Some students don't like English .What should I do

First,i'm wonder that how old your students are?
If they are very young,just like pupil,you need to make the class more interesting and atractive,for example,using children's songs,playing some little games or something like that.
If they are teenages,songs and movies may be the best choice.
if they are university students,do tell them some foreign customs and history stories.they wiil be into that.
I hope that works.Good luck!

language is for communication , talking with them in English , looking at the issues from a new aspect , you will know why they do not like it .

Try your best to do everything you can to improve their English,and let they know the importance of English!
