2025-2026学年沪教版（2024）八年级英语上册满分冲刺专练 Unit 2 Amazing numbers 阅读理解专练 （1） Many Chinese idioms contain numbers, such as caigao badou (才高八斗) and banjin baliang (半斤八两). Why do they have something to do with numbers? A talented person The idiom caigao badou is used to describe a talented person. It is based on a story about Cao Zhi (192-232), the younger son of Cao Cao (155-220), a warlord (诸侯) who lived during the Three Kingdoms period. Cao Zhi was one of the best poets of his time. Besides his poetry, his fu (赋) was also excellent. His works, such as Luoshen Fu (《洛神赋》), are full of beautiful descriptions. Xie Lingyun (385-433) was a famous poet who lived during the Eastern Jin Dynasty. He was quite proud of his own writing, but also admired Cao Zhi’s talent. He once said to others: “Heaven only gave the world one dan of talent, and Cao Zhi alone had eight dou. I deserve (值得) one dou, and all the other poets should share the last one dou.” The dan used was an ancient Chinese measurement for grain. One dan is equal to 10 dou. The idiom can be translated into “eight bushels of talent” in English. Standing tall In China, people often say “standing like a 7-chi-tall man”（堂堂七尺男儿). How tall exactly is a 7-chi-tall man? When people say qichi naner (七尺男儿), they’re usually referring to a man who is tall and strong. However, it’s not easy to tell exactly how long seven chi is. As a traditional Chinese unit of length, the measurement of chi has changed often over time. In earlier times, such as the Shang Dynasty (16th century-11th century BC), one chi was about 16 cm. So seven chi would be equal to about 110 cm. A 7-chi-tall man at the time would be a little person. When it came to the Three Kingdoms period (220-280), one chi became longer and reached 24.2 cm. So seven chi would be about 170 cm, an average height today. In the following dynasties, chi kept growing longer. It became about 30 cm in the Tang Dynasty (618-907) and finally 35.5 cm in the Qing Dynasty (1644-1911). It means that a 7-chi-tall man would be 248.5 cm. That would be a real giant! Same difference The idiom banjin baliang (半斤八两) means “same difference”. One jin and eight liang used to be the same. Chinese people measured weight differently in the past. At that time, one jin (500 grams) was made up of 16 liang. So half of one jin was eight liang. People used a steelyard balance (杆秤) to weigh things. It had 16 gradations (秤星) on its arm. Each gradation stands for one star in the sky. The 16 gradations stand for 16 stars – the Big Dipper (北斗七星), Sagittarius and the stars of fortune, prosperity and longevity (福禄寿星). It was said that if you cheated someone while trading, you would lose the blessing (庇佑) of these stars. This helped to keep people honest while trading. After 1949, China started to do more international trade. To make things easier, we changed 16 liang for one jin into 10 liang for one jin. 1．From the text, “caigaobadou” first mainly described a talented person, his name was ________.

But it’s very “thirsty”, said a new study from Harvard University. ChatGPT has “homes” around the world in data centres (数据中心). When it works, the computers in the data centres get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away the pipes. When you ask ChatGPT 50 questions, it “drinks” 500 millilitres (ml) of water. Scientists used about 700,000 litres of water to build ChatGPT. The water use is very big. People can make 370 cars with the water. ChatGPT is just one of the AI tools around the world. You need data centres to do everything on the internet. There are more than 8,000 data centres around the world. The number is still growing. AI uses a lot of water to “grow”. The world’s water may not be enough. Many people don’t have enough water to drink. But AI technology helps people. Should we rethink how we use AI? 6．Which of the following can ChatGPT do? ①Answer questions. ②Fly planes. ③Write articles. ④Tell stories.

