1．学生给老师打分已很普遍；
2．人们对其持不同态度；
3．我的看法
写作导航：第一段宜写高校改革所带来的变化使得学生评价教师很普遍，在有些高校学生的评价甚至成为教师教学好坏的惟一尺度；第二段应写对这一做法，人们有不同的看法，有人，认为学生最有发言权，而有人则反对，认为学生不具备评价教师的素质，对诸如教学材料、教师业务水平等的评价应由教师的同事来完成；第三段写我的看法，我认为，学生评价教师有必要，但要切实做到对教师的教学有帮助，例如可让学生评价在某门课上所学到的知识如何，兴趣如何等等。
范文：
A great change is now taking place in higher education throughout our country. Teachers are being held responsible as nr before for how well they serve their students. It has become as common in colleges and universities for students to grade teachers as for teachers to grade students. In some universities students' rating has n become the only source of information on teaching effectiveness.
This, howr, has caused great controversy. Some are in favor of the rating system. They hold that since students attend the teachers classes ryday, they should have their opinion about their teachers' effectiveness. Others, on the contrary, are strongly against it. They think that students' rating is easy to administer and score, but it also is easy to abuse. They beli that there is much to teaching than what is shown on students' rating forms. Students should not be expected to judge whether the materials used are up to date or how well the teacher knows about the subject. These judgments require professional knowledge, which is best left for the teachers' colleagues.
I think students' rating of their teachers is necessary, but it should be conducted in a way that can really shed meaningl light on teachers' performance. Instead of rating the teachers' knowledge on the subject, students should be asked to estimate what they themselves have leaned in a course, and to report on such things as a teacher's ability to communicate with students, his relationship with students, and his ability to arouse interest in the subject.(英语作文)
