Two brothers were looking at some beautiful paintings. 

　　"Look," said the elder brother. "How nice these paintings are!" 

　　"Yes," said the younger, "but in all these paintings there is only the mother and the children. Where is the father?" 

　　The elder brother thought for a moment and then explained, "Obviously he was painting the pictures." 

　　父亲在哪儿？ 

　　兄弟俩在看一些漂亮的油画。 

　　“看，”哥哥说，“这些画多漂亮呀！” 

　　“是啊，”弟弟说道，“可是在所有这些画中，只有妈妈和孩子。那爸爸去哪儿了呢？” 

　　哥哥想了会儿，然后解释道：“很明显，他当时正在画这些画呗。”
