各位同学，今天我们将继续进行长难句的学习，我们今天要分析的内容选自2018年英语一试题，希望通过今天的学习大家可以有所收获。
1. （2018英语一Text 4）Fundamentally, the USPS is in a historic squeeze between technological change that has permanently decreased demand for its bread-and-butter product, first-class mail, and a regulatory structure that denies management the flexibility to adjust its operations to the new reality.
结构分析：本句较长，句子的主干为 the USPS is in a historic squeeze，句子后半部分“between…reality”为介词短语作后置定语，修饰主干的historic squeeze。整个后置定语中包含两个定语从句，定语从句1“that has permanently decreased demand for its bread-and-butter product, first-class mail”修饰的先行词为technological change，定语从句2“that denies management the flexibility to adjust its operations to the new reality”修饰的先行词为a regulatory structure。
词汇积累：squeeze 挤压；permanently 永久地；bread-and-butter 基本的；flexibility 灵活性
句子翻译：根本上说，美国邮政处于科技变革和管理结构的历史挤压之中。科技变革永久降低了对其基本产品——一级邮件的需求，管理结构否认了调整操作以适应新现实的管理灵活性。
2. （2018英语一Text 4）This is why repeated attempts at reform legislation have failed in recent years, leaving the Postal Service unable to pay its bills except by deferring vital modernization.
结构分析：本句的主干为“This is +表语从句”，表语从句由why引导至recent years结束，表语从句谓语动词为have failed。主干后为v-ing结构作状语。
词汇积累：attempt 尝试；legislation 改革；defer 推迟；modernization 现代化
句子翻译：这就是为什么几年来立法改革多次失败的原因，使得邮政服务无法支付账单，除非推迟重要的现代化。
3. （2018英语一Text 2）A 2014 survey conducted in Australia, Britain, and the United States by the University of Wisconsin-Madison found that young people’s reliance on social media led to greater political engagement.
结构分析：本句的主干为A 2014 survey found that young people’s reliance on social media led to greater political engagement，主干的宾语为that引导的宾语从句，主干的谓语动词为found，宾语从句的谓语动词为led to。句中的“conducted in Australia, Britain, and the United States by the University of Wisconsin-Madison”为后置定语，修饰survey。
词汇积累：conduct 进行；engagement 参与；reliance 依靠
句子翻译：2014年威斯康星麦迪逊大学在澳大利亚、英国和美国进行的一项调查发现，年轻人对社交媒体的依赖会导致其更多参与到政治中。
