One Sunday afternoon a young man came to visit my friend. He stayed a long time. He talked and talked. Soon it was time for my friend to take Jack for a walk. But the visitor still stayed.

答案：
(答案→)B
解析：这篇短文中作者主要讲述了他朋友的一只警犬和其主人的故事，每周日下文狗主人都会带它去公园散步，但一次主人朋友的到访延迟了主人带狗散步的时间，结果这只警犬把主人朋友的帽子叼走了。
【小题1】细节理解题。根据短文第二段He stayed a long time. 可知，这个年轻小伙子的确在主人家呆了很长时间，所以答案应为Yes，he did.，A项的结构错误，故选B。
【小题2】细节理解题。根据第二段Soon it was time for my friend to take Jack for a walk. 可知，它希望主人带它去公园散步，故选A。
【小题3】细节理解题。根据文中But the visitor paid no attention to Jack. 一句可知，这个年轻小伙子光顾着和主人说话了，但是没有注意到这只警犬的异常举动，故选D。
