结构:`trade in sth`
例子:

They’ve been trading in antiques for over 20 years.(他们经营古董已有20多年。)
偶尔用于日常场景中“用A换B”,但不如前两种常见。

trade in vs trade with:
`trade in` 侧重“交换/经营某物”(宾语是商品);
`trade with` 侧重“和某人/某地做交易”(宾语是人或地点)。
例子:We trade in used furniture and trade with local retailers.(我们经营二手家具,并与当地零售商合作。)
`trade in`的核心是“通过交换旧物或经营商品实现交易”,最常用的场景是“以旧换新”,其次是“经营特定商品”。记住结构`trade in sth (for sth)`,搭配具体例子更容易掌握!
