并列连词与并列结构 并列连词引导两个并列的句子。 1)and 与or 判断改错： (错) They sat down and talk about something. (错) They started to dance and sang. (错) I saw two men sitting behind and whisper there. (对) They sat down and talked about something. (对) They started to dance and sing. (对)I saw two men sitting behind and whispering there. 解析：第一句：and 连接两个并列的谓语，所以talk 应改为talked。 第二句：and 连接两个并列的动词不定式，第二个不定式往往省略to，因此sang 应改为sing。 第三句：and 连接感观动词saw 后面的用作的宾补的两个并列分词结构，因此whisper 应改为whispering。 注意：and 还可以和祈使句或名词词组连用表示条件。（or也有此用法） Make up your mind, and you'll get the chance.= If you make up your mind, you'll get the chance. One more effort, and you'll succeed.= If you make one more effort, you'll succeed. 2)both …and两者都 She plays (both) the piano and the guitar. 3)not only…but (also), as well as不但…而且） She plays not only the piano, but (also) the guitar. 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)neithe…nor 意思为"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. neither…nor…一起用时，作为关联性的并列连词，连接语法功能相同的平行结构：Neither you nor he konws it. (连接用作主语的代词) The old man can neither read nor write. (连接动词) I drink neither coffee nor tea. (连接宾语) The story is neither interesting nor instructive. (连接用作表语的形容词) Gas is a substance with neither a definite volume nor a definite shape. (连接介词宾语) I believe neither what you said before nor what you are saying now. (连接宾语从句) 注意： (1)Neither置于句首时，neither…nor…所连接的分句均须主谓倒装： I don't like that girl. Neither have I dated her for a dance(约她跳舞) nor will I do so. Neither does he play the cello nor does his brother. (2)Neither…nor…连接主语时，后面的动词在数上应与靠近的主语取得一致： Neither Ike nor I am going to attend the meeting. (动词与靠近，故用am。) Neither Ike nor he is going to attend the meeting. (动词与he靠近，故用is。) (3)neither…nor…作“既不…也不…”解，故谓语动词必须用肯定式，不能用否定式
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” I had been there little more than a week when I set to work in earnest. 我到那儿还不超过一个星期就开始认真干起活来。 I had not been reading for half an hour when I heard steps outside.
并列连词用法归纳 并列连词有and、but、or、for、nor、so以及not only…but also…、both…and…、neither…nor…、either…or…、as well as等。 并列连词是构成英语并列句的桥梁，英语中两个或两个以上的互不依从的对等句子通常都是通过并列连词来体现的。现分类讲解如下： I．表示增补关系：这类并列连词通常是and、nor、so、both…and…、not only…but also…、neither…nor…、as well as…等。 1. and可用来连接两个或两个以上的单词、短语或句子，表示一种顺接的关系。如： My brother and I study in the same school. Our knowledge may come from the books and from practice. We are singing and they are dancing. 2. so表示肯定的增补，而neither、nor表示否定的增补，三者常位于句首，要求主谓倒装。例如： Tom got up at six this morning. So did Mike. 汤姆今晨六点钟起床，迈克也是。 He can’t swim, neither can Mary. 他不能游泳，玛丽也是。 3. both…and…可用来连接两个并列的主语、谓语、宾语、表语和状语等。当连接两个并列的主语时谓语动词通常用复数形式。如： Both Li Ping and Mary are going to the Great Wall tomorrow. He can both swim and skate. They speak both English and French. 4. not only…but also…、neither…nor…这两个并列连词和both…and…的共同特征是都连接两个相同的句法单位，如主语、谓语、宾语、表语和状语等。其不同之处主要是它们连接两个并列主语时谓语动词用就近原则。如：Not only the students but also the teacher gives the money to our school. 不仅学 生为我们学校捐了款而且这位老师也捐了款。 Neither he nor I am right. 他不对我也不对。 5. 注意not only…but also…强调的后者，而as well as…强调的是前者。当as well as…引导并列主语时，谓语动词与前面的主语保持一致。如：He as well as his students gets up at six o’clock. 不仅他的学生们而且他也是六点钟起床。 II．表示选择关系：这类并列连词通常是or、either…or…等。 1.这两个连词主要表示一种选择关系，注意的是either…or…通常引导两个相 同的句法单位，当连接两个并列主语时谓语动词用就近原则。如： He is either at home or at school. 他或者在家或者在学校。 Either he or I am wrong. 不是他错就是我错。
