详细解析

P - Point（论点）

段落的开头句，明确提出你要论证的观点。

句式:

• One significant advantage/disadvantage is that...
• A key reason for this is...
• Another important point to consider is...

错误示范:

• ❌ "There are many reasons..." (太笼统)
• ❌ "I think education is important." (无具体论点)

---

E - Explain（解释）

解释为什么这个论点成立，阐述因果关系和逻辑。

句式:

• This is because... / The reason is that...
• By doing so, ... / In this way, ...
• This phenomenon can be explained by...

关键:

• 不要直接跳到例子
• 解释是连接论点和例子的桥梁

---

E - Example/Evidence（举例）

用具体事例或数据支持你的论点。

类型:

类型	示例
具体国家	In Finland, ...
研究数据	Studies have shown that...
假设场景	For instance, if a student...
普遍现象	In many workplaces, ...

句式:

• For example, ... / For instance, ...
• A clear illustration of this is...
• This can be seen in...

[!TIP] 不一定需要真实数据。合理的普遍性描述也可以作为证据。

---

L - Link（回扣）

总结本段论证，回扣主题或过渡到下一段。

句式:

• Therefore, it is clear that...
• This demonstrates why...
• Thus, [重述论点] is essential.

题目: Some people believe that governments should invest more in public transport. Do you agree?

PEEL 段落:

[P] One compelling reason to increase investment in public transport is its potential to reduce urban congestion. [E] When affordable and efficient bus and rail services are available, more commuters are likely to leave their cars at home, thereby reducing the number of vehicles on the road. [E] For instance, cities like Tokyo and Singapore have demonstrated that well-funded metro systems can handle millions of passengers daily, significantly easing traffic pressure. [L] Therefore, government investment in public transport is a practical solution to the gridlock that plagues many modern cities.

分析

元素	内容
P	投资公共交通可以减少拥堵
E (解释)	人们会选择公交而非开车
E (举例)	东京和新加坡的地铁系统
L	呼应开头，得出结论

常见错误

[!CAUTION]

• ❌ 没有 Explain：Point → Example（逻辑跳跃）
• ❌ 例子太个人化："My friend once..."
• ❌ 没有 Link：段落戛然而止
• ❌ Point 太模糊无法展开

练习：补全 PEEL

题目: Social media has more drawbacks than benefits. Do you agree?

P: One major drawback of social media is its negative impact on mental health.

E (解释): _____________________________________________

E (举例): _____________________________________________

L: _____________________________________________

参考答案:

E: This is because constant exposure to idealized images and lifestyles on platforms like Instagram can lead to feelings of inadequacy and low self-esteem, particularly among young users. E: Research has shown that teenagers who spend more than three hours daily on social media are twice as likely to report symptoms of anxiety and depression. L: Thus, the psychological harm caused by social media is a significant concern that cannot be overlooked.
