最终无果----既成事实无法改变-----真是很无奈呀
"At the end of the day" is an idiomatic expression that means ultimately or in the final analysis. It is often used to convey that, after all is said and done, a particular fact or responsibility remains unchanged. Just like at the end of a day, regardless of what happened, the ultimate result is what it is.
"At the end of the day" 是一个习语，意思是在最终、最后的分析中。它通常用来表达无论经过多少讨论或辩论，最终仍然无法改变某个事实或责任的观点。就像一天结束时，无论发生了什么，最终的结果是什么一样。
“At the end of the day, it's his responsibility, and there is nothing you can do.”整个这句话可以理解为“说到底，这是他的责任，你无能为力。”