D．We may have to “fight” with AI for water in the future. 4．What is the main idea of the article? A．ChatGPT is a good artificial intelligence tool. B．ChatGPT needs lots of water when it works. C．ChatGPT helps people do many different things. D．ChatGPT has “homes” around the world in data centres. （3） To celebrate a breakthrough (突破) by students in using AI to change silkie chicken (乌骨鸡) farming at the chicken farm in Chishui, Guizhou Province, the Tencent Cloud Artificial Intelligence Class—a programme set up by the university and Tencent—offered free “AI chicken soup” to all teachers and students at Shenzhen University on 16 January, 2024. “As the Spring Festival is on the way, the farm in Chishui sent hundreds of chickens and eggs to the university, so we decided to turn these chickens into ‘AI chicken soup’ before the holiday to give teachers and students a taste of technology,” said Chen Sirui, a student in the class. Over eight months, about a dozen students from the class have tried to dedicate themselves to developing the silkie chicken farming in Chishui. They used the computer vision technology to successfully identify (识别) and track (追踪) 250,000 silkie chickens. The result was a success of the world’s first intelligent silkie chicken farming system. Operating for more than six months, the system increased the farm’s output by 30%, keeping another 60,000 chickens. Class member Chen said, “This system sends valuable data to the chicken farmers’ mobile phones. The farmers can notice their chickens at any time. The aim is to raise the income of the farmers.” A leader of the university said, “The project enables students to face real industry challenges, deepens their understanding of technology and develops their practical skills.” 1．Why was the free soup offered to teachers and students? A．To celebrate the coming Spring Festival. B．To share the joy of the successful chicken farming by using AI technology. C．To set up a new program of silkie chicken farming. D．To increase the total production of silkie chickens. 2．What does the underlined word “dedicate” mean in Paragraph 3? A．complete B．change C．improve D．devote 3．What is the future of this technology? A．More people will work on this kind of farm. B．Farmers will use computers to raise chickens. C．More farmers will raise this kind of chicken. D．The new farming system will be more popular. 4．Which of the following isn’t the project’s advantage to the students? A．Raising their income after graduation. B．Helping them face the real industry challenges. C．Deepening their understanding of technology. D．Developing their practical skills. （4） Do you have a lucky number? Many people have a special number and they hope that it will bring them good luck. In China, people think some numbers are lucky or unlucky because those numbers sound similar to some Chinese words with good or bad meanings. For example, the word for number 8 sounds like “making lots of money” in Chinese. So, people think it is a very lucky number. Some people even spend much more money to have 8s in their phone numbers. Do you remember the Summer Olympic Games in Beijing? It opened at 8:00 p.m. on August 8, 2008 The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on the emperors’ robes (龙袍) and it’s told in many ancient Chinese stories that the dragon has nine children. The number 9 also means “long lasting”. In China, a man would send 99 or 999 roses to his lover with the wishes that the love between them will be long-lasting. What’s more, the Chinese think that the number 2 is lucky as it’s said that “all good things come in pairs”. For example, during wedding celebrations, you usually find pairs of red candles, double pillows and many other things in pairs. And people often give gifts in pairs for someone’s birthday, wedding or other celebrations. So what’s an unlucky number in China? It might be 4. Many Chinese people see 4 as an unlucky number because it sounds similar to the Chinese word “death”. Because of this, many buildings skip the fourth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as 4, 14, 24 and 34. As a result, a building with 50 floors may have only 36 floors actually. 1．What makes Chinese people believe a number is lucky or unlucky? A．The shape of the number. B．The quantity of the number. C．The history of the number. D．The sound of the number in Chinese. 2．Some people would pay much more money for ________. A．the Summer Olympic Games B．the phone numbers with 8s C．the emperors’ robes D．the wedding celebrations 3．Why would a man like to send 99 roses to his lover? A．Because he thinks that women love roses the best. B．Because the number 9 has a connection to the emperors of China. C．Because he hopes that he will be in love with the woman for a long time. D．Because he wishes that he will have lots of children with the woman in the future. 4．In Hong Kong, you may NOT find the ________ floor in some buildings. A．50th B．35th C．46th D．17th 5．What is the purpose of the passage? A．To describe numbers and ancient stories in China. B．To introduce lucky and unlucky numbers in Chinese culture. C．To help readers find their lucky and unlucky numbers. D．To compare different meanings of numbers in different countries. （5） I love studying numbers because they are full of surprises. One amazing number is 1. It is the building block of all numbers. Another interesting number is 10, which is the base of our decimal system. I also like learning about prime numbers. They are numbers greater than 1 that have no divisors other than 1 and themselves. Studying prime numbers helps me understand number patterns better. Numbers also have stories. For example, the number 2 is the only even prime number. Learning these stories makes studying numbers more fun. 1．What does the writer think of numbers?

