示范答案：
Sadly, students would award high marks to teachers who entertained their students and required little work from them. The teachers who really cared about their students and worked them hard for the benefit of the students’ futures might score badly in student opinion surveys. At my university, I had a brilliant lecturer called Professor Hammersley, who would speak without notes and whose lectures showed brilliant insight and often radical interpretation. In student opinion surveys he scored poorly because the students wanted lists they could memorise for exams. Years later, I still look at the notes I was able to take and the ideas are still inspiring.
