Answer:
My Cat (Noun Phrase)
chased the mouse (Verb Phrase)
The frightened mouse (Noun Phrase)
hid under the rug (Verb Phrase)
Frustrated, the angry cat (Noun Phrase)
stalked off (Verb Phrase)
Step-by-step explanation
A noun is a person, place, or thing. The cat, the mouse, and the rug are all nouns. Likewise, chased, hid, frustrated, and stalked are all verbs. Which are words which show action. The filler words (my, the, under, angry, off, etc.) are modifiers. Which as I said, are filler words. It wouldn't be a complete sentence without modifiers. I hope this helps!