The number π, for example, is an infinite decimal that has fascinated mathematicians for a long time. It is used in many areas of science and engineering. Another important number is zero, which was a great invention in the history of mathematics. Numbers also have cultural significance. In some cultures, certain numbers are considered lucky or unlucky. For instance, the number 7 is often seen as lucky in Western cultures.

However, there are a lot of number expressions (表达) that can help. Today, I will talk about expressions about numbers. Sometimes we can “kill two birds with one stone”. That is to say, we can complete two goals with only one effort or action. But we must remember that “two wrongs don’t make a right”. If someone does something bad to you, you should not do the same to him. When I was a young child in school, I liked learning Maths. My teacher used to “give me three cheers” when I did well in Maths, praising (赞扬) my hard work and good grades. When I was in high school, some of my friends once had trouble doing their schoolwork. In fact, they did not care if they could finish high school. But it seemed that they really got a surprise when they completed their studies and graduated from high school. They were on cloud nine. Nine times out of ten, students who do well in school often find good jobs. Some people work in an office doing the same things every day at nine-to-five jobs. However, it’s good to know happiness at work isn’t just about money. 1．What does the second paragraph mainly tell us? A．The ways to find answers. B．Two problems are difficult to solve. C．The importance of working together. D．The meanings of two expressions about numbers. 2．When we ride a bike to a park instead of driving a ear, we can save money as well as protecting the environment. Which expression can we use here? A．Put two and two together. B．Two heads are better than one. C．Kill two birds with one stone. D．Two wrongs don’t make a right. 3．What do the underlined words “on cloud nine” mean? A．Sad. B．Joyful.

B．To show different meanings of “two”. C．To introduce some interesting number expressions. D．To tell us some ways of solving some Maths problems. （8） March 14 is a great day for fans of maths. It is celebrated as Pi (π) Day, a day to celebrate the number that many people know very well. The date copies from the first three numbers of Pi (π). March is the third month and the 14th means one and four. Altogether it is 3.14. Pi (π) comes wherever there are circles (圆). Pi has been known for thousands of years and gets its name from a Greek letter, π. The Greeks are believed to be the earliest to use the letter in maths. The first Pi Day was celebrated on March 14, 1988. San Francisco’s Exploratorium Science Museum started the event. The museum marks the day with a daylong celebration. March 14 is also the birthday of the famous scientist Albert Einstein. Princeton University, where Einstein lived for many years, celebrates Pi Day as well. March 14, 2009, was celebrated as National Pi Day. And March 14, 2019 also marked the one- year anniversary (周年纪念日) of the death of Stephen Hawking. And how do people celebrate the Pi (π) Day? Maybe you can try these ideas: Eat or make different kinds of pies (for example, apple pies, cherry pies, and even pizza pies); Celebrate the day with a pie cut using the mathematical constant (常数) of Pi (π); Discuss the importance of the letter π; Watch Life of Pi in cinemas; Look for the number 3.14 in every place (such as prices and street numbers). 1．Which of the following like to celebrate the Pi Day most probably? A．Greek students. B．Movie fans. C．Maths lovers. D．Engineers. 2．When did the Pi Day start as a celebration? A．About thousands of years ago. B．On March 14,1988. C．On March 14, 2009.

