  这部电影的结局让影院里的每个人都感到意外。

• close

  "Close" is a formal noun for the end of an event, period, or process, common in set phrases like "the close of trading" or "the close of day"; it sounds odd for a story's ending.

  “close”是正式名词，指某个事件、时段或过程的结束，常见于“the close of trading”（交易的收盘）或“the close of day”（一天的结束）等固定搭配；用来形容故事的结局会显得很奇怪。

  Trading remained flat until the close of the market.

  交易一直平稳，直到收盘时才有变化。

• conclusion 本词

  "Conclusion" refers to the final part of a speech, essay, or argument that sums up the main point; it belongs to formal or academic writing, not casual stories or events.

  我们终于走到了那条长长徒步小径的尽头。

Ending, close, conclusion, and end all mean the final part of something. Ending suits stories or films. Close is formal, for meetings or trading. Conclusion is the final part of a speech. End is the general, everyday word. Their other senses are not compared.

这四个词都可以表示“结尾、结束”，但语域和搭配不同——ending 多指故事、电影等的结局，close 是正式用词，常用于会议、交易日等场合的“结束”，conclusion 指文章、演讲或论证的结尾部分，end 则是最通用、最常见的说法，几乎可以替代其余三者。这里不比较 close 作动词“关闭”（如 close the door）、end 作动词“结束”以及 conclusion 表示“（推理得出的）结论”的用法。

• closing

  Refers to the specific act or scheduled time of ending something, common in everyday and business settings such as 'closing time' or 'closing ceremony'; often functions almost like a modifier before a noun.

  指结束某事的具体行为或安排好的时间，常见于日常和商务场合，如“closing time”（打烊时间）或“closing ceremony”（闭幕式）；常像修饰语一样放在名词前面。

Close, conclusion, end, and closing all mean the end of something. Close and conclusion are formal words. End is the common word for the last point. Closing names the time of ending. Verb uses of close and end, plus conclusion's 'reasoned result', are not compared.
