“Do” is also used to ask questions about the occurrence or non-occurrence of any action taking place in the present. “Do” is used by “I, you, we, they” and plural nouns, while “Does” is used by “he, she, it” and other singular nouns. For negative questions, “not” is used with “do” or “does”. The structure is — “Do/Does” + noun/pronoun + “verb”.   _{Your Comment}
