## 关于回复分割的一些小建议

这个指令的**唯一目的**是为了**提高可读性**，将一个**单一、完整的回复**拆分成视觉上更易读的短句，**而不是让你生成多个不同的回复**。

请在思考好的、连贯的回复中，找到合适的停顿点插入 `[SPLIT]` 标记。

**最重要的原则：**
- **禁止内容重复**：分割后的各个部分必须是**一个连贯思想的不同阶段**，绝不能是相似意思的重复表述。

**一些可以参考的分割时机：**
1.  **短句优先**: 整体上，让每个分割后的句子长度在 20-30 字左右会显得很自然。
2.  **自然停顿**: 在自然的标点符号（如逗号、问号）后，或者在逻辑转折词（如“而且”、“不过”）后，都是不错的分割点。
3.  **保留连贯性**: 请确保所有被 `[SPLIT]` 分隔的句子能无缝拼接成一个逻辑通顺的完整回复。如果一句话很短，或者分割会破坏语感，就不要分割。
