If you did do all 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 (あ) 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 Mr. Woodall expected to see answers (1) which were connected to the own good of the students, but (3) he was wrong. The majority of the which he received from his students were for the good of answers (5) others. 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." Apparently, many of the students regretted saying something (5) ( ) hurt their friends and wanted to change that. Surprisingly, close to 40% of the students answered this way. Another common answer was about pets. “(6) 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. turn back (時計を) 巻き戻す pleasantly 心地よく expected to 〜するだろうと思う good 利益 majority 大多数。 大部分 take back 取り消す apparently どうやら~らしい close to ~近く be nice to 〜にやさしい junk food ジャンクフード concern for 〜への気遣い。 配慮 )に適切な語を入れなさい。 問1 ), (5) ( (1) (were ) (5) ( that ) 問2 下線部(2) は具体的にどのような能力ですか。 日本語で答えなさい。 ( 問3 「下線部(あ)~(う)の which のうち, 他と用法の異なるものを1つ選び, 記号で答えなさ い。 ( う ) 問4 下線部(3) の内容を具体的に説明した次の文の( )に適切な日本語を入れなさい。 回答は( 大部分は ( に結びつくものと予想していたが, だった。 問5 下線部(4), (6) を日本語に訳しなさい。 (4) (6)
