**Lesson 34: Quick work 破案"神速"**
**参考译文**：
特德·鲁滨逊整个星期都很担心。上周二他收到当地警方的一封信。信中他被要求去警察局一趟。特德想知道为什么警方要找他，但他昨天去了警察局，现在他不再担心了。在警察局，一位面带微笑的警察告诉他，他的自行车找到了。警察告诉他，五天前自行车在四百英里外的一个小村庄被找到。它现在正通过火车被送往他家。特德听到这个消息时非常惊讶。他也觉得好笑，因为他从未指望自行车能被找到。它是在二十年前特德十五岁时被偷的！
Ted Robinson has been worried all the week. Last Tuesday he received a letter from the local police. In the letter he was asked to call at the station. Ted wondered why he was wanted by the police, but he went to the station yesterday and now he is not worried any more. At the station, he was told by a smiling policeman that his bicycle had been found. Five days ago, the policeman told him, the bicycle was picked up in a small village four hundred miles away. It is now being sent to his home by train. Ted was most surprised when he heard the news. He was amused too, because he never expected the bicycle to be found. It was stolen twenty years ago when Ted was a boy of fifteen!

3.3 时间状语从句 (Adverbial Clause of Time)
3.3.1 本课时间状语从句
| 句子 | 连词 | 从句内容 | 主句动作 |
|---|---|---|---|
| S8 | when | he heard the news | was surprised |
| S11 | when | Ted was a boy of fifteen | was stolen |
3.3.2 when引导的时间状语从句
用法特点：
1. 可置于主句前或后
When he heard the news, Ted was surprised.
Ted was surprised when he heard the news.
2. 时态配合（时间呼应）
- 主句过去时，从句也用过去时
- 主句过去完成时，从句用一般过去时
例：
He never expected the bicycle to be found
when it was stolen twenty years ago.
3.4 宾语从句 (Object Clause)
3.4.1 本课宾语从句
| 句子 | 引导词 | 从句位置 | 例句 |
|---|---|---|---|
| S4 | why | wonder的宾语 | Ted wondered why he was wanted… |
| S5 | that | told的宾语 | …was told… that his bicycle had been found |

3.5.2 用法解析
时间轴示意：
─────────────────────────────────────────→
过去① 过去② 现在
(找到车) (被告知) (叙述时)
↓ ↓
had been found was told
规则：
"过去的过去"用过去完成时
构成：had + 过去分词 (P.P.)
常见搭配：
| 时间标志 | 例句 |
|---|---|
| by + 过去时间 | By yesterday, the bicycle had been found. |
| before + 从句 | Before he went, the news had spread. |
| after + 从句 | After the bicycle had been stolen, … |
四、难点解析
4.1 “wanted by the police” 的理解
wanted 在本课有两个含义：
1. "被通缉"（表面意思，Ted的误解）
2. "被要求/需要找"（实际意思）
双关效果：
- Ted wondered why he was wanted by the police
（Ted以为：为什么我被通缉了？）
（实际意思：为什么警察要找我？）
这种"悬念-揭晓"的结构是本文的幽默来源之一。
4.2 被动语态中的by短语
by短语表示"施事者"（动作执行者），但不是必须的。
本课带by的句子：
- he was asked... (隐含：by the police)
- he was wanted **by the police**
- he was told **by a smiling policeman**
- was picked up (无by，执行者未知/不重要)
- was sent (无by，执行者不重要)
- was stolen (无by，执行者未知)
4.3 “most surprised” 不是最高级
most + 形容词 = "非常..."（强调程度）
≠ the most + 形容词（最高级）
对比：
- Ted was **most surprised**. (非常惊讶)
- This is **the most surprising** news. (最令人惊讶的)
