hi,how can we show to be verbs in inflection?

I am not sure of your question, but it seems like you want to make sentence (tree) diagrams that show the details of verb forms.

I don't know if there is any standard way, but the resource below covers both finite and non-finite verbs. Here is the chapter that covers diagramming verbs in quite some detail.
