Many years ago,I owned a service station and roadhouse on the main road between Melbourne and Adelaide.
One very cold,wet night at about 3:30 a.m.,there was a   41  on the front door of our house.A young man,wet from    42   to toe,explained that he had    43   out of petrol about 30 km up the road.He had left his _pregnant_（怀孕的) wife and his two children   44  at the car and said that he would _hitchhike_（搭便车) back.
Once I had   45  a can with petrol,I took him back to his car where his two-year-old and four-year-old children were both   46 ,saying that they were cold.Once the car had started,I suggested that he   47  me back.
Before leaving,I had turned the heater   48  in the roadhouse,so that when we went in,it was nice and   49 .While the little ones played and ran   50 ,I prepared bread and butter for the children,and hot chocolate for the   51 .
It was about 5 a.m. before they  52 .The young fellow asked me how much he   53  
me and I told him that the _petrol pump_（加油泵) had   54  $15.He offered to pay “call-out fee”,but I wouldn’t accept it.
About a month later,I received a   55  from Interstate,a large bus company that we bad been trying to   56  to stop off at our roadhouse for a long time.It   57  out that the young fellow I had helped was its general manager,the most   58  person in the company.
In his letter,he thanked me again and   59  me that,from then on,all their buses would stop at my service station.In this   60 ,a little bit of kindness was rewarded with a huge amount of benefits.

The first time I remember noticing 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.
