i have gone to the library today.
you have kept a pet for three years.
have you eaten thai food before?
has it rained all day? (tego nie jestem pewien niestety)
who have we forgotten to invite?
we haven't heard that song already.
he hasn't forgotten his books.
she has drunk all the hot chocolate!
have i explained it well?
