连词与状语从句知识梳理

连词与状语从句知识梳理 连词与状语从句知识梳理 知识梳理 知识点1: 一、连词含义 连词是一种虚词,不能担任一个句子成分。它主要是包括并列连词和从属连词。 二、具体用法 1. 并列连词 1). 并列连词的功能: 连词在句中主要起连接词与词、短语与短语及句子和句子的作用。即,连接两个平行的 成分或句子。 如:and, but, or, nor, so, therefore, yet, however, for, as well as, both… and, not only…but also, either…or, neither…nor, (and)then等等。 2). 并列连词的用法:表示连接两个共同概念 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: There is no air or water in the moon. There is no air and no water on the moon. 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 。 both …and 两者都(两者都强调,谓语动词为复数) not only…but (also),不但…而且(强调后者,就近原则)

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. neither …nor 意思为" 既不……也不……" (就近原则) Neither you nor he is to blame. as well as也 (强调前者,就远原则) The students as well as their class teacher like watching football matches very much. I have one of his plays as well as a few of his novels. 表示选择的并列结构 1) or意思为" 否则" 。 I must work hard, or I'll fail in the exam. 2) either…or 意思为" 或者……或者……" 。注意谓语动词采用就近原则。 Either you or I am right. 表示转折或对比 1) but表示转折,while 表示对比。 some people love cats, while others hate them. 2) not…but … 意思为" 不是……而是……" not 和but 后面的用词要遵循一致原则。 They were not the bones of an animal, but (the bones) of a human being. 表示因果关系 1) for for 是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间。 2) so, therefore

状语从句类型及相似连词的用法区别

一、状语从句分类及常用连词: 类别连词 状语从句when, whenever, while, as, before, after, since, till, once, as soon as,etc. 状语从句where,wherever 状语从句because, since, as, for, now that, etc. 状语从句so…that, so that, such…that, that, etc. 状语从句in order that, so that, that, etc. 状语从句if, unless, as(so)long as, etc. 状语从句though, although, even if, even though, however, whatever, as,etc. 状语从句as…as, so…as, than, etc. 状语从句as, as if, as though, etc. 二、相似连词的用法区别 1.when, while, as, while表时间,从句需用延续性动词,切不可用瞬间动词。 when表时间,从句既可以用延续性动词,又可以用瞬间动词。 as表时间,与when相似,但侧重强调主从句动作同点或同段进行。 when, while后可以接分词短语。 2.because, as, since, for 语气位置意义 because最强前或后“原因”;表客观因果关系;回答“”as较强前“由于”;把众人所知的事实当作理由since较弱前“既然”;就对方陈述的事实作为理由for最弱后“理由”;对某一事实进行推断的理由 注:上面所说的“前”,指从句在主句之前;“后”,指从句在主句之后。 3.so that, so…that, such…that so that“以便”、“结果”表目的和结果。注意:在从句中有情态动词表目的。无情态动词表结果。 so…that “如此的…以致于”表结果。该结构常见于: 1.so+形/副+that 2.so+形+a(an)+单数名词+that 3.so+manymuch+复数名词(不可数名词)+that such…that“如此的…以致于”表结果。该结构常见于: 1.such+a(an)+形+名词+that 2.such+形+复数名词/不可数名词+that

