赞同高老师的解答，网友如果搞清楚perform 和accomplish区别就很容易了。

She was fired for not performing the duties outlined in her contract.

参考译文：因为没有履行合同中规定的职责和义务，她被解雇了。

以上句子语法结构分析如下

She【主语】 //was fired【谓语动词】 //for not performing the duties outlined in her contract【原因状语】.

介词短语的语法结构分析如下

for【介词】// not performing【动名词】 // the duties 【宾语】 //outlined in her contract【后置定语】.

【1】perform:主要指执行,履行或者完成困难较大,较复杂的任务和行动。较正式用词。

We're looking for people of all ages who have performed outstanding acts of bravery, kindness or courage.

我们正在寻找那些见义勇为、乐于助人、勇气可嘉的人，年龄不限。

His council had had to perform miracles on a tiny budget.他的委员会不得不以极少的预算去创造奇迹。

Several grafts may be performed at one operation.在一次手术中可能会进行多次植皮。

【2】accomplish：主要指完成/达成某事，尤其是强调一个成功完成过程；也可指依靠努力成功达到一定目的，或取得一定的结果。属于正式用词

If we'd all work together, I think we could accomplish our goal.

只要大家齐心协力，我想我们就能实现目标。

They are skeptical about how much will be accomplished by legislation.他们对于立法成效心存疑虑。

这两个都是对的，但含义有所不同。accomplish 侧重完成，而perform 强调：做。请看剑桥词典释义：accomplish：

请看外刊使用这两种用法的例句：

请网友特别注意最后一个例句中，作者为什么在一句中同时使用用了accomplish 和perform 来修饰the duties, 这种用法足以说明这两个词的含义相同和不同之处。
