"Look, Mum! See what a pretty fish! It is a little trout(鳟鱼)," said Scott to his mother. Scott's mother asked, "Where did you get it, Scott?"
"Jim caught it in the small river. When I went to the small river to get some water this morning, I saw this little fish. Then I told Jim about the fish, and he ran to get his fish net(网). He put the net into the water and caught it, and then I put it into this glass."
"Well, what will you do with it?" asked Scott's mother.
"I will keep it, Mum," answered Scott.
"But, my boy, it will not live in that glass. You should put it back into the small river," said his mother.
Scott was a little sad. "I wish I could keep it. It is so pretty! May I keep it?"
"No, Scott," said his mum. "You must put it into the small river. A trout will not live in warm water."
