💡专业提示

区分‘impact’与‘effect’

‘Impact’强调‘冲击力’或‘深远影响’,常用于描述突发或强烈的作用;而‘effect’更侧重‘结果’或‘效果’。例如:‘The policy had a strong impact on the market’(政策对市场产生了强烈冲击)vs. ‘The policy had a positive effect on the market’(政策对市场产生了积极效果)。

⚡黄金法则

动词用法的时态与语态

动词‘impact’常用于被动语态(e.g. The community was impacted by the flood.)或现在分词(e.g. The impacting force caused structural damage.)。在正式文体中,过去式和过去分词均为‘impacted’。

📖词源

源自拉丁语‘impactus’,由‘in-’(进入)+‘pangere’(击打)构成,原指‘猛烈撞击’。17世纪引申为‘强烈影响’的抽象意义。

📝用法说明

1. 作动词时常与介词'on'连用(e.g. impact on sth.)。2. 在正式文体中可用作名词(e.g. the impact of the decision)。3. 现代用法中,动词‘impact’常用于商业或科技语境(e.g. The new app will impact user experience)。
