课文原文

**Lesson 58: A blessing in disguise? 是因祸得福吗？**

The tiny village of Frinley is said to possess a ‘cursed tree’. Because the tree was mentioned in a newspaper, the number of visitors to Frinley has now increased. The tree was planted near a church fifty years ago, but it is only in recent years that it has gained an evil reputation. It is said that if anyone touches the tree, he will have bad luck; if he picks a leaf, he will die. Many villagers believe that the tree has already claimed a number of victims. The vicar has been asked to have the tree cut down, but so far he has refused. He has pointed out that the tree is a useful source of income as tourists have been coming from all parts of the country to see it. In spite of all that has been said, the tourists have been picking leaves and cutting their names on the tree-trunk. So far, not one of them has been struck down by sudden death!

**参考译文**：据说弗林利这个小村庄拥有一棵"被诅咒的树"。因为这棵树被报纸提及，现在来弗林利的游客数量增加了。这棵树是五十年前种在教堂附近的，但直到最近几年它才获得恶名。据说如果有人触摸这棵树，他就会有厄运；如果他摘一片叶子，他就会死。许多村民相信这棵树已经夺去了许多受害者的生命。牧师被要求把这棵树砍掉，但到目前为止他拒绝了。他指出这棵树是有用的收入来源，因为游客一直从全国各地来看它。尽管已经说了这么多，游客们一直在摘树叶并把他们的名字刻在树干上。到目前为止，他们中没有一个人被猝死击倒！

3.1.1 时态分布统计

时态	出现次数	例句	功能
一般现在时	2	is said, touches	陈述事实、条件从句
一般过去时	2	was mentioned, was planted	明确过去时间的事件

3.1.2 时态关系时间轴

时间轴示意图：

过去 ──────────────────────────────────────────────────► 现在

     fifty years ago
     [was planted] ──────►
                              
     was mentioned ────────► has now increased
                              
     only in recent years ──► has gained

                            has been struck down?
                            （答案：否定）

3.2 语态分析

3.2.1 被动语态统计

语态类型	例句	时态	功能
一般现在时被动	is said to possess	is + done	客观陈述
一般过去时被动	was mentioned, was planted	was + done	过去被动事件
现在完成时被动	has been asked, has been struck down	has been + done	到现在完成的被动
现在完成时被动（从句）	has been said	has been + done	被说过的内容

3.2.2 被动语态详解

1. be said to… 结构

公式：主语 + be said + to + 动词原形

本课例句：
The tiny village... is said to possess a 'cursed tree'.
据说这个小村庄拥有一棵"被诅咒的树"。

扩展结构：
- be said to do = 据说做...
- be said to be doing = 据说正在做...
- be said to have done = 据说已经做了...

2. It is said that… 结构

公式：It + be said + that从句

本课例句：
It is said that if anyone touches the tree, he will have bad luck...
据说如果有人触摸这棵树，他就会有厄运...

与 be said to 的区别：
- be said to: 后面接不定式，主语是动作执行者
- It is said that: 后面接从句，更正式

3.3 强调句型分析

3.3.1 It is…that… 强调句型

基本结构：
It is/was + 被强调部分 + that/who + 其余部分

本课例句：
it is only in recent years that it has gained an evil reputation.

分析：
- 被强调部分：only in recent years（时间状语）
- 连接词：that（强调物或时间用that，强调人用who/that）
- 其余部分：it has gained an evil reputation

还原为非强调句：
It has gained an evil reputation only in recent years.

