Do you agree or disagree with the following statement? Teachers should be paid according to how much their students learn. Give specific reasons and examples to support your opinion.
参考分析：
不能同意。乍看起来(at the first glance)很有道理。问题在于：
教育不是商品。
如何保证能够确切地衡量学生究竟学到了多少？
学生学到多少，并不是老师一个人的事情，还要看学生自身的素质(quality)；能力(capacity)等等。
如果采取了这样的方式，就会出现老师迎合(cater to/ pander to/ play up to students' taste)学生而不是引导(guide; lead)学生，违背了教育的原则。
不同意
（1）无法了解学生到底学了多少东西。考试只是一方面。试题可以出的简单，可以难
（2）有些学生根本就不学习，所以按照这个评判，对教师不公平
（3）对学生压力过大。比如说让学生学很多东西，以便增加薪水。

Teachers' pay
Education is one of the holiest occupations in my view. I disagree with that teachers should be paid according to how much their students learn. Although teachers are important for students, the most important part for learning knowledge is students themselves.
Different teachers has different style, so it is hard to evaluate how well each teacher teaches according to how much students learn. As nobody would have the same character, teachers also have their own teaching styles such as humorous, gentle, strict, to name a few. Maybe some students like humorous teachers, while others prefer a gentle one. But probably the students of a strict teacher could give good results in their study, even though these teachers teach the same thing. We could not say that the strict teacher should be paid higher than the gentle teacher, since we know that the students have learned more because they were afraid.
On the other hand, how much or how well students learn depends on students themselves. In a school, it is easy to see that some students are with high marks, while some others have lower marks. A teacher is a person who direct students how to learn. Students should do much more works. The more attention students pay, the more knowledge they learn. The hard-workers probably get higher scores. Students' learning results depend on individual students' intellectual abilities and the time and energy that they put into learning. Sometimes it has nothing to do what how well the teachers taught. In addition, knowledge that students learn not only comes from the teachers, but also from many sources. Family influence, extracurricular reading and out-class teaching are some of the sources that can provide students with knowledge.
In sum, although teachers are important in students' education and learning, there are many other factors that decide how well students' learn. So it is unfair that teachers are paid according to how much their students learn.
