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。 副词99%,形容词1% She had notoncespoken to him all the evening.整整一晚上,她都没有跟他讲过一次话。 I see them aboutoncea fortnight.我大约两星期见他们一次。adj.in the past;occurred one time only 同义词 already,before,earlier,formerly,previouslyerstwhile,lateback,back when,bygone,in the old days,in the olden days,in times gone by,in times past,long-ago,old,on one occasion,once only,once upon a time,one,one time before,one time previously,only one time,quondam,sometime,this time,time was,whilomadv.in the past;occurred one time only 同义词 already,before,earlier,formerly,late,previouslyerstwhilea single time,at one time,away back,back,back when,but once,bygone,heretofore,in the old days,in the olden days,in times gone by,in times past,long ago,old,once only,once upon a time,one,one time before,one time previously,only one time,on one occasion,quondam,sometime,this time,time was,whilom alreadyadverb before expected time as of now,at present,before,before now,but now,by now,by that time,by the time mentioned,by then,by this time,earlier,even now,formerly,heretofore,in the past,just now,now,previously,then,up to now anywayadverb by any means anyhow,at all,at any rate,ever,however,in any case,in any event,in any manner,nevertheless,once beforetimeadverb earlier aforetime,already,before,formerly,long ago,of old,once,previously erstwhileadjective former bygone,ex,late,old,once,one-time,past,preceding,previous,quondam,sometime formeradjective previous in time or order above,aforementioned,aforesaid,ancient,antecedent,anterior,bygone,departed,earlier,erstwhile,ex-,first,foregoing,late,long gone,long-ago,of yore,old,once,one-time,past,preceding,prior,quondam,sometime,whilom formerlyadverb previously in time or order a while back,aforetime,already,anciently,at one time,away back,back,back when,before,before now,before this,down memory lane,earlier,eons ago,erewhile,erstwhile,heretofore,in former times,in the olden days,in the past,lately,long ago,of old,of yore,olden days,once,once upon a time,radically,some time ago,time was,used to be,water under the bridge |
