Nowadays, an increasing number of people are concerned about the significance of tertiary education. However, whether the main purpose of the university should be to provide the job-related knowlege to the greduates (graduate) or not is a controversial issue(Using however in this sentence indicates you're comparing it to something, so you should have 'or not' for the comparison). My view is that the sake purpose/role of a universuty is to provide graduates with the knowledge and skills needed in the workplace.
Firstly, it is obvious that the purpose of reason students to received education in collage is to find a decent job in the workplace in the future. This is because most of graduates are faced with enormous stresses in the society,. (Start new sentence here) they need to earn a living and support their families, so, the particular skills is are their real needs in the university.
Moreover, focus on the supply of the job-related knowedge (knowledge) also is a good method to keep the univerity (university) follow on the pace of with the deveopment of the society. For instance, the Alibaba Group was marked as a millstone (milestone) in the e-bussiness area and sparked massive interest in e-bussiness,. if the university puts focus on this area without delay and puts more resources on this industry, the graduates of this collage (college) will be more popular in the workplace and this university also could (could also) keep pace with the world.
That is not to say that the pure academic knowledge is useless,. there are some stdents (students) who really need it to doing some research or study some area in depth, or maybe become a scientist in the future and do more contribution  (contribute more) than others. But unfortunately, this these kind of graduates is are far between. ('few and far between' is the whole phrase normally used.)
In sum summary , the main fumction (function) of the university should be to provide graduates with the knowledge and skills needed in the workplace,. meanwile (new sentence) we can not ignore that the inportance (importance) of the academic knowledge., by doing so, With it, the university could can maintain dynamic and sustainable development.
