主题一关注科技创新情景1创新性研究探索Ⅰ.阅读理解A语篇类型：说明文主题语境：人与社会——研究发现——大熊猫肠道菌的作用【语篇解读】研究发现，在春末夏初大熊猫吃竹笋时，体内的肠道菌会使它们储存更多脂肪、增加更多体重。本文介绍了肠道菌如何影响大熊猫的消化并通过老鼠实验证实了肠道菌增重储脂的作用。1．答案与解析：A理解具体信息。根据第二段中的“Theirgut(肠道)bacteria...andstoremorefat”可知，春末和夏初时竹笋最有营养，此时大熊猫吃竹笋，肠道菌会发生变化，会使大熊猫增加更多的重量，储存更多的脂肪。故选A。2．答案与解析：D理解词汇。根据第二段可知，春末夏初时大熊猫体内肠道细菌发生变化，这种变化使大熊猫增加更多重量，储存更多脂肪，由此可推知，此处是说很明显大熊猫在一年中的这段时间会变得更胖。故选D。3．答案与解析：C推断。根据第五段中的“Researchersfoundthe...sameamountoffood”可知，研究人员发现，尽管吃了相同数量的食物，但被移植了竹笋季节收集的熊猫粪便的老鼠体重增加得多得多。由此可推知，大熊猫粪便对老鼠的体重有重要影响。故选C。4．答案与解析：B理解文章主旨要义。本文先讲述了一个研究发现，在春末夏初大熊猫吃竹笋时，体内的肠道菌发生变化，这会使它们增加更多体重和储存更多脂肪。之后通过老鼠实验证实了肠道菌增重储脂的作用。故可用“大熊猫肠道菌的作用”来作本文的标题。故选B。B语篇类型：说明文主题语境：人与社会——科学研究——手写更有利于记忆【语篇解读】一项新的研究表明，手写更有利于记忆。文章介绍了该研究的经过、为什么手写比打字更能帮助人们记忆新信息以及该研究的作者对使用键盘的看法等。5．答案与解析：A理解具体信息。根据第三段中的“Whileperformingthesetasks...recordedtheparticipants'brainwaves”可知，参与者被要求在研究中戴帽子是为了记录他们的脑电波。故选A。6．答案与解析：C理解具体信息。根据倒数第二段的内容可知，这项新研究的负责人AudreyvanderMeer表示，这表明当我们手写时，我们记忆得更好。这是因为写作涉及复杂的活动，会激活大脑的更多区域。大脑活动的增加给了大脑更多的“钩”来留住你的记忆。故可推知，AudreyvanderMeer试图解释的是为什么手写比打字更能帮助人们记忆新消息。故选C。7．答案与解析：B理解具体信息。根据最后一段的内容可知，事实上它的作者们指出，电脑和其他有键盘的设备在现代社会已经成为必需品。键盘尤其有利于那些有某些特殊需要的人(比如使用手有困难的人)，而且在速度方面，打字比书写要好，即他们认为打字仍然是必要的和有益的。故选B。8．答案与解析：D理解文章主旨要义。根据文章的内容尤其是第一段的内容可知，文章主要说明了一项新的研究发现，即手写更有利于记忆。由此可知，D选项“手写比打字更利于记忆”最适合作本文标题。Ⅱ.七选五语篇类型：说明文主题语境：人与社会——科学与技术——5G技术在旅游业中的应用【语篇解读】5G技术的发展给旅游业带来了运作方式上的改变，旅游业的重点也已经从技术本身转移到了改善业务成果和提高由技术驱动的旅客体验上。1．答案与解析：A根据上文可知，5G技术促进了旅游运营合作，根据下文可知，从行业的运作方式和旅客的角度都可以看出这一点。据此可以推知，空处应该是讲5G给旅游业带来的改变，A项与此匹配。2．答案与解析：F根据下文可知，5G技术有望为企业提供一个无线网络，改变人和机器使用数据的方式；与前几代网络不同，5G现在不仅被视为一个消费平台，而且被视为一个主要的通信平台，它还可以提供云连接和边缘处理，这可以提供实时业务洞悉和自动响应，并最终整合数十亿的物联网设备和数据。据此可知，本段主要介绍5G在通信方面带来的改变，故选F项。3．答案与解析：B根据上文可知，随着旅游公司用新的数字系统改变了它们的运营方式，它们的重点已经从技术本身转移到了改善业务成果和提高由技术驱动的旅客体验上；B项中的thatchange与上文相呼应，符合语境。4．答案与解析：E根据下文可知，客人可以参与参观房间和酒店设施，或者在计划行程时预览当地景点；据此可知，空处应该是讲客人可以用网络技术提前体验旅游设施。E项承接下文，且E项中的guests与下文的guests相呼应。5．