1. What do you like?
2. What don't you like?
3. What do you not like?
4. What do you dislike?
(Can we use all the expressions? What about #3? Do you use Sentence 3 frequently? What other expressions can we use if we want to ask like this?)
#3 is a bit stilted, but all are fine. #1 is the most commonly used. #2 is usually used in a joking way!!