D．People will talk about the achievements of Einstein. 4．Which of the following is NOT true according to the passage? A．People think the Greeks are the earliest to use the letter π in maths. B．The Greek letter a has the same pronunciation (发音) as pie. C．Stephen Hawking died in 2018. D．Einstein worked in San Francisco’s Exploratorium Science Museum before. 5．Why did the writer write this passage? A．To learn a foreign language. B．To introduce Pi (π) Day. C．To ask people to learn maths well. D．To help students work out some maths problems. （9） Do you believe in lucky numbers? The lucky number has become increasingly popular in daily life of modern society (现代社会). For example, the number eight means big money which some people like most, while the number four means death. Some people believe lucky numbers so much that they will even buy a telephone with numbers without four and others which are bad in their mind. They think that the lucky number really can come with good luck, and, at least, no evidence (证据) can show that they can not. According to what I’ve found, there is no such relationship between the numbers and luck. And, in addition (此外), man should not depend on the luck which, in their mind, the numbers give them. 1．The underlined word “increasingly” means ________. A．less B．more C．more and more D．less and less 2．According to the article, people believe the number eight can _______ them big money. A．bring B．give C．take D．promise 3．Some people even buy a telephone number to show that they believe _______. A．in lucky numbers B．that the numbers can bring good luck C．that the number four is bad D．that they hate death 4．The writer found that the numbers have _______ to do with luck. A．something B．anything C．everything D．nothing 5．People should depend on (依赖) _______. A．money B．lucky numbers C．themselves D．their parents （10） Many people hope lucky numbers will bring them good luck. In Chinese culture, some numbers are believed to be lucky or unlucky according to the Chinese characters that the number sounds similar to. For example, the number 8 sounds similar to the Chinese character for “making a fortune(发财)”. So people think it’s a lucky number. Some even spend a lot of money having the number 8 in their phone numbers or vehicle license plate numbers. The opening ceremony of the Beijing Olympics Games began at 8:08 p.m. on 8 August, 2008. The number 9 is also a lucky number because of its connection to the emperors(皇帝) of ancient China. There were nine dragons on the emperors’ robes(袍). It’s said that the dragon has nine children. The number 9 also stands for “long lasting”. That’s why a man always gives a woman 99 or 999 roses. Then what’s the unlucky number in China? It might be the number 4. Many Chinese people take 4 as an unlucky number because it sounds similar to the Chinese character for “death”. Because of this, some buildings skip the fourth floor, and people simply call it the fifth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as 4, 14, 24, 34, and all 40-49 floors. However, in many Western countries, some buildings skip the 13th floor because 13 is considered as an unlucky number. 1．In China, for which character does the number 8 sound similar to? A．Having more money. B．Keeping healthy. C．Making a fortune. D．Getting more chances. 2．Why does a man always give a woman 99 or 999 roses? A．Because he wants the woman to have a long life. B．Because he hopes they will live to 100 years old. C．Because he hopes their relation will last a long time. D．Because most women like the number 99 or 999. 3．In China,what is the fourth floor of some buildings called? A．The fifth floor. B．The fourth floor A． C．The fifth floor A． D．The fifth floor B． 4．Which is the unlucky number in Western countries according to the passage? A．4. B．24. C．7. D．13. 5．What can we learn from the text? A．Chinese people don’t build the fourth floor because it’s unlucky. B．Westerners skip the 13th floor because the number sounds similar to the word for “death”. C．Men always give women 99 roses because they want to have nine children. D．Some numbers may be considered as unlucky because of their sounds in China. 学科网（北京）股份有限公司 $ 2025-2026学年沪教版（2024）八年级英语上册满分冲刺专练 Unit 2 Amazing numbers 阅读理解专练 （1） Many Chinese idioms contain numbers, such as caigao badou (才高八斗) and banjin baliang (半斤八两). Why do they have something to do with numbers? A talented person The idiom caigao badou is used to describe a talented person. It is based on a story about Cao Zhi (192-232), the younger son of Cao Cao (155-220), a warlord (诸侯) who lived during the Three Kingdoms period. Cao Zhi was one of the best poets of his time. Besides his poetry, his fu (赋) was also excellent. His works, such as Luoshen Fu (《洛神赋》), are full of beautiful descriptions. Xie Lingyun (385-433) was a famous poet who lived during the Eastern Jin Dynasty. He was quite proud of his own writing, but also admired Cao Zhi’s talent. He once said to others: “Heaven only gave the world one dan of talent, and Cao Zhi alone had eight dou. I deserve (值得) one dou, and all the other poets should share the last one dou.” The dan used was an ancient Chinese measurement for grain. One dan is equal to 10 dou. The idiom can be translated into “eight bushels of talent” in English. Standing tall In China, people often say “standing like a 7-chi-tall man”（堂堂七尺男儿). How tall exactly is a 7-chi-tall man? When people say qichi naner (七尺男儿), they’re usually referring to a man who is tall and strong. However, it’s not easy to tell exactly how long seven chi is. As a traditional Chinese unit of length, the measurement of chi has changed often over time. In earlier times, such as the Shang Dynasty (16th century-11th century BC), one chi was about 16 cm. So seven chi would be equal to about 110 cm. A 7-chi-tall man at the time would be a little person. When it came to the Three Kingdoms period (220-280), one chi became longer and reached 24.2 cm. So seven chi would be about 170 cm, an average height today. In the following dynasties, chi kept growing longer. It became about 30 cm in the Tang Dynasty (618-907) and finally 35.5 cm in the Qing Dynasty (1644-1911). It means that a 7-chi-tall man would be 248.5 cm. That would be a real giant! Same difference The idiom banjin baliang (半斤八两) means “same difference”. One jin and eight liang used to be the same. Chinese people measured weight differently in the past. At that time, one jin (500 grams) was made up of 16 liang. So half of one jin was eight liang. People used a steelyard balance (杆秤) to weigh things. It had 16 gradations (秤星) on its arm. Each gradation stands for one star in the sky. The 16 gradations stand for 16 stars – the Big Dipper (北斗七星), Sagittarius and the stars of fortune, prosperity and longevity (福禄寿星). It was said that if you cheated someone while trading, you would lose the blessing (庇佑) of these stars. This helped to keep people honest while trading. After 1949, China started to do more international trade. To make things easier, we changed 16 liang for one jin into 10 liang for one jin. 1．From the text, “caigaobadou” first mainly described a talented person, his name was ________.

