英语人称代词、物主代词、名词所有格—、人称代词分为第一人称、第二人称、第三人称；有主格和宾格两种形式。

1•人称代词主格：作主语，表示谁怎么样了、干什么了。

例：（1）I am a teacher. （2）You are a student.（3）He is a student, too. （4）We/You/They are students.2•人称代词宾格：作宾语，表示动作行为的对象。

一般放在动词和介词之后。

例：（1）Give it to me. （2）Let' s go （let ' s =let us）二、物主代词可分为形容词性物主代词和名词性物主代词。

1. 形容词性物主代词：起形容词的作用，用在名词前，用作定语，限定该名词的意义。

例：（1）This is my book.这是我的书。

2）We love our motherland.我们热爱我们的祖国。

2. 名词性物主代词起名词的作用，后面无名词。

例: （1）Look at the two pencils. The red one is yours and the blue one is mine.看那两支铅笔，红的是你的，蓝的是我的。

（2）He likes my pen. He doesn ” t like he他喜欢我的钢笔，不喜欢她的。

3）Lucy' s hair is longer than Lily's. 露西的头发比莉莉的更长。

3. 注意：在使用名词性物主代词时，必须有特定的语言环境，即要省略的名词大家已经知道，前文已经提起过。

例：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 'hers.那有本书。

是她的。

（先提及，大家才明白）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. 名词性物主代词=形容词性物主代词+名词名词性物主代词在一定情况下可以用“形容词性物主代词 +名词”来转换；有时为避免重 复使用名词，也可用“名词性物主代词”来代替“形容词性物主代词 +名词”的形式。

例：（1）This is my ruler.=This ruler is mine.Those are his clothes.=Those clothes are his.（2） 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形容词性物主代词和名词性物主代词的用法口诀 ：形容词性物主代词能力差，自己不能 来当家，后面需把名词加。

名词性物主代词能力强，自己独来又独往。

6. 形容词性物主代词变为名词性物主代词遵循“一二四”原则：一改 my 为 mine ； 二 his its 保持不变；四在 your, her, their, our 后加上 s 。

三、名词所有格：表示所有关系，通常在人或有生命的名词后加上 '或’来构成，表示“的”；既可以当形容词性物主代词用，也可以当名词性物主代词用。

名词所有格构成形式规律：（1） 单数名词以及不以-s 结尾的复数名词加 '。

例：Tom ' book 汤姆的书 Children ' Day 儿童节（2） 以结尾的复数名词只加 ' 例：students ' schoolbags 学生们的书包 （3） 表示两个人共同拥有某物时，只需将在后面的名词变为所有格形式。

This is Lucy ' and Linda ' mother.这是露西和琳达的妈妈。

（4）表示两个人各自拥有某物时，需将两个名词变为所有格形式。

These are Jim's an dTom ' toys.这些是吉姆和汤姆的玩具。
