More sleep in old age, however, is __4__ with better health, and most older people would feel better and more __5__ if they slept for longer periods, he said.
"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.

四級選詞填空習題選項：
[A] alert
[B] associated
[C] attracting
[D] cling
[E] continuing
[F] definitely
[G] different
[H] efficiently
[I] formally
[J] function
[K] mixed

[O] younger
：
文章大意：本文主要講述的是關於老年人睡眠的問題：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"傾向於;"符合句意;
2. L negative 空格後是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;根據前後語意，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，而後面用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…聯絡在一起";本句話表示"更多的睡眠通常都與健康度聯絡在一起";
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…"那麼，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…的睡眠量並沒有改變;"空格後的單詞是 well， cling 在這裡並不合適，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，那麼顯而易見最後一段中出現的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"我們的資料顯示老年人將從…獲益;"空格的後面是"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"。