答案与解析：G根据上文可知，为了准备推出这项新技术，旅游公司应该确保它们彻底了解客人对一流旅游体验的期望；据此可以推知，下文应陈述旅游公司在了解客人对旅游体验的期望后所采取的措施。G项陈述的是旅游公司采取的措施，符合语境。Ⅲ.语法填空语篇类型：记叙文主题语境：人与自然——太空探索——在太空过春节【语篇解读】本文讲述了神舟十三号宇宙飞船的宇航员在太空过春节的情况，包括展示对联、用红灯笼和中国结及剪纸装饰核心舱等。1．答案与解析：tospend考查动词不定式。名词被序数词修饰后接动词不定式作后置定语。根据thefirstChinese可知，该空用动词不定式。2．答案与解析：their考查物主代词。SpringFestivalgreetings和空处之间为所属关系，故用形容词性物主代词。3．答案与解析：displaying考查现在分词。主语CommanderZhai和动词display之间为逻辑上的主谓关系，故用现在分词形式；该处也可以看作状语从句的省略，省略了主语和be动词。4．答案与解析：health考查名词。形容词修饰名词，根据形容词good可知，空处用名词形式。5．答案与解析：in考查固定搭配。dressedin...为固定搭配，意为“穿着……”。6．答案与解析：a考查冠词。根据语境可知，此处泛指“一张贴纸”，且sticker的发音以辅音音素开头，故用不定冠词a。7．答案与解析：lanterns考查名词的单复数。lantern为可数名词，其前无限定词，故用复数形式。8．答案与解析：longest考查形容词最高级。根据语境并结合空前的定冠词the和空后的ever可知，该处指“中国载人航天计划中持续时间最长的一次”，故用所给词的最高级。9．答案与解析：havebeencompleted考查动词的时态、语态和主谓一致。根据时间状语“overthepastfivemonths”可知，该处用现在完成时，且主语Multipletasks为复数形式，与complete为被动关系。故填havebeencompleted。10．答案与解析：that考查同位语从句。分析该句结构可知，空处引导同位语从句，解释说明belief的具体内容，且从句句意完整，故用that引导。情景2科技与生活Ⅰ.阅读理解A语篇类型：说明文主题语境：人与社会——人际交往——别让电子设备影响家人交流【语篇解读】英国的一项研究发现只有不到1/4的家庭会每天放下电子设备一起吃饭。本文主要讲述了研究结果和一些人的观点。1．答案与解析：B理解具体信息。根据第二段中的“sixinten...twoquarrelsaday”可知，父母让孩子关掉电子设备是导致经常吵架的原因，故B项正确。2．答案与解析：C理解具体信息。根据第四段中的“itisvital...todeveloprelationships”可以看出，Dr.Colton认为远离屏幕、多和家人朋友面对面交流对建立良好关系是很重要的，故C项正确。3．答案与解析：A理解写作手法。根据第二段中的“foundsixintenadmit”和第三段中的“Almostallparents...with98percent”可以看出，作者通过罗列数据来展示研究结果，故A项正确。4．答案与解析：B理解文章类型。根据第一段中的“accordingtoaresearch”和第二段中的“Astudyof1，600parents...found...”可以看出，本文是一篇研究报告，这样的文章一般出自于科学报告，故B项正确。B语篇类型：说明文主题语境：人与社会——科学与技术——写字比使用键盘更有利于大脑【语篇解读】研究发现，随着数字设备在社会的广泛使用，用键盘代替手写成为一种新潮。但是，人类的大脑应当以尽可能多的方式与世界互动，这样更有利于思维的训练；手写比使用键盘更有利于大脑发展。5．答案与解析：B考查理解文章主旨要义的能力。通读全文尤其第二段中的“Shebelievesthatyoungchildren...manageakeyboard”及第三段第一句“Usingapeninvolvesmoreofthebrainthanusingakeyboard，hernewfindingsshow”可知，本文主要说明了手写比使用键盘涉及更多的大脑活动，更有利于思维训练，故B项正确。6．答案与解析：C考查推断的能力。根据第二段尾句中的“Shebelievesthatyoungchildrenshouldlearntowritebyhandsuccessfully”可知
