Questions: Verb Phrases and Helping Verbs

Question 1

In the sentence 'She has been waiting for three hours,' what is the complete verb phrase?

• A. waiting
• B. has been waiting
• C. has been
• D. been waiting

Answer: (B)

'Has' and 'been' are both auxiliary verbs supporting the main verb 'waiting.' The complete verb phrase is 'has been waiting' — this combination expresses the present perfect progressive aspect, showing an ongoing action that started in the past. Identifying only 'waiting' loses the information that the action is ongoing and has lasted to the present.

Question 2

In the sentence 'The locked door blocked the exit,' 'locked' is part of a passive verb phrase.

• T. True
• F. False

Answer: False

This is a key misconception. In 'The locked door,' 'locked' is a participial adjective modifying the noun 'door' — it describes what kind of door it is, not what is being done to it. A passive verb phrase requires an auxiliary: 'The door was locked by the security guard.' Without an auxiliary verb, a past participle is functioning as an adjective, not as part of a verb phrase.

Question 3

What information do auxiliary verbs add that the main verb alone cannot express?

Model answer: Auxiliary verbs signal tense (will run = future), aspect (has run = perfect; is running = progressive), mood (might run = possibility; should run = obligation), and voice (was run = passive). Without auxiliaries, a verb alone cannot distinguish between these meanings.

The main verb carries the core meaning of the action, but auxiliary verbs are the grammatical machinery that locates the action in time, frames its completion status, expresses the speaker's attitude toward it, and determines whether the subject is acting or being acted upon. Recognizing the full verb phrase is therefore essential for accurate interpretation of a sentence's meaning.