Many people have a special number and they hope that it will bring them good luck. In China, people think some numbers are lucky or unlucky because those numbers sound similar to some Chinese words with good or bad meanings. For example, the word for number 8 sounds like “making lots of money” in Chinese. So, people think it is a very lucky number. Some people even spend much more money to have 8s in their phone numbers. Do you remember the Summer Olympic Games in Beijing? It opened at 8:00 p.m. on August 8, 2008 The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on the emperors’ robes (龙袍) and it’s told in many ancient Chinese stories that the dragon has nine children. The number 9 also means “long lasting”. In China, a man would send 99 or 999 roses to his lover with the wishes that the love between them will be long-lasting. What’s more, the Chinese think that the number 2 is lucky as it’s said that “all good things come in pairs”. For example, during wedding celebrations, you usually find pairs of red candles, double pillows and many other things in pairs. And people often give gifts in pairs for someone’s birthday, wedding or other celebrations. So what’s an unlucky number in China? It might be 4. Many Chinese people see 4 as an unlucky number because it sounds similar to the Chinese word “death”. Because of this, many buildings skip the fourth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as 4, 14, 24 and 34. As a result, a building with 50 floors may have only 36 floors actually. 1．What makes Chinese people believe a number is lucky or unlucky? A．The shape of the number. B．The quantity of the number.

The number π, for example, is an infinite decimal that has fascinated mathematicians for a long time. It is used in many areas of science and engineering. Another important number is zero, which was a great invention in the history of mathematics. Numbers also have cultural significance. In some cultures, certain numbers are considered lucky or unlucky. For instance, the number 7 is often seen as lucky in Western cultures.

