Hi teachers,<br/><br/>Information to consider:<br/><br/>The old lady asked him if he had knocked.<br/><br/>Would you correct me if I am mistaken?<br/><br/>The reported sentence above has two clauses, 'The old lady asked him' and 'he had knocked'.<br/><br/>They are connected by the pronoun 'if'.<br/><br/>Can I include 'if' and say the second class is 'if he had knocked'?<br/><br/>Thanks in advance
