【解析】老鼠除了可以作为研究人类疾病的动物模型之外,它还有其他的一些研究价值:可
以为了解古代城市的大小提供线索,可以揭示我们的历史。
1.C理解具体信息根据第二段的"Thosenestsarefullofinformationaboutearlysettlers"可
知,这些老鼠窝充满了早期定居者的信息。由此可知,历史学家可能会从老鼠窝中了解到早期
定居者的生活条件。故选C项。
2.B理解具体信息根据第三段的"Inrats,DNA...thebrownratcanhelptellalargestoryabout
howpeoplespreadaroundtheglobe,Puckettfinds"可知,Puckett说,在老鼠身上,DNA”确实讲述
了一个关于人的故事”。Puckett发现,另一个物种一褐家鼠可以帮助讲述人类是如何在全球
范围内扩散的大故事。由此可知,褐家鼠可以帮助讲述一个大故事,因为它的DNA反映了它
的扩散经历。故选B项。
3.D推断明题意:本题问"DavidOrton的话是什么意思?"一寻线索:根据第四段中David
Orton说的话可知,大多数时候,古城往往位于现代城市的下面。你不能直接把整个东西都挖
出来。但是你可以跟着老鼠一定答案:由此可推知,DavidOrton的话的意思是老鼠可以为了解
古代城市的大小提供线索。故选D项。
4.C理解主旨要义(标题判断)通读全文可知,本文介绍了老鼠除了可以作为研究人类疾病
的动物模型之外,它还有其他的一些研究价值:可以为了解古代城市的大小提供线索,可以揭
示我们的历史。故选C项。

译文:它们展示了早期定居者使用的具体材料,这有助于历史学家了解他们可以为自己制造和
生产什么,以及他们必须从大洋彼岸进口什么。
【解析】本文主要介绍了一家中国初创公司Watrix开发出了步态识别技术。
1.C理解具体信息根据第二段中的"thetechnology...analysesthousandsofmetrics(指
标)...Alltheseindividualfeaturesgointoadatabasethatthesoftwarethengoesthroughwhen
attemptingtoidentifypeople"可知,这项技术分析了数千个关于一个人走路的指标,从他们的体
型、手臂运动的角度到他们的姿势,以及他们是脚趾向内还是脚趾向外的步态。所有这些个
人特征都会进入一个数据库,在试图识别人时,软件会通过数据库进行识别。也就是说,Watrix
通过建立一个包含众多个人指标的数据库来保证"步态识别”的准确性,故选C。
2.A理解具体信息根据第三段的"Gaitrecognition,ontheotherhand,ismuchmorereliable.
Itworksfromvirtuallyanyangle,andbecauseitanalysessomanymetrics,itcanidentifysubjects
eveniftheyattempttocovertheirlegs"可知,步态识别从几乎任何角度进行工作,因为它分析了
如此多的指标,即使实验对象试图遮住他们的腿,它也能识别出实验对象。由此可知,与人脸识
别相比,步态识别技术的优点是无识别角度限制,故选A。
3.D推断根据第五段中的"Thetechnologyhasalsobeentestedbypublicsecurityofficialsfor
thousandsofhoursandu
