　　● 分析：

　　本句的主句为“the subject merges his unique personality and personal and moral code with that of larger institutional structures”;“surrendering individual properties like loyalty, self-sacrifice and discipline to the service of malevolent systems of authority.”为现在分词短语作状语，做主句的伴随状语。

　　● 分析：

　　本句为并列句，“One form of pollution does appear to be a phenomenon”和“but its total impact is unlikely to pose a devastating problem”并列，由but连接;破折号中内容为解释说明部分，解释One form of pollution;“that is going to extend well into our future”为定语从句，做a phenomenon的定语，关系词为that。

　　● 题目：

　　That would matter less if people applied the same degree of skepticism to environmental lobbying as they do to lobby groups in other fields.(剑5, Test 1 passage 3)
