答案d. 以具有否定意義的副詞放在句首時,一般採用倒裝句(謂語前置)。這類表示否定意義的詞有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等。

注意:只有當not only… but also連線兩個分句時,才在第一個分句用倒裝結構。如果置於句首的not only… but also僅連線兩個並列詞語,不可用倒裝結構。
  not only you but also i am fond of music.
