Do you have a lucky number What is it Many people have a special number that they hope will bring them good luck.
In Chinese culture, some numbers are believed to be lucky or unlucky based on the Chinese word that the number sounds similar to.
For example, the word for the number 8 sounds similar to the word for “making a fortune (发财)”. So, people consider it a very lucky number. Some people will even spend a lot of money to have 8s in their phone number or on their vehicle license plate (车牌照) number. The opening ceremony of the Beijing Olympics began at 8:08 p.m. on Aug. 8, 2008.
The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on emperors’ robes (龙袍) and Chinese myth held that the dragon had nine children. The number 9 also stands for “long lasting”. That’ s why a man always proposes (求婚) to a woman with 99 or 999 roses.
So, what’s an unlucky number in China One example is 4. Many Chinese people see 4 as an unlucky number because it sounds similar to the character for “death”.
Because of this, many buildings skip (跳过) the fourth floor, and 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. Some buildings also skip the 13th floor, as this is considered an unlucky number in some areas in Hong Kong. As a result, a building whose highest floor is 50 may have only 35 physical floors.
5. What makes Chinese people believe a number is lucky or unlucky
A. The shape of the number. B. The sound of the number.
C. The history of the number. D. The spelling of the number.
6. A building whose highest floor is 60 in Hong Kong might only have ________ physical floors if it skips all the unlucky numbers.
A. 35 B. 60 C. 45 D. 44
7. According to the passage, the meaning of number 9 in Chinese culture is _________.
A. fortunate B. ordinary C. everlasting D. simple
8. What is the passage mainly about
A. Numbers and old stories in China.
B. Lucky and unlucky numbers in Chinese culture.
C. Ways to find your lucky and unlucky numbers.
D. Different meanings of numbers in different countries.
【答案】5. B 6. D 7. C 8. B
【解析】本文主要介绍了中国文化中的幸运数字和不幸运数字。
5. 细节理解题。根据“In Chinese culture, some numbers are believed to be lucky or unlucky based on the Chinese word that the number sounds similar to.”可知，在中国文化中，人们认为数字是否幸运是基于数字的发音。故选B。
6. 推理判断题。根据“In Hong Kong, some buildings even skip all floors numbered with 4”可知，香港的一些建筑会跳过所有带有4的楼层，因此，最高60层的建筑要排除4、14、24、34、44、54、40～49，因此实际只有44层。故选D。
7. 细节理解题。根据“The number 9 also stands for ‘long lasting’.”可知，数字9在中国文化中代表“长久”，即“everlasting”。故选C。
8. 主旨大意题。根据文章内容可知，本文主要介绍了中国文化中的幸运数字和不幸运数字。故选B。
C
Many of us may have experienced the pleasant moment of seeing recommended songs after we listen to some songs on a music app. When we open shopping websites, we often see things we want to buy on the home page. The businessman can decide which is the best place to build a new entrance in a big supermarket in the city center. If you want to take a taxi on a taxi app, it can even guess where you want to go before you tell it! Aren’t these things amazing
This is based on data (数据). Data is no longer only about numbers, but information from almost every side of our lives: our shopping habits, interests or what we eat. All of this is called “big data”. In December, 2017, President Xi Jinping called for China to speed up its big data strategy (战略) to better serve social and economic (经济的) development. As a result, people’s lives can be improved as well. He also asked for greater use of big data in areas like education, social security and transportation.
We have seen big data being used more often in China in the past few years. The role it plays in tourism (旅游业) is just one example. Many travelers today like to share their experiences with others on the Internet. All the data that travelers share online is helping the tourism industry get a lot of information. After the data is analyzed (分析), these tour sights can know about travelers’ needs better. In this way, services will be improved, which is helpful to the development of the whole industry. As a result, travelers can expect better tours in the future.
Moreover, big data is also an important growth tool for economic development. With growth rate of 30 percent every year, sales of big data industry in China will reach one trillion yuan yearly by 2020. Having so many good influences, big data is sure to be seen more and more in China.

Take a pen and write the number 6174 on a piece of paper. It looks just like any other number, doesn’t it But what if I told you that it was a magic number
Do you think this is a joke Well, let’s see the magic with a quick experiment (实验).
Start with any four-digit (数字) number—just make sure that at least two of the digits are different. You may use, for example, 2024.
Now rearrange the digits to make the smallest possible number: 0224. Then, arrange the digits to make the largest number: 4220. Let’s subtract the smaller number from the larger number:
4220-0224= 3996.
Go back to the second step and repeat the process:
9963-3699=6264 6642-2466=4176 7641-1467=6174
Ta-da! There you have it: 6174!
You can repeat this experiment with another number. What do you end up with Is it 6174
This number is known as Kaprekar’s constant. It is named after the Indian mathematician Dattatreya Ramchandra Kaprekar. He discovered (发现) the magic behind this number in 1949 after performing the above process.
Kaprekar had always enjoyed playing with numbers. After finishing college, he spent his life working as a primary school math teacher. The man was known for his sharp mind. Many schools and colleges invited him to solve difficult math problems.
But when Kaprekar presented the magic of 6174 at an international mathematics meeting, other mathematicians didn’t roll out the red carpet. They thought it was a useless discovery and made fun of him. Yet to this day, no scientist can fully tell why this magic works.

