石家庄二中2019-2020学年第二学期高一年级4月月考自主测试高一英语答案第一部分阅读理解（共两节，满分40分） 第一节（共15小题;每小题2分，满分30分）A【语篇解读】本文是一篇应用文，主要介绍了三款在日常生活中很实用的手机软件。1．D解析：细节理解题。根据第二段第一、二句“Habiticaturnsthegoalofforminggoodhabitsintoagame,withitsowncharactersandscoring.It’salotoffun,andtheappalsoletsyoubuildhabitswithfriendsandfamily.”可知，Habitica是一款培养用户好习惯的软件，该软件有自己的角色和得分，很有趣，还可以让你的朋友和家人受益。故D项正确。2．C解析：细节理解题。根据第三段尾句中的“theabilitytoseeyourprogressovertime,chartsshowinghowyourhealthisimproving,day­by­dayencouragement,andsomeadviceontechniquesforgivingupsmoking”可知，在这款软件中，你可以看到你的进步，通过图表你可以看到健康改善的过程，此外，用户每天还可得到鼓励和一些关于戒烟技巧的建议。故C项正确。3．B解析：推理判断题。本文主要介绍了三款在日常生活中很实用的手机软件，包括好习惯养成软件、戒烟软件和健康与健身软件。并结合第一段中的“amorebeneficialwayofliving”可推知，B项正确。B【语篇解读】本文讲述了ChristineLaw把婚礼上用过的花送给老人们，为他们的生活增加美的享受，她的做法得到了很多人的支持。4.A解析：细节理解题。根据第一段中的“‘Wheredoalltheflowersgoaftertheparty？’Moreoftenthannot,theywerethrownaway.Lawwasconfidentshecouldfindabetteruseforthem.”可知，婚礼上使用过的花束的浪费使ChristineLaw成立了Floranthropie这个机构。故选A。5．D解析：推理判断题。根据第二段中的“ThefirstwomanIapproachedthoughtitwasamistake,andthattheflowerscouldn’tpossiblybeforher”可推知，当ChristineLaw给第一位女士送花时，她感到难以置信。故选D。6．C解析：推理判断题。根据第三段中的“Floranthropiehelpsusdothat.It’samazingwhatabigdifferenceasmallbouquetcanmake.”可推知，LaëtitiaThélème认为Floranthropie做的事产生了很大影响，故C项符合文意。7．D解析：标题归纳题。本文主要讲述了ChristineLaw为了不浪费婚礼上用过的花，把花送给老人们，给他们的生活带来了美。故D项适合作文章标题。C【语篇解读】本文是一篇说明文。研究发现眨眼并不会错过细节并解释了其原因。8．A解析：推理判断题。根据第二段第一句“AccordingtoanewstudypublishedinthejournalCurrentBiologyinSeptember,ourbrainhastheabilitytoskipthetemporarydarknesswhenweblink.”可知，九月份发表在《当代生物学》杂志上的一项新研究表明，我们的大脑有能力跳过我们眨眼时形成的暂时黑暗。据此可推知，由于我们的大脑能处理丢失的图像，所以眨眼不会让我们错过任何东西，故A项正确。9．B解析：代词指代题。根据第二段第二句“Itcankeepvisualinformationforashortperiodoftimeandthenputittogethertoformanimagewithoutinterruption.”可知，大脑可以在短时间内保存视觉信息，然后将其组合在一起形成不中断的图像，故可推知，it指代上文中的“visualinformation”，故B项正确。10．D解析：细节理解题。根据第四段中的“whenthedirectionsoftwopatternsdidn’tmatch,theareainourbrainwhichisresponsibleforvisualmemorywasactivated.Thissameareashowedlessactivitywhentwopatternswereinthesamedirection”可知，当两种模式的方向不一致时，掌握视觉记忆的大脑区域被激活；当两种模式在同一方向时，这个区域显示出较少的活动。据此可知，不同的方向能激活视觉记忆，故D项正确。11．C解析：标题归纳题。通读全文可知，本文主要介绍了一项科学研究。研究表明，眨眼不会错过细节并解释了其原因，即大脑有能力在短时间内保存视觉信息，然后将其组合在一起形成不中断的图像信息。故C项最适合作本文的标题。D【语篇解读】本文介绍了科学家通过实验对乌鸦智商的研究。12．B解析：细节理解题。根据第三段最后一句“Thecrowsfoundoutthattheycoulddroptheerasersintothetubesinordertoraisethewaterlevelandgettheirsnack.”可知，乌鸦能够把橡皮擦扔到管子里，使水位升高，然后吃到零食。故选B项。13．D解析：推理判断题。从第四段可知，实验中的乌鸦在面对粗细不同的管子时，虽然只需往细管里投两次物体就可以获得零食，而需往粗管里投大约七次物体才能够获得零食，但是乌鸦往往先去粗管那边，而没有选择更容易获得零食的细管。由此可推知，画线部分是说它们通常没有选择更容易的方式来获得零食。14．C解析：主旨大意题。根据第二段最后一句“Theresultssuggestthatthebirdsare,atleastinsomeaspects,assmartasfirst­graders.”以及下文中的实验可知，整篇文章都是围绕乌鸦的智商问题来展开的。15．A解析：推理判断题。根据第二段最后一句“Theresultssuggestthatthebirdsare,atleastinsomeaspects,assmartasfirst­graders.”可知，乌鸦在一些方面几乎跟一年级的学生一样聪明。第二节七选五(共5小题；每小题2分，满分10分)【语篇解读】本文是一篇说明文，讲述了让自己早起的终极绝招。16.E解析：根据本段小标题“Calculateyourperfectbedtime.”及下文“Foraweek...calculatebackwardsfromthetimeyouwanttogetupandplantogotobedatthatnewhour.”可知，本段建议计算出你的理想上床时间。17.C解析：根据上文“Andcontrarytopopularadvice，youdon'thavetoturnoffthelightrightbeforebed.”及下文“butreadingathrillermaynotbethebestidea.”可知，与普遍流行的建议相反，你睡觉前不必关灯。阅读是放松的好方法，但是读一部恐怖小说可不是最好的主意。18.D解析：根据本段小标题“Createamorningto­dolist.”及下文“Thiswayyou'llfeellikeyou'reonataskwhenyouwakeup，you'llgetclosertoyourmorninggoalandyou'llhaveaclearscheduletofollow.”可知，本段建议罗列好早起事宜，写出第二天要做的三项工作。19.B解析：根据下文“Peoplewhoexerciseareeasytosleepbetterthanthosewhodon't.”可知，锻炼的人往往比那些不锻炼的人睡眠质量高，故B项符合题意。20.F解析：根据上文“Indeed，studieshaveshownastrongconnectiontoabetterqualityofsleepforpeoplewhoworkoutatleast10minutesaday.”可知，事实上，研究表明，每天至少锻炼10分钟与睡眠质量高有大大的关联性。原因之一：运动可以降低你的压力水平，这反过来又有助于对抗失眠。第二部分语言知识运用(共两节，满分50分)第一节(共20小题；每小题1.5分，满分30分)【语篇解读】Steve曾经每次考试都不及格，但是MissWilma看到成绩的时候，却说他是班里最聪明的学生，而且告诉他老师非常关心他。Steve感受到老师对自己的良苦用心，从此刻苦学习，改变了自己的命运。老师对他的影响促使他用同样的方法去影响并且帮助更多的人。21．B解析：根据
