Is it possible that you’ve been looking at math in the wrong way? With International Day of Mathematics coming on March 14, we interviewed Li Xing a math professor at Ning Xia University. We asked if math can be beautiful and fun. Here’s what Li said. Numbers are beautiful Many people today want to have beautiful looks. But there is math hidden in beautiful human bodies. Measure the length from your head to your belly button (肚脐眼) and from your belly button to your feet. The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings. In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, “I’ve sailed a thousand miles through Gorges in a day”, “My boat has left ten thousand mountains far away”. “A thousand miles in one day”, “ten thousand mountains”—all these numbers show how fast Li Bai traveled and how happy he felt. Numbers give us the freedom to imagine. Curves are beautiful Sine curves (正弦曲线) are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving. The tangent curve (正切曲线) is like a waterfall. That’s really “dashing down three thousand feet from on high”. If you do a math problem and get that curve, you’ll feel amazing! Formulas(公式) are beautiful In a right-angled triangle, the square of the longest side is equal to the sum of the squares of the other two sides, neither more nor less. How neat! Just as Chinese—American mathematician Chern Shingshen said, “Math is fun!” 1．If the ratio of two numbers is around 0.618,  ________. A．it may show us a golden color B．it will look like a human body C．it might bring people a sense of beauty D．it is as long as the length from a man’s belly button to his feet 2．From the poem of Li Bai in this text, we can know that _______. A．Li Bai was good at counting numbers B．Li Bai used numbers to show his feelings C．Li Bai succeeded in solving math problems D．Li Bai loved traveling by boat along the river 3．What does a waterfall usually look like in a math way?  ________ A． B． C． D． 4．What does the underlined word “equal” mean in Chinese?  ________ A．等同的 B．整体的 C．类似的 D．平均的 5．What is the text mainly about?  ________ A．The life of a math professor. B．The International Day of Mathematics. C．Why math is beautiful and fun. D．How math helps us live a better life. The China International Big Data Industry Expo 2022 (大数据工业博览会) was held online in Guiyang on May 26. More than 100 famous companies from China, Germany, Japan and other countries attended the expo on “cloud”. You may have heard a lot about word “cloud”. The name might make you think that it’s just like real clouds. But in fact, it is not the clouds in the sky but the “cloud” that saves your photos, emails, movies, music and so on. The “cloud” is made of millions of hard drives ( 硬盘), computer servers ( 服务器) and underground cables (电缆). When you open a website online, you are actually asking a server to give you data (数据). And the data may transmit thousands of kilometers from a data center to your computer, through underground cables. Where are these data centers? In China, most are now in big cities like Beijing, Shanghai and Guangzhou. They take up lots of land and energy. Recently, China has made plans to build 10 data center groups in right areas. Many are in western and northern parts of China like Gansu and Guizhou. There is more land in these areas. They also have more green energy, like wind and solar energy. This can make the data centers more environmentally friendly. Building data centers can help the development of these areas. Nowadays, big data has become a key industry in Guizhou. 1．What does the “cloud” help people do? A．Changing the weather. B．Taking photos. C．Saving data. D．Opening a website. 2．What is the “cloud” made of? a. computer monitors    b. hard drives    c. computer servers    d. underground cables A．abc B．abd C．bcd D．acd 3．What’s the Chinese meaning of the underlined word “transmit” in Paragraph 3? A．传输 B．接收 C．复制 D．记录 4．Why is data center built in Guizhou? A．People in Guizhou are friendly. B．The environment here is well protected. C．There is more land and green energy. D．Guizhou is very beautiful and colorful. 5．What can we know about data centers according to the text? A．They don’t need a lot of energy. B．Data centers can help cities to develop. C．Most of them are in the south of China. D．There are only 10 data centers in China. Big data (大数据) is a lot of sets of information that are put together so they can be used by a computer program. The computer program looks for different kinds of answers or patterns (样本) in the data. Big data can have different kinds of information from many sources (来源), such as information that comes from schools, social media sites, companies and governments. One set of data can have people’s names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the computer. Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra help in class. The teacher can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream. Big data can be used for good reasons. Some hospitals use big data to predict (预测) if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby, so he or she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong. How can big data be used for good and bad things? It is because the computer programs which is used to look at big data and understand it are written by people. People think in a certain way. Because they think in a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people. 1．What is the first paragraph about? A．What big data is and how it is used. B．Why we can use big data in a number of ways. C．Where important data is collected and stored. D．What big data is and how it is collected. 2．One company uses weather information to ________. A．understand when people will need ice cream B．know when people will visit the hospital C．find out who rides the bus or train D．help children in nee 3．The main idea of Paragraph3 is ________. A．big data can be used for good reasons B．we can use big data in a number of ways C．big data can be used for both good and bad reasons D．we can use big data to prevent babies from getting sick. 4．What can we infer (推断) from the reading? A．If there is plenty of information, it is called big data. B．Big data provides any information for the government. C．We should make full use of big data to serve (服务) the society. D．Big data only collects the latest information from the world. 5．The overall tone (总基调) of this reading is ________. A．sad and personal B．scientific (科学的) and informative (提供信息的) C．informative but silly D．personal and scientific Can you say the meaning of “Zero”? Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2,4, 6 and 8) and odd numbers (ending in 1,3, 5, 7 and 9). Some Australian scientists put up different cards with an odd or even number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 1．How does the passage start? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 2．Which of the following card should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 3．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than bees. B．Bees like bitter water rather than sugar water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 4．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers D．Scientists know why bees can tell different numbers. In Western countries, some people think the number 13 brings bad luck. In the past, a lot of tall buildings didn’t even have a 13th floor. However, there aren’t really any other numbers that are special in this way in the West. There are superstitions (迷信) about some numbers in China as well. For example, the number “4” is said to be unlucky because it sounds like the Chinese word for “death”. But that’s just one small example of China’s obsession (迷恋) with numbers. When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. Because Chinese characters (文字) cannot be used for website addresses. They can only use numbers or the letters of the Roman alphabet. In pinyin, the telecom company China Unicom is called Zhongguo Liantong. If the company used their pinyin name for their website address, it would be quite long. So instead, they use their customer service hotline number —10010. com. This is easier to type and remember. In addition, the pronunciations (发音) of some numbers sound similar to other words in Chinese. This makes for some clever wordplay. For example, the numbers “5-2-0” in Chinese sound similar to the pronunciation of the Chinese phrase “I love you”. Many couples choose to get married on May 20 for this reason. It is interesting to see how Chinese people have used numbers in so many different ways. “88” for now! 1．Which number do some people in Western countries think is unlucky? A．2. B．4. C．5. D．13. 2．What surprised the writer when he came to China? A．4 is an unlucky number in China. B．China regards 13 as an unlucky number. C．Some tall buildings don’t have a 13th floor in China. D．China uses numbers in website addresses. 3．What’s the website address of the telecom company China Unicom in the passage? A．Zhongguoliantong. com. B．TCCU. com. C．10010.com. D．TelecomChina. com. 4．Why do many couples in China choose to get married on May 20? A．Because the weather is usually good on that day. B．Because it always falls on a weekend. C．Because 5, 2 and 0 are all lucky numbers in China. D．Because its Chinese pronunciation is similar to “I love you”. 5．What’s the best title of this passage? A．China loves numbers B．The special numbers in West C．Lucky number in China D．Lucky number in Western countries I used to believe that only words could catch the spirit of the human soul. There were such stories that shaped the way we saw the world. Words were everything. That belief changed. In an ordinary math class, my teacher raised a simple question: What’s 0.99 rounded (四舍五入) to a whole number? Easy. When rounded to a whole number, 0.99=1. Somehow, I thought even though 0.99 is only 0.01 away from 1, there’s still a 0.01 difference. That means even if two things are only a little different, they are still different, so doesn’t that make them completely different? My teacher answered my question by giving another equation (等式): 1=0.9, which could also be expressed as 1=0.999999...repeating itself without ever ending. There was something mysterious but fascinating about the equation. The left side was unchangeable. On the right was something endless, a number repeating itself limitless times (无限次). However, in a certain way, these two different things were connected by an equal sign. Lying in bed, I thought about how much the equation is parallel to our life. The left side of the equation shows that sometimes life itself is so unchangeable and so clear. The certain, whole number of the day when you were born and the day when you would die. But then there is that gap in between life and death. The right side means a time and space full of limitless possibilities, and endless chances into the open future. So that’s what life is. Objective but imaginative. Unchangeable but limitless. Life is an equation with two sides that balances itself out. Still, we can’t ever truly seem to put the perfect words to it. So possibly numbers can express ideas as words can. For now, let’s leave it at that: 1=0.999999...and live a life like it. 1．What is paragraph 1 mainly about? A．