I was on a bus one March evening. The driver didn’t   41  to start the bus soon because it was not yet   42   . A middle-aged woman got on. Tired and sad, she told her story  43  not to anyone in particular. On her way to the station, half of her   44   was stolen. The other half was hidden under her blouse, so she   45  still had some left. A few minutes later, she stopped crying, but still looked   46  .
When all the seats were taken, the driver started the engine. The conductor began to collect fares(车费). When she came to an old man in worn-out(破旧的)clothes, he   47  that he had spent all his money when he had accidentally got on a wrong bus and now he was trying to go home. On hearing this, she ordered the old man to   48   the bus. The old man was almost in tears as he   49   her to let him take the bus home. The driver took the conductor’s side(站在某人一边) and repeated the conductor’s   50   .
The woman was watching the incident.   51    the driver and the conductor raised their voices at the old man, she interfered(干预).
“Stop   52  him! Can’t you see he’s only trying to get home?”
“He doesn’t have any money! ” the driver   53  .
“Well, that’s no   54  to throw him off the bus,” she insisted.
Then she reached inside her blouse, look out her   55   money, and handed it to the conductor. “Here’s his fare and mine. Just stop giving him a   56 time.”
All heads turned to the woman. “It’s only money,” she shrugged(耸肩).
She rode the rest of the way home  57 a happy smile, with the money she’d lost earlier  58  .
On the road of life, the help of strangers can  59 our loads(负担)and lift our spirits. How much sweeter the  60  will be when we make it a little smoother for others!
