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. 21．From the text, “caigaobadou” first mainly described a talented person, his name was ________. A．Cao Cao B．Xie Lingyun C．the other poets D．Cao Zhi 22．What can we learn from Xie Lingyun’s words? A．He thinks highly of Cao Zhi’s talents. B．He thinks he deserves more dou than Cao Zhi. C．He looks down on all the other poets except himself. D．He thinks all poets should share the same amount of talent. 23．According to the text, how tall exactly was a 7-chi-tall man in the Three Kingdoms period? A．It was about 110cm. B．It was about 170cm. C．It was about 231cm D．It was about 248cm 24．Which of the following statements is not right? A．The idiom “caigaobadou” usually refers to a talented person. B．In ancient China, Dan only referred to how much talent a person had. C．The idiom “7-chi-tall man” usually refers to a man who is tall and strong. D．Before 1949, banjin weighed the same as eight liang. 25．How did the belief in the stars help keep people honest while trading? A．People who cheated others would lose the blessing of the stars. B．People who cheated others would gain the blessing of the stars. C．People who cheated others would become wealthy. D．The belief in the stars did not affect people’s honesty while trading. B How quickly can you count from one to ten? 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 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 (土著居民) 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 (部落) 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.” 26．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. 27．What can we learn according to Paragraph 2? A．People from China can make use of different finger positions to do the 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. 28．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 to stand for numbers. 29．The study of the Piraha tribe shows that ________. A．people all over the world know how to count B．people of the tribe have words for numbers C．some groups of people are not smart enough to count D．counting is not useful in the culture of the tribe 30．What is the main idea of the passage? A．People from different cultures have different ideas about numbers. B．Chinese people can count more easily on their fingers than Americans. C．In some aboriginal cultures, people don’t even know how to count. D．Some languages don’t have number words because people don’t need numbers. C Do you know the numbers 0—9 well? They are Arabic numerals. People use them to mark numbers now. But it’s not the only number system that people use. About 2,500 years ago, people in Rome used their hands to count. In Roman numerals, one finger means 1, two fingers means 2, three fingers means 3, four fingers means 4. If you want to say five, you can keep your four fingers close on one side and your thumb on the other side. Make each of your hands be five, then you’ll have ten. So in Rome, the numbers are “I, II, III, IV, V, VI, VII, VIII, IX, X”. Also, “L” means fifty, “C” means one hundred. “D” means five hundred and “M” means one thousand. But there is no zero in Roman numerals. Today, few people use them because they are difficult to write and count. But we can still see them on some watches and clocks. Today, most people use the Arabic numerals. They are easy to remember and write. They help people to count things every day. In fact, Indians first created and used the Arabic numerals. In the late 8th century, people in Arabic countries learned about them. Then the Arabic people took them into Europe. So people in Europe called them Arabic numerals. Today, people around the world use Arabic numerals and they help a lot. 31．Which of the following means five in Roman numerals? A．L. B．M. C．V. D．X. 32．What does the underlined word “them” in Paragraph 2 mean? A．Arabic numerals. B．Watches and clocks. C．Zero. D．Roman numerals. 33．What do we know about Arabic numerals? A．People in Rome didn’t use them. B．Arabic people taught the Indians about them. C．Only Arabic people use them today. D．“0” means “zero” in Arabic numerals. 34．Why are there few people using Roman numerals today? A．Because they are not easy to write and count. B．Because there are no Romans anymore. C．Because the numbers look stupid. D．Because they are hard to remember. 35．In what order did the following things happen? a. Arabic people learned about Arabic numerals. b. Indians created Arabic numerals. c. Arabic people took Arabic numerals into Europe. d. People all over the world use Arabic numerals. A．b—c—a—d B．b—a—c—d C．d—b—a—c D．d—c—b—a 第二节 阅读填空（共5小题， 每小题1分，共5分） 以下是一篇短文，请阅读全文，并从下列六个句子中选择五个还原到原文中，使原文意思完整、连贯。 Do you like the number 13? 36 In the past, a lot of tall buildings didn’t have the 13th floor. 37 For example, the number “4” is said to be unlucky because it sounds like the Chinese word for “death”. But that’s just one example about numbers in China. When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. I soon found that this is actually convenient, as Chinese characters (汉字) cannot be used for website addresses. 38 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. 39 In addition, the pronunciations of some numbers sound similar to other words in Chinese. This is wordplay (双关语). For example, the numbers “520” in Chinese sound similar to the pronunciation of the Chinese phrase “I love you”. 40 A．They can only use numbers or letters instead. B．There are also superstitions (迷信) about some numbers in China. C．In western countries, some people think the number 13 brings bad luck. D．It is interesting to see how Chinese people use numbers in different ways. E．So instead, they used the hotline number—10010.com. This is easier to type and remember. F．Many couples choose to get married on May 20th for this reason. 三、项目情景(共两节,满分20分) 第一节 配对阅读(共5小题,每小题2分,满分10分) 左栏是五个学生的情况描述，右栏是七条关于礼物的建议。请为每个人选择合适的建议，并将答题卡上对应题目所选的选项涂黑。 41 Jack wants to buy a birthday present for his best friend Lucy.

