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.
I hope we can have much more fun learning English.
