i think the most improtant thing is communication not accent or grammar i do not know the persons who read this article will agree with me on this point. i think for a student who are trying to master a language,if he or she wanna know how to speak ,the most important is open his or her mouth. i have seen many people in China are too shy to speak.they are afraid of their grammar is wrong and their accent is not native. In my opinion, spoken language is very different from written language.Its requirements of the largest is communication. No one can avoid making mistakes ,espacially non-native speaker. So,i think ,to spoken language ,only through exercising,can we improve. Do you agree with me ?
