今天整理了中小学英语8大中枢语法常识点,从最基础的东谈主称代词,一步步过渡到句子结构,按学习法度拆解,每一个常识点齐配了口诀、例子,非论是家长教导孩子,照旧学生我方查漏补缺,平直纳藏就能用,再也毋庸翻厚厚的教材啦!

话未几说,干货平直上

一、东谈主称代词 & 物主代词(语法入家世一关)

这是英语语法的基础,中枢是“代替东谈主/物,幸免重迭”,分为东谈主称代词和物主代词两类,重心差别主格、宾格,以及描写词性、名词性物主代词。

1. 东谈主称代词(主格 & 宾格)

简便说:主格放句首,作念算作的发出者;宾格跟在动词、介词后头,作念算作的承受者。

记挂口诀: 主格放句首作念主语,宾格跟在动词、介词后。

例句:

- I love English.(I是主格,放句首,“我”是算作的发出者)

- She helps me.(me是宾格,跟在动词helps后头,“我”是算作的承受者)

2. 物主代词(描写词性 & 名词性)

中枢作用:暗意“……的”,差别两种模样的要津的是“后头是否加名词”。

(1)描写词性物主代词:后头必须加名词 ,尽头于“描写词+名词”,不行单独使用。

常见词汇: my(我的)、your(你的/你们的)、his(他的)、her(她的)、its(它的)、our(咱们的)、their(他们的)

例句:my book(我的书)、your pen(你的钢笔)、her bag(她的书包)

(2)名词性物主代词:后头不加名词 ,尽头于“描写词性物主代词+名词”,不错单独使用,幸免重迭。

常见词汇 :mine(我的)、yours(你的/你们的)、his(他的)、hers(她的)、its(它的)、ours(咱们的)、theirs(他们的)

例句:This is my book. = This book is mine.(这是我的书 = 这本书是我的)

二、名词:可数 & 不可数 & 复数变化(高频考点)

名词是暗意东谈主、事物、场地的词,中小学重心检会“可数/不可数”的差别,以及可数名词的复数变化,这亦然易错点之一。

1. 名词分类

- 可数名词: 不错平直数出数目,有单数和复数两种模样。

例句:book(单数)→ books(复数)、student(单数)→ students(复数)

- 不可数名词: 不行平直数出数目,莫得复数模样,平凡搭配“量词”使用(如a glass of water)。

常见词汇 :water(水)、milk(牛奶)、rice(米饭)、bread(面包)、news(新闻)、money(钱)

2. 名词复数礼貌(必背)

大部分可数名词的复数变化有礼貌,记着以下5点,莽撞莽撞:

1. 一般情况:平直加 -s (最基础,占80%)

例句:book → books、pen → pens、desk → desks

2. 以 s, x, ch, sh 扫尾:加 -es

例句:bus → buses、box → boxes、watch → watches、brush → brushes

3. 以子音字母 + y 扫尾: 变 y 为 i ,再加 -es

例句:city → cities、family → families、study → studies

4. 以 f/fe 扫尾:变 f/fe 为 ves

例句:knife → knives、leaf → leaves、wife → wives

5. 不礼貌变化:疏淡记挂(重心记这几个)

例句:man → men、child → children、foot → feet、tooth → teeth、mouse → mice

三、冠词:a / an / the(工整但易错)

冠词是“小词”,但用法很要津,分为不定冠词(a/an)和定冠词(the),主要检会“什么时候用、什么时候毋庸”。

1. a / an(不定冠词)

中枢作用 :暗意“一个”,用于第一次提到某东谈主/某物,泛指某一类东谈主/物。

差别a和an的要津:看后头单词的发音(不是字母)!

- a + 子音音素开首的单词 (哪怕首字母是元音字母,发音是子音也用a)

例句:a book、a pen、a university(大学,发音/juː/,是子音)

- an + 元音音素开首的单词 (哪怕首字母是子音字母,发音是元音也用an)

例句:an apple、an egg、an hour(小时,发音/ˈaʊə/,是元音)

2. the(定冠词)

中枢作用 :暗意“专指”,指两边齐知谈的东谈主/物,或有特定修饰的东谈主/物,记着4个高频用法即可:

1. 专指两边齐知谈的东谈主/物: The book is on the desk.(这本书在桌子上,两边齐知谈是哪本书)

2. 惟一无二的事物前 :the sun(太阳)、the moon(月亮)、the earth(地球)

3. 序数词、描写词最高档前: the first(第一)、the best(最佳的)、the tallest(最高的)

