宁夏银川二中2020-2021学年高二上学期月考(一)语文试题 Word版含解析
银川二中2020-2021学年第一学期高二年级月考一语文试卷注意事项：1．本试卷共22小题，满分150分。
考试时间为150分钟。
2．答案写在答题卡上的指定位置。
考试结束后，交回答题卡。
一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成下面小题。
文字是文明发展的载体，记录了一个国家和民族的历史发展进程与经验教训。
古人说，欲灭其国者，必先灭其史。
同样，如果一个国家和民族的文字消亡了，其文明发展的根基也就动摇了。
汉字是中华优秀传统文化能够代代相传并不断繁荣发展的根基。
传承中华优秀传统文化、建设社会主义文化强国，应将汉字教育作为凝神聚力、铸魂固本的战略工程。
清末民初以来，在日本“脱亚入欧”的影响下，中国一些知识分子对中华文化的根基——汉字产生了怀疑。
“汉字落后”论者认为“汉字不灭，中国必亡”，声称汉字的出路在于“拉丁化”；“汉字难学”论者主张汉字“拼音化”与“简化”；“儿童识字有害”论者主张放弃汉字教育。
这些论调在近几十年仍有一定市场，比如20世纪80年代，有人就认为“计算机是汉字的掘墓人”。
当前，汉字教育在实践中遇到的问题主要来自两个方面。
一是面临外语教育的挑战。
现在，英语是学生的必修课，学习英语在一些人看来可以改变命运。
受这种价值观影响，在汉语与英语之间，一些人更重视学习英语，这直接冲击与削弱了汉字教育。
二是面临信息化的挑战。
随着信息化的迅猛发展，人们通过敲击键盘输入汉字的场合越来越多、越来越便捷。
在古人眼中曼妙婀娜、形神兼备的汉字，现在变成了电脑键盘、手机屏幕上字母组合的产物。
在日常工作生活中，书写汉字的机会在变少，提笔忘字的时候在增多。
从这些角度来说，汉字面临危机绝不是危言耸听。
汉字是一种象形文字，具有“形、音、义”三要素。
汉字不单单表达概念、内涵、外延等，还给人带来图形、联想、感觉等。
与拼音文字相比较，汉字具有鲜明特色和独特魅力。
学习与理解汉字，应遵循汉字自身的规律和特点。
拼音文字是由字母组成的文字，其教学是用拼音的方法。
我国汉字教学引进了这种方法，并将其作为汉字教学的主要方法。
这种用拼音文字的教学方法来进行汉字教育的理念与实践有哪些优点和缺点，值得我们深思。
近年来，随着国人文化自信的提升，适应汉字在海外传播的需要，不少学者开始重新审视汉字教学的方法，合理借鉴我国传统汉字教学的经验。
有的教学实验根据“形、音、义”三要素和儿童擅长“形象记忆”的特点，探索“从字形讲字义，从生活讲汉字”和“因形分类、因类施教”等汉字教学的新理念与新途径。
通过这些方法，一些汉字教育工作者尝试把每个汉字的文化基因形象生动地传授给学生，让学生对汉字有兴趣、生爱恋、晓逻辑、会思考，甚至实现以字养德。
这类教学实验，对完善汉字教育有积极意义。
加强汉字教育，除了不断创新汉字教学的方式方法，更重要的是提升全社会对汉字教育的重视程度。
我们要把汉字教育提升到传承中华优秀传统文化、传承中华民族精神高度来认识。
只有这样，才能让古老的汉字在信息时代焕发新的生机，才能把中华文化的优秀基因植根于一代代中国人心中。
(摘编自王殿卿《汉字教育攸关文化传承发展》)1. 下列关于原文内容的理解和分析，正确的一项是( )A. 清末民初一些知识分子对汉字产生了怀疑，原因之一是当时国人的文化自信不足。
B. 现在一些人鄙视汉语而重视英语，直接冲击和削弱了汉字教育，不利于文化传承。
C. 汉字教学的方式方法的创新，有助于实现以字养德，从而激发学生对汉字的兴趣。
D. 汉字记录着国家和民族的历史发展进程与经验教训，是中华民族繁衍发展的基础。
2. 下列对原文论证的相关分析，不正确的一项是( )A. 文章引用20世纪80年代某些人的观点，是为了证明汉字不能适应信息化的挑战。
B. 文章从历史与现实两个角度分析了汉字面临的危机，指出了加强汉字教育的必要性。
C. 文章在论证汉字教学时，强调应遵循汉字自身的规律和特点，借鉴传统汉字教学经验。
D. 文章首尾呼应，论述了汉字教育的重要意义，并对如何加强汉字教育提出了建议。
3. 根据原文内容，下列说法不正确的一项是( )A. 如果我们不进行汉字教育而使用拉丁化文字，则我们文明发展的根基必然被动摇。
B. 汉字的形音义三要素，决定了汉字教育必须摒除拼音教学法，使用形象化教学法。
C. 创新汉字教学法，提升全社会对汉字重视程度，有助于让古老汉字在信息时代焕发新生机。
D. 日本“脱亚入欧”对中国一些知识分子影响很大，有的人甚至提出废除汉字的主张。
【答案】1. A 2. A 3. B【解析】【1题详解】本题考查学生对文本内容的筛选整合和理解分析能力。
题目要求选出“下列关于原文内容的理解和分析，正确的一项是”，B项，“在一些人鄙视汉语而重视英语”曲解文意，原文是“在汉语与英语之间，一些人更重视学习英语”，没有鄙视之意；C项，“有助于实现以字养德，从而激发学生对汉字的兴趣”逻辑错误，原文中是递进关系，先产生兴趣，后实现以字养德；D项，“汉字……是中华民族繁衍发展的基础”偷换概念，原文说“汉字是中华优秀传统文化能够代代相传并不断繁荣发展的根基”，并不是“中华民族繁衍发展的基础”。
故选A。
【2题详解】本题考查学生对论点、论据、论证以及论证结构等的分析把握能力。
题目要求选出“下列对原文论证的相关分析，不正确的一项是”，A项，“……是为了证明汉字不能适应信息化的挑战”分析错误，文章提到20世纪80年代某些人的观点，是为了证明质疑汉字的论调在近几十年仍有一定市场。
故选A。
【3题详解】本题考查筛选整合信息，把握文中观点态度能力。
题目要求选出“根据原文内容，下列说法不正确的一项是”，B项，错在“必须摒除拼音教学法”。
从原文看，作者虽然强调应遵循汉字自身的规律和特点，但只是讲在对拼音教学法进行反思，并没有说这种教学法就不适用于汉字教育必须摒除。
故选B。
【点睛】做选择题，基本方法是排除法。
但还要用好“比对法”。
就是把选项内容与原文有关内容认真、仔细地比较、对照，不符合原文意思的，就是错误项，反之则为正确项。
那么，要比对哪些内容呢？比对词语，命题者在设置选项时对原句作了改装、重组，即主要采取了“删”(删除原文的状语、定语、补语，改变原意)、“漏”(只强调问题的一个方面，有意漏掉重要信息，断章取义)、“改”(改换词语，曲解文意)、“凑”(胡乱拼凑、东拉西扯、无中生有、随意组合信息)等方式设误。
要看看选项在对原句改造过程中，删去了哪些词，改了哪些词，添了哪些词，它们是否与原文意思一致。
