Doctor, can I drink wine and smoke cigarettes ? Доктор, можно ли мне пить вино и курить сигареты ? - when asking permission we often use this small "ли" particle, it is more polite, I suppose. Though I don't know if there's a rule about it's usage. 2. In this room it’s hot, I cannot breathe В этой комнате жарко и нечем дышать - for some reason the form "дышится" used rarely in speech. I can remember it being used only in "легко дышится". I suppose it's just cultural weirdness :) 3. In my school there was no gym В моей школе нет спортзала. - не существует is does not exist. There is no is more like нет. 4. Some people believe that there is not any virus Некоторые люди считают что не существует никакого вируса - for some reason we don't use "верится" in positive cases. It is used in "Не верится", which is rather negative. And there is a difference between "некоего" and "никакого". First is a reference to a certain virus, that is known to all in the dialog, but nobody wants to pronounce the name aloud. Second is literally "any" 5. Why do I want to cry without any reason? Почему мне хочется плакать без причины? - because our grammar is a hellhole :D 6. We managed to sleep well not only because we were tired. The beds were comfortable.
