have something to do with 这个比较常用。
使用的时候，如果是with后面的对象是比较抽象或是一个概念性的、笼统性的事物的时候用have something to do with ；如果是简单对象一般使用have to do with。
举例一：
Hmm.might have something to do with all the vomit.
嗯，也许要处理所有的呕吐物。
举例二：
What does Yang Jisheng have to do with business?
用法：
have用作助动词时,可与动词的过去分词或“been+现在分词”连用,构成动词的各种完成时态。
have的过去分词had还可与主语倒置,构成虚拟条件状语从句。
have (got) to作“不得不”解,强调客观上的必要,或由环境、习惯、协约等迫使而不得不做某事。have (got) to用于疑问句或否定句时,一般要借助do,在英式英语也可不借助do。
- "have to do with" 是一个常见的短语，表示与某个主题、问题或情况有关。它强调的是存在一种关联或联系。例如：His success has to do with hard work and determination.（他的成功与努力工作和决心有关。）在这个例子中，"have to do with" 指的是成功与努力工作和决心之间的联系。
- "have something to do with" 强调的是某人或某物与特定事物之间的关系或涉及的程度。它指的是某人或某物在某个情况中的参与或影响。例如：She had something to do with the decision-making process.（她参与了决策过程。）这里，"have something to do with" 表示她在决策过程中有一定的涉及或影响。
总体而言，"have to do with" 更加通用，用于描述广泛的相关性；而 "have something to do with" 则更加具体，强调某人或某物在特定事情中的参与或关联程度。然而，具体的使用还与上下文和语境有关。
比较常用的是“have something to do with”
eg.
