　　● 题目：

　　But a written form is essential for this, so the mere possibility of revival has led many speakers of endangered languages to develop systems of writing where none existed before. (test2 passage 1)

　　● 分析：

　　本句中用so(连词)连接“a written form is essential for this”和“the mere possibility of revival has led many speakers of endangered languages to develop systems of writing where none existed before”两个简单句成为一个并列句;“where none existed before”为where引导的地点状语从句。
