・We hardly saw each other after the graduation.（倒裝前）

→ Hardly did we see each other after the graduation. （倒裝後）

畢業後我們幾乎沒見到對方。

解析:

Little _did__we___know___ why the new manager decided to fire Paul and hire John.

中翻英:我們幾乎不知道經理為什麼決定解僱保羅並僱用約翰

解析:

否定副詞至於句首，需要用倒裝句，若原具有助動詞，倒裝句結構為

否定副詞+助動詞+主詞+原行動詞

就要自己加入do/does/did 作為助動詞喔！用刪去法(A)(C)保留，(因為倒裝所以we放前面)
