Three sentences that include PROPER NOUN, a HELPING VERB, and an ACTION VERB.

A helping verb always stands in front of a main verb. For example, in the sentence, "Shyla can ride her sister's bicycle," the helping verb can stands in front of ride, which is the main verb. More than one helping verb can be used in a sentence.

Proper noun:

My dog's name is Zoom.

'Zoom' is a proper noun, because it is a name.

Helping verb:

My shoe has a tag on it.

'Has' is a helping verb. There are large lists online of all the helping verbs.

Action verb:

I jump over the cracks in the sidewalk as I walk.

'Jump' is an action verb. Action verbs show an action being done, ex. run, leap, sing, dance, etc.
