As to 与 As for 用法小结
在英语中表示就而论有关或至于含义的词语颇多,其中 as to 和 as for 亦表此义,但二者用法不尽相同。
as to 的功能类似于 with regard to, regarding, on the matter of, concerning 等,常用于相当正式的语境中,尤其用于争论和做出决定时。可放于句首或与 wh- 疑问词引导的动词不定式和名词性从句连用(有时可省略),而 as for 无此种用法。例如:
As to the journey, we must decide about that later.
至于旅行,我们必须以后再作决定。
As to the flood, I have heard nothing.
至于那次水灾,我没听到什么。
Nobody could decide ( as to ) what to do.
谁也不能决定该做些什么。
He is very uncertain as to whether it's the right job for him.
关于他究竟是否适合做这项工作,他实在拿不准。
A question arose as to who should be the monitor.
关于谁当班长的问题出现了矛盾。
I want to find out as to whom this bicycle belongs to.
我要打听出来这辆自行车是谁的。
as to 有时用于表示 according to 的含义。例如:
They sorted the eggs as to size and color.
他们按照大小和颜色将鸡蛋进行分类。
as for 和 as to 都可用于句首,引出一个与前一个话题稍微有些不同的话题,但 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。另外, as for 有时表达轻蔑的语气。例如:
We had a delightful weekend in the country. As for the traffic, we had no difficulty.
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。
Much pasture land is under water; as for the grain, most of that has been ruined.
大部分的牧场都进了水,至于谷物,则大部分都被冲毁了。
You can have a bed; as for him, he'll have to sleep on the floor.
有一张床给你,至于他,就只能睡在地板上了。
As for him, I know nothing.
至于他,我一点也不了解。
As for this subject, I couldn't remember.
至于这个题目,我记不起来了。
As for you, I never want to see you here again.
至于你,我永远也不愿在此见到你。
