- 1被動應對的、事後反應的（proactive 的反義）；（化學）易起反應的
Responding to something after it happens, instead of planning ahead or acting first — a 'reactive' approach to problems means you deal with them only once they show up, which is often seen as less ideal than being 'proactive' (planning ahead). In chemistry, 'reactive' describes a substance that easily reacts with other substances, sometimes in a strong or dangerous way, like a 'highly reactive chemical.'

組成'React' + '-ive' (an adjective ending meaning 'tending to').
