七年级英语语法知识点汇总
一．字母和音标
1. 26个英文字母：5个元音字母a, e, i, o, u （联系汉语拼音中的韵母排列顺序
快速记忆）
2. 48个国际音标：20个元音组合，28个辅音组合。重点辨别相似发音的元音
组合。如：[ə] a China breakfast [e] ea head bread [ei] a name cake
二．十大词类
（一）名词
a. 专有名词和普通名词。专有名词指个别的人，事物，地点等专有的名称，如China, Gina. 普通名词如table, chair.
b. 可数名词和不可数名词：可数名词有复数形式，如an apple，two apples. 不可数名词一般没有复数形式，如milk, bread, rice.
[重点]可数名词的复数变形：有规则变化和不规则变化两种
规则变化：
1一般情况直接在词尾加 “-s”, 如: bag-bags, day-days, boy-boys, key-keys等。 ○
2以s, x, sh, ch结尾的单词，要在词尾加 “-es”, 如: bus-buses, watch-watches, ○
box-boxes等。
3以辅音字母加y结尾的单词，要变y为i再加 “-es”, 如：baby-babies, ○
country-countries, family-families等。
4部分以f (e)结尾的单词，要变f (e)为“ves”, 如：knife-knives, half-halves等。 ○
顺口溜：小偷(thief)的妻子(wife)，为了自己(self)保命(life)，站到架子上(shelf)，用树叶(leaf)做的小刀(knife)，将狼(wolf)劈成了两半(half)
5以字母“o”结尾的单词，没有生命的加“-s”,有生命的加“-es”,如：○
zoo-zoos, photo-photos, tomato-tomatoes.
口诀：黑人(Negro)英雄(hero)爱在火山(volcano)吃土豆(potato)西红柿(tomato)
不规则变化：
1改变单数名词中的元音字母：○man-men, woman-women, foot-feet, tooth-teeth等。
2单、复同形：sheep-sheep, fish-fish,cattle-cattle,deer-deer, Chinese-Chinese, Japanese-Japanese等。 ○
3其他形式如: mouse-mice, child-children,person-people,ox-oxen等.
4、一些名词虽分单数、复数，但出现次数多的总是单数词
例：abscence; clothing; film; help; furniture家具; machinery机械; news; scenery风景; sugar; traffic交通
5、另一些名词则以复数词出现的机会较多
例：bellows风箱; clothes; police; shorts短裤; scissors剪刀; spectacles眼镜; shears大剪刀 trousers长裤; wages工资
名词所有格：表示所属关系
1. 单数名词词尾直接加’s, 复数名词词尾没有s的也要加’s, 如the boy’s bag 男孩的书包 men’s room 男厕所 Children’s Day 儿童节
2. 若是复数名词词尾有s ，只加“ ’”, 如：Teachers’ Day 教师节
3. 如果两个名词并列，并且分别有’s，则表示“分别有”；只有一个’s，则表示“共有”，如：John’s and Mary’s room(两间) John and Mary’s room(一间)
（二）冠词
1. 定冠词the：特指某(些)人或某(些)物，如The blue shirt is mine. 蓝衬衫是我的。
2. 不定冠词a/an: 用来表示“一”这个数量, 其中an放在元音字母开头的名词
前面，如 an apple, an orange.
3. 零冠词: 不用冠词的情况。在专有名词，不可数名词，学科名称，三餐和球类运动名称前不用冠词，如：Tian’an Men Square天安门广场
（三）代词（人称、物主、反身代词）
物主代词：包括名词性物主代词和形容词性物主代词。前者用法相当于名词，在句中可单独使用，如：--Who’s book is this? --It is mine. 后者用法相当于形容词，在句中不可单独使用，如 It is my book.
