Identify the verb phrase. Include main verb and helping verb in the following sentence?

Do you know the three main parts of the brain?

I think the answer is: Do you know

One of those words is not part of the verb phrase. Which one do you think it is?

Hint: You've included the subject in the verb phrase.

Ok. KNOW IS THE VERB?

Yes. KNOW is the main verb. What is the helping verb?

Do is the helping verb? Right?

Yes.

YOU is a pronoun, the subject of the sentence.

Yes, you are correct! The verb phrase in the sentence "Do you know the three main parts of the brain?" is "Do know."

In this sentence, "Do" functions as the helping verb, and "know" is the main verb. The helping verb "Do" is used to form a question in the present tense.
