等。,注意事项,1.and:“和”在肯定句中表并列；or:“和”在否定句中表并列另外：1)or“或者”用于选择疑问句 2)or“否则”eg.Which do you like better,tea or milk?.Hurry up,or youl
7、l be late for school.2.but“但是”表转折eg.I listened,but I heard nothing.注意：1)though(虽然),but(但是)不能连用 2)not but 不是而是eg.This book isnt mine but yours.3.both and:既又（连接主语为复数）neithernor:既不也不 连接两主 eitheror:或者或者 语后者决 not only but also:不但而且 定单、复eg.1)Both he and I are students.2)Neither he nor I am a student.,二、从属
8、连词,从属连词用来引导从句。常见的从属连词有：(1)引导时间状语从句的after,before,when,while,as,until,till,since,as soon as等。(2)引导条件状语从句的if,unless等。(3)引导原因状语从句的because,as,since等。(4)引导目的状语从句的so that,in order that等。(5)引导让步状语从句的though,although,even if等。(6)引导结果状语从句的so that,sothat,suchthat等。(7)引导比较状语从句的than,asas等。(8)引导名词从句的that,if,whethe
9、r等。,常用连词的用法辨析1.while,when,as,这三个连词都可引导时间状语从句，但用法有所不同。1)当某事正在进行的时候，又发生了另一件事。While,when,as 都可用来引导表示“背景”的时间状语从句。例如：As/When/While I was walking down the street I noticed a police car.2)当两个长动作同时进行的时候，最常用的是while。例如：While mother was cooking lunch,I was doing my homework.3)当两个动作都表示发展变化的情况时，最常用的是as。例如：As chi
10、ldren get older,they become more and more interested in things around them.4)当两个短动作同时发生时，或表示“一边一边”时，最常用as。例如：Just as he caught the fly,he gave a loud cry.She looked behind from time to time as she went5)当从句的动作先于主句的动作时，通常用when。例如：When he finished his work,he took a short rest.6)当从句是瞬间动作，主句是延续性动作时，通常用
11、when。例如：When John arrived I was cooking lunch.,2.as,because,since,for,这四个词都可表原因，但用法有区别。1)如果原因构成句子的最主要部分，一般用because。因此，because引导的从句往往放在句末。例如：I stayed at home because it rained.-Why arent you going?-Because I dont want to.2)如果原因已被人们所知，或不如句子的其它部分重要，就用as或since。Since比as稍微正式一点。As和since 引导的从句一般放在句子的开头。例如：A
12、s he wasnt ready,we left without him.Since I have no money,I cant buy any food.3)for用来补充说明一种理由，因此，for引导的从句几乎可以放在括号里。For引导的句子不放在句子的开头。例如：I decided to stop and have lunch-for I was feeling quite hungry.,3.if,whether,if和whether都可作“是否”讲，在引导宾与从句是一般可互换。例如：I wonder whether(if)you still study in that school
13、.I dont know whether(if)he likes that film.在下列情况下，只能用whether,不能用if：1)引导主语从句时。例如：Whether he will come to the party is unknown.2)引导表语从句时。例如：The question is whether I can pass the exam.3)在不定式前。例如：I havent made up my mind whether to go there or not.,4.sothat,such.that,1)sothat中的so是个副词，其后只能跟形容词或副词，而such.
14、that中的such是个形容词，后接名词或名词短语。例如：Im so tired that I cant walk any farther.It was such a warm day that he went swimming.2)如果在名词之前有many,much,little,few时，用so,不用such。例如：He has so little education that he is unable to get a job.I have had so many falls that I am black and blue all over.,5.eitheror,neithernor
15、,not onlybut also,这三个连词词组都可连接两个并列成分。当它们连接两个并列主语时，谓语动词要随相邻的主语变化。例如：Either you or he is wrong.Neither he nor his children like fish.Not only the teacher but also the students want to buy the book.,6.although,but,这两个连词不能用在同一个句子中。例如：我们不能说“Although he is over sixty,but he works as hard as others.”这个句子应改为
16、：Although he is over sixty,he works as hard as others.或He is over sixty,but he works as hard as others.,7.because,so,这两个连词同样不能用在同一个句子中。例如：我们不能说“Because Johnwas ill,so I took him to the doctor.”这个句子应改为Because John was ill,I took him to the doctor.或John was ill,so I took him to the doctor.,用适当的连词填空,1.
17、_ they are brothers,they dont look like each other at all.2.The dress was very expensive,_ I didnt buy it.3.-Do you know _ I could pass the exam?-Sorry,Ive no idea.4.Mr.Brown knows little Japanese,_ he cant understand the instructions on the bottle of the pills.5.The war was over about a year ago,_
