二、词义辨析:
immediately,instantly,presently,directly,shortly,soon,at once,right away
这些副词或副词词组均有“立刻,马上”之意。immediately指做完一件事后,立即就做另一件事,中间一般没有明显的时间间隔。instantly指恰恰就在此刻,一秒钟也没耽误。presently指不久、即将。directly和immediately同义,指毫无迟疑。shortly和soon同义,指动作发生或完成的速度之快。soon常用词,指行动快,完成速度快。at once口语中常用,语气强烈,指时间紧迫,一刻也不能耽误。 right away主要用于美国英语,语气稍弱于at once,强调动作迅速。
