Traditionally．universities have carried out two main activities：research and teaching．Many expels would argue that both these activities play a critical role in serving the communi-ty．The fundamental question，however，is how does the community want or need to be served？

In recent years universities have been coming under increasing pressure from both the govemments and the public to ensure that they do not remain…ivory towers”(象牙之塔)of study separated from the realities of everyday life．University teachers have been encouraged，and in some cases compelled，to provide more courses which produce graduates with the techni-cal skills required for the commercial use．If Aristotle wanted to work in university in the uk today，he would have a good chance of teaching computer science but would not be so rea．Dily employable as a philosopher．

A post．industrial society requires large numbers of computer programmers，engineers，managers and technicians to maintain and develop its economic growth but“man”，as the Bible says，“does not live by bread alone．”Apart from requiring medical and social services，which do not directly contribute to economic growth，the society should also value and enjoy litera-ture．music and the arts．In these cost-conscious times，it has even been pointed out in justifi-cation for the funding of the arts that they can be useful money earners．A successful musical play，for instance，can contribute as much to the Gross National Product through tourist dollars as any other things．

In social life，time plays a very important part ineveryday life．In the U．S．A．guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four davs before the party date．But it is not true in all countries．In other areas of the world，it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten．The meaning of time differs in dif-ferent Darts of the wodd．Thus，misunderstandings arise between people from cultures that treat time differentlv．Promptness is valued highly in American life．If people are not prompt，they may be regarded as impolite or not fully responsible．In the U．S．no one would think of keep-ing a business associate waiting for an hour，it would be too impolite．A person who is 5 mi-nutes late．he wm say a few words of explaination，though perhaps he will not complete the sentence
