初中英语语法归纳(精编)

1、初中英语语法归纳：名词初中英语学习最难的是语法，因为英语的语法跟汉语的语法有很大的不同。对于从小就生活在中国的同学们，学起英语语法来会显得特别吃力。下面为大家讲解一下初中英语名词的语法特点。一、名词(n.) 表示人、事物或抽象概念的名称的词(一)名词的分类名词分为普通名词和专有名词,其中普通名词包括可数名词和不可数名词，可数名词可用作单数，也可用作复数。可数名词包括个体名词(表示一类人或物的个体。如：boy,desk,cat,window)和集体名词(由若干个体组成的集合体。如：family,class,police)。不可数名词包括物质名词(表示无法分为个体的实物。如：water,paper

2、,silk,money)和抽象名词(表示性质、行为、状态、感情或其它抽象概念。如：work,happiness,music,difficulty,housework)专有名词表示个人、地方、机构、组织等。如：tom,the great wall,the spring festival,france,the united states)(二)名词的数1.可数名词有单数和复数两种形式，其复数形式的构成主要有以下几种：(1)一般情况下,在词尾加s.eg.bookbooks,dogdogs,penpens,boyboys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

3、s,x,ch,sh结尾的词名词变复数时,要在词尾加es.eg.beachbeaches,brushbrushes,busbuses,boxboxes(es读音为iz(3)以“辅音字母+y”结尾的名词,先变y为i,再加es.eg.citycities,familyfamilies,documentarydocumentaries,countrycountries,strawberrystrawberries(ies读音为iz)(注：以“元音字母+y”结尾的词，直接在词尾加-s.eg.boys,holidays,days)(4)以o结尾的名词，变复数时情况如下：,.tomatotomatoes,p

4、otatopotatoes, heroheroes negro negroes mongomongoesp结尾是两个元音字母的加s,eg.zoozoos,radioradios某些外来词变复数时词尾加s,eg. pianopianos一些名词的缩写形式变复数时，词尾加s,eg.photo(photograph)photos,kilo(kilogram)kiloszero变复数时，既可加s,也可加 eg.zeros/zeroes(5)以f或fe结尾的名词变复数时,先把f或fe变为v,再加es.eg.wifewives,leaf leaves,halfhalves,knifeknives,thie

5、fthieves(res读音为vz(注意：roof的复数为roofs; scarf的复数为scarfs/scarves)(6)有些名词由单数变复数时，不是在词尾加s或es,而是变换其中的字eg.manmen,womanwomen,policemanpolicemen,englishmanenglishmen,frenchmanfrenchmen, footfeet, toothteeth, childchildren,mousemice,oxoxen(公牛)(7)还有一些名词的单数和复数形式相同。eg.chinese,japanese,sheep,deer,fish(8)另一些名词本身即是复数

6、形式，不可用作单数。eg,people,police,trousers,pants,clothes,scissors另外,当一个名词作定语说明另一个名词时，这个名词一般用单数。eg.an apple tree,five apple trees,a girl friend,two girl friends,a twin sister但是，当man和woman作定语修饰复数名词时，就要用其复数形式。eg.two men teachers,three women doctors可用“量词+of+名词复数”这一结构表示可数名词的数量。eg.a room of students,two boxes of

7、 pencils2.不可数名词一般没有复数形式，它的“量”的表示方式如下。(1)表不定数量时,一般用much,(a)little,a lot of/lots of,some,any等词修饰。eg,much money,a little bread(2)表确定数量时,一般用“数词+量词+of+不可数名词。如：two/three/+量词复数十of+不可数名词。eg.a bag of rice,two glasses of milk,four bottles of water3.有些名词既可作可数名词也可作不可数名词，但词义有所不同。eg： fruit水果fruits表示不同种类的水果;food食物

8、foods各种食品;fish鱼fishes鱼的种类;drink饮料、酒a drink一杯/一份饮料、一杯酒; cloth布,a cloth桌布、抹布; sand沙sands沙滩; tea茶a tea一杯茶;chicken鸡肉a chicken小鸡;orange橘汁an orange橘子; glass玻璃a glass玻璃杯,glasses眼镜; paper纸a paper试卷、论文;wood木头a wood小森林;room空间、余地a room房间(三)名词的所有格(表示人或物的所属关系)(1)有生命的名词所有格以及表示时间、距离、城镇、国家等的名词所有格。不是以s结尾的名词变成所有格时，在词

