北师大必修二Unit4Informationandtechnology单元检测基础卷答案第一部分阅读（共两节,满分50分）第一节（共15小题；每小题2.5分,满分37.5分）A1.C【解析】主旨大意题。根据第一段的第一句“OurOnlineTrafficSchoolisdesignedtomakestudyinghereaseasyforyouaspossible.Nowastinggasdrivingtoclassrooms.Noextrathingstobuy.”可知，该段主要介绍的是网络驾校的优点。2.B【解析】细节理解题。根据第二段的第四、五句“Nosurprisingorextrachargesattheendofthecourse.Everythingisspelledoutahead...”可知，会事先告诉你费用，课程结束时并没有别的费用。3.A【解析】推理判断题。根据文章的最后一句“Simplycalluswithin30daysofsigningupfortheTrafficSchoolcourse.Signuptoday！”可知，这是一篇广告，目的是吸引学员。B4.D【解析】细节理解题。根据第四段中的“It'sfasterandeasiertocorrectifusingaputer.”可知，很多接受采访的学生认为电脑打字能够更快、更容易地改正错误。5.B【解析】词义猜测题。从后文可知，学生们过度依赖电脑打字，以至于某些汉字都不记得如何写了。故选B，表示“(对某情况)进行反思，作出评估”。6.A【解析】推理判断题。根据最后一段“...manyprimaryschoolsinBeijinghavemadewritingclassespulsory(必修的)andinuniversities,someprofessorsareaskingstudentstoturnintheirhomeworkandessayswrittenbyhand.”可知，北京的许多小学已经将书写作为必修课，大学里的一些教授要求学生提交手写的作业和论文。由此可推断A项正确。7.A【解析】标题归纳题。根据文章第一段及最后两段可知，很多人用电脑打字而忽视了手写，所以整篇文章是围绕用电脑打字还是手写来展开讨论的，故选A。C8.B【解析】推理判断题。根据第一段Americanhighschoolstudents...outagrade.“美国高中生是糟糕的写作者，一个教育改革组织认为它有一个答案：机器人。或者，更准确地说，机器人阅读者经过编程后可以扫描学生论文并给出分数的计算机。”由此可知，文本是为了介绍robot­readers。9.A【解析】词义猜测题。划线词所在句意为"或者更确切地说，robotreaders是浏览学生作文并____分数的被程序化的电脑"；由第四段最后一句"Ifstudentsfinishanessayat10pm，theygetaresultat10：01pm．"可推知，robotreaders可以给出分数，因此"spitout"在此意为"给出"，故正确答案为A。10.C【解析】推理判断题。根据第三段中Automatedessaygrading...tothetask.“论文自动评分在20世纪60年代首次提出，但当时的计算机无法胜任这项任务。”可知，从第三段我们知道，在20世纪60年代，计算机不能自动给文章打分。11.D【解析】细节理解题。根据最后一段中Theprogramscansfor...ahumanreader.“该程序扫描关键词并分析语义模式，Pearson声称它能像人类读者一样理解文本的意思。”可知，TheIntelligentEssayAssessor能够理解文章的意思。D12.A【解析】细节理解题。根据文章第二段可知：中央电视台的视频显示，这台打印机打印出了一个蜂窝状结构的平面部分，以及中国航天科技集团公司的标志，该公司是中国空间技术研究院的母公司。该实验由北京航天器制造厂研发和制造的3D打印机完成的。由此可知，视频上显示的是3D打印的过程以及产品。13.C【解析】细节理解题。根据文章第四段第二句可知：一旦基于太空的3D打印技术可以投入使用，它就可以广泛地应用于太空项目，因为宇航员可以利用它制造很多东西，而他们目前需要通过货运飞船的补给飞行来获得这些东西。根据第五段可知：3D打印机将在扩展太空任务中非常有用，比如在空间站中，因为它可以让宇航员在太空中快速方便地制造零部件。