强调句型判断方法：
去掉It is/was...that后，剩余部分能组成完整句子 → 是强调句
本课验证：Only in recent years it has gained an evil reputation. ✓（成立）

3.4 have sth. done 结构分析

3.4.1 结构详解

基本含义：让某事被做（由他人完成）

公式：have + 宾语 + 过去分词（宾语补足语）

本课例句：
have the tree cut down = 让人把树砍掉

结构分析：
- have: 使役动词，"使；让"
- the tree: 宾语（动作的承受者）
- cut down: 过去分词（作宾补，表被动）

其他例句：
- have my hair cut = 理发（让别人剪）
- have the car repaired = 让人修车
- have the room cleaned = 让人打扫房间

注意区分：
have sth. done（让某事被做）vs. have done sth.（已经做了某事）

3.5 条件状语从句分析

3.5.1 真实条件句

本课例句：
if anyone touches the tree, he will have bad luck
if he picks a leaf, he will die

结构：
If + 主语 + 一般现在时，主语 + will + 动词原形

语法规则（主将从现）：
- 条件从句用一般现在时表示将来
- 主句用一般将来时

条件类型：
- 第一类条件句（真实条件）：表示可能发生的事情
- 本课描述的是一种传说/警告，但在语法上属于真实条件句框架

3.6 so far 与现在完成时

3.6.1 搭配规则

so far = up to now = until now = 到目前为止

用法特点：
1. 必须与现在完成时（或现在完成进行时）连用
2. 强调从过去某时到现在的情况

本课例句：
- So far, he has refused. (S6)
- So far, not one of them has been struck down... (S9)

常见错误：
✗ So far, he refused. （时态错误）
✓ So far, he has refused. （正确）

3.7 In spite of 让步结构

3.7.1 用法详解

in spite of = despite = 尽管；虽然

语法特点：
- 是复合介词，后接名词、代词或动名词
- 不能后接完整句子（需用 although/though/even though）

本课例句：
In spite of all that has been said, ...
尽管已经说了这么多，...

结构分析：
- In spite of: 复合介词
- all: 代词作宾语
- that has been said: 定语从句修饰all

对比：
- In spite of the rain, we went out. （接名词）✓
- Although it rained, we went out. （接从句）✓
- In spite of it rained... ✗（错误：不能接句子）

3.8 not one of… 部分否定

3.8.1 否定结构分析

本课例句：
not one of them has been struck down
他们中没有一个人被击倒

结构特点：
1. not one of + 复数代词/名词 = 完全否定（没有一个人）
2. 谓语动词用单数（one是中心词）

对比：
| 结构 | 含义 | 谓语 | 例句 |
|------|------|------|------|
| not one of them | 没有一个人 | 单数 | Not one of them is here. |
| none of them | 没有一个人 | 单数/复数 | None of them is/are here. |
| not all of them | 并非所有人 | 复数 | Not all of them are here. |

注意：
- not one of... 表示完全否定
- not all of... 表示部分否定（并非所有）

4.2 难句深度解析

难句1：嵌套最多的句子

He has pointed out that the tree is a useful source of income as tourists have been coming from all parts of the country to see it.

【分层拆解】

第一层（主句）：
He has pointed out
他指出

第二层（宾语从句）：
that the tree is a useful source of income
这棵树是有用的收入来源

第三层（原因状语从句）：
as tourists have been coming from all parts of the country to see it
因为游客一直从全国各地来看它

【句子特点】
- 共3层嵌套
- 涉及现在完成时、现在完成进行时
- as引导原因状语从句（= because）

【翻译技巧】
先理清逻辑关系：
"他指出[这棵树是有用的收入来源]，因为[游客一直从全国各地来看它]。"

难句2：语法点最密集的句子

So far, not one of them has been struck down by sudden death!

【分层拆解】

主干：
not one of them has been struck down
他们中没有一个人被击倒

状语：
- So far: 时间状语（到目前为止）
- by sudden death: 施事状语（被猝死）

【语法价值】
- 时间状语 so far
- 部分否定 not one of
- 现在完成时被动语态
- 主谓一致（单数谓语）

【理解关键】
- not one of them = 完全否定（没有一个人）
- has been struck down = 现在完成时被动
- by sudden death = 被猝死（讽刺：诅咒并未应验）
