“have…to do with”是英语中表示“关联、联系”的核心短语，核心含义是“与…有关；和…有联系”。它通过调整中间的修饰词（如something/nothing/much等），可以精准表达“关联程度”的差异。
“have…to do with”本质上是“与…有（某种）关系”，其中“…”的部分用来描述“关系的性质/程度”。
该短语的关键是中间的限定词，常见搭配有以下几类：
have something to do with：与…有关（泛泛的“有关系”）
例：The accident has something to do with bad weather.（这起事故和恶劣天气有关。）
have much/a lot to do with：与…有很大关系（强调“关联度高”）
例：Her happiness has a lot to do with her supportive family.（她的幸福和支持她的家人有很大关系。）
have nothing to do with：与…完全无关（最常用的否定表达）
例：I swear I have nothing to do with the missing money.（我发誓我和丢失的钱毫无关系。）
have little to do with：与…几乎无关（语气比nothing弱，表“关联极小”）
例：His decision has little to do with logic—it’s all emotion.（他的决定几乎和逻辑无关——全是情绪使然。）
疑问句中常用anything代替something，表达“是否有关”：
Does this project have anything to do with your previous work?（这个项目和你之前的工作有关吗？）
I wonder if the delay has anything to do with the traffic jam.（我想知道延误是否和堵车有关。）
后面接名词、代词或从句（从句需用what/that等引导）：
例：The problem has to do with what we learned last week.（这个问题和我们上周学的内容有关。）
主语通常是“事物/事件”，但也可指人（强调“某人与某事有关联”）：
例：He has a lot to do with organizing the party.（他和组织派对有很大关系。）
