I moved to this small town at the age of twelve.After getting  36   in our new house and starting school,I began to explore the   37  area.I was exploring the pond when I discovered the fish.

There were two of them,one about a foot long,  38  the other just a little smaller,and they were the most beautiful fish I had  39  seen.They had blue and yellow and red  40  from head to tail.Before they saw me,they swam  41  over the sand just under the front edge of the large cedar(杉)tree which had long before fallen  42   the pond.

I went back the next day after school  43   with about six feet of fishing line and a hook borrowed from our elderly neighbor.and half a dozen worms I had   44  out of the garden.We did not own any fishing tool,and   45  a city kid,my fishing experience, had  46  week long visits to my relatives.

I took a shortcut  47  some fallen cedars on my way to the pond.As I was climbing over one tree and ducking under another,I  _48  my footing,and my soup can of worms went flying into the air.My  49   was only increased when I noticed that my worms had disappeared.

I went to the pond,looked down again,and there they were.I made a few  50   to catch them by hand,but I soon realized it was never going to  51 .I had been trying to catch them for quite a while without actually even  52   either one.After each attempt,they   53  suddenly go around the pool,then settle back under the log.They could really go  54 ,but they were just too fast to be caught.I was wet and   55   and it was time to go home.
