题型:名词解释

Perhaps you do not know your school principal (校长) well. But you might be wise to take him or her seriously. Beijing University will enroll (招收) students recommended by high school principals this year. If the students recommended pass a round of interviews by Peking University, they will have an extra 30 extra points added to their national college entrance exam scores if they apply to the university.

Beijing University said the reason behind the move was a desire to give students with comprehensive (综合的) or special abilities a chance to stand out.

However, a survey, showed 10,046 out of 14,227 people are against the measure. Some experts agree with the criticism. Liu Daoyu, former president of Wuhan University is one strong opponent(反对者). “There are so many high schools across the country. But only 39 schools are qualified to recommend students. Is it fair to the rest of the schools? Besides, most of the 39 schools are located in big cities, which is unfair to other regions,”

The reform is also unfair to other students, some say. According to Liu, in the competitive exam, one extra point can put a student ahead of a large numbers of others – never mind 30.

“Principals do not know students well. How can they guarantee the recommendation will be fair?” asked Wang Xuming, former spokesman of the Ministry of Education.

The Ministry of Education said the move is a good experiment in college admission reforms and the public should support it even if it is not yet mature (成熟的). It said Beijing University promised a series of supervision (监督) measures to avoid cheating. For example, the information of schools and principals that recommend students, and the recommended students will be put online for a week for public supervision.
