Even the “radical” critiques of this mainstream research model，such as the critique developed in Divided Society，attach the issue of ethnic assimilation too mechanically to factors of economic and social mobility and are thus unable to illuminate the cultural subordination of Puerto Ricans as a colonial minority. (4+)
即使是对这一主流研究模型的“激进”批评，诸如《分裂的社会》(Divided Society)一书中所提出的那种批判，亦将少数民族同化问题过分机构地与经济和社会移动性的因素联系起来，因此无从阐明波多黎各人作为一个殖民地少数民族的文化从属关系。
难句类型：复杂修饰、插入语、省略、抽象词
解释：本句实际上是由and连接的两个句子，阅读的一个难度在于，and之后省略了they(此处指前面的主语the radical critiques，)而are thus able to 又与前面离得太远，使读者难以找到主语。
另外，句中的固定搭配attach A to B和illuminate C as D当中的A、B、C，全部既长又抽象，理解起来较为困难。
意群训练：Even the “radical” critiques of this mainstream research model，such as the critique developed in Divided Society，attach the issue of ethnic assimilation too mechanically to factors of economic and social mobility and are thus unable to illuminate the cultural subordination of Puerto Ricans as a colonial minority.