9、尾加s.eg.mikes watch;womens day以s结尾的名词变成所有格时,只加。eg.teachersoffice,studentsrooms两个或两个以上名词并列,表示共同所有，只需在最后一个名词后加s.eg.tom and mikes room汤姆和迈克的房间(表示汤姆和迈克共有一间房)两个或两个以上名词并列，表示分别所有，需在几个名词后都加s.eg.marys and jennys bikes玛丽和詹妮的自行车(表示玛丽和詹妮各自的自行车)(2)无生命的事物的名词所有格常用of结构eg.a map of china,the beginning of this game,the

10、 door of the room(3)特殊形式可用s和of短语表示的名词所有格eg.the boys name=the name of the boy(男孩的名字)the dogs legs=the legs of the dog(狗的腿)chinas population=the population of china(中国的人口)chinas capital=the capital of china(中国的首都)双重所有格eg.a fiend of my mothers我妈妈的一个朋友a picture of toms汤姆的一张图片初中英语语法归纳：连词初中英语学习最难的是语法，因为英语

11、的语法跟汉语的语法有很大的不同。初中英语连词有很多种。下面为大家讲解一下初中英语连词的用法。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。第一类表示并列关系的连词并列连词：并列连词用来连接平行的词、词组和分句。1)and 和判断改错：(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 do

12、wn 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：1. and 还可以和祈使句或名词词组连用表示条件。(or

13、也有此用法)make up your mind, and youll get the chance.= if you make up your mind, youll get the chance.one more effort, and youll succeed.= if you make one more effort, youll succeed2, a and b 当表示整体或者指同一人时谓语动词用单数, 当and连接的单数名词前分别有each，every，many等词修饰时，谓语也用单数。bread and butter a knife and forkthe mother and

14、 teacher is very strict with her son.no teacher and no student is allowed to smoke in class.3. and连接的是两个相同意思的词，表示“渐渐”，或加强语气read it again and again2)both and两者都she plays (both) the piano and the guitar.3) neithernor 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.4)not onlybut (also)不但而且

15、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.5) as well as 以及，也，与同样the teacher, as well as the students, is interested in the activity.比较and和or1) 并列结构中，or通常用于否定句，and用于肯定句。2)

16、 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。第二类表示选择关系的连词1) or意思为或则。which do you prefer, tea, coffee, or juice ?2) eitheror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.3) or else/ otherwise 否则be

17、silent, or else you will be kicked out.i am tired, otherwise, i would play.第三类表示转折或对比关系的连词1) but 但是 he is rich but unhappy.while 然而，表示对比意味 some people love cats, while others hate them.yet 然而 she said she would be late, yet she arrived on time.however 然而，可是，不过 she does not like him, however, i like

18、him.2) notbut 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.第四类表因果关系的连词1) 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，只可以连接句子与句子，通常不置于句首。he is absent today, for he is ill.2) so, therefore 因此he hurt his leg, so he couldnt play in the game.i think, therefore

19、 i am3)then 那么，因而hide behind the wall, then they wont see you.注意：a. 两个并列连词不能连用，但therefore, then, yet.可以和并列连词连用。you can watch tv, and or you can go to bed.he hurt his leg, and so / and therefore he couldnt play in the game.b. although yet，但although不与 but连用。(错)although he was weak, but he tried his be

20、st to do the work.(对)although he was weak, yet he tried his best to do the work.从属连词从属连词不同与并列连词，只能用来引导从句，而不能引导词或者词组。从属连词一般可以引导名词性从句和状语从句。第一类引导名词性从句的从属连词1) that 引导宾语从句或间接引语时，可省略。引导主语从句时不可以省略。he said (that) he would come. 宾语从句his mother told me (that) he is a good boy. 间接引语that she is still alive is t

21、rue. 主语从句2) if/whether 是否i wonder if he is at home.i ask him whether he would come.注意：只可以用whether的情况介词后面 it will depend on whether it rains tomorrow.whetheror not 固定搭配 let me know whether you come or not.动词不定式前 i dont know whether to accept his advice.第二类引导状语从句的从属连词1) 连接时间状语从句的从属连词before 在之前 the war

