bid

Compared meaning: to formally offer a price or proposal (verb).

比较义项：正式提出报价或投标（尤指为合同、项目等正式提交价格或方案）（动词）。

• tender

  Formal, often British business term for officially submitting an offer or proposal, typically for a contract or project, without necessarily naming a specific price; used by organizations, not individuals at auctions.

  tender是较为正式的词，常见于英式商业英语，指企业或机构正式提交一份报价或方案，通常针对合同或项目，不一定注明具体价格；用于机构而非个人在拍卖中的场合。

  Several construction firms tendered for the government's new road-building contract.

  好几家建筑公司为政府新的道路建设合同正式投了标。

• bid 本词

  Means to name a specific price you are willing to pay or accept, most often at an auction or in a competitive process; used by individuals as well as companies, common in everyday and American English.

  bid专指说出你愿意支付或接受的具体价格，最常用于拍卖或竞标场合；个人和公司都可使用，在日常英语和美式英语中都很常见。

  She raised her hand and bid five hundred dollars for the antique vase.

  她举起手，为那件古董花瓶出价五百美元。

Both words mean to formally offer a price or proposal. Tender is formal, often British business English, for submitting a proposal by an organization, without an exact price. Bid means naming a specific price, often at an auction, by an individual. Other meanings excluded.

这两个词都可表示“正式提出报价／投标”，但语域和使用场合不同：tender更正式，常见于英式商业英语中企业为合同投标；bid更常见于拍卖或日常竞标场合，强调当场报出具体价格。这里不比较tender作形容词表示“嫩的、温柔的”（如tender chicken）以及bid在纸牌游戏中“叫牌”或“向某人道别（bid someone farewell）”等其他意思。
