As to 和 As for 的用法有什么区别
as for (至于,就……方面说)和 as to (至于；关于)这两个复合介词在含义上相当接近,但在用法上差别很多.下面谈它们的这些差别.
1．as for
1)用以转换话题：在有前文的情况下as for总是出现在下文的句首,用来引出另外一方或者新的谈话内容,但与前文内容也有一定的联系,起到补充前文又突出后文的作用,使之与前文形成对照,译作“至于”.例如：
①You have a bed；as for him,he'll have to sleep on the floor．
②Much pasture land is underwater；and as for the grain, most of that has been ruined．
2)用以表现态度：as for还可以用来表示讲话人对某人或某物持有“轻蔑”或“冷淡”的态度,甚至有憎恶之感,讲话时要重读引出的词语并在其后稍作停顿,以示强调,口气上带有嘲讽意味,译作汉语的“至于……嘛”.例如：
①As for you,I never want to see you here in my home again．
②As for his songs,I suppose you've read the sarcastic reviews !
2．as to
1)表示涉及某点：as to常放于句中,表示“关于……方面”、“有关……之事”,但为了突出要提及的人或事之时,也可将as to置于句首,以示强调.但只涉及内容,而不涉及讲话人的态度.例如：
①His wife,an old teacher,has no complaint as to salary．
②As to your ability to overfulfil the target,I never had the slightest doubt．
2)用以重提旧事：as to引出的内容都是前文曾经提到过的或者谈话对方都有所了解的,表示“说到”之义.,例如：
①As to doing that,I haven't decided yet．
②As to the question you raised in your last letter,I think that it is unanswerable．
3)用于提出问题：as to必须位于句中,前面出现的大都是表达某种心理活动的动词,形容词或名词,其后引接出wh-clause或who-to-v结构,表示“在……的问题上”、“就……问题来讲”,所引出的问题都有很强的针对性.但有人认为这里的罄to显得多余,去之亦通.所以,有时也不必译出.例如：
①There is some doubt as to whether the proposal is practicable．
②I enquired of the clerk as to which documents were needed．
4)引出做事的依据：as to还有“按照”、“根据”的含义,而as for则无此义.例如：
①The shoes are correctly placed on the shelf as to size and colour．
②The items on the agenda are listed as to order of importance．
综上所述,as for 和 as to在确切含义的表达和具体用法上都是有很大差别的,不能将二者混为一谈.
as to 和as for有啥区别!
as to 和as for意义接近，都有至于、 关于、说起的意思，用法区别如下：1、as for 在语体上不如 as to 正式，并且着重话题的转换，也就是说，它所引导的是前面尚未提到过的新的事情，因此，它不能用于文章的开头。【例句】As to that, I haven’t decided yet. 此时用于句首，不能用as for关于那件事，我尚未做出决定。2、as to 常常与 wh-疑问词引导的动词不定式和名词从句连用（有时可省略），而 as for 却没有此种用法：【例句】Nobody could decide as to)what to do. 谁也不能决定该做什么。扩展资料：例句（1）As for me, I'd prefer this one to all the rest. 要是我，我会首选这个。（2）As for the hero's fate, I will hold it over for my next book. 关于主人公的命运问题，我将留到下一本书中再谈。（3）As for work, we can't compare with those young people. 说干活，咱们可比不上人家年轻的。（4）As for her, she has nothing to complain to. 至于她，她没有什么可抱怨的。（5）As to the ideological work, we should never go about impetuously. 对于思想工作，千万不可操切从事。（6）To them, as to all Christians, this is a holy place. 对他们以及所有基督徒来说，这里是一处圣地。（7）They paused at the top of the stairs, doubtful as to which way to go next他们在楼梯顶部停住了，不知道接下来该往哪边走。（8）Don't be so shortsighted as to see only what is under your nose. 不要这样目光如豆，只看到鼻子尖下这一点点。
