Topic Explanation and Use
Core idea
Tense choice becomes easier when you decide the timeline before the verb form.
Tense choices place actions on a timeline and show whether they are finished, ongoing, repeated, or connected to another time point.
Use tense accurately by deciding the time first and the meaning second. Readers should be able to follow your timeline without stopping to reinterpret the verb forms.
At A2 level, keep sentences short and clear first. Add extra words only when they help meaning.
Use it here
- Find the time signal or implied timeline before you choose the verb.
- Keep the tense stable until the timeline genuinely changes.
- Use perfect forms when you need to connect an earlier action to another time point.
Watch it work
Remember this
- Mark the timeline first with a time word or situation clue.
- Choose simple, continuous, perfect, or perfect continuous from the meaning.
- Keep the reference point stable inside the sentence.
- Use tense shifts only when the timeline really changes.
- Check that the final verb form agrees with the time marker.
