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、li和Rr的发音易混淆。

Bb和Dd、Pp和Qq、li和LI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 a nd thi n.

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 ------------------------------------- --------------------------

f

1. I am Peter」am a boy. I 用am, you 用are

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 frie nds. 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

7. Is he Joe? Yes , he is .

8. Is this your pen ? Yes , it is.

.B I I F .

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 friends.(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.

4.第三人称复数they (他们、她们、它们)

How much are they?——They are ten yua n .

These are my books. 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 '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 '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 'beautiful. I love it.

--Co unt the chicks,please. How many chicks?--Ni ne chicks.

--No, count them aga in.

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 sno wma n. Look at its no se. It '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- apples ,boy- boys ,

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