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. 61．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. 62．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 63．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. 64．In Hong Kong, you may NOT find the ________ floor in some buildings. A．50th B．35th C．46th D．17th 65．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.

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. 83 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. 84 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”. 85 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】81．C 82．B 83．A 84．E 85．F 你有在外租房的经验吗？以下右栏是出租房的广告信息，请根据左栏五位租客的租房要求配对。从A—E中选出对应的答案填入空白处。 86 Jackson has just graduated from a university and he wants to rent a small and cheap house. 87 Mr and Mrs. Robinson want to live in a town with their four children.

Small house in the country, 2 miles from the village, but near the bus stop, $480 a month. 【答案】86．E 87．C 88．A 89．B 90．F Some problems are difficult to solve in our life. 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. 91．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. 92．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. 93．What do the underlined words “on cloud nine” mean? A．Sad. B．Joyful. C．Surprised. D．Afraid. 94．Which of the following is TRUE? A．Students who study well often find good jobs. B．When someone hurts you, you should hurt him back. C．All problems can be solved easily with number expressions. D．The writer’s favourite subject was Maths when he was young. 95．What’s the main purpose of the passage? A．To encourage us to study hard. 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. 【答案】91．D 92．C 93．B 94．A 95．C 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).

On March 22nd, World Water Day draws attention (注意力) to the importance of water in our lives, the problems many people have getting clean water, and solutions (解决方法) to these problems. Why do we need water? The human body is around 60% water, and we need to drink lots of water to be healthy. As well as needing clean water to drink, we need it for cooking, washing and brushing our teeth. Farmers use water to make the plants grow. We also use a lot of water to make clothes. Do you know that it takes about 2,700 kilos of water to make one T-shirt? Does everyone have enough water? We all need water to live, but more than two billion people around the world live without clean water. Many of them live in the countryside or in places where there is a war (战争). Some people live in the desert and it is very hot, so it is very hard for them to get water. If we drink dirty water, we will be ill (生病的). In some countries, women and children walk many kilometers every day to get water, and sometimes the water isn’t even clean! If children spend most of their day walking to get water, they can’t go to school. What do people do on World Water Day? On World Water Day, many countries hold activities to tell people about the problems of dirty water and to try to find ways to provide everyone with clean water. They make posters to tell the importance of saving water. They also sell old books to raise money to help. 101．When is World Water Day? 102．What do farmers use water for? 103．How much water does it take to make a T-shirt? 104．What will happen if we drink dirty water? 105．Would you like to take part in World Water Day activities?

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. 61．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. 62．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 63．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. 64．In Hong Kong, you may NOT find the ________ floor in some buildings. A．50th B．35th C．46th D．17th 65．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. 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.

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. 83 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. 84 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”. 85 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. 你有在外租房的经验吗？以下右栏是出租房的广告信息，请根据左栏五位租客的租房要求配对。从A—E中选出对应的答案填入空白处。 86 Jackson has just graduated from a university and he wants to rent a small and cheap house. 87 Mr and Mrs. Robinson want to live in a town with their four children.

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. 91．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. 92．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. 93．What do the underlined words “on cloud nine” mean? A．Sad. B．Joyful. C．Surprised. D．Afraid. 94．Which of the following is TRUE? A．Students who study well often find good jobs. B．When someone hurts you, you should hurt him back. C．All problems can be solved easily with number expressions. D．The writer’s favourite subject was Maths when he was young. 95．What’s the main purpose of the passage? A．To encourage us to study hard. 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. 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).

Some people live in the desert and it is very hot, so it is very hard for them to get water. If we drink dirty water, we will be ill (生病的). In some countries, women and children walk many kilometers every day to get water, and sometimes the water isn’t even clean! If children spend most of their day walking to get water, they can’t go to school. What do people do on World Water Day? On World Water Day, many countries hold activities to tell people about the problems of dirty water and to try to find ways to provide everyone with clean water. They make posters to tell the importance of saving water. They also sell old books to raise money to help. 101．When is World Water Day? 102．What do farmers use water for? 103．How much water does it take to make a T-shirt? 104．What will happen if we drink dirty water? 105．Would you like to take part in World Water Day activities?

He was very good 116 solving maths problems and loved to help people with their calculations. One day, he received a letter from the Maths Kingdom. 117 letter said that a number had gone missing in the kingdom. The king asked Detective Maths 118 (help) his kingdom! Detective Maths packed 119 (he) notebook and pencil and set off. He soon arrived at the Maths Kingdom, a place filled with colourful numbers and 120 (friend) maths symbols. The king said, “Because of the missing number, all our calculations are wrong. I know you have the 121 (able) to solve this case (案件). Please help us.” Detective Maths started investigating (调查) by 122 (talk) to the numbers and symbols. He asked them if they had seen anything strange or unusual. The numbers and symbols said no. Then Detective Maths 123 (check) all the calculations in the Kingdom. After working out many maths problems and puzzles 124 (correct), Detective Maths finally found that the missing number was 5. He also discovered a number thief (小偷) hiding in a secret cave. The thief was a little number named Zero. Zero took away the missing number 125 he wanted to be the only number in the Maths Kingdom. Detective Maths told Zero that all numbers were important and that they needed to work together. How did people count things before the i 126 of written numbers? At first, people used their fingers, and even their toes. H 127 , they could only count small numbers in this way. After that, they began to make small marks on sticks and bones. This helped them count bigger numbers. They used them to count things like the days of the month, the a 128 of food and the number of animals they had. Then people began to use tokens made from clay or small stones. This helped them count even bigger numbers. They often put the tokens on pieces of string so that they could c 129 them around easily. This developed into tools like the abacus. Finally, people began to develop systems of written marks to show different numbers, and this l 130 to the Hindu-Arabic system (0-9). We are still using this system today. 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $$