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. 21．From the text, “caigaobadou” first mainly described a talented person, his name was ________. A．Cao Cao B．Xie Lingyun C．the other poets D．Cao Zhi 22．What can we learn from Xie Lingyun’s words? A．He thinks highly of Cao Zhi’s talents. B．He thinks he deserves more dou than Cao Zhi. C．He looks down on all the other poets except himself. D．He thinks all poets should share the same amount of talent. 23．According to the text, how tall exactly was a 7-chi-tall man in the Three Kingdoms period? A．It was about 110cm. B．It was about 170cm. C．It was about 231cm D．It was about 248cm 24．Which of the following statements is not right? A．The idiom “caigaobadou” usually refers to a talented person. B．In ancient China, Dan only referred to how much talent a person had. C．The idiom “7-chi-tall man” usually refers to a man who is tall and strong. D．Before 1949, banjin weighed the same as eight liang. 25．How did the belief in the stars help keep people honest while trading? A．People who cheated others would lose the blessing of the stars. B．People who cheated others would gain the blessing of the stars. C．People who cheated others would become wealthy. D．The belief in the stars did not affect people’s honesty while trading. 【答案】21．D 22．A 23．B 24．B 25．A 【导语】本文讲述了几个含有数字的汉语成语的意思，表达了汉语的博大精深。 【详解】21．细节理解题。根据“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.”可知，根据谢灵运的说法，天下才气为一担，曹植占据8斗，自己占据一斗，其余占一斗。所以“才高八斗”开始指曹植。故选D。 22．推理判断题。根据文章可知，谢灵运的话表明他高度评价曹植的才华，认为曹植拥有八斗才华，而自己和其他诗人总共只占两斗。故选A。 23．细节理解题。根据“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.”可知，七尺大约是170厘米。故选B。 24．细节理解题。根据“Heaven only gave the world one dan of talent,”及“The dan used was an ancient Chinese measurement for grain. One dan is equal to 10 dou.”可知，在中国古代，担只指一个人有多少天赋的表述错误。故选B。 25．细节理解题。根据“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.”可知，如果你在交易时欺骗了别人，你就会失去这些天上星宿的祝福。这有助于人们在交易时保持诚实。故选A。 B How quickly can you count from one to ten? 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 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 (土著居民) 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 (部落) 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.” 26．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. 27．What can we learn according to Paragraph 2? A．People from China can make use of different finger positions to do the 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. 28．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 to stand for numbers. 29．The study of the Piraha tribe shows that ________. A．people all over the world know how to count B．people of the tribe have words for numbers C．some groups of people are not smart enough to count D．counting is not useful in the culture of the tribe 30．What is the main idea of the passage? A．People from different cultures have different ideas about numbers. B．Chinese people can count more easily on their fingers than Americans. C．In some aboriginal cultures, people don’t even know how to count. D．Some languages don’t have number words because people don’t need numbers. 【答案】26．B 27．A 28．A 29．D 30．A 【导语】本文是一篇说明文，文章主要探讨了不同文化背景下人们对数字的理解和计数方式存在差异。通过举例不同地区的人们手指计数的方法，以及一些没有数字词汇的部落，说明文化和语言对数字认知的影响。 