Words have a long history. B．Words express a lot. C．There are different kinds of words. D．There are many sounds of a word. 2．Why does the writer think the equation is mysterious but fascinating? A．Because it has an endless repetition. B．Because nobody else but the teacher knows it. C．Because it shows two different numbers can be equal. D．Because it is the hardest math question the writer has met. 3．Which of the following underlined parts has a similar meaning to “is parallel to”? A．I love my teacher. He is like a father to me. B．Our actions can make a difference and lead to a better future. C．A happy childhood has nothing to do with new developments in technology. D．I find it difficult to remember everything, but I’m gradually getting used to it. 4．What is the best title for the passage? A．The Powerful Word B．The Perfect Equation C．An Unforgettable Question D．An Excellent Teacher In the last century, different natural disasters have robbed several cultural heritage (遗产) from us. On WeChat, some people say, “What a pity that we cannot see the damaged parts of the wonders anymore.” But people can see them in a new way—through a video game. In this game, the player can travel to one city after another and enter the buildings exactly like they are in reality, and see the wonders as they were before the fire. Maybe digital technology (数字技术) could help protect cultural heritage better. This idea dates back to the 1990s and the necessary technology has continued to develop since then. By scanning (扫描) the ancient buildings, building 3D models, as well as measuring everything, scientists can make a copy exactly as the real one. As computers and smart phones are popular, the digital copy has great value. First, it allows tourists to feel the cultural heritage without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes (敦煌石窟) is a good example of this as tourists can view the paintings without standing near them. Second, it can make the cultural heritage more famous by spreading information about them through the Internet. In 2000, a virtual tour of the Dunhuang Grottoes became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years. Last, it stores all the information of the cultural heritage. Even if the real ones are damaged one day, people can still know what they were like and can build a new one if wanted. Of course, however exact a model is, it is not the real one. Maybe we will have better technologies in the future, but the digital technology offers a practical way to protect cultural heritage at the moment. 1．We can see the damaged parts of those wonders ________. A．by entering the buildings B．through a video game C．by spreading information D．by creating another copy 2．Which is the correct order of digitalizing ancient buildings according to the passage? ① Build 3D models. ② Measure everything. ③ Scan the ancient buildings. ④ Make a copy exactly as the real one. A．②①④③ B．③①②④ C．①②④③ D．②③①④ 3．The writer uses the example of Dunhuang in Para. 3 and 4 to ________. A．show the writer is really interested in travelling to Dunhuang B．prove people can build a new one if the real ones are damaged C．show Dunhuang Grottoes are disappearing because of the disaster D．prove computers and phones makes digital copies more valuable 4．What is the writer’s attitude (态度) towards the digital technology? A．Positive. B．Negative. C．Disappointed D．Uncertain. 5．What is the best title of the passage? A．The cultural heritage. B．The damaged parts. C．The digital technology. D．The Dunhuang Grottoes. Beep! Beep! Barcode (条形码) technology makes it faster and easier to buy things in stores. This year, this great invention is 50 years old! Time has proved it to be a great invention. Before this, cashiers (收银员) had to ring up prices by hand. What information does a barcode include? Where the product comes from, where it has been, its price, expiration date … you name it. It can also help stores record their products. For example, if there are 10 boxes of milk and a customer buys one, it will be recorded so that the store owner knows there are nine boxes left. “ Its creation allowed the first digitalization (数字化) in the control of the stock (库存) , ” Jose Maria Bonmati from AECOC, a Spanish commercial association, told EL Mundo. The next generation of barcodes, such as QR codes, can hold more information. “ They can tell consumers if a product contains allergens (过敏原) or if it is organic (有机的) . This provides consumers with a greater level of trust in products they buy, ” said GSI, an organization that develops global barcode standards. 1．What can we know about barcodes? ________ A．They were first used to buy things. B．They were invented fifty years ago. C．They were used to control the stock. D．They were designed by a cashier from a store. 2．What is Paragraph 2 mainly about? ________ A．What barcodes can be used for. B．What barcodes can help customers do. C．How widely barcodes are used. D．How information is stored in barcodes. 3．According to Jose Maria Bonmati, barcodes ________. A．make cashiers’ work easier to do B．improve the level of trust in the products C．help companies better manage their stock D．tell consumers more about the products they buy 4．What can we know from the last paragraph? ________ A．The importance of barcodes still needs to be proven. B．GSI is the next generation of barcodes. C．GSI is developing a new type of barcode. D．QR codes are more consumer - friendly. 5．Which word might the writer use to describe barcodes? ________. A．Doubtful B．Beautiful C．Convenient D．Uncertain Which zodiac sign（星座）is the most competitive in the Olympic Games? The site RunRepeat did a survey to find out. It turns out that Capricorns are the ones to beat, as 854 of them have won 1,202 medals. The combined（合起来的）average（平均数）of medals for all other zodiac signs is 757. Capricorns earned 58.6 percent more medals than that. They are said to be career-driven（事业⼼强的）and hard-working.

Can you do it in English, or do you have to use your first language? Do you count on your fingers? Many people think that numbers and math are the same all over the world. But scientists have discovered that it is not true. People in different parts of the world use different ways to count on their fingers. In the United States, people begin counting with their first finger. They then extend the rest of their fingers and finally the thumb to count to five. Then they repeat this with the other hand to get to ten. In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand. Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. Some languages have only a few words for numbers, and others have no words for numbers. For example, the aboriginal people in Australia don’t have hand movements to stand for numbers. They don’t even have words for numbers. However, they are still able to understand different ideas about numbers. Similarly, people of the Piraha tribe in northwestern Brazil don’t have words for numbers such as “one” or “three”. They are not able to say “five trees” or “ten trees” but can say “some trees”, “more trees” or “many trees”. Professor Edward Gibson from the Massachusetts Institute of Technology said that most people believe that everyone knows how to count, “But here is a group that does not count. They could learn, but it’s not useful in their culture, so they’ve never picked it up.” 1．Why does the writer list the four questions at the beginning of the passage? A．To make a survey. B．To interest the readers. C．To give examples. D．To interview the readers. 2．According to Paragraph 2, what is the difference between the US and China in finger counting? A．People from China use finger positions to do counting. B．People from the US usually begin counting with their thumb. C．People from China count much faster than people from the US. D．People from the US use only one hand to count from one to ten. 3．People of the Piraha tribe are from ________. A．the US B．Brazil C．Australia D．Asia 4．Which of the following is TRUE about aboriginal Australians? A．There are ideas of numbers in their life. B．There is no “some trees” in their language. C．They have only a few words for numbers. D．They have hand movements for numbers. 5．What’s the main idea of the passage? A．Chinese people are good at counting. B．Counting quickly on fingers is not easy. C．Counting is difficult to learn in some tribes. D．People don’t need numbers in some cultures. Many of us may have experienced the pleasant moment of seeing recommended (推荐) songs after we listen to some songs on a music app. When we open shopping websites, we often see things we want to buy on the home page. The businessman can decide which is the best place to build a new entrance in a big supermarket in the city center. If you want to take a taxi on a taxi app, it can even guess where you want to go before you tell it! Aren’t these things amazing? This is based on data (数据). Data is no longer only about numbers, but information from almost every side of our lives: our shopping habits, interests or what we eat. All of this is called “big data”. In December 2017, President Xi Jinping called for China to speed up its big data strategy (战略) to better serve social development. As a result, people’s lives can be improved as well. He also asked for greater use of big data in areas like education, and transportation. We have seen big data being used more often in China in the past few years. The role it plays in travel is just one example. Many travelers today like to share their experiences with others on the Internet. All the data that travelers share online is helping the tourism industry get a lot of information. After the data is analyzed (分析), these tour sights can know about travelers’ needs better. In this way, services will be improved, which is helpful to the development of the whole industry. As a result, travelers can expect better tours in the future. Moreover, big data is also an important growth tool for trade. With growth rate of 30 percent every year, sales of big data industry in China will reach one trillion (万亿) yuan yearly by 2020. Having so many good influences, big data is sure to be seen more and more in China. 1．According to Paragraph 1, big data can help people ________. A．buy songs from a music app B．design home pages for websites C．take a taxi without paying for it D．make better decisions in business 2．According to Paragraph 2, President Xi Jinping’s attitude towards big data is to ________. A．improve people’s shopping habits B．use the big data in education C．use the big data in medicine D．use the big data in safety of society. 3．After reading the passage, we know that ________. A．the speed of big data development in China now is enough B．people have few chances to use big data at present in China C．big data improve people’s life better D．big data is just sure to be seen more and more in education 4．What can be the best title for the passage? A．Big Data Brings Good Songs B．Big Data Influences China C．Tourism Gets Help from Big Data D．Sales of Big Data Industry in China VISIT THE LIBRARY WITHOUT LEAVING HOME Ask for a library card with simply E During our period of closure, New Yorkers can ask for a library card through Simply E and use a large of digital resources (数学化资源).

