      One pleasant New Year morning，Edward rose and washed and dressed himself very quickly.He wanted to be the first to wish everyone a happy New Year.He looked in every room，and shouted the words of welcome.He ran into the street to repeat them to those he might meet.When he came back，his father gave him two bright new silver dollars.His face lighted up as he took tjye.aim.He had wished for a long time to buy some pretty books that he had seen at the bookstore.
      He left the house with a light heart，intending to buy the books.As he ran down the street he saw a poor German family，the father，the mother，and three children shivering（颤抖）with cold.
      "I wish you a happy New Year，" said Edward，as he was happily passing by.The man shook his head. "You do not belong to this country？" asked Edward.The man again shook his head，for he could not understand or speak the English language.But he pointed to his mouth，and to the children，as if to say， "These little ones have had nothing to eat for a long time." Edward quickly understood that these poor people were in a very difficult situation and required some jye.ailp.He took out his dollars，and gave one to the man，and the other to his wife.
      How their eyes sparkled（闪耀）with gratitude!They said something in their language，which doubtless meant， "We thank you a thousand times，and will remember you in our prayers."
      When Edward came home，his father asked what books he had bought.He hung his head for a moment but quickly looked up. "I have bought no books，" said he， "I gave my money to some poor people，who seemed to be very hungry."

      "I think I can wait for my books till next New Year，" continued he.__________.

      Hearing what his father said and holding the books his father gave him in his arms，Edward felt he was the happiest boy in the world.__________.
