1. “Tu n’as pas de vacances cet été?” ● Why does this question use “de” and not “des”?
● Construct a response using “si” to disagree with this negative question.
● How can you emphasize your response by using a disjunctive pronoun

It uses "de" because the word isn't plural. Tip: de +le =du

"Si" is only used to answer a negative question. Si, je vais aller en vacances à Hawaii pour nager.

You could say, Moi, je vais aller en vacances à Hawaii.The disjunctive pronoun makes the statement dramatic by putting "as for me" in front.
