第二节读写任务(共1小题,满分25分)

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

The generation gap between students and teachers is becoming more significant with only 3.3 percent out of a survey group of 1,000 students from 30 key middle schools in the city saying they would be willing to tell their teachers of their inner thoughts.

In today’s educational environment, teachers are positioned to be the authority figure for learning instead of also becoming good friends in the life of students.

As only students with good marks in exams are considered the “ apples in the eyes” of the teachers, most students think their teachers to be partial (偏心).

“ I feel sad to hear such remarks”, said Yu Yi , a well-known special-class teacher.

She recalled that in the past, teachers and students would play basketball together or comment on the novels while sitting on the grass during a break. But today, study and good marks are the only topics of conversation between students and teachers.

“Schools are not only the place where knowledge is imparted (传授) but also where students are taught how to be an upright person,” Yu said. “The success of a person is not merely determined by intelligence but also by emotional state. ”

Yang Xiong, director of the Juvenile Research Institute, said the educational system which focuses on examinations should be held to be substantially responsible.
