　　63.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 1880s created a new class of dead-end jobs，thenceforth considered womens work.

　　十九世纪八十年代，产生了新的一类没前途的职业，这并不是因为办公室技术发生了改变，而是由于秘书工作在此之前被视作是初起步的经理们的一种习见训练与行政工作的分离。自此以后，这类没前途的职业便被视作是女人的工作。

　　64.The increase in the numbers of married women employed outside the home in the twentieth　　century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers，previously，in many cases，the only women employers would hire.

　　66.But the plays complex view of Black self-esteem and human solidarity as compatible is no more contradictory than Du Bois famous，well-considered ideal of ethnic self-awareness　　coexisting with human unity，or Fanons emphasis on an ideal internationalism that also accommodates national identities and roles.

　　但该剧有关黑人自尊可与人类团结相融合这一复杂观点，丝毫都不比杜波伊斯的理想或法侬的强调来得更为矛盾：杜波伊斯提出的著名的、深思熟虑的理想是，民族的自觉可以和人类大同共存;法侬则对理想的国际主义进行了强调，而这一理想的国际主义同样也能兼容民族身份与角色。
