1．语态定义：英语中表示主语和谓语之间的关系的动词形式称为语态。英语的语态分为主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。We teach English in our school .(主动) English is taught in our school .（被动）
2．被动语态：助动词Be + 及物动词的过去分词（be +p.p.），be有人称、时态和数的变化。见下表：
时态谓语动词的形式例子
一般现在时Am / is / are + 动词过去分词Colour TVs are made in the factory .
一般过去时Was / were +动词过去分词My hometown was liberated in 1949 .
一般将来时Shall / will + be +动词过去分词The film will be shown again .

3．被动语态中值得注意的问题：
○1 带有双宾语的动词，可以把任何一个宾语变被动，一般在间接宾语前加适当的介词。My father gave me a book ./ I was given
a book by my father ./ A book was given to me by my father .
○2 英语中有些动词用主动语态表示被动语态。The cloth washes well ./ This kind of bags sells well. /
The shoes wear long. / The knife cuts well . / The pen writes smoothly . / This coat lasts long .
○3 在英语中有时“be + V-ed”结构并不是被动语态，而是系表结构。The mountains were covered with snow .
○4 在“主语＋谓语＋宾语＋宾语补足语”的结构中，要补留宾语补足语。We found the door broken. / The door was found broken.
○5 宾语补足语为省to的不定式，变为被动语态后，要还原to。He made me laugh. / I was made to laugh .
○6 如果短语动词是及物动词时，可以用被动语态，但不能遗漏所含的介词或副词。The nurse looked after the baby ./ The
baby was looked after by the nurse . / We must make up for the lessons we
missed. / The lessons we missed must be made up for .
○7 下列情况不能用被动语态：

句子的种类
1．英语中按使用目的或功用分为四类：陈述句、疑问句、祈使句、感叹句。
A．陈述句。
○1 陈述句说明一个事实或陈述一个人的看法。陈述句分为肯定陈述句和否定陈述句两种。a．陈述句的肯定式。I have already posted the photos. / They are students. / I must go now
. / He was reading a book at 8:00 last night.
b．陈述句的否定形式。
（1）谓语动词是系动词be, 助动词have, will, shall, be或情态动词，只须在其后面加not构成否定句。
She isn’t a student . / He hasn’t been to the Great Wall . / I can not swim . /
You will not go there tomorrow. / They aren’t sleeping .
（2）若谓语动词是实义动词，在实义动词前加上do not，第三人称单数现在时用does not，过去时用did not。
He didn’t send me an invitation .
（3）由具有否定含义的词never, nobody, hardly, little, dislike, seldom, few, too…to等构成的否定句。
Not all the books in our school library can be renewed .
B. 疑问句。
○1 疑问句提出问题。英语中有四种疑问句：一般疑问句、特殊疑问句、选择疑问句和反意疑问句。
a．一般疑问句：以一个助动词、情态动词、动词be或have开始，语调为升调，通常要求以yes或no回答的疑问句。
（1）一般疑问句的基本结构：
Be动词(is, am, are, was, were)+主语+表语…？
Have动词(表示“有”：have, has, had)+主语+宾语…？
情态动词(can, may, must等)+主语+行为动词或be…?
助动词(do, does, did)+主语+行为动词…？
助动词(shall, will, have, has)+主语+行为动词…？
（2）否定形式的疑问句，通常把助动词与not缩写，放在句首。构成回答：
Aren’t you a student? Yes, I am .(不，我是) No, I am not .(对，我不是)
b．特殊疑问句：以疑问代词who, what, whom, whose, which或疑问副词when, where, why, how 开头。
（1）如果疑问词在句中作主语或其修饰主语时，其语序如陈述句。Who is on duty today ? / Which book is yours .
（2）如果疑问词在句中不作主语或其修饰主语，用“疑问词＋一般疑问句”形式。Where have you been ?
c．选择疑问句：提出两种或两种以上的情况，供回答者选择，并由or连用，但不能用Yes 或no 来回答。
（1）疑问句＋选择成分1＋or＋选择成分2？Do you want coffee or cocoa ? / Are you an Englishman or an American ?