综上所述，一旦空间站有组件坏掉了，可以用3D打印机打印出来并替换上。故选C。14.B【解析】推理判断题。根据最后一段第二句可知：CoSats公司首席运营官白瑞雪表示，3D打印展开器比同类产品更轻、更坚固，在航天工业中具有巨大的潜力。由此判断出，最后一段的目的是讲述3D打印技术有巨大的潜力。15.B【解析】主旨大意题。文章主要介绍了中国在新发射的航天器中进行了首次太空3D打印实验。一旦基于太空的3D打印技术可以投入使用，将为未来的太空旅行节省大量的资源和成本。故B项（3D打印套件有助于简化太空旅行）作为本文标题，符合题意。第二节（共5小题：每小题2.5分,满分12.5分）16.E【解析】设空处前提出与在线(online)课程教授有着良好的沟通很重要，下文介绍了该做的和不该做的事情，因此答案为E项。17.G【解析】根据Do's和Don'ts中各段首句的特点可知，设空处为主题句并且是祈使句，设空处后一句中的关键词questions与G项中的questions对应，因此答案为G项。18.A【解析】由设空处前面的句子Participateindiscussionforums,blogsandotheropen­endedforumsfordialogue.中的关键信息可知，A项中的That指代dialogue，they指代discussionforums,blogsandotheropen­endedforums，因此答案为A项。19.C【解析】本段建议学生不要和教授聊个人话题，你在说完和教授沟通的内容之后，如果有必要，教授会进一步向你提问，因此答案为C项。20.F【解析】本段建议学生如果对教授的课程有意见，不要公开发表不满，所以空格处的内容应与本段话题一致，F项提到每个人都曾经上过不太好的课，与前后文内容相关联，因此答案为F项。第二部分语言运用（共两节，满分30分）第一节（共15小题：每小题1分，满分15分）21.C【解析】根据语境可知，虽然(Though)作者知道Wi­Fi帮助了自己，但是正是Wi­Fi的特殊作用让作者在做事情的时候会分心。22.D【解析】dividedattention意为“分心；分散注意力”。23.D【解析】根据语境可知，作者很多次都对自己承诺说要抑制(keepin)自己对Wi­Fi的情感。bringback“使回忆起，使想起”；agreewith“同意”；giveup“放弃”。24.A【解析】根据语境可知，此处形象生动地表现了作者不能抗拒Wi­Fi对自己的吸引。draw“吸引”符合语境。force“强迫，迫使”；observe“观察”。25.A【解析】Wi­Fi(本来)只是我们娱乐(entertainment)和获取信息的窗口。argument“争论”；development“发展”；struggle“斗争，奋斗”。26.B【解析】根据上文的“You'rejustawindowforour...information”以及“But”所表示的转折关系可知，此处表示人们并不满足于(satisfied)Wi­Fi仅仅是个“窗口(window)”。27.A【解析】结合下文中的“anillness”可知，作者疑惑的是自己和其他人对Wi­Fi如此依赖的现象是否是一种病(disease)。28.C【解析】如果对Wi­Fi的情感是一种依赖的话，Wi­Fi能保证与作者一生都亲密无间吗？promise意为“承诺”，符合语境。29.B【解析】Wi­Fi不能给自己放几天假以便它和作者都能放松(relax)一下吗？30.A【解析】Wi­Fi是一种能控制人们的思想并使人们随着它的音调起舞的毒药。danceto表示“随着……跳舞”。31.A【解析】根据下文中的“anyonecanbuy”可知，如今Wi­Fi的价格是如此低廉以至于任何人都能买到，并使其成为人们的伴侣。affordable“支付得起的，不算太贵的”；valuable“有价值的”；conventional“传统的”；attractive“有吸引力的”。32.B【解析】毫无生命的Wi­Fi是决不会在意其用户的健康的，但是用户们会一直担心Wi­Fi的“健康”，此处用always与上文的“never”形成对比，强调人们对Wi­Fi的在意程度。33.D【解析】根据下文中的“personmadeoffleshandblood(血肉之躯)”可知，作者想知道如果Wi­Fi成为拥有血肉之躯的真实的人，人们是否会一样喜欢它。selfish“自私的”；dishonest“不诚实的”；responsible“负责任的”
