This document discusses different types of questions in English and how they are formed. It explains that questions with auxiliaries use helping verbs like "do", "does", "did", "be", and "have" followed by the main verb. Questions without auxiliaries are formed when the question word is the subject of the sentence, so no auxiliary is needed and the verb is in third person form. Examples are provided for questions with and without auxiliaries in both the present and past tenses.

1. QUESTIONS WITH OR WITHOUT AUXILIARIES OBJECT AND SUBJECT QUESTIONS

2. Questions with an auxiliary QUESTION AUXILIARY SUBJECT INFINITIVE/ PAST PARTICIPLE What music do you like? Which CD did he buy? How long has she lived here?

4. Questions without an auxiliary SUBJECT VERB What happened after the concert? Which country won the Eurovision Song Contest? Who writes their songs? Who was talking on the phone? Who has been to New York?
