When I was 2 months old, one day while I was playing with my owner in the park, a policeman saw me and thought I had the talent to be a police dog. Then, I started my training. Every day, I take classes. I learn many cool things like how to listen well, control myself well, and find dangerous things. My short legs make me stand out! I can get into and search small spaces easily. Big dogs can’t do this but I can! My only problem is that I can’t run very fast because of my short legs.

It seems that no one here expects foreigners to be able to eat spicy food, let alone enjoy it.But in fact, we have a long tradition of eating spicy food in the US. I guess I could start with Tex-Mex food. Tex-Mex brings food with both Mexican and American styles. It is very popular in Texas and other southwestern US states. It uses a lot of cheese, Texas-style chili con carne (a mix of meat, beans and hot peppers) and flour tortillas (玉米薄饼). Tex-Mex can be quite spicy. Also, the US is home to many “chiliheads” who are known for their love of hot chill peppers. Chiliheads like to collect and eat spicy peppers.The hottest chili pepper in the world is Carolina Reaper. It is grown in the US state of South Carolina. When you start to eat it, spicy food in the US feels different from that of ChinA. Spicy dishes in the US have what we call a “slow burn”-they don’t sting (刺痛) your mouth right away, but slowly become hotter as you eat more. On the other hand, spicy Chinese food like Chongqing hotpot can be very spicy as soon as you start to eat it. Food like huajiao can cause a numbing (麻木的) feeling in the mouth. It’s very special. 28. What do you know about Tex-Mex food? A. It is real Mexican food. B. It has a lot of cheese and is quite spicy. C. It is popular in South America. D. It is a mix of Mexican and Canadian food. 29. What does the underline word “chiliheads” refer to? A. People who like spicy food. B. People who live in the US. C. The South Carolina farmers. D. People who grow Carolina Reaper. 30. According to the writer, which of the following is true? A. Spicy food in China may make your lips hurt. B. Spicy food in the US can cause a numbing feeling. C. Spicy food in China never stings your mouth right away. D. Spicy food in the US may become hotter as you eat more. 31. What can we learn from the passage? A. The writer is from America. B. Most people in America love spicy food. C. Huajiao is a very spicy food. D. The US and China’s spicy foods are similar. 【答案】28. B 29. A 30. D 31. A 【解析】 【导语】本文是一篇说明文。主要讨论了了美国和中国的辣食文化。 【28题详解】 细节理解题。根据“It uses a lot of cheese, Texas-style chili con carne (a mix of meat, beans and hot peppers) and flour tortillas (玉米薄饼).Tex-Mex can be quite spicy.”可知，德克萨斯墨西哥风格的食物有很多奶酪，而且很辣。故选B。 【29题详解】 词句猜测题。根据“Also, the US is home to many “chiliheads” who are known for their love of hot chill peppers.”可知，chiliheads以喜欢辣椒而闻名，因此可推测chiliheads意为“喜欢吃辣的人”。故选A。 【30题详解】 细节理解题。根据“Spicy dishes in the US have what we call a “slow burn”-they don’t sting (刺痛) your mouth right away, but slowly become hotter as you eat more.”可知，美国的辣菜有一个被称为“缓慢燃烧”的特点——它们不会立刻刺激你的口腔，而是随着你吃的越多越变得辣。选项D“在美国，辛辣食物可能会越吃越辣”符合原文。故选D。 【31题详解】 细节理解题。根据“But in fact, we have a long tradition of eating spicy food in the US.”可知，我们在美国有吃辣的悠久传统，因此作者来自美国。选项A“作者来自美国”符合原文。故选A。 D After learning about the life of the great poet who lived about 1, 300 years ago in the historical documentary (纪录片) Li Bai on CCTV-9, many young Chinese have preferred talking about going after their dreams on the Internet. “If Du Fu is the greatest poet in China, then Li Bai is the most talented poet in the history of Chinese poetry,” an expert in ancient Chinese literature told the Global Times.

Now, the aircraft has an official permit (官方许可证) to fly people without a pilot. ③EH216-S can carry two people. It can fly 130 kilometers every hour. This is much faster than taxis on the road. And it can take off from and land at any flat (平坦的) place, such as the top of a building or the square in a park. ④To make the passengers safe, new technologies are used in the aircraft. ⑤The aircraft has 16 propellers (螺旋桨). If some of them break, others can still work to make the aircraft fly safely. ⑥It can check its “health” by itself. For example, if a bird hits into it, it will find out whether it should go on flying or land at a safe place near there. ⑦AI helps set a few routes (线路) before flying. If there is something happening on one route, the aircraft will choose another. ⑧Of course, the aircraft must go through full safety and technological tests before it can truly be used. And the government must make rules to better manage (管理) the fast-developing sector (行业). 36. Where can the aircraft land according to the passage? A. In the woods in the park. B.

