mine, yours, hers (A2)

你已经会用 my, your, her 了。如果不想再重复说那个东西，就换成 mine, yours, hers：my book → mine。

my book = mine

• This is my book. = This book is mine.
• That is your seat. = That seat is yours.
• It is her bag. = The bag is hers.
• Not "This book is my." — say "This book is mine.". 后面不带东西的时候，my 就变成 mine。
• 试一试: That seat is ___. (yours / your / your's) 答案: yours — 这里后面什么都没有，所以用 yours，不是 your（your 后面必须跟一个东西，比如 "your seat"）。而且这里没有撇号：yours。

完整的一组

这是完整的对照表：I → mine, you → yours, he → his, she → hers, we → ours, they → theirs。注意：his 还是 his，mine 后面没有 -s（不是 "mines"）。

• Is this pen yours? No, it is his.
• These tickets are ours, not theirs.
• The red coat is hers.
• 试一试: This phone isn't yours, it's ___. (mine / mines / my) 答案: mine — 这个词是 mine，后面没有 -s（不是 "mines"）。这里后面也没有东西跟着，所以也不能用 "my"：it's mine。

后面不跟东西

像 mine, yours, hers 这样的词是单独用的，后面不要加东西。如果想说清楚是什么东西，就要换回 my, your, her。

• Those keys are theirs. (not "theirs keys")
• Is this yours? (not "yours bag")
• It is her phone. = The phone is hers.
• Not "That is hers bag." — say "That is her bag. / That bag is hers.". 说清楚东西 → her bag。后面不加东西 → hers。
• 试一试: Those are ___ keys. (their / theirs / theirs') 答案: their — 后面紧跟着一个东西（keys），所以用 their + keys。"Theirs" 是单独用的，后面不加东西："Those keys are theirs."
• 试一试: Is this ___ umbrella? No, I think it's ___. (your … hers / yours … hers / your … her) 答案: your … hers — 第一个空后面跟着东西（umbrella）→ your umbrella。第二个空是单独用的 → hers。后面跟东西用 your/her；单独用就用 yours/hers。
