Remains and becomes are linking verbs in these sentences.

You can substitute "is" for the verbs:

parade is an eventful experience
parade is a fond memory

EVERY sentence has at least one verb!! That sentence has two verbs in it.

Action verbs tell what the subject is DOING.
John hit a home run.

Linking verbs are like equal marks.
Helen is tall and athletic.

If you haven't read and studied the Verbs part in that link I gave you, do it now.

thank you for your help

To identify the action or linking verbs in the sentence and any auxiliary verbs, we will break down the sentence:

"For young children, the parade remains an eventful experience and becomes a fond memory in their adult lives."

1. Action Verbs:
- remains: This is an action verb as it describes the state or condition of something (the parade).
- becomes: This is also an action verb as it describes a change or transformation of something (the parade becoming a fond memory).

2. Linking Verbs:
- is: Although not explicitly mentioned in the sentence you provided, it is implied that the parade is an eventful experience and a fond memory. Hence, "is" functions as a linking verb connecting the subject (parade) with its description (eventful experience and fond memory).

3. Auxiliary Verbs:
There are no auxiliary verbs present in the sentence you provided.

To find action verbs, you can ask yourself "What action is being performed?" or "What is happening?" For linking verbs, ask yourself "What is the subject like?" or "What does it seem/feel/remain/become to be?" And for auxiliary verbs, they are usually helping verbs used in conjunction with a main verb to express tense, mood, or voice. In this sentence, no auxiliary verbs are used.
