become

Compared meaning: to change into a new state (verb).

比较义项：变得/变成（动词，表示状态或身份的变化）。

• go

  Go is limited to a small set of fixed negative or dramatic changes (go crazy, go bad, go blind) and cannot be followed by a noun; it sounds vivid and often bad.

  go只用于一小部分固定的、通常带有负面或戏剧性色彩的变化（go crazy发疯、go bad变坏、go blind失明），后面不能接名词，语气比较生动，而且常表示不好的变化。

  The bread has already gone stale since we left it out.

  自从我们把面包放在外面后，它就已经变得不新鲜了。

• get

  Get is the everyday, informal choice for almost any change of state, especially with adjectives, and dominates in casual speech.

  get是口语中表示各种状态变化最常用、最随意的说法，尤其常接形容词，在日常对话中占主导地位。

  It gets dark really early once winter arrives here.

  冬天一到，这里天很早就黑了。

• become 本词

  Become is the neutral, more formal verb that works with both adjectives and nouns, and is common in writing.

  become是中性、较正式的动词，既可以接形容词，也可以接名词表示身份变化，在书面语中很常见。

  After years of hard training, she finally became a professional dancer.

  经过多年刻苦训练，她终于成为了一名职业舞者。

All three mean changing into a new state. Go is limited to a few fixed, often negative changes. Get is the everyday, informal choice for almost any change. Become is neutral, formal, and can take a noun. Not compared: go's 'travel' and get's 'obtain/buy' meanings.

这三个词在“变得/变成”这个义项上意思相近，但用法和语气不同：go常用于固定搭配，多表示变坏或变得极端；get是口语中最常见、最随意的说法；become更中性、正式，还能接名词表示身份变化。这里不比较go的“去、前往”义项，也不比较get的“获得、买到”义项。

Compared meaning: to be right or fitting for someone (verb).

比较义项：适合，相衬（动词）。

• become 本词

  Formal and somewhat old-fashioned; describes something (clothing, color, behavior) as fitting or becoming to a person's character or appearance, often in negative set phrases like 'does not become'; rarely used in casual speech.

  较为正式且略显古雅；用来形容某样事物（服饰、颜色、举止）与人的气质或外表相衬，常见于“does not become”这类否定说法中；口语中很少使用。

  Such rude behavior does not become a gentleman.

  如此粗鲁的举止不符合一位绅士的身份。

• suit

  Common, everyday word for being right, convenient or appropriate for someone; used broadly with clothes, colors, times, schedules, jobs and arrangements; neutral in register.

  常用词，表示对某人而言合适、方便或恰当；可广泛用于衣服、颜色、时间、日程、工作和安排等，语域中性。

  This meeting time doesn't suit me because I have a class then.

  这个开会时间不适合我，因为我那时候有课。

Both words mean being right or fitting for someone. Become is formal and old-fashioned, describing clothes or behavior that suit a person. Suit is the everyday word, used for clothes, colors, times, or jobs being convenient. Not compared: become's common meaning 'turn into'.

这两个词在“适合”这一义项上意思相近，但语域和用法不同：become 较为正式、古雅，多用于服饰、外表或举止是否与人相衬，常见于“does not become”这类固定说法；suit 是日常常用词，可广泛用于衣服、颜色、时间、日程、工作等是否合适或方便。此处不比较 become 的常见义项“变成”（如 become a doctor）。
