I think it's very necessary to improve our English.I'd like to offer some suggestions.
First of all,I think an English class should be both interesting and meaningful.Once students feel relaxed,they will learn English much better.Teachers may tell us jokes in English,by which we can improve our listening.Then teachers can also ask us to repeat the jokes,so it will help us with our oral English,too.
Secondly,I think we should also spend some time watching English movies or learning to sing English songs.I think English movies are full of fun and good sentences,it will help us both speak better and write much better.English songs are popular,it's always great to do popular things.
I hope we can have much more fun learning English.
