All the cases of Vinf. nonpast ni tsureteltsure can be rephrased with - ba -.
hodo which indicates that in proportion to the increase of extent 1 degree of
action or state, s.t. happens, as in [I] and [2]. However, - ba - hod0 can be
paraphrased by ni tsureteltsure only when the former expresses some change
or process.

There is another fundamental difference between the two structures under
comparison. In front of ni tsureteltsure comes only a verb or noun, but in
front of - ba - hod0 comes not only a verb but also an Adj(i / na).
