  • What are you doing there? (present continuous)
  • What were you doing in Santiago? (past continuous)

Notice how we combine have and been to form the present perfect continuous.
  • How long have you been working in Santiago?

We also use the verb be with the past participle to make passive forms of the verb.
  • Where are you based? (present simple)
  • When was your last paper on climate change published? (past simple)
