第三单元：物代
上节课我们学习了my及-’s等表示拥有的形容词。其中，只有-’s是可以兼做定语和表语的，my等一众词只能做定语。 本节课我们继续学习这些表示拥有的词的代词形式及“你我他”的宾语形式。
代词版“你我他的”
一
自然推理
从下方示例中推断划线词的意思和用法。
1. This is my cat. → The cat ismine.
2. This is your car. → The car is
yours.
3. This is his house. → The house is
his.
4. This is her hat. → The hat is
hers.
5. These are our photos. → These photos are
ours.
6. Those are their books. → Those books are
theirs.

英文中用mine等词做表示拥有意思的代词，在上述句子中作表语。与做定语的“拥有”对应关系如下：
1. my – mine /main/
2. your – yours /jɔ:z/
3. his – his /hiz/
4. her – hers /hə:z/
5. our – ours /’auəz/
6. their – theirs /ðɛəz/
除了mine之外，“代词版拥有”是在“定语版拥有”的词尾加上-s。定语版的his已经是-s结尾，因此表语版的就不再叠加s了。 its不作表语！可以说They are its legs. 但不说The legs are its！
二
知识点：物主代词
mine等词在术语中称为“物主代词”，即表明事物拥有者的代词。
这类词的代词属性体现在它们既可以做表语，也可以做主语和宾语。比如：
✓ This computer ismine. 【表语】(computer / /kəm’pju:tə/ 计算机) ✓Mineis a pink computer. 【主语】(pink /pink/ 粉红的) ✓ Please usemine. 【宾语】(use /ju:z/ 使用)
-’s除了形容词之外，也可作代词，词法上可视为my/mine的结合。比如：
✓ That computer isJack’s. 【表语】 ✓Jack’sis a yellow computer. (yellow /’jeləu/ 黄色的) 【主语】 ✓I likeJack’s. 【宾语】
宾语版“你我他”
I / you / he / she / it / we / they 等词的词性也是代词，但它们都只能做主语。用作宾语或表语时需要改变形式。

自然推理
研究总结下方示例中宾语人称的形式。
1. I need you! Give me your hand. (give
sb. a/one’s hand给予帮助)
2. He needs help! Give him a hand. (help /help/
帮助)
3. She needs help! Give her a hand.
4. It needs help! Give it a hand.
5. We need help! Give us a hand.
6. They need help! Give them a hand.

依样画葫芦
下列句子中，人称代词处于表语的位置，形式与宾语相同。
-Who’s that?
-It’s me / him / her / us / them!
其实在Thank you!中的you也是宾语！只不过表示“你”或“你们”时，主语宾语都是you。
实践
用提示词的正确形式填入句子。
1. Please let ___ (I) try! ____ (he)
really needs ____ (we) help! (try /trai/ 尝试)

3. This yellow hat is ____ (I) ____ (sister). ____ (he) is pink.
