Present simple: always, often, sometines, never, hardly ever, frequently, usually, every day/year/month/week etc, now and then, all the time
Present continuous: now, right now, at the moment, in this moment, in this very moment, these days, at present
Past simple: yesterday, last week/month/day..., compusii cu ago (ex. two days ago)
Past continuous: nu prea are cuvinte speciale; depinde mai mult de inteles. De multe ori se foloseste cu "while". Ex. I am/was watching tv, while you are/were washing the dishes.
Sper ca te ajuta.
