If you Do you ever wish you (1) had (2) that ability, maybe you would spend more time practicing soccer, learn the instrument that you always wanted to play, study harder for that big test, or try to save more money for the future. 2 What would you do if you had the ability to turn back the clock? This was a question which Mr. Woodall, a high school teacher in Philadelphia, asked his students. Mr. Woodall wanted to know what was important to his students but was pleasantly surprised to see the results. I think their answers will be very interesting to you, too. (3) 3 Mr. Woodall expected to see answers (which were connected to the own good of the students, but he was wrong. The majority of the answers (5)which he received from his students were for the good of others. 4 Targ ①関係 2157 (4) A very common answer he found was, “If I could turn back the clock, I would take back some things that I said to a friend."

"If I were able to turn back the clock, I would spend more time with my dog," or "(7)I would be nicer to my cat," were some common answers. Almost 25% of the students missed their pet very much and wanted to show more love. These pets included dogs, cats, birds, rabbits and other animals. 6 There were other answers about reading more books, studying harder, or eating less junk food. However, Mr. Woodall was quite impressed with his students and their concern for others. He decided to share all of the answers with his students, and the students enjoyed hearing the different answers. Mr. Woodall decided to try this activity with his students every year. By asking, he felt he would learn a lot about his students. tu P e g n t
