2018考研英语长难句分析指导（三十一）

.This trend began during the Second World War, when several governments came to the conclusion that the specific demands that a government wants to make of its scientific establishment cannot generally be foreseen in detail.

结构分析：句子主干是This trend began during…, when…引导时间状语从句, 第一个that引导同位语从句，表明conclusion的内容。第二个that引导的是修饰demands的定语从句。

译文：这种趋势始于第二次世界大战期间，当时一些国家的政府得出结论：政府向科研机构提出的具体要求，通常是无法详尽预见的。
