高考英语语法专题复习--代词

高考英语语法专题复习 三、代词 知识要点： 代词是代替名词、名词短语或句子的词。代词可分为人称代词、物主代词、指示代词、反身代词、不定代词、疑问代词、相互代词、连接代词、关系代词等九类。 一、人称代词 人称代词在句中可以用作主语(用主格，如I, you, he, she, it, we, they, 等)和宾语(用宾格，如me, you, him, her, it, us, them等)： 人称代词的用法: 注：(1)在电话中或It is/was...that/who...强调句型中被强调部分做主语时，用主格： ---Is that Mr. Li? ---Yes. This is he. It’s I who did it. 这是我干的。 (2)单独使用的人称代词通常用宾格： “I’m tired.” “Me too.” “我累了。”“我也累了。”“Who wants this?” “Me.” “谁要这个？”“我要。” (3)有时用主格或宾格会导致意思的变化： I like you better than he. 我比他更喜欢你。为I like you better than he likes you. I like you better than him. 我喜欢你胜过喜欢他。为I like you better than I like him. (4)人称代词的排列顺序：单数人称代词通常按“二三一”排列，即you, he and I； 复数人称代词通常按“一二三”排列，即 we, you and they：You, he and I are of the same age. 你，他和我都是同一年龄。 We , you and they are all good citizens. 我们，你们和他们都是好公民。 但若用于承担责任或错误等场合，则可把第一人称 I 置于其他人称代词之前： Tom and I hope to go there. 汤姆和我想去那儿。I and Tom are to blame. 我和汤姆该受批评。 但是，you and I 是固定结构，语序通常不宜颠倒。 (5)人称代词后跟名词同位语。有些人称代词后有时可跟同位语： These small desks are for us students. 这些小课桌是给我们学生的。 We girls often go to the movies together. 我们女孩子常一起去看电影。 He asked you boys to be quiet. 他要你们男孩子安静些。 二、物主代词 物主代词分形容词性物主代词(my, your, his, her, its, our, your, their)和名词性物主代词(mine, yours, his, hers, its, ours, yours, theirs)。形容词性物主代词相当于形容词，置于名词前，作定语；名词性物主代词相当于“形容词性物主代词+名词”，在句中作主语、宾语、表语、连用of作定语：His son is taller than hers. 他的儿子比她的儿子高。 Ours is a great country. 我们的国家是一个伟大的国家 Her son is a friend of ours. 她的儿子是我们的朋友。 This is your pen. Mine is in the box. 这是你的铅笔，我的在铅笔盒里。 注：(1) a friend of mine (ours, yours, hers, his, theirs)结构 (2) 物主代词与own 连用。表强调。也可用of one’s own置于名词后作定语： Mind your own business. 别管闲事。

名词性物主代词

名词性物主代词 英语中的物主代词可分为形容词性物主代词和名词性物主代词。 形容词性物主代词： 单数形式：my（我的），your（你的），his /her/ its（他的、她的、它的）。 复数形式：our（我们的），your（你们的），their（他们的）。 名词性物主代词： 单数形式：mine（我的xx），yours（你的xx），his /hers /its（他的xx、她的xx、它的xx）。 复数形式：ours（我们的xx），yours（你们的xx），theirs（他们的xx）。 代词表格： 名词性物主代词的用法： 1. 形容词性物主代词起形容词的作用，用在名词前。（黑体为形容词性物主代词） e.g：1. This is my book. 这是我的书。 2. 名词性物主代词起名词的作用。（黑体为名词性物主代词） e.g：This book is mine. 这本书是我的。 3. 注意：在使用名词性物主代词时，必须有特定的语言环境，也就是要省略的名词大家已经知道，已经提起过。 e.g： It's hers. 是她的。 （单独使用大家不知是怎么回事，不可以这样用。） There is a book. It's hers. 这有本书。是她的（书）。 （这里的hers=her book） 只有上文提及了某个名词，才会知道名词性物主代词指代的事物。

4. 为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词+名词”的形式。 e.g：My bag is yellow, her bag is red, his bag is blue and your bag is pink. 为避免重复使用bag，可写成My bag（形容词性） is yellow, hers（名词性=her bag）is red, his（名词性=his bag） is blue and yours（名词性=your bag） is pink. 5. 名词性物主代词可以用在介词of的后面，相当于“of+名词所有格”。 e.g Jack is a friend of mine. Jack 是我的一个朋友。 练习： 1.Look at the clock. _____(it)face is round. 2.Alice is ______ new classmate. She is sitting beside_____. (I) 3.Here is ______ present. Here _____ are. (you) 4.Let _____ (he) help you with your English. 5.The books on the shelf are ______(she). 6.This is not _____ bag, _____ is yellow. (I) 7.The boy in front of _____ is _____ brother.

