He was one of the most intelligent people I’ve ever known.Every Sunday the Philippine Star Newspaper had a special page for word puzzles and among his peers (同龄人), Mr. Filio held the record for solving all the puzzles in less than five minutes. He encouraged me to solve them too and for months and months, I did my best to beat him but failed.Then one Sunday, I did it! I was able to complete them before anyone else. Everyone cheered for me. He came up to me with a smile and said, “No one has ever beaten me before. You’re the first. I’ll have a prize for you tomorrow.” The next day, he gave me a special Scrabble (拼字游戏) set. I would have never been able to afford one like that by myself. Then he said to me, “Kate, what do you think is man’s final goal in life? Happiness, isn’t it? You are happy and that should be considered as a success. Many people spend a lifetime searching for that. Be thankful that you have found it.” I looked at him and knew that my life had changed, probably forever. He must have known that I always felt sad about not having much money. He encouraged me to learn the game and love words. And true to his words, I was never able to beat him again. 小题1:We can learn from the text that Mr. Filio ______.A．was generous to young peopleB．was good at word puzzlesC．lived quite near the restaurantD．won a prize from the Philippine Star Newspaper小题2: The author got a gift because ______.A．Mr. Filio was thankful for her helpB．Mr. Filio was satisfied with her serviceC．she was the first person to beat Mr. FilioD．she was the new record keeper in the restaurant小题3:After she heard what Mr. Filio said, the author probably felt ______.A．amazedB．excitedC．touchedD．inspired小题4:What would be the best title of the text?A．Happiness is also a successB．Interest is the best teacherC．Scrabble makes a differenceD．His words change my life
