【结构分析】句子的主干是"It is no use inviting ...to work or worry about...".
"who has been working or worrying about serious things for six days"是定语从句修饰“the professional or business man”。

【参考译文】在办公室或工厂里长时间的工作，不仅带给他们维持生计的金钱，还带给他们一种渴求娱乐的强烈欲望，哪怕这种娱乐消遣是以最简单，最淳朴的方式进行的。
【结构分析】句子的主干是"The long hours...bring...as..."，后面的“not only...but....”修饰"reward".
