    The first time I remember noticing the crossing guard was when he waved to me as I drove my son to school. He 16 me with a puzzle ---- all because he waved to me like someone does 17 seeing a close friend. A big, 18 smile accompanied his wave. For the next few days I tried to 19 his face to see if I knew him. I didn’t. Perhaps he had 20 me for someone else. By the time I contented myself with the 21 that he and I were strangers, we were greeting each other warmly every morning like old friends.

    Then one day the 22 was solved. As I 23 the school he was standing in the middle of the road 24 his stop sign. I was in live behind four cars. 25 the kids had reached the safety of the sidewalk, he lowered his sign and let the cars 26. To the first he waved and 27 in 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 28 from the crossing guard, and the driver, a stiff-looking(表情刻板的) businessman, gave a brief, almost 29 wave back. Each following car of kids on their way to school 30 more heartily.

    Every morning I continued to watch the man with 31. So far I haven’t seen anyone 32 to wave back. I find it interesting that one person can make such a(n) 33 to so many people’s lives by doing one simple thing like waving and smiling warmly. His 34 armed the start of my day. With a friendly wave and smiling face he had changed the 35 of the whole neighbourhood.
