白勇语法书之平行结构题目请教 Temporary_employment agencies benefit not only from the increasing demand for clerical workers but also [the higher profits made when highly paid professionals are placed,requests for whom] have increased in the recent wave of corporate takeovers. C)from the requests for highly paid professions,who make higher profits for the agencies when placed and whose requests. D)from highly paid professions,whose placement makes higher profits for the agencies and whose requests 白大侠对这两个选项的解释是两个定语从句并列,共同修饰名词PROFESSIONALS,WHOSE REQUESTS HAVE INCREASED 表示专业人员的自身需求在增加,而不是对专业人员的需求在增加,逻辑意思不合理。 我对于“专业人员的自身需求在增加,而不是对专业人员的需求在增加”不明白,可能是我还没有看他的逻辑表达这一章吧,请XDJM帮忙解释一下,小妹这厢有礼了!
