The members of the third group slept for five hours on weekdays but rested as long as they

22、 wanted on the weekend.”可知，第一组每晚睡9个小时，第二组每晚睡5个小时。第三组的成员在工作日睡5个小时，但是在周末想睡多久就睡多久。所以参与的三组人员的睡眠要求不一样。选项D与文意相符。故选D。2.词句猜测题。根据下文中“ changes to certain body hormones, especially hunger hormones.”可知，某些身体荷尔蒙的变化，尤其是饥饿荷尔蒙。结合and，可以推测，此处与下文在意义上为并列关系，画线词应与changes 意思相近，所以此处指生物钟的改变。选项C符合题意。故选C。3.细节理解题。根据倒数第三段最后一句“Sl
