為什麼 "fighting" 這會是 gerund?
proactive1 definition
proactive (prō ak′tiv)
adjective
assuming an active, rather than passive, role in doing, accomplishing, etc.; taking the initiative a proactive approach to fighting drug abuse.
"to" 之後不是跟 infinitive 嗎 ? or 是否因前面 taking 而所以 coincidence 用 fighting, pls explain.
Thanks!
