    Of course this was only a joke.I saw4 cleaning woman every day.She is short and about 60 years old.

    She has dark hair.5 how would I know her name？I have never talked with her before.In fact，I've never even thought about6to her!I stared at my paper.7 guilty I felt! Finally，I handed in my paper，but the last question 8.

    Before the class ended，one student asked the teacher9the last question would count into our grade.

    "Of course，"the teacher said，"In your life，you will meet10 people.It's important for you 11 them.They deserve（值得）your attention and care，even if all you do is just 12 hello."I'll never forget that lesson.Everyone deserves our attention and we13 try to get to know all the people who work and live around us.That was14 lesson of my life.Later that day，I 15that the cleaning woman's name was Dorothy.