一般而言，选项中的下面这些词语最值得我们优先比对：指代词(如“它”“其”等)，比对它是否有偷换概念之嫌；范围词(如“都”“所有”“人人”等)，看它是否有任意扩大或缩小外延现象；程度词、时间词(如“或许”“大概”“必定”“可能”“似乎”“已经”“将来”等)，看它是否混淆偶然与必然、已然与未然，说法绝对等。
比对关系，(句间、分句间的逻辑关系)，看这种关系是否符合原文意思，是否合理。
比对句间关系，则要求考生不只是单纯地筛选信息，更应在筛选的基础上关注信息间的联系。
因此，比对分句间的逻辑关系是比对的重点内容。
比对关系分两步：第一步，逐项审查每一个选项有几个分句(包括句子)，分句与分句之间是什么关系(重点抓关联词)，一般的有因果、条件、假设、目的等关系，但以因果关系居多。
第二步，比对每一分句的意义在原文是否有依据，分句与分句之间的逻辑关系在原文中是否有依据。
尤其看因果关系，是否有强加、倒置不当。
比对依据和结论，看推断是否成立。
推断题选项的表述，有的是完整的推断形式，原因结果或条件结论同时出现；有的只是一个判断句。
对完整推断形式的表述，一看所述原因或条件文中是否有依据，二看所述结果(结论)文中是否有依据，三看原因或条件与结果或结论之间是否有合理的逻辑关系。
对只是一个判断句的表述，一看文中是否提供了现成的结论，二看结论(既然是推断想象，“这个结论”文中往往没有提供)是否符合客观事实与逻辑事理。
（二）实用类文本阅读（本题共3小题，12分）阅读下面的文字，完成各题。
材料一：端牢“中国饭碗”，在今年有着特殊意义。
上半年新冠肺炎疫情突如其来，对粮食生产、加工物流等造成一定影响，国际粮食市场变动等外部因素也引发对粮食安全的关注。
经多方努力，夏粮迎来了十七连丰，给国家粮食安全、老百姓端牢饭碗增添了信心和底气。
把饭碗端在自己手上，就要抓实眼前。
要严格落实最低收购价政策，在符合条件的地区及时启动托市收购，同时大力抓好市场化收购，严查各类违法违规行为，防止农民“卖粮难”。
7月中下旬是夏玉米苗期，各级农业农村部门要高度重视草地贪夜蛾等病虫害防治，压实防汛责任，落实防御措施，工作再加紧、措施再加力。
把饭碗端在自己手上，必须谋划长远。
落实粮食安全省长责任制，加快推动出台粮食安全保障法，扎实开展高标准农田建设，实施东北黑土地保护性耕作行动计划，加快发展现代种业，深化粮食收储制度改革。
碗中装好粮，就要促绿色显“特色”，让绿色生“金色”。
要深化农业供给侧结构性改革，深入推进优质粮食工程，继续实施大豆振兴计划，增加绿色优质粮油产品供给，促进农民增收、企业增效，使消费者得实惠。
碗里装好粮，就要充分发挥科技力量，推进农村科技创新。
疫情之下的农业生产中，植保无人机、线上农技“问诊”和农资购销发展迅速。
要以此为契机，让地理位置服务、新一代互联网技术等给粮食生产插上翅膀，加强农科人才培养，切实强化粮食安全科技支撑。
民为国基，谷为民命。
越是面对风险挑战，越要端稳中国碗，盛满中国粮。
(摘编自新华社记者于文静《端牢“中国饭碗”保障粮食安全》，2020年7月13日) 材料二：有些土地需要祛除“病灶”。
华北地区地下水超采对耕地利用造成影响。
近年来，华北地区通过节水、农业结构调整等措施压减地下水超采。
河北省曲周县地处华北平原，属于地下水超采区。
曲周县第四疃镇王庄村种粮大户王拥军今年种了200亩小麦，其中100亩是抗旱节水小麦品种。
“这100亩少浇了一遍水，就节水8000立方米，但产量却相当于普通高产小麦。
”王拥军说。
近年来，曲周县大力发展节水农业，全县10个乡镇设立11个节水小麦示范方，引进17个抗旱节水小麦品种。
今年该县推广节水小麦9.2万亩，压减地下水开采400万立方米。
河北省邯郸市邯山区境内滏阳河和支漳河的引水工程，可辐射灌溉面积5.1万亩。
邯山区水利局工程科科长于志信说，原来地下水灌溉的农田，土地有板结，现在使用“活水”灌溉，微量元素多了，土壤结构改良了。
河北省水利厅相关负责人表示，随着地下水超采治理不断深入，河北地下水位下降趋势有所减缓。
土壤污染也是耕地的一大“病灶”。
针对农药包装废弃物对耕地的污染问题，近年来，黑龙江省启动农药包装废弃物回收处理试点。
黑龙江省嫩江市伊拉哈镇的农民王全，闲暇之余就去田间捡农药瓶，然后送到固定回收点，每个农药瓶能换回0.1元。

宁夏银川市第二中学2021-2022学年高二下学期第一次月考语文试题
阅读下面的文字，完成下面小题。
区块链技术
材料一：
“区块链技术是一种基础设施，由密码学、分布式通和技术的信任来建立机制，改变了传统的依赖中心节点的信息验证模式。基于这种特性，人们可以构建在没有中介辅助下多个参与方之间的资产交易、价值传递的网络，通过建立执行智能合约，推动契约关系和规则的维护和履行，营造良好市场环境。专家介绍，区块链可以通俗地被理解为一个分布式的共享账本，这个账本由各个区块连成一个链条。在传统记账系统中，记账权掌握在中心服务器手中。而在区块链这个“账本”上，链条上的每一个点都能在上面记录信息，构成点对点的记账系统。因此，区块链技术被认为是一种去中心化的技术。更关键的是，由于以非对称密码算法加密，区块链上的数据难以被篡改，保证了信息的可信度、真实性。
C.历经流变的新写实主义诗歌成为当今诗坛的新主潮，但它强调自我独特的创作风格，难以产生里程碑式的诗篇。
D.唐代著名诗人白居易曾说：“文章合为时而著，歌诗合为事而作。”这与文中坚守与时代同行的创作理念是相通的。
【1~3题答案】

【点睛】做选择题，基本方法是排除法。但还要用好“比对法”。就是把选项内容与原文有关内容认真、仔细地比较、对照，不符合原文意思的，就是错误项，反之则为正确项。那么，要比对哪些内容呢？比对词语，命题者在设置选项时对原句作了改装、重组，即主要采取了“删”(删除原文的状语、定语、补语，改变原意)、“漏”(只强调问题的一个方面，有意漏掉重要信息，断章取义)、“改”(改换词语，曲解文意)、“凑”(胡乱拼凑、东拉西扯、无中生有、随意组合信息)等方式设误。要看看选项在对原句改造过程中，删去了哪些词，改了哪些词，添了哪些词，它们是否与原文意思一致。
2020-2021学年高中语文新教材人教版选修上册同步练习：综合测试 Word版含解析
综合测试(时间:150分钟满分:150分)一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成第1~5题。
材料一记者:祝晓宏:语言景观是由语言形成的、具有语言学意义的实物性景观。
关于语言景观的界定,引用最广的莫过于以色列社会语言学家Landry和Bourhis的定义:指的是特定地区和区域里公共或商业标牌上的语言。
他们用举例的形式罗列出了常见的语言景观形态,如街牌、路牌、广告牌、商业招牌、海报等。
