An artist went to a beautiful part of the country for a holiday, and stayed with a farmer. Every day he  小题1:out with his brushes（刷子）, and painted from morning to evening. And then when it got  小题2: , he went back to the farm and had a good dinner   小题3: he went to bed. At the end of his holiday, he wanted to pay the farmer, but the farmer said, “No, I don’t want小题4:  . Please give me one of your 小题5: . In a week the money will be used up, but your picture will 小题6:be here.” The artist was very pleased and thanked the farmer for saying such kind of things   小题7: his pictures. The farmer smiled and  小题8: again, “It’s not that. I have a son in London. He wants to  小题9:an artist. When he comes home next month, I’ll show  小题10:your picture. Then he will not want to be an artist any more, I think.”
