Though there are many differences between English and Chinese, many rules are shared by English and Chinese, especially in terms of grammar. Therefore, in teaching of English grammar, proper use of transfer of Chinese grammar may help the learners learn English. This paper introduces Chinese positive transfer and negative transfer in learning English grammar, and discusses how to make use of Chinese transfer to improve English teaching.展开更多
