Isn't it wonderful? 这难道不好吗？

"What are you so happy about?" a woman asked the 98-year-old man.   "I broke a mirror," he replied.   "But that means seven years of bad luck."   "I know." he said, beaming,"Isn't it wonderful?"   “你高兴什么？”一个女士问一个98岁的老人。   “我打碎了一个镜子。”他回答。   “但那预示着7年的坏运气。”   “我知道。”他高兴地说，“这难道不好吗？”
