课文原文

**Lesson 18 He often does this! 他经常干这种事！**

After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn’t there! As I was looking for it, the inn-keeper came in. ‘Did you have a good meal?’ he asked. ‘Yes, thank you,’ I answered, ‘but I can’t pay the bill. I haven’t got my bag.’ The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. ‘I’m very sorry,’ he said. ‘My dog had taken it into the garden. He often does this.’

**参考译文：**

我在一家乡村小旅店吃过午饭后，寻找我的手提包。我把它放在门边的一把椅子上，现在不见了！当我正在寻找时，旅店老板走了进来。“您吃得好吗？“他问。“是的，谢谢，“我回答，“但我付不了账。我的手提包不见了。“旅店老板笑了笑，立即走了出去。几分钟后他带着我的手提包回来，还给了我。“非常抱歉，“他说，“我的狗把它拿到花园里去了。它经常干这种事。“

一、核心语法点详解

1.1 过去完成时 (Past Perfect Tense)

本课是过去完成时的经典教学范例，课文中共出现3处过去完成时。

1.1.1 结构形式

肯定式：had + 过去分词 (had done)
否定式：had not / hadn't + 过去分词
疑问式：Had + 主语 + 过去分词?

1.1.2 本课实例分析

例句1：After I had had lunch at a village inn, I looked for my bag.

时间线分析：
─────────────────────────────────────────────────►
        ↑ had had lunch          ↑ looked for
      （先发生）               （后发生）
        ─────过去完成时────────  一般过去时─────►

逻辑关系："吃午饭"发生在"寻找"之前，是"过去的过去"

语法要点：

had had：第一个 had 是助动词，第二个 had 是实义动词 have 的过去分词
after 引导的时间状语从句使用过去完成时，强调动作的先后顺序

例句2：I had left it on a chair beside the door and now it wasn’t there!

时间线分析：
─────────────────────────────────────────────────►
        ↑ left it on chair       ↑ looking for
      （先发生）               （发现不见）
        ─────过去完成时────────  过去/现在─────►

语义功能：强调"放包"这个动作发生在"发现不见"之前

例句3：My dog had taken it into the garden.

时间线分析：
─────────────────────────────────────────────────►
        ↑ dog took bag           ↑ returned with bag
      （狗叼走）               （找回包包）
        ─────过去完成时────────  一般过去时─────►

语义功能：解释包包不见的原因——在老板找回来之前，狗已经把它叼走了

1.1.3 过去完成时的使用条件

使用场景	本课体现	时间关系
表示”过去的过去”	had had lunch → looked for	先吃后找
解释过去某事的原因	had left it → now wasn’t there	先放后丢
叙述过去事件的先后顺序	had taken it → returned	先叼后还

1.1.4 与一般过去时的对比

时态	结构	时间参照点	例句
一般过去时	did	现在为参照	I looked for my bag.
过去完成时	had done	过去为参照	I had left it on a chair.

时间参照示意图：
现在 ◄───────────────────────────────────► 过去
      ↑                                    ↑
   说话时间                            过去参照点
                                           ↑
                                        had left (更早)
                                           ↓
                                        looked (较近)

1.2 过去进行时 (Past Continuous Tense)

1.2.1 结构形式

肯定式：was/were + 现在分词 (doing)
否定式：was/were not + 现在分词
疑问式：Was/Were + 主语 + 现在分词?

1.2.2 本课实例分析

例句：As I was looking for it, the inn-keeper came in.

时间关系图解：
────────────────────────────────────────►
     ┌─────────────────┐
     │ was looking for │ ← 持续进行的背景动作（长）
     └─────────────────┘
           ↑
       came in ← 突然发生的打断动作（短）

语法要点：

was looking：过去进行时，表示过去某一时刻正在进行的持续性动作
came in：一般过去时，表示突然发生的短暂动作
as：引导时间状语从句，表示”当……时候”

1.2.3 过去进行时的功能

功能	本课体现	说明
描述背景场景	As I was looking for it	设置故事发生的背景
表示动作被打断	…when/while… came in	长动作被短动作打断
强调持续性	was looking（持续寻找）	与瞬间动词形成对比

1.3 时间状语从句 (Adverbial Clause of Time)

本课出现2个时间状语从句，分别由 after 和 as 引导。

1.3.1 After 引导的时间状语从句

结构：After + 从句（过去完成时）, 主句（一般过去时）

本课例句：After I had had lunch at a village inn, I looked for my bag.

