alternatively

Compared meaning: showing another way or option (adverb).

比较义项：用另一种方式代替，或提出另一种可能性（副词）。

• instead

  Signals a true substitution — one thing replaces another that is given up; often follows 'instead of + noun/gerund' or stands alone at the start of a sentence; plain, everyday register.

  表示实际的替代关系——用一事物取代被放弃的另一事物；常接在“instead of＋名词／动名词”之后，或单独放在句首；用语平实、日常。

  She didn't want dessert, so she had fruit instead.

  她不想吃甜点，就吃了水果代替。

• alternatively 本词

  Introduces a second option or possibility without implying the first is rejected; more formal, typically follows 'or' when listing choices.

  引出第二种选择或可能性，并不暗示第一种被否定；语气更正式，常跟在“or”之后用于列举选项。

  We could meet at noon, or alternatively, later in the afternoon.

  我们可以中午见面，或者也可以改到下午晚些时候见。

Instead and alternatively both introduce another way of doing something. Instead means a true replacement, where one thing is given up for another, often with 'instead of'. Alternatively is more formal, introducing a second option without rejecting the first, usually after 'or'.

这两个词都用于提出替代做法，容易混淆：instead 强调用一事物取代被放弃的另一事物；alternatively 语气更正式，用于列举另一种可选方案，并不暗示第一种被否定。
