The document discusses using the subjunctive mood with verbs and expressions of emotion in Spanish. It explains that the subjunctive is required in the subordinate clause when the main clause expresses an emotion. However, the infinitive is used after expressions of emotion when there is no change of subject between clauses. It also notes that the expression "ojal叩" is always followed by the subjunctive, and using "que" with it is optional. The document concludes with an exercise involving filling in verbs in the subjunctive mood.
