When you go to university to study for a degree, you have decided to study professionally, rather than as an amateur; so being a student is now your profession for at least the next four years.

This involves a change of attitude in many ways. Although the process has been going on since you went to middle school, the biggest change is going to take place. Now, instead of taking several subjects, you have chosen one major subject because you find it interesting and worth exploring further. The choice was yours. You also have the goal of getting a degree . The degree and the stages you have to pass through to achieve it give you motivation, even though it may become weak from time to time, and not all parts of the course will be exciting; a sure way to lose interest is to do too little work. It is a law of diminishing returns - the less work you do, the less interest you will have and the more bored you will become. So, regular work is needed to keep up your interest as well as to keep pace with new work. Another change is in the relationship with teachers. This may well have changed during middle school and high school, but now the whole context is different. You are no longer forced to slay in school all day, and apart from your class time, you organize your own time and place for studying. You are there to study (an active process) rather than to be taught (passive). Your teachers may or may not urge you, but they do want you to share their interest in the subject and they want you to succeed. Some activities, like discussing and reading, are basic to studying. Make sure that you are doing these efficiently. Group discussions give you a chance to train yourself to speak and discuss more effectively. Theywill fail in their purpose if you keep silent—and if you start off this way, the harder it will become to get out of the situation of being the non-speaking member of the group. In the future you are almost certainly going to have to be good at speaking, so get into the way of talking about your subject now. This is actually more fun than sitting being silently miserable because you are not saving anything. Nobody will think what you say is foolish. Everyone will be thankful not to face awkward silence. 55. When does a person start to study professionally？ A）The time when he starts a profession. B）The time when he goes to university.
