参考答案
正确答案：B
解析：本题为推理题，问“第一段暗含了什么意思”。第一段最后一句话提到“…people who routinelysleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke—probably as a result of an underlying disorder that keeps them from snoozing(睡)soundly．”意思是那些每天习惯睡八个小时以上但仍然感觉疲劳的人死于中风的危险是普通人的三倍，这也许就是一种潜在的紊乱导致的结果，正是这种紊乱才让他们难以安馋。由此句可以看出潜在的紊乱可能导致人们睡眠质量不高，虽然睡眠时间长，但仍然感到疲惫。因此B“睡眠质量不高可能是身体紊乱的征兆”为正确项。
