get

Compared meaning: to come to have something (verb).

比较义项：得到、获得某物（动词）。

• get 本词

  "Get" is the general, informal, everyday word for acquiring something in any way — buying, fetching, receiving, or achieving; it works in almost any context and is the default choice in casual speech.

  “Get”是获得某物最通用、最口语化的说法，无论是购买、拿取、收到还是达成目标都可以用它；它几乎适用于任何语境，是日常口语中的默认用词。

  I forgot to get bread before the shop closed for the day.

  我忘了在商店打烊前买到一些面包。

• obtain

  "Obtain" is formal and suggests effort, application, or an official process is needed, often paired with words like "permit", "licence", or "permission"; it is rarely used in casual speech.

  “Obtain”比较正式，通常暗示需要付出努力或经过某种（官方）手续，常与“许可证”“执照”“许可”等词搭配；不用于随意的口语场合。

  You must obtain a permit before starting any construction work.

  在开始任何建筑施工之前，你必须获得许可证。

• receive

  "Receive" implies something is given or sent to you by someone else — you are the passive recipient, not the one who seeks or works for it, as with a letter, gift, or package.

  “Receive”强调某物是别人给予或寄送给你的，你是被动的接收者，而不是主动寻求或努力获得的一方，例如收到一封信、一份礼物或一个包裹。

  She was delighted to receive a handwritten letter from her old friend.

  收到老朋友寄来的一封手写信，她非常开心。

All three mean coming to have something. Get is the most common, everyday, informal word. Obtain is more formal, often implying effort or an official process. Receive stresses passively being given or sent something by someone else. Not compared: get's other meanings, 'become' and 'arrive'.

这三个词在“得到某物”这个意义上很接近，但语气和方式不同：get最通用、最口语化；obtain更正式，常暗示需要努力或经过手续；receive强调被动地收到别人给予或寄来的东西。这里不比较get的其他常见用法，例如“变成”（get angry）或“到达”（get home）。

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 本词

  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

  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。