随着时代的发展,语言景观有了更新的语言介质,也包括涂鸦、电子广告牌、移动广告牌、网络视频广告等。
一个国家和地区的语言生态、语言政策和语言实践的关系往往是很复杂的。
我们可以借由语言标牌中目标语言的各种信息来描写公共场所的语言使用情况,从而揭示这种关系。
同时,语言景观打破了语言的口语和书面二维对立关系,提醒人们注意语言的多维存在形式。
语言景观研究唤醒了我们对视觉化语言符号资源的重视,拓宽了语言研究的范围。
记者:祝晓宏:短短几年,语言景观研究迅速崛起,这些研究具有较强的问题意识和应用倾向,有助于弥合社会语言学领域内语言使用和宏观语言政策研究脱节的情况。
当然,目前对于拍摄到的语言标牌还没有达成标准化的标注意见,因为缺乏一致的编码框架,资源库搭建的基础工作也只能各自为政,这也限制了大规模比较研究的开展。
另外,当前的调查对象主要集中在一线城市,小城市极少,农村地区尚属空白。
记者:祝晓宏:语言景观研究还在升温,可以预见更多学科背景的学者将会关注这一领域。
为凸显语言景观的应用品味和交叉属性,研究视角还需要进一步拓展。
例如,需要思考语言景观与母语教育、外语学习的关系,语言景观与语言经济的关系等。
(选自《语言景观研究视角需进一步拓展——访暨南大学祝晓宏教授》,有删改) 材料二近年来,语言景观已经成为社会语言学研究的热点,彰显出蓬勃的生命力。
语言景观一般具有两种功能:信息功能和象征功能。
语言标牌可以为当地居民或来访者提供诸如位置、方向、店铺的经营业务等最基本的信息,并反映某种语言的使用状况及该地区的语言生态。

第Ⅰ卷阅读题一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成下列小题。
从民间文化的角度看，守住青山绿水，是中国传统自然观、宇宙观的体现。
失去了青山绿水，人们对众生万物的敬畏和想象，对自然山水的能动和悦纳，对生活空间的叙述和表达，就失去了依托。
人类对自然的认识，经历了一个漫长的发展历程。
对万物众生的敬畏和想象，是中国人认识自然的起点。
如在先秦古籍《山海经》(包含神话、地理、物产等内容)中，我们可以感受神州大地幅员之辽阔，见识山川物产之丰饶，更会为里面诡谲华丽的自然世界所震惊。
日本民俗学家伊藤清司曾将《山海经》中的空间划分为内部世界和外部世界，前者指人类的生活空间，与之相对的即外部世界，二者相对独立、互为依存。
在虔诚仰慕并企图利用大自然之余，人类对神秘而又神圣的未知世界充满了敬畏。
循着对善灵瑞兽的正面想象，人类赋予自身走向自然的合法性；对怪力乱神的负面想象，又恰如其分地给予人类种种约束，避免因过度索取而对自然造成严重破坏。
人们对自然的敬畏和想象，不仅在((博物志))《述异记》等历代文献中得以记载，而且在世代民众生活中实践传承。
我们在乡间田野常见的山神庙、龙王庙，正是内部世界与外部世界的象征边界。
敬畏在信仰中流淌，想象在仪式中演绎。
进入内部世界，民众对生活环境的选择更有能动性，对秀美山水的悦纳更具艺术性，同时也更能反映民众的生活关学。

Reading ComprehensionSection ALet's face it: while we go to the office to work, no one is expected to keep their head down the entire time they're there.

Passages(A)Massive changes in all of the world's deeply cherished sporting habits are underway.Whether it's one of London's parks full of people playing softball, and Russians taking up rugby,or the Superbowl rivaling the British Football Cup Final as a televised spectator event in Britain,the patterns of players and spectators are changingbeyond recognition. We are witnessing a globalization of our sporting culture.That annual bicycle race, the Tour de France, much loved by the French is a good case in point. Just a few years back it was a strictly continental affair with France, Belgium and Holland,Spain and Italy taking part. But in recent years it has been dominated by Colombian mountain climbers, and American and Irish riders. The people who really matter welcome the shift toward globalization. Peugeot, Michelin and Panasonic are multi-national corporations that want worldwide returns for the millions they invest in teams. So it does them literally a world of good to see this unofficial world championship become just that.This is undoubtedly an economy-based revolution we are witnessing here, one made possible by communications technology, but made to happen because of marketing considerations.Sell the game and you can sell Coca Cola or Budweiser as well.a American football has been sold to Europe is a good example ofhow all sports will develop. The aim of course