Nowadays, more and more people have realized the importance of communication in the English class. Through the communication between students and teachers, the knowledge about English language is passed to the learners and the skills of language are practiced and acquired. And the teachers know better about students' performance in English learning. For one thing, through communication, the teacher will obtain useful information about students so as to improve his teaching method and performance. For another, the students can practice spoken English in class more often. They can also ask the teacher's advice on how to improve their methods of English study so that they can master the language more quickly and effectively. In my opinion, since communication in English class is so helpful and beneficial to both the teacher and students, it is better to make efforts to communicate more in class. Through it, the teacher will know what the students want to learn and what problems they meet in English learning and the students can motivate the interest in English learning.
