She teaches Chinese, but she is very interested in computer technology. She has introduced coding(编程) to her students as an important information technology skill. Chen's connection to coding began in November 2020. She became one of the first teachers in Cangyuan to take training courses on coding. The training was challenging for a beginner like Chen. She needed to learn how to tell a machine to perform(执行) actions and finish tasks through different orders. She worked very hard because she believed this skill would be useful for her students. After the training, Chen started a new group in her school to teach the students coding, but some parents didn't agree with her plan. They didn't understand what coding was and thought Chen was teaching their children to play video games on the computer. So, Chen could only teach students of her own class at first. For teens, coding does not include writing difficult coding languages. Instead, Chen taught them how to create interesting cartoons and games. After only one term, every student was able to create something through coding. Learning coding also helped them become more creative and improved their problem-solving skills. Soon, coding classes became popular in schools all over Cangyuan. Some students even won prizes in a national competition last year. "I will work harder and I hope these children in mountain areas will have a better future by learning information technology," Chen said. ( )46. Why did Chen introduce coding to her students? A. Because it was easy to teach. B. Because it was a useful skill. C. Because it was popular to learn coding. D. Because it was a fun way to spend time. ( )47. What did Chen teach her students in the coding class? A. How to play video games on the computer. B. How to prepare for difficult coding languages. C. How to create interesting cartoons and games. D. How to use the internet to search for information. ( )48. What is the best title for the passage? A. Coding helps students think better B. A teacher brings coding to rural children C. Coding gets popular in China's schools D. A teacher connects coding with the Chinese language B Here is a story. A man sees a butterfly trying to get out of its chrysalis(蛹). Feeling sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out easily. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn't struggle(挣扎) to leave the chrysalis, it can't fly! The struggle develops the energy in the butterfly, which makes it fly. Similarly, the challenges of life bring out the best in young people and make them fly. When people are young, meeting and overcoming challenges will make them strong and ready to face life. When we look at successful people, we see that the most successful of them are people who have had to struggle. One famous businessman, who now owns many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. His father's death forced him to grow up fast. He had to bring up a family of nine people. He took up the challenges and overcame them. Today his brothers and sisters are leading successful lives. Sometimes challenges do not happen to us because we keep away from them. So some parents and teachers actively encourage young people to face challenges. They might organize some activities for young people, which provide them with challenges, like rock climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of tomorrow. For countries to continue to become successful, it is important that the young people learn to meet challenges and overcome them. ( )49. From the story we know that the butterfly can't fly because . A. it gets out by itself B. the man feels sorry for it C. it tries to challenge itself D. the man helps it come out ( )50. According to the passage, we know that . A. challenges always happen to everyone B. passing exams doesn't belong to challenges C. rock climbing and camping are helpful challenges D. it's unnecessary for young people to do volunteer work ( )51. What is the best title for this passage? A. Successful People Have a Sense of Achievement B. Young People Must Develop Their Energy Actively C. Countries Should Continue to Become Successful D. Challenges of Life Bring Out the Best in Young People C Lightning usually destroys(破坏) trees it hits. But scientists have found an amazing tree. It not only lives through lightning strikes(击中) but actually grows better because of them! For years, scientists thought lightning was only bad for trees. But as they explored places like the Amazon rainforest, they started to think there could be trees that fight against lightning. It wasn't until about 100 years ago that such "super trees" were discovered. Now, they know of a tree that uses lightning's power to kill nearby trees and get more sunlight and nutrients(营养物) for itself. In 2015, scientist Evan Gora saw a Dipteryx oleifera tree, which had been struck by strong lightning. It wasn't badly harmed while the neighbouring trees were killed. Scientists thought this tree could handle lightning, but there was no way to be sure. Gora and his team saw more of these trees that grew well after lightning