It has a history of several hundred years. In 2005, the Culture and Art Center of Jiangxi Opera was set up at Nanchang University for this local opera. From then on, a course named Appreciation of the Jiangxi Opera (《赣剧鉴赏》) has been taught at Nanchang University in Jiangxi Province. Chen Li, the teacher, shows how great Jiangxi Opera is by wearing traditional make-up (妆容) and costumes, and doing moves like waving water sleeves (甩水袖) and spinning (旋转) folding fans. “I used to give students speeches about Jiangxi Opera without performing. So in the classroom, you might find students who weren't interested in them slept in my class or even played on their phones in class,” said Chen. To make her class more interesting, Chen decided to wear costumes and turn the course into a stage to perform. This made students more interested in Jiangxi Opera. Recently, many of the students have recorded the performances and posted the videos of the course on the Internet. They have caught tons of attention and many people like them. Now, Chen’s class is always full of students, especially after a report about her course on March 23rd, 2024. Ms. Chen didn’t expect to be so successful. She has been satisfied with the result, and she has also realized that there will be a greater responsibility for her. “I hope that even though people will be less interested in Jiangxi Opera in the future, this art can still be passed down with our efforts,” Chen said. 38. How long has the Culture and Art Center of Jiangxi Opera been at Nanchang University? A. For less than twenty years. B. For just a few days. C. For less than two months. D. For several hundred years. 39. What did Ms. Chen use to do in her class? A. She used to teach students how to make up. B. She used to show students how to wave water sleeves. C.

It’s because we’re studying sleep cycles(周期) according to World Sleep Day which was celebrated on March 21. Our bodies sleep in 90-minute cycles, experiencing five to six each night. At first, you enter a light stage of sleep when your muscles (肌肉) relax. Then, the body temperature drops, and the heart rate (心率) slows. Next comes deep sleep. It’s difficult to wake up during this stage. At this time, your body repairs itself and builds up energy for the day ahead. Finally, you get into the rapid eye movement (REM，快速眼动) sleep stage. It is when most dreaming happens. After REM sleep, the cycle repeats. Waking up in the morning in the “wrong” stage can make you feel especially tired. An app called Sleep Calculator (计算器) can help you avoid this. It’s a tool designed to work out the perfect bedtime for you based on your wake-up time. Developed by the UK company Hillarys, this smart calculator considers the sleep cycles that our bodies go through each night. Whether you’re an early bird or a night owl, simply input your wake-up time, and the calculator will work its magic, suggesting the perfect bedtime to make sure that you rise and shine with a spring in your step. It’s necessary to know that you shouldn’t just start your sleep cycle whenever you want. Many young people go to bed late and get up late, such as sleeping from 2 a.m. to 10 a.m. They think as long as they have 8 hours of sleep, everything will be fine. But in fact, our bodies can tell the time, particularly by using light and temperature. If we wake up too late, we may feel a bit like a zombie (僵尸). That’s why sometimes we feel even more tired after oversleeping. 48. How many steps does our body go through in one sleep cycle? A. Two. B. Three. C. Five. D. Six. 49. What can this sleep calculator do for us? A. It can work out the perfect bedtime. B. It can record the total time of sleep. C. It can make you wake up early. D. It can help you fall asleep earlier. 50. What can we probably infer from the last paragraph? A. All we need is eight hours of sleep. B. With a sleep calculator, we can sleep well. C. Sometimes the more you sleep, the more tired you get. D. We can tell the time and calculate the reasonable sleep time. 51. Which of the following best shows the structure of the passage? A. ①/②/③④⑤/⑥ B. ①/②③④⑤/⑥ C. ①②③④⑤/⑥ D. ①/②/③④/⑤⑥ 52. Which of the following can be the best title? A. World Sleep Day Celebration B. Getting Your Sleep Cycle Right C. The Invention of Sleep Calculator D. How to Make the Body Healthier B）（每小题2分） 请先阅读下面短文，掌握其大意，然后根据短文内容从下面的七个选项中选择五个还原到文中，使短文意思通顺、结构完整，并将其填到答题卷的相应位置。 Younger Chinese citizens have developed new ways to reduce stress, such as raising special “pets” or hugging trees. ____53____ It can bring a sense of calmness, according to Internet users.
