初中英语复合句
初中英语复合句
英语中的复合句往往是学生学习的难点，因为句式复杂多变，而且主谓宾、定状补等句子成分运用到具体的句子中需要一定的语法知识作为基础，所以，一些学生以看到这些复杂的句式就会一个头变两个大。复合句(Complex Sentence)由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause)构成。下面我们就一起来看看复合句的有关语法知识。
主句是全句的主体，通常可以独立存在;从句则是一个句子成分，不能独立存在。
从句不能单独成句，但它也有主语部分和谓语部分，就像一个句子一样。所不同在于，从句须由一个关联词(connective)引导。
1、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，名词性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。
1)主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词
that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如：
What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是
如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下：
(1) It + be + 名词+ that从句
(2)It + be + 形容词+ that从句
(3)It + be + 动词的过去分词+ that从句
(4)It + 不及物动词+ that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用
的句型有：
It is necessary (important, natural, strange, etc.) that …
It is suggested (requested, proposed, desired, etc.) that…
2)宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。
1. 由连接词that引导的宾语从句
由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如：
He has told me that he will go to Shanghai tomorrow. 他已
经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“(should)+ 动词原形”。例如：I insist that she (should) do her work alone. 我坚持要她自
己工作。
The commander ordered that troops (should) set off at once.
司令员命令部队马上出发。
2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从
句相当于特殊疑问句，应注意句子语序要用陈述语序。例如：I want to know what he has told you. 我想知道他告诉了你
什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whoever needs help a warm support. 凡需要帮助的人，她都会给予热情的支持。
3. 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：a. 引导主语从句并在句首时;b. 引导表语从句时;c . 引导从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。例如：
Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
The question is whether she should have a low opinion of the test?现在的问题是她是否应该有一个低意见的测试? Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
初中英语语法大全——名词 一、名词概述 1.名词的定义 名词是表示人、事物、地点、现象及其他抽象概念等名称的词。英语中的名词有可数名词和不可数名词之分；有其所有格形式；在句子中通常做主语、宾语、宾语补足语、表语、定语等。 2.名词的分类 名词分为专有名词和普通名词两类。普通名词又分为个体名词、集体名词、物质名词和抽象名词。个体名词与集体名词多数是可数名词，而物质名词与抽象名词多数是不可数名词。
二、名词的数 名词按照其可数性可以分为可数名词和不可数名词。可数名词是指可以直接计算数目的名词。个体名词和集体名词多数是可数名词；不可数名词是指无法直接用数目计算的词。物质名词和抽象名词多数是不可数名词。 1.可数名词的数 在英语中，可以直接用数字进行计算的名词是可数名词，不能直接用数字进行计算的名词是不可数名词。通常个体名词和集体名词可以用数目来计算，视为可数名词;物质名词和抽象名词往往指泛指的物质或者抽象的概念，不能用具体的数字来表示，视为不可数名词。专有名词往往只指一个人或物，因此没有必要再用具体的数字来修饰，一般也视为不可数名词。
eg: I was having dinner at a restaurant. eg: The two children are playing table tennis in the school. eg: Mr.Black gave us some advice on how to learn English well. eg: Paris is the capital of France. ①规则复数变化形式 可数名词在表示两个或两个以上的概念时需要用复数形式。可数名词单数形式变成复数形式的一般规则如下表:

初中重点语法 从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。（参见以下各条） 3、各从句在句子中的位置以及用法： (1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。 例如：That is why he did not come to school yesterday. / It is because you are so clever. (2) 宾语从句：在句子中作及物动词或介词的宾语。 ①基本形式：（主句＋）连词+从句主语+从句谓语+... ②关于宾语从句连词的选择： 若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略; 若从句来源于一个一般疑问句,连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等) 例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将 代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster.(我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在 哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? ) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时； 如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待： be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。) (3) 状语从句：在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、 目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。 时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该 用现在时替代。如：When you finish the work, you may go out to play with Sam. (你完成工作就可 以出去和Jim一起玩了。) / I won’t leave until Mum comes back. (妈妈回来了我才会走。) 地点状语从句通常由where, wherever等引导。如：Go back where you came from! (哪里来还滚到哪里去！) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会 忘记去抓住那个偷我项链的贼,无论他会在哪里。) 原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如：He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。) 目的状语从句通常由so that..., so...hat..., in order that...等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如：He got up earlier so that he could catch the first train. (他起身 更早为的是赶上第一班车。) 结果状语从句通常由so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如：He lost so many bikes that he decided never to buy a new one. (他丢了那么多 辆自行车,他决定再也不买新车了。) 比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如：Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多) 让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如：Even if you pay the debt(债务) for me, I will not thank you because it has nothing to do with me. (即使你替 我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿 了一件T恤衫,尽管天很冷。)

