高中英语语法复习连词
【英语语法】
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。
(一)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.
(二)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：
引导时间状语从句的：after, before, when, as, while, since, until, till, as soon as
引导原因状语从句的：because, since, as
引导让步状语从句的：although, though, no matter(无论), even if (though)引导条件状语从句的：if, unless, once, so (as) long as
引导结果状语从句的：so …that …, such …that …
引导目的状语从句的：so that …, in order that …
引导比较状语从句的：as …as …, not so (as) …as …, …than …
引导方式状语从句的：as if …
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。
(三)某些用法比较特殊的从属连词用法区别
1、当while, when, as引导时间状语从句时的区别：①while引导的状语从句中动词必须是持续性。谓语动词多为进行时，或状态动词的一般时。while 的这些用法可用when代替，等于at the time that , during the time that 。例如：Please keep quiet while (when) others are studying;②when除可指一段时间外，还可用来指一点时间，等于at the time ，也就是说when引出的时间状语从句中的谓语动词可以是终止性的，也可以延续性的。因此主句和从句的谓语可以是一般时，进行时，或完成时。例如：When I went into the lab, the teacher was doing an experiment.(when不能换成while)He often makes mistakes when he is speaking English.(when可换成while)③as常可与when，while通用，但强调一边、一边。例如：As (when, while) I was walking down the street, I noticed a police car in front of number 37. ④when引导的状语从句中的主语与主句主语一致，主、谓是主语+系动词结构时，这时主语和系动词可以省略。例如：When (he was) young, he worked for a rich man./ She ll be here to give you help when (if it is) necessary. ⑤when有时代替if，引导条件句，意为如果、假如，例如：I ll come when (if) I m free.
2、before作连词一般表示时间，意为在…之前，但有些句子中这样译就显得别扭。试看以下句子的翻译：He almost knocked me down before he saw me.他几乎把我撞倒才看见我;Before I could get in a word he had measured me.我还没来得及插话，他已经给我量好了尺寸。
3、till, until作为介词式从属连词引导时间状语短语或状语从句，用于否定句时，结构为not …until (till)，主句谓语动词延续与非延续皆可，意为直到…才…。用于肯定句时，只与延续性动词连用，表示到…为止。例如：They played
（1）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类： (1) 从属连词that。如： The trouble is that I have lost his address. 麻烦是我把他的地址丢了。 (2) 从属连词whether, as, as if。如： He looked just as he had looked ten years before. 他看起来还与十年前一样。 The question is whether they will be able to help us. 问题是他们是否能帮我们。 注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago, but it's as if it was only yesterday. gh能跟表语从句的谓语动词一般为系动词be, seem, look等。如： It looked as if it was going to rain. 看起来天要下雨了。 连接副词 where, when, how, why。 如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 The question is how he did it. 问题是他是如何做此事的。 That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 解释： 1．连词because可引导表语从句。如： I think it is because you are doing too much. 我想这是因为你做得太多。 2．在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。（2）主语从句 1．定义：用作主语的从句叫做主语从句。 2．构成：关联词+简单句 3．引导主语从句的关联词有三类： (1) 从属连词that。如：That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们确是亲姐妹，她们的脸型很相似。 (2) 从属连词whether。如： Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。 (3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接副词 where, when, how, why。如： What she did is not yet known. 她干了什么尚不清楚。 How this happened is not clear to anyone. 这事怎样发生的，谁也不清楚。 Whoever comes is welcome. 不论谁来都欢迎。 Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。 解释： 1．主语从句能用it作形式上的主语。常以it作形式主语的句型有： A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如： It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。 It is probable that he told her everything. 很可能他把一切都告诉她了。 B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that

It 作形式主语与ｉt引导强调句得比较 It 作形式主语代替主语从句,主要就是为了平衡句子结构,主语从句得连接词没有变化、而i ｔ引导得强调句则就是对句子某一部分进行强调,无论强调得就是什么成分,都可用连词that。被强调部分指人时也可用who/ｗｈｏｍ、例如: ａ) It isａpitｙｔhaｔyoｕｄidn’t go ｔo seｅｔhｅｆilm.您不去瞧那场电影真可惜。 b) It doeｓn’tｉntereｓt me whethｅrｙou sｕｃceed or not、我对您成功与否不感兴趣、 c) Ｉｔisｉn thｅｍoｒnｉng thaｔｔｈe ｍurder took place. 谋杀案就是在早上发生得、(强调句型) d) Ｉt is Joｈn tｈat broke ｔｈeｗｉｎdow。就是Joｈn打碎得窗户。(强调句型) 2、用ｉt 作形式主语得结构 (1)It is + 名词＋从句 It is ａfaｃt tｈat…事实就是… Ｉt ｉs an honor ｔhat …非常荣幸 It ｉｓｃommon knowlｅdge ｔhat …就是常识 (2)Ｉt is + 形容词+从句 It is naturａl thａt…很自然… It ｉｓstrａｎｇe that…奇怪得就是…(3) It ｉｓ＋不及物动词+ 从句 Ｉｔｓｅems thａｔ…似乎… Ｉt ｈappeneｄthat…碰巧… Iｔappeaｒs that…似乎…

