As a Chinese teenager, it is our duty to inherit and develop our traditional culture and spread it to the world. Chinese traditional culture includes a variety of forms, such as traditional festivals, folk art, traditional food and Chinese characters. Among them, traditional festivals are an important part of our culture. For example, the Spring Festival is the most important festival in China. During the Spring Festival, families get together to have a big dinner, paste Spring Festival couplets, set off fireworks and visit relatives and friends. It is a time to express love and blessings to our family and friends. Folk art is another precious part of Chinese traditional culture. Peking Opera, paper-cutting and embroidery are all famous folk arts in China. Peking Opera, known as the “national opera” of China, combines singing, dancing, acting and music. Paper-cutting is a simple but beautiful art form; people use scissors to cut paper into various shapes, such as flowers, animals and characters, to express their good wishes. In recent years, with the help of modern technology, Chinese traditional culture has been spread more widely. Many traditional cultural works have been made into cartoons, movies and online programs, which are popular among young people. More and more foreigners begin to learn Chinese, understand Chinese traditional culture and fall in love with China. We should cherish our traditional culture, learn more about it and pass it on to the next generation. Only in this way can our traditional culture be kept alive and develop better in the future. 1.

B In the 21st century, science and technology are developing at an unprecedented speed, and they have a great influence on our daily life. From the moment we get up in the morning to the time we go to bed at night, we are surrounded by various technological products that make our life easier and more convenient. Smartphones are one of the most important technological products in our life. With a smartphone, we can make phone calls, send messages, browse the Internet, shop online, watch videos and even work. We don’t need to carry cash with us; we can pay for goods and services through mobile payment apps, such as Alipay and WeChat Pay. This not only saves time but also makes our life more convenient. The Internet is another great invention of modern technology. It connects people all over the world together. We can use the Internet to get all kinds of information, learn new knowledge, communicate with friends and relatives far away, and even attend online classes. During the pandemic, online classes helped many students continue their studies without going to school. In addition, technology has also made great progress in the field of transportation. High-speed trains, electric cars and shared bikes have changed the way we travel. High-speed trains are fast and comfortable, which allow us to travel from one city to another in a short time. Electric cars are environmentally friendly, which help reduce air pollution. Shared bikes are convenient for short-distance travel and help us keep fit. Although technology brings many benefits to our life, we should also use it properly. We should not be addicted to smartphones or the Internet, and we should protect our personal information. Only in this way can we enjoy the convenience brought by technology and live a better life. 6. What is the main idea of this passage? A. The development of traditional culture. B.

C Different countries and regions have different social cultures, which are formed by long-term historical development and geographical environment. Understanding different social cultures is very important for us to communicate with people from different countries and promote cultural exchange. In Western countries, such as the United States and Britain, people pay great attention to individualism. They emphasize personal freedom and independence, and they like to express their own opinions directly. When communicating with others, they usually speak frankly and avoid being too polite or indirect. For example, if they don’t agree with something, they will say it directly instead of hiding their feelings. In contrast, people in Eastern countries, such as China and Japan, pay more attention to collectivism. They emphasize the importance of the group and family, and they are more polite and indirect when communicating. They usually consider the feelings of others first and avoid saying things that may make others uncomfortable. For example, when they refuse others’ requests, they will express it politely instead of saying “no” directly. There are also great differences in etiquette between different cultures. In some countries, shaking hands is a common greeting, while in other countries, people greet each other by bowing or kissing. For example, in Japan, people usually bow to greet each other, and the depth of the bow shows the degree of respect. In France, people often kiss on the cheek when they meet friends or relatives. With the development of globalization, cultural exchange between different countries is becoming more and more frequent. We should respect different social cultures, learn from each other’s advantages, and avoid cultural misunderstandings. Only in this way can we build a harmonious world with different cultures coexisting. 11. What is the main factor that forms different social cultures? A. Short-term social changes. B. Long-term historical development and geographical environment. C. People’s different hobbies. D. The size of the country. 12. What do people in Western countries pay great attention to? A.

Kissing on the cheek. C. Bowing. D. Hugging. 15. What should we do with different social cultures? A. Respect them, learn from each other and avoid misunderstandings. B. Reject them and stick to our own culture. C. Change other cultures into our own. D. Ignore them and do whatever we want. D In recent years, artificial intelligence (AI) has become one of the most popular topics in the field of science and technology. AI refers to the ability of computers to simulate human intelligence, such as learning, reasoning, and problem-solving. It has been widely used in various fields and is changing our life and work in many ways. AI is widely used in the medical field. For example, AI can help doctors diagnose diseases more accurately and quickly. It can analyze a large number of medical data, such as X-rays, CT scans and blood test results, and find out the possible diseases of patients. This not only saves time for doctors but also improves the accuracy of diagnosis, which is very helpful for the treatment of patients. In the field of education, AI also plays an important role. AI-powered teaching tools can provide personalized learning for students. According to students’ learning progress and strengths and weaknesses, AI can make personalized learning plans for each student. It can also answer students’ questions at any time, which helps students solve problems in study in a timely manner. In addition, AI can also help teachers grade homework and test papers, which reduces teachers’ workload. AI is also used in the field of smart home. Smart home devices, such as smart lights, smart air conditioners and smart speakers, are all powered by AI. We can control these devices through voice commands or mobile apps. For example, we can say “turn on the lights” to a smart speaker, and it will turn on the lights automatically. This makes our home life more convenient and comfortable. Although AI brings many benefits to us, it also brings some challenges. For example, it may lead to the loss of some jobs, because some repetitive work can be done by AI instead of humans. In addition, there are also some ethical and safety issues related to AI. We need to take measures to solve these problems and ensure that AI develops in a positive and healthy way. 16. What is AI? A. A kind of new computer. B. The ability of computers to simulate human intelligence. C. A kind of medical device. D. A smart home device. 17. How is AI used in the medical field? A. It can help doctors diagnose diseases more accurately and quickly. B. It can perform operations on patients. C. It can replace doctors completely. D. It can make medicine for patients. 18.
