as to与as for的区别 - 柯帕斯英语网

关于 as to 与 as for 的区别，网上有不少介绍，但感觉都没有完全讲清楚。

请英语答疑网的专家老师帮忙分析和总结一下，万分感谢。

1. 用于句首的 as for 与 as to 意义很相近，它们都能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。

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

Much pasture land is under water; and as for the grain, most of that has been ruined.(CEU) 大部分牧场都进了水，至于谷物，则大部分都被冲毁了。

As to the journey, we must decide about that later.(Palmer)关于旅行，我们必须以后再作决定。

As to that, I haven’t decided yet. (LDCE)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：

Nobody could decide (as to) what to do. (LDCE)谁也不能决定该做什么。

He’s very uncertain as to whether it’s the right job for him. (LDCE)关于他究竟是否适合做这项工作，他实在拿不准。

The numbers are a hint as to how to decipher the rest of the message.(Dan Brown,The Da Vinci Code)这些数字是破译其他信息的线索。（《达.芬奇密码》）

as for, as to, as with这是三个很常用的短语介词（或成语介词）。

1. as for, as to "就......而论；至于......"，介绍新话题或对已谈过的事作进一步的说明，放在句首。这样用时，as for和as to没有什么区别；但as for似乎更常用一些。

As for me, I'd rather stay at home. 至于我，我想我还不如留在家里。

2. 以下三种情况要用as to。

① 表示about“关于，有关”的意义。多放在句中，后接名词、代词或名词性从句。

He wrote to me as to his work and study. 他写信告诉我有关他的工作和学习的情况。

② 表示according to“根据，按照”的含义。

They sorted the apples as to size and color. 他们按照大小和颜色将鸡蛋进行分类。

③ 表示in proportion to“与......成比例，与......相称”的意义。

Her expenditure is not as to her income. 她的收入和开支不相称。

3. as with“正如，与……一样”

As with what I said, he failed again. 正如我所说的,他又一次失败了。

▲ as is the case with常用来构成比较状语从句。例：

As is the case with a lazy schoolboy, Tom always leaves what should be done today for tomorrow. 正像懒惰的小学生一样，汤姆总是把今天该做的事留到明天。
