Now I am monitoring the students taking the second monthly exam, and I am observing them again! Watching them and writing these words. A girl, with long, straight, central-parted hair, is gently touching her upper lips while pondering the questions. Another girl, who has a nickname “baby,” looks serene while working on the papers. Still, another girl, with her elbow rested on the desk, is writing on the exam paper earnestly. This is a history exam, which is not very difficult, I guess. Even I can work out the answers to some questions myself. How do you know the exam is easy? Some boys’ heads have rested on the desk for quite a while. I guess they must be exhausted, after a day’s exam. Luckily, the weekend is coming up, and there is no courses on this Saturday! Good for students, and also myself.Looking at the students’ faces, I wonder how heavy burden the study has brought to them, with their life loaded with so many exams and classes. With such a tight schedule, how could they have time to browse the abundant books in the library? How would they have time to breathe for a while, to expose themselves to another world unfolded by books, I mean, no textbooks. “Muss es sein?” (Must it be so?) said so by Beethoven in his late life. I hope the answer is not “Es muss sein!” (It must be so).