The computer program looks for different kinds of answers or patterns（模式） in the data. Big data can have different kinds of information from many sources, such as information that comes from schools, social media（媒体）sites, companies, and governments. One set of data can have people’s names and addresses. Another set can have what they like, where they go, and how much time they spend on the computer. Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra（额外的）help in class. The teachers can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream. Big data can be used for good reasons. Some hospitals use big data to predict（预测）if a baby who was born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong. How can big data be used for good and bad things? It is because the computer programs used to look at big data and understand it are written by people. People think in a certain way. Because they think a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people. 1．What does the underlined word “sources” in Paragraph 1 mean? A．Schools that you come from. B．Places that you get things from.

But how about making one disappear? A new report said a long time of climate(气候) change could do that. It also said Tuvalu would be the first country to be completely lost because of climate change. Tuvalu, a Pacific island country with many small islands, is near Australia, lying in the South Hemisphere(南半球) and there are only 12,000 people in this country. Now, 40 percent of the area in its capital is underwater. ▲ . They don’t want to lose their country, so they plan to build a new one in the metaverse(元宇宙). It is a digital(数字化) country that only shows online. No matter where Tuvalu people live in the real world, they will still have their nationality(国籍) and “live” in its online country. For example, if a Tuvaluan misses the beautiful butterflies and the soft wind in their hometown, he can enter their digital country online and enjoy them. This news made people in Tuvalu excited. But Li Zuxi, a director of the metaverse lab, said, “Though the digital country belongs to Tuvalu, it’s built on a metaverse platform(平台). Now, the metaverse is not perfect, which may bring some problems. He gave us an example. If someone from other countries enters the space of the digital country, how can the system tell if the person truly belongs to that country. In such situations, the safety of this digital country can’t be made sure of.” However, many island countries disagree with Li Zuxi. They say that building a digital country may be new, but this is the only way for people in those island countries to be connected. Why not have a try? Actually, whether people will build it or not, saving the real world and creating a better living environment should be paid the most attention to. 1．From the picture, Tuvalu lies in the place of ________. A．L1 B．L2 C．L3 D．L4 2．Which sentence can be put in the ▲ ? A．The government of Tuvalu hasn’t done enough to save the country B．Whether the country will disappear depends on how Tuvalu people protect the environment C．People from all over the world are trying to save Tuvalu from disappearing D．Facing the disappearing of their country, all Tuvalu people are so sad 3．From Li Zuxi’s words, we can infer that ________. A．the digital country in the metaverse is perfect enough now B．there is a long way to go if people want to build a country in the metaverse C．people can’t make sure of the safety of the digital country D．all the island countries are building a digital country in the metaverse 4．The structure of this passage is ________. (P1: Paragraph 1  P2: Paragraph 2…) A． B． C． D． On April 18th—the International Day for Monuments and Sites, China Daily’s digital employee Yuanxi and Dunhuang Mogao Grottoes’ official virtual (虚拟的) cartoon figure Jiayao together introduced an interactive digital platform (数字化互动平台) that hosts a virtual copy of the Mogao Grottoes’ Library Cave to the world. The platform was developed jointly by the Dunhuang Academy and the Chinese tech firm Tencent. It uses gaming technologies to show the historical scenes of the Library Cave in the digital world. The Library Cave in Mogao Grottoes was discovered in 1900, with more than 60,000 cultural relics dating from the 4th century to the 11th century unearthed. It was one of the most important archaeological discoveries in the 20th century. On the platform, visitors can role-play and “time travel” to ancient dynasties and talk with eight historical figures. The public can enter the platform through the Digital Dunhuang website and its WeChat mini program. In the digital age, the model of “culture+technology” has been adopted to promote (促进) the development of Chinese culture. The digitalization rate of China’s precious cultural relics has been more than 70 percent, according to the 2022 China Digital Collection Industry Research Report released by iResearch. The Ministry of Culture and Tourism has also encouraged the development and transformation (转型) of cultural intellectual property by digital means. CCTV (China Central Television) has created a series of digital collections with different Dunhuang themes, such as the Dunhuang divine deer Youyou. It was created based on the image of the nine-colored deer from Dunhuang murals. The public can see the divine deer on CCTV’s own digital platform. Digital collections cater to (迎合) the consumption habits of young people. They not only protect the intellectual property of the collections but also bring the public closer to China’s “excellent traditional culture”, noted Dunhuang Art Institute. Su Bomin, director of the Dunhuang Academy, told Xinhua that more efforts will be made to explore new forms for showing cultural relics and offer the public more immersive cultural experiences to develop Dunhuang culture. 1．On the Mogao Grottoes’ Library Cave, visitors can ________. A．play role-playing games set in ancient times B．play video games named historical characters C．design digital caves showing historical culture D．talk to the designer of the digital Library Cave 2．What is the purpose of developing digital platforms for cultural institutions? A．To show the latest gaming technologies. B．To help cultural institutions make money. C．To promote the development of Chinese culture. D．To encourage people to explore new forms of digital collections. 3．What can we learn about the Dunhuang divine deer Youyou? A．It was one of the most important archaeological discoveries in the 20th century. B．It was created based on the image of the eight-colored deer from Dunhuang murals. C．The old people don’t like it. D．It can bring the public closer to the traditional cultural. 4．Which of the following would be the best title for the passage? A．Presenting Digital Collections B．Experiencing History Online C．Creating Mini Programs D．Introducing Gaming Technologies From November 1st to December 10th in 2020, China started its seventh national population census(普查). 7 million census takers have asked each family about their name, gender(性别), age, education, job and so on. This census is different from the ones in the past. For the first time, citizens were encouraged to use smartphones and other digital tools to record their information. China has a national population census every 10 years. The first one was done in 1953. At that time, there were about 600 million people in China. But China’s population has boomed. It was about 1.37 billion in 2010. For the 2020’s national population census, all people of China were included in the census. But Chinese citizens who had settled(定居) abroad and foreigners who were staying in China on either business or tourist visas(旅游签证) were not counted. “The census is very important for every citizen,” said Ning Jizhe. “It will help improve infrastructure(基础建设) and public services. For example, if census results show that there are many children living in an area, the government will know that it should build more schools there.” Scientists can also learn more about population growth from the census. In some years, the population grows faster than in others. Even in the same year, population growth is different in different places. Scientists can use the information to find out what causes growth in certain years and places. 1．Why was the 2020’s national population census different from others? A．China had the larger population in 2020 than in other years. B．The 2020’s national population census included people’s jobs and education. C．