"The ability to sleep in one chunk (整塊時間) overnight goes down as we age but the amount of sleep we need to __6__ well does not change," Dr Drummond told the American Association for the Advancement of Science conference in San Diego.

　　"It's __7__ a myth that older people need less sleep. The more healthy an older adult is, the more they sleep like they did when they were __8__. Our data suggests that older adults would benefit from __9__ to get as much sleep as they did in their 30s.

　　[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：本文主要講述的是關于老年人睡眠的問題：是否老年人與年輕人相比只需要較少的睡眠時間?

　　1. N tend tend to 固定搭配;表示"傾向于;"符合句意;

　　2. L negative 空格后是effect， 前面是a(n)， 由此可見，該處需要填入一個形容詞;題目給出的形容詞有negative, sufficient, younger;根據前后語意，填入negative最為恰當，表示"少的睡眠時間對大腦的活動有負面的影響。"

　　3. H efficiently 根據推測，該處應該填入一個副詞，題目給出的副詞有efficiently, definitely, formally;前面提到，老年人在睡覺的時候更容易被打斷，而后面用while提出一個對比的概念，年輕人相比起來能獲得更_______ 的睡眠;綜合起來，選用efficiently(最有效率的)最為準確。

　　4. B associated be associated with 固定搭配;表示"與…聯系在一起";本句話表示"更多的睡眠通常都與健康度聯系在一起";

　　5. A alert 先看整句話的含義，"如果他們能睡更長的時間，他們的感覺應該會更好以及…"那么，該處應該填入一個褒義詞，選擇alert比較恰當，表示"更加警覺，機靈";

　　6. J function 根據判斷，此處應該填入一個動詞，剩下的動詞有cling, function;整句話的意思是"當我們上了年紀的時候，我們一覺睡到天亮的能力下降了，但是，我們需要…的睡眠量并沒有改變;"空格后的單詞是 well， cling 在這里并不合適，一般與to連用;選用function 最為適合;

　　7. F definitely 作者在首段已經提出這個觀點是一個myth，那么顯而易見最后一段中出現的myth是作為一種強調手段，應填入definitely;

　　8. O younger 空格的前面是 when they were…， "當他們年輕的時候";應填入younger;

　　9. E continuing 本句的意思是"我們的數據顯示老年人將從…獲益;"空格的后面是"得到和他們在三十多歲的時候能得到的睡眠一樣多";根據上下文意思，該處應填入"continuing";

　　10. G different different from 固定搭配;表示"和…不同"。