并列连词和从属连词 连词是一种虚词，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。连词主要可分为两类：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。 1. 并列连词并列连词用来连接属于同一层次并具有相同句法功能的词；短语或句子。并列连词包括：基本并列连词如and, or , but , 关联连词如either...or , neither...nor , not only...but also ,both ...and, whether...or 等；介于并列连词与从属连词之间的连词；介于并列连词与从属连词或介词之间的结构如as well as , as much as, rather than , more than, no less than 等；此外还有些'半连接词'，一些语法学家把它们称为连接副词，如nevertheless, however, meanwhile, otherwise, likewise 等，它们在句中做连接性状语。这类连词主要是从逻辑上，而不是从形式上连接句子，其关系比较松散。 1) 表示意义转折和对比的并列连词 常见的有：but , while, whereas, still, yet , nevertheless, likewise, anyway , only , conversely , on the contrary, by this time, all the same , fortunately, on the other hand , in the meantime 等词语。 2) 表示选择的并列连词 常见的有：or, whether...or, either...or, otherwise 等。例如： Either ...or 和whether...or 表示选择，其意义比单用or 要强，但由whetrher...or 构成的并列结构一般只能担任句子的从属成分。上例中最后一句，whether...or 结构在句中担任句子的从属成分。Either ...or 和or 一样，可以连接两个并列的独立分句，而whether...or 则不可以。or 用于表示否定的条件意义时，有时可与连用。 Or 连接主语时，如主语都是单数，动词则取单数形式；如主语都是复数，动词则取复数形式，如果主语有的是复数，动词则取复数形式，如果主语有的是单数，有的是复数，动词的数则与它靠近的主语的数相一致。 连接两个主语时，动词的数也应与靠近他的主语的数相一致。例如： Neither he nor I am a good student. 3) 表示因果意义的并列并列连词 常见的有：for ,so ,therfore ,hence ,thus, accordingly, consepuently, on that account, in that case 等。例如：The fuel must have beeenfinished, for the engine stopped. It rained , therefore the game was called off. 表示原因的并列连词只有for ，它所引导的分句只是对前一分句补充说明理由或推断原因。for 引导的分句只能置于句末，而且必须用逗号与前一分句隔开。上面所提到的so,therefore 等词，有的语法学家把它们做为连接性状语。 4) 表示联合关系的并列连词 常见的有：and, both...and, neither...nor, not only... but also 等。 当neither...nor, not only ...but also 连接主语时，动词的数则与靠近它的主语的数相一致。Both ...and 不能连接两个以上的并列成分，也不能连接分句。例如：误：Both Mary swept the floor and Nancy mopped it. 5) 其它并列连词 常见的有：as well as, more than, rather than, no less than 等. (1) as well as 表示'同' 和'也' 的意义 as well as 用作并列连词时它意义相当于not only...but also, 但侧重点在后一并列成分上而as well as 侧重点却在前一并列成分上,A as well as B=not only B but also A. (2) more than 表示而不是之意. 例如: (3) rather than 表示'而不是' 之意. (4) no less than 表示' 同... 一样' 之意. 当as well as ,more than, rather than, no less than 连接两个成分作主语时谓语动词应于第一个成分的数相一致. 在使用并列连词时我们应该注意:
when 的用法 一、when 用作副词。 1. 用作疑问副词，引导特殊疑问句。(什么时候，何时 [at what time ])例如： ①When will you come to see me? ②When are they going to visit the Great Wall? 2. 用作连接副词，通常用来引导名词性从句[主语从句、表语从句、同位语从句、宾语从句]及起名词作用的“when ＋动词不定式”结构。(什么时候，何时 [at which; on which ])例如： ①When he comes is not known. [主语从句] ②The morning is when I am busiest. [表语从句] ④I don't know when the plane takes off. [宾语从句] ⑤I don't know when to leave for London. [宾语] 3. 用作关系副词，引导限定性定语从句和非限定性定语从句。(在…的时候 [at/on/in/during which])例如： ①Do you still remember the days when we stayed in America? ②The day will come soon when the Chinese astronauts will go to the moon. ③It happened ten years ago, when I was a child. ④We will go to the countryside at the beginning of June, when the summer harvest will start. 