You are right, but that is all that I can do at present. No English speakers around me, so I never have the chance to speak with them. Besides, I don’t think I have the ability to talk to English speakers now. I have a lot of shortcomings, such as vocabulary and grammar. I think the main work I should do now is listen more, read more, write more and try to speak to myself more. However, thank you for your suggestion about learning English and I will take it as a big concern.
