# 第一册 Lesson 127 A famous actress 著名的女演员

## 一、课文原文

Listen to the tape then answer this question. Who is only twenty-nine, and why is it so unclear?

**KATE:** Can you recognize that woman, Millie?

**MILLIE:** I think I can, Kate. It must be Karen Marsh, the actress.

**KATE:** I thought so. Who's that beside her?

**MILLIE:** That must be Conrad Reeves.

**KATE:** Conrad Reeves, the actor? It can't be. Let me have another look. I think you're right! Isn't he her third husband?

**MILLIE:** No. He must be her fourth or fifth.

**KATE:** Doesn't Karen Marsh look old!

**MILLIE:** She does, doesn't she! I read she's twenty-nine, but she must be at least forty.

**KATE:** I'm sure she is.

**MILLIE:** She was a famous actress when I was still a schoolgirl.

**KATE:** That was a long time ago, wasn't it?

**MILLIE:** Not that long ago! I'm not more than twenty-nine myself.

## 三、语法知识点

### 情态动词表推测：must 和 can't

| 情态动词 | 推测语气 | 含义 | 例句 |
|----------|----------|------|------|
| must be | 肯定推测 | 一定是 | It must be Karen Marsh.（一定是卡伦·马什。） |
| can't be | 否定推测 | 不可能 | It can't be Conrad Reeves.（不可能是康拉德·里夫斯。） |
| may/might be | 可能推测 | 可能是 | She may be forty.（她可能四十岁。） |

**重要规则：**
- 表推测的**否定**不用mustn't，而用**can't**
- mustn't表示"禁止"，不表示"不可能"
- can't表示"不可能"，语气较强

**时态扩展：**

| 时态 | 结构 | 例句 |
|------|------|------|
| 对现在的事实推测 | must/can't + 动词原形 | She must be forty. |
| 对正在进行的事推测 | must/can't + be doing | He must be working now. |
| 对过去的事推测 | must/can't + have done | She must have been beautiful. |

## 四、重点句型分析

1. **It must be Karen Marsh, the actress.**
   - must be 表示有把握的肯定推测，"一定是"
   - the actress是Karen Marsh的同位语

2. **It can't be.**
   - can't be 表示有把握的否定推测，"不可能"
   - 完整形式：It can't be Conrad Reeves.

3. **Doesn't Karen Marsh look old!**
   - 否定疑问句形式的感叹句
   - 用降调朗读，表示感叹而非疑问
   - = Karen Marsh looks very old!

4. **She does, doesn't she!**
   - 反意疑问句用于表示附和，语气为感叹
   - 说话者对此深信不疑

5. **She must be at least forty.**
   - must be 推测"一定"
   - at least 至少，修饰数字

6. **Not that long ago!**
   - that作副词，意为"那么"，相当于so
   - = Not so long ago!

## 五、课文翻译

**凯特：** 你能认出那个女人吗，米莉？

**米莉：** 我想我能认出来，凯特。那一定是卡伦·马什，那位女演员。

**凯特：** 我也这么想。她旁边的那个人是谁？

**米莉：** 那一定是康拉德·里夫斯。

**凯特：** 康拉德·里夫斯，那个男演员？不可能。让我再看一眼。我想你说得对！他不是她的第三任丈夫吗？

**米莉：** 不是。他一定是她的第四任或第五任丈夫。

**凯特：** 卡伦·马什看上去真老啊！

**米莉：** 确实，不是吗！我读到她二十九岁，但她一定至少四十岁了。

**凯特：** 我肯定她是的。

**米莉：** 当我还是个女学生的时候，她就是一个著名的女演员了。

**凯特：** 那是很久以前的事了，不是吗？

**米莉：** 也没那么久！我自己也不到二十九岁。

## 六、语言点精讲

1. **must be表推测**：表示根据已有证据做出的肯定推断，语气非常肯定。如：The light is on. She must be at home.（灯亮着，她一定在家。）

2. **can't be表推测**：表示根据已有证据做出的否定推断，"不可能"。注意不能用mustn't表推测的否定。如：He can't be at home. The door is locked from outside.（他不可能在家。门从外面锁着。）

3. **Doesn't she look old!**：否定疑问句表感叹，读降调。这种句型常用来表达强烈的感情。再如：Isn't it beautiful!（真美啊！）Aren't you lucky!（你真幸运！）

4. **She does, doesn't she!**：此处的反意疑问句不是真正的疑问，而是表示赞同和附和，读降调。

5. **that作副词**：Not that long ago中的that不是代词或连词，而是副词，意为"那么"，相当于so。如：I can't run that fast.（我跑不了那么快。）

6. **at least**：至少。表示对数量的最低估计。如：There were at least fifty people there.（那里至少有五十人。）

## 七、课后练习要点

1. 用must be或can't be填空，练习推测语气
2. 区分mustn't（禁止）和can't（不可能）的用法
3. 将直接观察转化为推测表达
4. 翻译含推测语气的句子

## 八、本课小结

- **核心语法**：情态动词表推测——must be（一定）和can't be（不可能）
- **关键规则**：表推测的否定用can't，不用mustn't；mustn't只表示"禁止"
- **重点词汇**：famous, recognize, beside, at least
- **重要句型**：否定疑问句表感叹；that作副词表"那么"
- **交际功能**：辨认人物并做出推测