People could use digital tools to record their information in 2020. D．The 2020’s national population census took the shortest time. 2．The first national population census in China was done ________. A．in 1953 B．in 1964 C．in 2000 D．in 2010 3．What does the underlined word “boomed” in Paragraph 2 probably mean in Chinese? A．下降 B．包括 C．测量 D．增长 4．________ was included in the 2020’s national population census. A．Chinese people who are traveling abroad B．Chinese people who have settled in other countries C．Foreigners staying in China with business visas D．Foreigners staying in China for holidays 5．Why is the national population census important? A．Scientists can compare(比较) the population of China with the population of the world B．The government will build more schools. C．It is helpful to improve infrastructure and public services. D．The population in China grows faster than in other countries. How many digits of pi (圆周率位数) can you remember? Just 3.1415926? Well, this may not be good enough for scientists. Swiss researchers said they broke a new record. Using a supercomputer, they counted pi to 62.8 trillion (万亿) digits. The team, at University of Applied Sciences in Graubunden, Switzerland, took 108 days and nine hours to do this! It was “3.5 times as fast as the former world record in 2020”, which reached 50 trillion digits, according to the university. Researchers are waiting for the Guinness Book of Records to certify (认证) their efforts. Since it was first discovered and understood 4,000 years ago, humans have been trying to count pi as exactly as possible. Zu Chongzhi (429-500), a Chinese mathematician (数学家) , counted pi between 3.1415926 and 3.1415927. Nobody surpassed (超过) his results for about 1,000 years — until Al-Kashi, an Iranian (伊朗的) mathematician, counted it to 16 decimal places (小数位). Why do we need to know an exact value (数值) of pi? “It’s used everywhere, from the general relativity (广义相对论) of Einstein to your GPS to all kinds of engineering problems,” Jan de Gier, a math professor at the University of Melbourne, Australia, told The Guardian. It’s true that pi pops up everywhere. But is it too much to count it to 62.8 trillion digits? “I can’t imagine any real-life use where you would need any more than 15 decimal places,” said David Harvey from the University of New South Wales, Australia. However, De Gier compares this to the Olympic Games: “World records are not useful by themselves, but they set a benchmark (基准) and they teach us about what we can achieve.” “It’s a big challenge for computers,” Harvey agreed. “It’s really a difficult thing to do and it needs lots of math and computer science.” 1．What part of this story is news? A．An exact value of pi is used everywhere. B．The value of pi was counted to a further number. C．The former value of pi was proven to be incorrect. D．A supercomputer was developed in Switzerland. 2．The former Guinness record of the value of pi reached ________. A．7 decimal places B．16 decimal places C．50 trillion digits D．62.8 trillion digits 3．Paragraph 4 is mainly about ________. A．why we work on the value of pi B．how to find the value of pi C．the person who discovered pi D．the history of pi studies 4．Harvey agrees that ________. A．we only use pi in scientific studies B．pi is used everywhere in our lives C．we need a more exact value of pi D．it’s worthless to work on the value of pi 5．In De Gier’s opinion, to set a world record is ________. A．simple B．useless C．impossible D．meaningful How did the Maya count in ancient times? How many bags of corn did they have? How many did they sell? Did all the crops arrive at the city market? To answer these important daily questions, they used some numbers like this: The Maya was good at math. They counted in groups of 20, not 10. They wrote numbers in columns going up. The bottom row was the “ls” column, the next row up was 20s, then 400s, and so on. For numbers, they used a dot () for 1, a line for 5, and a shell () shape to show zero. Numbers 1 to 19 were written with a combination of lines and dots. Can you read the number in the following picture? It’s the number 1209(three 400s + no 20s + nine 1s). The Maya also kept three different calendars. The first divided the year into 18 months of 20 days each, plus a short month of 5 days. The short month was believed to be unlucky, a time when spirits walked. The second calendar repeated every 260 days. This was used to plan religious activities. When talking about events long ago, they used a calendar called “the long count.” This had a span of about 5,136 years. Year 1 on this calendar was 3114 BCE on our calendar. Each city and village had a calendar keeper, who was in charge of saying when to celebrate holidays and when to expect rain or plant crops. But farmers could probably also tell the time of the year from the sun and stars. 1．The Maya created their way of counting mainly to ________. A．celebrate local holidays B．plan religious activities C．keep different calendars D．solve everyday problems 2．According to Maya math, the number in Picture ________ is equal to “414”. A． B． C． D． 3．Which of the following about Maya calendars is TRUE? A．Three kinds of calendars were used for different purposes. B．The first calendar was usually used to plan religious activities. C．“The long count” calendar had a history of about 3,114 years. D．The short month in the first calendar was thought to bring good luck. 4．What’s the main idea of the passage? A．The development of numbers and calendars in Maya. B．The introduction of the Maya numbers and calendars. C．The situation of Maya numbers and calendars nowadays. D．The difference between numbers in Maya and other places. 2 同步新教材，周周有练习，月月有重点！ 7 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $$ 2024-2025学年一线教师制作精品新课系列资料，已编校！ 2024-2025学年一线教师制作精品新课系列资料，已编校！ Unit4 Numbers 单元话题（数据与数字）阅读理解进阶练18篇 You may feel that math is hard and boring. Is it possible that you’ve been looking at math in the wrong way? With International Day of Mathematics coming on March 14, we interviewed Li Xing a math professor at Ning Xia University. We asked if math can be beautiful and fun. Here’s what Li said. Numbers are beautiful Many people today want to have beautiful looks. But there is math hidden in beautiful human bodies. Measure the length from your head to your belly button (肚脐眼) and from your belly button to your feet. The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings. In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, “I’ve sailed a thousand miles through Gorges in a day”, “My boat has left ten thousand mountains far away”. “A thousand miles in one day”, “ten thousand mountains”—all these numbers show how fast Li Bai traveled and how happy he felt. Numbers give us the freedom to imagine. Curves are beautiful Sine curves (正弦曲线) are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving. The tangent curve (正切曲线) is like a waterfall. That’s really “dashing down three thousand feet from on high”. If you do a math problem and get that curve, you’ll feel amazing! Formulas(公式) are beautiful In a right-angled triangle, the square of the longest side is equal to the sum of the squares of the other two sides, neither more nor less. How neat! Just as Chinese—American mathematician Chern Shingshen said, “Math is fun!” 1．If the ratio of two numbers is around 0.618,  ________. A．it may show us a golden color B．it will look like a human body C．it might bring people a sense of beauty D．it is as long as the length from a man’s belly button to his feet 2．From the poem of Li Bai in this text, we can know that _______. A．Li Bai was good at counting numbers B．Li Bai used numbers to show his feelings C．Li Bai succeeded in solving math problems D．Li Bai loved traveling by boat along the river 3．What does a waterfall usually look like in a math way?  ________ A． B． C． D． 4．What does the underlined word “equal” mean in Chinese?  ________ A．等同的 B．整体的 C．类似的 D．平均的 5．What is the text mainly about?  ________ A．The life of a math professor. B．The International Day of Mathematics. C．Why math is beautiful and fun. D．How math helps us live a better life. 【答案】1．C 2．B 3．C 4．A 5．C 【导语】本文是一篇说明文。文章主要介绍了数学的美和趣味性，呼吁人们改变对数学的看法，更全面地认识它。 1．细节理解题。根据“The ratio (比例) of these two numbers is always around 0.618...music and paintings.”可知，这两个数字之间的比例总是在0.618左右，这是黄金比例，比如在大自然、音乐和绘画中随处可见。所以物体比例约为0.618时，选项C“它可以给人们带来美感”符合题意。故选C。 2．细节理解题。根据“all these numbers show how fast Li Bai traveled and how happy he felt.

