(-) julia doesn't often spend her holiday in the park
(?) Does julia often spend her holidqy in the park?

pake does karena ada huruf s setelah spend. kalau dirubah menjadi negative, s pada spends akan menghilang karena menjadi doesn't.
kalau di interrogative gitu juga. s nya hilang karena diganti jadi does di dpn kalimat.
