参考解析：

推理判断题。根据第一段的“Places of business that used to keep daytime ‘business hours’ are now open late into the night... A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.”可知，作者说星期日很像星期一是因为现在休息和工作的时间界限已经不清晰了。故选D。
