     Tom is a worker in my factory and he is a little bit dirty. I have been taking   1   of him for years and years:
he always wears an old red hat and carries a   2   bag. He usually spends his break time and his lunchtime by
walking around to   3   the unused tins around.
     Once I saw him by his   4   ,with a lot of rubbish bags, which were full of aluminum (铝) tins. He threw
them into the back of his car and then   5   the car. Being very curious, I got into my car to   6   him. He drove 
  7   he reached the entrance to a wide, empty parking area, but did nothing more.
     Today, I was   8   one of the broken machines during lunchtime when this "tin man" came along with his
bag. As usual, he   9   the tins around the place. My   10   ,who was worried about how the   11   caused by
the machine would affect production, was standing there watching me.
     When I finished my job, my manager asked the"tin man" about what he would   12   the tins that he had
collected. I had   13   even thought about asking this kind of question,   14   I had always thought that this "tin
man" would sell the   15   to the recycling place. 
      16  ,this "tin man" answered, "I will give them to my neighbor,   17   has epilepsy (癫痫症) and is unable
to work."I was   18   to hear this, and I asked him," you  19   you are collecting all those tins just to help your
neighbor?"
     "I know it doesn't help very much," he said,"   20   try my best to help him."It was the most beautiful
moment in my life and made me feel very humble (卑微的).
