About communicative types of parenthetical constructions with mental verbs

The paper deals with parenthetical constructions (PC) with mental verbs (znat’ ‘to know,’ ponimat’ ‘to understand,’ verit’ ‘to believe’ and the like) in the 2nd person form. The appeal group (2nd person forms): Smotri, Dolli! My, znaesh', mozhem eto proverit' ʻLook, Dolly. We can check that, you knowʼ is considered in comparison with the modal group (1st person forms): V byuro gostinitsy gorbonosyi muzhchina s ochen' temnym, dumayu, proshlym, kotoroe stoilo by rassledovat', peredal mne soobshchenie, napisannoe ego rukoi ʻAt the desk, a dignified Roman-nosed man, with, I would think, a very dark past, handed me a message written with his own handʼ. Modal PCs are used in the declarative sentence P (On, dumayu, pridet ʻHe'll come, I thinkʼ) and in the interrogative sentence P (On, dumaesh', pridet? ʻWill he come, do you think?ʼ); PC itself has a neutral communicative status. Appeal PCs are used only in the declarative sentence P, but PC itself has an interrogative communicative status, cf.: Sto dvadtsat' odnu Margaritu obnaruzhili my v Moskve, i, verite li, ni odna ne podkhodit ʻWe found one hundred and twentyone Margaritas in Moscow, and, would you believe it, not one of them was suitable!ʼ (you know and you understand have an interrogative and a neutral communicative status: Ya, znaete, ochen' lyublyu nauku ʻI'm a great fan of science, you knowʼ).
