They are listed like this, right?

Past tense, ate; Perfect, eaten

1. Use the Past tense form when you are talking about one event/action in the past, like this,

I ate dinner yesterday. (Past)

2. Use the Prefect form in four ways:

A. with 'have/has' when you want to express an event/action taking place in the past and continuing up unit right now, like this,

I have eaten dinner. (Present Perfect)

B. with 'had' when you want to connect two events/actions in the past, like this,

I had eaten dinner before you called. (Past Perfect)

Note that, the event/action that happened first takes 'had -en/-ed', like this,

Event #1: I had eaten dinner
Event #2: you called

C. with passive voice, like this,

I ate a banana (active voice)
A banana was eaten. (passive voice)

D. as an adjective to modify nouns,

A half-eaten banana was in my bag. ('banana' is a noun and 'eaten' functions as an adjective telling us what kind of banana.)

All the best, :D
