have to do with和have something to do with有什么区别

都是： 与…有关；干；相干
have something to do with 这个比较常用

What does it have to do with you? 与你何干?

Does his visit have something to do with the meeting tomorrow? " 他这次来是不是跟明天的会议有关? ”

Answer 2

为您解答
do是及物动词，所以have后面都是应该有东西的，前者如果你看到have to do with...，那个东西有可能是提到了前面，例如;
What does it have to do with the murder?
这个其实就是have sth to do with的疑问型形式。

还有一种情况是，have to是不得不，do with....用。。。来做。这里do不及物。

There's no way out, I have to do with it.
没别的办法了，我不得不用它了。

追问

什么时候用have to do with，什么时候要something

追答

和。。。有关时，用have....to do with,比如
have sth to do with
have nothing/little/a lot to do with...

表示不得不用。。。用have to do with sth