二 . when 用作连词。 1. 用作从属连词，意为“当……的时候[at the time when ]”，引导时间状语从句。例如： ①They learned a lot from the peasants when they stayed in the village. ②It was snowing when he arrived at the station. 【点津】如果 when 引导的从句中的主语和主句中的主语一致，且从句中的谓语动词是“be ＋分词”或从句主语是 it ，则 be 动词及其主语常可省略。例如： ③When（ he was ）asked why he was late, he made no answer. ④I'll tell him about it when（ it is ）possible. 2. 用作从属连词，意为“一……就……”，引导时间状语从句。[immediately after]例如： ①We will stand up when the teacher comes into the classroom. 老师一进教室我们就起立。 ②Fire the rockets when I give the signal. 3. 用作从属连词，意为“还没 / 刚刚/刚一……就”，引导时间状语从句。[immediately after]例如： ①I had hardly opened the door when he came in. 我刚一开门，他就进来了。 ②I had not been reading for half an hour when I heard someone call my name. 【点津】hardly…when和no sooner…than的结构要注意三点：意思为“一A就B“；A句通常用完成时态；hardly 和 no sooner 位于句首时要注意部分倒装。 4. 用作从属连词，意为“倘若，如果”，表示条件。例如： ①Turn off the switch when anything goes wrong with the machine. 如果机器发生故障，就把电源关上。 ②He will be likely to recover when he is operated on. 5. 用作从属连词，意为“既然，尽管”，表示让步。例如： ①Why use metal when you can use plastic?既然能用塑料,为什么用金属? ②They kept trying when they knew it was hopeless. 尽管他们知道那件事没有希望，可是他们还在不断地努力。6. 用作并列连词，意为“在那时，届时;就在这时”，表示时间。这时主句中可以用过去进行时，过去完成时或“ was/were about to do sth. ”结构。 ①Last night I was about to go to bed when the phone rang. ②I was cooking in the kitchen when someone knocked at the door. ③He had just finished the book when supper was served. 7. 用作并列连词，意为“虽然、然而、可是”，表示转折。例如： ①He usually walks to work when he might take a bus. 虽然他可 以坐公共汽车上班，但他却常常步行上班。 ②I had only twenty dollars when I needed thirty to buy the dictionary.我需要 30 美元买那本字典，可是我只有20美元。 8. 用作并列连词，意为“而、却”，表示对比。例如： How can he say that everything is fine when it's obvious that it is not? 他怎能说一切都好呢？情况显然不是那样。 三 . when 用作代词[which time]。 when 作为代词常常位于介词之后，意为“那时，什么时候”。例如： ①Since when have you been studying Japanese? 【点津】since when 作引导词时是“介词（since）+关系代词（when）”的结构，when意为which time。since when常引导非限制性定语从句，从句应用完成时态。 ②I came here in 1949, since when I have been engaged in this work. 我1949年到这里，从那时起我就担任这项工作。 ③We came back on Tuesday, since when we have been working in the repair shop. ④We came a week ago, since when the weather has been bad. 四、when 还可用作名词，前面常常用定冠词 the。 the when 表示事 件发生的时间,常常与 the where, the how 并列使用。 He told the police the when and the how of the accident. 他告 诉警察事故发生的时间及发生的原委。 ［巩固练习］ 1.

并列连词?o r重要用法归纳 一、基本用法 1.或，或者，还是 Is the light red or green? 灯是红的还是绿的？ You can go today or tomorrow. 你可以今天或明天去。 We can go swimming, or we could stay here. 我们可以去游泳，也可以就呆在这儿。 2.用于否定句，表示“也不”： He never smokes or drinks. 他从不吸烟，也不喝酒。 He doesn’t like tea or coffee. 他不喜欢喝茶也不喜欢喝咖啡。 3.即，就是 20% of the population, or one in five 人口的百分之二十，即?5个中间有?1个 He studies zoology, or the science of animals. 他研究动物学，即关于动物的科学。 4.否则，要不然 Don’t drive so fast or you’ll have an accident. 不要开那么快，否则会出事的。 Hurry up, or you will be late. 赶快，否则你就迟到了。 二、用法说明 1. 表示“否则”“要不然”时，若隐含的是一个不真实的条件，则引出的句子要用虚拟语气： He studied hard, or he couldn’t have passed the exam. 他学习很努力，要不然他考试就不会及格了。 2. 当A or B用作主语时，谓语一般与靠近的主语保持一致： He or I am wrong. 不是他错了，就是我错了。 Were you or he there? 当时是你还是他在那儿??
