单选题Is teaching important? Well, of course it is. There was a time when the necessary knowledge could be taught to the young by family members. But as societies became more complex and division of labor more common, it was impossible for family members to teach the information and skills young people needed to become useful members of the society. As the need for specialists appeared, the job of teaching came into being in our country, and teaching as a job has been of increasing importance over the past hundred years. Today, we have strict rules for teachers. We hope all children can attend schools. Many things tell us that teaching is indeed an "important" job. In recent years, there has been an increasing need for teachers to be "responsible". This means that the public expects teachers to succeed in teaching important information to the young. Teachers' salaries today, while not much, certainly are much higher than they were in years past. These increases have come about because people have realized that without enough salaries, people who have abilities will not become teachers. Today almost no one says that "anybody will do" for a teacher. The public expects "quality people" to teach the young, and progress is being made to give salaries that will make people who have abilities become teachers.

单选题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 every 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 has something to do with a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.
