I was in my third year of teaching writing at Ralph High School in New York, when one of m
ystudents, 15-year-old Mikey, gave me a note from his mother. It explained his absence (缺席)from class the day before. "Dear Mr. McCort, Mikeys grandmother, who is eighty years of age, fell down the stairsfrom too much coffee and I kept Mikey at home to take care of her and his baby sister so I could goto my job. Please excuse Mikey and hell do his best in the future. P.S. His grandmother is OK. "I had seen Mikey writing the note at his desk. I said nothing. Most parental-excuse notes Ireceived were penned by my students. If I were to deal with them, Id be busy 24 hours a day. Thewriters of those notes didnt realize that honest excuse notes were usually dull: "Peter was late be-cause the alarm clock didnt go off." The students always said it was hard putting 200 words together on any subject, but when theyproduced excuse notes, they were excellent. So I decided to type out a dozen excuse notes and gavethem to my classes. I said, "Theyre supposed to be written by parents, but actually they are not.true, Mikey?" The students looked at me nervously. "Now, this will be the first class to study the art of the excuse note -the first class, ever, topractice writing them. " Everyone smiled as I went on, "Today Id like you to write An ExcuseNote from Adam to God or An Excuse Note from Eve to God. " Heads went down. Pens racedacross paper. For the first time ever I saw students so immersed (专心的) in their writing, theyhad to be asked to go to lunch by their friends. The next day everyone had excuse notes. Heated discussions followed. But suddenly I saw theheadmaster at the door. He entered the classroom and walked up and down, looking at papers, andthen said, "Id like you to see me in my office." My heart sank. When I stepped into his office, he came to shake my hand and said, "I just want to tell youthat that lesson, that task, whatever the hell you were doing, was great. Those kids were writingon the college level. Thank you." 根据材料请回答下列各 How did the author know that most parental-excuse notes were written by students themselves?