More than 100 famous companies from China, Germany, Japan and other countries attended the expo on “cloud”. You may have heard a lot about word “cloud”. The name might make you think that it’s just like real clouds. But in fact, it is not the clouds in the sky but the “cloud” that saves your photos, emails, movies, music and so on. The “cloud” is made of millions of hard drives ( 硬盘), computer servers ( 服务器) and underground cables (电缆). When you open a website online, you are actually asking a server to give you data (数据). And the data may transmit thousands of kilometers from a data center to your computer, through underground cables. Where are these data centers? In China, most are now in big cities like Beijing, Shanghai and Guangzhou. They take up lots of land and energy. Recently, China has made plans to build 10 data center groups in right areas. Many are in western and northern parts of China like Gansu and Guizhou. There is more land in these areas. They also have more green energy, like wind and solar energy. This can make the data centers more environmentally friendly. Building data centers can help the development of these areas.

The computer program looks for different kinds of answers or patterns (样本) in the data. Big data can have different kinds of information from many sources (来源), such as information that comes from schools, social media sites, companies and governments. One set of data can have people’s names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the computer. Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra help in class. The teacher can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream. Big data can be used for good reasons. Some hospitals use big data to predict (预测) if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby, so he or she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong. How can big data be used for good and bad things? It is because the computer programs which is used to look at big data and understand it are written by people. People think in a certain way. Because they think in a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people. 1．What is the first paragraph about? A．What big data is and how it is used. B．Why we can use big data in a number of ways.

Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2,4, 6 and 8) and odd numbers (ending in 1,3, 5, 7 and 9). Some Australian scientists put up different cards with an odd or even number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 1．How does the passage start? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 2．Which of the following card should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 3．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than bees. B．Bees like bitter water rather than sugar water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 4．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers D．Scientists know why bees can tell different numbers. 【答案】1．C 2．B 3．D 4．A 【导语】本文是一篇说明文。文章主要讲述了蜜蜂经过训练后可以学会数字并有很强的数学能力的内容。 1．细节理解题。根据“Can you say the meaning of “Zero”? Can you do addition and subtraction? Most people can. But do you know bees can do these things too?”可知，你知道零的意义吗？你会做加减法吗？你知道蜜蜂也能做这些事情吗？所以，文章是通过问问题的方式开始的。故选C。 2．细节理解题。根据“the second group to choose even numbers”可知，第二组选择偶数，题干中图②数字4为偶数，图③数字6为偶数，所以②③符合原文。故选B。 3．细节理解题。根据“After some training, they can know the difference between even numbers and odd numbers.”可知，经过训练蜜蜂可以知道偶数和奇数之间的区别。故选D。 4．推理判断题。根据最后一段内容可知，蜜蜂的大脑比我们小约86000倍，却能这么快学会数字，可见其有超强的数学能力。选项A“蜜蜂具有很强的学习数字的能力”符合原文内容。故选A。 In Western countries, some people think the number 13 brings bad luck. In the past, a lot of tall buildings didn’t even have a 13th floor. However, there aren’t really any other numbers that are special in this way in the West. There are superstitions (迷信) about some numbers in China as well. For example, the number “4” is said to be unlucky because it sounds like the Chinese word for “death”. But that’s just one small example of China’s obsession (迷恋) with numbers. When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. Because Chinese characters (文字) cannot be used for website addresses. They can only use numbers or the letters of the Roman alphabet. In pinyin, the telecom company China Unicom is called Zhongguo Liantong. If the company used their pinyin name for their website address, it would be quite long. So instead, they use their customer service hotline number —10010. com. This is easier to type and remember. In addition, the pronunciations (发音) of some numbers sound similar to other words in Chinese. This makes for some clever wordplay. For example, the numbers “5-2-0” in Chinese sound similar to the pronunciation of the Chinese phrase “I love you”. Many couples choose to get married on May 20 for this reason. It is interesting to see how Chinese people have used numbers in so many different ways. “88” for now! 1．Which number do some people in Western countries think is unlucky? A．2. B．4. C．5. D．13. 2．What surprised the writer when he came to China? A．4 is an unlucky number in China. B．China regards 13 as an unlucky number. C．Some tall buildings don’t have a 13th floor in China. D．China uses numbers in website addresses. 3．What’s the website address of the telecom company China Unicom in the passage? A．Zhongguoliantong. com. B．TCCU. com. C．10010.com. D．TelecomChina. com. 4．Why do many couples in China choose to get married on May 20? A．Because the weather is usually good on that day. B．Because it always falls on a weekend. C．Because 5, 2 and 0 are all lucky numbers in China. D．Because its Chinese pronunciation is similar to “I love you”. 5．What’s the best title of this passage? A．China loves numbers B．The special numbers in West C．Lucky number in China D．Lucky number in Western countries 【答案】1．D 2．D 3．C 4．D 5．A 【导语】本文主要介绍了中国关于数字的迷信。 1．细节理解题。根据“In Western countries, some people think the number 13 brings bad luck.”可知，在西方国家，13这个数字被认为是不吉利的，故选D。 2．细节理解题。根据“When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. ”可知，惊讶地发现许多网站的名称中都有数字而不是字母，故选D。 3．细节理解题。根据“So instead, they use their customer service hotline number —10010. com.”可知，中国联通的网站是10010.com，故选C。 4．细节理解题。根据“For example, the numbers ‘5-2-0’ in Chinese sound similar to the pronunciation of the Chinese phrase ‘I love you’.”可知，因为它的中文发音与“我爱你”相似，故选D。 5．最佳标题题。通读全文可知，本文主要介绍了中国关于数字的迷信，A选项能概括本文主题，故选A。 I used to believe that only words could catch the spirit of the human soul. There were such stories that shaped the way we saw the world. Words were everything. That belief changed. In an ordinary math class, my teacher raised a simple question: What’s 0.99 rounded (四舍五入) to a whole number? Easy. When rounded to a whole number, 0.99=1. Somehow, I thought even though 0.99 is only 0.01 away from 1, there’s still a 0.01 difference. That means even if two things are only a little different, they are still different, so doesn’t that make them completely different? My teacher answered my question by giving another equation (等式): 1=0.9, which could also be expressed as 1=0.999999...repeating itself without ever ending. There was something mysterious but fascinating about the equation. The left side was unchangeable. On the right was something endless, a number repeating itself limitless times (无限次). However, in a certain way, these two different things were connected by an equal sign. Lying in bed, I thought about how much the equation is parallel to our life. The left side of the equation shows that sometimes life itself is so unchangeable and so clear. The certain, whole number of the day when you were born and the day when you would die. But then there is that gap in between life and death. The right side means a time and space full of limitless possibilities, and endless chances into the open future. So that’s what life is. Objective but imaginative. Unchangeable but limitless. Life is an equation with two sides that balances itself out. Still, we can’t ever truly seem to put the perfect words to it. So possibly numbers can express ideas as words can. For now, let’s leave it at that: 1=0.999999...and live a life like it. 1．What is paragraph 1 mainly about? A．Words have a long history. B．Words express a lot. C．There are different kinds of words. D．There are many sounds of a word. 2．Why does the writer think the equation is mysterious but fascinating? A．Because it has an endless repetition. B．Because nobody else but the teacher knows it. C．Because it shows two different numbers can be equal. D．Because it is the hardest math question the writer has met. 3．Which of the following underlined parts has a similar meaning to “is parallel to”? A．I love my teacher. He is like a father to me. B．Our actions can make a difference and lead to a better future. C．A happy childhood has nothing to do with new developments in technology. D．I find it difficult to remember everything, but I’m gradually getting used to it. 4．What is the best title for the passage? A．The Powerful Word B．The Perfect Equation C．An Unforgettable Question D．An Excellent Teacher 【答案】1．B 2．C 3．A 4．B 【导语】本文主要讲述了作者在数学课上学了一个神秘的等式后，引发其对人生的思考和感悟。 1．段落大意题。根据“I used to believe that only words could catch the spirit of the human soul. There were such stories that shaped the way we saw the world. Words were everything.”