intermittently 在学术写作中常用于描述自然现象或实验数据,如“The species appears intermittently in the fossil record.”(该物种在化石记录中时隐时现),语气客观严谨。在新闻报道中,它用于描述事件发生的频率,如“Services were interrupted intermittently due to the storm.”(服务因暴风雨而时断时续),强调不稳定性。在日常口语中,使用频率较低,更常用“now and then”或“off and on”代替,但若想表达更精确的“间歇性”,也可使用。在商务邮件中,它可能用于描述问题或故障,如“The system fails intermittently.”(系统间歇性故障),语气正式。在法律文本中,它可能用于描述证据或行为的不连续性。总体而言,该词语域偏正式,适用于书面和正式口语。
与 intermittently 近义的词有“sporadically”、“periodically”和“occasionally”。它们都表示“不频繁”,但有细微差别:sporadically 强调时间上不规律且分散,如“He appeared sporadically at meetings.”(他偶尔出现在会议上),常暗示无计划性。periodically 则强调规律性的间隔,如“The alarm sounds periodically.”(警报周期性响起),通常有固定周期。occasionally 语气最弱,表示“偶尔”,频率较低但无中断感,如“I occasionally visit my grandparents.”(我偶尔看望祖父母)。而 intermittently 强调时断时续,可能指有间隔但反复发生。选择时,若强调中断和恢复的循环,用 intermittently;若强调无规律,用 sporadically;若强调规律,用 periodically;若仅强调频率低,用 occasionally。
需要留意
intermittently 语域中等偏正式,在学术和正式写作中常见,但在日常口语中略显生硬,可用更口语化的表达替代。它通常为中性词,但若用于描述故障或症状,可能带有负面隐含意义。常见误用包括:将其与“interminably”混淆,后者意为“无休止地”;或将形容词形式误作副词,如说“The machine works intermittent”而非“intermittently”。此外,注意不要过度使用,以免显得重复。在描述自然现象时,它常与“rain”、“fever”、“signal”等搭配,但在科学语境中,需确保准确性。
