1. N tend tend to 固定搭配;表示"倾向于;"符合句意;

2. L negative 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. H efficiently 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。

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children __3__ as peacemakers studied human rights and poverty issues in Colombia,

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eventually forming a group with five other schools in Bogotá known as The Schools

function 最为适合; of Peace.

7. F definitely 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 The classroom __4__ opportunities for children to replace angry, violent behaviors

参考译文：

没有书的生活是不完整的生活。书影响生活的深度和广度。它们能够满足人们与生俱来的对自由的渴望、表达的欲望，对创造、对美好生活的愿望。

因此，想获取知识的人必须要有书，而且要有合适的书来满足他们的需要。读者会自然而然地去读书，因为他们对一切东西都好奇，他们渴望分享别人的经历，他们需要从自己受到限制的环境中解脱出来——这一些，都引到他们在书中为自己的精神和心灵寻找食粮。

读者通过阅读寻找生活更深刻的意义，因为书可以让他们既了解过去世界的生活，也了解现在社会的生活。他们可以在书中看到各种各样的人生经历，这样他们便能能够尊重别人的思维方式和生活方式。在建立他们自己的人际关系和对生活做出反应时，读者经常会发现他们读到的故事里的那些人物也有相似的经历，这能够帮他们认清自己的行为，并使之具有意义。 书为人们

3.H “need to do“这是一个很常用的词组，在根据后面的介词 from，因此，这里选H。

4.G

5.N 根据文意，可以判断出是N

6.I 这里需要一个词来组成主语，那么已ing形式作主语+后文的内容，无非就是选I。
