江苏省2020-2021学年度第一学期新高考质量检测模拟试题

英语试题答案解析

听力1?5CABBC6?1OBACBC11?15AABBC16720AACAB

语篇解读本文为记叙文，作者通过介绍自己参加北极滑雪队选拔测试的

经历激励人们探索新世界，多展示自己的能力。

21,B［细节理解题。由第一段前丢句可知，作者在读到广告之后，下决心

去申请参加这项挑或，故选Bo

22,C［推理判断题。根据第三段中的“【foundoutthatthe

organizerswerenotlookingforamazingindividuals,butgreat

team

players,andthismomenthadshownthemwhowouldtakecareof

othersintheteam.”可知，组织者认为新人的选拔中团队精神是最重要

的，故选Co

23,D［写作意图题。根据作者对自己申请挑成和参加北极探险选拔测试

的描述，尤其最后一段中“IrealizedthatIcouldachievemorethanI

everimagined-moreimportantly,bysharingmystorywith

others,!couldinspirethemtotakeastepintothenewworldand

revealmoreoftheirabilities.“可知，作者旨在通过不他人分享诠故事,

激励他们迈出一步,进入新的世界，展示他们更多隐藏的能力，故选Do

语篇解读本文是一篇说明文。主要介绍了哪一种洗车方法对环境更有

益

处:在家还是去洗车公司。

24,B［推理判断题。根据第二段中的“Themainconcernswith

eitherchoicearetheamountoffreshwaterbeingused...”和“She

advisescarownerstoputasideasetamountofwaterforthe

entire

wash.”可推断，在外边洗车时，人们担心会浪费掉更多的水。

25,D［细节理解题。根据第二段最后一句"Butevenfollowingthis

advicecomeswithanenvironmentalrisk:Washingyourcarinthe

drivewayorstreetflushesthedirtywaterintostormdrains.（但即

使遵

循这一建议，也会带来环境风险:在车道戒街道上洗车会将脏水冲进雨

水

沟）”可知选D项。

26,B［标题归纳题。根据文章第一段最后丢句“这些额外的脏东西会使

我们做以下丢件事之一：在私人车道上洗车,还是去洗车处洗车。但是

哪种选择对环境更好呢？”可知，本文主要介绍了在与业洗车庖里洗车

和自己励手洗车,到底哪个对环境更有益处。故答案为Bo

语篇解读这是一篇说明文。分类对我们的日常生活至关重要，计算机一

旦学会了分类边界,它就可以确定某个数据是正的还是负的。这项技术

的困难之处在于,在学习过程中，它既需要正的数据，也需要负的数据，而

负的数据在很多情）牙下是不可用的。但是一项研究表明,在没有负数据

的情）牙下，只要我们对正数据有一个信心评分，我们就可以让计算机只

使用正数据来学习从而进行分类。

27,A［细节理解题。由第一段中的"Onceaclassificationboundaryis

learned,thecomputercandeterminewhetheracertaindatais

positiveornegative.”可知，一旦学习了分类边界，计算机就可以确定

某

项数据是正的还是负的。所以计算机通过学习分类界限区分正负数

据。故A选项正确。

28,D［推理判断题。由第二段中所举的例子可知，例如，当零售商试图预

测谁将购买商品时，他们可以很容易从购买他们商品的客户通里获得数

据（正数据），但基本上不可能从未从他们逼里购买过商品的客户逼里获

得数据（负数据），因为他们无法访问竞争对手的数据。所以提到第二段

中的例子是为了解释为什么很难获得负数据。故D选项正确。］

29,B［词义猜测题。由画线词所在句及其前一句可知，只要我们对我们

的正数据有一个由购买意向戒应用程序用户的活跃率等信息构成的信

心评分，我们就可以让计算机只从

有信心的正数据中学习分类。由此可知，画线词“newmethod”指的是

Buildingaconfidencescore“建立信心评分”。故B选项正确。

30,B［标题归纳题。通读全文尤其是第三段中的“butwehavemadeit

possibleforcomputerstolearnwithonlypositivedata,aslongas

wehaveaconfidencescoreforourpositivedata…”可知，在没有负

数

据的情7牙下，计算机也可以只使用正数据来学习从而进行分类。所以短

文的

最佳标题为“聪明的人工智能：在没有负数据的情7牙下，机器也能够学习

从

而进行分类”。故B选项正确。

语篇解读这是一篇说明文。如果你要出国读大学，你可能会考虑如何在

未来几年给自己找一个安全舒适的家。当然，宿舍总是一个好的开始。

但一

些大型州立大学由于宿
