连词知识讲解

概念：连词是用来连接词与词、词组与词组或句子与句子、表示某种逻辑关系的虚词。连词可以表并列、承接、转折、因果、选择、假设、比较、让步等关系。分类：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4类：并列连词.转折连词.选择连词和因果连词。连词也可以分为2类：并列连词和从属连词

常见的表示语义引申的并列连词有：1. and

Justice is on your side. And justice will triumph over injustice. 正义在你们一边，而正义是会战胜非正义的。2. neither... nor

She could neither speak the language nor write it. 这种语言她既不会说，也不会写。

3. both... and

A man should have both courage and perseverance.一个人既要有勇气又要有毅力。

4. not only... but also

We should not only be bold, but also be cautious. 我们不仅要大胆，而且要谨慎。

5. as well as

I have read one of his novels as well as a few of his plays. 我读过他的一本小说和几个剧本。表示选择的并列连词有：1. or

You may do it yourself, or ask someone else to do it. 你可以自己做或者让别人做。

2. either... or

I left it either on the table or in the drawer. 我不是把它放在桌子上了，就是放在抽屉里了。除了表示选择外，or和either... or还可以表示否定的条件：1) Now I must go or (if not) I shall be late for the party. 我现在得走了，否则晚会我就要迟到了。2) You'll either behave yourself, or you'll never go out with me. 你要么老实点，要么就永远不能跟我一起出去。表示转折或对比的并列连词有：1. but He tried hard but he was unsuccessful. 他做了很大努力但没有成功。2. yet

The car was old, yet it was in excellent condition. 这辆车子很旧，但仍处于良好的状态。3. however

She felt ill. She went to work, however, and tried to concentrate. 她病了。然而她照旧去上班，并且尽力集中精神工作。4. nevertheless

连词ant but so because用法

并列连词and，but，so，because用法基本用法 1.and的用法 and用来连接两个并列的成分，表示添加、补充、引申。 She sings and dances very well. 她唱歌跳舞都很好。 My tall friend is handsome, intelligent and strong. 我的那个高个子朋友长得英俊，头脑聪明，身体又强壮。 2.but的用法并列连词but意为“但是”，表示转折关系，所连接的成分意思相反或相对。例如：（1）Our school is small but beautiful.我们学校虽然小但很漂亮。（连接两个形容词，意思相对）（2）The car is very old but it runs very fast.虽然小汽车旧了，但跑得很快。 3.so的用法并列连词so表示“因此、所以”之意，常用来连接两个简单句，这两个简单句有意思上的因果关系。例如：（1）The rain began to fall,so we went home.天开始下雨了，所以我们就回家了。（2）Everyone in the town knew him ,so we had no trouble finding his house.镇上谁都认识他，因此他们毫不费力就找到了他的家。 so和从属连词because（因为）不能一起连用。也就是说，使用了并列连词）。

就不用because(从属连词）；使用了because，就不用so。例如： He was ill,so he didn't go to school 他病了，所以没去上学。 He didn't go to school because he was ill.他没去上学,因为他病了。 1.表示原因，语气较强，可用来回答why 提出的问题。如： A：Why do you love her? 你为什么爱她? B：Because she is kind. 因为她很善良。 2.汉语说“因为……所以……”，但英语却不能用because…so…这样的结构。because不能和so连用，一山不能容二虎如：正：Because he is ill，he can't come．因为他生病了，所以来不了。正：He is ill，so he can't come．他生病了，所以来不了。误：Because he is ill，so he can't come．相关练习题一、用and, but, so，because填空填空。 She is tall ________ thin. He is not my father, ________ my uncle. I didn’t get up at 7:00 this morning, ________ I was late for school. I study hard , ________ I want to pass the exam. I am tired today, ________ I go to bed early. He is not my friend, ________ my enemy. The story is very interesting , ________ we all like it . The door was locked, ________ we couldn’t get in . It is very cold , ________ wear a heavy coat.

because, since, as与for用法辨析

because, since, as与for用法辨析 1. because的用法 because语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行。如： A：Why didn’t she come? 她为什么没来? B：Because she was very busy. 因为她很忙。 It is because he is clever that I like him. 是因为他聪明我才喜欢他。 2. since与as 两者所表示的原因都是人们已知的，即对已知事实提供理由，而不是表示直接原因。since 比 as 语气稍强，且比 as 略为正式，它们引导的从句通常放在主句之前，有时也放在主句之后。如： As you weren’t there, I left a message. 由于你不在那儿，我留了个口信。 Since you’ve been here a w hile, you might as well stay. 既然你已经来了一段时间，就不妨继续待下去。另外，since 可用于省略句，而其他三者不行。如： Since so, I have nothing to say. 既然如此，我无话可说。 3. for的用法