（2）特殊问句＋选择答案1＋or＋选择答案2？who runs fast, Tom , Mary or Li lei .
d．反意疑问句：陈述部分＋提问部分。
（1）◎前肯后否，前否后肯。◎前后人称、数和时态要一致，疑问部分要用代词。◎事实回答用Yes, 非事实回答用No .
◎前陈述句用降调，后问句用升调；如对前陈述句内容有把握，后问句也可用降调。◎如果前面陈述句中有否定词：hardly, little, few, never,
rarely, nothing, none , nobody, not, no 等，后面疑问句应该用肯定式。
（2）陈述句中有：have to, had to, ought to, used to, don’t(imperative), somebody / someone, everybody / everyone时，附加疑问句需分别用：don’t, didn’t, shouldn’t, usedn’t / didn’t, will, they等。
My grandma used to be a teacher, usedn’t / didn’t she? Don’t turn on the TV set, will you ?
（3）陈述句部分是复合句时，提问部分的主语和助动词要与主句一致。He was reading when the teacher came in, wasn’t he ?
（4）在“I think(guess, suppose, believe)+宾语从句”中，当主语是第一人称时，附加疑问句的主语和谓语应与后面宾语从句相一致；但若主语不是第一人称时，则附加问句与前面主句
一致。
I don’t think he can pass the exam, can he ? He believed you had seen her before, didn’t he ?
（5）在含有情态动词must 的句子中，若must 表示推测，提问用must后面的动词。若must 表示有必要时，用needn’t。若mustn’t表示禁止时，提问用must。
He must be tired, isn’t he ？You must go to Gaozhou, needn’t ？You mustn’t smoke here, must you ?
（6）陈述句部分为祈使句，疑问部分常用will you(表请求)。注：let’s 用shall we（包括说话人），let us 用will
you（不包括说话人）。Have a cup of tea, will you ? Let’s go now, shall we ? Let us go now, will you ?
e．祈使句：可表示请求、命令、劝告、建议等。（省主语，动词用原形）

句子类型
1．从结构上看，英语的句子可分为三种类型：简单句、并列句和复合句。
2．简单句：由一个主语（或并列主语）和一个谓语（或并列谓语）构成的句子叫做简单句。简单句有六种句型：
型号句型例子
1 主语＋不及物动词（＋状语）The Frenchman coughed badly at night. / The city lies in a valley .
2 主语＋连系动词＋表语That is a map of China. / That piece of meat looks quite good. / It sounds like the singing of rails .
3 主语＋及物动词＋宾语You’re doing the right thing. / Jack likes to stay at home and play
by himself .
4 主语＋及物动词＋间接宾语＋直接宾语Can you tell me the way to the Summer Palace ? / It took me a week to finish the work.
5 主语＋及物动词＋宾语＋宾语补足语We call him Li Ming . / The rich man asked the singer to come up to the sitting room .
6 There +be+主语＋状语There are some flowers on the teacher’s desk . / There are 365 days in
a year .
3．并列句：由并列连词把两个以上的简单句连在一起构成的句子。常用的并列连词有and, but, for, or, nor, so, yet, neither…nor, either…or, still, however, not only…but also等。并列句的结构：简单句＋并列词＋简单。
Hurry up, or you’ll miss the early bus . / We love peace but we are not afraid
of war . / He must be ill, for he is absent today .
She has not only kn owledge, but also experience . / He was ill, so he didn’t go
to school. / Work hard, and you will succeed .
4．复合句：由一个主句和一个或一个以上的从句构成的句子叫做复合句。主句是句子的主体，从句只用作句子的一个成分，不能独立。从句可以担任复合句的主语（主语从句）、表语（表语从句）、宾语（宾语从句）、定语（定语从句）、状语（状语从句）。中学阶段主要学习含有状语从句、宾语从句、定语从句的复合句。
A．状语从句：在复合句中修饰主句中的动词、形容词或副词等的从句叫做状语从句。状语从句根据它表示的意思的不同可分为时间、地点、原因、结果、让步、比较（或方式）和条件等类。
○1 时间状语从句：由when, while, as, the moment, the minute, once, whenever, before, after, till(until), since, as soon as等连词引导。
主句从句例子
一般将来时一般现在时I will go out for a walk if it doesn’t rain tomorrow .
带有情态动词You must look left and right when you cross the crossing .
祈使句Ask him to give me a call as soon as he comes back .