【详解】26．推理判断题。根据文章第一段“How quickly can you count from one to ten? 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?”可知，作者在文章开头列出了四个问题，这些问题与读者的日常生活相关，且具有一定的趣味性，其目的是吸引读者的兴趣，引导读者继续阅读。故选B。 27．细节理解题。根据文章第二段“In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand.”可知，中国人可以通过使用不同的手指位置来进行计数，因此，中国人可以利用不同的手指位置来进行计数。故选A。 28．细节理解题。根据文章第三段“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.”可知，澳大利亚的土著居民没有代表数字的手势，甚至没有代表数字的词汇，但他们仍然能够理解关于数字的不同概念，说明他们的生活中有数字的概念。故选A。 29．细节理解题。根据文章第四段“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.’”可知，麻省理工学院的Edward Gibson教授表示，大多数人认为每个人都知道如何计数，但有一个群体不会计数，他们可以学习，但在他们的文化中没有用，所以他们从来没有学过，这说明计数在该部落的文化中没有用。故选D。 30．主旨大意题。根据文章第三段“Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers.”以及全文内容可知，文章主要探讨了不同文化背景下人们对数字的理解和计数方式存在差异，通过举例不同地区的人们手指计数的方法，以及一些没有数字词汇的部落，说明文化和语言对数字认知的影响，因此文章的主旨大意是不同文化背景的人对数字有不同的理解。故选A。 C Do you know the numbers 0—9 well? They are Arabic numerals. People use them to mark numbers now. But it’s not the only number system that people use. About 2,500 years ago, people in Rome used their hands to count. In Roman numerals, one finger means 1, two fingers means 2, three fingers means 3, four fingers means 4. If you want to say five, you can keep your four fingers close on one side and your thumb on the other side. Make each of your hands be five, then you’ll have ten. So in Rome, the numbers are “I, II, III, IV, V, VI, VII, VIII, IX, X”. Also, “L” means fifty, “C” means one hundred. “D” means five hundred and “M” means one thousand. But there is no zero in Roman numerals. Today, few people use them because they are difficult to write and count. But we can still see them on some watches and clocks. Today, most people use the Arabic numerals. They are easy to remember and write. They help people to count things every day. In fact, Indians first created and used the Arabic numerals. In the late 8th century, people in Arabic countries learned about them. Then the Arabic people took them into Europe. So people in Europe called them Arabic numerals. Today, people around the world use Arabic numerals and they help a lot. 31．Which of the following means five in Roman numerals? A．L. B．M. C．V. D．X. 32．What does the underlined word “them” in Paragraph 2 mean? A．Arabic numerals. B．Watches and clocks. C．Zero. D．Roman numerals. 33．What do we know about Arabic numerals? A．People in Rome didn’t use them. B．Arabic people taught the Indians about them. C．Only Arabic people use them today. D．“0” means “zero” in Arabic numerals. 34．Why are there few people using Roman numerals today? A．Because they are not easy to write and count. B．Because there are no Romans anymore. C．Because the numbers look stupid. D．Because they are hard to remember. 35．In what order did the following things happen? a. Arabic people learned about Arabic numerals. b. Indians created Arabic numerals. c. Arabic people took Arabic numerals into Europe. d. People all over the world use Arabic numerals. A．b—c—a—d B．b—a—c—d C．d—b—a—c D．d—c—b—a 【答案】31．C 32．D 33．D 34．A 35．B 【导语】本文主要介绍了罗马数字和阿拉伯数字的相关信息，包括罗马数字的计数方式、阿拉伯数字的起源与传播等。 【详解】31．细节理解题。根据“Make each of your hands be five, then you’ll have ten. So in Rome, the numbers are ‘I, II, III, IV, V...’”