• expand

  The everyday choice; normally used as 'expand on/upon' a point, common in speech and writing across all registers.

  日常最常用的说法，通常搭配 on/upon，用来对某个观点做进一步说明，口语和书面语中都很常见。

  The teacher asked him to expand on his answer with a specific example.

  老师让他用一个具体的例子来详细说明自己的答案。

• amplify 本词

  A formal, less common alternative; typically used in writing to add detail, evidence or emphasis to a statement or argument, rarely used in casual speech.

  较正式、不常用的说法，通常用于书面语中，通过补充细节、证据或强调来充实某个陈述或论点，很少用于日常口语。

  The witness was asked to amplify her earlier statement with more specific dates.

  证人被要求用更具体的日期来补充说明她之前的陈述。

Expand and amplify both mean to explain a point in more detail. Expand is the everyday word, usually said as 'expand on' something. Amplify is more formal, often adding evidence. This does not compare expand as 'grow a business', or amplify as 'make sound louder'.

这两个词在“详细说明某个观点”这个意义上相近，但 expand 更口语化、更常用，amplify 更正式、多见于书面语，且常带有补充证据或强调的意味。这里不比较 expand 的“扩大，扩展（业务、规模等）”，也不比较 amplify 的“放大（声音、信号等）”。
