一天一个老人到餐馆吃饭，吃完后，对服务员说：“这块牛排为什么没有上周的新鲜！”服务员对老人说：“这块牛排就是上个星期的呀。”
One day an old man went to an restaurant to have dinner. After he finished that meal , he asked the waiter about the reason why this piece of beefsteak was not fresh as the one he saw last week.The waiter said to him:This one is the one you saw last week!