is not really to spread the sport for its own sake, but to increase the number of people interested in the major money-making events. The economics of the Superbowl are already astronomical. With seats at US$125, gate receipts alone were a staggering $10, 000, 000. The most important statistic of the day, however, was the $100, 000, 000in TV advertising fees. Imagine how much that becomes when the eyes of the world are watching.So it came as a terrible shock, but not really as a surprise, to learn that some people are nov suggesting that soccer change from being a game of two 45-minute halves, to one of fou25-minute quarters. The idea isunashamedly to capture more advertising revenue, without giving any thought for the integrity of a sport which relies for its essence on the flowing nature of the action.Moreover, as sports expand into world markets, and as our choice of sports as consumers also grows, so we will demand to see them played at a higher and higher level. In boxing we have already seen numerous, dubious world title categories because people will not pay to see anything less than a "World Title" fight, and this means that the title fights have to be held in differe countries around the world!56.Globalization of sporting culture means that___________A.more people are taking up sportsB traditional sports are getting popularC.many local sports are becoming internationalD. foreigners are more interested in local sports57. Which of the following is NOT related to the massive changes in the world's deeply cherished sporting habits?A.Good economic returns.B.Revival of traditional games.C. Communications technology.D. Marketing strategies.58. The author's attitude towards the suggestion to change soccer into one of four 25-minut quarters is______.A. favorableB. neutralC. reservedD. critical59. This passage mainly discusses_.A.the commercialization of sporting cultureB.the worldwide popularization of sportsC.the speculation in sporting eventsD.the restoration of sportsmanship(B)We asked you to________in 50 words or fewer. Once again, you didn't disappoint us.Here are our favourites, Which one do you like the best? Write and let us know.[1] My uncle has a 1974 Ferrarl Dino 308-'a thing of beauty,a joy forever', a poet once said. It's the perfect balance of engineering and design. The noise it makes as it pulls away, sets my heart racing. A flash of Ferrari red and it's gone.[2] Fading light. The last gasps of the day. On Earth, colours lose their hold as the sky above drains them. Crimson, rose, blood red. On Earth, I watch in amazement. The sun takes its farewell and dips behind the horizon. I leave, wondering what new beauties the day to come will bring[3] He turns, he stops, he turns and runs, he stops and turns againNo two moves are the same.He looks up, he looks down.He looks forward, he looks round.Will he pass? Will he shoot? Will he turn again?