课文原文
**Lesson 20: One man in a boat 独坐孤舟**
**参考译文：**
钓鱼是我最喜欢的一项运动。我经常一钓就是几个小时，却什么也钓不到。但这并不使我烦恼。有些钓鱼人运气不好。他们钓不到鱼，反而钓到了旧靴子和垃圾。我运气更糟。我从来什么都钓不到——连旧靴子都钓不到。在河边度过整整一个上午之后，我总是空着袋子回家。"你必须放弃钓鱼！"我的朋友们说。"这是浪费时间。"但他们不明白一件重要的事情。我并不是真的对钓鱼感兴趣。我只是对坐在船上、什么都不做感兴趣！
Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything—not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. ‘You must give up fishing!’ my friends say. ‘It’s a waste of time.’ But they don’t realize one important thing. I’m not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all!
一、词法分析 (Morphology)
1.1 核心词汇词类标注
| 词汇 | 音标 | 词性 | 本课含义 | 词形变化 |
|---|---|---|---|---|
| fishing | /ˈfɪʃɪŋ/ | n. (动名词) | 钓鱼 | fish (v.), fishes (三单) |
| favourite | /ˈfeɪvərɪt/ | adj./n. | 最喜欢的 | — |
| instead of | /ɪnˈsted ɒv/ | 介词短语 | 代替；而不是 | — |

1.2 词形变化要点
1.2.1 动名词变化规则
fish → fishing（钓鱼）
本课例句：
"Fishing is my favourite sport."（钓鱼是我最喜欢的运动。）
"I'm not really interested in fishing."（我不是真的对钓鱼感兴趣。）
规则动词变动名词：
- 一般情况：直接加 -ing (fish → fishing)
- 以不发音e结尾：去e加 -ing (have → having)
- 重读闭音节：双写尾字母加 -ing (sit → sitting)
常见动名词：
| 动词原形 | 动名词 | 本课出现 |
|---|---|---|
| fish | fishing | ✓ (主题词) |
| catch | catching | ✓ without catching |
| spend | spending | ✓ After having spent |
| sit | sitting | ✓ sitting in a boat |
| do | doing | ✓ doing nothing |
| give | giving | give up fishing |
1.2.2 形容词派生
interest 词族：
interest (n./v.) 兴趣/使感兴趣
↓
interested (adj.) 感到感兴趣的 → 主语是人
↓
interesting (adj.) 令人感兴趣的 → 主语是物
用法区别：
- interested: I am interested in fishing. (我对钓鱼感兴趣。)
- interesting: Fishing is interesting. (钓鱼很有趣。)

Fishing (= 动名词作主语)
谓语：

表语：
my favourite sport (名词短语)
语法要点：
1. 【核心语法】动名词作主语

- 谓语动词用单数 (is)
- 相当于：To fish is my favourite sport. (不定式也可作主语，但不如动名词常用)
2. favourite 的用法
- favourite = 最喜欢的 (美式：favorite)
- 前面常有物主代词 (my/his/her)
- 本身已含最高级意义，不与 most 连用

3. 可改写为：

(时间状语从句)
4. whole mornings = 整个上午

4.3 难点解析
难点1：动名词作主语时谓语用单数
✓ Fishing is my favourite sport. (is)
✗ Fishing are my favourite sport. (错误)
规则：
动名词作主语时，谓语动词用单数形式。
Reading books is interesting.
Swimming is good exercise.
难点2：After having done 的特殊性
After having spent whole mornings on the river...
= After I had spent whole mornings on the river...
= Having spent whole mornings on the river, I...
区别：
- After spending... (spending 与主句动作时间关系不明确)
- After having spent... (强调 spending 先于主句动作完成)
- 完成式强调动作的先后顺序
难点3：instead of 的位置和含义
Instead of catching fish, they catch old boots.
= They catch old boots instead of catching fish.
instead of 可以放在句首或句末：
- 句首：Instead of studying, he played games.
- 句末：He played games instead of studying.
含义：不是做A，而是做B (B是实际发生的)
