七、信息还原。
阅读下面短文，从短文后所给选项中选出能填入空白处的最佳选项，使短文通顺连贯，其中有两项是多余选项。
Chinese zhusuan is a time-honoured practice of performing calculations (计算) with an abacus.
1 It shows the creativity and wisdom of the Chinese people over thousands of years. In 2013, it was added to UNESCO's Representative List of the Intangible Cultural Heritage of Humanity.
2 People use defined formulas (公式) to move beads (有孔的珠子) on the abacus for all kinds of Maths problems, from simple addition to complex equations (方程式). Beginners can perform quick calculations after some basic training.
Since 1979, abacus associations have been set up in China. 3 And various zhusuan competitions have been organized. In 2008, zhusuan became a national intangible cultural heritage.
Although modern electronic devices have replaced the abacus for daily calculations, zhusuan still has great value. It helps improve children's attention, memory and thinking skills. Having been passed down for generations, it has helped form a strong sense of China's cultural identity (认同感). 4
Today, many places are working to protect and promote the value of traditional calculation techniques.
5 Some schools have zhusuan courses or exhibition halls. Teachers are trying new ways to combine zhusuan with modern Maths, hoping more people will learn and love this traditional Chinese skill.
A. Certain rules have been developed to test zhusuan skills.
B. In Chinese, zhusuan directly means calculating with beads.
C. It is widely considered as one of the great inventions of China.
D. And it has also become an important symbol of Chinese culture.
E. Electronic calculators are now widely used to teach zhusuan in schools.
F. There are over 20 museums or exhibition halls about zhusuan in China.
G. It was first created by ancient Chinese scientists during the Tang Dynasty.

【分析】
这是一篇介绍中国珠算的信息还原类题目，解题时首先通读全文，明确文章围绕珠算的历史定位、操作逻辑、发展历程、当代价值与推广举措展开，再逐空结合上下文的语义逻辑匹配选项：
1. 第1空前文刚引出珠算是历史悠久的算盘计算技艺，后文点明它承载了中国人数千年的创造力与智慧，需要一个承上启下的评价类表述衔接前后。
2. 第2空后文详细介绍人们套用规定公式、拨动算珠完成各类数学计算的操作方式，空缺处需要对应引出珠算的核心含义，和后文的操作说明形成呼应。
3. 第3空前文提到国内陆续成立珠算协会，后文提到各类珠算赛事被举办，空缺处要补充协会成立后推出的相关配套举措，衔接前后内容。
4. 第4空前文并列介绍了珠算锻炼孩子思维能力、塑造国民文化认同感两方面的价值，空缺处需要继续延伸珠算的文化价值，和前文的价值表述形成顺承并列。
5. 第5空前文点明当下各地都在保护推广珠算这类传统计算技艺，后文提到部分学校开设珠算课程、设置展厅，空缺处要列举推广珠算的相关落地成果，保证前后语义连贯。
【解析】
我们逐空推导匹配：
1. 第1空：前文介绍珠算的基本定义，后文夸赞珠算体现中国人数千年的智慧创造力，C选项“它被广泛认为是中国伟大的发明之一”，既承接前文对珠算的定性，又引出后文对其价值的阐述，逻辑完全匹配。
2. 第2空：后文详细讲解珠算的操作方式是拨动算珠完成计算，B选项“在中文里，珠算直接的含义就是用算珠进行计算”，刚好解释珠算名称的含义，自然引出后文的操作说明，衔接通顺。
3. 第3空：前文提到国内成立了诸多珠算协会，后文说明各类珠算比赛陆续举办，A选项“人们制定了特定的规则来考核珠算技能”，是协会成立后推出的配套安排，为后续举办赛事提供了基础，逻辑连贯。
4. 第4空：前文已经介绍了珠算锻炼思维、塑造文化认同感的价值，D选项“它也已经成为中国文化的重要象征”，和前文的价值点并列延伸，进一步点明珠算的文化地位，符合行文逻辑。
5. 第5空：前文提到各地正在保护推广珠算技艺，后文提到学校开设珠算课程、设置展厅，F选项“国内有超过20座珠算相关的博物馆或展厅”，属于推广珠算的落地成果，和后文学校的相关举措并列，语义通顺。
【答案】
1. C 2. B 3. A 4. D 5. F
【知识点】
语篇逻辑衔接；信息还原；传统文化常识
【点评】
本题以中国非物质文化遗产珠算为主题，既考查学生对信息还原类题型上下文语义关联的把握能力，也渗透了中国传统文化相关的文化常识，干扰项区分度较高，只要顺着行文逻辑逐一匹配前后内容，很容易排除多余选项得到正确答案。
