1. Basic Inversion
* For simple questions: Invert the subject and the verb.
* Example: "She is happy." becomes "Is she happy?"
* For questions starting with "wh" words (who, what, when, where, why, how): Place the "wh" word first, then invert the subject and verb.
* Example: "He went to the store." becomes "Where did he go?"
2. Auxiliary Verbs
* If the sentence already has an auxiliary verb (do, have, be, can, could, will, would, etc.): Move the auxiliary verb to the beginning of the sentence.
* Example: "They have been eating." becomes "Have they been eating?"
* If the sentence does not have an auxiliary verb: Add "do" or "does" before the main verb, and then invert the subject and the auxiliary verb.
* Example: "She likes apples." becomes "Does she like apples?"
3. "Wh" Questions with Compound Verbs
* For questions with "wh" words and compound verbs (verbs with "to be" or other helping verbs): Place the "wh" word first, then move the helping verb to the beginning of the sentence.
* Example: "She is playing the piano." becomes "What is she playing?"
4. Questions with Prepositions
* If the question involves a preposition: The preposition usually goes at the end of the question.
* Example: "He is looking at the book." becomes "What is he looking at?"
5. "Do" for Emphasis
* To emphasize a question: You can add "do" or "does" even if the sentence already has an auxiliary verb.
* Example: "He will go." becomes "Do you think he will go?"
Important Notes:
* Don't forget the question mark (?).
* The intonation of your voice will also indicate a question.
* The rules for forming questions can be more complex with different verb tenses and sentence structures.
* Practice and familiarity with the rules will help you become more comfortable with forming questions.
