Passage 3
One day I said that I would go abroad for further studies after my college education.My decision evoked(引起)the objection of my family:Why should I borrow a huge sum of money for overseas studies while I might receive the same education at home at a relatively low cost? My answer is:In addition to knowledge,I can gain experience that those who stay at home will never have.
First,experience is the opportunity for the real-life use of foreign languages.There is no better opportunity to improve second-language skills than living in the country in which it is spoken.
Second,living and studying abroad offers me a different perspective on the world.On a university campus, foreign students are likely to meet their counterparts(对应的人或物)from different countries and areas and be exposed to different ideas and values.This helps to have a better understanding of different societies and inevitably sees my own country in a new light.
Third, overseas experience may be frustrating and painful, but it is helpful at the same time.A person going abroad for study often experiences much more difficulties.Yet, the difficulty, with the frustration(沮丧)brought on by culture shock, is a rewarding experience for one's future life.
Although going abroad is expensive and perhaps painful, the payoff is worthwhile.For the benefit is not merely knowledge gained, but the experience desirable in one's personal life.

In the author’s opinion, what is the advantage of going abroad?
