▲你的翻译不准确，句子的意思是：

Why are you blaming them for something they didn't have anything to do with?

你为什么要因为一些与他们无关的事去责备他们呢？

▲分析：句中的 they didn't have anything to do with 是定语从句，修饰 something；blame sb for sth 意思是“因为某事而责备某人”。

▲补充两个短语的用法：

1. have nothing to do with 与……无关

What he says is [has] nothing to do with me. 他说的与我与关。

The book has nothing to do with our lessons. 这本书我们的功课无关。

2. have something to do with 与……有关。如：

His job is something to do with oil. 他的工作和石油有关。

The book has something to do with this subject. 这本书与这个问题有些联系。

The programme’s something to do with the environment. 这个节目的内容和环境有关。

▲英语的反问句：主要用于要求对方肯定或解释所说过的话。这种疑问句往往重复对方的话，或提出特殊疑问，句末用升调。如：

(1)—I’m going to town. 我要进城去。

    —To town? 进城?

    —Yes. 是的。

(2) —Have you borrowed my pen? 你借我的钢笔了吗?

    —Have I borrowed your pen? 借你的钢笔?

(3) —It cost five dollars. 它的价钱是五美元。

    —How much did it cost? 它的价是多少?

    —Five dollars. 五美元。

(4)—Take a look at this. 你看看这个吧。

    —Take a look at what?看什么呀?

下面的句这类否定疑问也有人称之为反问句，但也有人将其归为修辞性疑问句：

Who doesn’t know? 谁不知道? (意即谁都知道) 

Haven’t you got anything better to do? 你难道没有更值得的事可做吗? (意即当然有)
