122【讲解】静姐考研英语每日一句 I 2018英一T4-01

原句：

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.

两个that均引导定语从句

生词：

bread-and-butter product n. 基本产品，主要产品

deny sb. sth. 拒绝某人做某事，使某人无法做某事

adjust…to… 调整…以适应…

翻译：

根本原因在于，USPS正处于“历史性挤压”中：一面是技术变革导致对其核心产品（普通邮件）的需求永久性降低；一面是监管体系使其管理层无法灵活调整业务以适应新现实。
