(English) against點用?

"against" 係 preposition , 可解作 "反對的", "相反的", "逆著的"。
Preposition 通常是和 object 一同用作一個 phrase。
"acting in haste" 是一個 object。"against acting in haste" 是一個 adverbial phrase, 用於描述 the verb "advised"。
"We advised him against acting in haste." = "we advised him to do the opposite of acting in haste" = "we advised him not to act in haste".