句子成分分析：
[时间状语从句] After I had had lunch at a village inn
    ├── 连词: After（在……之后）
    ├── 主语: I
    ├── 谓语: had had（过去完成时）
    └── 状语: at a village inn（地点）

[主句] I looked for my bag
    ├── 主语: I
    └── 谓语: looked for（一般过去时）

逻辑关系：先吃饭 → 后找包

时态搭配规律：

after 从句用过去完成时（先发生的动作）
主句用一般过去时（后发生的动作）

1.3.2 As 引导的时间状语从句

结构：As + 从句（过去进行时）, 主句（一般过去时）

本课例句：As I was looking for it, the inn-keeper came in.

句子成分分析：
[时间状语从句] As I was looking for it
    ├── 连词: As（当……时候）
    ├── 主语: I

    └── 宾语: for it

[主句] the inn-keeper came in
    ├── 主语: the inn-keeper
    └── 谓语: came in（一般过去时）

逻辑关系：正在寻找时 → 老板突然进来

As 的语义特征：

强调两个动作同时发生
常表示”一边……一边……”或”正当……时”

1.3.3 时间状语从句连词对比

连词	含义	时态搭配	本课体现
after	在……之后	从句had done，主句did	After I had had lunch, I looked…
as	当……时	从句was doing，主句did	As I was looking, … came…

before	在……之前	从句did/had done，主句had done/did	—

1.4 直接引语 (Direct Speech)

本课包含4处直接引语，展现了生动的对话场景。

1.4.1 直接引语的结构形式

基本结构："引语内容," 说话者动词.
例句："Did you have a good meal?" he asked.

1.4.2 本课直接引语逐句分析

对话1：问候

‘Did you have a good meal?’ he asked.

结构分析：
[直接引语] "Did you have a good meal?"
    ├── 句式: 一般疑问句
    ├── 时态: 一般过去时
    └── 功能: 礼貌询问用餐体验

[引述分句] he asked
    ├── 主语: he（指 the inn-keeper）
    └── 谓语: asked（一般过去时）

对话2：回答（肯定+转折）

‘Yes, thank you,’ I answered, ‘but I can’t pay the bill. I haven’t got my bag.’

结构分析：
[直接引语第一部分] "Yes, thank you,"
    ├── 功能: 礼貌回应问候
    └── 标点: 逗号在引号内，后接引述分句

[引述分句] I answered
    ├── 位置: 插入在引语中间
    └── 作用: 标明说话者

[直接引语第二部分] "but I can't pay the bill. I haven't got my bag."
    ├── 功能: 说明困境（没钱付账）
    ├── 时态: can't（现在时），haven't got（现在完成时）
    └── 注意: 直接引语中时态与说话时刻一致，不按主句时态变化

对话3：道歉+解释

‘I’m very sorry,’ he said. ‘My dog had taken it into the garden. He often does this.‘

结构分析：
[直接引语第一句] "I'm very sorry,"

[直接引语第二句] "My dog had taken it into the garden."
    ├── 功能: 解释事情原委
    ├── 时态: had taken（过去完成时）← 注意：这是叙述过去的过去
    └── 语义: 说明包包被狗叼走发生在说话之前

    ├── 功能: 补充说明（狗的习性）
    ├── 时态: does（一般现在时）← 表示习惯性动作
    └── 人称: He 指代 my dog

1.4.3 直接引语中时态的特点

直接引语内容	时态	时态选择理由
Did you have…?	一般过去时	询问已发生的用餐
Yes, thank you	一般现在时	礼貌用语，无时间性
I can’t pay…	一般现在时	说话时”不能付”的状态
I haven’t got…	现在完成时	说话时”没有包包”的结果
I’m very sorry	一般现在时	说话时表达歉意
My dog had taken…	过去完成时	说话时”过去的过去”
He often does this	一般现在时	表示习惯、经常性动作

关键洞察：
在直接引语中，时态的选择取决于"说话者说话那一刻"的时间参照点，
而不是叙述者讲故事的时间点。