for是并列连词，而其余三者为从属连词。for有时可表示因果关系(通常要放在主句之后，且可与 because 换用)；有时不表示因果关系，而是对前面分句内容的解释或推断(也要放在主句之后，但不能与because 换用)。比较： The ground is wet，for (＝because) it rained last night. 地面是湿的，因为昨晚下过雨。 It must have rained last night，for the ground is wet this morning. 昨晚一定下过雨，你看今天早上地面是湿的。 (此句不能用 because 代 for) 英语微信群是目前学习英语最有效的方法，群里都是说英语，没有半个中文，而且规则非常严格，是一个超级不错的英语学习环境，群里有好多英语超好的超牛逼的人，还有鬼佬和外国美眉。其实坦白说，如果自己一个人学习英语太孤独，太寂寞，没有办法坚持，好几次都会半途而废。只要你加入到那个群里以后，自己就会每天都能在群里坚持学，坚持不停地说和练，由于是付费群，群里的成员学习氛围非常强，每天的训练度都非常猛，本来很懒惰的你一下子就被感染了，不由自主地被带动起来参与操练，不好意思偷懒，别人的刻苦学习精神会不知不觉影响你，EYC英语微信群（群主vx 601332975）可以彻底治好你的拖延症，里面学员都非常友好，总是给你不断的帮助和鼓励，让你学英语的路上重新燃起了斗志，因为每天都在运用，你的英语口语就能得到了迅猛的提升，现在可以随便给一个话题，都能用英文滔滔不绝的发表5分钟以上对这个话题的看法和观点，想提高英语口语的可以加入进来，It really works very well.

because of 的用法

1. because of 是复合介词，其后可接名词或代词，动名词以及由关系代词型的所what 引导的从句等(但不能接that从句)。如： He lost his job because of his age. 由于年龄关系他失去工作。 I said nothing about it, because of his wife’s being there. 因为他妻子在那儿，我对此事一字未提。 He knew she was crying because of what he had said. 他知道她哭是因为他所说的话。注：请注意下列正误句子：正：He cannot go to school because of sickness. / He cannot go to school because he is sick. 他因病不能上学。误：He cannot go to school because of (that) he is sick. 2. 由because of 构成的介词短语一般只用作状语，而不用作表语。作表语时可用due to。如：误：Tom’s absence was because of the rain. 正：Tom’s absence was due to the rain. 汤姆因下雨不能到场。注：在阅读中有时也可见到because of 短语用作表语，但值得注意的是，此时句子的主语通常中代词而不是名词。如： It is because of hard work. 那是因为劳累的原因。 That will be because of money. 那将是因为金钱的缘故。

连词的用法教案(一)(初中英语)

教学过程一、复习预习教师引导学生复习上节课所学的内容复习，（以提问、回顾的形式进行），针对上节课的作业进行讲评、订正、答疑，并通过简单的句子导入本节课所要学习的连词。连词含义：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。二、知识讲解知识点1：并列关系连词的用法在句子中并列连词用来连接平行的词、词组和分句。常用的并列连词有：and，both…and,not only…but also,as well as，neither…nor等。 1. 【考查点】单个连词及固定搭配的用法。如：They sat down and talked about something. 他们坐下来并且讨论一些事情。 She plays not only the piano, but (also) the guitar. 她不仅弹钢琴而且还弹吉他。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. 他不仅喜欢读故事书，甚至能写一些。 2.【易错点】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. 在月球上没有空气和水。 There is no air and no water on the moon. 在月球上没有空气没有水。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。知识点2：表示选择关系的连词 1.【考查点】选择关系的连词及固定搭配 or意思为"或则"。either…or意思为"或者……或者……"or else/ otherwise 否则如：Which do you prefer, tea, coffee, or juice ? 你喜欢哪一个，茶，咖啡还是果汁？ Either you or I am right. 你和我有一个是正确的。 Be silent, or else you will be kicked out. 保持沉默，否则你将会背开除。 I am tired, otherwise, I would play. 我很累，不然的话我就去玩了。知识点3：表示转折或对比关系的连词 1.表示转折关系和对比关系的连词有but，while，yet，however等 2.【考查点】转折关系连词的用法如：He is rich but unhappy. 他很富裕但不快乐。 Some people love cats, while others hate them. 有些人喜欢猫，而有些则讨厌他们。 She said she would be late, yet she arrived on time. 她说她将会迟到，然而他却准时到达了。 She does not like him, however, I like him. 她不喜欢他，但是我喜欢他。 They were not the bones of an animal, but (the bones) of a human being. 他们不是动物的骨头而是人类的。注意：not 和but 后面的用词要遵循一致原则。 2.【易错点】but和however的区别。However后有逗号，but没有。知识点4：表示因果关系的连词 1.【考查点】for因为，做并列连词使用时，是在对先行的句子补述原因或者理由，以连接句子与句子，通常不置于句首。so, therefore 因此，then那么，因而。如：He is absent today, for he is ill. 他今天缺席了因为他生病了。 He hurt his leg, so he couldn't play in the game. 他的腿受伤了，因此不能参加这个游戏。知识点5：谓语动词单复数的判断 1.【考查点】句子有as well as,neither…or等连词时注意谓语动词的单复数。

