● 題目：

　　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.(劍5, Test 2 passage 1)

　　● 分析：

　　本句為并列句，“Electrical manufacturers seized on its insulating properties”和“consumers everywhere relished its dazzling array of shades”并列，由and連接;“delighted that they were now, at last, no longer restricted to the wood tones and drab browns of the pre-plastic era”為過去分詞短語做伴隨狀語;其中“that they were now, at last, no longer restricted to the wood tones and drab browns of the pre-plastic era”為that引導的賓語從句(其前省掉了介詞at)。
