• send 本词

  The most general and neutral of the three; not limited to physical mail, it covers emails, packages, or even people, and fits almost any register or method.

  三者中最通用、最中性的词，不限于实物邮寄，可用于电子邮件、包裹甚至派遣人员，几乎适用于任何语域或方式。

  Could you send me the report by email before the meeting starts?

  你能在会议开始前把报告用电子邮件发给我吗？

• mail

  American English word for mailing letters or parcels through the postal system; typically used as 'mail something to someone'; British English prefers 'post' instead.

  美式英语中表示通过邮政系统寄送信件或包裹的常用词，常用“mail something to someone”的结构；英式英语中通常用 post 表达同样的意思。

  I need to mail this letter before the post office closes.

  我得在邮局关门前把这封信寄出去。

All three mean sending by mail, but usage differs. Post is British English; mail is American English, for letters or parcels. Send is the most general word, covering mail, email, or people. Post's 'publish online' sense and send's 'dispatch a person' sense are not compared.

这三个词在这里都表示“寄送”，但适用的地域和范围不同：post 是英式英语常用词，mail 是美式英语常用词，两者通常只指通过邮政系统寄送实物（信件、包裹）；send 是三者中最通用、最中性的词，既可以指邮寄，也可以指电子发送或派遣人员，适用范围更广。这里不比较 post 表示“发布（社交媒体帖子）”或“张贴（公告）”的意思，也不比较 send 表示“派遣（人）”的意思。
