让步反转句 (Concession)

核心逻辑：欲扬先抑。承认对方观点的合理性，然后指出其局限性或反驳。

1. 经典句型

A. Although / While (尽管...)

放句首，引导从句。

• While it is true that [Opposing View], I believe that [My View].
• Although industrialization brings economic growth, the environmental cost is too high.

B. Admittedly / It is true that (诚然...)

分两个句子写，更强调语气。

• Admittedly, studying abroad is expensive. However, the cultural experience is priceless.
• It is true that AI can improve efficiency. Nevertheless, it lacks human creativity.

2. 这里的 "May" 很重要

在让步部分，常配合情态动词 may / might / could 表示“可能/确实”。

• Opponents may argue that... However, ...
• This approach might seem effective in the short term, but...

3. 实战应用

题目: Should museums be free? 让步段: Admittedly, abolishing entry fees may reduce revenue for museum maintenance. (承认缺钱) However, this financial loss can be offset by government subsidies and souvenir sales. (反驳/解决方案)
