Question

The verb phrase is underlined in the sentence. What principal part is the main verb?

We are having a wonderful time at the museum.

A.present participle

B.past

C.past participle

D.present

Answer 1

A- present participle.

I think of a participle as a exchange word, or backup for the main object.
EG; Rose likes food.
- you could replace food with anything.

Then the word "having" clearly states that it's happening right now.
