父母亲常教导孩子，要多听：“to be all ears”，要多看：“to be all eyes”，要守口如瓶：“keep one’s mouth shut”，一个人受人控制时，就是被牵着鼻子走：“lead by the nose”。有些人自视甚高，难免鼻子朝天：“turn their noses up”。有些人喜欢打听人家的秘密，爱“nose into others’ affairs”。如果学生不听教诲，老师会说他左耳进右耳出：“in at one ear and out at the other”。一个有鉴赏音乐能力的人，可以形容他为“a person who has a good ear for music”。债台高筑时：“over head and ears in debt”。掉入情网，难分难舍时，可形容为：“head over heels in love with him or her”。报仇是“an eye for an eye”，方法之一是“give him a black eye”（打得眼圈发青）。
