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 and thi n.B. HeC. 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 ,are2. He / She is my frie nd. He /She is tall a nd thn.连着 he/she/it1.1 am Peter 」 ama boy.JI 用 am, you 用 areMy mother is beautiful. 不可数用isThis is my is cool.(可数)单数is,复数are Sally is my sister. She is lovely.3.

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 frie nd 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 is fat.This is my sister. She is tall and thi n.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 yua n .These are my book s. They are n ew.(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)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 myfriend.2. Mary is mysister Tina.is your book.4. Are these your rulers5. 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 es③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 icesnowm an -- snowm en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,女口: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 atthe 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。
①I have a dog . It is cool」love it .(代指上文提到的dog)②Here 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)④In spring , it is warm. 在春天,天气温暖。
(指天气)十.易混词it ' s和itsIts (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。
