Dear all,
As we have seen today, indirect questions are incredibly mentally demanding. I suggest you do this optional assignment: https://dl1.cuni.cz/mod/quiz/view.php?id=506280
to get more practice formulating them. Task 3 in the assignment are indirect questions of the kind that typically appear in presentations. (You can also skip task 1 and 2 and do just 3 if you feel confident.)
Should you feel you want more practice still, just tell me. I can give you something for writing, or we can arrange a call and practice the questions in speaking.
Best regards,
Lucie Malá
