用法辨析

    n. (名词)

  • arm用作名词的基本意思是“臂”,多指人的手臂、胳膊,也可指动物的前肢,亦喻指各种状似手臂的东西。
  • arm的复数形式arms,指“武器(尤指枪支)”。用于比喻时可指“权力”,也可指“兵种”,此时既不能带不定冠词,也不能为数词所修饰。用作定语时亦然。
  • arms可用在另一名词前作修饰语。
  • chance one's arm的意思是“冒险,做冒险的事”; give one's right arm的意思是“付出极大代价”。

    • v. (动词)

  • arm用作动词的基本意思是“把…武装起来”,可以表示“提供”“配备”“支持”,也可以表示“以(武器)装备”。就目的而言可仅指为加强力量或安全做准备而提供,也可指为有效行为或作战而准备进攻或防御的装备。arm引申还可指精神上、道德上或身体上的准备。
  • arm可用作不及物动词,也可用作及物动词。用作及物动词时,以被武装的对象作宾语。
  • keep at arm's length属于习语，有时指“避免同……亲近”。The mother kept her baby at arm's length, thinking that he might try to kiss her. 值得注意的是arm's前不加an。
  • at arm's length指“伸臂可达之处”，单用时，也不加an。He held the picture at arm's length to show it to me. 他把照片举在一臂之远的地方给我看。
