初中英语语法知识点总结
漫长的学习生涯中,大家都没少背知识点吧?知识点是知识中的最小单位,最具体的内容,有时候也叫“考点”。还在苦恼没有知识点总结吗?下面是小编帮大家整理的初中英语语法知识点总结,希望能够帮助到大家。
初中英语语法知识点总结1
名词的所有格:表所有关系
两种表示法:’s和of
1)用and连接两个并列的单数名词表示共有关系时,只在最后一个名词后加’s;表示分别拥有各自的物品时,两个名词都要加’s.
eg: Mary and her sister’s bedroom 玛丽和她妹妹的房间 Tom’s and Mary’s bags 汤姆的和玛丽的包
2)以s结尾的名词,在s后加’, 不以s结尾的加’s
eg: Teachers’ Day Children’s Day
3)双重所有格,形式:of+名词所有格;of+名词性物主代词
eg:He is a friend of my brother’s. Is she a daughter of yours ?
辨析: a picture of her mother’s 她妈妈的一张照片(强调照片是她妈妈的,但照片上的人不一定是她妈妈)
a picture of her mother 她妈妈的照片(强调照片上的人是她妈妈)
4)表示店铺、医院、诊所、住宅等名称时,常用名词后加上’s代表全称 at the doctor’s 在医院的候诊室
5)在some, any, every和one, boby结合起来的复合名词后加’s
someone’s book 某人的书, somebody else’s pencil 其他人的铅笔
6)表示时间,距离,国家,城市等无生命的名词,也可以在词尾加’s或’构成所有格。
意:名词+of+名词名词是有生命的,我们就用’s结构来表示所有关系。如果名词所表示的事物是无生命的,我们就要用名词+of+名词的结构来表示所有关系.如: the legs of the desk,the door of the room
但在表示名词所有格时,’s结构也常可转换成of结构。有些表示时间,距离、国家、城市等无生命的东西的名词,也可以加’s来构成所有格.如: ten minutes' walk,today's newspaper

初中英语语法知识点总结3
一、陈述句
陈述句是陈述一个事实或者说话人的看法的,陈述句分为肯定句和否定句。陈述句句末用句号,朗读时用降调。
1、肯定句的基本结构为:主+谓 He went to London to pass his holiday.
2、否定句的表达方式
(1)主语+be+not+表语 He is not a teacher.
(2)主语+助动词/情态动词+not+谓语动词+其他 I don't think you are right. He hasn't yet paid the money. (他尚未付钱。)
(3)使用“not”以外的否定词:
(a)副词:never, seldom, hardly, little, neither等。She seldom comes to see me. (她不常来看我。)
(b)形容词:no, few, little等 He has few friends in Hong Kong. (他在香港几乎没有朋友。)
(c)代词:nothing, nobody, none等。I found nobody about computer. (在那栋房子里我没看到任何人。)
二、疑问句
疑问句的主要交际功能是提出问题,询问情况。分为一般疑问句、选择疑问句、特殊疑问句和反意疑问句。
1、一般疑问句通常用来询问一件事情是否属实。答句通常是“yes或no”。 句型一:Be +主语+ …?Are these books on the desk?这些书在桌子上吗?
句型二:Do / Does / Did + 主语 +谓语+…?Do you like English?你喜欢英语吗? 句型三:情态动词 + 主语 + 谓语 +…?
Must I finish my homework now?我必须现在完成我的家庭作业吗?
句型四:Have / Has + 主语 + 过去分词+…?
Have you heard from him? 你收到他的来信吗?
另外,还有以be动词、助动词或情态动词的否定缩写形式开头的一般疑问句,这种句子一般表示请求、惊讶和对事物的看法等,回答时所用的yes和no表达的意思和汉语的习惯不同。例如:——Isn't he tall?难道他不高吗?
