On which是什麼意思

"On which" 是英文中一個常用的連接詞,用來引導一個從句,修飾或提供關於前面提到的名詞或名詞短語的資訊。這個詞組通常用於正式的書面語中,尤其是在描述或討論某個特定的主題、物品、事件或概念時。

在句子中,"on which" 通常用來取代 "about which"、"of which" 或 "as to which",取決於從句的內容和它與主句的主詞的關係。以下是一些例子:

  1. "The book, on which you are so enthusiastic, is finally available." (這裡 "on which" 取代 "about which",因為從句修飾的是 "book",而 "enthusiastic" 這個形容詞是關於書的。)

  2. "The committee has reached a decision on which all members agree." (這裡 "on which" 取代 "as to which",因為從句修飾的是 "decision",而 "all members agree" 是關於這個決定的。)

  3. "The table, on which we had our dinner, was beautifully set." (這裡 "on which" 取代 "of which",因為從句修飾的是 "table",而 "we had our dinner" 是關於這個桌子的用途。)

請注意,"on which" 通常用於描述某個特定的方面或特性,而不是用於空間或位置的關係。如果是指示空間或位置,通常會使用 "at which"、"in which" 或 "where"。
