As he was walking back,he saw Grandma's pet duck.23 thinking,he took out the 24 ,shot the duck in the head and 25 it.He knew Grandma loved that duck.She would be very 26 if she knew the truth,he thought.Then he hid the dead duck in the wood pile (堆),only to see his sister Sally 27 .She had seen it all,but she said 28 .
After lunch Grandma said,"Sally,let's wash the dishes." But Sally said,"Grandma,Johnny told me he wanted to help in the 29 today,didn't you,Johnny?" And then she whispered to him,"Remember the duck?" So Johnny did the dishes.
Later Grandpa asked 30 the children wanted to go fishing and Grandma said,"I'm sorry,but I need Sally to help me make supper." But Sally 31 and said,"Well,Johnny told me he wanted to help you." And then she whispered again,"Remember the duck?" So Sally went fishing and Johnny had to 32 at home.
After several days of Johnny doing 33 his work and Sally's,he finally 34 stand (忍受) it any longer.He came to Grandma and said what he had done.Grandma said,"Johnny,I know.You see,I was standing at the window and I saw the whole thing.But because I love you,I 35 you.I was just wondering how long you would let Sally make a slave (奴隶) of you."
