With over 20 types, Tangchang cloth shoes are strong, soft, breathable and friendly to the environment. In 2018, they were added to Sichuan’s intangible cultural heritage list (非物质文化遗产名录). 63-year-old Lai Shufang has been making Tangchang cloth shoes for 40 years. Now she is very experienced. She said there are 32 steps to make a pair, but the most important step is making the soles. Layers (层) of white cloth are glued together with flour paste (糨糊). “To make good paste, we make it at a temperature of 85℃. If it’s too low or too high, the paste will not work.” Lai said. Then the pasted layers are dried and cut into different shapes. After this, they beat the layered cloth again and again until it is tight (紧实的) enough to make soles and upper parts. The next step is to shape the two parts and put them together. But still the soles edges look fluffy. Through repeated polishing and trimming (滚压和修整), the fluffy edges (毛边) will become smooth. Then the cloth shoes are ready. Lai’s hard work touched her son Ai Peng. In 2015, Ai decided to leave his job and help to make the cloth shoes more popular. He used Shu embroidery (蜀绣) to make the shoes look more beautiful and opened a cloth shoe store online. He also set up shop windows to show the steps of making shoes. 24. What is the most important step in making Tangchang cloth shoes according to Ms. Lai? A. Making the soles. B. Making the upper parts. C. Making good flour paste. D. Making smooth edges. 25. What is the correct order of the following steps in making Tangchang cloth shoes? ①beating the layered cloth ②making flour paste at the temperature of 85℃ ③putting the upper parts and the soles together A. ③②① B. ②③① C. ③①② D. ②①③ 26. According to the passage, how many things has Lai’s son done to make the cloth shoes more popular after he left his job? A. Two. B. Three. C. Four. D. Five. 27. What is the best title for this passage? A. A Talented Shoemaker, Lai Shufang B. Handmade cloth Shoes in Tangchang C. Tangchang, a Well-known Town in Chengdu D. Ai Peng’s cloth shoe Store C He is an old man who fishes alone (独自地) in a boat and he goes eighty-four days now without taking a fish. In the first forty days, a boy is with him. But after forty days without a fish, the boy’s parents tell him that the old man is unlucky, and the boy has to listen to his parents and stays in another boat which catches three good fish the first week. It makes the boy sad to see the old man come in each day with his boat empty (空的) and he always goes down to help him carry fishing tools. The old man is thin with deep wrinkles (皱纹) in the back of his neck. His hands have the deep scars (伤疤) from fighting with heavy fish. Everything about him is old except (除了) his eyes and they are the same color as the sea and the light in his eyes is like the dancing waves (浪花). “Santiago,” the boy says to him as they climb from the bank (河岸). “I can go with you again. We’ve made some money.” The old man teaches the boy to fish before and the boy loves him. “No.” the old man says. “You’re with a lucky boat. Stay in it.” “But remember how you go eighty-seven days without fish and then we catch big ones every day for three weeks.” “I remember,” the old man says. “It is papa who makes me leave. I am a boy and I must do what he tells me.” “I know.” the old man says, “I quite understand that.” “He doesn’t have much faith (信念).” “No.” the old man says, “But we do. Do we? I never think about giving up.” “Yes.” the boy says. “Can I give you a beer and then we’ll take the fishing tools home.” “Why not?” the old man says, “Between fishermen.” They sit on the bank and many of the fishermen make fun of the old man and he is not angry. Some other older fishermen look at him and are sad. But they don’t show it and they speak politely about the sea, the weather and of what they have seen. —Adopted from The Old Man and the Sea 28. The boy stops fishing with the old man because________. A. his parents believe the old man is unlucky B. the old man asks him to leave C. the boy wants to fish alone D. the old man’s boat is broken 29.