可知，罗马数字中“V”表示5。故选C。 32．词句猜测题。根据“But there is no zero in Roman numerals. Today, few people use them because they are difficult to write and count. But we can still see them on some watches and clocks.”可知，them指代前文提到的“Roman numerals (罗马数字)”，因为罗马数字没有零，且难以书写和计数，所以现在很少有人使用。故选D。 33．细节理解题。根据“Do you know the numbers 0—9 well? They are Arabic numerals.”以及“But there is no zero in Roman numerals.”可知，阿拉伯数字中包含“0”，而罗马数字中没有。故选D。 34．细节理解题。根据“Today, few people use them because they are difficult to write and count.”可知，如今很少有人使用罗马数字是因为它们难以书写和计数。故选A。 35．细节理解题。根据“In fact, Indians first created and used the Arabic numerals. In the late 8th century, people in Arabic countries learned about them. Then the Arabic people took them into Europe. So people in Europe called them Arabic numerals. Today, people around the world use Arabic numerals and they help a lot.”可知，印度人首创阿拉伯数字，阿拉伯人后来了解了它们，并将其带入欧洲，最后全世界都在使用阿拉伯数字。因此，正确顺序为b—a—c—d。故选B。 第二节 阅读填空（共5小题， 每小题1分，共5分） 以下是一篇短文，请阅读全文，并从下列六个句子中选择五个还原到原文中，使原文意思完整、连贯。 Do you like the number 13? 36 In the past, a lot of tall buildings didn’t have the 13th floor. 37 For example, the number “4” is said to be unlucky because it sounds like the Chinese word for “death”. But that’s just one example about numbers in China. When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. I soon found that this is actually convenient, as Chinese characters (汉字) cannot be used for website addresses. 38 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. 39 In addition, the pronunciations of some numbers sound similar to other words in Chinese. This is wordplay (双关语). For example, the numbers “520” in Chinese sound similar to the pronunciation of the Chinese phrase “I love you”. 40 A．They can only use numbers or letters instead. B．There are also superstitions (迷信) about some numbers in China. C．In western countries, some people think the number 13 brings bad luck. D．It is interesting to see how Chinese people use numbers in different ways. E．So instead, they used the hotline number—10010.com. This is easier to type and remember. F．Many couples choose to get married on May 20th for this reason. 【答案】36．C 37．B 38．A 39．E 40．F 【导语】本文介绍了数字在文化中的特殊意义以及它们在网站名称中的应用；文章还提到了一些数字与中文词语发音相似，形成有趣的双关语现象。 【详解】36．根据上文“Do you like the number 13? ”可知，此处是人们对于数字13的看法；选项C“在西方国家，有些人认为数字13会带来厄运。”符合语境。故选C。 37．根据下文“For example, the number ‘4’ is said to be unlucky because it sounds like the Chinese word for ‘death’.”可知，中国文化中对数字也有迷信的说法；选项B“在中国也有一些关于数字的迷信。”符合语境。故选B。 38．根据上文“I soon found that this is actually convenient, as Chinese characters (汉字) cannot be used for website addresses.”可知，汉字不能在网址上用，所以此处是介绍什么可以用在网址上；选项A“它们只能用数字或字母来代替。”符合语境。故选A。 39．根据上文“If the company used their pinyin name for their website address, it would be quite long.”可知，中国联通使用拼音导致网址太长，所以他们采用了数字；选项E“因此，他们使用了热线电话10010.com。这样更容易打字和记忆。”符合语境。故选E。 40．根据上文“For example, the numbers ‘520’ in Chinese sound similar to the pronunciation of the Chinese phrase ‘I love you’. ”可知，520的谐音是“我爱你”；选项F“出于这个原因，许多情侣选择在5月20日结婚。”符合语境。故选F。 三、项目情景(共两节,满分20分) 第一节 配对阅读(共5小题,每小题2分,满分10分) 左栏是五个学生的情况描述，右栏是七条关于礼物的建议。请为每个人选择合适的建议，并将答题卡上对应题目所选的选项涂黑。 41 Jack wants to buy a birthday present for his best friend Lucy.

