问题     每年国内外都有各种不同的大学排行榜出炉,为学生择校或评价大学作参考。排行体系非常全面,它不是在一个维度上比较大学,而通常是使用一个算法(algorithm),把一所大学所要评价的变量,例如师资、科研成果、名声等转换成排行榜上的一个数值。问题是,不同排行榜对所选变量给予不同的权重,所以导致不同的结果。排行取决于那些变量以及所赋予的权重。

选项

答案 Every year, there have emerged a variety of college ranking lists at home and abroad, which function as reference materials for students’ selection and assessment of colleges and universities. The ranking system is so inclusive that it does not compare colleges and universities but usually transforms all the evaluation variables such as faculty, research fruits and popularity into a value in the ranking list by using an algorithm. The problem is that different ranking lists give different weights to the chosen variables, thus resulting in different results. Ranking depends on those variables and the given weights.
