Sense: adjective/1

這四個詞在指涉功能上有關鍵差異: 「this」vs「that」— this 表示近距離(空間、時間或心理上靠近說話者),如 This book in my hand is interesting;that 表示遠距離(遠處或過去),如 That mountain is far away。 「this」vs「it」— this 可引入新資訊或強調特定對象,it 則指代前文已明確提及的已知事物。例如 This is my friend(介紹新人物)與 I met him yesterday; he is nice(it 指已知對象)。 「this」vs「the」— the 僅表示雙方都知道的特定事物(如 the sun),this 則強調當下性與靠近感(如 this weather we are having)。在對話中,選用 this 而非 the 會帶來更強烈的「就在這裡、現在」的語氣。
