Many people believe that some numbers bring good luck while others bring bad luck. For example, in China, the number 8 is considered very 11 because it sounds like the word for “wealth” in Chinese. Many people choose this number for their phone numbers or car license plates. On the other hand, the number 4 is often 12 because it sounds like the word for “death”. In some buildings, you may not find a fourth floor. 13 skip the fourth floor and go straight from the third to the fifth! This is called “tetraphobia”, which means the fear of the number four. In Western countries, the number 13 is often seen as unlucky. Some people 14 to have a party with 13 guests. Also, many tall buildings do not have a 13th floor. However, not everyone 15 these beliefs. Some people think they are just silly superstitions（迷信）. Interestingly, the idea of lucky numbers can also 16 people’s decisions. For example, when buying a house, some people might 17 a house with a number they like. This shows how numbers can have a strong 18 on our choices. Whether you believe in lucky numbers or not, they are a fun part of our culture. It is always interesting to learn about the different 19 numbers carry around the world. Next time you see a number, think about what it might 20 to someone else! 11. A. common  B. lucky  C. strange  D. special 12. A. liked  B. enjoyed  C. avoided  D. welcomed 13.

Take a look at a sunflower. Its seeds are arranged in two sets of spirals（螺旋）. If you count them carefully, you will often find 55 spirals in one direction and 89 in the other. These are not random numbers. They belong to the famous Fibonacci sequence. The Fibonacci sequence starts with 0 and 1. Each number after that is the sum of the two previous ones. For example, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89... This sequence appears in many parts of nature. Pine cones, pineapples, and even the branches of trees all show these numbers. Many flowers have a Fibonacci number of petals（花瓣）. For instance, lilies have three petals, and daisies often have 34 or 55 petals. Why does nature love these numbers? Scientists believe that this pattern helps plants grow in the most efficient way. By arranging leaves and seeds in this pattern, plants ensure each one receives maximum sunlight and growing space. This is called nature’s secret code. Learning about the Fibonacci sequence can make us see the world differently. Next time you take a walk in the park, look closely at the plants around you. You might discover these amazing number patterns yourself! 21. What is the main topic of this passage? A. How to plant sunflowers. B. Number patterns in nature. C. The life cycle of pine cones. D. Famous mathematicians in history. 22. According to the Fibonacci sequence, what number comes after 34? A. 45 B. 55 C. 89 D. 144 23. Why do plants follow the Fibonacci pattern according to scientists? A. To produce more flowers. B. To grow taller and stronger. C. To get the most sunlight and space. D. To protect themselves from insects. 24. What can we infer from the last paragraph? A. The writer encourages readers to observe nature. B. The writer thinks Fibonacci numbers are boring. C. The writer believes plants can do maths. D. The writer wants to become a biologist. (B) Do you know that the way people use numbers can tell us a lot about their culture? Different countries have developed different number systems throughout history. Today, most of the world uses Arabic numerals, but that was not always the case. The ancient Egyptians used a system based on pictures. They drew symbols for different numbers. For example, a single line represented the number one, and a symbol shaped like a heel bone stood for ten. This system worked well for counting things like crops and animals. However, it was difficult to use for large numbers or complex calculations. The Mayans of Central America developed an advanced number system over 2,000 years ago. They used only three symbols. A dot meant “one”, a bar stood for “five”, and a shell shape represented “zero”. It was one of the earliest number systems to incorporate（纳入）the concept of zero, a groundbreaking invention in mathematics. Today, numbers in digital form are used everywhere, from watches to computers. These numbers have changed the way we live and work. The history of numbers shows us how human thinking has developed over time. It reminds us that even simple things like numbers have a rich and interesting past. 25. What number system do most people use today? A. Egyptian numerals. B. Mayan numerals. C. Roman numerals. D. Arabic numerals. 26. What problem did the ancient Egyptian number system have? A. It used too many symbols. B. It was hard to use for large numbers. C. It did not include the number zero. D. It could only count animals. 