請問各位: The door isn't locked! Why didn't Franco lock it before he left? Why ask me ? How am I supposed to know why [he didn't lock] it ? 第二句的why整句不是名詞子句嗎? 主詞放在動詞&助動詞前 而文法書上(AZAR P244 12-2chart)寫說do does 用於疑問句，但不用於名詞子句， 請問各位為什麼在這句的名詞子句中用do does呢?

如果你說的do does是 he [didn't] lock it的話do does[不用於]名詞子句，會不會是因為是肯定句why那句應該是因為didn't是否定句所以要保留
