Which of the following most probably provides an appropriate analogy from human morphology for the "details" versus "constraints" distinction made in the passage in relation to human behavior?
解析:尽管我们很熟悉 the role of something 的这种表达,但本句中 the role of 被作者胜利很活。 首先, 在 role 后面有一个省略了引导词 that 的定语从句(因为 role 在从句中作 ascribe 的宾语),这样就把 role 和系动词 is 隔得很远。其次, but 前面的句子的主要结构 The role is not of doing something 其实是 The role is not the role of doing something 的省略形式,因为后面的 the role 与前面的完全重复,如果不把它省略掉,谁看到都要觉得啰嗦。因为同样的道理, but 之后的 one of imposing constraints 实际上是 is one role of imposing constraints 的省略形式。
