答案與解析

UNIT3SEAEXPLORATION

第一部分閱讀

第4≠r一-”M-

A

◎語篇解讀本文是一篇應(yīng)用文。文章介紹了幾個被稱為海洋的湖泊。

1.A細節(jié)理解題。根據(jù)TheAralSea中的“avastareaofabout68,000...itsoriginalsize”可知,咸海占據(jù)不

到68,000平方公里的10%,也就是說它的面積不到6,800平方公里;又根據(jù)TheCaspianSea中的“sizeof

about386,400squarekm”、TheSaltonSea中的“anareaofabout890squarekm”和TheSeaofGalilee中的

“anareaof166squarekm”可知,面積第二大的是咸海(TheAralSea)o故選Ao

2.B細節(jié)理解題。根據(jù)TheSaltonSea中的“LocatedinCalifornia,theUS...innature.”可知,索爾頓湖位于

美國加利福尼亞州。故選B。

3.C推理判斷題。根據(jù)第一段中的“However,thewatersknownastheseaarenotalltheendless

seas...magnificentlakes.”以及下文介紹的幾個被稱為海洋的湖泊可知,本文介紹的是有關(guān)海洋、湖泊等

地理方面的知識.故可推斷出喜歡地理的人會對該文章感興趣。故選C0

B

◎語篇解讀這是一篇說明文。文章講述了全球氣溫的上升導致珊瑚礁數(shù)量的減少以及珊瑚礁的減少

對人類的影響。

4.D細節(jié)理解題。根據(jù)第二段的“ariseinglobaltemperatureof1.5℃...declineby70%—90%”可知,全球

氣溫上升導致珊瑚礁數(shù)量減少。故選D。

5.A細節(jié)理解題。根據(jù)第二段的“Thisisalreadyaffectingrelations...whichgivethemtheirColOUr.”可知,

單細胞藻類賦予了珊瑚蟲顏色.也就是說珊瑚蟲的顏色是由單細胞藻類影響的。故選Ao

6.C推理判斷題。文章講述了全球氣溫的上升導致了珊瑚礁的減少以及珊瑚礁的減少對人類的影響，

因此本文很可能來自科學期刊。故選C

7.B推理判斷題。根據(jù)線索:全球氣溫上升一珊瑚礁數(shù)量下降一對魚類多樣性以及人類生活產(chǎn)生影響,

故可推斷接下來作者很可能討論解決方案或應(yīng)對策略及措施。故選Bo

C

◎語篇解讀這是一篇說明文。研究表明,北極河流的熱量上升正在導致北冰洋的海冰逐漸消融。

8.C細節(jié)理解題。根據(jù)第一段的“Anewstudy...graduallydisappear.”可知匕極河流的熱量上升導致北

冰洋的海冰逐漸消融。故選C。

9.D細節(jié)理解題。根據(jù)第二段第一句可知相比1980年,北極的主要河流給北冰洋帶來了更多的熱量.

