例102　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】主语中心语是This trend，谓语动词是began, when引导的定语从句修饰前面的Second World War，在这个定语从句中的主语是several governments，动词是came to，宾语conclusion，后面又加上同位语从句that，而同位语从句的主语是the specific demands，后面加上that引导的定语从句，也就是that a government wants to make of its scientific establishment，动词是被动语态cannot generally be foreseen。

【亮点回放】此句话的亮点在于多重从句的层层相连环，when引导的定语从句里面套上that引导的同位语从句，这个同位语从句里面还有宾语从句，这种从句层层嵌套式是个考研难度大、效果好的经典结构。
