常见错误

❌ 错误:We will talk about the subtopic of the meeting.
✓ 正确:We will talk about a subtopic in the meeting.

错误在于使用了 'of the meeting',这可能导致歧义。正确用法是 'in the meeting',表示在会议中讨论某个副主题,更符合英语习惯。

❌ 错误:This is a small topic under the main topic.
✓ 正确:This is a subtopic under the main topic.

错误在于用 'small topic' 代替 'subtopic',虽然意思相近,但 'subtopic' 是更标准、专业的术语,特指从属主题,在正式语境中应优先使用。
