We use the subjunctive to express a wish, possibility or exhortation. After the verbs believe, think, and seem. The Subjunctive is used in the subordinate sentence if the sentence is negative. So the sentences that use the subjunctive are:
1. Es posible (possibility) que ella no recibiera (reciba) su paquete en la oficina de correos
2, Esperaría (Espero) (wish) tener la lista de números de emergencia.
3. Desearía (Deseo) (wish) ver al médico pronto
