⼩学英语(三年级上册)重要知识点归纳总结
英语(三年级上册)重要知识点归纳总结
⼀.26个英⽂字母的正确认读和正确规范占格书写。

字母Gg和Jj 的发⾳、Ii 和Rr的发⾳易混淆。

Bb和Dd 、Pp 和Qq、Ii 和Ll 的外形容易混淆,尤其是它们的⼩写。

Cc 的发⾳容易读错。

能准确认读并书写五个元⾳字母:Aa , Ee , Ii , Oo ,Uu的⼤⼩写。

⼆.Miss, Mr , Mrs 这三个词的准确认读及听辨。

Mr(先⽣),指男性Miss (⼩姐)、Mrs (夫⼈、太太)指⼥性
这要涉及到“⼈称代词”的选择及图⽚的选择。

例如:选择题
( ) This is Mr Li. ______ is tall and thin.
A.he
B. He
C. She
因为Mr Li是男的,所以,下⽂的代词应该⽤he(他),⼜因为这个代词在句⾸,所以要⼤写⾸字母。

因此,这道题应该选择B.
三.be 动词在⼀般现在时中的三种形式am, is ,are
1. I am Peter .I am a boy.
2. He/ She is my friend. He /She is tall and thin. My mother is beautiful.
This is my father.He is cool.
Sally is my sister. She is lovely.
3. You are a girl .You are beautiful .
Kitty and Alice are good friends. I⽤am, you⽤are
is连着he/she/it
不可数⽤is
(可数)单数is, 复数are 变疑问,be提前
肯定回答不缩写
否定be后加not
4.My eyes are big. My hair is long.
5.Are you Kitty ? Yes, I am.
6. Are these your rulers ? Yes , they are ./ No ,they aren’t.
7. Is he Joe? Yes , he is.
8. Is this your pen ? Yes , it is.
四.⼈称代词(主格)的准确使⽤。

1.第⼀⼈称I (我)
例如:I am tall and thin. I am nine.
2.第⼆⼈称单复数⼀样,都是you ( 你,你们)
例如:You are Kitty. ( 你是Kitty。


You are my friend s. ( 你们是我的朋友。


3.第三⼈称单数he (他),she (她)it(它)
例如:This is my father.He is fat.
This is my sister. She is tall and thin.
Look at the cat. It is fat.
4.第三⼈称复数they (他们、她们、它们)
How much are they? ---- They are ten yuan .
These are my book s. They are new. ( 它们是新的。


备注:“⼈称代词的主格”在句中作主语,因此,称之为“主格”五.⼈称代词(宾格)的使⽤
1.第⼀⼈称me ( 我)
This is me. Look at me.
This is a small pear. It’s for me .
My father and mother love me.
2.第⼆⼈称you ( 你,你们)(见课本P40)
Here are two pears for you .
This is a big pear. It’s for you .
3. 第三⼈称单数it(它),复数them(他们、她们、它们)
Look at my rabbit . It’s beautiful. I love it.
--Count the chicks,please. How many chicks?--Nine chicks.
-- No, count them again.
备注:“⼈称代词的宾格”⼀般出现在介词、动词之后,在句中作宾语,所以,称之为“宾格”。

六.形容词性的物主代词。

⽬前只学习了三个:“my ”( 我的)“your ”( 你的,你们的), “its ”(它的)形容词性的物主代词后⾯须有⼀个名词。

1. This is my friend.
2. Mary is my sister Tina.
3.This is your book.
4. Are these your rulers?
5. Look at the cat. Its eyes are big. Its tail is long.
6. Here is a snowman. Look at its nose. It’s funny.
七.名词的考查
了解:英语中名词分为可数名词和不可数名词
可数名词有单数形式(即原形)和复数形式。

可数名词复数形式的变化分为:规则变化和不规则变化。

规则变化⽅法:(先记住以下三种⽅法,以后随学随补充)
①在词尾直接加-s 。

例:apple- apple s ,boy- boy s ,
②以s ,x , ch ,sh 结尾的单词要加-es 。

例:peach - peach es
③以“辅⾳字母+ y”结尾的词,要先把y 变为i , 再加-es。

例:famil y - famil i es
不规则变化(改变单词的某些字母来构成其复数形式,必须牢记)
⽬前学过的:mouse - m ice
snowm a n -- snowm e n
单复同形的词:sheep,fish
⼋.冠词的考查
英语中的冠词有:不定冠词 a , an 和定冠词the .
a, an 与可数名词的单数连⽤,表⽰“⼀个”或“⼀类”事物,
a⽤在“辅⾳⾳素开头的单词”前⾯,如:This is a book.
an ⽤在“元⾳⾳素开头的单词”前⾯。

