You need to specify clearly what you mean by 非谓语形式 before resorting to a concordancing program. Personally, I am wondering what is your research purpose. Maybe it is better to zero down your topic . Anyway, considerations need to be given to the neighbors of conjugations. This is, again, rather complicated. Theoretical possibilities may not be as easily carried out in practice as we think they are.
Thank you, Dr. Xiao. but how to differentiate the non-finite use of "-ing" & "-ed" forms from the finite use. Say, "taking" in the progressive (finite use) and "taking" used as adverbial or attributive (non-finite use). A similar situation also occurs to "-ed" form.
