The present and past tenses of _do_ are used as auxiliaries with the
present infinitive, (1) to express emphasis; as, I _do study_ every
evening. (2) To express a denial; as, I _did not do_ it. (3) To ask
questions; as, _Did_ you _see_ him?
When _do_ means _to perform_, it is an independent verb; as, He _did_
his part.
