And interest groups ranging from postal unions to greeting-card makers exert self-interested pressure on the USPS’s ultimate overseer—Congress—insisting that whatever else happens to the Postal Service, aspects of the status quo they depend on get protected. (2018年 英语一 Text4)
【难点分析】本句为复合句。句子的主语是interest groups,谓语是exert,宾语是self-interested pressure,主语和谓语之间的ranging from ... makers是作后置定语,修饰interest groups,破折号内的Congress是状语中the USPS’s ultimate overseer的同位语,insisting that ... protected是现在分词作伴随状语,状语中包含一个宾语从句whatever else ... protected。
