There are three reasons to explain my viewpoint.Firstly, campus life is a perfect and precious period to obtain knowledge for undergraduates.Because They have sufficient time to spend in the researching majors which they really interest in. As the research getting deeper, they can acquire more knowledge. Especially they do not need to achieve their targets under great pressure. Secondly, diverse and profound knowledge help students develop and prompt themselves sustainedly. Actually, numerous staffs always feel insecure and difficult to their career. The main reason is that they are lack of deeper knowledges.Finally, undergraduates who have many kinds of knowledge can live better than others.In the modern society, since communication is becoming important day by day, knowledgable individuals can be more easy to solve issues. Overall we acquire knowledge for life, not only for work.
