7、can.B.No,I can do it.C.Yes.Id like some oranges.人称代词和物主代词要点归纳:人称代词I like you.我喜欢你。You like me.你喜欢我。He likes her.他喜欢她。She likes him.她喜欢他。We like you.我们喜欢你们。You like us.你们喜欢我们。They like us.他们喜欢我们。We like them.我们喜欢它们。上面这些简单的句子里,like 前面的人称代词都是主格,你可以把like 换成别的动词,比如 play with(和,玩)、look at(看着)等等,读着玩玩儿,你认为哪
8、个动词好玩就换成哪个。形容词性物主代词有:my 我的、your 你的、his 他的、her 她的、its 它的、our我们的、your 你们的、their 他们的。之所以叫它们形容词是因为他们必须放在名词前面。物主则表示它们是物的主人。如:我们的老师 our teacher、我的汽车 my car、你的裤子 your trousers、他的风筝 his kite、她的椅子 her chair、它的腿 its legs、你们的学校 your school、她们的聚会 their party。名词性物主代词有 mine,yours,his,hers,its,ours,yours,theirs 依次
9、表示我的、你的、他的、她的、它的、我们的、你们的、他(她、它)们的。注意除了mine每个单词后面都有一个“s”。因为他们本身是名词性,所以后面不能再跟名词,否则就犯了重复的错误。比如我们可以说 my book,但不能说 mine book;her dress而不是 hers dress。This is my book.The book is mine.这是我的书。这书是我的。That is your desk.That s yours.那是你的课桌。那是你的。This is his cup.Its his.这是他的杯子。是他的。That is her skirt.The skirt is he
10、rs.那是她的短裙。那短裙是她的。Thats its banana.The banana is its.那是它的香蕉。那香蕉是它的。This is our classroom.Its ours.这是我们的教室。是我们的。This is their basketball.Its theirs.这是他们的篮球。是他们的。-主 格宾 格形容词性物主代词名词性物主代词-一单I 我me我my 我的mine 我的,-一复we 我们us 我们our 我们的ours我们的,-二单you 你you 你your 你的yours你的,-二复you 你们you 你们your 你们的yours你们的,-三单he他him

13、 our your their)1.形容词性物主代词一般位于名词前,用作定语,限定该名词的意义。(1)_ book is over there.(2)I ate all _ sandwiches yesterday.(3)Tell Tom not to forget _ book.四 名 词性 物 主 代词(mine yours his hers its ours yourrs theirs)1.名词性物主代词在句中独立使用,即不后接名词,其句法作用相当于一个名词,即“形容词性物主代词+名词”。(1)My bag is bigger than _.=My bag is bigger than
14、_ _.(2)_ is a great country.我们的国家是一个伟大的国家。(用作主语,一般用于正式文体)(3)I forgot to bring my dictionary.Could I use _?我忘了带词典,我可以用一下你的吗?(用作动词的宾语)(4)He wasnt in my room.He might be in _.他(刚才)不在我的房间。他可能在自己的房间。(用作介词的宾语)(5)Whose book is this?It s _.这是谁的书?是她的。(用作表语)(6)Jack is a friend of _.杰克是我的一个朋友。(用于双重所有格)2.名词性物主代
