The explanations on clauses linked by subordinating conjunctions in Section 2 were a bit simplified. In precise structural analysis, these clauses are actually embedded clauses that play a modifier role within an outer clause. This extra lecture provides a more in-depth and comprehensive explanation/clarification of these clauses and their structural role. I included this after the section on modifiers so that you would have the relevant background knowledge for better understanding.

第2節中，對於「使用附屬連接詞連接的子句」的解釋是被簡化的。以精確的結構分析，它們實際上是被外層子句所包著的子句，並在外層子句中扮演修飾語的角色。這個額外的課堂會對這種子句及其結構作用作出更深入和全面的解說。我把它放在講解修飾語的章節的最後，以確保你有相關的背景知識，能對此有更好的理解。
