小学英语人称代词和物主代词对照学习:I、me、my、mine的区别与句子用法
孩子写句子经常冒出这种话：My is Tom.I book is new.This is me book.
家长一看就急：I、me、my、mine 明明都背过，怎么一用就乱？
问题不在背没背过，在于中文只给了孩子一个"我"，英文却要拿出四张脸。这篇把四张脸一次对照清楚——1 张总表 + 4 步定位法 + 24 句实操 + 7 天计划。
先看病根：中文一个"我"，英文四张脸
中文的"我"很省事——"我上学""给我书""我的书包"，写法基本不变，位置怎么挪都是同一个字。
英文不行：同样是"我"，当主语用 I，跟在动词或介词后面用 me，后面要接名词用 my，句子末尾单独站着用 mine。
孩子出错的根因不是记不住这四个词，而是用中文"一个词走天下"的习惯，去套英文"按位置换形式"的规则。
My is Tom.
I book is new.
This is me book.
This book is my.
I am Tom.
My book is new.
This is my book.
This book is mine.
记住一句话就够：英文里"我"用哪张脸，不由你想说什么决定，由它站在句子的哪个位置决定。
判断顺序永远是先看位置、再选形式。位置没判清就先去背四个单词，背十遍还是错——因为同一个词在不同位置本来就该换脸。
一张总表：7 个人称 × 4 种形式
下面这张表是全篇的根。不用一次背完，但要让孩子知道：英文的代词是一张网，不是七个孤立的词。
| 人称 | 主格 | 宾格 | 形容词性物主 | 名词性物主 | 中文 |
|---|---|---|---|---|---|
| I | me | my | mine | ||
| you | you | your | yours | ||
| he | him | his | his | ||
| she | her | her | hers | ||
| it | it | its | its | ||
| we | us | our | ours | ||
| they | them | their | theirs |
表里有三处特殊，先点出来免得孩子以为漏了行：you 的主格宾格同形（都是 you）；his 和 its 的形容词性、名词性同形（his book / The book is his）；her 一张脸干两份活（her bag 是"她的书包"，I know her 是"我认识她"）。
所以真正要下功夫的只有 5 组"加 s 变名词性"：my→mine、your→yours、her→hers、our→ours、their→theirs。
只有第一人称单数 I 永远大写，哪怕它出现在句子中间：My brother and I are students.
4 步定位法：看位置定形式
遇到空格不知道怎么填？按这 4 步走，每一步只问一个问题。
它是句子里"发起动作的人"吗？是 → 主格：I / he / she / we / they
它跟在动词或介词后面吗？是 → 宾格：me / him / her / us / them
它后面紧跟着一个名词吗？是 → 形容词性物主：my / your / his / her / its / our / their
它后面没有名词、单独站着吗？是 → 名词性物主：mine / yours / his / hers / its / ours / theirs
4 步口诀：「主语用主格，动介后面用宾格；后接名词用 my，单独站着用 mine。」
第 3、4 步是绝大多数丢分点——两个都翻成"我的"，孩子几乎靠猜。养成"看后面有没有名词"的条件反射，这一整类题立刻能稳。
主格 vs 宾格：中文都是"我"，英文要换脸
主格和宾格的区别，本质是"谁是发起者、谁是承受者"。
I am a student.
He is my brother.
They live here.
Give me the book.
I like him very much.
Can you help us?
This is for me.
Sit next to her.
Come with us.
Who is it? — It's me.
Who wants it? — Me.
（口语回答一律用宾格）
Me am a student.
Give I the book.
This is for he.
He is taller than I.
It's I.
I am a student.
Give me the book.
This is for him.
He is taller than me.
It's me.
最稳的判断法：把代词换成人名读一遍。"Give Tom the book" 通顺，所以换成代词就是 "Give me / him / her the book"。反过来，"Give he" 换成人名不可能变成 "Give Tom" 这种通顺结构。
my vs mine：一个"我的"，两种写法
这两张脸的判断只问一件事：后面有没有名词。
my pen / my name / my school
This is my pen.
（后面一定跟着东西）
This pen is mine.
That one is mine, too.
（后面不接名词）
The red one is mine.
Is this yours or mine?
（相当于"我的东西"）
✕ mine book
✕ mine pen
（要接名词就换回 my）
This book is my.
Mine book is new.
This is mine pen.
The book is my.
This book is mine.
My book is new.
This is my pen.