定语从句 定语从句 （一）、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句。 定语定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语（动词不定式短语、动名词短语和分词短语）或句子，汉语中常用‘……的’表示。主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任。单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后。 如：1) The man who lives next to us is a policeman. 2) You must do everything that I do. 上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。 引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why 关系词常有三个作用：1、引导定语从句 2、代替先行词 3、在定语从句中担当一个成分 （二）、关系代词引导的定语从句 1.who指人，在从句中做主语 (1)The boys who are playing football are from Class One. (2)Yesterday I helped an old man who lost his way. 2. whom指人，在定语从句中充当宾语，常可省略。 (1) Mr. Liu is the person (whom) you talked about. 注意：关系代词whom在口语和非正式语体中常用who代替，可省略。 (3) The man who/whom you met just now is my friend. 3. which指物，在定语从句中做主语或者宾语，做宾语时可省略 (1) Football is a game which is liked by most boys. ( which 在句子中做主语) (2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语) 4. that指人时，相当于who或者whom；指物时，相当于which。 在宾语从句中做主语或者宾语，做宾语时可省略。 (5) The people that/who come to visit the city are all here. (在句子中做主语) (6) Where is the man that/whom I saw this morning? (在句子中做宾语) 5. whose通常指人，也可指物，在定语从句中做定语 (1) He has a friend whose father is a doctor. (2) I lived in a house whose roof has fallen in. whose指物时，常用以下结构来代替 (3)The classroom whose door is broken will soon be repaired. =The classroom the door of which is broken will soon be repaired. (5)Do you like the book whose color is yellow? =Do you like the book the color of which is yellow? 注：that 用法 (1)不用that的情况 (a) 在引导非限定性定语从句时。(错)The tree, that is four hundred years old, is very famous here. (b) 介词后不能用；在" such (the same) ... as ..." 句型中,关系代词要用as, 而不用which. We need such materials as (not which) can bear high temperature We depend on the land from which we get our food.

初中英语语法大全：名词 一名词的定义：表示人、事物或抽象概念的名称的词。 二名词的分类： 名词可以分为专有名词（Proper Nouns）和普通名词 (Common Nouns），专有名词是某个（些）人，地方，机构等专有的名称，如Beijing，China等。普通名词是一类人或东西或是一个抽象概念的名词，如：book，sadness等。普通名词又可分为下面四类： 1）个体名词（Individual Nouns）：表示某类人或东西中的个体，如：gun。 2）集体名词（Collective Nouns）：表示若干个个体组成的集合体，如：family。 3）物质名词（Material Nouns）：表示无法分为个体的实物，如：air。 4）抽象名词（Abstract Nouns）：表示动作、状态、品质、感情等抽象概念，如： work。 … 注意专有名词一般第一个字母要大写。专有名词前一般不加冠词。 名词的种类 注意物质名词与抽象名词一般无法用数目来计算，称为不可数名词。不可数名词前不能加冠词a或an来表示量。 （三）名词的数 1.可数名词有单数和复数两种形式： 1.单数 英语中，如果我们要表示一本书、一只鸟、一棵树等概念时，要用名词的单数形式，表示名词的单数，要在名词前加冠词a或an。 This is a desk . 这是一张书桌。
[ There is an orange on the table . 桌上有一个橘子。 an orange 一个橘子an new orange （×）→a new orange （○） 一个新橘子 a desk a old desk （×）→an old desk （○）一张旧课桌 a和an的使用区别 a加在以辅音开头的名词前，如a book，a pen。 an加在以元音开头的名词前，如an egg，an apple。 注意 ！ 有时a，an后面紧接的不是单数名词，而是a (an) +形容词+单数名词的形式。 这时判断用a还是an来表示“一个”的概念时，要看形容词开头字母的发音，而不 是看名词。 2.复数 英语中，如果要表示两本书、三个学生、四把椅子这些两个或两个以上的概念时，要用名词的复数形式，名词的复数形式是在单数名词后加上词尾-s或-es构成的。 变复数时情况如下： （1）一般情况下,在词尾加s. eg.book——books,dog——dogs,pen——pens,boy——boys 以轻辅音结尾的名词后的s的读音为[s]，以浊辅音和元音结尾名词后的s读音为〔z〕。 （2）以s,x,ch,sh结尾的词名词变复数时,要在词尾加es.