可知，作者曾经认为只有文字能抓住人的灵魂，可以塑造人们的世界观，强调了文字的力量。B选项“文字可以表达很多”符合本段大意。故选B。 2．细节理解题。根据“There was something mysterious but fascinating about the equation. The left side was unchangeable. On the right was something endless, a number repeating itself limitless times.”可知，等式左边是一个不变的数字，而右边是一个无限循环的数字。方程式呈现了两个不同的数字可以是相等的，这让作者感到神秘且迷人。故选C。 3．词义猜测题。根据“I thought about how much the equation is parallel to our life...chances into the open future.”可知，作者觉得一边生死本身是不可改变的，一边生命又存在有无限的机会和可能性，和数学课上学习的等式呈现的内容是相似的。be parallel to“与……相似”，A选项be like“像……一样”与划线词语表意相近。故选A。 4．最佳标题题。根据“My teacher answered my question by giving another equation: 1=0.9”及全文内容可知，文章主要讲述作者在数学课上学习的等式以及引发的思考。B选项“完美的等式”符合原文。故选B。 In the last century, different natural disasters have robbed several cultural heritage (遗产) from us. On WeChat, some people say, “What a pity that we cannot see the damaged parts of the wonders anymore.” But people can see them in a new way—through a video game. In this game, the player can travel to one city after another and enter the buildings exactly like they are in reality, and see the wonders as they were before the fire. Maybe digital technology (数字技术) could help protect cultural heritage better. This idea dates back to the 1990s and the necessary technology has continued to develop since then. By scanning (扫描) the ancient buildings, building 3D models, as well as measuring everything, scientists can make a copy exactly as the real one. As computers and smart phones are popular, the digital copy has great value. First, it allows tourists to feel the cultural heritage without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes (敦煌石窟) is a good example of this as tourists can view the paintings without standing near them. Second, it can make the cultural heritage more famous by spreading information about them through the Internet. In 2000, a virtual tour of the Dunhuang Grottoes became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years. Last, it stores all the information of the cultural heritage. Even if the real ones are damaged one day, people can still know what they were like and can build a new one if wanted. Of course, however exact a model is, it is not the real one. Maybe we will have better technologies in the future, but the digital technology offers a practical way to protect cultural heritage at the moment. 1．We can see the damaged parts of those wonders ________. A．by entering the buildings B．through a video game C．by spreading information D．by creating another copy 2．Which is the correct order of digitalizing ancient buildings according to the passage? ① Build 3D models. ② Measure everything. ③ Scan the ancient buildings. ④ Make a copy exactly as the real one. A．②①④③ B．③①②④ C．①②④③ D．②③①④ 3．The writer uses the example of Dunhuang in Para. 3 and 4 to ________. A．show the writer is really interested in travelling to Dunhuang B．prove people can build a new one if the real ones are damaged C．show Dunhuang Grottoes are disappearing because of the disaster D．prove computers and phones makes digital copies more valuable 4．What is the writer’s attitude (态度) towards the digital technology? A．Positive. B．Negative. C．Disappointed D．Uncertain. 5．What is the best title of the passage? A．The cultural heritage. B．The damaged parts. C．The digital technology. D．The Dunhuang Grottoes. 【答案】1．B 2．B 3．D 4．A 5．C 【导语】本文主要介绍了数字技术在文化遗产保护方面的作用。 1．细节理解题。根据第一段中“But people can see them in a new way—through a video game.”可知人们可以通过一款视频游戏看到被破坏的部分。故选B。 2．细节理解题。根据第二段最后一句“By scanning (扫描) the ancient buildings, building 3D models, as well as measuring everything, scientists can make a copy exactly as the real one.”可知其顺序：扫描古建筑；建立3D模型；测量一切；制作复制品。故选B。 3．推理判断题。根据第三段内容，尤其是第一句“As computers and smart phones are popular, the digital copy has great value.”可知随着电脑和智能手机的普及，数字拷贝具有巨大的价值，接下来以敦煌石窟为例进行说明。故选D。 4．推理判断题。结合全文语境，尤其是最后一句“Maybe we will have better technologies in the future, but the digital technology offers a practical way to protect cultural heritage at the moment.”可知也许在未来会有更好的技术，但目前数字技术为保护文化遗产提供了一种实用的方法，可推断出作者对这种技术是很自信的。故选A。 5．最佳标题题。结合全文语境，尤其是第二段第一句“Maybe digital technology (数字技术) could help protect cultural heritage better.”可知本文主要介绍了数字技术在文化遗产保护方面的作用，根据选项可知“数字技术”可以作为本文的标题。故选C。 Beep!

Do you use ten different words to do it? Can you do it in English, or do you have to use your first language? Do you count on your fingers? Many people think that numbers and math are the same all over the world. But scientists have discovered that it is not true. People in different parts of the world use different ways to count on their fingers. In the United States, people begin counting with their first finger. They then extend the rest of their fingers and finally the thumb to count to five. Then they repeat this with the other hand to get to ten. In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand. Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. Some languages have only a few words for numbers, and others have no words for numbers. For example, the aboriginal people in Australia don’t have hand movements to stand for numbers. They don’t even have words for numbers. However, they are still able to understand different ideas about numbers. Similarly, people of the Piraha tribe in northwestern Brazil don’t have words for numbers such as “one” or “three”. They are not able to say “five trees” or “ten trees” but can say “some trees”, “more trees” or “many trees”. Professor Edward Gibson from the Massachusetts Institute of Technology said that most people believe that everyone knows how to count, “But here is a group that does not count. They could learn, but it’s not useful in their culture, so they’ve never picked it up.” 1．Why does the writer list the four questions at the beginning of the passage? A．To make a survey. B．To interest the readers. C．To give examples. D．To interview the readers. 2．According to Paragraph 2, what is the difference between the US and China in finger counting? A．People from China use finger positions to do counting. B．People from the US usually begin counting with their thumb. C．People from China count much faster than people from the US. D．People from the US use only one hand to count from one to ten. 3．People of the Piraha tribe are from ________. A．the US B．Brazil C．Australia D．Asia 4．Which of the following is TRUE about aboriginal Australians? A．There are ideas of numbers in their life. B．There is no “some trees” in their language. C．They have only a few words for numbers. D．They have hand movements for numbers. 5．What’s the main idea of the passage? A．Chinese people are good at counting. B．Counting quickly on fingers is not easy. C．Counting is difficult to learn in some tribes. D．People don’t need numbers in some cultures. 【答案】1．B 2．A 3．B 4．A 5．D 【导语】本文主要介绍了不同的国家关于数字的文化是不尽相同的，告诉我们在某些文化中，人们不需要数字。 1．推理判断题。根据“Many people think that numbers and math are the same all over the world. But scientists have discovered that it is not true”可知，许多人认为数字和数学在世界各地都是一样的。但是科学家们发现事实并非如此。作者通过使用四个问题来吸引读者的兴趣。故选B。 2．细节理解题。根据“In China, people count by using different finger positions.”可知，在中国，人们用不同的手指位置来计数。故选A。 3．细节理解题。根据“ Similarly, people of the Piraha tribe in northwestern Brazil don’t have words for numbers such as ‘one’ or ‘three’”可知，皮拉哈部落的人来自巴西，故选B。 4．细节理解题。根据“However, they are still able to understand different ideas about numbers.”可知，然而，他们仍然能够理解关于数字的不同想法。故选A。 5．主旨大意题。通读全文可知，本文主要介绍了不同的国家关于数字的文化是不尽相同的，告诉我们在某些文化中，人们不需要数字。故选D。 Many of us may have experienced the pleasant moment of seeing recommended (推荐) songs after we listen to some songs on a music app. When we open shopping websites, we often see things we want to buy on the home page. The businessman can decide which is the best place to build a new entrance in a big supermarket in the city center. If you want to take a taxi on a taxi app, it can even guess where you want to go before you tell it! Aren’t these things amazing? This is based on data (数据). Data is no longer only about numbers, but information from almost every side of our lives: our shopping habits, interests or what we eat. All of this is called “big data”. In December 2017, President Xi Jinping called for China to speed up its big data strategy (战略) to better serve social development. As a result, people’s lives can be improved as well. He also asked for greater use of big data in areas like education, and transportation. We have seen big data being used more often in China in the past few years. The role it plays in travel is just one example. Many travelers today like to share their experiences with others on the Internet. All the data that travelers share online is helping the tourism industry get a lot of information. After the data is analyzed (分析), these tour sights can know about travelers’ needs better. In this way, services will be improved, which is helpful to the development of the whole industry. As a result, travelers can expect better tours in the future. Moreover, big data is also an important growth tool for trade. With growth rate of 30 percent every year, sales of big data industry in China will reach one trillion (万亿) yuan yearly by 2020. Having so many good influences, big data is sure to be seen more and more in China. 1．According to Paragraph 1, big data can help people ________.

