GRAMMAR POINTS TO REMEMBER
- The Background vs. The Interruption: When telling a story, use the Past Continuous (was/were + V-ing) to describe the “background scene” or an action that was in progress (e.g., I was waiting for the bus). Use the Past Simple (V-ed/Irregular) for the sudden, short action that “interrupts” the background (e.g., when I saw Mark).
- Keywords:
- “While” / “As” are usually followed by the Past Continuous because they mean “during the time that” (e.g., While I was walking…).
- “When” / “Suddenly” are usually followed by the Past Simple to introduce the sudden interruption (e.g., …when my phone rang).
- State Verbs / Quick Actions: Verbs that happen in a split second, like notice, spot, run into, bump into, realize, are almost always used in the Past Simple. Do not use them in the continuous form (never say I was noticing or I was running into her).
