Luyện ngữ pháp - Destination B2 (Unit 21: Grammar - Reported speech / reported questions / reporting verbs)
• We use reported questions when we want to say what someone else asked. eg Tim asked Tom if he wanted to go shopping with him.
• We use the same rules regarding tense, pronoun and time and place word/phrase changes with reported questions as we do with reported speech
• In reported questions we don't use the question form or question marks (asked if he could ... ).