[4] As I watch my cat feed her hungry kittens, all eight of them, each fighting for a space, I think about the miracle of life---how well it all works, how well it all fits together. Does anything get perfect?[5] I'm sitting here, head in hand. There is no room left in my head. It's ready to explode.And then the bell sounds, loud and welcome. The sound echoes... echoes through the corridors.Happy children put downtheir pens and wait for the words, simple but beautiful:'Off you go.'[6] I live by the sea. Where else is there to live? The sea fills my heart with joy. A big blu expanse of happiness, The crashing waves, obeying no one, come and then go. I always return to the sea. It knows the answers before I even ask the questions[7]'Hello,I'm home.'It brings a smile to my face when I hear my wife's voice.I look up and she's there. Has she walked out of a painting? She is beauty,' is all I think.60. Which of the following phrases fits best in the blank of the first paragraph?A.define beautyB.write a poemC.recommend a songD.describe creativity61.Which two posts above both talk about nature?A.Post 1 and Post 7.B.Post 2 and Post 6.C.Post 2 and Post 3.D.Post 4 and Post 7.62. In Post 5, the writer is actually talking about_.A.his/her noisy kidsB.the power of musicC.a terrible explosionD.the time when school is over(C)For the most part, it seems, workers in richer countries have little to fear from globalization. And a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich-country counterparts tobenefit，because they have less to lose and more to gain Traditional economics takes an optimistic line on integration(整合）and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labour have already been used up. If poor countries lower their barriers to trade and investment, as the theory goes, rich foreigners will want to send over some of their capital.If this inflow of resources arrives in the form of loans or portfolio investment(组合投资）,it will top up domestic savings and loosen the financial restriction on additional investment by local companies. If it arrives in the form of new foreign-controlled operations, FDI, so much the better this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investment ought to push incomes up, partly by raising the demand for labour and partly by making labour more productive.This is why workers in FDI-receiving countries should be in an even better position to profit from integration than workers in FDI-sending countries. Also, with or without inflows of foreign capital, the same gains from trade should apply in developing countries as in rich ones. The gains from trade logic often arouse suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets through trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all thesetrades, both sides-exporters and importers,borrowers and lenders, shareholders and workers can gain.63. Why are workers in poor countries more likely to benefit from the process of globalization?A. They can get more financial aidB . They have nothing to loseC. They have less to lose and more to gain.D. They can get more chances to gain a good job.64. What can be the final result of the inflow of the resource?A. It will top up domestic savings.B. It will loosen the financial restriction.C.It will push people's incomes up.D. It will bring technology and skills from abroad.65. What can we know from the last paragraphA.Poor countries get the most profit during the process of trade.B. Rich countries get profit from trade at poor countries' expense.C.Poor countries get more profit from trade than rich ones.D.All aspects involved in the trade can get benefit.66. Which can be the most appropriate title for this passage?A.Benefited or HurtB.Who Benefits the MostC.Helping the PoorD.The Inflow of ResourcesSection C(8%)Directions: Complete the following passage by using the sentences given below. Each sentence can be used only once. Note that there are two more sentences than you need.A. What we wear can reflect our skin colour.B. Other participants wore their normal clothes.C. The clothes we wear can affect our behavior.D. Some experts believe that the participants with white coats are more likely to be more creative.E. For example, we should choose a look that makes us feel more creative and happy.F. Galinsky and Adams think that the white coats made the participants feel more confident and careful .The science of styleDeciding what to wear in the moming is a challenge for some people. We often worry about what others will think of us because of our clothes. But researchers are beginning to think that our wearing has an equally powerful effect on how we see ourselves.Scientists Adam Galinsky and Hajo Adams report that there is science behind our style. In their research, Galinsky and Adams had some participants wear white lab coats similar to the ones scientists or doctors wear. ____67______The participants took a test that measured theirability to pay attention. The people wearing the white coats performed better than the people in regular clothes.____68____The researchers also believe that other kinds of "symbolic" clothescan influence the behavior of the people wearing them. A police officer's uniform or a judge's robe, for example, increases the wearer's feeling of power or confidence. And in workplaces that have a dress code,"symbolic"clothes may also affect how well employees do their jobs.Fashion blogger Jessica Quirk believes that our clothes greatly affect how we feel about ourselves. On her blog called"What I Wore," Quirk posts a photo of