Subj. + 以为 ⋯⋯

The part that follows 以为 will be a whole phrase that is actually incorrect information. Note that while it's quite common to refer to things that happened in the past, it could also refer to a situation in the present or even the future. It can also be used for commands, usually of the negative "don't think that..." type.