—— Yes, he is.不,他很高。
2、特殊疑问句以疑问词开头,对句中某一成分提问的句子叫特殊疑问句。常用的疑问词有:what 、who 、whose 、which、 when、 where、 how 、why等。例如: who is singing in the room?
what class are you in﹖
初中英语语法知识点总结4
初中英语语法常用
1)在代词what, which, who, none, some, any, more, most,all等词的单复数由其指代的词的单复数决定。
All is right. (一切顺利。)
All are present. (所有人都到齐了。)
2)集体名词作主语时,谓语的数要根据主语的意思来决定。如family, audience, crew, crowd, class, company,committee等词后用复数形式时,意为这个集体中的各个成员,用单数时表示该个集体。
His family isn't very large.他家不是一个大家庭。
His family are music lovers.他的家人都是音乐爱好者。
但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。
Are there any police around?

The number of +名词复数+单数动词。
A number of books have lent out.
The majority of the students like English.
初中英语语法口诀
一、冠词基本用法
名词是秃子,常要戴帽子,
可数名词单,须用a或an,
辅音前用a,an在元音前,
若为特指时,则须用定冠,
复数不可数,泛指the不见,
碰到代词时,冠词均不现。
冠词是中考必考的语法知识之一,也是中考考查的主要对象。以上口诀包括的意思有:
①名词在一般情况下不单用,常常要和冠词连用;
②表示不确指的可数名词单数前要用不定冠词a或an,确指时要用定冠词the;
③如复数名词表示泛指,名词前有this,these,my,some等时就不用冠词。
二、名词单数变复数规则
单数变复数,规则要记住,
一般加s,特殊有几处:
/s/结尾,es不离后,
末尾字母o,大多加s,
两人有两菜,es不离口,
词尾f、fe,s前有v和e;
没有规则词,必须单独记。
①大部分单数可数名词变为复数要加s,但如果单词以/t/、/y/、/s/发音结尾(也就是单词如果以ch,sh,s,x等结尾),则一般加es;
②以o结尾的单词除了两人(negro,hero)两菜(tomato,potato)加es外,其余一般加s;
③以f或fe结尾的单词一般是把f,fe变为ve再加s;
④英语中还有些单词没有规则,需要特殊记忆,如child—children,mouse—mice,deer—deer,sheep—sheep,Chinese—Chinese,ox—oxen,man—men,woman—women,foot—feet,tooth—teeth。
初中英语语法:句型转换
Ⅰ.题型介绍
所谓“句型转换”就是先给一个完整的句子A,再根据括号内的要求(有时没有明确,须自己观察),在第二个句子B的'空白处填上适当的词来完成的句型转换。
Ⅱ.题型分类
从形式上看,有如下几种形式:
①某一词或词组的转换;
②词组与句子的转换;
③同义句型的转换;
④为纠正常犯语言错误而设计的题目。
从内容上看,此题型涉及的面较广,主要有:
①句子功能方面的转换。包括陈述句(肯定与否定)、四种题疑问句、祈使句、感叹句的转换;
②句子结构方面的转换。即简单句、复合句、并列句之间的转换;
③语态的转换。即主动语态与被动语态之间的转换;④常用句型与词汇手段的转换。
Ⅲ.具体分类如下
一、陈述句与疑问句、祈使句、感叹句间的转换
1、陈述句中肯定句变为否定句,大部分是用not来改变谓语结构,但也有借用否定意义的词,如nothing, nobody, none, neither,little, few, never, hardly等,例如::
A:Tom does well in maths.
B:Tom doesn't do in maths.
A:He has much to do.
B:He has nothing to do.
A:All of my classmates like art.
B:None of my classmates likes art.
2、改为疑问句。根据上下句的结构和词的减少,来判断变为哪一种形式的疑问句。例如:
A:My brother often has breakfast at school.
B:Does your brother often have breakfast at school?
A:Tom's already weak in English.
B:Tom's already weak in English, isn't he ?
A:The red light changes every two minutes.
B:How often does the red light change?
3、改为感叹句。根据所给的句子结构和单词的词性,来确定使用哪一种感叹句的形式,例如:
A:This is an interesting book.
B:What an interesting book this is!或How interesting this book is!
初中英语语法知识点总结5
表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中。
1、虚拟语气的构成
如:与现在事实相反
If I had more time, I should study German.(fact:I have no more time, so I shall not study German. )
If she were not so busy, she would attend the meeting this afternoon.(fact:she is very busy, so she will not attend the meeting this afternoon.)