反身代词：表示“自己”，“本身”。
指示代词
（四）数词
1. 基数词：表示数目的多少
2. 序数词：表示事物的先后顺序，往往与冠词the连用
基数词变序数词口诀：
一、二、三，单独记；八去t，九除e， ve要用f替，整十基数变序数，先把ty变成tie；要是遇到两位数，十位基数个位序，th最后加上去。
口诀解析：one→first， two→second， three→third这三个词变化特殊，要单独记；eight→eighth， nine→ninth， 八去t，九去e后再加-th； five→fifth， twelve→twelfth，五和十二把ve换成f再加-th；twenty→twentieth， thirty→thirtieth... 整十先把词尾y改为ie再加-th。两位数时则十位数用基数词，个位数用序数词，如：twenty-first。
注：four→fourteen→forty（基数词）
fourth→fourteenth→fortieth（序数词）
三．时态：
（一）一般现在时：
a.表示习惯性、经常性、反复性的动作或存在的状态b. 表示事实或客观真理。 结构：
1. be动词（am, is, are）的用法
记忆口诀： “我”用am, “你”用are, is用于“他、她、它”；单数全都用is，复数全部都用are.
句子转换：当句子中有be动词或情态动词时，则把be动词或情态动词(can, could等等)提到主语的前面变成一般疑问句；在be动词或情态动词后面加not变成否定句
陈述句：She is a student. 一般疑问： Is she a student? 否定句：She is not a student.
2. 实义动词do（除第三人称单数外，谓语动词用原形）
句子转换：当句子中既没有be动词，也没有情态动词时，则在主语前加助动词do (I, you, we, they), does（单数she, he, it）变成一般疑问句；在主语后谓语动词前加助动词don’t（I, you, we, they), doesn’t（单数she, he, it）变成否定句，助动词后的动词要变成动词原形.
陈述句：We get up at 7:00 every morning.
一般疑问句：Do you get up at 7:00 every morning?
否定句：We don’t get up at 7:00 every morning.
【重点】动词第三人称单数（三单）的规则变化
1. 一般在词尾加-s，如: looks, puts, reads, sees等。
2. 以-o, -s, -x, -sh, -ch结尾的加-es，如: goes, does, watches, teaches
3. 以辅音字母加y结尾的，变y为i再加-es. 注：若是元音字母加y，则直接加-s。 如：fly → flies, try → tries, fry → fries, copy → copies
buy → buys, enjoy → enjoys, play → plays, say → says, pay → pays
总结：三单的变化规律与可数名词复数的（前三种）变化规律相似。
（二）现在进行时：
1. 表示现在（说话的瞬间）正在进行或发生的动作，强调“此时此刻”。 如：He is reading . They are talking now.
2. 表示当前一段时间内的活动或现阶段正在进行的动作。
如：They are working on a farm these days.
3. 结构：动词be（am/is/are）+V-ing
V-ing形式构成：
1. 一般在动词词尾加上-ing，如go→going look→looking watch→watching
2. 以不发音字母e结尾的动词，先去e，再加-ing. 如write→writing take→taking
3. 以重读闭音节结尾，且末尾只有一个辅音字母时，要先将词尾的辅音字母双写再加ing，如run→running shop→shopping get→getting sit→sitting
（三）一般过去时：表示过去某个时间里发生的动作或状态；或过去习惯性、经常性的动作、行为（used to）；
1. 句子转换口诀：一般过去并不难，表示过去(动作、状态)记心间。 动词要用过去式，时间状语句末站。
如果动词是Be动词（was/were）,构成主系表的结构。
如果动词是实义动词或除be动词以外的其它连系动词，需要将句中的动词变为过去时
否定句很简单，didn't动词(原形)前，其它部分不要变。疑问句也好变，did放在句子前，其它部分依次站。
陈述句He(she, it) worked
疑问句Did he(she, it) work?
