as for和as to的区别

??as for用来转换话题：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。 例：你可以睡在床上，至于这些孩子，他们只能睡地板了。You can have a bed, but as for the children, they have to sleep on the floor.

例：在乡下我们度过了一个愉快的周末。至于交通，我们没有遇到任何困难。We had a delightful weekend in the country.??As for the traffic, we had no difficulty.

??as for还经常用来表示亲蔑、冷淡的态度的。

例：至于John，我再也不想见到他了。As for John, I never want to want to see again.

例：我只想叫你来，至于其他人，我不在乎。I only want you to come; as for others, I don’t care.

例：至于回去，那是不可能的。As for going back, that is out of the question.

(2)??as to

??as to在表示“关于”“至于”时，一般情况下意义和功能类似于with

regard to, regarding, concerning等。

??as to可用于引出一个与前文有所不同的话题，此时与as for表示话题

转换的意义相似，但比as for更为正式，但一般情况下，as for?更强调话题的转换。

例：…至于那个技术问题，我以后再详细讲。…As to that technical problem, I will deal with it in detail later.

??as to用以重提旧事：as to引出的内容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：至于你提出的事项，我认为应当尽快解决。As to the matter you brought up, I think it should be settled as speedily as possible．

例：至于你上次信中提及的问题，我无法回答。As to the question you raised in your last letter, I think that it is unanswerable． ??as to常与表示询问、争论、疑问等动词连用。

例：我对你女儿的能力一点也不怀疑。I have no doubts as to your daughter’s ability.

??as for后面通常直接名词或动名词，as to后面可接动名词、名词从句或

疑问词+不定式的短语

例：He asked my advice as to what to do. [接疑问词+不定式]

例：We made enquiries as to when the next train would be leaving. [接名词从句]

例：I am terribly uncertain as to whether he is the right man for me. [接名词从句]
