在辩论中，提问是关键环节，有效的提问可以引导对方思考、揭示逻辑漏洞或引入新观点。以下是常用的英语提问表达及使用场景：

一、直接询问观点类

I wonder your opinion on...

用于开场或转折时，引导对方表达对特定问题的看法。

- 例：I wonder your opinion on the effectiveness of online education.

I'd like to hear your perspective on...

更正式的表达，适用于学术或正式场合。

- 例：I'd like to hear your perspective on the ethical implications of AI.

二、引导深入思考类

Could you elaborate on your argument？

鼓励对方进一步解释观点或论据。

- 例：Could you elaborate on your argument regarding the economic impact of tariffs？

What evidence do you have to support your claim？

直接质疑对方论据的依据。

- 例：What evidence do you have to support your claim that this policy is effective？

三、揭示逻辑漏洞类

You are generalizing what I asked!

当对方以偏概全时使用，要求其具体化问题。

- 例：You are generalizing what I asked! I was specifically interested in the short-term effects.

This argument seems to be based on a flawed premise

明确指出对方论据的逻辑缺陷。

- 例：This argument seems to be based on a flawed premise. The data you cited is outdated.

四、控制辩论节奏类

Please answer my question!

在自由辩论阶段，用于打断对方的冗长论述。

- 例：Please answer my question! The relevance of your example is unclear.

Let's focus on the main issue

引导辩论回到核心议题，避免偏题。

- 例：Let's focus on the main issue. The details are irrelevant to our argument.

五、补充说明类

In addition to your argument, have you considered...

提出新的视角或补充信息。

- 例：In addition to your argument, have you considered the social impact of this policy？

使用这些表达时需注意：

语境选择：正式辩论建议使用I wonder/you'd like to hear等礼貌用语，非正式场合可用更直接的表达。

时机把握：提问应避免打断对方思路，需在对方发言后适时插入。

逻辑关联：提问后应预留时间给对方回应，避免连续攻击。

通过灵活运用这些提问技巧，可以提升辩论的深度和效率。