故選D。

10.A詞義猜測題。根據(jù)第一段的描述可知,北極河流的熱量上升導致北冰洋的海冰逐漸消融:根據(jù)畫

線單詞后面的內(nèi)容可知,在西伯利亞北極地區(qū),有幾條大河流入北冰洋。因為北極河流的熱量使」版海

冰融化,而西伯利亞北極地區(qū)有好幾條大河流入北冰洋,所以在西伯利亞北極地區(qū),河流對北冰洋海冰的

影響是明顯的,prominent意為"明顯的”,故選A0

ILB主旨大意題。閱讀文章首句再結(jié)合全文內(nèi)容可知本文主要介紹了北極河流正在融化北極海冰的

情況?！氨睒O河流正在融化北極海冰”最適合作為文章標題。故選B。

D

◎語篇解讀這是一篇說明文。文章指出,海洋氧含量下降是一個與氣候變化相關(guān)的令人擔憂的趨勢。

12.A細節(jié)理解題。由第二段后三句可知,對于科學家來說,變暖的海洋正在失去氧氣并不奇怪,但下降

的幅度需要引起人們的注意。研究表明,在過去的50年里.一些熱帶地區(qū)的海洋氧含量下降了驚人的

40%,其他地區(qū)的降幅較小,全球平均降幅為2%。所以.科學家最擔心的是變暖的海洋中日益惡化的脫氧

現(xiàn)象。故選A。

13.C細節(jié)理解題。第三段說明了變暖的海洋缺氧的兩點原因,分別是:一、液體溫度越高,它能容納的

氣體就越少;二、當極地海冰融化時,它會在更冷、更咸的海水上形成一層水。這個過程會形成一種類

似蓋子的東西,它可以防止水流將表面的水與海洋深處的水混合。因為所有的氧氣都進入表面,所以較

少的混合就意味著海洋深處的氧含量更少。所以表面的極地冰水阻止氧氣下沉是海洋缺氧的原因之一。

故選C。

14.A推理判斷題。由第四段前兩句可知QSehIieS和他所在領(lǐng)域的其他人發(fā)現(xiàn),無論大小,海洋動物對

氧氣的微小變化都有反應(yīng),它們在氧含量較高的區(qū)域?qū)で蟊幼o或調(diào)整行為。這些調(diào)整可能使動物暴露在

新的食肉動物面前,或迫使它們進入食物匱乏的地區(qū)。所以海洋氧含量減少迫使動物離開自己的棲息地,

去氧氣含量較高的地區(qū)尋求庇護。故推斷出海洋脫氧改變了一些動物的自然領(lǐng)域。故選A。

15.D推理判斷題。通讀全文可知,文章說明了海洋氧含量下降是一個與氣候變化有關(guān)的令人擔憂的趨

勢,還說明了海洋氧含量下降的原因以及其對海洋生物的影響。所以文章主要是圍繞著海洋氧含量下降

而展開的。而這屬于科學的范疇,所以可推測出該文很可能來自科學期刊。

第一"P

◎語篇解讀這是一篇議論文。文章主要講述了我們越來越依賴海洋的資源,但是我們卻不斷地污染海

洋,作者希望人們減少海洋污染。

16.E根據(jù)空前句可知,我們每年從海洋中撈取數(shù)百萬千克的魚,來養(yǎng)活數(shù)十億人。由此推斷空處講述

海洋中的魚對人類的好處,故選E項。倒數(shù)第二段提到的fertilizer也是對此處的提示。

17.D根據(jù)空前兩句可知,人們從海洋中提取礦物,一種方式是通過蒸發(fā)海水獲得鹽,故D項承接上文關(guān)

于從海水中獲得鹽的描述,符合題意。故選D。

18.A根據(jù)空前兩句可知,來自海洋的其他禮物是珍珠、海綿和海藻。珍珠可以被制成珠寶,空后句說

海藻可以被制成多種食物（甚至糖果和冰激凌）以及藥品。故設(shè)空處應(yīng)講海綿的用途。結(jié)合選項,A項符

合題意。故選A。

19.F根據(jù)空前句可知.人不能喝海水,而空后句表明去掉海水中的鹽和其他雜質(zhì)就能得到淡水。空處

應(yīng)該承接上文,講喝海水的不良影響,F項符合題意。故選Fo

20.B本段主要講述了人們對海洋的污染。根據(jù)空前兩句可知.人們給海洋帶來了垃圾,污染了海洋,B

項承上啟下,符合題意。故選B。

第二部分語言運用

第4≠r一-”M-

◎語篇解讀這是一篇記敘文,講了作者帶領(lǐng)探險隊員去南極洲探險.度過了數(shù)月的嚴寒和黑暗。

2LA根據(jù)最后一段中的“…Isawthepictureofthepenguinthat34metolookattheadforthejob."可

知,作者看到企鵝的照片之后才看到工作的廣告,由此可知,作者承認是招聘廣告中的企鵝照片引起了他

的注意。故選A。

22.C根據(jù)最后一段中的”...metolookattheadforthejob.”可知,此處表示引起了“我”的注意。故選C0

23.Ckind種類;SUm金額;team隊,組;PieCe塊。根據(jù)第二段中的“Leading18StrangerS…”可知,18個人應(yīng)

為一隊。故選C。

24.B根據(jù)本段首句“Isawanadvertisementforajobasaleaderforanexpedition（探險）toAntaretiCa…''可

知,作者看到一則招聘南極洲探險隊領(lǐng)隊的廣告,而南極洲是地球上最偏遠的地方之一。古攵選Bo

25.B根據(jù)上文的“Itookpartin”以及下文的“andthengotajob”可知,作者參加了面試,然后得到了工作。

故選B。

26.D根據(jù)第三段的“Afterthejourney”可知作者得到了這份去南極洲的工作。由此推斷出“我知道如

果我不去做,我會后悔的。”故選D。

27.A上文提及“monthsofdarkness”可知,南極洲處于黑暗狀態(tài),是非常寒冷的,此處指無法擺脫寒冷。

故選A。

28.B根據(jù)第三段首句可知,探險歸來后,作者成了一名勵志演說家。故作者在探險過程中,學到了很多

有影響力的教訓。故選B。

29.D根據(jù)下文的“everydayIwouldthink31ofhowIhadoperatedasaIeader”可知膈離意味著必須

做大量的自我反省。古嬤E
