knife 是一个在英语中具有核心地位的名词和动词,其含义丰富且应用广泛。以下是其详细解释:
指一种带有锋利刀刃的手持工具或武器,主要用于切割、刺穿或作为武器。其基本特征包括:
She used a sharp knife to chop the vegetables. (她用一把锋利的刀切蔬菜。) - 参考来源:Oxford Advanced Learner's Dictionary (牛津高阶英汉双解词典) 对 "knife" 作为名词工具的定义。The assailant threatened the victim with a knife. (袭击者用刀威胁受害者。) - 参考来源:Cambridge Dictionary (剑桥词典) 中 "knife" 作为武器的释义。意为用小刀切割或刺穿,尤其指用刀进行攻击或伤害。这个用法通常带有暴力或突袭的意味。
He was knifed in the back during the robbery. (他在抢劫过程中被人从背后捅了一刀。) - 参考来源:Merriam-Webster Dictionary (韦氏词典) 中 "knife" 作为动词的释义。She felt knifed by her friend's harsh criticism. (她觉得朋友尖刻的批评如同背后捅刀。)like a (hot) knife through butter (轻而易举,势如破竹)。under the knife (接受外科手术)。knife-edge (形容极其紧张或微妙的局势)。"knife" 的核心概念是带有锋利刃口的工具或武器。作为名词,它覆盖了从日常厨具到致命武器的广泛范畴;作为动词,它特指用刀进行的攻击性动作。其含义延伸至专业领域(如外科)和文化隐喻中,体现了该词在英语语言和文化中的深度和普遍性。理解其具体含义需紧密结合上下文语境。
/naɪf/,美式发音 /naɪf/。开头的字母“k”不发音,与“knight”“knee”等词类似。knives(规则变化为“knife → knives”)。knifed knifing knifes。kitchen knife(厨房刀)、bread knife(面包刀)。 under the knife:接受手术,如“She went under the knife yesterday”(她昨天做了手术)。 twist the knife:在伤口上撒盐,加剧痛苦,如“Hearing his plans was like twisting the knife”(听到他的计划如同伤口撒盐)。 like a hot knife through butter:形容轻松完成困难任务,如“They cut through the competition like a hot knife through butter”(他们轻松击败对手)。fork(叉子)、spoon(勺子)、blade(刀刃)等餐具或工具。 pocket knife(折叠刀)、butter knife(黄油刀)。 cut with a knife(用刀切)、sharpen a knife(磨刀)。“Knife”不仅是一个基础词汇,其丰富的用法、文化象征和语言变体使其成为英语学习中的重要内容。掌握其发音、词形变化及多语境应用,有助于提升语言表达的准确性和文化理解深度。
