The main reason for this situation is that the teachers and students of English majors in some local normal universities have some deviation in understanding the English language. The teachers can not have the right attitude towards English language culture teaching,and they make one-sided emphasis on the skill learning of English language majors,but ignore the normal teaching of professional English language culture. To improve this situation and improve the overall level of English majors in normal univerities, it requires us teachers and students to work together, improving the overall level of this course from the two aspects of ＂teaching＂ and ＂learning＂ , in order to help students to truly grasp the English language culture and skillfully use English in daily life and work.展开更多
