B When you graduate (毕业) from the university, do you prefer to work in a big company or grow strawberries in your hometown? Wang He, a girl who studied art and design, chose to become a strawberry farmer after graduating. When she was at university, Wang He always spent her free time helping her grandmother to sell strawberries. She noticed that Changfeng strawberries were more popular than others, because they were juicy (多汁的) and very sweet. However, she also realized that they didn’t have a special local brand (品牌) to make them famous. This made Wang want to make a special local brand of strawberries. She wanted to make Changfeng strawberries famous not just at her hometown, but possibly around the world. After graduating in 2022, Wang went back to her hometown and became a “new farmer”. To plant juicy and sweet strawberries. Wang worked hard in the field and greenhouse. She met many kinds of difficulties, but she didn’t give up. Once, she fell down in the field and hurt her legs badly. However, she didn’t tell her family about it. She just treated her wounds secretly. Now, her strawberries are ready for sale. Even though she is very busy, she still spends time packing them beautifully. She uses gift boxes and prints pretty designs on the outside. Her artistic skills make the whole process of growing and selling strawberries more special. Taking root in countryside has made her career a success. And Wang also helped the villagers become rich and promote rural revitalization (乡村振兴). In a word, there are many different roads to reach success. 39. What did Wang He want to do with the Changfeng strawberries? A. Grow them all year round. B. Use them to make strawberry juice. C. Make a special local brand for them. D. Help the villagers live in the city. 40. What does the underlined word “it” in Paragraph 3 refer to (指的是)? A. The decision to become a strawberry farmer. B. The fact about hurting her legs badly. C. The idea of creating a new strawberry brand. D. The difficulties she meets in the field and greenhouse. 41. Which of the following best describes Wang He? A. Strict and caring. B. Patient and outgoing. C. Creative and hard-working. D. Friendly and understanding 42. Which of the following is the best title (标题) for the text? A. All roads lead to Rome. B.

After using it, he is able to take some small steps with others’ help. A woman had trouble speaking. When she thinks of words in her mind, Beinao-1 turns her thoughts into text on a screen. Now she can “talk” to her family again. Beinao-1 is a breakthrough (突破) that Chinese scientists have made. With it, they have successfully helped several disabled people start to move and speak again, giving them a new chance at life. Beinao-1 uses a thin and soft electrode sheet. It can fit the brain comfortably. When it is put on the brain’s surface, it receives signals and sends them out. There’s also a small wireless device (无线设备) that can receive and translate the signals for a smart machine. With this “translator”, the machine can understand the thoughts from the brain and act. For example, if a disabled person thinks “I want to drink water”, a robotic arm can pick up a cup, fill it with water, lift it carefully to the person’s mouth, and finally put it back. In this way, Beinao-1 helps disabled people control things by thoughts. Beinao-1 is China’s completely self-developed technology. It has broken the world record in its field. It shows that China has become more powerful in high technology. We believe China will continue to lead the world in technology development. 43. How does Beinao-1 help the woman in paragraph 2? A. By talking to a robot. B. By writing letters to her family. C. By turning her thoughts into text. D. By sending signals to other people. 44. What does the underlined word “translator” in Paragraph 4 mean? A. A person who translates languages. B. A robotic arm that helps with actions. C. A screen that shows text from brain to people. D. A device that changes brain signals for machines. 45. What does the writer think of Beinao-1? A. Unclear. B. Hopeful. C. Uninterested. D. Negative. D “May we all be blessed with longevity. Though miles apart, we are still able to share the beauty of the moon together.” wrote Su Shi, a poet during the Song Dynasty, in his well-known poem to his younger brother Su Zhe. The moon is at its brightest on the 15th day of the eighth month of the lunar calendar. On this day, people celebrate Mid-Autumn Festival. It has been enjoying great popularity all over the country. In ancient China, that day was a harvest (收获) festival because crops were harvested during that period. It was a time for relaxation and celebration. Just like Thanksgiving in Western countries, families also try to get together for the Mid-Autumn Festival in China. Usually, no matter how far away or how busy they are, people will try to return home for the celebration. The full moon and moon cakes stand for family reunion. With the beautiful moon up in the sky, people sit together, enjoy the full moon, eat moon cakes and fruit, share the stories, and express the best wishes for the family members and friends who live far. 46.

By 2021, more than 400 million adults were too heavy. According to a study in a medical magazine, this number will rise to 630 million by 2050. Being heavy can be harmful to our health. It causes many diseases. Big cities, like Beijing and Shanghai have already started the fight against obesity. They use safe ways to help people lose weight. These include healthy diets and traditional Chinese medicine. At the same time, people in the countryside also need help because obesity has been on the rise since 2005 in town and country areas. We can see many ways to lose weight in social media. However, they can be dangerous. So China is now making medicine to help control weight safely. The government is calling for the support of hotels, schools and businesses. For example, schools are teaching students about healthy eating. In some cities, junk food isn’t allowed to be sold at or near schools. 49. According to the study, what will the number of overweight adults in China be by 2050? A. About 400 million. B.

The number of overweight people will fall down soon. F The Palace Museum, also known as the Forbidden City, is located in the heart of Beijing. It was the Chinese imperial (皇家的) palace from the Ming dynasty to the end of the Qing dynasty. For almost 500 years, it served as the home of emperors and the political center of ancient China. The Palace Museum is one of the largest and best-preserved ancient wooden structures in the world. It covers an area of about 72 hectares (公顷) and has over 9000 rooms! The buildings are painted in brilliant red and yellow, colors that symbolized power and royalty in ancient China. The roofs, with their golden tiles and beautiful animal statues, seem to touch the sky. Walking through its grand courtyards is like stepping back into a different era. Today, the Palace Museum is no longer an imperial palace but a world-famous museum. It houses a priceless collection of over 1.8 million cultural relics, including paintings, ceramics, and historical documents. Every year, it attracts millions of visitors from home and abroad.
