I think in English it would be more natural to say ' You don't hate me, do you?'
After a struggle, Duo has marked me correct for the following: 'do not you hate me'.
Either. Just use it like how you do in English. I think "Bạn không ghét tôi à?" is more natural. "ư" has been out of date for decades.
Catch 22 again. Using preselected words, 'don't' is not available, only 'do'. But WRONG if you use it!!!
the words supplied for the put-together sentence were not all there, and not capitalized.
"tôi ư" spoken like no other word I have heard thus far. " glue" best I can make out of it. Oh, well, maybe twenty or more times I will hear "tôi".
Yes, there should be a slow down button, and then a word bank. And no audio exercises at all until you've seen the construction in writing/reading first (like, how can you write down a phrase/word for an answer that you've never seen before??).
Introducing vocabulary you've never seen via audio exercises is really really REALLY bad form.
