Tom，Dick and Sam are all middle school students in New York.This summer holiday，they went to visit their uncle in London by air.Their uncle and aunt were very glad to see them.
On the first day，Tom said to his uncle， "Uncle John，my boys.Let me give you some advice.I have a farm.I farm.I will take you there to have a look.After that，I think you will have an idea."
The farm is very big.Their uncle grew rice，vegetables and a lot of flowers on it.Their aunt showed them her cows，sheep and ducks.The children were very happy to see all these things.Then Tom was going to learn how to plant the vegetables.Dick wanted to learn how to plant the flowers.And Sam was going to learn how to feed the ducks.
They worked hard on the farm.And they were learning fast.A few days later，they could do the work all by themselves.When the holiday ended，the boys had to go home.Their uncle gave them three big boxes.He said "Boys，you work very well here.Here are some presents for you.I think you will like them."
After they got home，they opened the boxes.There were some nice vegetables in two boxes and in the third one，there were four big fat ducks.
