　　文章大意：本文主要讲述的是关于老年人睡眠的问题：是否老年人与年轻人相比只需要较少的睡眠时间?

　　47. tend to 固定搭配;表示"倾向于;"符合句意;

　　48. 空格后是effect， 前面是a(n)， 由此可见，该处需要填入一个形容词;题目给出的形容词有negative, sufficient, younger;根据前后语意，填入negative最为恰当，表示"少的睡眠时间对大脑的活动有负面的影响。"

　　49. 根据推测，该处应该填入一个副词，题目给出的副词有efficiently, definitely, formally;前面提到，老年人在睡觉的时候更容易被打断，而后面用while提出一个对比的概念，年轻人相比起来能获得更_______ 的睡眠;综合起来，选用efficiently(最有效率的)最为准确。

　　50. be associated with 固定搭配;表示"与…联系在一起";本句话表示"更多的睡眠通常都与健康度联系在一起";

　　51. 先看整句话的含义，"如果他们能睡更长的时间，他们的感觉应该会更好以及…"那么，该处应该填入一个褒义词，选择alert比较恰当，表示"更加警觉，机灵";

　　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";

　　56. different from 固定搭配;表示"和…不同";

　　总的说来，建议大家在做题之前对所给的所有词汇进行一下简单的词性分类，这样，更有助于考生快速有效地从最小的范围内选出答案。
