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.

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.