4. 乐器前: play the piano(弹钢琴)、play the violin(拉小提琴)

注释: 球类、三餐前毋庸the,比如 play basketball(打篮球)、have breakfast(吃早餐)。

四、介词:期间、场地、方向(普通抒发必备)

介词是衔接单词、短语的“桥梁”,中小学最常考的便是6个:in / on / at / under / behind / next to,重心掌抓期间和场地用法。

1. 期间介词(高频考点)

记着“小规模用at,中等规模用on,大规模用in”,搭配例子记更牢:

- at + 具体技能、固定搭配

例句:at 7:00(在7点)、at noon(在中午)、at night(在晚上)、at weekends(在周末)

- on + 具体某天、星期、节日

例句:on Monday(在周一)、on June 1st(在6月1日)、on Children’s Day(在儿童节)

- in + 年、月、季节、早中晚

例句:in 2026(在2026年)、in summer(在夏天)、in the morning(在早上)、in March(在三月)

2. 场地方向介词(简便好记)

集中生计场景记,一看就懂:

- in:在……内部(in the room 在房间里)

- on:在……上头(on the desk 在桌子上)

- under:在……底下(under the chair 在椅子底下)

- behind:在……后头(behind the door 在门后头)

- next to:紧挨着(next to the window 紧挨着窗户)

- between:在……中间(between the two trees 在两棵树中间)

五、动词分类 & 基本模样(句子的“中枢骨架”)

动词是句子的“灵魂”,暗意算作或情景,中小学重心掌抓“动词分类”和“动词三态”,尤其是一般目下时的第三东谈主称单数变化。

1. 动词分类(3类中枢)

- 实义动词: 暗意具体算作,能颓唐作谓语(最常用)

例句:run(跑)、eat(吃)、study(学习)、read(读)

- 系动词: 暗意情景,不行颓唐作谓语,后头要跟表语

重心:be动词(am/is/are)、感官动词(look 看起来、sound 听起来、taste 尝起来)

例句:She is happy.(is是系动词,爱游戏体育apphappy是表语)、The cake tastes good.(tastes是系动词)

- 助动词: 不行颓唐作谓语,匡助实义动词组成时态、辩说句、疑问句

重心:do/does/did、will、have/has

例句:Do you like English?(do是助动词,匡助like组成疑问句)、He will go to school.(will是助动词,匡助go组成一般将来时)

2. 动词三态 & 第三东谈主称单数变化

动词三态:原形 → 往时式 → 往时分词(中小学重心先掌抓“原形”和“第三东谈主称单数”)

重心: 一般目下时中,主语是第三东谈主称单数时,动词要变三单模样 ,变化礼貌和名词复数有雷同之处,记着3点:

1. 一般情况:平直加 -s

例句:work → works、play → plays、read → reads

2. 以 s, x, ch, sh, o 扫尾:加 -es

例句:go → goes、watch → watches、do → does、wash → washes

3. 以子音字母 + y 扫尾:变 y 为 i,再加 -es

例句:study → studies、fly → flies、cry → cries

六、四大基本时态(中小学必考,重中之重)

时态是英语语法的“难点”,亦然磨砺的高频考点,中小学只需要掌抓4大基本时态,每个时态记着“含义、结构、记号词”,就能莽撞莽撞。

1. 一般目下时

含义: 暗意频繁、习气性的算作;客不雅事实、真义。

结构: 主语非三单 → 动词原形;主语三单 → 动词+s/es(集中第五部分的三单变化)

记号词: often(频繁)、usually(平凡)、always(老是)、every day(每天)、every week(每周)

例句: I get up at 7:00 every day.(我每天7点起床,习气性算作);The earth goes around the sun.(地球绕着太阳转,客不雅事实)

2. 目下进行时

含义: 暗意此时此刻正在进行的算作,或现阶段正在进行的算作。

结构: am/is/are + 动词ing模样(动词ing:一般加ing,去e加ing,双写尾字母加ing)

记号词: now(目下)、look(看)、listen(听)、at the moment(此刻)

例句: Look! They are playing football.(看!他们正在踢足球);I am reading a book now.(我目下正在看书)

3. 一般往时时

含义: 暗意往时某个期间发生的算作,或往时的习气性算作,算作依然甩手。

结构:动词往时式(礼貌变化+不礼貌变化)

礼貌变化: 1. 一般加 ed(play → played);2. 以e扫尾加 d(like → liked);3. 子音+y扫尾,变y为i加ed(study → studied)

