根据短文内容,从下框的A-F 选项中选出能概括每一段主题的最佳选项.选项有一项为多余项。

1.
There is considerable variety in university classrooms in the United States. Because of diverse teaching
methods and non-standardized curricula (课程), no two courses are the same.    Undergraduate courses
are considerable different from graduate courses. The classroom atmosphere in expensive, private
universities may differ from that in community colleges, which are free and open to everyone.
2.
Participation in the classroom is not only accepted but also expected of the student in many courses.
Some professors base part of the final grade on the student's oral participation. Although there are formal
lectures during which the student has a passive role (i.e., listening and taking notes), many courses are
organized around classroom discussions, student questions, and informal lectures.
3.
Many teachers believe that the responsibility for learning lies with the student. (Courses are not designed
merely for students to pass exams.) The ideal student is considered to be one who is motivated to learn
for the sake of learning, not the one interested only in getting high grades.
4.
Ideally, the teacher-student relationship at universities is characterized by trust. Thus, cheating on tests,
Plagiarizing (抄袭) in written work, presenting other's ideas as original, and turning in homework
completed by someone else are all prohibited (禁止).
5.

Relationships between students in the classroom can be cooperative or competitive. International
students should not hesitate to ask for help if it is needed. in classes where such a grading curve is used,
students may be reluctant to share lecture notes or information for fear that their own grades will suffer.
