Vocational students usually have poor basic skills in English. The reason is that most of the students lived in remote villages, counties, towns in China. The atmosphere of English learning in these areas is not as good as that in cities, and English teaching levels and teaching resources are limited there. When they speak English, their expressions are sometimes affected by Chinese seriously. The sentence structures of Chinese will appear in their English sentences frequently. This phenomenon, in the field of second language acquisition of linguistics, is called language transfer. Linguists have paid close attention to this learning state. There are two cases of language transfer: positive transfer and negative transfer. Most of vocational students are beginners of English and they are affected by Chinese transfer easily. Taking vocational students as the research object, this article studies and analyzes the influence of Chinese on English learning, hoping to help the students take advantage of the positive transfer, and avoid the negative transfer of Chinese on their English.