If they didn’t take physical exercises every day, they wouldn’t be so healthy.(fact: they take physical exercises every day, so they are very healthy.)
与过去事实相反:
I would have checked my paper again if I had had more time at yesterday’s examination.(fact:I had no more time at yesterday’s exam, so I didn’t check my paper again)
You would have already recovered from his illness if he had seen the doctor in good time.(fact: He didn’t see the doctor in good time ,so he hasn’t recovered from his illness )
与将来事实相反:
If it rains tomorrow, our picnic will be put off.(The weather has been changeable these days.)
If it rained tomorrow, our picnic would be put off.( The weather has beenvery good these days.)
If it should rain tomorrow, our picnic would be put off.(That would be out of our expectation.)
If it were to rain tomorrow, our picnic would be put off. (条件从句谓语动词用were to +动词原形,表示下雨的可能性极小。Were to rain和should rain都表示“出乎意料之外”,但were to加强表示“当初没想到以后的事”)
注:
(1)如果条件从句谓语动词包含有were或had, should, could有时可将if省去,但要倒装。如:
Had you (If you had) invited us, we would have come to your party.
(2)混合时间条件句的用法:
有时条件从句的动作和主句动作发生的时间不一致。这时动词的形式,应根据它所要表达的具体时间来决定用什么形式。
1) If she hadn’t trained so hard, she wouldn’t be run so fast.(从句叙述过去,主句叙述现在。)
(fact: she has trained very hard, so she would able to run fast.)
2)You would speak English well enough if you had practised reading and speaking it every day.(主句叙述现在,从句叙述过去)
(fact: You didn’t practice (hasn’t practiced ) reading and speaking it every day, so you can’t speak English well enough.)
(3)在其他状语从句中的用法
主要用于由as if (as though)引导的比较状语从句,从句中谓语动词一般用“动词的过去式(be变were )或had +过去分词。”如:
She looked as if she were ill.(实际上她没有病,在这里用虚拟语气补语比喻她精神不佳)
Xiao Liu speaks English so well as if he had studied in England.(这里用虚拟语气表现他的英语说得好)
2、虚拟语气在各种从句的应用
(1)在主语从句中用来表示惊奇、惋惜、理应如此等,其谓语形式是"should(可省) +动词原形",常用于以下三种句型中。
句型一:It is necessary (important, natural, strange, etc) that…
句型二:It is a pity (a shame, no wonder, etc) that…
句型三:It is suggested (requested, proposed, desired, etc) that…
如:It is strange that he (should) have done that.
It is a pity that he (should) be so careless.
It is requested that we (should) be so careless.
(2)在宾语从句中用于suggest, propose, move, insist, desire, demand, request, order, command等动词后的宾语从句中,表间接的命令和建议。其谓语形式是"(should)+动词原形"。如:
I suggest that we (should) go swimming.
(3)在表语从句中,表示间接的命令,要求、请求、建议、决定等,主句中的主语通常是suggestion, proposal, request, orders, idea等。从句谓语形式是"(should)+动词原形"。如:
His suggestion is that we (should) leave at once.
(4)在同位语从句中,谓语形式是"(should)+动词原形"。如:
We received order that the work be done at once.
(5)在It is time that…句型中,其谓语动词形式是"动词的过去式"或"should +动词原形",should不可省。如:
It's time (that) we went ( should go) to school.
