Struck
物理打击（struck the ball）、工人罢工（workers struck）、灵感袭来（it struck me that…）、灾害袭击（struck by lightning）。不规则动词，过去式与过去分词同形。

古英语 strīcan 原义“轻擦、划过”，后引申为“猛击”；现代 strike 还保留“擦过、敲响钟”等古义痕迹。
strike 的不规则变化：strike → struck → struck；名词 strike 与 struck 形式独立使用。
新闻里 country struck by earthquake 很常见；职场语境 struck a deal 指“达成协议”。棒球 strike 与动词 strike 拼写相同义不同。
- 固定搭配: “struck by” (被…击中/打动), “struck gold” (发大财), “struck a chord” (引起共鸣)
- 名词: strike, striker
strike 像“一划”，struck 是“已经划/打中了”的短促音 strʌk。
