But now there’s a new way of travelling in China: industrial tourism. This means visiting factories during holidays, not just relaxing or spending money. Hu Si tried it during the May Day holiday in 2026. She and her friends visited a rice wine (酒) factory. They watched how to make huangjiu and tasted special drinks like huangjiu-flavoured (有……味道的) milk tea. She said it was a new experience to learn something while travelling. Industrial tourism started in Europe around the 1950s and came to China in the 1990s. Now, it is becoming favoured there. Over 1,000 industrial tourist places are in China now. For example, the Tsingtao Beer Museum (青岛啤酒博物馆) had 1.8 million tourists in 2025. Why do people love it? Because it’s fun! You can do many activities in the factories, like making cakes, watching robots build cars, or enjoying 3D shows. These make trips exciting. Also, this kind of trips help build trust (信任) between factories and customers. If people see how the workers make products, they will trust the products more. 19.

C “Time to get up!” I don’t want to get up. It isn’t time to get up. “Come on, get out of bed,” says Dad. “I need your sheets (床单).” Oh, right. It’s Saturday, Laundry (洗衣物) Day. Dad has a new idea. He washes clothes and sheets by hand, especially in summer. Then I have to hang all of them on the rope in the yard. It seems like a lot of work. And it means I can’t get up late on Saturday. Dad gets the washing started early. That way all the clothes can be dry by the end of the day. “Up,” says Dad as he starts taking the sheets off the bed. I drop off the bed onto the floor. “Go and hang this!” Dad drops a wet sheet on me. It’s so cold! After I hang up the sheet, I come inside and find Dad in the kitchen. Dad sits down across from me after making some biscuits. “Why so angry? You know we have to do the laundry, right? And do you realize that I collect the laundry, wash it, take it off the rope and put it away?” I am starting to feel guilty, with my face red. “And you have to help out around here, right?” “I know, Dad. I also know that by hanging the clothes instead of using machines, we can save more energy.” Dad is glad that I remember all that. I’m quiet for a minute. I think I have to stop complaining (抱怨) about hanging the rest of the clothes. 23. Why does Dad wash the clothes early? A. Because Dad wants the son to help. B. Because Dad has to work after washing. C. Because Dad has so many clothes to wash. D. Because the clothes can be dry by the end of the day. 24. Which of the following blanks can we use the underlined word “guilty” to fill in? A. The dog was ________ when its mother came after a long day. B. Mary was ________ when she saw a big cake waiting for her on her birthday. C. The boy felt ________ when his friend couldn’t help him with the homework. D. Sarah felt ________ for lying to her friend, as she knew that she hurt her feelings. 25.