However, there are a lot of number expressions (表达) that can help. Today, I will talk about expressions about numbers. Sometimes we can “kill two birds with one stone”. That is to say, we can complete two goals with only one effort or action. But we must remember that “two wrongs don’t make a right”. If someone does something bad to you, you should not do the same to him. When I was a young child in school, I liked learning Maths. My teacher used to “give me three cheers” when I did well in Maths, praising (赞扬) my hard work and good grades. When I was in high school, some of my friends once had trouble doing their schoolwork. In fact, they did not care if they could finish high school. But it seemed that they really got a surprise when they completed their studies and graduated from high school. They were on cloud nine. Nine times out of ten, students who do well in school often find good jobs. Some people work in an office doing the same things every day at nine-to-five jobs. However, it’s good to know happiness at work isn’t just about money. 1．What does the second paragraph mainly tell us? A．The ways to find answers. B．Two problems are difficult to solve.

It is celebrated as Pi (π) Day, a day to celebrate the number that many people know very well. The date copies from the first three numbers of Pi (π). March is the third month and the 14th means one and four. Altogether it is 3.14. Pi (π) comes wherever there are circles (圆). Pi has been known for thousands of years and gets its name from a Greek letter, π. The Greeks are believed to be the earliest to use the letter in maths. The first Pi Day was celebrated on March 14, 1988. San Francisco’s Exploratorium Science Museum started the event. The museum marks the day with a daylong celebration. March 14 is also the birthday of the famous scientist Albert Einstein. Princeton University, where Einstein lived for many years, celebrates Pi Day as well. March 14, 2009, was celebrated as National Pi Day. And March 14, 2019 also marked the one- year anniversary (周年纪念日) of the death of Stephen Hawking. And how do people celebrate the Pi (π) Day? Maybe you can try these ideas: Eat or make different kinds of pies (for example, apple pies, cherry pies, and even pizza pies); Celebrate the day with a pie cut using the mathematical constant (常数) of Pi (π); Discuss the importance of the letter π; Watch Life of Pi in cinemas; Look for the number 3.14 in every place (such as prices and street numbers). 1．Which of the following like to celebrate the Pi Day most probably?

The lucky number has become increasingly popular in daily life of modern society (现代社会). For example, the number eight means big money which some people like most, while the number four means death. Some people believe lucky numbers so much that they will even buy a telephone with numbers without four and others which are bad in their mind. They think that the lucky number really can come with good luck, and, at least, no evidence (证据) can show that they can not. According to what I’ve found, there is no such relationship between the numbers and luck. And, in addition (此外), man should not depend on the luck which, in their mind, the numbers give them. 1．The underlined word “increasingly” means ________.

A．money B．lucky numbers C．themselves D．their parents （10） Many people hope lucky numbers will bring them good luck. In Chinese culture, some numbers are believed to be lucky or unlucky according to the Chinese characters that the number sounds similar to. For example, the number 8 sounds similar to the Chinese character for “making a fortune(发财)”. So people think it’s a lucky number. Some even spend a lot of money having the number 8 in their phone numbers or vehicle license plate numbers. The opening ceremony of the Beijing Olympics Games began at 8:08 p.m. on 8 August, 2008. The number 9 is also a lucky number because of its connection to the emperors(皇帝) of ancient China. There were nine dragons on the emperors’ robes(袍). It’s said that the dragon has nine children. The number 9 also stands for “long lasting”. That’s why a man always gives a woman 99 or 999 roses. Then what’s the unlucky number in China? It might be the number 4. Many Chinese people take 4 as an unlucky number because it sounds similar to the Chinese character for “death”. Because of this, some buildings skip the fourth floor, and people simply call it the fifth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as 4, 14, 24, 34, and all 40-49 floors. However, in many Western countries, some buildings skip the 13th floor because 13 is considered as an unlucky number. 1．In China, for which character does the number 8 sound similar to?
