What two parts make up t he present progresive tense?

Answer 1

Present progressive (or continuous) is made up of to be(as a helping verb) and a verb ending in -ing. E.g. The keeper is feeding the elephants over there.

Answer 2

The present progressive tense is made up of the present tense of the verb "to be" (am, is, are) and the present participle form of the main verb ending in -ing. For example, in the sentence "She is dancing," "is" is the present tense of "to be" and "dancing" is the present participle.