27. Why was the Mayan number system special? A. It used pictures to show numbers. B. It was invented in Europe. C. It was based on the number ten. D. It was the first to use the number zero. 28. What is the writer’s purpose in writing this passage? A. To teach readers how to count in different ways. B. To explain why Arabic numerals are the best. C. To show the development of number systems. D. To compare ancient Egypt and Central America. (C) Numbers are also important in the world of music. Musicians use numbers to read and write music, keep the rhythm, and tune their instruments. Without numbers, it would be very difficult to play together in a band or orchestra. One of the most common applications of numbers in music is timekeeping. Musicians count beats to keep the same speed. For example, in a 4/4 time signature（拍号）, there are four beats in each measure（小节）. The first beat is usually the strongest, and the third beat is also a bit stronger. This helps musicians feel the rhythm and play together smoothly. Another way numbers help musicians is through intervals（音程）. An interval is the distance between two musical notes. For example, a “fifth” means the two notes are five scale degrees（音级）apart. Musicians use these numbers to build chords（和弦）and create harmonies（和声）. There are also numbers written above the musical notes. These tell the musician which finger to use when playing an instrument. For example, a “1” might mean the thumb, and a “5” might mean the little finger. This is especially important for piano and string players. So next time you listen to your favourite song, remember that numbers are working behind the scenes to make it sound so good! 29. What is the main idea of this passage? A. How to play the piano. B. The history of musical notes. C. How numbers are used in music. D. The importance of rhythm in songs. 30. What does a 4/4 time signature mean? A. There are four notes in each measure. B. There are four measures in the song. C. There are four musicians in the band. D. There are four beats in each measure. 31. What is an interval in music? A. A type of musical instrument. B. A break between two songs. C. The distance between two notes. D. The speed of a piece of music. 32. Why do numbers appear above musical notes? A. To show the pitch of the note. B. To tell the musician which finger to use. C. To indicate how loud to play. D. To mark the end of the song. (D) Have you ever thought about how numbers help us protect the environment? Scientists use numbers every day to study climate change, track endangered animals, and measure pollution. Without numbers, we would not know how serious these problems are. One important use of numbers is in counting animal populations. By counting the number of a certain species in the wild, scientists can tell if that animal is in danger. For example, the number of giant pandas in China has increased from about 1,100 in the 1980s to over 1,800 today. This information helps the government make better decisions to protect them. Numbers are also used to measure air quality. The Air Quality Index, or AQI, is a number that tells us how clean or polluted the air is. When the AQI is high, people with breathing problems should stay indoors. This helps keep people healthy. Scientists also use numbers to track global temperatures. By comparing temperature records from different years, they can see how fast the Earth is warming. This information is very important for making plans to slow down climate change. As we can see, numbers are powerful tools for protecting our planet. They give us clear facts that help us take action. The more we understand these numbers, the better we can care for our world. 33. How do scientists use numbers to help endangered animals? A. By counting their population. B. By testing their DNA. C. By feeding them better food. D. By moving them to zoos. 34. What does the Air Quality Index (AQI) tell us? A. The number of cars on the road. B. The speed of the wind. C. How clean or polluted the air is. D. The temperature of the air. 35. According to the passage, why are numbers important in environmental protection? A. They help us save money. B. They provide facts for taking action. C. They make us more interested in science. D. They tell us which animals are friendly. 第二节 阅读填空（共 5 小题；每小题 1 分，满分 5 分） 阅读短文及文后选项，选出可以填入空白处的最佳答案。 Numbers are widely used in the business world. Managers use them to make almost every important decision. For example, they check sales figures every month to see which products are popular. 36 This information helps them decide how many items to produce next season. Numbers also play a key role in employee performance. Many companies set clear goals for their workers. A salesperson may need to reach a certain number of customers each week. 37 When workers meet their goals, they may receive bonuses（奖金）or promotions（晋升）. Customer satisfaction is another area where numbers matter. After each purchase, companies often ask customers to give a score from one to ten. 38 A low score tells them that something needs to be improved. Budgeting is also impossible without numbers. All departments in a company must plan how much money they will spend each year.  39 If they spend too much, the company may lose money. If they spend too little, they might miss important opportunities. In short, numbers are the language of business. 40 Without them, companies would not know if they are succeeding or failing. That is why learning to work with numbers is so important for future business leaders. 选项： A. The scores show companies how well they are serving their customers. B. If the numbers go down, they know it is time to change their strategy. C. They need to explain the plan to their team members clearly. D. They help managers see the true situation and make wise choices. E. These targets help workers understand what is expected of them. 三、项目情境（读写综合）（共两节；满分 20 分） 第一节 项目情境（共 5 小题；每小题 2 分，满分 10 分） 阅读以下关于学校“数字与生活”主题实践活动的介绍，请根据同学们的兴趣匹配对应的活动内容，并将活动内容所对应的 A、B、C、D、E、F 选项填在相应位置上。选项中有一项为多余选项。 A. You will work in small teams to study how people in your neighbourhood use their time each day.

