Many years ago, there is no way for students to evaluate teachers, for people treat the teachers in a high level, students are in the low level, they are immature. Now, many schools have carried on this practice, I believe such that evaluations are good for both teachers and students.很多年前，学生是不可能有机会评价老师，因为人们觉得老师处在高水平，学生处在低水平，而且也不成熟。现在，很多学校已经实行了这样的制度，我相信评价对学生和老师都有好处。On the one hand, students’ evaluation of the teachers can promote the harmonious environment between teachers and students. Teachers always give students the serious impression, they just like the unchallenging authority. But now, people emphasize the equal relationship in education, which means teachers and students learn from each other. Students can give their opinion to teachers, teachers can improve themselves.一方面，学生对老师的评价可以促进师生间的和谐相处环境。老师总是给学生很严肃的印象，他们就像不可挑战的权威。但是现在，人们在教育方面强调平等的关系，意味着老师和学生互相学习。学生可以把自己的意见讲给老师，老师可以自我提高。On another hand, teachers can benefit from students’ evaluation. In tradition, teachers assess a student from the test, they master a student’s learning level according to the exams, but it is not enough. Students are the major learners, they can evaluate a teacher, letting he know how his teaching method goes, the teacher can adjust his method according to students’ reaction.在另一方面，老师可以从学生的评价中收益。在传统中，老师是通过测试来评估学生，他们通过考试来掌握学生的学习水平，然而这是不够的。学生是学习的主体，他们可以评价一个老师，让他知道他的教学方面如何，老师可以通过学生的反映来调整自己的教学方法。In conclusion, the evaluation about the teachers is beneficial, teachers can know their advantages and disadvantages, they can improve their teaching methods and to create a harmonious learning phenomenon. 总的来说，对老师的评价是有益的，老师可以知道自身的优点和缺点，他们可以提高自己的教学方法和创造一个和谐的教学氛围。
