[A]alert

[B]associated

[C]attracting

[D]cling

[E]continuing

[F]definitely

[G]different

[H]efficiently

[I]formally

[J]function

[K]mixed

[L]negative

[M]sufficient

[N]tend

[O]younger

答案解析：

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?

1.Ntendtendto固定搭配;表示"倾向于;"符合句意;

2.Lnegative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。"

3.Hefficiently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。

4.Bassociatedbeassociatedwith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";

5.Aalert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";

6.Jfunction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;

7.Fdefinitely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;

8.Oyounger空格的前面是whentheywere…，"当他们年轻的时候";应填入younger;

9.Econtinuing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";

10.Gdifferentdifferentfrom固定搭配;表示"和…不同"。
