一定英文翻译短语

在一定程度上 to some extent ; partly ; to a certain extent ; in some degree一定的 bound ; definite ; certain ; determinate请一定要通知我 Please keep me informed ; Please keep me accused

without fail 一定，必定by all means 一定，务必，尽一切办法be bound to 一定会，肯定all to nothing 一定，百分之百must be 一定，一定是

certain 英[ˈsɜ:tn] 美[ˈsɜ:rtn] adj. 某一; 必然的; 已确定的; pron. [动词用复数] 某些; [例句]She's absolutely certain she's going to make it in the world她坚信自己会出人头地。[其他] 比较级：more certain 最高级：most certain

好多年...must就是必须,最强烈的表达,例如学校的规章制度之类的.have to 是不得不,没有办法,不情愿但还是要做的事情be sure就是肯定I am sure he will come.That man can't be Mr.Liu.You have to learn English.You will like her.(很多时候一定并不是要翻译成以上几种的,像这里will就能表达"一定"了)(不过must在这里还是可以用的,像你说的,you must like her,没有什么大的不妥当.)其实不是"一定是一定要"之类的问题了,没有那么微妙的东西的.你迷惑的其实就是"一定没有""一定不"的翻译怎么翻.一般来讲,一定不应该翻译为can't be.但是像你那样,在完成时态下,怎么用都不自然了.你那样卡的确不好,也不能那么翻.(这里硬用must其实是因为中文思维)1.oh,I bet you haven't tasted this yet.You haven't had this yet, of course.oh, you surely haven't had this yet.2.I am pretty sure you didn't turn up for school yesterday!(注:这里用完成时态不恰当)You definitely didn't go to school.3.He just hasn't come yet,don't worry.oh,he must be on his way, there's no need to worry.(这里是稍微变化了一下意思,很自然地把must用进去了)He just can't be here right now.don't worry.总结,一旦碰到你的情况,就是要在否定的情况下表示一定的意思,有3种方法:一.用副词来表示(surely,definitely).二.用"我肯定"来表示(I bet我打赌I am sure我确定I believe我相信).三.巧妙地转化句子,例子看3里的那句.(四)或者,不用加东西,直接把否定的东西说出来,也有肯定的意思,这个具体看语境.