初中英语连词讲解

初中英语连词讲解一、概念连接词与词、短语与短语、句子与句子的词叫连词。例如： It is neither too cold nor too hot in spring. (neither…nor连接两个词) You can read either in the morning or in the afternoon. (either…or连接两个短语) Hu Lan was late yesterday because she woke up too late. (because连接两个句子) 二、连词的种类从连词本身的含义及其所连接的成分的性质来看，可分为两类：并列连词和从属连词。（一）并列连词，用来连接有并列关系的词、短语或分句的连词是并列连词；并列连词连接分句构成并列句。 1、常用来连接同类性质的词与词、短语与短语的并列连词有and, or ,neither…nor,either…or, not only…but also, both…and. ⑴ and 和，并且 My uncle lives and works in Shanghai. He’s big and tall. ⑵ or 或（费否定句中），和（否定句中） Are you a teacher or a student? You can take some food or some money. I don’t like reading or writing. ⑶neither…nor既不…也不…，要么…要么… either…or 或者…或者… not only…but also不仅…而且… both…and既…又… You can come to see me either on Sunday or on Saturday. I don’t like its color, it is either too dark or too light. The boy is both tall and fat. My daughter can not only sing but also dance. 注意：both…and连接并列主语时，谓语动词用复数；neither…nor,either…or, not only…but also连接并列主语时谓语动词和邻近主语保持一致。 2、常用来连接并列分句构成并列句的连词有and, or, but,so ⑴or否则，相当于一个否定条件句。 Hurry up, or you’ll be late. (If you don’t hurry up, you’ll be late.) ⑵ and 这样的话，就会…，相当于一个肯定条件句。 Study hard, and you can get good grades. (If you study hard, you can get good grades.) ⑶ however 然而， but 但是，可是，而,前后分句是转折关系。 Mr. Mott is very poor, but he feels happy. ⑷ so 于是，因此，并列具有因果关系的两个分句。 We wanted to learn the English songs, so we asked the teacher to teach us. (二)从属连词：引导从句的连词叫做从属连词，分为连接代词和连接副词两种。 1、引导宾语从句的有that, when, where, who, why, what, if, whether ⑴ that 用于引导由陈述句转换过来的宾语从句，可以省去。如： She says that she likes watching TV very much. ⑵ when,where,who, why, what等连接由特殊疑问句转换过来的宾语从句。如： Do you know when the train arrives? Can you tell me where you come from? ⑶ if, whether连接由一般疑问句转换过来的宾语从句。如：

since, for, because, as, now that 表原因的用法区别

since, for, because, as, now that 表原因的用法区别 in that通常用now that，是既然的意思。 since，for，because,now that的用法和区别: 1.since（既然）语气较弱，强调已知的事实。例：Since you can't answer the question, I'll ask someone else. 既然你回答不出这个问题，我就问别人了。 2. for（因为）的用法： for是并列连词，表示推断的原因，或对前一分句补充说明理由。例：It must be morning for the birds are singing.一定是清晨了，因为鸟儿在叫。 3. because （因为）的用法： because通常表示直接的原因。because引导的从句表示直接而明确的原因和理由，表示按因果关系的推断，语气很强，用来回答why的问题, 一般位于主句之后。例：We couldn't go out because it was too cold. 因为天气太冷，我们不能外出。 4. now that（既然）的用法： now that同since相似，语气较弱，强调人们已知的事实。例： Now that you are busy, let me do it for you. 既然你忙，就让我给你做吧。 5. as意为“因为、由于”，语气比because弱，所引导的从句表示的是不言而喻、显而易见的原因和理由，其从句一般放在主句前，如：As it was late ，we came back soon.（由于时间很晚了，我们很快就回来。）区别：since和now that，表示事物发展的自然结果，特别是当对方大概已经了解其原因的情况下使用，表示既成事实的原因一般位于主句之前。注意：for是并列连词，引出的原因较间接，似乎是事后所想到的补充解释的理由，只陈述一般推断的理由，不一定表示产生结果的必然原因，主要放在两个并列句之间。because通常表示直接的原因。 As to 与As for 用法小结在英语中表示“就……而论”“有关”或“至于”含义的词语颇多，其中as to 和as for 亦表此义，但二者用法不尽相同。 as to 的功能类似于with regard to，regarding，on the matter of，concerning 等，常用于相当正式的语境中，尤其用于争论和做出决定时。可放于句首或与wh- 疑问词引导的动词不定式和名词性从句连用（有时可省略），而as for 无此种用法。例如： As to the journey，we must decide about that later. 至于旅行，我们必须以后再作决定。 As to the flood，I have heard nothing. 至于那次水灾，我没听到什么。 Nobody could decide （as to ）what to do. 谁也不能决定该做些什么。 He is very uncertain as to whether it's the right job for him. 关于他究竟是否适合做这项工作，他实在拿不准。 A question arose as to who should be the monitor. 关于谁当班长的问题出现了矛盾。 I want to find out as to whom this bicycle belongs to. 我要打听出来这辆自行车是谁的。 as to 有时用于表示according to 的含义。例如：
