參考答案：

1.EC］事實判斷題。文章第3段第2句提到，這個問題的解答是

具有商業(yè)結(jié)果的。C中的business為原文中commercial同義改寫，

故選Co

2.［D］細節(jié)題。文章第4段首句為一個強調(diào)句，強調(diào)的是賓語。

題干也是一個強調(diào)句型，但強調(diào)的是主語。如果把原文的強調(diào)句型改

為一般的句型，就知道向Mauiry尋求幫助的是theAtlantic

TelegraphCompany.故答案為D。A是Maury的工作單位，可以排除;

原文只提到對于一些早期的穿越洲際的旅行家和依靠海洋維持生計

的人，海洋并不遙遠，故B、C與題意不符。

3.［D］事實判斷題。文章第4段提到，19世紀(jì)40年代，Maury

負(fù)責(zé)推動進行測深工作的海上航行，以此來探測北大西洋與太平洋的

深度.故選Do

4.[C]詞義推斷題。當(dāng)時的科學(xué)觀點是海洋較深的地方不存在生

命，而事實上在電纜表面發(fā)現(xiàn)了活的生物.由此可知這一事實對當(dāng)時

的科學(xué)觀點提出質(zhì)疑，故答案為C。

5.[A]主旨題。通讀全文可知，oceanography（海洋學(xué)）是全文的

中心詞，本文主要講述海洋學(xué)是如何起步的，故答案為A。B、C只

表述了原文中個別細節(jié)，并非主題;D跟全文無關(guān)。

答案：

1.[B]事實細節(jié)題。從文章第1段末句可找到答案。選項A顯

然與原文意思相反，選項C和D則無原文依據(jù)。

2.[C]推理判斷題。第2段第2句表明洛錫安勛爵捐贈了他的

房產(chǎn)后，這個計劃才啟動起來，因此選項C正確，也由此可以否定選

項A。根據(jù)第2段最后兩句可知這個計劃是為了保護具有歷史價值的

房子,而不僅僅是為了保護洛錫安勛爵的房子，因此選項D不對。

3.[B]事實細節(jié)題。最后一段從preserving開始的部分指出了

本題的答案。第3段倒數(shù)第2句所說的"nodevelopmentor

disturbancesofanykindarepermitted”可幫助排除選項A;選

項C內(nèi)容不完整;選項D中的限制詞primarily使用不妥,無原文依

據(jù)。

4.[C]詞義推斷題。由invade所在的句子Kforthemillions

oftouristswhoeachyearinvade.?！笨芍@是托管會保護自然

美景和歷史勝地的原因所在。從而可以推斷出invade強調(diào)來英國游

玩的游客之多，因此選項C為正確答案。

5.[A]主旨大意題。縱觀全文可發(fā)現(xiàn)theNationalTrust和

theTrust在文章開頭以及文中反復(fù)出現(xiàn),文章是一篇說明文，主要

目的是介紹theNationalTrust的機構(gòu)性質(zhì)及其功能，因此選項A

正確。文章未討論托管會的成員問題，因此選項B不正確。最后兩段

雖然提到英國的自然景色很美，但這并非文章的主題思想，因此選項

C不對。本題最具干擾性的是選項D,但是本文并不是一篇議論文，

其目的不是讓讀者認(rèn)同其中的觀點，文章更多的是用說明性的語言來

說明托管會的一些做法。

答案:

1.對于目前的網(wǎng)絡(luò)商務(wù)我們知道什么？

A）網(wǎng)絡(luò)商務(wù)不再時興。

B）企業(yè)對企業(yè)電子商務(wù)是潮流。

0網(wǎng)絡(luò)商務(wù)在消費市場正興旺。

D）許多公司對網(wǎng)絡(luò)商務(wù)依然缺少自信。

[D]第2段開頭的Nonetheless表明該句與首段提到的內(nèi)容有轉(zhuǎn)