For example, if a bird hits into it, it will find out whether it should go on flying or land at a safe place near there.”可知，电动飞行器EH2l6-S可以自己检查自己的“健康状况”，例如，如果一只鸟撞到了它，它会判断是否应该继续飞行还是在附近找到一个安全的地方降落，因此作者是通过举例子来开展他在第6段中的观点的。故选B。 【38题详解】 推理判断题。根据“Of course, the aircraft must go through full safety and technological tests before it can truly be used. And the government must make rules to better manage (管理) the fast-developing sector (行业).”可知，飞机必须经过全面的安全和技术测试才能真正使用，政府必须制定规则，更好地管理快速发展的行业，因此可推知，作者写最后一段的目的是就如何管理快速发展的行业提供建议。故选A。 【39题详解】 篇章结构题。根据全文可知，文章第①②段引出电动飞行器EH2l6-S这一话题；第③段简单介绍电动飞行器EH2l6-S；第④⑤⑥⑦介绍电动飞行器EH2l6-S使用的新技术；第⑧段为如何管理电动飞行器行业快速发展提供建议。故选B。 V.口语应用。 阅读下面对话，从文后7个选项中选择5个恰当的选项完成此对话。 A: Hey, Bob.

A patent has the protection from the country. If others want to make money from it, they can only do this after the owner says yes, often with much pay. There are three usual kinds of patents: ●New technical solution (技术方案): It means something that is completely new. ●Utility (实用) model: It means some things with new uses. ●Design (外观设计): It’s about new designs of the shape, pattern (图案) or color. According to Xinhua, China has led the world with 4.05 million working patents by the end of 2023. It is the first country to pass 3 million. The number shows China’s work to encourage innovation (鼓励创新). With a little creativity, everyone can get a patent. Zhang Zehua, Wang Yanchen and Zhang Zhenjie are 3 students from Xi’an, Shaanxi province. They created a smart trash bin (垃圾箱) and got a patent. The trash bin uses voice recognition (语音识别). If you don’t know which kind of waste it is, don’t worry. Just speak to this trash bin and it will help you find out the answer quickly. The bin can even understand different Chinese dialects(方言). 45. Can people make money from a patent if the owner of the patent doesn’t agree with it? ________________________________________ 46.

China created 12.44 million new jobs in the city. ■The country’s sales of new energy cars (新能源汽车) took up more than 60% of the world’s China’s grain output (粮食产量) reached more than 695 million tons (吨). 21.

