Personnally speaking ,I hope that my English classes will be taught only in English.It‘s a better way to provide a special kind of atmosphere .We all know that we Chinese student ,at least most of us cannot speak English fluently.Even if we can express ourselves ,we just cannot make it fantastic.
If English classes are taught in English ,it will of course be a big chanllege for both teachers and students .As a result,we will definately have a much more space to improve.
