There are some kind of sentences where subjunctive is used with the negative form as well:
- with imperative sentences:
Ven
No vengas.
- with some compound sentences when the subject of the main clause is different from the subordinate (well, in this case there isn't the negative form
):
A mí me gusta ir a pasear.
A mí me gusta que tú vayas a pasear.
- etc.