22、 had been over before he came to china.after 在之后 he came to china after the war was over.since 自从 i have lived in this city since i was born.when/while 当 the teacher entered the classroom, when all the students were playingwhen i came into this room, i found him lying bed asleep (while后接的动词是延续性的动词)a

23、s 当 i saw her as i was getting on the bus.till/until 直到 i didnt go to sleep until/till i finished my homework.as soon as 一就 as soon as he saw the policeman, the thief run away.2) 连接地点状语从句的从属连词where 在哪里 there were lots of parks where i lived.3) 连接原因状语从句的从属连词because 原因,用于解释某事的原因，动机，强调直接原因和因果关系 i do it

24、 because i like it.for 表因为，表间接的原因，用于说明，解释 i soon went to sleep, for i was tiredsince 表原因，比because弱，比as强，表一种已知的，显然的理由，常译为“既然as 表原因时，意义最弱 as you are in poor health, you should do more exercises4) 连接结果状语从句的从属连词sothat 如此以至于 he is so kind that everybody likes him.suchthat he is such a kind man that every

25、body likes him5) 连接目的状语从句的从属连词that / so that / in order that 为了speak clearly that/so that/ in order that they may understand you.6) 连接条件状语从句的从属连词if 如果 if it rains tomorrow, we wont go on a picnic.unless 除非 (如果不 ) he will come unless it rains.in case 万一 you may call this number in case i am not at ho

26、me7)连接比较状语从句的从属连词than 比 its easier than i thought.as/soas和一样 she is as tall as you.he is not as/so tall as his wife.8)连接方式状语从句的从属连词as 按照 do as i told you.take things as they are.as if / though 仿佛 he behaves as if/though he was a child.9)引导让步状语从句的从属连词although/though 尽管 although japan is small, the po

27、pulation is big.even if 即便 even if it was snowing heavily, we went on running.初中英语语法归纳：副词初中英语学习最难的是语法，因为英语的语法跟汉语的语法有很大的不同。初中也要副词用法有很多种。下面为大家讲解一下初中英语副词的用法。副词在句中主要用作状语，修饰动词、形容词、副词、介词短语或句子。初中英语副词的用法： 修饰动词，表示时间、地点、程度、方式、频度等。一般位于动词之后，如果动词有宾语，则要位于宾语之后。频度副词常位于助动词和连系动词be 之后或实义动词之前。例如：he arrived only yesterd

43、r seen such a strange guy(家伙).(我从未见过这样奇怪的家伙) / it is quite a nice day for a walk.(这真是散步的好日子)初中英语语法归纳：数词初中英语的语法跟汉语的语法有很大的不同，初中英语数词是其中之一。表示数目和顺序的词叫数词，数词可分为基数词和序数词两类。下面为大家讲解一下初中英语连词的用法。(一)基数词基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基数词如下表所示。1 one 11 eleven 100 a hundred2 two 12 twelve 20 twenty 1000 a thousand3 thr

44、ee 13 thirteen 30 thirty 1，000，000 a million4 four 14 fourteen 40 forty 10，000，000 ten million5 five 15 fifteen 50 fifty 100，000，000 a hundred million6 six 16 sixteen 60 sixty 1，000，000，000 a billion7 seven 17 seventeen 70 seventy8 eight 18 eighteen 80 eighty9 nine 19 nineteen 90 ninety10 ten说明：1.13

45、19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。2.2090由个位数加后缀-ty构成，注意其中2050的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。3.其它非整十的两位数2199是由整十位数加连字符“-”，再加个位数构成。如： 81 eighty-one。4.101999的基数词先写百位数，后加and再写十位数和个位数。如： 691 six hundred and ninety-one。5.1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。如：5893 five tho

46、usand eight hundred and ninety-three。 在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand(千)和million(百万)来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。7.多位数的读法：1)1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand(千)，第二个间隔或逗号前是million(百万)，第三个间隔或逗号前是a thousand mi

47、llion或a billion(十亿)。2)每隔三位分段以后就都成了101999。读的时候十位数(或个位数)的前面一般要加and。如：888，000，000读作：eight hundred and eighty-eight million。(二)基数词的用法1.基数词的复数形式表示大量的数目。在这种情况下，表示单位的基数词(hundred, thousand, million, billion)不能在词尾加-s。例如：two hundred students 二百个学生five thousand years 五千年2.基数词的复数形式表示大量的 的数目，在这种情况下，表示单位的基数词词尾加-s