what she's wearing every day.She says that people should pay more attention to what they wear_____69______ One way to do this at work is to "dress up for the exciting job we want," she says, "not the boring job we have."Another way is to wear special clothes that mean something to us. For example, Quirk wears one pair of shoes to all her important meetings. They are her "lucky" shoes.As Quirk points out-and as researchers have discovered-our clothes are "like our second skin."___70____They can also tell the world something about us, without us having to say a word.IV.Summary Writing(10%)Directions: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible.It's not piano lessons or dance classes. Nowadays, the biggest extra-curricular activity is going to a tutor. "I spend about 800 Canadian dollars a month on tutors. It's costly," says Pat, a mother in Canada. However, she adds, "after finding out half my daughter's class had tutors, I felt like my child was going to fall behind because everyone else seemed to be ahead."Shelley, a mother of three, also has tutors constantly coming in and out of her home. "When I used to sit down with my children, it was hard to get them focused. I was always yelling. When I got a tutor once a week, they became focused for one entire hour and could get most of their homework done."Tutoring isn't simply a private school phenomenon. Nor is it geared(适应，满足）only toward lower-achieving students. In Canada alone, seven percent of high school students reported using a tutor in 2010. That increased to 15 percent last year.Overall, parents hire tutors because they are worried schoolsare not meeting their expectations, but there is also a cultural shift. A special value is placed on education in Asia, where tutoring is viewed as an extension of the school day. As a large number of Asians emigrated to the West over the recent years, their attitudes towards education have had an impact.Another reason for the growth in business is parental frustration and their packed schedules. "A lot of parents just don't have time to help their children with homework," says Julie Diamond,president of an American tutoring company."Others couldn't help their children after Grade 3."There has been a shift in the attitudes, too. "Children used to get bullied for having a tutor,"Diamond says. "Now it's becoming the norm to have one."Children don't seem to mind that they have a tutor. One parent feels surprised that so many of her child's classmates have tutors. "For the amount we pay in tuition, they should have as much extra help as they need," she says. Still, she's now thinking of getting a tutor. Why? Her daughter has actually asked for one.V.Translation(15%)Directions: Translate the following sentences into English, using the words given in the brackets.72、你越努力，收获就会越大。
