Teachers’ appropriate utilization of the evaluation words can make students result in the feeling of the positive thinking and emotion, create a harmonious and interactive teaching atmosphere, and also better reflect the teachers’ teaching quality, teaching wit, the ability of controlling the students in the classroom and even teaching ideas. Therefore, the teachers’ evaluation words have a profound effect on their students. A decent and pleasant evaluation word can make a student remember it all his life, whereas a tingling and insulting evaluation word is enough to leave a student a permanent trauma. So he or she must think twice, make full use of the positive effect of the teacher evaluation words and restrain the negative effect of the teacher evaluation words. 英语课堂评价语的艺术研究(3):http://www.youerw.com/yingyu/lunwen_18553.html
