Getting to Know the World Outside the Campus
It is indispensable for college students to know what is going on outside the campus. That's because in this “Information Era” the society is developing at such a high speed that we should keep pace with the progress of the outside world. Hence, without knowledge of the outside world, it will be very hard for us to secure satisfying job after graduation; it will be more difficult for us to succeed in the fierce competition.
How to get closer to the outside world? Firstly, we should be well-informed about what is happening around us with the aid of mass media: radios, televisions, newspapers, the Internet, and so forth. Besides, we should do some practical social services so as to cultivate our social skills, broaden our eyesight and enrich our social experience.
As far as I ' m concerned, I plan to know the outside world in two ways: study first to have a good command of knowledge. Next, I intend to get a part-time job to know more about the outside world. Thus, I can apply the knowledge that I have learned at campus to the practical work, which will be helpful in my future
