常见错误

❌ 错误:He made an excursus to explain the problem.
✓ 正确:He included an excursus to explain the problem.

'make an excursus' 不自然,excursus 通常指书面补充内容,应用 'include/add/write an excursus'。

❌ 错误:This is an excursus of the main topic.
✓ 正确:This is an excursus on the main topic.

表示'关于...的附记'应用介词 'on' 而非 'of','excursus on something' 是标准搭配。

❌ 错误:I will give an excursus in the meeting.
✓ 正确:I will include an excursus in the report.

excursus 多用于书面文本,会议等口头场合应用 'aside' 或 'digression',且搭配 'give' 不典型。

近义词辨析

appendix

appendix 通常指书籍末尾的独立补充部分,内容较完整;excursus 更侧重正文中的离题讨论或穿插的补充说明,可能更简短。

The book has an appendix with statistical data (正式补充章节) vs. The chapter contains an excursus on related theories (文中离题说明)。

digression

digression 强调偏离主题的讨论,常用于口语或非正式写作;excursus 更正式、结构化,常指有意添加的学术性补充。

His speech was full of digressions (随意离题) vs. The thesis includes an excursus on methodology (精心安排的补充论述)。

footnote

footnote 是页面底部的注释,通常很简短;excursus 可以是较长的段落甚至独立章节,提供更深入的扩展说明。

See footnote 5 for the source (简短注释) vs. Read the excursus for detailed analysis (详细附记)。
