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
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
连词和状语从句 26．(2015·江苏高考)It is so cold that you can't go outside ________ fully covered in thick clothes. A．if B．unless C．once D．when 解析：选B考查状语从句。句意：天太冷，你不能去外面，除非你全裹在厚衣服里。unless相当于if ... not (如果……不)，符合句意。if“如果”；once“一旦”；when“当……的时候”，都不符合语意逻辑。________ fully covered in thick clothes为状语从句的省略，补充完整为“unless you are fully covered in thick clothes”。 33．(2015·湖南高考)________ the job takes a significant amount of time, most students agree that the experience is worth it. A．If only B．After C．Although D．In case 解析：选C考查状语从句。句意：虽然这份工作要花大量的时间，但大多数学生都同意这次经历是值得的。句中的a significant amount of time与worth it之间构成对比，故用although引导让步状语从句。 20．（2015陕西高考）I believe you will have a wonderful time here ________ you get to know everyone else. A．though B．as if C．once D．so that 解析：选C考查状语从句。句意：一旦你认识了这里的其他所有人，我相信你会在这里玩得很愉快的。根据句中的关键信息you will have a wonderful time和you get to know everyone else，可知应用once引导时间状语从句。 31．（2015福建高考）________ the students came from different countries, they got along quite well in the summer camp. A．While B．Unless C．Since D．Until 解析：选A考查状语从句。句意：尽管学生们来自不同的国家，他们在夏令营相处得非常好。根据句意可知，本题前后为转折关系，所以应用while“尽管”来引导状语从句。 34．(2015·安徽高考)________he once felt like giving up, he now has the determination to push further and keep on going. A．Where B．As C．In case D．Now that 解析：选A考查连词。句意：在他曾经想放弃的地方，现在他有决心前行，并继续走下去。where 在这里是连词，意为“(在)……的地方”，符合语境。 23．(2015·安徽高考)________scientists have learned a lot about the universe, there is much we still don't know. A．Once B．Since

【专题四】介词、连词与状语从句 【考情分析】 介词 1．常见介词的用法及辨析。 2．介词与其他词性所构成的一些短语。 3．在定语从句中，介词的使用情况。 连词 1. 考查并列连词、从属连词的用法 2.重点考查主从复合句和并列句的连接词的选用。 状语从句 1.状语从句的分类 1.可分为时间、原因、地点、目的、结果、条件、让步、比较及方式等类型。 2.状语从句的引导词与介词的用法比较；状语从句与定语从句引导词的辨析。 3.能够辨别同类状语从句中近似连接词的用法差异。 【知识归纳】 介词： 1.“名词＋介词”型 the key/answer/visit/apology/introduction/way…to； wish/desire/prize/respect…for； pity/mercy/congratulation/effect/advice/impression/influence…on 2.“介词＋名词”型 (1) in ＋名词 in advance 在前头，事先，预先in case 如果，万一in charge 主管，掌管，看管 in common 共有，共同，公有in demand 有需要的in doubt 感到疑惑的，难以确定的 (2)①on＋名词 on guard 在值勤on leave 在休假on holiday在度假on strike罢工on sale出售on loan 借贷 ②on＋the＋名词on the move 在移动，搬迁；离开on the march 在行军on the flow 在涨潮 (3) beyond ＋名词 beyond one's power 是某人力所不及的beyond one's reach 够不着 beyond description 难以形容beyond words 无法用语言形容beyond doubt 无疑 (4) under ＋名词 under development 在发展中under observation 在观察中under test 在测试中 under construction 在建设中under examination 在检查(调查)中under consideration 在考虑中 (5) at ＋名词 at length 详细地，长时间at sea 茫然at will 任意地at work 在上班at lunch 在吃午饭 at rest在休息at table 在吃饭at school 上学at church 做礼拜at peace 处于和平状态 (6) out of ＋名词 out of breath 上气不接下气out of balance 失去平衡out of date 过时out of patience 不耐烦 3．“动词＋介词”搭配 ①rob sb. of sth. ; supply us with food ;make a desk of wood ; make bread from flour ②介词＋the ＋部位与动词的关系(＝动词＋sb.’s ＋部位，可换用) strike him on the head(“击，拍，碰，摸”意义与on连用) catch him by the arm(“抓，拉，拿，扯”意义与by连用) 注意：同一介词与不同动词搭配，意义各异的情况。 reply to the letter回信，sing(dance)to the music和音乐唱(跳)，amount to 达到，加起来有……，devote to把……贡献给，drink to为……干杯，object to反对，look forward to 渴望，come to苏醒，belong to属于，search for搜……，ask...for...寻找，use...for用作，leave for前往，take...for 误以为， 4．“形容词＋介词”型 at前的adj.：angry, good, bad, surprised, excited, puzzled等。 of前的adj.：afraid, sure, certain, full, tired, fond, proud, worthy等。worthy of值得的；proud of(take pride in)自豪；sure of / about确信；fond of喜欢；full of充满 with前的adj.: angry, strict, busy, careful, popular, patient等。satisfied with (by)满意；busy with sth.(in doing sth.)忙着干某事；wrong with不对 in前的adj.：strict, weak, interested, successful, rich等。 to前的adj.：polite, kind, cruel, rude, close, available等。similar to相似for前的adj.：sorry, famous, fit, unfit, eager, anxious，(be) hungry/thirsty 等。grateful for sth. to sb.为某事感激某人；fit for适合；ready for准备from前的adj.：far, different, free, safe等。free from没有……(免除……)；far from离……远 about前的adj.：worried, anxious, careful，curious等。glad about sth. for sb.为某人某事高兴 5．复杂介词型 (1) 表示原因(通常在句中作状语), 意为“由于，因为”。 because of：表示实际原因(表达一种较强的因果关系)；on account of：常用来引述逻辑、理性和事实因素。 (2) 表示“除……之外”。 with the exception of＝except, except for“除……之外”； apart from (＝美式英语中的aside from)是个复合介词，既可表示“除……之外”，相当于except (for), 又可以表示“除……之外，(还，也)”，相当于besides；in addition to“除……之外(还，也)”，相当于besides。(3) 表示“有关，关于”。 concerning=regarding“关于，就……而论，在……方面”；with respect to“关于，就……而言”； as for和as to用于句首时表示“至于”。 (4) 表示“在……之前”。 ahead of=in advance of，可表示“(在空间或时间上比某人或某事物)更前，更早”，还可表示“领先，优于”； in front of 多指空间的前后关系，“在……前方”。 (5) 表示“支持，赞成”。 in support of 维护，支持，支援；in favor of 可指某人“支持，赞成”，也可指事物“有利于……”。 (6) 表示“鉴于，由于；根据，按照”。 in the light of 按照，考虑到in terms of 就……而言，谈到according to 根据；按照 in view of 鉴于，因为 (7) 表示“尽管”。 in spite of 尽管，不管 连词 连词分为并列连词和从属连词两大类。并列连词是连接主语与主语，谓语与谓语，句子与句子，分词与分词的词，它要求前后两部分有相同的形式和语法作用；而从属连词一般连接主句与从句，从句形式有名词性从句，定语从句和状语从句等。 1．并列连词 并列连词可用来连接词与词，词组与词组，分句与分句。常用的并列连词有：and(和)，as well as(既……又)，both... and(不但……而且)，not only... but also(不但……而且)，not ...but(不是……而是)，neither...nor(既不……也不)，either... or(不是……就是)，or(或者)，but (但是)，yet(然而)，for(因为)，so(所以)，while(而)，when(这时)等。如：Both my brother and my sister are teachers./ His room is bright but mine is gloomy(暗沉沉的)．/ He can not only repair radios but also fix them./ It is a glorious(光荣的)yet difficult task./ Strike while iron is hot. 2．从属连词 从属连词是指在复合句中引导从句的连结词。常见的从属连词有：(1)引导时间状语从句的：after, before, when, as, while, since, until, till, as soon as (2)引导原因状语从句的：because, since, as (3)引导让步状语从句的：although, though, no matter(无论), even if (though) (4)引导条件状语从句的：if, unless, once, so (as) long as (5)引导结果状语从句的：so... that..., such...that...

