【文章大意】本文主要讲述了科学家们已经建立了一个基于食物网的

数学模型预警系统，该系统揭示食物链中的生态平衡和破坏的原理和

提醒人们应该保护生态系统。

1.Whathavescientistsdiscoveredwiththehelpofmathematicalmodels

offoodwebs?

A.Thelivinghabitsofspeciesinfoodwebs.

B.Therulesgoverningfoodwebsoftheecosystems.

C.Theapproachestostudyingthespeciesintheecosystems.

D.Thedifferencesbetweenweakandstronglinksinfoodwebs.

选B。细节理解题。根据文章第二段Withsuchmodels,scientistshave

foundoutsomekeyprinciplesoperatinginfoodwebs.可次口，通过这些模

型，科学家们发现了一些在食物网中起作用的关键原理。由此可见,

科学家借助于食物网的数学模型发现了控制生态系统食物网的规则。

2.Astronglinkisfoundbetweentwospecieswhenapredator.

A.hasawidefoodchoice

B.caneasilyfindnewprey

C.stickstoonepreyspecies

D.canquicklymovetoanotherplace

选C。细节理解题。根据文章第二段Ifapredatorcaneat...preyto

recover.可知如果一个捕食者可以吃几个物种，它就可以在其中一个

物种灭绝后幸存下来。如果一个捕食者可以转移到另一个物种，当一

个捕食物种变得稀少时，更容易找到这个物种，那么这个转换就允

许原来的捕食者恢复。由此可见，当食肉动物粘在一个捕食物种上时,

发现两个物种之间有一个很强的联系。

3.Whatwillhappenifthepopulationsoftoppredatorsinafoodweb

greatlydecline?

A.Thepreyspeciestheydirectlyattackwilldieout.

B.Thespeciestheyindirectlyattackwillturnintotoppredators.

C.Thelivingenvironmentofotherspecieswillremainunchanged.

D.Thepopulationsofotherspecieswillexperienceunexpectedchanges.

选Do推理判断题。根据文章第三段第一句可知数学模型还表明，食

物网可能是不稳定的，顶部食肉动物的微小变化可能导致整个生态系

统的巨大影响。由此可见，如果食物网中顶级食肉动物的数量大幅度

下降，其他物种的种群将经历意想不到的变化。

4.WhatconclusioncanbedrawnfromtheexamplesinParagraph4?

A.Uncontrolledhumanactivitiesgreatlyupsetecosystems.

B.Rapideconomicdevelopmentthreatensanimalhabitats.

C.Speciesofcommercialvaluedominateotherspecies.

D.Industrialactivitieshelpkeepfoodwebsstable.

选A。推理判断题。根据文章第四段可知无计划的人类活动证明了顶级

掠食者自上而下控制的想法是正确的。在海洋中，我们在工业规模上

捕捞顶级掠食者，如鳍鱼，而在陆地上，我们杀死大型掠食者，如

狼。这些行动大大影响了生态平衡。由此可见，不受控制的人类活动

极大地破坏了生态系统。

它是研究野生动物的重要科学工具，并介绍了它的使用所带来的问题。

5.Whatdoestheunderlinedword“document“inParagraph2mean?

A.Remind.B.Enrich.

C.Appreciate.D.Record.

选D。词义猜测题。画线词所在句句意：科学家们已经能够用领先的技

术野生动物的"私人"时刻。根据上文“Camerasplacedin

hard-to-reachplaceshaveshoteverythingfromsmalldesertcatstolarger

snow-lovingcatsinthenorthernRockyMountains.”由此可推断出，科学

家们是利用这种新型摄像机记录了野生动物的生活，"Record"意为"记

录”，故选D。

D.Theymightbestolenbypeople.

选Co细节理解题。根据第四段关键句"ButWMIdirectorMatthew

Kauffmansaysasthosedevicesarelimited,soistheamountof

A.Itisdifficulttofixthecameras.

B.Ithelpshuntersfindanimalseasily.

选Bo细节理解题。根据倒数第二段关键句"Also,thedeviceshave

becomepopulartoolstohelphunterslookforanimals.Somepeopleargue

thatitisunfairtousethecamerasthatway.”由此可知，有些人反对使用

野外摄像机是因为它帮助猎人很容易地找到动物。故选Bo

8.Whatistheauthor'sattitudetowardswildcameras?

A.Doubtful.B.Positive.

C.Uncertain.D.Uncaring.

选B。观点态度题。根据最后一段内容“Evenwithsuchproblems,wild

camerasareclearlyanimportantscientifictoolinresearchingwild

animals.”（即使野外摄像机存在着一些问题，但它显然是研究野生动物

的重要科学工具。）由此可推断出，作者对野外摄像机的态度是支持的。

故选Bo

【文章大意】本文是说明文。主要讲述了作者为了欧洲旅游而学习语

言的情况。

1.A.AmericaB.AsiaC.AfricaD.Europe
