     Matt and his wife lived in the country. Matt was very mean and hated spending money. One day a

fair(交易会)came to the nearby town.

     They went to the fair and looked at all the things to buy. Matt's wife wanted to buy a hat only costing $28, but was refused. Later on, a comb of $5 attracted her attention, but he would not let her spend any

money.

    Then, in a nearby field, they saw a small airplane. "Fun flight!" the notice said, "$10 for 10 minutes."

     Matt had never been in an airplane and he wanted to go on a fun flight. However, he didn't want to

pay for his wife either. "I've only got $10," he told the pilot. "Can my wife come with me for free?" The

pilot wasn't selling many tickets, so he said, "I'll make a bargain with you. If your wife doesn't scream,

she can have a free flight."

      Matt agreed, and got into the small airplane with his wife. The pilot took off and made his airplane do

all kinds of things. At one moment it was flying upside down.

free."