过去时的某种时态过去时的某种时态I went to bed at ten after the film was over. / The film had begun when I reached the cinema .
I was reading a book while he was singing a song .
○2 条件状语从句：由if, unless, so long as, as long as, in case , if only, provided
that等引导。（注：在条件状语从句的将来时态要用现在时和过去时，表示相应的将来时）。I’ll show you around the city if I am free tomorrow . / If I had en ough money, I would buy the car .
○3 原因状语从句：由because（因为）, as（由于）, since（既然）, for（因为）等引导。He was absent yesterday because he was ill . / As it was already dark, they
decided to stay in the town for the night .
○4 目的状语从句：由so that, that, so, in order that, in case等引导。句中常有may, might, can, could, should, would等情态动词。
He got up early so that he could catch the early train. / He studied hard in order that he might succeed .
○5 结果状语从句：由so…that, so, so that, such…that等。
The film is so interesting that everyone likes to see it again . / Nothing more
was heard of him, so people thought that he was dead .
○6 比较状语从句：由than, as…as, not as(so)…as, the（＋比较级）…the（＋比较级）等引导。
Today is not as warm as yesterday. / He listens to the teacher more carefully than I .
○7 地点状语从句：由where 和wherever等引导。地点状语从句位于句首时，常用逗号与主句隔开；位于句末时则不用逗号。
He follows her wherever she goes .
○8 方式状语从句：由as, just as…so, as if 等。As if 引导的从句的时态要用过去时（虚语语气）。
Please do as I do . / He tells me the whole thing as if he knew everything .
○9 让步状语从句：由though, although, even if, even though, however, whatever, no matter who等引导。
Although he has failed many times, he doesn’t give up trying .
B．宾语从句：由一个句子充当宾语，我们称之为宾语从句。（宾语从句的语序永远是陈述语序）
○1 宾语从句的连词。
a．如果宾语从句是从陈述句变化而来的，要用连词that来引导，that可以省略。
b．如果宾语从句是从一般疑问句变化而来的，要用连词if或whether .
c．如果宾语从句是从特殊疑问句变化而来的，连词就应该用特殊疑问词（what, when, where…）。
○2 宾语从句的时态：
主句从句例子
任何一种时态一般现在时（表示真理、科学原理、自然现象）The teacher told / tells us that the earth goes
round the sun.
一般现在时任何一种时态I hear that he will come back next week.
一般将来时I will tell him that his father rang him up just now when he comes back .
一般过去时过去时的某种时态I wondered if Tom would come back ./ Lucy asked whether I had
finished my homework .
○3 宾语从句的人称：人称代词要随合理的逻辑而自然变化。
She said, “I am much better than before.”--------She said that she was much
better than before .
○4 when 和if 在引导宾语从句和状语从句中，后面的时态有差别。
I don’t know when (何时)she will be back（宾语从句）, but when(当…时候) she comes back, I’ll let you know（状语从句）.
I don’t know if(是否) she will come back（宾语从句）, but if (如果)s 共有4条文章:
he comes back, I’ll let you know （状语从句）.
C．定语从句：在复合句中修饰名词或代词的从句叫做定语从句，被定语从句修饰的名词或代词叫先行词，定语从句必须放在先行词之后。引导从句的关系代词有：who(人，主格), whom(人，宾客), whose(人，所有格), which(物), that(人，物)。引导从句的关系副词有：where(地点), when(时间), why(原因)。
The man who lives next to us is a policeman./ You must do everything that I do
./ We will never forget the day when we visited Gaozhou .
主句/先行词从句主句主句/ 先行词从句主句/ 先行词从句
○1 从句的谓语动词和先行词的关系。
a．主谓关系：He asked the man(作从句主语) who/that was smoking .
b．动宾关系：The noodles(作从句宾语) that/which I cooked were delicious .
○2 只能用that 的情况：
a．先行词为all, any, few, no, some, much, little等修饰。I have done all the work that he told us to do .
b．先行词被序数词修饰。That last/first question that he asked me was hard to answer . c．先行词同时有人和物。They often talk about things and persons that they remember . d．先行词是everything, anything, nothing, none等不定代词。I remembered everything that the teachers taught me before .
e．先行词被形容词最高级修饰。That is the best book that I have read .
f．先行词被the very, the only, the same修饰。It is the very book that I am looking for
g．先行词是主句的表语或关系代词在定语从句中作表语。China is no longer the country that it used to be .
h．先行词是指示代词that, one, those, this, another, all等。Is this school the one that I saw in the picture ?
i．主句以who / which开头，定语从句用that 。who is the girl that spoke to you just now ? / which is the car that was made in China ?
