One day a rich man took his son on a trip to the country. He wanted to show his son how the poor lived, so he could be thankful        his wealth.
They spent a couple of days and nights on the farm of        would be considered a very poor family.
On their return the father asked his son     (explain) what he had learned. The boy, who had remained silent and deep in thought on the journey home,      (reply) in a way that shocked his father.
The boy said he wanted to become a farmer. He envied the farmers who had the beautiful night stars to give them light      his family had only expensive lanterns(台灯). His wish was to have a farm          he could go swimming in an endless river instead of the garden pool in their home. Finally he asked his father, “ what makes us     (safe), large walls around our house or friends that will protect us?”
The boy finished by saying, “     the trip T thought we were rich but today I learned who is truly rich.” with this the boy got up and walked away,     (leave) his father sitting on their comfortable sofa, totally          (speech).
