Two past tenses do the heavy lifting of English storytelling: the Past Simple for completed events (I watched a film, She called me at 8 p.m.) and the Past Continuous for action in progress at a past moment (I was watching a film, She was working at 8 p.m.). The classic combination — I was reading a book when the phone rang — uses both: the continuous for the longer background action, the simple for the shorter interrupting one. The rule that anchors the choice: while normally pairs with the continuous; when normally introduces the simple.
This worksheet builds B1 storytelling fluency by combining the two past tenses in narrative contexts. Students choose between simple and continuous based on event sequence, identify when/while triggers, and produce their own short stories.
What’s inside:
- Grammar Box contrasting completed events (simple) with background action (continuous), plus the when/while rule
- Gap-fill in a short story: choose between Past Simple and Past Continuous to complete a narrative
- Sentence combining: turn two simple sentences into one using when or while
- Personalised production: write four sentences describing a memorable moment when something was happening and something else interrupted
- Full Answer Key plus Teacher Notes on the most common B1 narrative-tense errors
Common mistakes addressed: using the continuous for completed events (I was finishing my homework at 8 p.m. where the event finished at 8), wrong while/when pairings, and missing was/were in the continuous (I reading when she called).
For: Adult and teenage learners (14+) at CEFR B1, in intermediate classes, 1:1 lessons, or self-study. The simple/continuous contrast is heavily tested in Cambridge B1 Preliminary (PET) Writing — particularly the story task, where the two tenses must alternate naturally. Part of the Past Tenses collection — the natural next step is Past Simple: Irregular Verbs, which strengthens the high-frequency verb base that storytelling depends on.
