at once, directly, immediately, instantly, presently, right away这组词组的共同意思是“立即”“马上”。其区别在于: 1.at once主要指动作迅速,但中间多有一段距离,且at once比immediately意味更强。例如: I'm leaving for Rome at once.我马上去罗马。
He gave orders for the work to be started at once.他下令立即开始那项工作。2.immediately侧重指时间“紧接着”。例如: I came immediately after I'd eaten.吃过饭我立即就来了。
Please close your books immediately and answer these questions.请立即合上书,回答这些问题。
I left immediately when the clock struck twelve.钟刚打12点我就离去了。3.right away经常出现在美式英语中。例如: I'll do it right away.我立即去办。
He had written down a list of things to do right away.他已写下须立即做的事情。
Don't expect them to approve of the design right away.不能期望他们马上批准这项设计。4.instantly也是指动作迅速,但它更强调的是同时发生,中间有很短的距离或无距离。例如: The electrician went instantly in answer to the phone call.电工师傅一接到电话马上就去了。
He was killed instantly in a car accident.在车祸中,他当场死亡。5.directly强调“直接地”,多与“迂回绕过”相对。例如: Whether he sailed directly across the bay or coasted round it is uncertain.他是径直驶过海湾,还是沿海岸迂回绕过的,现在还无法确知。6.presently强调过一会再去做某事。例如: I will do the dishes presently, but I want to finish the story first.我过一会去洗碟子,不过我想得先看完这篇故事。at once, soon这两个词组的区别是:soon表示“不久”“很快”,强调时间很短; at once表示“马上”“立刻”,强调动作随即发生。例如: He soon became active in the class.他在班上很快就变得活跃起来。
When I heard the knock,I opened the door of the room at once.我听到敲门声马上就把房门打开了。once，as soon as两者均为从属连词，引导时间状语从句，都表示主句的动作紧跟在从句的动作之后发生。 once除表时间外，还表示条件，一般译作“一旦…就…”。 as soon as强调的只是时间，译作“刚…就…”或“一…就…”。 来自one,一，-ce,副词后缀。once in a blue moon罕见的，极少的，难得…at once立刻once or twice一两次all at once同时once and for all彻底地once upon a time从前once bitten, twice shy一朝被蛇咬,十年怕井…once more再一次once again再一次once too often又一次once in a while偶尔once and away一次了解地not once一次也不more than once不止一次好几次…once and again一而再gone过去的for once就这一次every once in a while间或once in a way有时偶而for this once就这一次

conj.连词
once用作连词时可引导时间状语从句和条件状语从句。用于前者时意为“一旦…就…”,所引导的从句多很短; 用于后者时意为“只要”,这种条件从句似带有时间条件的含意。 once引导的从句中有些部分可以省略。