The computer program looks for different kinds of answers or patterns（模式） in the data. Big data can have different kinds of information from many sources, such as information that comes from schools, social media（媒体）sites, companies, and governments. One set of data can have people’s names and addresses. Another set can have what they like, where they go, and how much time they spend on the computer. Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra（额外的）help in class. The teachers can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream. Big data can be used for good reasons. Some hospitals use big data to predict（预测）if a baby who was born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong. How can big data be used for good and bad things? It is because the computer programs used to look at big data and understand it are written by people. People think in a certain way. Because they think a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people. 1．What does the underlined word “sources” in Paragraph 1 mean? A．Schools that you come from. B．Places that you get things from. C．Answers that you try to look for. D．Companies that you care about. 2．How can schools help students with big data according to Paragraph 2? A．By recording how they get to school. B．By checking if they were born early. C．By finding out who needs extra help. D．By asking what ice cream they buy. 3．Which of the following is TRUE about big data according to the passage? A．It may bring some problems. B．The government can control it very well. C．It is used by hospitals the most. D．People should send photos online to improve it. 4．Which of the following best shows the structure of the passage? A． B． C． D． 5．What is the writer’s purpose according to the passage?

But how about making one disappear? A new report said a long time of climate(气候) change could do that. It also said Tuvalu would be the first country to be completely lost because of climate change. Tuvalu, a Pacific island country with many small islands, is near Australia, lying in the South Hemisphere(南半球) and there are only 12,000 people in this country. Now, 40 percent of the area in its capital is underwater. ▲ . They don’t want to lose their country, so they plan to build a new one in the metaverse(元宇宙). It is a digital(数字化) country that only shows online. No matter where Tuvalu people live in the real world, they will still have their nationality(国籍) and “live” in its online country. For example, if a Tuvaluan misses the beautiful butterflies and the soft wind in their hometown, he can enter their digital country online and enjoy them. This news made people in Tuvalu excited. But Li Zuxi, a director of the metaverse lab, said, “Though the digital country belongs to Tuvalu, it’s built on a metaverse platform(平台). Now, the metaverse is not perfect, which may bring some problems. He gave us an example. If someone from other countries enters the space of the digital country, how can the system tell if the person truly belongs to that country. In such situations, the safety of this digital country can’t be made sure of.” However, many island countries disagree with Li Zuxi. They say that building a digital country may be new, but this is the only way for people in those island countries to be connected. Why not have a try? Actually, whether people will build it or not, saving the real world and creating a better living environment should be paid the most attention to. 1．From the picture, Tuvalu lies in the place of ________. A．L1 B．L2 C．L3 D．L4 2．Which sentence can be put in the ▲ ? A．The government of Tuvalu hasn’t done enough to save the country B．Whether the country will disappear depends on how Tuvalu people protect the environment C．People from all over the world are trying to save Tuvalu from disappearing D．Facing the disappearing of their country, all Tuvalu people are so sad 3．From Li Zuxi’s words, we can infer that ________. A．the digital country in the metaverse is perfect enough now B．there is a long way to go if people want to build a country in the metaverse C．people can’t make sure of the safety of the digital country D．all the island countries are building a digital country in the metaverse 4．The structure of this passage is ________.

The Library Cave in Mogao Grottoes was discovered in 1900, with more than 60,000 cultural relics dating from the 4th century to the 11th century unearthed. It was one of the most important archaeological discoveries in the 20th century. On the platform, visitors can role-play and “time travel” to ancient dynasties and talk with eight historical figures. The public can enter the platform through the Digital Dunhuang website and its WeChat mini program. In the digital age, the model of “culture+technology” has been adopted to promote (促进) the development of Chinese culture. The digitalization rate of China’s precious cultural relics has been more than 70 percent, according to the 2022 China Digital Collection Industry Research Report released by iResearch. The Ministry of Culture and Tourism has also encouraged the development and transformation (转型) of cultural intellectual property by digital means. CCTV (China Central Television) has created a series of digital collections with different Dunhuang themes, such as the Dunhuang divine deer Youyou. It was created based on the image of the nine-colored deer from Dunhuang murals. The public can see the divine deer on CCTV’s own digital platform. Digital collections cater to (迎合) the consumption habits of young people. They not only protect the intellectual property of the collections but also bring the public closer to China’s “excellent traditional culture”, noted Dunhuang Art Institute. Su Bomin, director of the Dunhuang Academy, told Xinhua that more efforts will be made to explore new forms for showing cultural relics and offer the public more immersive cultural experiences to develop Dunhuang culture. 1．On the Mogao Grottoes’ Library Cave, visitors can ________. A．play role-playing games set in ancient times B．play video games named historical characters C．design digital caves showing historical culture D．talk to the designer of the digital Library Cave 2．What is the purpose of developing digital platforms for cultural institutions?

