►专题06连词 考点精讲 一、连词的概念 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。 二、连词的分类 连词主要可分为2类：并列连词和从属连词。 并列连词用来连接平行的词、词组和分句。如：and, but, or, nor, so, therefore, yet, however, for, hence, as well as, both…and, not only…but also, either…or, neither…nor, （and）then等等。 专门连接主句和从句的连词，叫作“从属连词”。从属连词主要用在状语从句、定语从句和名词性从句中。 三、连词的具体用法 （一）并列连词 并列连词，起并列、连接作用的，并且它连接着的是有着同等语法地位的单词、词组或者句子。 1.表并列关系 （1）and ①和；并且，用于肯定句 She can dance and play the piano. They started to dance and sing ②用于祈使句+，+and+将来时的句子 Come early，and you will see her. （2）Both...and... 两者都 Both my daughter and my son like reading books.  （3）not only...but （also）...不但......而且（谓语动词就近一致） She plays not only the piano, but （also） the guitar. 她不但弹钢琴，也弹吉他。 注意：not only...but also 关联两个分句时，一个分句因有否定词not 而必须倒装。 Not only does he like reading stories, but also he can even write some. （4）as well as也；和（谓语动词，就远原则） She,as well as her friends likes playing basketball. （5）neither...nor... 既不......也不...... 谓语动词采用就近原则，与nor后的词保持一致。 Neither you nor he is to blame. 你和他都不该受指责。 2.表转折关系 （1）but 但是表示转折 I like English but I can't speak it well. （2）yet 然而 I made breakfast yet my daughter didn't eat it. （3） while 然而，表示对比。 Some people love cats, while others hate them （4） however,然而，但是，常用逗号与其他隔开。 She has the window open, however cold it is outside （5） still 然而，还 Shes still learning to read. 3.表示选择关系 （1）or ①和；并且 用于否定句 She can’t read and write.(她既不会看书，也不会写字。） ② 或者 She likes going out with friends or playing outdoor games. ③ 否则 Don't be late for school,or i will punish you. （2）Either...or...或者......或者......（谓语动词，就远原则） Either you or I will win the prize. 4.表示因果关系 （1）so 所以 I am busy, so I can't go to the movies with you tonight. （2） for 因为 We rarely stay in hotels, for we can’t afford it. （3）  Therefore, I won't go to the movies with you tonight. I am busy. Therefore, I won't go to the movies with you tonight. （2） 从属连词 从属连词用是连接主句和从句。 1.引导名词性从句 that, whether可以引导主语从句、宾语从句、表语从句和同位语从句； if一般引导宾语从句，引导主语从句时只能用it作形式主语； because、as if等连词引导表语从句。 Whether it turns out to be a good idea or a bad idea, we'll find out.（主语从句） Can you tell me if he can come to my birthday party?（宾语从句） He said that he would one day get out of jail.（宾语从句） She seemed as if she knew me.（表语从句） The news that our team has won is known by all.（同位语从句） 2. 引导状语从句 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。 如：When you arrive, ask for Jane (2) 引导条件状语从句的if, unless等。 We can go to the zoo if our father come back on time (3) 引导原因状语从句的because、since、as、now that等。 Since you know all about it, tell me please. (4) 引导目的状语从句的in order that、so that、in case等。 In order that we can arrive there on time, we should start off early. (5) 引导让步状语从句的although、though、as、even if、even though等。 He went to school though/although he was very ill. (6) 引导结果状语从句的so that, so…that, such…that等。 He was so tired that he couldn’t go on any longer. (7) 引导地点状语从句的从属连词主要有where、wherever You shouldn’t go where you are not asked to. 四、常用连词的用法辨析 （一）while, when, as 这三个连词都可引导时间状语从句，但用法不一样。 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。 As/When/While I was walking down the street I noticed a police car. 2. 当两个较长动作同时进行的时候，最常用的是while。 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。 As children 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。 She looked behind from time to time as she went. 5. 当从句的动作先于主句的动作时，通常用when。 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when. When John arrived I was cooking lunch. （二）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。 I stayed at home because it rained.因为下雨，所以我呆在家里。 ---Why aren’t you going? ---Because I don’t 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。 As he wasn’t ready, we left without him. Since I have no money, I can’t buy any food. 2. 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。 I decided to stop and have lunch -for I was feeling quite hungry. （三）if, whether if和whether都可作“是否”讲，在引导宾与从句是一般可互换。 I wonder whether (if) you still study in that school. I don’t 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。 Whether he will come to the party is unknown. 2. 引导表语从句时。 The question is whether I can pass the exam. 3. 在不定式前。 I haven’t made up my mind whether to go there or not. （四）so...that, such...that 1. so…that中的so是个副词，其后只能跟形容词或副词，而such...that中的such是个形容词，后接名词或名词短语。 I’m so tired that I can’t walk any farther. It was such a hot day that he went swimming. 3. 如果在名词之前有many, much, little, few时，用so,不用such。 He has so little education that he is unable to get a job. （五）either...or..., neither...nor, not only...but 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。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. （六）although, but 这两个连词不能用在同一个句子中。 Although he is over sixty, but he works as hard as others.（×） Although he is over sixty, he works as hard as others.（√） He is over sixty, but he works as hard as others.（√） （七）because, so 这两个连词同样不能用在同一个句子中。 Because John was ill, so I took him to the doctor.（×） Because John was ill, I took him to the doctor.（√） John was ill, so I took him to the doctor. （√） （八）till/until，not...till/until 前者表示一个延续性的动作,后者表示一个才开始的动作。 I will stay here and watch the baby until you return.(stay这个动作一直进行到你return) They won’t go on working until they get what they think is reasonable.（他们要到获得了他们认为合理的东西时才会继续干下去的）   另外till与until基本可以互换,但是在句首时只能用until,不能用till. Until the last minute of the match we kept playing. Not until he had finished his work did he go home. （九）though，although 两个词都表示“虽然”,均不可以与but同时使用,但在句中可加still或yet连用。 although“尽管、虽然”仅作连词,比较正式,一般可以换为though； though“虽然、尽管、即使”,还可以与even连用(=even if),表示“即使、纵然”,作副词时意思是“然而、不过”,不能放在句首。 He passed the exams although illness prevented him from going to classes. she won’t leave the TV set, even though her husband is waiting for her for the supper. It was a quiet party. I had a good time, though. （十）prefer to...rather than...，prefer...to... prefer to...rather than...后面都是用动词原形, prefer...to...都是用动名词或名词。 I prefer English to Japanese. I prefer to learn English rather than learn Japanese. 原创精品资源学科网独家享有版权，侵权必究！学科网（北京）股份有限公司9 学科网（北京）股份有限公司 $$
