## 二、重点词汇详解

| 单词 | 音标 | 词性 | 释义 | 用法说明 |
|------|------|------|------|----------|
| his | /hɪz/ | possessive pron. | 他的 | 物主代词，可独立使用 |
| her | /hɜːr/ | possessive adj. | 她的 | 物主形容词，后接名词 |

## 三、语法知识点

### 1. 物主代词分类

| 类型 | 我的 | 你的 | 他的 | 她的 | 它的 |
|------|------|------|------|------|------|
| 形容词性物主代词 | my | your | his | her | its |
| 名词性物主代词 | mine | yours | his | hers | its |

**形容词性物主代词**：后必须接名词 → my shirt, her handbag
**名词性物主代词**：独立使用，等于形容词性+名词 → mine = my shirt

### 2. Whose 的两种句式

| 句式 | 例句 |
|------|------|
| Whose + 名词 + is this? | Whose shirt is this? |
| Whose is this + 名词? | Whose is this shirt? |

两种句式含义相同，可互换使用。

### 3. 回答 Whose 句型

| 回答方式 | 例句 |
|----------|------|
| 用名词所有格 | It's Tim's. |
| 用物主代词+名词 | It's his shirt. |

## 四、重点句型分析

### Whose is this/that...?

- Whose is this handbag? — It's Sophie's. It's her handbag.
- Whose is that car? — It's Steven's. It's his car.

**句型转换**：
- Whose is this shirt? = Whose shirt is this?
- 回答：It's Tim's. = It's his (shirt).

## 五、课文翻译

这件衬衫是谁的？——是蒂姆的。这是他的衬衫。
那件衬衫是谁的？——是戴夫的。这是他的衬衫。
这个手提包是谁的？——是索菲的。这是她的手提包。
那辆汽车是谁的？——是史蒂文的。这是他的汽车。
这件外套是谁的？——是罗伯特的。这是他的外套。
那把雨伞是谁的？——是保罗的。这是他的雨伞。

## 六、语言点精讲

1. **his 既可作形容词性物主代词也可作名词性物主代词**，这是唯一一个两种形式相同的词。

2. **her** 只能作形容词性物主代词，名词性形式为 **hers**。

3. **It's Tim's** 中的 's 是所有格，It's = It is 中的 's 是 is 的缩写。两个 's 含义不同。

## 七、课后练习要点

1. 掌握物主代词两种形式的用法
2. 练习 Whose 句型的问答
3. 区分 his 和 her 的用法