七选五练习 （一） When I was in high school and college, I went to fast food restaurants pretty often. Even until today, fast food is a popular choice among students. So, what makes fast food restaurants really popular year after year? The food is not very expensive. 1 So, it is good to get something tasty to eat and still have some money left for a movie later. Nowadays, many fast food restaurants open till late nights. 2 Most teenagers go there also because other boys and girls are there. It is fun to be there, as seen in fast food TV advertisements. It is cool. 3 You can just order fries or you can also mix and match with plenty of choices, such as coke with French fries, sundae with apple pies, salad with burgers. And managers there will not stare at you for reading there for hours if you just order French fries and a cup of coke. 4 They can have group discussions of school projects, small talk and even birthday celebrations. You can try telling them some fast food is unhealthy, but I doubt if youngsters will listen. 5 Some of them go to a fast restaurant every week. The food there is cheap, delicious, and served fast. A. Fast food does not have to be bad for you. B. Many teenagers do not have much money. C. Fast food is still popular with many of them. D. At fast food restaurants, you choose what you want. E. Today, fast food restaurants are offering healthier food. F. A fast food restaurant is a good place for some activities for teenagers. G. So, these places are comfortable and safe to hang out during late nights.

He said, “ I like it very much.”→He said that he liked it very much. 2. He said to me, “I’v left my book in your room.” →He told me that he had left his book in my room. 时态的变化
高中英语语法总结 第一章主谓一致 (一) 语法一致原则: 即主语为单数,谓语用单数,主语为复数,谓语也用复数. 以下为注意事项: 1. 单数主语即使后面带有with , along with, together with, like(像), but (除了),except, besides, as well as, no less than, rather than(而不是), including, in addition to 引导的短语, 谓语动词仍用单数. 如: Air as well as water is matter. 空气和水都是物质. No one except two servants was late for the dinner. 除了两个仆人外, 没有一个人迟来用餐。 2. 用and连接的并列主语,如果主语是同一个人,同一事,同一概念, 谓语动词用单数, 否则用复数. 如: The poet and writer has come. 那位诗人兼作家来了.(一个人) A hammer and a saw are useful tools. 锤子和锯都是有用的工具. (两样物) 用and连接的成对名词习惯上被看成是一个整体, 如:bread and butter(黄油抹面包), knife and fork(刀叉)等作主语时, 谓语动词用单数。 3. 不定式(短语), 动名词(短语), 或从句作主语时, 谓语动词用单数. 如: Serving the people is my great happiness. 为人民服务是我最大的幸福. When we’ll go o ut for an outing has been decided. 我们什么时候出去郊游已决定了。 4. 用连接的并列主语被each, every 或no修饰时, 谓语动词用单数. Every boy and every girl likes to go swimming. 每个男孩和每个女孩都喜欢去游泳. No teacher and no student was absent from the meeting. 没有老师也没有学生开会缺席. Each man and (each) woman is asked to help. 每个男人和每个女人都被请去帮忙。 5. each of + 复数代词, 谓语动词用单数. 复数代词+each, 谓语动词用单数.如:Each of us has something to say. 我们每个人都有话要说。 6. 若主语中有more than one 或many a/an , 尽管从意义上看是复数, 但它的谓语动词仍用单数。但more+复数名词+than one做主语时, 谓语动词仍用复数. 如: Many a boy likes playing basketball. 许多男生都喜欢打篮球. More than one student was late. 不只一个学生迟到 More persons than one come to help us. 不止一个人来帮助我们。 7. none 做主语时,谓语动词可用单数, 也可用复数; 但在代表不可数的东西时总是看作单数,因而谓语动词要用单数. 如: None of us are (is) perfect. 人无完人。 None of this worries me. 这事一点不使我着急。 8. 名词如: trousers, scissors, clothes, goods, glasses 等作主语时, 谓语动词必须用复数. 如: His clothes are good. 但这些名词前若出现a pair of , 谓语一般用单数.如: A pair of glasses is on the desk. 桌上有一副眼镜。 9. 形复意单名词如:news ; 以ics 结尾的学科名称如: physics, mathematics, economics; 国名如: the United States; 报纸名如: the New Times; 书名如: Arabian Night <天方夜谈>; 以及The United Nations<联合国> 等作主语时, 谓语动词用单数。 10. “a +名词+and a half “, “one and a half + 名词”, “the number of + 名词”等作主语时, 谓语动词要用单数. 如: Only one and a half apples is left on the table.
