Hi,everyone. I am new here Hello, everyone, I am newbie here. I am May, a girl from China. I am living in Beijing, capital of China. I graduated from college three years ago. In China, I began learning English from sixth grade. And now English learning begins in third grade. I knew English over ten years. However, I can not speak English at all. Just always use Hello, nice to meet u, bye.... Yesterday, I met a foreign couple who ask me how to go to the subway. I know the way but I do not know how to express myself. I felt so sorry. I can not help them. So I want to learn my English.
