A man named David went fishing on a holiday．Fishing was his favorite sport，and he had many prizes for fish he had caught．

This summer the weather was beautiful and it was very good for fishing，so he decided to travel around the country，and spent a few days fishing in each of the rivers．

Unluckily, he didn't have much luck，and he caught only a few small fish．He was quite disappointed and was going to go back home when he heard of a large river that was full of fish nearby．   

He found the river quite easily and followed it through the country to a place where it flowed through a farm．He decided to ask the farmer’s permission（许可）to fish in the river．

“You have my permission，”the farmer said；“but you should be careful．For years I stopped my children from going near the river．”

“Is the river dangerous?”David asked．

“It’s not the river，”the farmer said，“it's the fish．They are so big that my children couldn’t hold them．”

David was very excited．All fishermen want to catch really big fish．

“How big are they?”he asked．

“Well．”the farmer told him，“last week I lost one over three feet（英尺）long，and yesterday I lost one just over four feet long．”

“What bad luck．”David said．“I hate losing a big fish once I've caught him．”

“Who’s talking about losing a fish?”the farmer said．“It's two of my children that I lost!”
