Ieri sera ho finito DI studiare molto tardi.
Ho continuato A leggere il libro di Harry Potter.
Actually, our teacher explained that "continuare" always goes with "a." So I'm just wondering, are there other verbs that always goes with "a"? Is there a rule... or just a list of verbs that go with "di" and with "a"? :P And is this just for il passato prossimo?