四种名词性从句(宾语从句、主语从句、同位语从句、表语从句)讲解与练习 ◆学习宾语从句 学习宾语从句的连词、语序、时态和各种变化及特殊用法(直接引证变间接引语也在 宾语从句的基础上还要进行人称、状语、少数动词和句型的变化)是为学习其它三种名词性从句(主从、表从、同位从)做铺垫，连词、语序、时态基本相同，只是后三种考点相对宾.语从句少的多，主要是对连词的应用进行考查。所以学好宾语从句是必要的。 宾语从句三注意三特殊 一注意:注意引导词(连词) 由陈述句转化而来的宾语从句，引导词为that，that 在口语或非正式文体中可省略;由 一般疑问句转化而来的宾语从句，引导词为if或whether;由特殊疑问句转化而来的宾语从句，引导词为句子本身的特殊疑问词，即what, when，where 等。 Eg：Tom says(that)he will fly to Beijing tomorrow. 汤姆说他明天将要坐飞机去北京 二注意:注意从句语序. 宾语从句的语序应该为陈述句语序即“主语+谓语+宾语+其他”。也就是说将疑问句转化成宾语从句时，一定要将疑问句语序转变成陈述句语序。 Can you tell me what he is doing能告诉我他正在做什么吗? <特别提醒>当疑问句在宾语从句中做主语时，语序不变。 Eg：Do you know what makes him so angry? 你知道什么事使他如此生气吗？ <特别提醒>如果宾语从句表示的是客观真理或是科学事实，其谓语动词仍用一般现在.时态。 Eg：Our teacher told us that the sun is much bigger than the moon. 老师告诉我们说太阳比月球大得多。 ◆主语从句(与宾词从句连词、语序、时态相同。只是不能用if, that 不可省;) (一)、主语从句是一个句子，在句子中作主语成分。 (二)，主语从句的特点 1.与宾语从句使用同样的连接词，只是if不能用; 1)、陈述句用that。 2)、一般疑问句用whether。 3)、特殊疑问句用特殊疑问词what, which, who,when, where, why, how等词引导。 2.以it为形式主语出现 Eg：1.It's true that the earth is round. That the earth is round is true. 2.表是否的意思时，不能用if代替whether. It hasn't been decided whether he'll come or not. Whether he'll come or not hasn't been decided. 3.从句语序为主谓宾正常语序。 Why didn't he come? Why he didn't come is not known. （三）特殊疑问词变化 Whoever=no matter who=any one who Whomever=no matter who=any one who

高中英语语法归纳总结 第一章名词性从句 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
b) It doesn’t interest me whether you sueed or not. 我对你成功与否不感兴趣。 c) It is in the morning that the murder took place. 谋杀案是在早上发生的。（强调句型） d) It is John that broke the window. 是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that ? 事实是? It is an honor that ?非常荣幸 It is mon knowledge that ?是常识 (2) It is ＋形容词＋从句 It is natural that?很自然?
16 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。 （一）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. （二）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： 引导时间状语从句的：after, before, when, as, while, since, until, till, as soon as 引导原因状语从句的：because, since, as 引导让步状语从句的：although, though, no matter（无论）, even if (though) 引导条件状语从句的：if, unless, once, so (as) long as 引导结果状语从句的：so … that …, such … that … 引导目的状语从句的：so that …, in order that … 引导比较状语从句的：as … as …, not so (as) … as …, … than … 引导方式状语从句的：as if … 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。 （三）某些用法比较特殊的从属连词用法区别 1、当while, when, as引导时间状语从句时的区别：①while引导的状语从句中动词必须是持续性。谓语动词多为进行时，或状态动词的一般时。while 的这些用法可用when代替，等于 "at the time that", "during the time that"。例如：Please keep quiet while (when) others are studying；② when除可指一段时间外，还可用来指一点时间，等于 "at the time"，也就是说when引出的时间状语从句中的谓语动词可以是终止性的，也可以延续性的。因此主句和从句的谓语可以是一般时，进行时，或完成时。例如：When I went into the lab, the teacher was doing an experiment.（when不能换成while）He often makes mistakes when he is speaking English.（when可换成while）③as常可与when，while通用，但强调"一边、一边"。例如：As (when, while) I was walking down the street, I noticed a police car in front of number 37. ④when引导的状语从句中的主语与主句主语一致，主、谓是"主语系动词"结构时，这时主语和系动词可以省略。例如：When (he was) young, he worked for a rich man./ She'll be here to give you help when (if it is) necessary. ⑤when有时代替if，引导条件句，意为"如果"、"假如"，例如：I'll come when (if) I'm free. 2、before作连词一般表示时间，意为"在…之前"，但有些句子中这样译就显得别扭。试看以下句子的翻译：He almost knocked me down before he saw me.他几乎把我撞倒才看见我；Before I could get in a word he had measured me.我还没来得及插话，
