Choosing simple vs continuous forms for present, past, future
Simple = base/+ed/irregular; Continuous = be (am/is/are/was/were/will be) + verb-ing
Negate be for continuous; use do/does/did not for present/past simple
Invert be for continuous; use do/does/did for simple
💡 Use stative verbs with simple, not continuous (know, like).
✓She works from home. / She's working today.
✗She is working from home every day (if habitual).
Habit = simple; temporary = continuous.
✓I watched TV when you called. / I was watching TV when you called.
✗I was watch TV when you called.
Completed vs in-progress past.
✓I'll call you later. / I'll be calling you around 6.
✗I'll calling you later.
Future simple vs future continuous.
