答案：C
During my second year of middle school, our teacher gave us a test. I studied hard and __46 well in all the subjects, so the questions were not difficult for me. 47 I stopped when I read the last one：“What is the 48 of the woman that cleans the school?” Of course this was a joke. I saw the cleaning woman every day. She was short and about 60 years old. She had dark hair. But 49 would I know her name? I had never talked __50 her before. In fact, I had never even thought about talking to her. I started to feel rather guilty(惭愧的).Finally, I 51 my paper, without finishing the last question. Before the class ended, one student asked, “Will be last question count(计入) toward __52 grade?” “Of course,” the teacher said, “In your life, you will meet many people. All are important. They deserve(值得) your attention and care, even if you just 53 and say hello to them.” I’ve never forgotten that 54 _. I should get to know all of the people who work and live around me. That was, perhaps, the most 55 lesson of my life. Later, I learned that the cleaning woman’s name was Dorothy.
