常见误用提醒

使用 perseveration:He has a perseveration to talk too much. → He exhibits perseveration in his speech. (perseveration 是名词,不应与 'to' 不定式连用表示倾向;正确用法是作为名词描述状态,常与动词如 'exhibit' 搭配。)

使用 perseveration:Perseveration means persistence in a good way. → Perseveration refers to pathological repetition, often in a clinical context. (perseveration 特指病理性或非自愿的重复,与积极的 'persistence'(坚持)不同;应强调其医学含义以避免混淆。)

使用 repetition:He did a repetition of the exercise. → He did the exercise with repetition. (错误在于将“repetition”误用作可数名词表示单次重复;正确用法中,“repetition”作为不可数名词,常与介词搭配表示重复的方式或过程。)
