Student participation（参与）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.In graduate discussions the professor has a"manager"role and the students make presentations and lead discussions.,The students do the actual teaching in these discussions.
A professor′s teaching method is another factor（因素）that determines the degree and type of student participation.Some professors prefer to control discussion while others prefer to guide the class without controlling it.Many professors encourage students to question their ideas.Students who object to the professor′s point of view should be prepared to prove their positions.
In the teaching of science and mathematics,the controlling mode of instruction is generally traditional,with teachers presenting formal lectures and student staking notes.However,new educational trends have turned up in the humanities and social sciences in the past twenty years.Students in education,society,and history classes,for example,are often required to solve problems in groups,design projects,make presentations,and examine case studies.Since some college or university courses are"practical"rather than theoretical,they pay more attention to"doing"for themselves.

About 35%of all high school graduates in America continue their education in an institution of higher learning.The word college is used to refer to either a college or a university.These institutions offer four-year programs that lead to a Bachelor of Arts(B.A.)or Bachelor Science(B.S.)degree.Some students attend a junior college(providing only a two-year program)for one to two years before entering a four-year college as a sophomore(二年级生)or junior(三年级生).
It is generally easier to be accepted at a state university than at a private one.Most private schools require strict entrance examinations and a high grade point average(GPA),as well as specific college prep classes in high school.Private schools cost considerably more than state colleges and famous private schools are very expensive.Poorer students can sometimes attend,however,by earning scholarships.Some college graduates go on to earn advanced masters or doctoral degrees in grad(graduate)school.Occupations in certain fields such as law or medicine require such advanced studies.
Since college costs are very high,most students work at part-time jobs.Some have full-time jobs and go to school part-time.Often some will take five or more years to complete a four-year program because of money/job demands on their time.
While the college and work demands take up the great part of a student’s time,most still enjoy social activities.Sports,dances,clubs,movies,and plays are all very popular.However,gathering together for long,philosophical talks at a favorite meeting place on or near the university is probably the most popular activity.
College education is_______in America.

A.quite common
B.very rare
C.something difficult
D.almost impossible