48、，要与of短语连用。3.基数词在句中的作用基数词的作用相当于名词和形容词，它在句子中可充当主语，宾语，表语和定语。例如：three and five is eight. 3+5=8主语 表语how many oranges do you want?你要多少桔子?i want eight. 我要八个。宾语there are eight boats in the lake. 湖里有八条小船。定语(三)序数词表示顺序的词，叫序数词。序数词用来表示数词顺序。除特殊情况外，序数词一般都由相应的基数词加后缀-th构成。请见下表：第一到第十 第十一到第十九 第二十以上first eleventh twent

49、iethsecond twelfth thirtieththird thirteenth fortiethfourth fourteenth fiftiethfifth fifteenth sixtiethsixth sixteenth seventiethseventh seventeenth eightietheighth eighteenth ninetiethninth nineteenth hundredthtenth thousandth说明：1.英语中表示第一、第二、第三的序数词属特殊形式，要注意它们的拼写。2.表示“几十”的序数词通常是将基数词词尾y变成i再加上后缀-eth。3

50、.其余的二位数序数词是以相应的整十基数词加个位序数词。如：fifty-first(第五十一)。4.少数序数词拼法不规则，如：fifth(第五)，eighth(第八)，ninth(第九)，twelfth(第十二)等。注意：1.序数词可缩写为阿拉伯数字加序数词最后两个字母。例如：第一：(the) first=1 st第二：(the) second=2 nd第三：(the) third=3 rd第五：(the) fifth=5th第九十七：(the) ninety-seventh=97 th第一百零一：(the) one hundred (and)first=101st2.编了号的事物要用基数词表示

51、顺序，但是基数词要后置。例如：第一课：lesson one第三十二页：page 32第305房间：room 305第12路公共汽车：bas no.12(四)序数词的用法序数词和基数词一样，也能起名词或形容词作用，在句子中作主语、表语、宾语和定语。例如：the first is bigger than the second. 第一个比第二个大。主语give me the first. 把第一个给我。宾语shes often the first to go to school. 她经常第一个去上学。表语were going to learn the eighth lesson. 我们将要学习第八课

52、。定语初中英语语法归纳：主动语态在初中的英语学习中，句子语态可以分为主动语态和被动语态两种。那么主动语态的句子需要有哪些语法要注意呢?主动语态和被动语态又会有什么区别呢?下面为大家讲解一下。主动语态与被动语态的区别：在主动语态中，主语后面接人(be +动词原型)被动语态(be+动词过去分词)在主动语态中，主语是谓语动词的使动方。在被动语态中，主语是谓语动词的受动方。在语法结构上，主动语态和被动语态的区别主要在于，主动语态直接使用动词原形作为谓语，然后再在该动词原形的基础上施加时态和其他语法;而被动语态则使用系词+动词的过去分词作为谓语，各种时态和其他语法也施加在系词上。举例：1.主动语态：th

53、e snowslide killed him. 雪崩害死了他。被动语态：he was killed by the snowslide. 他死于雪崩。2.主动语态：we use electricity to run machines. 我们用电力来开动机器。被动语态：electricity is used to run machines. 电力被我们用来开动机器。3.主动语态：bell invented the telephone in 1876.贝尔于1876年发明了电话。被动语态：the telephone was invented by bell in1876.电话是贝尔于1876年发明的

54、。主动形式表示被动意义大家都知道，用被动语态(形式)来表达被动意义，但有些句子用的却是主动形式，表达的却是被动意义。下面我们就来总结一下常见的用主动形式表示被动意义的几种形式。1.连系动词(如：feel,taste,sound,smell,look等)用主动形式表示被动意义。如：this material feels very soft. 这块材料摸上去很柔软。this apple tastes good. 这个苹果尝起来很好吃。2. 有些表示主语内在性质或性能的不及物动词常与一些副词连用，用一般现在时的主动形式表示被动意义，其主语一般为事物。这些动词有：sell,read, write,wash,wear,last等。如：the pen writes smoothly 这支笔写起来很流畅。this kind of food sells well. 这种食物很畅销。3. 动词need, want, require表示需要时，后接动名词或不定式的被动式表示
