as,when,while的区别 as,when,while都表示主、从句的动作或状态同时发生,但三者意义不尽相同.as和when引导的从句既可表示一点时间,也可表示一段时间,从句中的谓语动词既可以是持续性动词,也可以为短暂性动词,经常可以互换使用;while引导的从句通常表示一段时间,从句中宜用持续性动词作谓语.当从句中的谓语动词为持续性动词时,这三者可以通用(前面例句中已有体现),再如:Mother was worried because little Alice was ill,especially as / when / while father was away in France.妈妈担心,因为小艾丽思病了,特别是当父亲远在法国的时候.如果从句和主句要表示一个人的两个动作交替进行或同时完成时,则多用as,可译为“一边.,一边.”.例如:He looked behind from to time as he went.他一边走,一边不时地往后看.As time goes on,it’s getting warmer and warmer..随着时间的推移,天气变得越来越暖了.I thought of it just as you opened your mouth.你一张嘴我就知道你要说什么.(若表示两个短促动作几乎同时发生时,用as的场合多于when.) 当主从句之间表示转折或对比关系时,多用while,不用as或when.如:She thought I was talking about her daughter,while in fact,I was talking about my daughter.她以为我在谈论她女儿,而事实上,我在谈论我的女儿.如果表示从句的动作在主句的动作“之前”或“之后”发生时,多用when(=after),不用as或 while.此外,when还含有“at that moment”的意思(= and then),引起的句子不能放在句首,也不能用as,while来替换.例如:He was about to leave when the telephone rang.他正要离开,忽然电话铃响了.We were watching TV when suddenly the lights went out.我们正在看电视,突然灯灭了.They had just arrived home when it began to rain.他们刚到家,天就开始下雨了.
