第二节 读写任务（共1小题，满分25分）

阅读下面的短文，然后按要求写一篇150词左右的英语短文。

Perhaps you do not know your school principal well. But you might be wise to take him or her seriously. Peking University will enroll students recommended by high school principals this year. Oh November 16, 2009 Peking University released a list of 39 high school principals in 10 provinces who have the chance to recommend students. If the students recommended pass a round of interviews by Peking University, they will have an extra 30 points added to their national college entrance exam scores if they apply to the university after the exam. Peking University said the reason behind the move was a desire to give students with comprehensive and special abilities a chance to stand out.

However, a survey conducted by leading Chinese web portal sina. Com showed 10,046 out of 14,227 people surveyed were against the new idea. Most said the recommendations were unfair on other students. Xue Yong, a Peking University alumni who is now an assistant professor at Suffolk University, told Qianjiang Evening News the experiment could be dangerous if it is abused. But Qu Jun, former deputy director of Shanghai municipal education commission, said the experiment represents much needed change to the existing university entrance system, which had been criticized for years.