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. 21．From the text, “caigaobadou” first mainly described a talented person, his name was ________. A．Cao Cao B．Xie Lingyun C．the other poets D．Cao Zhi 22．What can we learn from Xie Lingyun’s words? A．He thinks highly of Cao Zhi’s talents. B．He thinks he deserves more dou than Cao Zhi. C．He looks down on all the other poets except himself. D．He thinks all poets should share the same amount of talent. 23．According to the text, how tall exactly was a 7-chi-tall man in the Three Kingdoms period? A．It was about 110cm. B．It was about 170cm. C．It was about 231cm D．It was about 248cm 24．Which of the following statements is not right? A．The idiom “caigaobadou” usually refers to a talented person. B．In ancient China, Dan only referred to how much talent a person had. C．The idiom “7-chi-tall man” usually refers to a man who is tall and strong. D．Before 1949, banjin weighed the same as eight liang. 25．How did the belief in the stars help keep people honest while trading? A．People who cheated others would lose the blessing of the stars. B．People who cheated others would gain the blessing of the stars. C．People who cheated others would become wealthy. D．The belief in the stars did not affect people’s honesty while trading. B How quickly can you count from one to ten? 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 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 (土著居民) 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 (部落) 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.” 26．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. 27．What can we learn according to Paragraph 2? A．People from China can make use of different finger positions to do the 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. 28．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 to stand for numbers. 29．The study of the Piraha tribe shows that ________. A．people all over the world know how to count B．people of the tribe have words for numbers C．some groups of people are not smart enough to count D．counting is not useful in the culture of the tribe 30．What is the main idea of the passage? A．People from different cultures have different ideas about numbers. B．Chinese people can count more easily on their fingers than Americans. C．In some aboriginal cultures, people don’t even know how to count. D．Some languages don’t have number words because people don’t need numbers. C Do you know the numbers 0—9 well? They are Arabic numerals. People use them to mark numbers now. But it’s not the only number system that people use. About 2,500 years ago, people in Rome used their hands to count. In Roman numerals, one finger means 1, two fingers means 2, three fingers means 3, four fingers means 4. If you want to say five, you can keep your four fingers close on one side and your thumb on the other side. Make each of your hands be five, then you’ll have ten. So in Rome, the numbers are “I, II, III, IV, V, VI, VII, VIII, IX, X”. Also, “L” means fifty, “C” means one hundred. “D” means five hundred and “M” means one thousand. But there is no zero in Roman numerals. Today, few people use them because they are difficult to write and count. But we can still see them on some watches and clocks. Today, most people use the Arabic numerals. They are easy to remember and write. They help people to count things every day. In fact, Indians first created and used the Arabic numerals. In the late 8th century, people in Arabic countries learned about them. Then the Arabic people took them into Europe. So people in Europe called them Arabic numerals. Today, people around the world use Arabic numerals and they help a lot. 31．Which of the following means five in Roman numerals? A．L. B．M. C．V. D．X. 32．What does the underlined word “them” in Paragraph 2 mean? A．Arabic numerals. B．Watches and clocks. C．Zero. D．Roman numerals. 33．What do we know about Arabic numerals? A．People in Rome didn’t use them. B．Arabic people taught the Indians about them. C．Only Arabic people use them today. D．“0” means “zero” in Arabic numerals. 34．Why are there few people using Roman numerals today? A．Because they are not easy to write and count. B．Because there are no Romans anymore. C．Because the numbers look stupid. D．Because they are hard to remember. 35．In what order did the following things happen? a. Arabic people learned about Arabic numerals. b. Indians created Arabic numerals. c. Arabic people took Arabic numerals into Europe. d. People all over the world use Arabic numerals. A．b—c—a—d B．b—a—c—d C．d—b—a—c D．d—c—b—a 第二节 阅读填空（共5小题， 每小题1分，共5分） 以下是一篇短文，请阅读全文，并从下列六个句子中选择五个还原到原文中，使原文意思完整、连贯。 Do you like the number 13? 36 In the past, a lot of tall buildings didn’t have the 13th floor. 37 For example, the number “4” is said to be unlucky because it sounds like the Chinese word for “death”. But that’s just one example about numbers in China. When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. I soon found that this is actually convenient, as Chinese characters (汉字) cannot be used for website addresses. 38 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. 39 In addition, the pronunciations of some numbers sound similar to other words in Chinese. This is wordplay (双关语). For example, the numbers “520” in Chinese sound similar to the pronunciation of the Chinese phrase “I love you”. 40 A．They can only use numbers or letters instead. B．There are also superstitions (迷信) about some numbers in China. C．In western countries, some people think the number 13 brings bad luck. D．It is interesting to see how Chinese people use numbers in different ways. E．So instead, they used the hotline number—10010.com. This is easier to type and remember. F．Many couples choose to get married on May 20th for this reason. 三、项目情景(共两节,满分20分) 第一节 配对阅读(共5小题,每小题2分,满分10分) 左栏是五个学生的情况描述，右栏是七条关于礼物的建议。请为每个人选择合适的建议，并将答题卡上对应题目所选的选项涂黑。 41 Jack wants to buy a birthday present for his best friend Lucy.