Some people think I can’t be a great police dog because of my short legs. But I’m here to show they are wrong! I used to be a pet dog. When I was 2 months old, one day while I was playing with my owner in the park, a policeman saw me and thought I had the talent to be a police dog. Then, I started my training. Every day, I take classes. I learn many cool things like how to listen well, control myself well, and find dangerous things. My short legs make me stand out! I can get into and search small spaces easily. Big dogs can’t do this but I can! My only problem is that I can’t run very fast because of my short legs. When we are outside doing our job, my trainer has to carry me on his back. But it’s one of my favorite parts of the job. 24. When did Fuzai begin to take the lessons of police dogs? A. When he was 2 years old. B. When he was 9 years old. C. When he was 2 months old. D. When he was 9 months old. 25. Why does Fuzai’s trainer often carry him on the back? A. Because Fuzai is young. B. Because Fuzai is lovely. C. Because Fuzai works hard. D. Because Fuzai can’t run fast. 26. What can’t big police dogs do? A. They can’t listen well. B. They can’t search small spaces. C. They can’t find dangerous things. D. They can’t control themselves well. 27. In which part of a magazine can you probably read this passage? A. Sports. B. Weather. C. Culture. D. Animals. C For some reason, Chinese people seem to be very surprised when I tell them I like spicy (辣的) food. It seems that no one here expects foreigners to be able to eat spicy food, let alone enjoy it.But in fact, we have a long tradition of eating spicy food in the US. I guess I could start with Tex-Mex food. Tex-Mex brings food with both Mexican and American styles. It is very popular in Texas and other southwestern US states. It uses a lot of cheese, Texas-style chili con carne (a mix of meat, beans and hot peppers) and flour tortillas (玉米薄饼). Tex-Mex can be quite spicy. Also, the US is home to many “chiliheads” who are known for their love of hot chill peppers. Chiliheads like to collect and eat spicy peppers.The hottest chili pepper in the world is Carolina Reaper. It is grown in the US state of South Carolina. When you start to eat it, spicy food in the US feels different from that of ChinA. Spicy dishes in the US have what we call a “slow burn”-they don’t sting (刺痛) your mouth right away, but slowly become hotter as you eat more. On the other hand, spicy Chinese food like Chongqing hotpot can be very spicy as soon as you start to eat it. Food like huajiao can cause a numbing (麻木的) feeling in the mouth. It’s very special. 28. What do you know about Tex-Mex food? A. It is real Mexican food. B. It has a lot of cheese and is quite spicy. C. It is popular in South America. D. It is a mix of Mexican and Canadian food. 29. What does the underline word “chiliheads” refer to? A. People who like spicy food. B. People who live in the US. C. The South Carolina farmers. D. People who grow Carolina Reaper. 30. According to the writer, which of the following is true? A. Spicy food in China may make your lips hurt. B. Spicy food in the US can cause a numbing feeling. C. Spicy food in China never stings your mouth right away. D. Spicy food in the US may become hotter as you eat more. 31. What can we learn from the passage? A. The writer is from America. B. Most people in America love spicy food. C. Huajiao is a very spicy food. D. The US and China’s spicy foods are similar. D After learning about the life of the great poet who lived about 1, 300 years ago in the historical documentary (纪录片) Li Bai on CCTV-9, many young Chinese have preferred talking about going after their dreams on the Internet. “If Du Fu is the greatest poet in China, then Li Bai is the most talented poet in the history of Chinese poetry,” an expert in ancient Chinese literature told the Global Times. Much of Li’s life is described in his poems: his love heroism, and freedom while traveling around the mountains and rivers of China, and his hard life experiences. He saw the Tang Dynasty’s amazing success, and dreamed about being an excellent officer to serve the court (朝廷), but experienced challenge after challenge until his death. Li Bai has won great love among Chinese netizens (网民). The story of the poet’s life has got many young Chinese’s interest. ▲ When talking about “What would we do if our dreams couldn’t be reached, just like Li’s?”, some netizens said that they might change to another dream in order not to give themselves too much pressure or unhappiness, while other netizens said they would choose to “hold on straight to the end”. “In fact, many people who like Li Bai’s poems like the spirit he showed—the spirit of never giving up and dreaming about doing something good to help society, just like many young people who have the same dream now,” an expert in ancient Chinese literature said. 32. In the second paragraph (段落), what did the expert think of Li Bai? A. The greatest poet. B. A famous traveler. C. An excellent officer. D. The most talented poet. 33. Which of the following can be put into the ▲ ? A. Many young people try to achieve their dreams. B Young netizens have different ideas about Li’s life. C. Many young people are interested in Chinese history. D. Ancient Chinese poets encourage young people to challenge life. 34. Why do many people like Li Bai’s poems according to the last paragraph? a. Because of his ability of writing poems. b. Because of his wishes for working for society. c. Because of his doing well in serving the court. d. Because of his spirit of keeping trying to do something. A. ab B. ac C. bd D. cd 35. What does the article mainly talk about? A. The life experiences of Du Fu and Li Bai. B. The poems and spirit of Li Bai and Du Fu. C. The historical documentary Li Bai on CCTV-9. D. Li Bai’s spirit and importance in Chinese literary. E ①Early in the morning, everybody is in a hurry, but the roads are very busy. Can we take an air taxi to go from one place to another? ②The Chinese company EHang says that this may not be very far away. Its EH216-S is an electrical aircraft (电动飞行器). Now, the aircraft has an official permit (官方许可证) to fly people without a pilot. ③EH216-S can carry two people. It can fly 130 kilometers every hour. This is much faster than taxis on the road. And it can take off from and land at any flat (平坦的) place, such as the top of a building or the square in a park. ④To make the passengers safe, new technologies are used in the aircraft. ⑤The aircraft has 16 propellers (螺旋桨). If some of them break, others can still work to make the aircraft fly safely. ⑥It can check its “health” by itself. For example, if a bird hits into it, it will find out whether it should go on flying or land at a safe place near there. ⑦AI helps set a few routes (线路) before flying. If there is something happening on one route, the aircraft will choose another. ⑧Of course, the aircraft must go through full safety and technological tests before it can truly be used. And the government must make rules to better manage (管理) the fast-developing sector (行业). 36. Where can the aircraft land according to the passage? A. In the woods in the park. B. On the river near the city. C. On the playground of a school. D. On the stairs (楼梯) in a building. 37. How does the writer develop his idea in Paragraph 6? A. By telling a story. B. By giving an example. C. By comparing differences. D. By listing numbers. 38. What’s the purpose (目的) of writing the last paragraph? A. To give advice on how to manage fast-developing sectors. B. To wonder when people can truly use the aircraft in their lives. C. To ask the company and the government to make sure of the safety. D. To show the tests the company will do before the aircraft is truly used. 39. Which of the following shows the structure of this passage? A. B. C. D.