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？”
并列连词when相关的句式归纳 2006年普通高等学校招生全国统一考试(辽宁卷)中有这样一道单项填空题:He was about halfway through his meal ___ a familiar voice came to his ears. A.why B.where C.when D.while 解析:答案是C。此处when作并列连词,表示“就在此刻(and just then)”“,突然(and suddenly)”,该句译为：“饭刚吃到一半儿的时候，熟悉的声音传到了他的耳朵里。” 这里when引导的并不是我们所认为的时间状语从句而是并列句。when的意思是这时而不是当什么时候。在这个句型中when所引导的从句恰恰是句意的重心，when在这里起到一个修辞的作用表示后一动作的发生的出乎意料，而前面一句是为后一句谓语动词的发生提供背景。when 为并列连词。在我们的教材中并不鲜见。如： I'd just about given myself up for lost when I was spotted by a ship. 我正感到绝望时，一艘船发现了我。【Unit 3 Book 3】 33. She had just finished her homework ___ her mother asked her to plactised playing the piano yesterday.【09福建卷】 A. when B. while C. after D. since 7. Tom was about to close the window ___ the attention was caught by a bird. 【10全国卷】 A. when B. if C. and D. till 1．be (just) about to do... when... She was just about to say something more when she noticed the sullen look on his face．她刚要再说些什么，却突然看到了他阴沉的脸色。 We were about to telephone you when your telegram arrived. 2．be (just) on the point of doing sth ... when... They were on the point of giving up when the captain encouraged them fiercely to save the ship． 就在他们快要放弃努力时, 船长鼓励他们竭尽全力挽救轮船。

连词用法—并列连词和连词短语 并列连词用来连接平行的词、词组或从句 but 1. 连接词或短语He drives not carefully but slowly. 2. 连接句子This isn't a good one but it will answer. 3. 用于句首But what else can we do? 4. 用于道歉的表达之后Sorry, but we’re behind schedule 5. 用于not…but…，表示"不是……而是……"Not you but I am to blame. 6. 用在某些否定语后，表示“只…"She knows no one but you 7. 用于next (last) but one 中，表示"隔壁再过去""倒数第…"He lives in the next house but one. 他住在隔壁再过去一家 8. can’t help but 不由得不…You can't help but respect them 9.although不能与连词but搭配使用 10.but 与 however的用法区别:两者均可表示转折或对比，意为“但是,可是,然而等， 但有区别: 1. 表示转折时，but 是连词 2. however 表示“然而",“可是”时，能位于句首，而且能位于句中(注意前后 使用逗号)，甚至句末(注意其前也用逗号)。如：Later, however, he changed his mind/He hasn't arrived. He may, however, come later/ He said that it was so; he was mistaken, however 注意：以上各例中的 however 不能换成 but，但可用 but 来改写。如： He said that it was so, but he was mistaken 3.当however连接两个句子时，其前通常应用分号，或另起新句即用句号，如： It's raining hard; however, I think we should go out. / It's raining hard. However, I think we should go out. 注意：上例中的 however 不能换成 but，但可用 but 来改写 (注意所用标点的变化)。如： It’s raining hard, but I think we should go out yet 1.yet用作连词时，与but一样也主要用于转折，意为"但是""而"： I have failed, yet I shall try again. 2.有时用在句首。如：Yet the house was cheerful 3.yet有时可与并列连词and或but连用，构成习语and yet和but yet，意为“虽然如 此""可是""然而"，与单独使用的yet意思相同。如：He’s not really nice-looking, and yet he has enormous charm 4.根据英语习惯，although不能与连词but搭配使用，但是although可以与yet搭配 连用（此时的yet可视为副词）.如：Although we are poor, yet we are happy while 1.表示时间的用法，为"当……的时候"We must strike while the iron is hot 2.表示让步的用法，其意为"尽管""虽然”如：While the work was difficult, it was interesting 3.表示对比的用法，其意为"而"但"，注意：这样用时，while引出的句子有时也可位 于句首。如：While most children learn to read easily, some need extra help./most children learn to read easily, whilesome need extra help