冠词名词。代词形容词副词、介词的知识点

冠词 不定冠词的用法及语法说明 1. 用a 还是用an： 一般说来，在辅音或半元音开头的词前用a, 而在元音开头的词前用an。 注意： 有些以元音字母开头的单词，由于第一个音不是元音而是辅音，其前仍用a而不用an： a one-eyed man 一个独眼人 a European country 一个欧洲国家 2. 单数可数名词若泛指，其前需加a ，an, 不要从汉语习惯出发，漏掉此不定冠词： He is a famous film star. 他是着名影星。 3. 专有名词转化为普通名词，其前可用a (an)，表示某某人或某某人的一部作品、艺术品等： a Mr Smith 一位名叫史密斯先生的人 4. 物质名词转化为普通名词，其前可以使用a (an)，有时表示相应产品或种类，有时表示数量关系： a good wine 一种好酒 5. 在序数词之前使用a (an)，可以表示数量或序数的增加： Soon I saw a second plane. 不久我又看到了一架飞机。 6. 与形容词的最高级连用，表示“非常”、“很”等： This is a almost interesting story. 这是一个非常有趣的故事。 7. 用于修饰名词的定语前，表示某种状态。此时的不定冠词含有类似a kind of 的意思：climate 气候→a mild climate 温和的气候 have breakfast 吃早餐→have a quick breakfast吃快餐 8. 不定冠词a (an) 与数词one 都可表示“一”，但是两者有差别： 不定冠词a (an) 表示“类别”概念，而数词one 表示“数量”概念 9. 两个单数可数名词连用表示一个整体时，只用一个冠词： He is a teacher and poet. 他既是老师又是诗人。 10. 与副词quite / rather 连用时，a (an) 一般要后置，但若其后的名词前有形容词修饰，则a (an) 放在quite rather 之前或之后均可以： He is rather a fool. 他是个大傻瓜。 It is quite a good book. 那是本很好的书。 It is a quite good book. 那是本很好的书。 11. 当too, so, as, how 等词之后接有“形容词＋单数可数名词”时，不定冠词a (an) 应放在形容词和单数可数名词之间 It is too difficult a book for us beginners. She is as good a cook as her mother. 12. 不定冠词可用来表示“类属”，这是其基本用法，它表明的是某一类属中的每一个人和东西都能说明该类属的整体情况。此时也可用定冠词或名词复数形式来表示。 正：A horse is a useful animal. 正：Horses are useful animals.

初中英语名词性物主代词

名词性物主代词 1.名词性物主代词可以单独使用，在句子中可以作主语、表语、宾语使用。 May I use your pen? Yours works better. I love my motherland as much as you love yours. 2.名词性物主代词 =相应的形容词性物主代词＋名词 (为避免重复使用) 如：Your bedroom is big. Mine (=My bedroom) is big, too. 你的卧室大。我的卧室也大。 如：My bag is yellow, her bag is red, his bag is blue and your bag is pink. 为避免重复使用bag ，可写成My bag is yellow, hers is red, his is blue and yours is pink. ※注意：A) 名词性物主代词后不能跟名词，或代词one 。它总是单独出现在句中。如：The umbrella is mine. He likes my pen. He doesn’t like hers. B) 名词性的物主代词在用法上相当于省略了中心名词的 --'s 属格结构. 如：Jack's cap 意为 The cap is Jack's. His cap 意为 The cap is his. C) 可以说 a friend of mine (ours, yours, hers, his, theirs) ，=one of my friends；但是不能说 a friend of me (us, you, her, him, them)。