As the waves take away his anger (愤怒), he knows it is time to make peace with nature. C. He secretly follows the boy’s new boat and hopes to find fishing secrets to catch more fish. D. He sails out (出海) again for the eighty-fifth day with his eyes shining bright like the sea. D ①Have you ever thought about what ancient (古代的) people would say today? Did you hear them say things like “Look in my eyes! Tell me why?” 李时珍 (1518-1593) 明代医药学家 ②These days, some creative vloggers (视频博主) are using AI to bring famous people from history “back to life”. In their videos, these people speak in modern ways with funny faces. For example, Ming Dynasty medical expert Li Shizhen laughs at modern ways of life, like trying to be healthy by drinking goji berry (枸杞) water but still going to bed late. ③“I didn’t know much about the stories of these ancient people before. The videos let me learn more about them.” said Wang Jiayi, 15. ④These videos also make people more excited to learn about history. Zhang Xu from Guangdong shared his ideas, “I wasn’t interested in history before, but now I even go to the library to read history books.” ⑤However, not everyone enjoys the videos. Some people feel unhappy because of the way these ancient people speak—high tones (声调) and always asking questions. “They’re too pushy (压迫感的), which is different from how they really were,” said 14-year-old Wang Shuotong. ⑥Xiao Boen, 14, felt the same. But he agreed that this special way helped him remember almost everything they said. ⑦These videos let ancient people speak for themselves. However, “We should be careful with these videos, and make sure they don’t share fake (虚假) information,” said Nanfang Daily. 32. How does the writer start the passage? A. By telling stories. B. By giving numbers. C. By asking questions. D. By giving reasons. 33. Which of the following may Li Shizhen laugh at? A. Exercising and eating much fast food. B. Early to bed and early to rise. C. Eating fruit and drinking hot water. D. First to arrive and last to leave. 34. Which picture shows the sides (立场) of the four persons correctly? A. B. C. D. 35. Which is the right structure of the passage? A. B. C. D. Ⅴ.口语应用。（每小题2分。共10分） 阅读下面对话，从下面7个选项中选择5个恰当的句子完成此对话。 A: Hi, Sarah! How was your school trip last weekend? B: Hi, Steve!

Let me introduce (介绍) three of them—the turtle, the deer, and the crane. The Long-Lived Turtle Turtles are slow-moving reptiles (爬行动物) with hard shells (壳). They usually live in rivers lakes, and oceans. In China, turtles are a symbol of long life because they can live for many years. In ancient times, some Chinese people used turtle shells to predict (预测) what would happen in the future. Turtles also show stability—they carry their shell homes everywhere they go. The Pure Crane Cranes are tall birds with long legs and necks. They live near water. In the eyes of Chinese, their white feathers mean purity (纯洁). Also, in old Chinese stories, people believed cranes were magical—they would carry kind and wise people to heaven (天堂). When artists paint pine trees, they like to draw a crane next to them. This shows the hope for a happy life. The Lucky Deer Deer are shy, fast animals with branched antlers (角). They always live in forests and grasslands. In Chinese culture, deer mean good luck and success because the Chinese word for deer (鹿“lù”) sounds like the word for money and success (禄“lù”). Long ago, Chinese emperors loved to hunt deer to show their power. 41. Did people in ancient times use turtle shells to predict the future? _______________________________________________________________________________________________ 42. Why do deer mean good luck and success in Chinese culture? _______________________________________________________________________________________________ 43. From what aspects (方面) does the writer introduce the three animals? _______________________________________________________________________________________________ 44.

Ⅷ.概要补全。（1和4小题，每小题2分；2和3小题，每小题3分；共10分） 阅读文章，用恰当的词块或句子补全概要。 Many people believe in the “five-second rule”—if you pick up dropped food within five seconds, it’s safe to eat. But is this true? Experts don’t think so. Schaffner, a food science professor, explains that bacteria (细菌) can move to food right away. “Bacteria don’t have legs. They move with the liquid (液体). The more liquid in the food, the more easily it gets bacteria, ” Schaffner says. For example, if a piece of watermelon falls on the floor, it might collect bacteria quickly. Even if you pick it up quickly, it could still be dangerous to eat. Many people think that food dropped on a carpeted (铺有地毯的) floor is very dirty. However, another expert, Professor Hilton, found that carpeted floors pass on fewer bacteria than hard surfaces (表面) like wood. This is because the top of a carpet keeps food away from bacteria that lie closer to the ground. Still, he warns people to be careful. Food on the floor can never be completely safe. But what if your food is dropped on the kitchen counter instead of the floor? Dr. Dowshen, advises not eating such food as well. Raw (生的) meat or other foods can leave bad bacteria called salmonella (沙门氏菌) on the top. Food from a dirty counter could make you sick. In the end, you can never be too careful about what you put in your mouth. When you’re not sure, it’s probably better to just throw it away. Many people believe dropped food is safe if they pick it up within five seconds, but experts say ____50____. Bacteria can move to food quickly, especially (尤其是) ____51____ like watermelon. Surprisingly, food dropped on carpet might pick up fewer bacteria than on hard floors like wood, but food on the floor ____52____. Food dropped on kitchen counters is also not safe. The advice is clear: when food touches the floor or a dirty counter, ____53____. Better safe than sorry!