如:Here is an apple for you.
the 表⽰特指,指说话⼈和听话⼈都知道的事物。

有关它的⽤法以后随学随讲。

Close the door , please.
Look at the blackboard ,please. Look at the snow.
九.代词it 的⽤法
it的意思是“它”,但是it在不同的语境中,其含义是不⼀样的。

it可以指代“上⽂提到的单数名词或不可数名词”,也可以指“时间、距离、天⽓”等。

① I have a dog .It is cool .I love it .( 代指上⽂提到的dog)
② Here is some milk. Drink it ,please.这⾥有⽜奶,请喝吧。

(代指上⽂提到的“⽜奶milk”)
③It is winter in Taiyuan. 太原现在是冬季。

(指季节)
④ In spring ,it is warm. 在春天,天⽓温暖。

(指天⽓)
⼗.易混词it’s 和its
It’s = it is (它是...)
Its(它的),是形容词性物主代词,它后⾯必须有名词出现
I have a rabbit. Its eyes are big .Its hair is white. It’s beautiful.
⼗⼀.数词的考查
本册书涉及到⼗个英语基数词(one ,two ,three , four , five ,six , seven ,eight ,nine ,ten),数词主要⽤于回答“How many ...? ”提出的问题。

数词one 后⾯必须⽤“可数名词的单数”,其他数词后⾯必须⽤“可数名词的复数”
-- How many boy s ?-- Three boy s.
-- How many girl s ? -- One girl.
⼗⼆.句型
(⼀)陈述句(有肯定句和否定句之分)
肯定陈述句:This is Kitty. She’s thin . I’m Peter, I’m short.

(“How many ”后⾯必须接可数名词的复数形式)
7. -- What is it ? 它是什么?
-- It is a rabbit. 它是兔⼦。

拓展:8:-- There are four season sin a year . ⼀年有四季。

11.-- How old is he / she? 他/她多⼤了?
-- He’s / She’s ten years old. 他/她10岁。

(四)祈使句
祈使句是表⽰“命令、要求、请求”等的句⼦。

肯定形式:动词原形开头,常和please连⽤,please可以在句⾸,也可以在句末。

请看课本中的祈使句(Units 9--- 12 的⽂本中都有)
Close the door ,please. = Please close the door.
Open the window,please.= Please open the window.
Look at the blackboard.
Please clean the blackboard.
Count the chicks.
Let’s make a snowman.
否定祈使句以后会学习的,到时候再讲。

⼗三. ⼝语交际
A: You’re beautiful. B: Thank you.A: Hello, Peter. B: Hello, Kitty.
A: I’m sorry .
B: That’s OK .
A: Good morning. B: Good morning
A: Your room is nice. B: Thank you. A: Let’s make a snowman . B: OK.
A: Four apples ,please. A: Open the door, please.
⼗四.记住所学的“缩写词” I ’m = I am isn ’t = is not
在句⾸时⼤写⾸字母不在句⾸时不必⼤写⾸字母
You ’re = You are you ’re =you are
He ’s = He is he ’s = he is
She ’s = She is she ’s = she is
They ’re = They are they ’re = they are
It ’s = It is it ’s = it is
注意:句⾸字母要⼤写、名字的⾸字母要⼤写、专有名词的⾸字母要⼤写。

要清楚课本上所有英语名字的性别、家庭成员中每个称谓的性别,这也是涉及到⼈称代词he 和she 的正确选择。

例如下列句⼦:
This is Ben . He is my brother.( Ben 是男名,所以下⽂⽤He 来代替)
This is Sally. She is my sister.( Sally 是⼥名,所以下⽂⽤ She 来代替)
This is my brother. He is cool.( brother 这⼀称谓是男的,所以下⽂⽤He 来代替)因为在句⾸,所以都⼤写了⾸字母。

备注:红⾊字体的词,都是常常设为空格,来让学⽣们选择或填写的。

A: How are you ?
B: I ’m fine .Thank you. A: You ’re late,Kitty . B: I ’m sorry . A: Here are two pears for you . B: Thank you. A: Here you are. B: Thank you.
