以when or where開始的副詞子句，是不能修飾名詞的。👀👻
1. Wrong: "Metro is the church where they go."
(The adverbial clause "where they go" cannot modify a noun such as "church.")
--> Right: "Metro is the church they attend."
2. Wrong: "This is the time when all good men should serve their country."
(The adverbial clause "when all good men should serve their country" cannot modify the noun "time.")
--> Right: "This is the time for all good men to serve their country."
Right: "God is near us when we pray to him."
Right: "When we fail to pray, we cut ourselves off from the greatest source of power in the universe."
其實也是想當然爾，副詞子句當然是修飾「動詞、形容詞或副詞」嘛！但是在實際使用上，卻很可能不察而拿來形容「名詞」了。