The book is mine.
一句话记牢：「my 后面有人跟，mine 后面没人跟。」同理，your/yours、her/hers、our/ours、their/theirs 全是同一套逻辑，会一组就会五组。
物主代词后面不能再加 a / an / the：✕ my a pen、✕ the my book，正确是 my pen、my book。
一个"他"走完全流程：he / him / his / his 四张脸
把"他"当成一个完整案例走一遍，孩子就会明白：四张脸不是四个词，是一个词在四个位置的样子。
| 形式 | 出现在什么位置 | 例句 | 中文 |
|---|---|---|---|
| he | He is my teacher. | ||
| him | I know him. / This is for him. | ||
| his | His bag is blue. | ||
| his | The blue bag is his. |
she 比 he 多一张脸：her 既是宾格又是形容词性物主（I know her. / her bag），名词性物主要用 hers（The bag is hers.）。这是小学最容易漏的一处。
汉语干扰的 5 个高频陷阱
下面 5 个坑覆盖了小学阶段绝大多数代词错题，全都是"中文思维直接搬过来"造成的。
「我的（是）」直译成 My
✕ My is Tom.
✓ I am Tom.
漏掉形容词性物主
✕ I book is new. / ✕ This is me book.
✓ My book is new. / ✓ This is my book.
句子末尾的"我的"写成 my
✕ This book is my.
✓ This book is mine.
名词性物主后面硬加名词或冠词
✕ Mine book is new. / ✕ my a pen
✓ My book is new. / ✓ my pen
并列主语用宾格
✕ Me and Tom are friends.
✓ Tom and I are friends.
并列语序：为什么是 Tom and I，不是 I and Tom
这是小学一直考到初中的细节，而且和中文顺序正好相反。
I and Tom are friends.
Me and he are in Class 2.
I and my parents go to the park.
Tom and I are friends.
He and I are in Class 2.
My parents and I go to the park.
英文礼貌原则：把别人放在前面，自己放在最后。中文说"我和汤姆"，英文写 "Tom and I"——顺序刚好倒过来。
顺序调换后，代词的"脸"不跟着变：只要整组词是主语，就一定要用主格。所以是 "Tom and I"，不是 "Tom and me"。
4 类常考题型怎么破
先看空格在什么位置：句首主语选主格，动词介词后选宾格，名词前选形容词性物主，句末选名词性物主。
题目给 I，答案可能是 I / me / my / mine 四种之一。判位置再变形：主语 I，动后 me，名词前 my，单独用 mine。
重点查三处：句末的"我的"是否写成 my（应为 mine）、动词介词后是否用了主格（应为宾格）、物主代词后是否多加了冠词。
先定主语（主格），再定宾语（宾格），最后看名词前的所有格（形容词性物主）。三层定完再落笔。
这四类题有一个通用破题法：永远先定位置、再定形式。先想"这个词在这句话里干什么活"，再想"该用哪张脸"。跳过第一步直接猜，正确率全靠运气。
24 句实操：直接照读，一周就见反应
下面 24 句覆盖四张脸的全部位置。建议每天挑一组（6 句）带读 3 遍，读到孩子不看提示也能自己说完整句。
| 序号 | 英文 | 中文 | 考点 |
|---|---|---|---|
| I am a pupil. | |||
| He is my brother. | |||
| We are in the same class. | |||
| She likes music. | |||
| They come from China. | |||
| You are very kind. | |||
| Give me the pen, please. | |||
| I know him well. | |||
| This gift is for her. | |||
| Come with us. | |||
| Can you help them? | |||
| Who is it? — It's me. | |||
| This is my schoolbag. | |||
| Your English is good. | |||
| His father is a doctor. | |||
| Her hair is long. | |||
| Our teacher is very nice. | |||
| Their house is big. | |||
| This book is mine. | |||
| Is this pen yours? | |||
| The blue bag is his. | |||
| That red one is hers. | |||
| This room is ours. | |||
| Those toys are theirs. |
读的时候让孩子做一件事：每读一句，用手指出这个词是"发起者"还是"承受者"，或者后面有没有名词。手指的动作会把判断变成肌肉记忆，比背规则管用。
代词这块理清之后，孩子会突然发现一个共通规律：第三人称单数加 -s、名词变复数、代词换脸，本质都是"看位置改形式"。
这一条通了，往后学时态、学被动语态，孩子就有一个稳定的判断起点了。
