be covered

英 /bi ˈkʌvəd/美 /bi ˈkʌvərd/

v. 动词(被动形式)

被覆盖;被覆盖;涉及;足以支付;报道

词义说明

“be covered”是动词“cover”的被动形式,其核心含义围绕“覆盖”展开。本义是物理上的遮盖,如“The ground is covered with snow.”(地面被雪覆盖。)由此引申出抽象含义:1)被包含或涉及,如“This topic is covered in Chapter 3.”(这个话题在第3章中涉及。)2)被保护或保障,如“You are covered by insurance.”(你受保险保障。)3)足以支付,如“The fee is covered by the grant.”(费用由助学金支付。)4)被报道,如“The event was covered by local media.”(该事件被当地媒体报道。)这些义项共享“覆盖”的意象:物理覆盖、范围覆盖、保护覆盖、费用覆盖、信息覆盖。

词源解析

“cover”源自拉丁语“cooperire”,由“co-”(完全)和“operire”(关闭)组成,意为“完全关闭”,后演变为“遮盖”。中古英语时期进入英语。“be covered”是“cover”的被动语态,由“be”动词加过去分词构成。记忆时可抓住“覆盖”的核心意象,联想到“被覆盖”即“被包含、被保护、被支付”等引申义。

适用语境

“be covered”在正式和非正式场合均常见,但语气和含义随场景变化。学术写作中,常用于说明研究范围,如“The theory is covered in the appendix.”(该理论在附录中论述。)商务邮件中,常表示费用或责任已处理,如“The travel expenses are covered by the company.”(差旅费由公司承担。)日常口语中,可表示“没事,我来处理”,如“Don't worry, it's covered.”(别担心,搞定了。)新闻报道中,指事件被报道,如“The scandal was covered by all major newspapers.”(丑闻被各大报纸报道。)法律文本中,表示受法律条款约束或保障,如“This case is covered under the new regulation.”(此案受新法规管辖。)文学作品中的使用较少,但可具象化描述场景。

语法说明

“be covered”是系表结构,后接介词短语(如“with”、“by”)或副词。常见句型:1)be covered with + 物质名词,强调覆盖物,如“The floor is covered with dust.”(地板上满是灰尘。)2)be covered by + 施动者或抽象名词,强调动作执行者或方式,如“The bill is covered by the insurance.”(账单由保险支付。)3)be covered in + 抽象或具体名词,如“The mountain is covered in fog.”(山被雾笼罩。)易错点:混淆“with”和“by”——“with”侧重覆盖物,“by”侧重施动者;另外,“cover”本身可作及物动词,被动形式后不能再直接跟宾语。

相似词辨析

与“be covered”相近的表达有“be filled with”(充满)、“be coated with”(涂层覆盖)、“be wrapped in”(包裹)、“be enclosed”(封闭)。“be filled with”强调填满,内部充实;“be coated with”强调薄层覆盖,如“be coated with chocolate”(涂巧克力);“be wrapped in”强调包裹动作,如“be wrapped in a blanket”(裹在毯子里);“be enclosed”强调封闭空间,如“be enclosed by walls”(被墙围住)。在抽象意义上,“be covered”更通用,可指范围、费用、报道等。选择时根据覆盖的物理形态或抽象含义决定。

易错提醒

“be covered”语域中性,正式和非正式场合均可使用,但具体含义需结合语境。通常为中性或正面色彩,如“covered by insurance”是积极保障。常见误用包括:1)混淆“with”和“by”,导致逻辑混乱;2)在被动语态中多余添加宾语,如“The area is covered by trees”不能说“The area is covered by trees them”;3)在非正式场合使用“cover”表达“处理”时,可能显得不够具体,需补充说明。避免过度使用“covered with”描述抽象事物,应用“covered by”表示施动关系。
