as the whim takes me
気のおもむくままに
as things stand (now [at the moment, at present])
現状（のまま）では；この調子では
as time goes by
時の過ぎゆくままに
as time goes on
時が経つにつれて
As time [the years] passed, I became more and more interested.
時［年］が経つにつれてますます興味を持つようになった
as to whether this behavior was unlawful
この行為が違法かどうかに関して
As to your final grade, that depends on your final examination.
君の最終成績は，最終試験次第です
as you [we] know
知ってのとおり
As you make your bed, so you must lie upon it.
自業自得の報いはまぬがれない；まいた種は刈らねばならぬ
As you wish.
お望みどおりに（いたします）
