其结构是A has sth to do with B,意思是A与B有关,若无关,则是A has nothing to do with B,
例句：This has a lot/much/something to do with me.表示有关
It has little/nothing to do with me. 表示无关
have/has 后面不一定要用something或nothing,只要是表示多或少的名词如：a lot ,much ,little即可．
在口语中,还可以用
it got sth to do with 或 it's got sth to do with
疑问句则用：what's it got to do with 或what does it got to do with,后面这种比较少用,在语法上也讲不通．