○3 只能用which的情况：
a．关系代词前有介词。This is the house in which we lived last year .
b．先行词本身是that 。The clock is that which I bought yesterday .
c．非限制性定语从句。His English , which used to be very poor, is now excellent .
○4 定语从句在句中作定语，所以在使用时，相当于现在分词短语，过去分词短语，动词不定式短语，介词短语作后置定语的句子。
a．I bought a book that was written by Lu Xun . = I bought a book written by Lu Xun .
b．Tell the children who are playing basketball not to do that . = Tell the children playing basketball not to do that .
c．The house that stands at the corner was built in 1987 . = The house standing at the corner was built in 1987 .
d．We have nothing that we should fear . = We have nothing to fear .
e．The book that is on the table is expensive . = The book on the table is expensive .
○5 引导词when, where和why可用相应的表示时间（in, on, at, during等）、地点（in, on, at等）和原因（for）的介词＋which 表达为介宾结构。
a．I still remember the day when I met her for the first time . ---- I still
remember the day on which I met her for the first time .
b．That is the place where I went when I was a child . ----- That is the place to which I went when I was a child .
c．May I know the reason why you are late ? ----- May I know the reason for which you are late ? ○6 在定语从句中，不能再出现指示先行词的指示代词。
I just can’t find the book which/that she lent it to me .（×）---- I just can’t
find the book which/that she lent to me .（√）
○7 注意下面的变化：
a．This is the house(不作lived的宾语) where we lived last year .
This is the house(作lived in的宾语) which/that we lived in last year .
b．This is the day (不作left的宾语)when we left for Shenzhen .
This is the day (作spent的宾语)which/that we spent in Shenzhen .
○8 限制性定语从句和非限制性定语从句的区别：
a．限制性定语从句：是句中不可缺少的组成部分，没有从句，先行词意思不明确，主句也不完整，从句主句不用逗号分开。
b．非限制性定语从句：是主句先行词的补充说明，没有从句并不影响主句意思的明确或完整，这种定语从句一般用逗号和主句分开，在非限制性定语从句中，一般不用that。
◎Last Sunday they reached Dalian, where a meeting was to be held .
◎She has two brothers, who are both doctors .
ⅢThere be 句型
1．英语“There + be + (not)”结构表示“有（没有）某人或某物”时，there
是无词义的引导词，be是谓语动词，它后面的名词是主语，两者再数上必须一致。句末往往有表示地点或时间的状语。
2．肯定句：There +(助动词或情态动词)＋be 主语＋地点（时间）状语。
There is a pen on the table . / There will be a football match tomorrow .
3．否定句：There + be(助动词或情态动词)＋not（any）(或＋no)+ 主语…。

before ./ There won’t be a football match tomorrow .
4．一般疑问句：Be + there +(any) +主语…？/ 助动词或情态动词＋there +be +(any) + 主语…？
Is there anything I can do for you ? / Will there be cloud tomorrow ?
5．特殊疑问句：疑问词（＋名词）＋be ＋there + 状语？
How many weeks are there in a year ? / What is there on the desk ? / Where will there be a football match tomorrow ?
6．如果there +be 之后是并列主语，应根据离be 最近的名词来选择be的形式。
There is a apple and two pears on the table . / There are two pears and a apple on the table .
7．含有引导词there 的句子用seem to be , happen to be , used to be 或live 等作谓语的结构。There happened to be an old friend of mine in the shop . / There used to be a temple here .