否定句He (she, it)did not work
2. 表过去的时间状语
如：ago, yesterday, the day before yesterday, last week, last (year, night, month, 具体时间)， just now, at the age of , one day, long ago, once upon a time(很久以前)
3. 动词变化规则：
规则变化：
a.一般情况直接加ed，如：work→worked look→looked
b. 以不发音的e结尾的，加-d，如：live →lived hope →hoped
c. 以辅音字母+y结尾的，变y为i加ed, 如：study→ studied
d. 以重读闭音节结尾的，末尾只有一个辅音字母，要双写最后的辅音字母加-ed，如： stop→ stopped plan→planned
特别提示：
1. 在清辅音后读／t ／ 如：helped stopped
2. 在元音或辅音后读／d ／ 如： stayed agreed
3. 在辅音／t ／，／d ／后读／id／ 如： wanted needed
不规则变化 ：过去时和原形相同， 如：cut→cut read→read
四．There be句型结构
1. 结构的主谓一致。There is/are+某物/某人+某地/某时表示某地或某时存在某事或某人。句子的结尾往往带有地点状语或时间状语。其中there是引导词，本身没有词意，be是谓语动 词，be后面的名词是主语。be的数与后面的名词一致，若be后是两个或多个并列的名词，be则与靠得最近的那个名词的数一致。如 There was a meeting yesterday. 昨天有个会议
比较：
There is a pen, two books and many pencils on the desk. 桌上有一支钢笔、两本书和好些铅笔。
There are two books, a pen and many pencils on the desk
2．there be的否定、疑问及其回答式
(1) 否定式：be后面加not(any)或no。如：
There are not any boats on the river. 河上没有船。
(2) 疑问句：把be移到there之前。如：
Were there many boats on this river? 过去这条河上有许多船吗？
回答：Yes, there were. / No, there weren’t.
五．句子种类
（一） 陈述句
陈述句的否定结构：
陈述句的否定式主要用两种结构来表达：
（1）句子的谓语动词为be , have 或者谓语动词有助动词、情态动词时，其否定结构为： 主语+谓语动词/助动词/情态动词 + not + 其他成分
I am not a teacher. 我不是老师。
We have not (haven`t) any books on animals. 我们没有任何有关动物方面的书。
The children are not (aren`t) playing in the playground. 孩子们没在操场上玩。
He will not (won`t) come. 他不会来。
We must not (mustn`t) forget the past. 我们不能忘记过去。
It could not (couldn`t) be lost. 它不可能丢的。
（2） 当句子的谓语动词是do (即行为动词)，而且没有助动词或情态动词时，其否定结构为：主语+do (does,did) + not + 动词原形 + 其他成分
You do not (don`t) come here every day . 你没有每天都来这里。
He does not (doesn`t) teach this class . 他不教这个班。
They did not(didn`t) watch TV last night . 昨晚他们没看电视。
注意：陈述句的语调一般用降调。但在表示疑问的语气时，用升调，在书面上要用问号来表示。
You really want to go to Hong Kong ? 你真的想去香港吗？
这句话表示的是一种疑问，只不过是通过陈述的语序和疑问的语气来表达的
（二） 疑问句
疑问句是用来提出疑问的句子，句末用问号―？‖。常考的疑问句有四类，即：一般疑问句、特殊疑问句、选择疑问句、反意疑问句。
第一节 一般疑问句
一般疑问句通常需要用yes 或no 来回答，所以又叫做―是非疑问句。在读这种句子时 要用升调。一般疑问句主要有以下几种类型：
1、―be + 主语 + 表语‖结构
— Are you sleepy ? 你困了吗？ — Yes, I am . 是的，我困了。
3、―情态动词 + 主语言+ 行为动词（或be）‖结构
— May/Can I use the telephone? 我能用这部电话吗？ — Yes, you can. 是的，可以。
5、―助动词（do, does, did）+ 主语 + 行为动词‖结构
— Do you like swimming in summer? 你喜欢夏天游泳吗？ — No, I don`t . 不，我不喜欢。 难点提示
回答否定性一般疑问句时，要在Yes 后面用肯定结构，表示肯定；在No 后面用否定结构，表示否定。注意在说法上正好与汉语习惯相反。诀窍是在回答的时候，只要把它当成没有加否定形式的普通一般疑问句看待就可以了。注意下面例句的回答和它的意思。
— Is he not your elder brother? 他不是你的哥哥吗？
—Yes, he is . 不，他是（我的哥哥）。No, he is not. 是的，他不是（我的哥哥）。 — Isn`t she very clever? 她难道不是很聪明吗？
— Yes, she is. 不，她很聪明。 — No, she is not . 是，她不聪明。
第二节 特殊疑问句
一、特殊疑问句是用来提出来特定问题的疑问句，要求听到问题的人针对特定情况来做具体的回答不能用Yes或No来回答的问句，句尾读降调。(由五个W一个H来引导特殊疑问句)
二、特殊疑问句的结构：
特殊疑问词 + 一般疑问句
Who do English homework in the evening?谁晚上做英语家庭作业？
What do you do in the evening?你晚上做什么？
What homework do you do in the evening?你晚上做什么家庭作业？
When do you do English homework?你什么时候做英语家庭作业？
三、注意：
对人提问时who―谁‖
对所属（谁的）提问用whose―谁的‖
对哪一个提问用which―哪一个‖
对时间提问用when―什么时候‖或what time―几点‖
对物体提问用what―什么‖
对地点提问用where―哪里‖
对原因提问用why―为什么‖
对方式提问用how―怎么样‖
对数量提问用how many―多少‖（用于可数名词复数）或how much―多少‖（用于不可数名词）
四、难点提示
1、 以why开头的特殊疑问句否定形式常用于表示建议、请求等。 Why don`t you have a try? 你为什么不试试呢？
2、 特殊疑问句常用到一些缩略形式，在平时学习中要注意习惯这些用法。
I don`t want to go there. How about you? 我不想去那儿，你呢？
But what else? 可是还有什么呢？
（三）祈使句：表命令、警告、提醒、建议、请求、叮嘱、号召等，谓语动词用原形。主语you通常省略，句末用叹号或句号。肯定式以动词原形开头，否定式在动词原形前加don’t. 如： Don’t arrive late for class. Practice the guitar every day.
