● 题目：

　　Electrical manufacturers seized on its insulating properties, and consumers everywhere relished its dazzling array of shades, delighted that they were now, at last, no longer restricted to the wood tones and drab browns of the pre-plastic era.(剑5, Test 2 passage 1)

　　● 分析：

　　本句为并列句，“Electrical manufacturers seized on its insulating properties”和“consumers everywhere relished its dazzling array of shades”并列，由and连接;“delighted that they were now, at last, no longer restricted to the wood tones and drab browns of the pre-plastic era”为过去分词短语做伴随状语;其中“that they were now, at last, no longer restricted to the wood tones and drab browns of the pre-plastic era”为that引导的宾语从句(其前省掉了介词at)。
