考研英语长难句解析：
第1题：
【分析】复合句。本句的主干是 They would try todecide...。decide 后跟两个并列的宾语从句，分别由 what和 how much 引导。
【译文】它们会试图判定人类智力的用途，而不仅仅是人类有多少智慧。
第2题：
【分析】复合句。主句主干为 The idea is one of those hypotheses。 第一个 that 引导同位语从句补充说明 idea，第二个 that 引导定语从句修饰 hypotheses。
【译文】有一种观点认为，某些民族的智商可能要高于其他民族，这种观点是一种不敢冠之以名的假设。
【点拨】dare not speak its name 为一个固定结构，意为"不敢说出名"、"不敢冠之以名"、"无法说出口"。
第3题：
【分析】多重复合句。主句主干是 He helped popularizethe idea。that...infections 为 idea 的同位语从句，其中not previously...cause 作 diseases 的后置定语;which 引导的非限定性定语从句修饰 the idea;when引导时间状语从句，其中代词 it 也指代 the idea。

第4题：
【分析】多重复合句。主句主干为 he is publishing a paper。 which 引导定语从句修饰 paper;该从句中又包含 not only...but also...连接的并列句。在 not only分句中，that 引导宾语从句，作 suggest 的宾语;在 but 分句中 that 引导定语从句，修饰 process。
