Past continuous sets an activity in progress. Past simple introduces completed events. Past perfect refers to an earlier event. Choose the form by the relationship between events, not by isolated signal words.
| Use | Example | Why it works |
|---|---|---|
| Background | I was reading on the bus. | This places the activity in progress. |
| Main event | The driver stopped suddenly. | This advances the action. |
| Earlier event | Someone had dropped a bag in the road. | This looks back to explain the stop. |
Check: Switching tense without a time reason
Use: Keep the time relationship consistent
Decide which event is background, which moves the story on and which happened earlier.
Read the example and explain the choice before answering. After the exercise, write a new sentence using the same pattern. Revisit any answer you could not explain, even if you guessed correctly.

Use past simple for main events, past continuous for an activity in progress and past perfect to look further back. Example: “I was walking home when I noticed I had lost my key.” The walking is background; noticing moves the story; losing happened earlier.
