Simple Tense Verbs
* Focus on the present, past, or future: They describe actions happening right now, in the past, or in the future.
* Don't use helping verbs: They stand alone.
* Examples:
* Present: I *walk*, she *sings*, they *eat*.
* Past: I *walked*, she *sang*, they *ate*.
* Future: I *will walk*, she *will sing*, they *will eat*.
Perfect Tense Verbs
* Focus on completed actions: They describe actions that are finished, regardless of when they started.
* Always use helping verbs: "have", "has", or "had".
* Examples:
* Present Perfect: I *have walked*, she *has sung*, they *have eaten*.
* Past Perfect: I *had walked*, she *had sung*, they *had eaten*.
* Future Perfect: I *will have walked*, she *will have sung*, they *will have eaten*.

Key Differences:
* Time focus: Simple tenses are about specific times, while perfect tenses focus on completion.
* Helping verbs: Simple tenses don't use helping verbs, while perfect tenses always use "have", "has", or "had".
* Meaning: Simple tenses describe actions directly, while perfect tenses emphasize the state of completion.
Examples to distinguish:

* Present perfect: "I *have eaten* breakfast." (Focus on the completion of eating breakfast)
* Simple future: "I *will eat* dinner." (Focus on a future action)
* Future perfect: "I *will have eaten* dinner by 7 pm." (Focus on the completion of dinner before a specific time)
