标志： It was {not the change in office technology，but rather the separation ［of secretarial work，（previously seen as an apprenticeship for beginning managers,) /from administrative work］} that in the 1880's created a new class of “dead-end” jobs，（thenceforth considered “women's work”.)

译文： {倒不是 办公室技术的进步，而是 ［（原来被视为见习经理的职位的 ）秘书工作/与 管理工作的/］ 分离 ，}在19世纪80年代产生了一种新的“死胡同”工作，（这种工作从那以后就被认为是“妇女的工作”）。

解释： 这句话的结构是It was something that...，It是形式主语，其真正的内容是was之后、that以前的something的内容。本句的“something”结构复杂、长度惊人，并且包含了一个较长的插入语，把固定搭配separation from 分开，造成了极大的阅读困难。其实这个句子说得简单就是It was the separation of secretarial work from administrative work that created a new class of jobs。
