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.
gre阅读长难句的并不是一天两天就能解决的，需要考生的坚持和日常的积累。
They are called virtual particles in order to distinguish them from real particles，whose lifetimes are not constrained in the same way，and which can be detected.
它们被称为“虚粒子”(virtual particle)，以便与实粒子(real particle)区分开来，而实粒子则不会以这种方式受到制约，并且其存在可得以测定。
难句类型：复杂修饰、插入语
解释：本句的怪异在于：real particles后面跟着两个定语从句，都是同时修饰real particles的，而且两个从句之间不用逗号隔开，却又加上and连接，令人一眼看上去极不习惯。

Open acknowledgement of the existence of women‘s oppression was too radical for the United Stated in the fifties， and Beauvoir’s conclusion ， that change in women‘s economic condition ， though insufficient by itself ， “remains the basic factor ” in improving women’s situation ， was particularly unacceptable . (4+)
公开对妇女压迫的存在的承认对于50年代的美国而言有些过分激进，而且B的结论，即妇女经济状况的变化，经管它本身不是一个充分的因素，但是“仍然是提高妇女地位的根本因素”的观点，尤其无法令人接受。
难句类型：复杂修饰、插入语
解释：本句是由and所连接的两个分句，前一个分句的主语虽然有一些修饰成分，但整体而言还算好读;后面的分句中的修饰成分就比较难读;主语Beauvoir‘s conclusion后面被加上了同位语从句that change in…，而且在从句的主语和谓语之间还加了一个插入语;我们好不容易把同位语从句中的成分补齐，后面又看到系表结构was particularly unacceptable的时候，想不起来主语是誰，不禁心中茫然;如果是没有练习过难句的人，也只好黯然神伤。
