REPORTING QUESTIONS
When we report what people say, we usually change the tense of the verbs to reflect that we are reporting;This pattern is followed when we report questions and there are also other important changes between direct questions and reported questions
YES/NO questions:
Direct question: Do you like working in teams?
Reported questions: He asked if I liked working in teams
We don't use auxiliary verbs.