They not only protect the intellectual property of the collections but also bring the public closer to China’s ‘excellent traditional culture’”可知，中央电视台制作了一系列不同敦煌主题的数字合集，比如敦煌神鹿呦呦，数字合集迎合年轻人的消费习惯，它们不仅保护了藏品的知识产权，还拉近了公众与中国“优秀传统文化”的距离。故选D。 4．最佳标题题。通读全文可知，本文围绕“‘文化+科技’的模式推动中国文化的发展”来介绍，也就是让人们在线体验历史，所以B选项“在线体验历史”符合本文标题，故选B。 From November 1st to December 10th in 2020, China started its seventh national population census(普查). 7 million census takers have asked each family about their name, gender(性别), age, education, job and so on. This census is different from the ones in the past. For the first time, citizens were encouraged to use smartphones and other digital tools to record their information. China has a national population census every 10 years. The first one was done in 1953. At that time, there were about 600 million people in China. But China’s population has boomed. It was about 1.37 billion in 2010. For the 2020’s national population census, all people of China were included in the census. But Chinese citizens who had settled(定居) abroad and foreigners who were staying in China on either business or tourist visas(旅游签证) were not counted. “The census is very important for every citizen,” said Ning Jizhe. “It will help improve infrastructure(基础建设) and public services. For example, if census results show that there are many children living in an area, the government will know that it should build more schools there.” Scientists can also learn more about population growth from the census. In some years, the population grows faster than in others. Even in the same year, population growth is different in different places. Scientists can use the information to find out what causes growth in certain years and places. 1．Why was the 2020’s national population census different from others? A．China had the larger population in 2020 than in other years. B．The 2020’s national population census included people’s jobs and education. C．People could use digital tools to record their information in 2020. D．The 2020’s national population census took the shortest time. 2．The first national population census in China was done ________. A．in 1953 B．in 1964 C．in 2000 D．in 2010 3．What does the underlined word “boomed” in Paragraph 2 probably mean in Chinese? A．下降 B．包括 C．测量 D．增长 4．________ was included in the 2020’s national population census. A．Chinese people who are traveling abroad B．Chinese people who have settled in other countries C．Foreigners staying in China with business visas D．Foreigners staying in China for holidays 5．Why is the national population census important? A．Scientists can compare(比较) the population of China with the population of the world B．The government will build more schools. C．It is helpful to improve infrastructure and public services. D．The population in China grows faster than in other countries. 【答案】1．C 2．A 3．D 4．A 5．C 【导语】本文主要介绍了中国的第7次人口普查，并讲述了人口普查的历史以及人口普查的范围和意义。 1．细节理解题。根据“This census is different from the ones in the past. For the first time, citizens were encouraged to use smartphones and other digital tools to record their information.”可知，2020年人口普查不同于以前人口普查的原因是使用了智能手机和其他数据工具记录普查信息。故选C。 2．细节理解题。根据“China has a national population census every 10 years. The first one was done in 1953.”可知，第一次人口普查是在1953年。故选A。 3．词句猜测题。根据“The first one was done in 1953. At that time, there were about 600 million people in China. But China’s population has boomed. It was about 1.37 billion in 2010.”可知，在1953年人口普查数据是大约600万人，到了2010年大约是13.7亿人，因此人口是增长了，可推知boom表示“增长”。故选D。 4．细节理解题。根据“For the 2020’s national population census, all people of China were included in the census. But Chinese citizens who had settled(定居) abroad and foreigners who were staying in China on either business or tourist visas(旅游签证) were not counted.”可知，2020年人口普查没有包含中国居民定居在国外的、持商务签证或旅游签证在中国停留的外国人，因此排除BCD选项。故选A。 5．细节理解题。根据“It will help improve infrastructure(基础建设) and public services. ”可知，通过人口普查可以帮助改善基础建设和公共服务。故选C。 How many digits of pi (圆周率位数) can you remember? Just 3.1415926? Well, this may not be good enough for scientists. Swiss researchers said they broke a new record. Using a supercomputer, they counted pi to 62.8 trillion (万亿) digits. The team, at University of Applied Sciences in Graubunden, Switzerland, took 108 days and nine hours to do this! It was “3.5 times as fast as the former world record in 2020”, which reached 50 trillion digits, according to the university. Researchers are waiting for the Guinness Book of Records to certify (认证) their efforts. Since it was first discovered and understood 4,000 years ago, humans have been trying to count pi as exactly as possible. Zu Chongzhi (429-500), a Chinese mathematician (数学家) , counted pi between 3.1415926 and 3.1415927. Nobody surpassed (超过) his results for about 1,000 years — until Al-Kashi, an Iranian (伊朗的) mathematician, counted it to 16 decimal places (小数位). Why do we need to know an exact value (数值) of pi? “It’s used everywhere, from the general relativity (广义相对论) of Einstein to your GPS to all kinds of engineering problems,” Jan de Gier, a math professor at the University of Melbourne, Australia, told The Guardian. It’s true that pi pops up everywhere. But is it too much to count it to 62.8 trillion digits? “I can’t imagine any real-life use where you would need any more than 15 decimal places,” said David Harvey from the University of New South Wales, Australia. However, De Gier compares this to the Olympic Games: “World records are not useful by themselves, but they set a benchmark (基准) and they teach us about what we can achieve.” “It’s a big challenge for computers,” Harvey agreed. “It’s really a difficult thing to do and it needs lots of math and computer science.” 1．What part of this story is news? A．An exact value of pi is used everywhere. B．The value of pi was counted to a further number. C．The former value of pi was proven to be incorrect. D．A supercomputer was developed in Switzerland. 2．The former Guinness record of the value of pi reached ________. A．7 decimal places B．16 decimal places C．50 trillion digits D．62.8 trillion digits 3．Paragraph 4 is mainly about ________. A．why we work on the value of pi B．how to find the value of pi C．the person who discovered pi D．the history of pi studies 4．Harvey agrees that ________. A．we only use pi in scientific studies B．pi is used everywhere in our lives C．we need a more exact value of pi D．it’s worthless to work on the value of pi 5．In De Gier’s opinion, to set a world record is ________. A．simple B．useless C．impossible D．meaningful 【答案】1．B 2．C 3．D 4．B 5．D 【导语】本文主要介绍了圆周率的位数被计算到了62.8万亿位，解释了需要知道圆周率确切数值的原因。 1．细节理解题。根据“Swiss researchers said they broke a new record. Using a supercomputer, they counted pi to 62.8 trillion digits.”可知圆周率的值被计算到一个更精确的数字，这是新闻。故选B。 2．细节理解题。根据“It was ‘3.5 times as fast as the former world record in 2020’, which reached 50 trillion digits, according to the university.”可知圆周率的前吉尼斯纪录达到了50万亿位。故选C。 3．段落大意题。通读第四段内容可知第四段主要讲圆周率的研究历史。故选D。 4．观点态度题。根据“It’s true that pi pops up everywhere. But is it too much to count it to 62.8 trillion digits? ‘I can’t imagine any real-life use where you would need any more than 15 decimal places,’ said David Harvey from the University of New South Wales, Australia.”可知Harvey不否认圆周率在生活中的应用无处不在，但他认为没必要精确到超过15位数。故选B。 5．推理判断题。根据“World records are not useful by themselves, but they set a benchmark and they teach us about what we can achieve.”可知De Gier认为世界纪录为我们树立了一个标杆，让我们知道我们可以取得什么成就，由此推出他认为创造世界纪录是有意义的。故选D。 How did the Maya count in ancient times? How many bags of corn did they have? How many did they sell? Did all the crops arrive at the city market? To answer these important daily questions, they used some numbers like this: The Maya was good at math. They counted in groups of 20, not 10. They wrote numbers in columns going up. The bottom row was the “ls” column, the next row up was 20s, then 400s, and so on. For numbers, they used a dot () for 1, a line for 5, and a shell () shape to show zero. Numbers 1 to 19 were written with a combination of lines and dots. Can you read the number in the following picture? It’s the number 1209(three 400s + no 20s + nine 1s). The Maya also kept three different calendars. The first divided the year into 18 months of 20 days each, plus a short month of 5 days. The short month was believed to be unlucky, a time when spirits walked. The second calendar repeated every 260 days. This was used to plan religious activities. When talking about events long ago, they used a calendar called “the long count.” This had a span of about 5,136 years. Year 1 on this calendar was 3114 BCE on our calendar. Each city and village had a calendar keeper, who was in charge of saying when to celebrate holidays and when to expect rain or plant crops. But farmers could probably also tell the time of the year from the sun and stars. 1．The Maya created their way of counting mainly to ________. A．celebrate local holidays B．plan religious activities C．keep different calendars D．solve everyday problems 2．According to Maya math, the number in Picture ________ is equal to “414”. A． B． C． D． 3．Which of the following about Maya calendars is TRUE? A．Three kinds of calendars were used for different purposes. B．The first calendar was usually used to plan religious activities. C．“The long count” calendar had a history of about 3,114 years. D．The short month in the first calendar was thought to bring good luck. 4．What’s the main idea of the passage? A．The development of numbers and calendars in Maya. B．The introduction of the Maya numbers and calendars. C．The situation of Maya numbers and calendars nowadays. D．The difference between numbers in Maya and other places. 【答案】1．D 2．D 3．A 4．B 【导语】本文主要介绍了古代玛雅人的记数方法和计算日历的方法。 1．细节理解题。根据“To answer these important daily questions, they used some numbers like this”可知，是为了解决日常重要的问题，故选D。 2．推理判断题。根据“The bottom row was the “ls” column, the next row up was 20s, then 400s, and so on. …Numbers 1 to 19 were written with a combination of lines and dots”可知，414的表达方式是 14个ls，20s放“零”的标志，400s放“1”的标志，故选D。 3．推理判断题。根据“The Maya also kept three different calendars. The first divided the year into 18 months of 20 days each”“The second calendar repeated every 260 days…”和“When talking about events long ago, they used a calendar called “the long count”…”可知，这三种不同的日历的用途都是有着不同的目的，A表述正确，故选A。 4．主旨大意题。通读全文可知，本文主要介绍了古代玛雅人的记数方法和计算日历的方法，故选B。 2 同步新教材，周周有练习，月月有重点！ 7 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $$