39. 句意：当他回到家时，他为没有找到宝藏向父亲道歉。find“找到”，动词，介词for后接动名词形式。故填finding。

四、阅读与表达（共4小题,41 43小题，每题2分,44小题4分；满分10分）
阅读短文，然后根据内容回答问题。
Do you often compare yourself to other people Perhaps your best friend received something you really wanted for birthday, or you’re not allowed to go to a concert but your brother or sister is. Even though comparisons are normal and sometimes helpful, focusing on your own progress is important for your happiness, too.
Why is focusing on me important “We prefer to compare ourselves to others who are doing better or not as well as ourselves,” says psychologist (心理学家) Nicola Abbott. “But comparing your achievements to your past self and your future self can be more positive.” This can make you feel proud and excited.
If you begin to feel quite low, Abbott suggests focusing on your own progress and what you’re good at. You can ask yourself questions like “ ▲ ”, “What do I feel proud of ” and “What improvements can I notice ” These can help to improve your self-esteem (自尊心).
“Comparing with others is normal,” says Antrobus, a child psychologist, “but focusing on improving your own performance can help you feel successful, too. Besides, learning to celebrate your friend’s achievements can help not only to, improve your friend’s feeling but can also help you feel good. “It will encourage you to get along well with each other.”
41. What does the writer think of comparisons
42. What can make you feel proud and excited according to Paragraph 2
43. What might be the missing sentence in the ▲
44. Which do you think is more helpful to you, comparing with others or focusing on your own progress Why （30 words or more）
【答案】41. The writer thinks comparisons are normal and sometimes helpful. 42. Comparing your achievements to your past self and your future self. 43. 开放性试题，言之有理即可。参考答案为What am I good at 44. 开放性试题，答案不唯一，结合实际情况作答。参考答案为Focusing on my own progress. It can make me feel proud of what I have achieved and excited about what I might do. It can also help me feel good about myself and encourage me to make more progress in the future.
【解析】本文作者告诉我们，我们应该专注于自己的进步，和自己的过去和未来比较，而不是与别人比较。

Do you have a lucky number What is it Many people have a special number that they hope will bring them good luck.
In Chinese culture, some numbers are believed to be lucky or unlucky based on the Chinese word that the number sounds similar to.
For example, the word for the number 8 sounds similar to the word for “making a fortune (发财)”. So, people consider it a very lucky number. Some people will even spend a lot of money to have 8s in their phone number or on their vehicle license plate (车牌照) number. The opening ceremony of the Beijing Olympics began at 8:08 p.m. on Aug. 8, 2008.
The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on emperors’ robes (龙袍) and Chinese myth held that the dragon had nine children. The number 9 also stands for “long lasting”. That’ s why a man always proposes (求婚) to a woman with 99 or 999 roses.
So, what’s an unlucky number in China One example is 4. Many Chinese people see 4 as an unlucky number because it sounds similar to the character for “death”.
Because of this, many buildings skip (跳过) the fourth floor, and 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. Some buildings also skip the 13th floor, as this is considered an unlucky number in some areas in Hong Kong. As a result, a building whose highest floor is 50 may have only 35 physical floors.
5. What makes Chinese people believe a number is lucky or unlucky
A. The shape of the number. B. The sound of the number.
C. The history of the number. D. The spelling of the number.
6. A building whose highest floor is 60 in Hong Kong might only have ________ physical floors if it skips all the unlucky numbers.
A. 35 B. 60 C. 45 D. 44
7. According to the passage, the meaning of number 9 in Chinese culture is _________.
A. fortunate B. ordinary C. everlasting D. simple
8. What is the passage mainly about
A. Numbers and old stories in China.
B. Lucky and unlucky numbers in Chinese culture.
C. Ways to find your lucky and unlucky numbers.
D. Different meanings of numbers in different countries.