初中英语语法知识点总结6
在习惯上只用作定语的形容词
这里说的定语指的是位于名词前作定语(即前置定语),而不是位于名词后作定语(即不用作后置定语),如main 是定语形容词,可以说mainthings,但不能说something main,因为后置定语从本质上说相当于表语,即something main 从本质上说相当于somethingthat is main。下面是几类典型的定语形容词:
一、表示相对关系的形容词
former 以前的,从前的 latter 后期的,后半的
inner 内部的,里面的 outer 外部的,外面的
upper 上部的,上游的 lower 下部的,下游的
elder 年岁较大的 eldest 最年长的
indoor 室内的,屋内的 outdoor 室外的,屋外的
inside 里面的,内侧的 outside 外面的,外侧的
upstairs 楼上的 downstairs 楼下的
inside, outside, downstairs, upstairs等既可用作形容词也可用作副词。用于形容词时,只用于名词前作定语;若用作副词,则可用作表语(或名词后作定语)。
二、表示强调意义的形容词
mere 仅仅的 very 极端的
outright 完全的 thorough 十足的
plain 完全的 complete 彻底的
pure 完全的 perfect 全然的
若用于其他意义,有的可用作表语,如plain表示“明白的”、“普通的”等均可用作表语;perfect表示“完美的”、“完备的”、“准确的”等,也可用作表语。
三、表示度量的复合形容词
three-year-old 3岁大的 120-page 120页的
five-year 5年的
若用作表语或后置定语,则不用连字符:
She has a five-year-old son. 她有一个5岁的儿子。
Her son is five years old. 她的儿子五岁。
She has a son five years old. 她有一个5岁的孩子。
八种宾语从句不省略that
引导宾语从句的that在下列情况下一般不省略:
1. 宾语从句前有插入语。如:
We hope, on the contrary, that he will stay at home with us.恰恰相反,我们希望他和我们呆在家里。
2. 有间接宾语时。如:
He told me that he was leaving for Japan. 他告诉我他要去日本。
3. that在与之并列的另一个宾语从句之后。如:
He said (that) the book was very interesting and that(不省略) all the childrenlike to read it.他说那本书很有趣,所有小孩都喜欢读。
4. 在“it(形式宾语)+补语”之后时。如:
I think it necessary that he should stay here. 我们认为他有必要留在这里。
5. that从句单独回答问题时。如:
—What did he hear? 他听说了什么事?
—That Kate had passed the exam. (他听说)凯特考试及格了。
6. 在except等介词后。如:
He has no special fault except that he smokes toomuch.他除了抽烟太多之外,没有什么特别的毛病。
7. 位于句首时。如:
That our team will win, I believe. 我相信我们队会赢。
8. 在较为正式或不常用的动词(如reply, object)后。如:
He replied that he disagreed. 他回答说他不同意。
if与whether的区别
1. 引导主语从句并在句首时不用if。如:
Whether we go there is not decided. 我们是否去那里还没决定。
2. 引导表语从句时不用if。如:
The question is whether we can get there on time. 问题是我们能否按时到达那里。
3. 引导同位语从句时不用if。如:
He asked me the question whether the work was worth doing.他问我这个问题,那项工作是否值得做。
4. 在介词后引导宾语从句不用if。如:
I’m thinking about whether we’ll have a meeting. 我在考虑我们是否要开个会。
5. 直接与not连用时不用if。如:
I don’t know whether or not you will go. 我不知道你是否去。
6. 宾语从句置于句首时不用if。如:
Whether you have met George before, I can’t remember. 我不记得你以前是否见过乔治。
7. 在discuss等之后时不用if。如:
We’re discussing whether we’ll go on a picnic. 我们在讨论是否要去野餐。
8. 当用if会引起歧义时不用if。如:
Please let me know whether you are busy.请告诉我你是否忙。(若用if,还可理解为“如果你很忙,你就告诉我。”

动词的种类
动词是表示动作或状态的词,按其词义和在句子中的作用可分为行为动词,连系动词,助动词和情态动词。
1.行为动词
行为动词可分为及物动词 (vt)和不及物动词(vi),及物动词表示动作或状态,有完整的词义,能单独作谓语,后跟宾语;不及物动词表示动作或状态,有完整的词义,能单独作谓语,但后面不能直接跟宾语,如要带宾语则与介词或副词构成短语。
如:
More and more people study English.(vt)
The students are listening to the teacher carefully.(vi)
2.连系动词
连系动词本身有一定的词义,但不能独立作谓语,必须与表语一起构成谓语。常用的连系动词有 be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。
如:
Our country is becoming stronger and stronger.
It feels damp.
3.助动词
助动词本身无词义,不能单独作谓语,只能和主要动词一起构成谓语动词,表示否定,疑问及动词的时态、语态、人称和数等语法特征,助动词有 be,do,have,shall,will等。
如:
How do you usually come to school?

a. can与be able to的用法有所区别。can只用于一般现在时和过去时,指本身有能力的"能";be able to用于各种时态均可,指须经过努力而"能"。