不礼貌变化(重心记) :go→went、see→saw、do→did、eat→ate、write→wrote

记号词:yesterday(昨天)、last week(上周)、just now(刚才)、in 2025(在2025年,往时的年份)

例句:I went to the park yesterday.(我昨天去了公园);She ate an apple just now.(她刚才吃了一个苹果)

4. 一般将来时

含义 :暗意将要发生的算作,或绸缪、规画作念的事情。

结构: 两种模样,可互换(小学重心掌抓第一种)

1. will + 动词原形(全能模样,整个主语齐能用)

2. be going to + 动词原形(暗意绸缪、规画,be动词随主语变化)

记号词:tomorrow(未来)、next week(下周)、soon(很快)、in the future(在异日)

例句:I will go to Beijing tomorrow.(我未来要去北京);She is going to study hard.(她规画奋发学习)

七、There be 句型(“有”的抒发,简便易记)

There be 句型特意暗意“某地有某物”,和汉文的“有”用法不同,重心掌抓“主谓一致”和“就近原则”。

中枢结构:

- 单数/不可数名词: There is + 名词

例句:There is a book on the desk.(桌子上有一册书);There is some water in the bottle.(瓶子里有一些水)

- 复数名词: There are + 名词

例句:There are two pens in the bag.(书包里有两支钢笔);There are many students in the classroom.(教室里有许多学生)

重心:就近原则: be动词的单复数,看离它最近的名词(非论后头还有若干名词)。

例句:There is a pen and two books on the desk.(桌子上有一支钢笔和两本书,离be动词最近的是a pen,是以用is)

There are two books and a pen on the desk.(桌子上有两本书和一支钢笔,离be动词最近的是two books,是以用are)

八、句子结构与五大基本句型(语法终极考点)

掌抓了前边的常识点,终末一步便是学会“造句”,而造句的中枢便是掌抓句子结构和五大基本句型,非论是简便句照旧复杂句,齐离不开这五大句型。

1. 句子身分(基础必备)

先搞懂句子的“组成部分”,才智写出正确的句子:

- 主语(S) :算作的发出者,平凡是名词、代词(如I、he、the book)

- 谓语(V): 算作或情景,平凡是动词(如run、is、eat)

- 宾语(O): 算作的承受者,平凡是名词、代词(如English、me、a book)

- 表语(P): 跟在系动词后头,阐述主语的情景、特征(如happy、tall、a student)

- 定语: 修饰名词,尽头于“……的”(如my book中的my,red pen中的red)

- 状语: 修饰动词、描写词,阐述期间、场地、风光(如in the morning、very fast)

2. 英语五大基本句型(必背,造句全能)

整个英语简便句,齐逃不出这5种句型,集中例句记,平直套用就能造句:

1.主谓(S+V) :主语+不足物动词(动词后头不接宾语)

例句:He runs.(他跑步);She smiles.(她含笑);The sun rises.(太阳升空)

2. 主谓宾(S+V+O) :主语+及物动词+宾语(最常用)

例句:I love English.(我爱英语);He reads a book.(他读一册书);They play football.(他们踢足球)

3. 主系表(S+V+P) :主语+系动词+表语

例句:She is happy.(她很振作);He is a student.(他是别称学生);The flower is red.(这朵花是红色的)

4. 主谓双宾(S+V+IO+DO) :主语+及物动词+蜿蜒宾语+平直宾语(蜿蜒宾语是东谈主,平直宾语是物)

例句:He gave me a book.(他给了我一册书,me是蜿蜒宾语,a book是平直宾语);She bought her mother a gift.(她给她姆妈买了一份礼物)

5. 主谓宾补(S+V+O+C) :主语+及物动词+宾语+宾语补足语(补充阐述宾语的情景)

例句:We make the room clean.(咱们把房间打扫干净,clean补充阐述room的情景);He keeps the window open.(他让窗户开着)

3. 句子种类(了解即可,磨砺常考疑问句)

- 答复句: 暗意细则或辩说,口吻安然(如I love English. / I don’t like coffee.)

- 疑问句: 暗意发问,分为一般疑问句(Do you like it?)和疏淡疑问句(What do you like?)

- 祈使句: 暗意呐喊、苦求,不祥主语(如Open the door. 开门;Please sit down. 请坐下)

- 惊羡句: 暗意历害的神思,用What或How指点(如What a beautiful flower! 何等漂亮的花啊!How happy I am! 我何等振作啊!)
