精选优质文档-倾情为你奉上初中英语语法连词教学目标:掌握连词的用法,在写作中能够灵活运用。 教学重点:1、并列连词的用法 2、 从属连词的用法 3、 相似连词的辨析教学难点:连词之间的意义及辨析(一)连词概述连词是连接单词、短语或句子的一种虚词。在句中不单独作句子成分。历年中考中常考并列连词and,but,neither nor;从属连词now that,though,when。所以了解状语从句和宾语从句的真正意义有助于正确使用从属连词。(二)基础知识梳理1并列连词用来连接彼此并列的词、短语或句子。并列连词有and,or,but,so,for,nor等。2关联连词有bothand,either or,neithernor,not onlybut also,as well as,as much as等。3连接性副词有however,therefore,besides,yet,anyway,still,all the same等。4并列连词和连接性副词存在以下的区别:1)连接两个独立的分句时,并列连词的位置只能放在它所引导的分句的句首,前面通常有逗号。如:I must work hard, for I still have a long way to go.They all went, but I didn't go.2)连接性副词的位置比较灵活,句中、句首、句末都可以。但是放在句首较为普遍。如:Mother was ill, therefore, she stayed at home yesterday.= Mother was ill, she therefore, stayed at home yesterday.= Mother was ill, she stayed at home yesterday, therefore.3)两个并列连词不可以连用。如:He tried hardand but he failed to get the job.此句中的but应改为yet。因为and和but都是连词。5从属连词是用来引导从句,如宾语从句、状语从句、定语从句等。从属连词有that, if, unless, whether, who, whose, what, which, where, than, when, while, as, since, though, although, because, before, after, until, as soon as, now that, so.that, so that, as. as,(not) as/soas 如:If it snows tomorrow,we won't go on a picnic.(If引导条件状语从句)Could you tell me whose PC it is? (whose引导宾语从句)The man who is talking to my class teacher is my father.(who引导定语从句)连词的功能用来连接词,短语,从句或句子的词叫连词。连词是一种虚词,在句中不能单独使用。连词可分为两类:并列连词和从属连词。5. 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等。(4)表因果关系的for, so等。6. 从属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 , whether等。7. 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 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。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:As 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, whetherif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.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.that1) sothat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。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, 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: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 John was 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.【现场练兵】I.选择填空( )1.
