The first time I remember noticing the crossing guard was when he waved to me as I drove my son to school. He 31 me with a puzzle—all because he waved to me like someone does 32 seeing a close friend. A big, 33 smile accompanied(伴随) his wave. For the next few days I tried to 34 　his face to see if I knew him. I didn’t. Perhaps he had 35 me for someone else. By the time I contented myself with the 36 that he and I were strangers, we were greeting each other warmly every morning like old friends.

Then one day the 37 was solved. As I 38 the school he was standing in the middle of the road 39 his stop sign. I was in the line behind four cars. 40 the kids had reached the safety of the sidewalk, he lowered his sign and let the cars 41 . To the first he waved and 42 just the same way he had done to me over the last few days. The kids already had the window down and were happily waving their reply. The second car got the same 43 from the crossing guard, and the driver, a stiff- looking (表情刻板的) businessman, gave a brief,（简洁的） almost 44 wave back. Each following car of kids on their way to school 45 more heartily.

Every morning I continued to watch the man with 46 . So far I haven’t seen anyone 47 to wave back. I find it interesting that one person can make such a 48 to so many people’s lives by doing one simple thing like waving and smiling warmly. His 49 armed the start of my day. With a friendly wave and smiling face he had changed the 50 of the whole neighborhood.
