"The ability to sleep in one chunk (整塊時(shí)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. That's __10__ from person to person, but the amount of sleep we had at 35 is probably the same amount as we need at 75."

　　[B] associated

　　[C] attracting

　　[D] cling

　　[E] continuing

　　[F] definitely

　　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(wèn)題：是否老年人與年輕人相比只需要較少的睡眠時(shí)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(jiàn)，該處需要填入一個(gè)形容詞;題目給出的形容詞有negative, sufficient, younger;根據(jù)前后語(yǔ)意，填入negative最為恰當(dāng)，表示"少的睡眠時(shí)間對(duì)大腦的活動(dòng)有負(fù)面的影響。"

　　3. H efficiently 根據(jù)推測(cè)，該處應(yīng)該填入一個(gè)副詞，題目給出的副詞有efficiently, definitely, formally;前面提到，老年人在睡覺(jué)的時(shí)候更容易被打斷，而后面用while提出一個(gè)對(duì)比的概念，年輕人相比起來(lái)能獲得更_______ 的睡眠;綜合起來(lái)，選用efficiently(最有效率的)最為準(zhǔn)確。

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

　　5. A alert 先看整句話的含義，"如果他們能睡更長(zhǎng)的時(shí)間，他們的感覺(jué)應(yīng)該會(huì)更好以及…"那么，該處應(yīng)該填入一個(gè)褒義詞，選擇alert比較恰當(dāng)，表示"更加警覺(jué)，機(jī)靈";

　　6. J function 根據(jù)判斷，此處應(yīng)該填入一個(gè)動(dòng)詞，剩下的動(dòng)詞有cling, function;整句話的意思是"當(dāng)我們上了年紀(jì)的時(shí)候，我們一覺(jué)睡到天亮的能力下降了，但是，我們需要…的睡眠量并沒(méi)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(jīng)提出這個(gè)觀點(diǎn)是一個(gè)myth，那么顯而易見(jiàn)最后一段中出現(xiàn)的myth是作為一種強(qiáng)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(shí)候";應(yīng)填入younger;

　　9. E continuing 本句的意思是"我們的數(shù)據(jù)顯示老年人將從…獲益;"空格的后面是"得到和他們?cè)谌鄽q的時(shí)候能得到的睡眠一樣多";根據(jù)上下文意思，該處應(yīng)填入"continuing";

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

In Afghanistan, Bosnia, and Colombia, however, groups of children have been taking part in peace education __1__. The children, after learning to resolve conflicts, took on the __2__ of peacemakers.

　　答案解析：

　　1. 【答案】 K

　　【精析】 名詞辨析題。根據(jù)句意，空格處缺少名詞，意為"活動(dòng)，項(xiàng)目"。 H)images意為"影像，圖像";O)victims 意為"受害者"，均與句意不符。

　　2. 【答案】 M

　　【精析】 名詞辨析題。空格位于定冠詞the之后，介詞of之前，缺少名詞，與took on the...of搭配，因此選M)role"角色"。A)acting 意思接近句意，但是不能和took on the...of 搭配。

　　3. 【答案】 A

　　【精析】 動(dòng)詞辨析題。空格句謂語(yǔ)動(dòng)詞為studied，因此as peacemakers作主語(yǔ)Groups of children的定語(yǔ)，as意為"是，作為"。此處應(yīng)用現(xiàn)在分詞作定語(yǔ)，選項(xiàng)中的另一個(gè)現(xiàn)在分詞為B)assuming意為"假設(shè)"，不符合句意。

　　4. 【答案】 J

　　【精析】 動(dòng)詞辨析題。空格處缺少謂語(yǔ)，直接賓語(yǔ)為opportunities，需要及物動(dòng)詞。答案只能選offer。

　　5. 【答案】 D

　　【精析】 形容詞辨析題。空格處單詞作ones的定語(yǔ)，與peaceful并列，意義應(yīng)該與angry相反。cooperative 意為"合作的"。 C)comprehensive意為"理解的，廣泛的"，意義不符。

　　6. 【答案】 G

　　【精析】 副詞辨析題。空格位于take a step之后，介詞toward之前，需要副詞。孩子需要向前邁進(jìn)一步成為和平締造者。take a step forward"向前邁進(jìn)一步"。 L)respectively意為"分別地"，意義不符。

　　7. 【答案】 F

　　【精析】 副詞辨析題。空格位于be動(dòng)詞與表語(yǔ)useful之間，需要副詞修飾useful。especially符合題意。

　　8. 【答案】 I

　　【精析】 名詞辨析題。空格處需要名詞，意義與resources 或者teachers 并列。image為名詞，看似與resources并列，但意義不如information恰當(dāng)。

　　9. 【答案】 O

　　【精析】 名詞辨析題。空格位于定冠詞the之后，介詞of之前，缺少名詞，要幫助的應(yīng)該是孩子--戰(zhàn)爭(zhēng)的受害者。

　　10. 【答案】 E

　　【精析】 形容詞辨析題。空格位于定冠詞the之后，名詞school之前，缺少定語(yǔ)。根據(jù)文章意思，先在一個(gè)班級(jí)創(chuàng)建和平締造者俱樂(lè)部，然后擴(kuò)展到其他班，最后影響到整個(gè)學(xué)校的文化氛圍。entire"整個(gè)"符合題意。

　　I hesitated. How would I, unable to speak the language, __3__ unfamiliar with local geography or transportation systems, set up __4__ and do research? It seemed impossible, and with considerable __5__ I sat down to write a letter begging off. Halfway through, a thought ran through my mind: you can't learn if you don't try. So I accepted the assignment.

　　There were some bad __6__. But by the time I had finished the trip I was an experienced traveler. And ever since, I have never hesitated to head for even the most remote of places, without guides or even __7__ bookings, confident that somehow I will manage.

　　The point is that the new, the different, is almost by definition __8__. But each time you try something, you learn, and as the learning piles up, the world opens to you.

　　I've learned to ski at 40, and flown up the Rhine River in a __9__. And I know I'll go on doing such things. It's not because I'm braver or more daring than others. I'm not. But I'll accept anxiety as another name for challenge and I believe I can __10__ wonders.

　　【精析】 動(dòng)詞辨認(rèn)題。空格處缺少動(dòng)詞原形。根據(jù)句意，意為"聲稱"。 D)claim比較隨意，可以表示"個(gè)人的聲明，宣稱";claim to do表示"宣稱做某事"。A)accomplish"完成";F)declare"宣布(法律、公告等)，聲明";M)regret"遺憾，抱歉"，詞義 不符。

　　2. 【答案】 H

　　【精析】 句法推斷題。空格位于系動(dòng)詞was之后，介詞to之前，因此缺少形容詞或者過(guò)去分詞，可用于be...to 的搭配。be limited to表示"局限于"。 L)reduced表示"減少"，不能與to搭配。

　　3. 【答案】 O

　　【精析】 副詞辨認(rèn)題。用于形容詞之前，空格處缺少副詞。根據(jù)句意，表示"完全地"。選項(xiàng)中的另一個(gè)副詞E)constantly"經(jīng)常地"，不符合句意。

　　4. 【答案】 G

　　【精析】 名詞辨析題。空格處缺少名詞，與research并列，因此選擇G)interviews"采訪"。選項(xiàng)中的另三個(gè)名詞C)balloon"氣球"， J)moments"時(shí)刻"， K)news"新聞，消息"，不符合句意，排除。

　　5. 【答案】 M

　　8. 【答案】 N
