【导语】本文是一篇应用文。文章是一则招聘信息，KHOU公司计划招聘一位有经验的兼

职编辑。文中说明了应聘条件，并对KHOU公司作了简要介绍。

1.细节理解题。根据Duties部分中的“Providevideomaterialtoourwebsiteasneeded."（根

据需要，提供视频资料到我们的网站）可知，兼职编辑需要为网站准备一些视频资料。故选

C项。

2.细节理解题。JobRequirements部分中的第一条要求“Collegedegreeswilhprevious

newsroomexperiencespreferred.”（大学学历，有新闻编辑部工作经验者优先）和最后一条要

求“Mustbeabletoworkaflexibleshiftandoccasionalovertime."（必须能够灵活轮班，偶尔加

班）可知，有相关工作经验、能够灵活轮班的人有资格应聘。故选D项。

3.细节理解题。AboutUS部分中的“Formorethan60years,KHOUhasbeenaleaderinlocal

journalism,informationandcommunityinvolvement.M（60多年来，KHOU一直是当地新闻、

信息和社区参与的领导者）可知，KHOU公司在60多年前就在当地的新闻行业处于领先

地位。故选C项。

4.C

5.A

6.B

7.D

【导语】本文是一篇记叙文。文章叙述了世界上最深海沟“ChallengerDeep”的探索历史。

4.细节理解题。根据第二段最后一句"The'ChallengerDeep'getsitsnamefromtheBritish

Navyvesselcalled'HMSChallenger'whichmadeafirstmeasurementofitsdepthin1875.”

「ChallengerDeep'这个名字来源于英国海军舰艇，HMSChallenger二这艘船在1875年第一

次测量了它的深度。）可知，“ChallengerDeep”的名字来源于英国的一所舰船。故选C项。

5.推理判断题。根据第二段“IfMountEverestisplacedinthedepthsoftheMarianaTrench,it

wouldbetotallysubmergedinwater,withabout2,000metersofwateraboveit!”（加果把珠穆朗

玛峰放在马里亚纳海沟的深处，它将完全淹没在水中，上面大约有2000米高的水！）由此可

推知，提及珠峰是为了显示马里亚纳海沟的深度。故选A项。

6.细节理解题。根据第三段最后一句"Unfortunately,Iheycoulddolittleexceptmeasuringthe

depthastheirdescentraiseddebriswhichreducedtheirvisibilitytozero.”（不幸的是,他们只能

测量深度，因为他们的下降产生了碎片，使能见度降至零。）可知，I960年，这两个人仅仅

测量了海沟的深度。故选B项。

7.细节理解题。根据最后一段第一句"Laterin1996,theJapaneseunmannedremotelyoperated

underwatervchiclc（ROV）,Kaikomadethedeepestunmanneddiveeverandbroughthome

samplesofbacterialivinginthesedepths."（1996年晚些时候，日本无人遥控水下航行器（ROV）

Kaik。进行了有史以来最深的无人潜水，并带回了生活在这些深度的细菌样本。）可知，日

本探索者从海沟带来了活细菌，即带回来活的有机体。故选D项。

8.A

9.B

10.C

11.D

【导语】本文是一篇说明文。一项新研究发现，攀登珠穆朗玛峰的人登顶的几率是2（）年前

的两倍，攀登过程中死亡率也降低了。

8.细节理解题。根据根据第二段第二句"Theyfoundthattheriskofdyingonthemountainwas

0.5percentforwomenand1.1percentformeninrecentyears.（他们发现,近年来，女性死于山

上的风险为0.5%,男性为1.1%）”可知，目前女性死于登山的风险为0.5%。故选A项。

9.细节理解题。根据第四段中第四句"Ifcrowdingslowsclimbers（asisexpected）,thisincreases

（heirexposuretotheelements,whichshouldincreaseriskofanaccidentorillness.（如果拥挤减

慢登山者的速度（正如预期的那样），这会增加他们接触恶劣天气的机会，因而加发生事故

或疾病的风险）”可知，deathzone减缓登山者的速度，增加他们暴露在自然环境中的机会，

也就增加了发生事故或生病的风险。故选B项。

10.词义猜测题。根据前文和最后—一段"ClimbershaveexpressedconcenthatNepalwasgiving

anyonewillingtopaythegovernment$11,000authorizationtoclimbEverest.（登山者表示对尼

泊尔正在向任何愿意向政府支付11000美元攀登珠穆朗玛峰的authorization而担忧）”可.知，

攀登珠穆朗玛峰很危险，但无论是谁愿意支付11,000美元来攀登珠峰，尼泊尔政府都会发

放许可，这一点使得攀登者们担忧。故推测此处画线词authorization的意思是“授权，许可”

的意思。故选C项。

11.主旨大意题。根据第一段“PeopleclimbingQomolangmaaretwotimesaslikelytoreachthe

topandlesslikelytodieontheclimbthan20yearsago,anewstudyfinds.Everestisthetallest

mountainabovesealevelontheearth.Itreaches8,848.86metersintothesky.Between2006and

朗玛峰的人到达山顶的可能性是20年前的两倍，在攀登中死亡的可能性也更小。珠穆朗玛

峰是地球上海拔最高的山峰。它达到8848.86米的天空。在2006年至2020年期间，大约三

分之二的登山者成功登顶。在那之前的15年里，只有大约三分之一的人一路走上了顶峰）”

可知，文章主要介绍了有关攀登珠峰的新研究发现：与
