　　[长难句突破]

　　For a while it looked as though the making of semiconductors, which America had invented and which sat at the heart of the new computer age, was going to be the next casualty.

　　主体句式：It looked as though…

　　结构分析：本句的主干中it是主语，looked是系动词，as though引导的从句是表语。表语从句中的主语是The making of semiconductors was going to be the next casualty，主谓之间以and连接两个用which引导的定语从句，用来修饰semiconductors。
