Questions & Answers about Мне больше нравится гулять в парке вечером.
Because the verb нравиться works differently from English to like.
In Russian, the thing that is liked is the grammatical subject, and the person who likes it is put in the dative case.
So:
- Мне нравится гулять... = Walking ... is pleasing to me
- мне = to me
This is why Russian uses мне, not я.
Because гулять is the thing being liked, and it functions as the subject of нравится.
Russian нравиться agrees with what is pleasing:
- Мне нравится книга. = I like the book.
- Мне нравятся книги. = I like books.
- Мне нравится гулять. = I like walking.
Here, гулять is a single action/activity, so Russian uses singular нравится.
