答案解析：
1.Before→After。根据前文含义，可知妇女是在经过了长期而艰苦的斗争之后方才获得了和男性同样的教育机会。因此此处应该改为After。
2.different→same。理由同上。
3.down→up。前文已说人们赚钱越来越多，因此此处应该是收入增加而不是减少。
4.Nevertheless→Therefore/Consequently。由上下文可至此处应该为因果关系而不是转折关系，即正因为人们的薪水增长了，对于食物与衣物的需求减少，而对医疗服务、旅游以及教育的需要增加了，所以在这些服务行业可以找到更多的工作机会。
5.them→it。本句中without them指的是没有几门语言的知识，此处them错指a knowledge of several languages，然而knowledge是主语的中心词，所以要把them改为it。
6.present→absent。根据常识可知，该句应该是“如果他因为生病而缺席，当他回来时通常就会失去工作”，present不符合逻辑。