Many of us may have experienced the pleasant moment of seeing recommended songs after we listen to some songs on a music app. When we open shopping websites, we often see things we want to buy on the home page. The businessman can decide which is the best place to build a new entrance in a big supermarket in the city center. If you want to take a taxi on a taxi app, it can even guess where you want to go before you tell it! Aren’t these things amazing
This is based on data (数据). Data is no longer only about numbers, but information from almost every side of our lives: our shopping habits, interests or what we eat. All of this is called “big data”. In December, 2017, President Xi Jinping called for China to speed up its big data strategy (战略) to better serve social and economic (经济的) development. As a result, people’s lives can be improved as well. He also asked for greater use of big data in areas like education, social security and transportation.
We have seen big data being used more often in China in the past few years. The role it plays in tourism (旅游业) is just one example. Many travelers today like to share their experiences with others on the Internet. All the data that travelers share online is helping the tourism industry get a lot of information. After the data is analyzed (分析), these tour sights can know about travelers’ needs better. In this way, services will be improved, which is helpful to the development of the whole industry. As a result, travelers can expect better tours in the future.
Moreover, big data is also an important growth tool for economic development. With growth rate of 30 percent every year, sales of big data industry in China will reach one trillion yuan yearly by 2020. Having so many good influences, big data is sure to be seen more and more in China.
9. Data from travelers is analyzed in order to ______.
A. share travelling experiences online

C. improve services of the tour sights
D. know the needs of tour sights better
10. After reading the passage, we know that ______.

B. people have few chances to use big data at present in China
C. sales of big data industry are growing fast every year by 30%
D. big data improve people’s life before the social development can be realized
11. Which of the following words can describe the writer’s feeling towards big data
A. Sad. B. Bored. C. Hopeful. D. Careful.
12. What can be the best title for the passage

Take a pen and write the number 6174 on a piece of paper. It looks just like any other number, doesn’t it But what if I told you that it was a magic number
Do you think this is a joke Well, let’s see the magic with a quick experiment (实验).
Start with any four-digit (数字) number—just make sure that at least two of the digits are different. You may use, for example, 2024.
Now rearrange the digits to make the smallest possible number: 0224. Then, arrange the digits to make the largest number: 4220. Let’s subtract the smaller number from the larger number:
4220-0224= 3996.
Go back to the second step and repeat the process:
9963-3699=6264 6642-2466=4176 7641-1467=6174
Ta-da! There you have it: 6174!
You can repeat this experiment with another number. What do you end up with Is it 6174
This number is known as Kaprekar’s constant. It is named after the Indian mathematician Dattatreya Ramchandra Kaprekar. He discovered (发现) the magic behind this number in 1949 after performing the above process.
Kaprekar had always enjoyed playing with numbers. After finishing college, he spent his life working as a primary school math teacher. The man was known for his sharp mind. Many schools and colleges invited him to solve difficult math problems.
But when Kaprekar presented the magic of 6174 at an international mathematics meeting, other mathematicians didn’t roll out the red carpet. They thought it was a useless discovery and made fun of him. Yet to this day, no scientist can fully tell why this magic works.
Would you like to dive deeper Try different numbers and see how many steps you need to get to 6174. Which number needs the most calculations How about the least
13. How does the writer start the passage
A. By using sayings. B. By giving an example.
C. By telling a story. D. By asking questions.
14. To start the experiment, which of the following numbers should you choose
A. 76. B. 111. C. 1914. D. 6666.
15. What does the underlined phrase mean in the passage
A. Show little interest. B. Give a warm welcome.
C. Have a good laugh. D. Disagree with his belief.
16. What’s the purpose of this passage
A. To introduce a magic number 6174 and the story behind its discovery.
B. To show people that Kaprekar was a great mathematician.
C. To teach people how to do math experiments with four-digit numbers.
D. To invite readers to become math teachers like Kaprekar.

Do you often compare yourself to other people Perhaps your best friend received something you really wanted for birthday, or you’re not allowed to go to a concert but your brother or sister is. Even though comparisons are normal and sometimes helpful, focusing on your own progress is important for your happiness, too.
Why is focusing on me important “We prefer to compare ourselves to others who are doing better or not as well as ourselves,” says psychologist (心理学家) Nicola Abbott. “But comparing your achievements to your past self and your future self can be more positive.” This can make you feel proud and excited.
If you begin to feel quite low, Abbott suggests focusing on your own progress and what you’re good at. You can ask yourself questions like “ ▲ ”, “What do I feel proud of ” and “What improvements can I notice ” These can help to improve your self-esteem (自尊心).
“Comparing with others is normal,” says Antrobus, a child psychologist, “but focusing on improving your own performance can help you feel successful, too. Besides, learning to celebrate your friend’s achievements can help not only to, improve your friend’s feeling but can also help you feel good. “It will encourage you to get along well with each other.”
41. What does the writer think of comparisons
42. What can make you feel proud and excited according to Paragraph 2