状语从句连词总结

状语从句连词总结 1 时间状语从句: when当……时候 while 当……时候(动词只能是延续性动词) as当……时候(经常表示一边……一边……) after/before在……之后/之前 until/till直到……(即某一持续性行为持续到某一时间点) since/ever since自从……(即子某一时间点以来,常用完成时态或完成进行时) 名词性短语the time the moment the minute the day the year the first/second time each time每次every time每次next time下次any time在任何时候whenever不管什么时候 by the time到……时候(即指到某一时间点为止,主句常用完成时态) 一……就……as soon as once immediately directly instantly 还没来得及……就……hardly……when no sooner……than as long as长达…… 非时间状语从句:动词ing形式;at……形式;on doing/on sth形式 2地点状语从句 where在哪里,在什么地方 wherever无论在哪里 anywhere无论何处everywhere 到处,处处nowhere 无处,任何地方都无 to/in/from the place(s)where或to/in/from any place where 3原因状语从句 because(语气最强)因为,多置于主句之后 as(语气最弱)因为,多置于主句之前 since语气较弱,常表示对方已知的事实,相当于“既然” now (that)既然 for the reason that因为(that引导的是同位语从句,先行词为reason) in that由于某种原因,多用于书面语 seeing that因为,鉴于 4目的状语从句 in order that以便 so (that)为了 for fear that惟恐,以防 in case以防万一有某种情况发生 5结果状语从句 so (that)所以 so……that……结构 such……that……结构

从属连词 状语从句

一、重点知识归纳及讲解 (一)从属连词 从属连词是引导状语从句,宾语从句及其他从句的连词。 1.引导状语从句的从属连词有: 1)when, while, before, after, as soon as, until, since等,引导时间状语从句。 2)because, as, since等引导原因状语从句。 3)if, as long as等引导条件状语从句。 4)though, although引导让步状语从句。 5)so…that…, such…that…等引导结果状语从句。 6)so that引导目的状语从句。 7)as?as?;than等引导比较状语从句。 2.常用从属连词的辨析 1)when, as, while when, as, while都表示“当…的时候”,但when引导的时间状语从句的动作和主句的动作可以是同时发生,也可以先后发生,when既可指时间点,也可指一段时间,所以既可引导一短暂动作动词,也可引导持续性动作的动词。 用as作从属连词引导时间状语时强调主句和从句的动作并行发生,不指先后,尤指短动作或事件同时发生。如:As I looked, someone came near.(正当我看的时候,有个人走上前来。)as还可说咱两种正发展或变化的情况,意为“随着”。如:As spring warms the earth, all flowers begin to bloom.(随着春回大地,百花开始绽放。)表示主从句动作同时,as意为“一边…一边…”。如:He hurried home, looking behind as he went.(他匆匆忙忙跑回家,一边走一边回头望。) while只指一段时间,从句中的谓语动词不能用终止性动词,强调某一段时间内主从句动作同时发生,常对同类的动作进行对比。如:While we were waiting for a bus, it was raining hearily.(我们在等车时,天正下着大雨。) 2)till和until till和until都表示“直到…为止”。主句用延续性动词,主句和从句都用肯定式:意为“直到…才”。主句用终止性动词,从句用肯定式,主句用否定式。until较till正式,until引导的时间从句可以放在句首。 例如: She won't go away till you promise to help her. 直到你允诺要帮助她,她才走开。 Until you told me, I had heard of nothing what happened. 直到你告诉我,我才知道发生了什么事。 3)since since引导的时间状语从句常用一般过去时,其主句一般使用现在完成时。 例如: Jim has been in the factory for two years since he left school. 从吉姆毕业起,他在这家工厂工作两年了。

高考必考语法精讲精练专题十一:并列句与状语从句(含解析)

