Answer: In Spanish, the subjunctive is found after verbs of emotion in the subordinate clause of sentences with a verb of emotion, and that contain a change of subject from the main clause to the subordinate clause.
Example with verb of emotion: "gustar"
A mí me gusta que tú <u>hagas</u> los deberes.
Translation: I like you to do your homework.
The main clause = A mí me gusta (Subject "yo")
The subordinate clause : que tú <u>hagas</u> los deberes (Subject "tú")
(change of subject from the main clause.)
verb "<u>hagas</u>" second person in the singular , present subjunctive.