(9)引导主语，宾语或表语从句的连词主要有：that, whether, if三个。其中that 和whether间或还可以引起同位从句和状语从句。 3.几组容易混淆的并列连词： (1)and, or和but I must work hard, or I'll fail in the contest. Make up your mind, and you'll get the chance. —Would you like to come to dinner tonight? —I'd like to, but I'm too busy. (2)not only...but (also), as well as不但……而且 She plays not only the piano, but (also) the guitar. Not only does he like reading stories, but also he can even write some. (3)neither...nor “既不……也不……”；both...and...“两者都”；either...or...“不是……就是……” Neither you nor he is to blame. Either you or I am right. (4)not...but... 不是……而是…… They were not the bones of an animal, but the bones of a human being. (5)for 因为 He is absent today, for he is ill. 注意：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。 (6)so, therefore因此 He hurt his leg, so he couldn't play in the game. 状语从句： （一）时间状语从句 时间状语从句 1．when, while, as的区别 这三个词都可以用作连接词，表示时间关系，但有所区别。 (1)when表示时间关系时，意思常常是“当(在)……的时候”。主句和从句中的动作或事情可以同时发生，也可以先后发生。例如： When we were at school, we went to the library every day. 我们在求学的时候，每天都到图书馆去。 (2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，主句中的动作或事情在从句中的动作或事情的进展过程中发生。它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。如上面第一个例句中的when，可以用while代替；而第二个例句中的when，就不能用while代替。例如： Please don’t talk so aloud while others are working. 别人在工作的时候，请勿大声讲话。 (3)as用作连接词表示时间关系时，意思也是“当(在)……时候”，往往可与when或while通用，但它着重指主句和从句中的动作或事情相并发生。例如： I saw him as he was getting off the bus.当他下公共汽车的时候，我看见了他。 2．一些表示时间的名词短语也可用来引导时间状语从句 the minute, the moment, the instant, every time, the last time, every time。如：

Although it was snowing, (yet) it was not very old. I was late for the last train although I hurried. 2)as “虽然、、、但是，纵使、、、”（需将形容词、副词、名词、动词等放在句首，
