wear的用法大全

wear是英语中常用的动词，含义丰富，用法灵活，涵盖穿着、状态、磨损等多方面。以下从动词和名词两方面梳理其主要用法。

作为及物动词，wear最核心的含义是“穿着；戴着”，后接衣物、饰品等具体物品，状态而非动作。例如：She often wears a black coat in winter.她冬天常穿黑色外套；He wears glasses to read.他戴眼镜看书。此时常用一般现在时表习惯，进行时表当前状态，如They are wearing traditional costumes today.他们今天穿着传统服饰。

wear也可表示“留发、须等”，后接hair、beard等名词。例如：He wears short hair now.他现在留短发；My grandfather wears a gray beard.我祖父留着灰胡子。

“磨损；用旧”是wear的另一重要用法，此时主语多为物，主动形式常表被动意义。例如：The old chair has worn smooth.旧椅子磨得光滑了；This fabric wears well.这种布料耐穿。若需明确动作执行者，可加by，如The shoes were worn thin by daily walking.鞋子因日常行走磨薄了。

表达“面露表情”时，wear后接smile、frown、look等词，描述面部状态。例如：She wore a worried look when she heard the news.听到消息时，她面露担忧；The child wore a big smile after getting the toy.孩子拿到玩具后笑得灿烂。

固定短语是wear用法的重点。wear out意为“穿坏；耗尽”，如These shoes will wear out soon.这双鞋很快会穿坏；The long walk wore me out.长途步行让我筋疲力尽。wear off指“逐渐消失”，如The pain wore off after taking medicine.服药后疼痛渐渐消失。wear on表示“时间流逝”，如As the night wore on, we felt more tired.夜渐深，我们越发疲惫。wear down意为“磨损；使疲惫”，如The steps have been worn down by years of use.台阶因多年使用被磨平了；Constant noise wore her down.持续的噪音让她疲惫不堪。

作为名词，wear可指“磨损；耐用性”，如The carpet shows signs of wear.地毯有磨损的痕迹；This material has good wear.这种材料耐用。也可指“流行的服饰”，如the latest summer wear最新夏装，但此用法较少见。

综上，wear的用法围绕“状态、磨损、表情”等核心，结合固定短语后适用场景更广，需通过具体语境灵活掌握。