Last term, our class chose to help at a local food bank. Our teacher divided us into five groups. Each group was responsible for collecting and sorting food donations. My group recorded the number of cans, bags of rice, and boxes of milk we received every day. At the beginning of the project, we collected about 50 items per day. Our teacher encouraged us to do better. She asked us to reach a goal of 100 items daily. We put up posters around the school and gave short speeches during morning assembly. Within two weeks, the number of donations doubled. By the end of the project, we had collected over 1,500 items in total. The food bank manager was very grateful. She told us that our work helped feed nearly 200 families in our community. She also showed us a chart illustrating the monthly food needs of the people the bank served. The numbers on the chart surprised us. Demand was much higher in some months than in others, especially during the winter and summer holidays. This experience taught me the value of numbers in community work. They are not just cold data. They show us where help is needed most and prove that our small actions can make a real difference. I realised that when we work together towards a clear target, the results can be seen clearly through simple counting. 46. What did each group record during the community project? 47. How many items did the class collect per day at first? 48. What goal did the teacher set for the students? 49. How did the class increase the number of donations? 50. According to the food bank manager, which months had higher demand? 四、写作（共三节；满分 30 分） 第一节 语篇填词（共 5 小题；每小题 1 分，满分 5 分） 根据下列语篇以及所给单词的首字母写出所缺单词。（每空只写一词） Meteorologists rely heavily on numbers in their daily work. They collect data from weather stations nationwide and tally sunny, rainy and windy days each month. This information helps them understand climate patterns better. To make accurate forecasts, they also compare the predictions from their computer models with the actual weather conditions. If the numbers do not match, they know their models need improvement. On weather maps, different s (51) are used. For example, a blue line r (52) a cold front（冷锋）, while a red line stands for a warm front. These visual tools make the data easier to read. Weather reports are broadcast on television according to a fixed s (53) every day. People depend on these reports to plan their outdoor a (54). The whole weather prediction s (55) would not work without numbers. Every metric（指标）, from temperature to wind speed, is recorded numerically(以数字形式). That is why meteorologists(气象学家) say that numbers are the language of the sky. 第二节 语法填空（共 5 小题；每小题 1 分，满分 5 分） 阅读下面短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。 Long ago, people used different methods to record numbers. One common way was to use tally marks. They drew lines on bones or wood, and each line stood for one object. However, this method was impractical（不切实际的）for counting large quantities. (56) (count) a thousand sheep, they had to draw a thousand lines! This problem led to the invention of more advanced systems. The ancient Chinese developed a clever system using counting rods（算筹）. They placed small sticks in different positions to show numbers. The system was so effective (57) it remained in use for centuries. Merchants and officials depended on it for their daily work. Today, we use Arabic numerals, which are much easier to write. But have you ever thought about (58) important these numbers are? Without them, we could not do maths or keep records. Many scientists believe that numbers are one of the greatest (59) (invention) in human history. They help us describe the world clearly. I became interested in the history of numbers after my maths teacher told us some amazing stories last term. Now I enjoy reading about ancient counting methods in my free time. Everyone can learn (60) (anything) valuable from these old systems. 第三节 书面表达（共 1 题，满分 20 分） 生活中，数字除了帮助我们解决实际问题，还能记录我们成长的点滴。校刊英文版正在征集以“The Number That Means the Most to Me”为主题的短文。请你写一篇短文投稿，分享一个对你来说最有意义的数字。 提示： 1. 这个数字是什么。 2. 为什么这个数字对你有特殊意义。 3. 这个数字给你带来了怎样的影响或启示。 要求： 1. 短文词数在 80 词以上。 2. 行文条理清晰，语句通顺连贯，语法规范无误。 3. 书写工整，卷面整洁，文中不得出现真实的人名、班级及学校名称。 The Number That Means the Most to Me 参考答案 一、语言知识及运用 第一节 语法选择 1.

It was my score on my first English exam in middle school. I still remember that day clearly. I studied hard but still only scored 62. I felt so disappointed that I almost gave up. However, my teacher told me that this number was not a failure but a starting point. She helped me work out a step-by-step study plan to improve my English. I started reading English aloud every morning and keeping a daily vocabulary log. Three months later, I got 85 on the next exam. Now my English is among the best in my class. The number 62 reminds me that failure is not the end. It is just the beginning if I keep trying. This number taught me never to give up easily. 1 1 学科网（北京）股份有限公司 $