高考必考语法精讲精练 语法专题十一:并列句与状语从句 状语从句是比较重要的语法项目。《2020年普通高等学校招生全国统一考试大纲》附录语法项目表中将状语从句列为必考项。全国卷新课标Ⅰ对状语从句的考查一般在完形填空、语法填空和短文改错中,主要考查从句引导词的用法。 2020年高考全国卷Ⅰ没有考查状语从句。 2020年高考全国卷Ⅰ第43题(完形填空)考查了状语从句引导词Since /Although /As /If 的选择。 2020年高考全国卷Ⅰ没有考查状语从句。 一、并列句 (一) 并列连词 ①They come from the same country,and they are good friends. ②I was glad to meet Jenny again, but I didn't want to spend all day with her.(2013·新课标卷Ⅱ) ③It must have rained last night, for it is wet all over. ④Yesterday, I forgot to pick my daughter up, so she waited in the kindergarten for nearly two hours. ⑤Would you like to leave or would you like to stay? 规律总结: 1.表示并列、顺承关系的并列连词有and。 2. 表示转折关系常用的并列连词有but, yet(然而), whereas(然而,但是), while(然而)等。3.表示因果关系的并列连词有for, so等。 4.表示选择关系常用的并列连词有or, either ... or ..., not ... but, neither ... nor ...等。 (二) 祈使句+and/or/otherwise句式 ①Work hard and you will succeed. =If you work hard, you will succeed. ②Hurry up or we will be late. =If you don't hurry up, we will be late. ③A few more efforts and you will succeed. =If you make a few more efforts, you will succeed. 规律总结: 1.祈使句+and+陈述句=If ...,+主句。 2.祈使句+or/otherwise+陈述句=If ... not ...,+主句。 二、状语从句 英语中状语从句总共有九类,分别用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是较复杂的语法项目,但是理解起来并不难。从本质上讲,状语从句就是利用不同的关联词语将几个分句连接起来,以表达分句之间的特定逻辑关系。例如: ①I have brought an umbrella because it is raining.(原因)

并列连词 when 和引导时间状语从句的从属连词 when 是不同的

并列连词when 和引导时间状语从句的从属连词when 是不同的。这主要表现在以下几个方面: 1. 位置:when 引导时间状语从句时,该从句可放在主句之前也可放在主句之后;而并列连词when 只能位于两个分句之间,而且前面常常有逗号。例如: Come when you please. 你高兴来就来吧。(when 为从属连词) When I saw him,he was writing to a friend of his. 我看见他时,他在给一个朋友写信。(when 为从属连词) I was taking a walk,when I came across him. 我正在散步,突然碰见了他。 2. 意义:when 作从属连词用时,它所引导的从句表示主句中谓语动词动作发生的时间,即作“当……时”解;而并列连词when 连接的两个分句中,第一个分句表示的是背景,第二个分句表示的是一种突然的、意想不到的情况或过早发生的事情。when 通常含“这时突然”之义。例如: I was thinking of this,when I heard my name called. 我正想着这件事,突然听到有人叫我的名字。 I had just fallen asleep,when the boor-bell rang. 我刚入睡,门铃突然响了起来。 这种意义在孤立的句子中可以理解到,在文章中更能体会得到。如在“I was wandering through the street when I caught sight of a tailor's shop ”一句中,“在街头漫步”只是“看见有家缝纫店”的时间,其后作者怎样走进缝纫店,想要什么样的衣服,怎样受到伙计的奚落,又怎样受到老板的奉承等情景均与“漫步街头”没有直接的因果关系。 3. 时态:when 引导的时间状语从句中可以根据句意的需要用一般现在时、一般过去时、过去进行时、分别说明现在,过去,甚至将来的行为;并列连词when 后面的分句中通常用非延续性动词的一般过去时,其前表时间的分句中可用: (1 )过去进行时表示过去某时间正在进行的动作。例如: I was cooking when I heard her knocking at the door. 我正在做饭,突然听到她敲门的声音。 He was thinking about the problem,when an apple fell to the ground. 他正在思考这个问题,突然有一只苹果掉到了地上。 (2 )was /were going to,was / were about to,was / were on the point of 表示过去某一时间将要发生的动作。例如: I was just going when he came in. 我正要走,这时他就进来了。 We were about to start when it began to rain. 我们刚要动身天就开始下起雨来了。 He was on the point of leaving,when someone knocked at the door. 他刚要走就有人敲门。( 3 )过去完成时表示过早发生的事情。请看下述两种场合:(a )过去完成时和含否定意义的hardly,scarcely,nearly 连用,和just,little 连用,或者与否定词not 连用时,表示“刚……,就……”的意思。例如: I had hardly opened the door when he hit me. 我刚一开门他就打了我一下。 I had nearly reached the town,when the young man suddenly said very slowly,“Do you speak English?”我快要进城了,年轻人突然慢慢地说:“你会讲英语吗?”
