Scientific publishers routinely report profit margins approaching 40% on their operations, at a time when the rest of the publishing industry is in an existential crisis. (2020年英语一阅读理解text2)

结构划分：① Scientific publishers routinely report profit margins

② approaching 40% on their operations,

③ at a time

④ when the rest of the publishing industry is in an existential crisis.

重点词汇：

routinely adv. 例行公事地;惯常地;常规地

approach v. 接近

profit margin 利润

existential adj. 人类存在的

语法分析：本句主干为：Scientific publishers routinely report profit margins, 意思是：科技出版商例行报告他们的利润;后面接着的approaching 40% on their operations为V-ing短语作后置定语，修饰前面的profit margins，译为运营的利润接近40%。at a time作时间状语，而后接的when从句，因为前面是表示“时间”的名词“time”，所以是定语从句，修饰time;该定语从句为主系表结构，主语是 the rest of the publishing industry，系动词是is，表语为介词短语in an existential crisis。

参考译文：当出版行业其他部分正处于危机中时，科技出版商例行地报告他们的运营利润接近40%。
