人稱及物主形式對照
每列依次比較主格、賓格，以及物主限定詞、物主代名詞和反身代名詞。物主限定詞後接名詞；物主代名詞則可獨立使用。
| 主格／賓格 | 物主及反身形式 | 原創例句及說明 |
|---|---|---|
| I / me | my / mine / myself | I found my key. This key is mine. |
| you / you | your / yours / yourself（單數）或 yourselves（複數） | Please help yourselves to some water. |
| he / him | his / his / himself | I gave him his notebook. |
| she / her | her / hers / herself | The blue folder is hers. |
| it / it | its / 一般不用獨立物主形式 / itself | The machine turns itself off. its 表示所屬；it’s 則是 it is 或 it has 的縮寫。 |
| we / us | our / ours / ourselves | We made the poster ourselves. |
| they / them | their / theirs / themselves | Their classroom is next to ours. |
句中位置與反身用法
反身代名詞表示動作回到主語本身，亦可作強調；不應只因想令語氣正式，便以 myself 代替 I 或 me。
| 項目 | 用法及例子 | 說明 |
|---|---|---|
| 主格與賓格 | She called him. / Please sit beside me. | 主語用 she；動詞或介詞的賓語位置用 him、me。 |
| 物主限定詞與物主代名詞 | This is her pen. / This pen is hers. | 不寫 hers pen，也不寫 This pen is her。 |
| 反身與強調 | He hurt himself. / I checked it myself. | 前者指他自己受傷；後者強調是我親自檢查。 |
| by oneself | She travelled by herself. | 可表示獨自一人；須按語境理解是否強調沒有他人協助。 |
不定代詞及指代清晰
指代詞的對象須讓讀者清楚辨認，尤其一句內出現多名同性人物時。
| 項目 | 用法及例子 | 說明 |
|---|---|---|
| everyone / somebody | Everyone has a copy. | 這類不定代詞一般配合單數動詞；後文可按語境使用單數 they。 |
| each / both | Each of the students has a copy. / Both students have copies. | each 着重個別，一般用單數動詞；both 指兩者，用複數。 |
| 指代不清 | Amy told May that Amy had lost the book. | 若 she 可能指 Amy 或 May，重複名字反而更清楚。 |
