John has two new friends.(注意谓语动词has,数量two,可数名词变复数)▲▲▲主语表示单数时用has,主语表示复数时用have,如以下常用搭配:(1)He has an apple.(2)She has an apple.(3)It has a long nose.(he/she/it是第三人称单数)(4)The cat has small ears.(the cat 是单数)(5)The cats have small ears.(the cats 是复数)(6)The students have some books.(the students是复数)(7)I have a book.(I是第一人称,谓语动词用原形)(8)You have a book,too.(you是第二人称,谓语动词用原形)(9)The man has a blue bag.(10)That woman has a good friend.(that woman 是单数)(11)Mike has an apple.(Mike是单个人名,作单数)(12)Miss Li has a red bag.(Miss Li 是称呼,是第三人称单数)(13)They have two new students.(they他们,是复数)(14)We have a new teacher.(we意思是我们,是复数,谓语动词用原形。
)总结:主语是第三人称单数时,谓语动词要用第三人称形式。
have 是动词原形,has就是have的第三人称单数形式。
问:什么是第三人称单数?①人称代词he/she/it是第三人称单数。
He is a student.②单个人名(如Mike/Amy等)、地名(如Beijing等)、称呼(如Uncle Wang/Miss Li等)作主语,是第三人称单数。
Mike is a student.Beijing is in China.Uncle Li is a teacher.③单数可数名词或“this/that/the+单数可数名词”作主语时,是第三人称单数。
如:(this man/that woman/this boy/that girl/the man/the student/the book/the cat)This man is my father.That boy is my friend.The book is red.The cat is so fat.④数字或字母作主语时,看作第三人称单数。
“I”is a letter(字母)。
⑤不可数名词作主语时为第三人称单数。
The bread is so small.(the bread、the cake 是不可数名词)7.对新朋友表示欢迎:Welcome!Unit21.A:Who’s this(that)man(boy)?B:He’s my father(brother).2.A:Who’s this(that)woman(girl)?B:She’s my mother(sister).询问某人是谁?回答的主语要与上一个问句中主语保持一致。
▲▲A:What’s he?(特殊疑问词是what,询问某个人的职业)(易错题)B:He is a teacher.3.A:当你要鼓励你的朋友一起和你玩时,英语怎么说:B:Come on!4.A:Let’s watch TV.B:OK!/Great!Let’s =Let us(let后跟人称代词宾格)如:Let me/him/her clean the desk.(clean①形容词,干净的;②动词,清洁,在这里就是动词原形)5.A:Is she your sister?B:No,she isn’t./No,she’s my mum./Yes,she is.6.A:Are you a teacher?B:Yes,I am./No,I’m a nurse./No,I’m not.7.A:怎么用英语介绍自己的家庭:B:This is my family.向爸爸介绍你的朋友:Dad,this is my (good )friend.8.初次见面打招呼:Nice to meet you.回答:Nice to meet you,too. How do you do?回答:How do you do?9.A:怎么用英语表达“多大的一条鱼啊!”B:What a bigfish!这是一个感叹句!(结构:What+冠词+形容词+可数名词单数+主语+谓语!)What引导的感叹句经常把主语和谓语省略。
She is a beautiful girl.——(改成感叹句)What a beautiful girl she is!——What a beautiful girl!10.H ow也可引导感叹句(结构:How+形容词+/副词+冠词——可数名词单数+主语+谓语!)How引导的感叹句常只How+形容词/副词,其余省略。
She is a beautiful girl.——(改成感叹句)How beautiful a girl she is!——How beautiful!真漂亮啊!Unit31.A:Look at the elephant.B:Wow,it’s so big!It has big ears , big body and a long nose.2.I have a monkey. ——Cool./Wow/Super.3.How many animals do you know?I know all the animals.4.Amy has a rabbit.It has long ears.Unit41.Mum,where is my car?It’s +介词短语(on your desk/in the toy box/under the chair.)询问别人某物在哪里回答It’s…2.询问别人某物在哪里?对方可能不清楚,会以疑问语气回答。
如: Where is my pen?——Is it in your desk?3.Excuse me,Amy.Can I use your pencil?打扰了,Amy.我能用一下你的铅笔吗?No,problem.没问题。
Look out!=Watch out!小心!4.Let’s play a game.让我们玩游戏吧。
——OK.Let’s play hide and seek.让我们玩捉迷藏吧。
——OK/Great!5.Are you ready?Yes!你准备好了吗?好的!6.Where are you?I can’t find you.你在哪里?我找不到你。
I’m behind you.(behind在…后面,介词)(can情态动词,其后动词要用动词的原形;否定在can后加not=can’t;疑问句直接把can提前;情态动词不能单独使用)类似的情态动词:must/will/shall/may+动词原形(没有人称变化)不同情态动词表达的不同程度的猜测:①must:肯定,一定,必须怎么样,没有过去时态。
加not,变成must not=mustn’t,表示禁止。
如:We must finish(完成)our homework this afternoon.今天下午我们必须完成家庭作业。
We mustn’t come here.②can能,会,可以,表示能力,允许有过去时could是它的过去时态。
否定在后加not③will表示愿意;表示将来;过去式wouldI will play football this afternoon。
(这个时间还没发生)④may表示可以,可能;过去式might7.Happy Children’s Day!Thank you!儿童节快乐!谢谢!Happy Women’s Day!Unit 51.Do you like pears?Yes,I do./No,I don’t.(询问别人喜欢某种东西吗?)Does Mike like bananas?Yes,he does./No,he doesn’t.●Like的用法:(1)作动词:like+名词/代词喜欢某人或某物如:I like apples。
(2)作动词:like+to do(动词原形)某一次喜欢做某事如:I like to fish(动词:钓鱼)/swim/run/sing this afternoon. (3)作动词:I like+doing(动名词形式)长期喜欢、爱好做某事如:I like fishing./swimming/running/singing.(4)would like to do =want to do 想做某事(5)Would you like +名词/to do sth?你想要什么吗?(6)作介词:be like/look like +名词/代词作宾语:像…,跟…一样。
如:The little girl looks like her father.●助动词do和does的用法:Do的否定形式:do not(缩写don’t)Does的否定形式:does not(缩写doesn’t)主谓宾句式的否定与疑问要借助助动词来完成。
I/you/we/they/the students +don’t like apples.I/you/we/they/the students like apples.(主语是第一、二人称或第二、三人称复数,谓语动词用原形时,句子的否定在谓语动词前直接加don’t)He/She/It /The student/This boy /The cat likes apples.He/She/It /The student/This boy /The cat doesn’t like apples. (主语是单数,谓语动词是第三人称单数形式,句子否定要把在谓语动词前加doesn’t,并把动词变成动词原形)2.Let’s buy some pears.3.Sorry,I don’t like bananas.4.A:Can I have an apple,please?B:Sure.Here you are.5.I’m hungry./I’m full.我饿了。
