52. 根据判断，此处应该填入一个动词，剩下的动词有cling, function;整句话的意思是"当我们上了年纪的时候，我们一觉睡到天亮的能力下降了，但是，我们需要…的睡眠量并没有改变;"空格后的单词是well，cling 在这里并不合适，一般与to连用;选用function 最为适合;
53. 作者在首段已经提出这个观点是一个myth，那么显而易见最后一段中出现的myth是作为一种强调手段，应填入definitely;
54. 空格的前面是 when they were…， "当他们年轻的时候";应填入younger;
55. 本句的意思是"我们的数据显示老年人将从…获益;"空格的后面是"得到和他们在三十多岁的时候能得到的睡眠一样多";根据上下文意思，该处应填入"continuing";
