hI TORSTEN,
THIS IS FREEDOMJL2, i'M CONFUSED ABOUT QUESTION TAG. i THOUGHT IN THE QUESTION TAG, THE 1ST PART OF THE QUESTION IF IT IS POSITIVE, THE TAG WILL BE IN NEGATIVE AND VICE VERSA. COULD YOU EXPLAIN IN THE EXERCICE:
i WANT YOU TO GIVE ME MORE MONEY- THE QUESTION TAG IS: YOU DO, DO YOU
THANKS.

[Mahmed]

the question tag for the question a/m is don't you? because the sentence is positive , so the q.tag should be negative

thank you
mahmoud
