For the past two years, I have been working on students’ evaluation of classroom teaching. I have kept a record of informal conversations __71__ some 300 students from at __72__ twenty-one colleges and universities. The students were generally __73__ and direct in their comments __74__ how course work could be better __75__. Most of their remarks were kindly __76__—with tolerance rather than bitterness—and frequently were softened by the __77__ that the students were speaking __78__ some, not all, instructors. Nevertheless, __79__ the following suggestions and comments indicate, students feel __80__ with things-as-they-are in the classroom.
    Professors should be __81__ from reading lecture notes. “It makes their __82__ monotonous (单调的).”
    If they are going to read, why not __83__ out copies of the lecture? Then we __84__ need to go to class. Professors should __85__ repeating in lectures material that is in the text-book. “__86__ we’ve read the material, we want to __87__ it or hear it elaborated on, __88__ repeated.” “A lot of students hate to buy a __89__ text that the professor has written __90__ to have his lectures repeat it.”
