　　● 题目：

　　The fact that Johnson had taken on the Academies of Europe and matched them (everyone knew that forty French academics had taken forty years to produce the first French national dictionary) was cause for much English celebration.(剑5, Test 1 passage 1)

　　● 分析：

　　本句的主句为“The fact was cause for much English celebration”;“that Johnson had taken on the Academies of Europe and matched them”为that引导的同位语从句，做The fact的同位语;括号中部分起到解释说明的作用。
