英语(三年级上册)重要知识点归纳总结

.26个英文字母的正确认读与正确规范占格书写。

字母GgJj 的发音、Ii Rr的发音易混淆。

BbDd Pp Qq Ii Ll 的外形容易混淆,尤其就是它们的小写。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。

2.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

Ahe B He C She

因为Mr Li就是男的,所以,下文的代词应该用he(),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

3. 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 fatherHe is cool

Sally is my sister She is lovely

3 You are a girl You are beautiful

Kitty and Alice are good friends

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 arent

7 Is he Joe? Yes , he is

8 Is this your pen ? Yes , it is

.人称代词(主格)的准确使用。

1. 第一人称 I ()

例如:I am tall and thin I am nine

2. 第二人称单复数一样,都就是you ( ,您们 )

例如:You are Kitty ( 您就是Kitty)

You are my friends ( 您们就是我的朋友。)

3. 第三人称单数he (),she ()it()

例如:This is my fatherHe 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 (她们、她们、它们)

How much are they? ---- They are ten yuan

These are my books They are new ( 它们就是新的。)

备注:“人称代词的主格”在句中作主语,因此,称之为“主格”

.人称代词(宾格)的使用

1、第一人称 me ( )

This is me Look at me

This is a small pear Its for me

My father and mother love me

2. 第二人称you ( ,您们)(见课本P40)

Here are two pears for you

This is a big pear Its for you

3 第三人称单数it(),复数them(她们、她们、它们)

Look at my rabbit Its 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”。

.形容词性的物主代词 。目前只学习了三个:my ( 我的 )

your ( 您的,您们的), 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

3This 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 Its funny

7.名词的考查

了解:英语中名词分为可数名词不可数名词

可数名词有单数形式( 即原形)复数形式

可数名词复数形式的变化分为:规则变化与不规则变化。

规则变化方法:(先记住以下三种方法,以后随学随补充)

在词尾直接加-s 。例: apple- apples ,boy- boys ,

s ,x , ch ,sh 结尾的单词要加-es 。例: peach - peaches

“辅音字母 + y 结尾的词,要先把y 变为i , 再加-es

:family - families

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 - mice

snowman -- snowmen

单复同形的词:sheep, fish

8.冠词的考查

英语中的冠词有:不定冠词 a , an 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, :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,指说话人与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

9.代词it 的用法

it的意思就是“它” ,但就是 it在不同的语境中,其含义就是不一样的。

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。

I have a dog It is cool I love it ( 代指上文提到的dog)

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)

It is winter in Taiyuan 太原现在就是冬季。( 指季节)

In spring ,it is warm 在春天,天气温暖。(指天气)

.易混词 its its

Its = it is ( 它就是、、、)

Its(它的),就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 Its 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”,其她数词后面必须用“可数名词的复数”

-- How many boys ?-- Three boys

-- How many girls ? -- One girl

十二.句型

()陈述句 ( 有肯定句与否定句之分 )

肯定陈述句:This is Kitty Shes thin Im Peter, Im short

My hair is long My ears are small

11-- How old is he / she? /她多大了?

-- Hes / Shes ten years old /10岁。

()祈使句

祈使句就是表示“命令、要求、请求”等的句子。

肯定形式:动词原形开头,常与please连用,please可以在句首,也可以在句末。请瞧课本中的祈使句 (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

Lets 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

十四.记住所学的“缩写词”

Im = I am isnt = is not

在句首时大写首字母 不在句首时不必大写首字母

Youre = You are youre =you are

Hes = He is hes = he is

Shes = She is shes = she is

Theyre = They are theyre = they are

Its = It is its = 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,这也就是涉及到人称代词he she 的正确选择。

例如下列句子:

This is Ben He is my brother( Ben 就是男名,所以下文用He来代替)

This is Sally She is my sister( Sally就是女名,所以下文用 She来代替)

This is my brother He is cool( brother 这一称谓就是男的,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,都就是常常设为空格,来让学生们选择或填写的。
