题目内容：
62. E To be punctual one has to have self-discipline(自律), and the lack of it affects others. A school boy or girl is unpunctual because he or she does not have the necessary human virtue of self-discipline. It is also a mark of disrespect for a system or an institution. Unpunctual people seldom realise that their habit cause problems to others. A salesman who is not punctual may not make a sale if he arrives late for an appointment. If one is late for a job interview, it is not likely that he will get the job.
