as proof, as evidence, as a girl可以用在句子开头吗？

Children love stories. As evidence/As proof, they fall asleep while listening to music.

请问as proof, as evidence在此处用法正确吗？

中国人把as翻译为“作为”，采用翻译的方法，“作为证据，孩子喜欢边听故事边入睡”看起来没什么问题。

从语法角度，这里as后面跟noun (phrase)，修饰整个句子。The part of speech of as is connective or preposition.

Oxford English Dictionary有

9.
a. Introducing a clause modifying the whole main clause or some part other than its predicate: in accordance with what (is); in the way that.as men, things, etc., go: see go v. Phrases 3a(b).

as a rule: see rule n.1 Phrases 1h. as usual: see usual adj. 4d.

11.
a. Introducing a noun phrase equivalent to a subject or object complement.

所以，as+noun phrase不能修饰整个句子。

至于as a girl，根据11，as可以引导修饰主语的名词，或宾语补语。

但是9a有例外，如as a rule, as usual。

总的来说，as在句子开头，只能引导修饰主语的名词，或某些固定搭配。
