阅读理解 Normally a student must attend a number of courses in order to graduate, and each course which he attends gives him a grade which he may count towards a degree. In many American universities the total work for a degree is made up of thirty-six courses each lasting for one term. Generally, a course is made up of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each term. Normally a student would expect to take four years attending two terms each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not done as a regular practice. For e very course that follows a student is given a grade, which is recorded, and the student can get it to show his future employers. All this sets a constant pressure and strain of work, but in spite of this some students still find time for great activities in student affairs. They show much interest in elections to positions in student organizations performed by students who advise the academic authorities (权威人士). Any student who is thought to have broken the rules, for example, by cheating is to appear before a student court. With the large numbers of students, the operation of the system h as something to do with a certain amount of activity.
