Question

请问一下as to的语法问题？

有两个句子不明白，先谢谢了

But any statement as to what it is that our immediate experiences make us know is very likely to be wrong.

The philosopher is troubled by knowledge as to the difficulties of answering the question.

Answer 1

as to其实就是介词，意思是：至于; 关于;按着;根据，相当于about或者according to

But any statement as to what it is that our immediate experiences make us know is very likely to be wrong.任何关于直接经验使我们明白的陈述都有可能是错误的。
The philosopher is troubled by knowledge as to the difficulties of answering the question.
哲学家知道回答这一问题的难度，这一认知使他们颇为困扰。
