My Views on University Ranking
参考答案:My View on University Ranking
In recent years, all kinds of University Ranking Lists can be found on some educational websites, or newspapers. The ranking standards also vary. These lists have great influence on students. They are even becoming the only scale to evaluate the colleges and universities.
People hold different views toward this phenomenon. Some believe that these lists help the students a lot, especially for those who will choose their university. While some other protest vigorously. In their points, the list is really ridiculous and harmful. In my view, the university ranking may have its own reference values, but its disadvantages overweigh its values.
For those university-students-to-be, they are supposed to choose the school according to his or her own situation, but not the so-called Ranking List. What’s more, how about the university students How do they feel about themselves when they see the ranking The list may become some intangible shackles for them if their own school ranks poorly.
In a nutshell, there is no easy method to rank these universities, but the Ranking, only helps students ignore the essentials, namely, their ninety-nine percent perspiration.
