6、r答案解析：文章大意：本文主要講述的是關(guān)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 tendtend 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(jù)前后語意，填入negative最為恰當(dāng)，表示少的睡眠時間對大腦的活動有負(fù)面的影響。3.

F definitely作者在首段已經(jīng)提出這個觀點是一個myth，那么顯而易見最后一段中出現(xiàn)的myth是作為一種強調(diào)手段，應(yīng)填入definitely；8. O younger空格的前面是 when they were， 當(dāng)他們年輕的時候；應(yīng)填入younger；9. E continuing本
