When converting a direct question into reported speech, several changes occur:
Reporting Verb: The introductory phrase "She asked me" is used.
No Inverted Commas: The quotation marks are removed.
Question Word Retained: The question word "how often" is kept.
No Auxiliary Verb in Subordinate Clause: The auxiliary verb "do" is removed.
Tense Change (Backshift): The present simple tense ("do you go") in the direct speech changes to the past simple tense ("I went") in the reported speech. This is known as "backshift."
Pronoun Change: "you" changes to "I" to reflect the perspective of the person reporting the speech.
Word Order: The word order changes from interrogative (question) to affirmative (statement) within the reported clause ("how often I went" instead of "how often did I go").