折關(guān)系，而D與該句內(nèi)容相同，為本題答案。

2.在網(wǎng)絡(luò)商務(wù)中已建立關(guān)系的商業(yè)伙伴是優(yōu)先的，因為o

A）他們比其他人更可信

B）他們能詳細說明自己想要的產(chǎn)品

C）他們擁有進入公司專用內(nèi)部網(wǎng)的權(quán)利

D）他們能夠進行網(wǎng)上交易

[A]由第2段最后一句可知公司這樣做的原因是為“控制風(fēng)險”,

而再由上文中的reliability,trust等詞可看出風(fēng)險問題是源于''信

譽”問題，只有A與該段所說的核心意思相符，故選A。

3.PointcastNetwork最可能是。

A）研發(fā)最新推銷軟件的公司

B）促進公司網(wǎng)上營銷的工具

C）第一家使用網(wǎng)上推銷軟件的公司

D）幫助公司進行推銷的最流行軟件

[A]第3段第4句開頭的Mostnotably表明該句提及的Pointcast

Network是說明上一句觀點的例子，由此可見，PointcastNetwork

應(yīng)為一家開發(fā)軟件的公司，因此A為本題答案。

4.網(wǎng)絡(luò)純粹主義者最擔(dān)心o

A）只有被需求的信息顯示在屏幕上

B）網(wǎng)絡(luò)中滿是商業(yè)促銷

C）網(wǎng)絡(luò)和電視的區(qū)別會淡化

D）網(wǎng)上推銷技術(shù)將掌控屏幕

[D]第3段末句開頭的That'saprospect表明前面提到的內(nèi)容

就是使網(wǎng)絡(luò)凈化者覺得擔(dān)憂的問題，上文說網(wǎng)絡(luò)廣告不應(yīng)像電視那樣

不請自來，由此可見，網(wǎng)絡(luò)凈化者最擔(dān)心的是以后電腦屏幕會被不請

自來的廣告占據(jù)，因此D為本題答案。

5.關(guān)于亞馬遜我們能推斷出什么？

A）其成功源于網(wǎng)上推銷策略。

B）它沒有采用推銷策略，仍很繁榮。

C）它對計算能力的花費高度關(guān)注。

D）它是繁榮的網(wǎng)絡(luò)商務(wù)的一個很好的例子。

[B]末段首句中的hardlyinevitable（不是不可避免）表明有些

公司不使用“推銷”策略也可取得成功，第2句以Amazon.com為例

說明這個觀點，由此可見,B正確而A錯誤。

（五）

答案：

1.當(dāng)蛇遇到了潛在的敵人，它主要的做法會是。

A）避開任何監(jiān)視

B）找一個安全的庇護場所

C）給出一個警告威脅

D）開始快速攻擊

[A]首段第3句提到了蛇遇到可疑敵人時的行為模式：首先躲開

對方的監(jiān)視，第二步是尋找安全藏身處，第三是向?qū)Ψ桨l(fā)出警告，最

后實施攻擊，因此選項A為本題答案。選項B、C和D分別是對第二、

第三和最后一步的近義替換，因此都不是正確答案。

2.第1段里含有下劃線的短語“dispensewithallthe

preliminaries”的意思最可能是。

A）蛇結(jié)合了所有之前的三個步驟

B）蛇會放棄所有之前的三個步驟

C）蛇會依據(jù)之前的步驟一步一步進行

D）蛇會保留所有之前步驟的順序

[B]首段最后一句中dispensewith的前面提到過somestages

maybeomittedorcombined,而下文提至Uattackalmostatonce,

這稅明dispensewith應(yīng)表示有些蛇不做前幾個步驟，而立刻展開進

攻，因此它的意思應(yīng)等同于omit”免除，省略”,也即選項B中的give

upo其他選項語法上都說得通，但是與下文的attackalmostatonce

不一致，因此都不是正確答案。

3.蛇最有攻擊性的時候是o

A）遇到了可能是敵人的動物

B）在睡覺或蛻皮的時候給提住

C）在其沒有防備的情況下受到干擾

D）在交配季節(jié)求偶的時候

[D]第2段首句中第2個分句的mate一詞與選項D同義，因此選

項D為本題答案。其他選項都在文中提到過，也是蛇會對敵人實施還

擊的情況，但是這三個干擾項和正確選項之間的區(qū)別就在于，文中沒

有提到在這些情況下"Asnakeismostaggressive（蛇最具有攻擊

性）”，因此本題要緊扣第2段首句和其中的peak這個單詞。

4.很難預(yù)測當(dāng)蛇遇到人的時候會發(fā)生什么事情，因為o

A）從來就沒有人知道是怎么被蛇攻擊的

B）在形容與蛇遭遇的情形時，人們總是主觀性較強

C）在不同的情況下蛇的攻擊性程度都不一樣

D）沒有遭到挑釁的話，蛇是不會攻擊人的

[C]第2段最后兩句由So連接，顯示倒數(shù)第2句是原因，最后一

句是結(jié)果。選項C是對倒數(shù)第2句的概括，為本題答案。選項A和選

項D與題干之間沒什么關(guān)聯(lián)，易排除;選項B雖然與該段倒數(shù)第2句

的后一個分句意思相符，但它只是作為附加信息以說明蛇的個體行為

差異很大，故也可排除。

5.在最后一個段落中，作者使用了例子來支持他的觀點:

A）如果不受干擾的話，蛇是不會率先發(fā)起攻擊行為的。

B）一些蛇更具攻擊性，也更趨向隨時進行攻擊。

C）很難預(yù)測蛇是否會做出攻擊，會怎樣做出攻擊。

D）蛇主要的防衛(wèi)方式就是隱藏自己。

[C]第3段開頭就有forexample這個標(biāo)志性的詞組，表明這一

句是為了支持上文的例子。結(jié)合第2段末句可知，第3段是為了證明

其不可預(yù)測性的，故C正確。
