4. Examples of the Past Perfect

| Use Case | Example Sentence |
|---|---|

| Sequence of Events | She had already eaten when I called. |

5. Comparison with the Past Simple
Here’s a quick comparison between the Past Perfect and Past Simple tenses:
| Aspect | Past Perfect | Past Simple |
|---|---|---|
| Focus | Actions completed before another past action | Actions completed at a specific time in the past |
| Structure | Had + past participle | Past form of the verb |
| Time Expressions | Before, after, by the time, already | Yesterday, last week, in 2020, ago |
| Example | I had finished my homework before the movie started. | I finished my homework last night. |
Key Difference:
- Past Perfect: Focuses on actions that were completed before another action or time in the past.
- Past Simple: Focuses on actions that were completed at a specific time in the past.
Example of Both Tenses Together:
- I had finished my homework (Past Perfect) before the movie started (Past Simple).
(The homework was completed before the movie began.)
