Как понять принцип:

• ago, yesterday, last month — законченное прошлое, поэтому обычно используется Past Simple:
  I joined … ago; I had a test yesterday.
• already, yet, just, ever, never, for, since, before часто употребляются с Present Perfect:
  have/has + третья форма глагола
  I have already done it.
• usually, often, rarely показывают привычку — чаще нужен Present Simple.
• right now, at the moment, these days обозначают действие сейчас или в текущий период — часто используется Present Continuous:
  am/is/are + глагол-ing.
• for указывает продолжительность: for five years; since — начальный момент: since I was ten.
• while — «в то время как», а when — «когда».
