A）alertI）formally
B）associatedJ）function
C）attractingK）mixed
D）clingL）negative
E）continuingM）sufficient
F）definitelyN）tend
G）differentO）younger
47.tendto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.beassociatedwith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whentheywere…，“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.differentfrom固定搭配；表示“和…不同”；

[D]complaints[L]psychological
[E]contributions[M]raised

47.raise在这里的意思是“养育”，theenvironmentinwhichyouwereraised意思是“你成长的环境”。

54.indicate意思是“表明，显示”。
全句意为“越来越多的科学（现象）表明基因对人类很多特征有基础作用”。
55.essentially的意思是“实际上，本质上”。