为了表示礼貌，常在句首或者句末加please，在句末以“，”隔开。
如：come in，please. Please call me!
Let’s祈使句: 包括听话者本人在内，表示建议。如：Let’s go home. 我们回家吧！
（四）感叹句
感叹句是表达喜、怒、哀、乐以及惊奇、惊讶等强烈感情的句子。感叹句通常由 what 或 how 引导。"what"和"how"与所修饰的词置于句首，其它部分用陈述句语序。
打油诗一首
或what an
形后若是不可数或名复数
只用what就可以
形容词后乱糟糟
只写how就OK了
六．情态动词：是一种本身有一定的词义，表示说话人的情绪，态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成谓语。
can的基本用法：
1. 表示能力。I can speak English. 我会讲英语。
2. 表示许可。You can play football on weekends. 你可以在周末踢足球。
3. 表示请求。Can you help me? 你能帮助我吗？
must表示“必须”。 You must read a book before you watch TV.
have to表示“不得不”，“必须”，如We have to be quiet in the library. 二者区别：
1. must表示说话人主观的看法，have to往往强调客观需要。
如：I must go.
It is a little late and I have to go now.
2.否定意义不同：mustn’t 表示“禁止”，而don’t have to 表示“不必”。 You mustn’t talk to your mother like that.
You don’t have to come if you don’t want to.
3.must 没有人称和数的变化，但have to有
I/You/They must do it now.
She has to finish her homework today.
八．介词
介词是一种虚词，它不能单独担任句子成分，必须与名词或代词或相当于名词的其他词类、短语或从句构成介词短语，才能担任句子成分。
1. 表示时间的介词at，in，on
A. at：用于表示时刻、时间的某一点
at 6 o’clock 在6点 at lunch在午饭时 at breakfast早餐时
at noon正午时 at that time那时
B. on用于表示某天，某一天的上、下午（指具体的某一天，一律用on）
on Monday在周一 on Tuesday morning在周二早上 on June 6 在6月6日
C. in用于表示周、月、 季节、年和泛指的上午、下午、晚上（指在一段时间内） in the afternoon在下午 in the week在这周 in the holiday在假期中
D. for 后面跟一段时间： for two days/hours
2. 表示场所、方向的介词at，in，on
A. at在某地（表示比较狭窄的场所, 小地方） at school上学 at home在家
B. on在...上面，有接触面 on the desk 在桌子上面 on the map在地图上
C. in表示一个范围（大地方） in Beijing/China in the water
3.固定搭配
By+交通工具 by bus/ train/plane/bike/subway
重点：动词和介词的连用，如：
arrive at/in 到达 ask for 请求 get off 下车 listen to 听
help sb with sth 帮助某人做某事 talk about 谈论 look at 看；注视
附： 形容词、副词的比较级和最高级的用法： 当两种物体之间相互比较时，我们要用形容词或副词的比较级； 当相互比较的物体是三个或三个以上时，我们就要用形容词或副词的最高级。