strikes. So, they did a study. They followed 93 trees struck by lightning for 2—6 years. They found that all 9 Dipteryx oleifera trees in the study survived with little harm. But 84 other trees were badly hurt, and 64% of them died within two years. These Dipteryx oleifera trees are very tall and have wide tops, making them 68% more likely to be struck by lightning than other trees. During the study, one of the Dipteryx oleifera trees was struck twice in 5 years yet continued to grow well. At present, more studies suggest that these trees attract lightning on purpose to destroy other trees and grow better. Scientists are not sure how these trees survive lightning, but they guess it may involve the trees' ability to carry electricity. They are also interested in other trees with similar characteristics. ( )52. What is special about the Dipteryx oleifera tree? A. It dies quickly after lightning strikes. B. It takes in nutrients directly from lightning. C. It grows better after being struck by lightning. D. It avoids lightning by hiding under other trees. ( )53. What does the underlined word "handle" in Paragraph 1 mean? A. Mix up. B. Give out. C. Suffer from. D. Deal with. ( )54. Why do Dipteryx oleifera trees attract lightning on purpose? A. To get more water from the sky. B. To kill nearby trees for growth. C. To become shorter and stronger. D. To protect other trees around them. ( )55. What might scientists do next according to the text? A. Plant more Dipteryx oleifera trees. B. Study how trees attract lightning better. C. Find out where Dipteryx oleifera trees live. D. Look for more trees that can survive lightning. B)阅读短文,从A-F六个选项中选出五个可以填入空白项的最佳答案。 Emotional toughness(韧性) is the ability to stay strong and focused when people face challenges or criticism(批评). Many successful people, like Alexander Graham Bell and the Wright Brothers, had this quality. 56. Instead, it means standing up for your beliefs and setting clear boundaries(界限). To develop emotional toughness, we can follow these steps. One way is to learn who to trust. Emotionally tough people sometimes make mistakes in judging others but they learn from them and avoid repeating them. 57. By taking small actions outside your daily schedules, you can build confidence and prepare for bigger challenges. 58. Emotionally tough people stay healthy by exercising, sleeping well, and eating balanced meals. They stick to their routines even when they don't feel like it. Building positive relationships is the fourth key step. Emotionally tough people spend time with those who inspire and support them. 59. Finally, focus on your own goals instead of comparing yourself to others. Emotionally tough people set clear goals, celebrate their achievements, and keep moving forward. They don't waste time worrying about what others think. 60. It's a skill that can be developed through practice and good habits. By following these steps, we can become stronger and better prepared to face life's challenges. A. These relationships provide encouragement, especially during difficult times. B. Thirdly, self-discipline(自律) is also important. C. Another way is to try to step out of your comfort zone. D. It doesn't mean being rude or cold, or ignoring(忽视) others. E. They often compare themselves to others to measure their success. F. Emotional toughness is not something we are born with. 五、词汇运用(共5小题;每小题1分,满分5分) 选用方框内的单词或短语填空,其中有一个单词或短语是多余选项。 although, connected, encourage, praise, in all, thinking twice I used to be a fat kid.

Residents can rent a small piece of land in the garden to grow their own vegetables. This idea was created by a community committee in Pudong District to solve two problems: unused empty spaces and the need for green activities among city residents. Mrs Wang, a retired teacher, rents a 10-square-meter plot. "I come here every morning. It's like my morning exercise. I grow tomatoes, cucumbers, and leafy greens. They taste much better than those from the supermarket," she says happily. The cost is very low—only 100 yuan per year for a plot, including seeds, tools, and water. There are also volunteers who teach organic farming methods. The garden has become a popular place for both the elderly and young families. Children learn where food comes from, and neighbours get to know each other. However, some people complain about the smell of fertilizer(肥料) and insects problems. The committee has promised to use eco-friendly methods to control these problems. They are also planning to add more gardens in other districts. 根据短文内容回答问题,每题答案不超过10个单词。 76.What problems did the shared vegetable garden solve? 77.How much does it cost to rent a plot for one year? 78.Who teaches organic farming methods in the garden? 79.What problem do some people have with the garden? 80.What do you think of the "shared vegetable garden"? 八、书面表达(满分20分) 自“苏超”赛事举办以来,徐州队成功走进了全国人民的视线。不管是在赛场上努力的运动员,还是指导他们的教练,都是我们徐州人心中的英雄。假如你班将要开展一次以“The hero in my heart”为题的英语班会,请你根据下面的要点与要求写一篇英语发言稿。 要点: 1.你心中的英雄是谁? 2.为什么他/她是你心中的英雄? 3.你从他/她那里学到了什么? 要求: 1.文中不得出现真实的校名和人名; 2.词数100左右(开头和结尾已给出,不计入总词数)。 The hero in my heart Good afternoon, everyone!
