Saving a Dollar 省下1美元

　　　　Johnny: Papa, would you be glad if I saved a dollar for you?
　　Papa: Naturally, my son.
　　Johnny: Well, I have saved one dollar for you. You said that if I brought a good mark this week, you would give me a dollar and I haven’t brought one.
　　Johnny：爸爸，如果我為你省下1美元，你高興不？
　　Papa：當然啦，孩子！
　　Johnny：那好，我省下1美元了。你說過我這個禮拜考出好成績，就會給我1美元。我沒考好！
