I prefer my English classes to be taught in both English and Chinese.
The reason why I say it is that our English is not to good,if it is only in English,we can't understand all,thougt it can improve our Listen and Speak skills.For example,the student whose English is too bad,he couldn't understand something,he want to ask what he don't know,but for his English leve,he has no courage to ask,though the English teacher explain it .
In all,i think our English class should in both English and Chinese,it can improve our English mark!
