2023年考研英语语法备考长难句语法分析和翻译
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.(2018年英语一Text4)
重点词汇：fundamentally adv. 根本的，从根本上
USPS abbr. 美国邮政署(United States Postal Service)
squeeze n. 挤压，压榨
permanently adv. 永久地，长期不变地
bread-and-butter adj. 实用的，基本的

断句：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.
语法分析：句首副词Fundamentally作状语;主干为the USPS is in a historic squeeze主系表结构，主语是the USPS，系动词是is，表语是in a historic squeeze;between technological change and a regulatory structure为介词短语作后置定语，修饰squeeze;that has permanently decreased demand for its bread-and-butter product, first-class mail为定语从句，修饰technological change;that denies management the flexibility to adjust its operations to the new reality为定语从句，修饰regulatory structure。
难点分析：此句难点在于含有多个定语从句，导致句子变长，提取出between A and B结构，有利于理清句子结构。
翻译：从根本上，美国邮政署正处于一个历史性的挤压之中，一方面技术变化已经永久地降低了其基本产品和一类信件的需求，另一方面管理结构拒绝给予管理层灵活性，来让运营适用于新的现实。
