　　“We can do a lot for others with all the money,” John said with a smile.“But who shall we help?” Linda asked.“Let’s help our neighbors,Billy and his sister,Rose.I have found that there are some holes in their shoes,” John said.“We could buy some new shoes for them,” Linda said.
　　Linda and John told their mother their plan.She was glad and took them to a shoe store at once.Linda picked out a pair of shoes for Rose.John picked out a pair of shoes for Billy.They put the two pairs of shoes into two beautiful boxes.When it was darker,John walked to Billy and Rose’s house quietly.He put the boxes near the door,and knocked hard,and then he ran away quickly.
　　Billy and rose came out.“Look!There are presents for us.Someone left them here,” Billy said.They looked around,but they couldn’t find anyone.They took the boxes inside happily.