Ⅳ主谓一致
1．主谓一致是指谓语动词要与主语单、复数形式及人称变化相一致。主要包括三方面：形式一致、意义一致、就近原则。
2．单数名词、不可数名词作主语，谓语用单数；复数名词作主语，谓语用复数；若主语表示单数或整体概念时，谓语应用单数。

英语虚拟语气语法归纳总结
虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping. 附注： 虚拟语气，条件状从倒装 状语从句中，去掉if,提前were/ had/ should 如：If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）
英语名词知识点讲解
Less on 1 名词 定义：名词(noun)，缩写为n.是人和事物的名称，如pen(钢笔),English(英语)，life(生活)。1名词的分类 名词可以分为专有名词( Proper Nou ns)和普通名词(Com mon Nou ns ),专有名词是某个(些)人，地方，机构等专有的名称，如Beiji ng. Ch ina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(In dividual Nou ns):表示某类人或东西中的个体，如：gun。 2) 集体名词 (Collective Nou ns):表示若干个个体组成的集合体，如：family。 3) 物质名词(Material Nou ns ):表示无法分为个体的实物，如: air。 4) 抽象名词(Abstract Nou ns):表 示动作、状态、品质、感情等抽象概念，女口：work。个体名词和集体名词可以用数目来计算，称为可数名词( Cou ntable Nou ns ),物质名词和抽象名词一般无法用数目计算，称为不可数名词( Uncoun table Nou ns )。归纳一下，名词的分类可以下图表示：
3、名词复数的不规则变化 1）c hild---children foot---feet tooth---teeth mouse---mice man---me n woma n---wome n 注意：与man和woman构成的合成词，其复数形式也是-men和-women。 女口：an En glishma n， two En glishme n. 但Germa n 不是合成词，故复数形式为Germa ns ；Bowman是姓，其复数是the Bowmans。 2 ）单复同形女口： deer，sheep，fish，Chinese, Japanese li，jin，yuan，two li，three mu，four jin 但除人民币元、角、分外，美元、英镑、法郎等都有复数形式。女口： a dollar, two dollars; a meter, two meters 3 ）集体名词 只在动词使用时区分，如果将名词所表示的集体是为一个整体，则位于动词用单数; 如果将名词表示的集体是为分散的个体，位于动词则用复数。如： The class is small.这是小班。 The whole class are working very hard at English.这个班上的学生学习英语很刻苦。 4）以s结尾，仍为单数的名词，如： a. maths，politics，physics等学科名词，为不可数名词，是单数。 b. news是不可数名词。 c. the United States，the United Nations 应视为单数。 The Uni ted Natio ns was orga nized in 1945.联合国是1945 年组建起来的。 d. 以复数形式出现的书名，剧名，报纸，杂志名，也可视为单数。 "The Arabian Nights" is a very interesting story-book. <<一千零一夜>>是一本非常有趣的故事书。

中考英语语法知识点总结讲解(上)
中考英语语法知识点总结讲解（上） 第1讲：名词 First, 名词复数的特殊变化。 普通名词的复数我们知道是直接加-s或-es，可是偏偏有一些名词不听话，变化不规则。这些小调皮是： a. class, box, watch, brush等词以s, x, ch, sh, 结尾，复数要加-es； b. story, factory 等以辅音字母+y结尾的词复数要先将-y 变成-i再加-es； c. knife, wife, life等以-f 或-fe结尾的词一般先将-f或-fe变为-v, 再加-es； d. 以-o结尾的名词，一般来说，末尾是元音字母+o 的词加-s，我们学过的有radio,zoo。末尾是辅音字母+o的词，变复数加-es。如：tomato, hero, potato，当然其中的piano 和photo，又是一个例外，他们的结尾只能加-s。 e. child（children）, foot（feet）, tooth（teeth）, mouse（mice）, man （men ）, woman（women ）等词的复数变化全不遵循规则。 注意：与man 和woman构成的合成词，其复数形式也是-men 和-women。如：an Englishman，two Englishmen. 但German不是合成词，故复数形式为Germans； f. deer，sheep等词更是懒得可以，竟然单复数同形。好记好记。people，police，cattle 等词，以单数形式出现，但实为复数，所以它们的谓语当然也是复数形式，这就是集体名词。the English，the French，the

初中英语语法三大从句汇总重点笔记知识讲解
精品文档 初中英语语法——三大从句汇总 在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。以下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词，并且在定语从句中充当句子成分，可
以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （一）关系代词who, whom和 whose的用法 who代替人，是主格，在定语从句中作主语。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。 精品文档． 精品文档 I will never forget the teacher who taught us chemistry in the first year of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。 whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。例如：
