Recently a new survey looked into teenagers’ mental condition in 28 places in China and got answers from more than 21,500 teenagers. DO YOU FEEL STRESSED? Frequency (频度): Top 3[32] ● four or more times each week: 12% ● Getting into a good school (11,779 teenagers) ● two or three times each week: 59% ● Parents’ expectations (9,386 teenagers) ● once a week: 26% ● Never experience anxiety: 3% ● Socializing (社交) (4,729 teenagers) Top 3 Ways to Lower Anxiety ● Listening to music (12,007 teenagers) ● Doing exercise (7,035 teenagers) ● Talking to someone (6,330 teenagers) 21. ________ of students who took part in the survey never experience anxiety. A. 3% B. 12% C. 26% D. 59% 22. The most popular way to lower anxiety is ________. A. listening to music B. doing exercise C. talking to someone D. reading books 23. You can read the passage in the ________ part of a newspaper. A. health B. culture C. travel D. science B Comics and graphic stories (图像故事) have been popular around the world for over a century. They started as simple drawings in newspapers in the late 1800s. By the mid-1900s, comics grew into colorful books with exciting characters like superheroes and funny animals. Today, they are not just for kids — many adults enjoy them too! Comics use pictures and words together to tell stories. The pictures are placed in panels (small boxes), and characters often speak through speech bubbles. Graphics novels are similar to comics but are usually longer and tell complete stories in one book. They cover many topics, from fantasy adventures to real-life events. While comics are often short and published weekly or monthly, graphic novels are like thick books that readers can finish in one time. Both use art styles to show emotions — for example, dark colors might mean sadness, while bright colors show happiness. Teachers have started using comics in classrooms. Why? Because combining pictures and words helps students understand difficult ideas. A science comic might explain how plants grow using images and simple texts. Some students even create their own comics to practice writing and drawing skills. Comics also encourage people who don’t like reading long texts to enjoy stories. 24. What is the main idea of the second paragraph? A. How to draw speech bubbles correctly. B. Differences between comics and graphic novels. C. The history of newspaper cartoons. D. Why adults dislike graphic novels. 25. What can we infer about comics from the text? A. They are only popular with young children. B. They use pictures and colours to express feelings. C. They are less interesting than regular books. D. They were invented in the 21st century. 26. Why might a teacher use comics in class according to the text? A. To make complex topics easier to understand. B. To help students enjoy drawing more than writing. C. To replace all textbooks. D. To encourage students to read fewer books. 27. Which statement about graphic novels is NOT true? A. They usually tell a full story in one book. B. They are often thicker than comic books. C. They are published weekly or monthly. D. They can include stories based on real life. C ①One of the world’s most dangerous sports is mountain climbing, and one of the most popular places for this is the Himalayas. The Himalayas run along the southwestern part of China. Of all the mountains, Qomolangma rises the highest and is the most famous. It is 8,848.86 meters high and is very dangerous to climb. Thick clouds cover the top and snow can fall very hard. Even more serious difficulties include freezing weather conditions and heavy storms. It is also very hard to take in air as you get near the top. ②The first people to reach the top were Tenzing Norgay and Edmund Hillary on May 29,1953.After a long and difficult climb, troubled by heavy snow, freezing wind and the lack of oxygen, they finally reached the top. They could only spend about fifteen minutes on the summit before they had to come down. The first Chinese team did so in 1960, while the first woman to succeed was Junko Tabei from Japan in 1975. ③Why do so many climbers risk their lives? One of the main reasons is that people want to challenge themselves in the face of difficulties. The spirit of these climbers shows us that we should never give up trying to achieve our dreams. It also shows that humans can sometimes be stronger than the forces of nature. 28. How high is Mount Qomolangma? A. 8,848.86 kilometers. B. 8,886.48 meters. C. 8,848.86 meters. D. 8,886.48 kilometers. 29. According to the passage, when climbing Mount Qomolangma, what difficulties may climbers meet? A. Thin clouds and heavy storms. B. Freezing weather and thick clouds. C. Heavy storms and lack of water. D. Thin clouds and freezing weather 30. What does the underlined word “summit” in Paragraph 2 mean? A. top B. side C. foot D. bottom 31. What does the spirit of climbers tell us? A. Never give up. B. All roads lead to Rome. C. Practice makes perfect. D. Risk lives to climb D ①What should we do if one of our classmates suddenly falls ill or gets hurt? ②Here are some steps (步骤) you should follow. But always remember to look for medical care after first aid if the wound (伤口) is serious. ③Broken bones (骨头): Take away clothing from the wound. Use an ice pack. Don’t move the hurt body part while waiting for the doctor to arrive. ④Animal bites (咬伤): Wash the bite area with soap and water. Bandage the wound with a clean cloth if it is bleeding. If the bleeding has stopped, cover the area with a bandage and take the person to the hospital. Make sure you remember what kind of animal it is so that the doctor can find the right way to treat (治疗) him or her at once. ⑤Fainting (昏厥): Have him or her lie with feet lifted (抬起) a little. Don’t move the body if you think there might be wounds from the fall. Make sure he or she can breathe and let in fresh air. Clean the person’s face with a cool cloth. ⑥Nosebleeds: Have the person sit up with his or her head tilted (倾斜) forward a little. Do not have the person tilt his or her head back because this may cause heavy breathing or coughing. Pinch (捏) the lower part of the nose for at least 10 minutes. 32. When an animal bite happens, we should ________ first. A. put an ice pack on the wound B. take the hurt person to the hospital C. wash the bite area with soap and water D. try to stop the bleeding with a clean cloth 33.

Young people, even teenagers, are sometimes the victims (受害者). This has made many people worry: What causes it, and more importantly, how can we protect ourselves? Sudden cardiac death happens when the heart suddenly stops working. It often comes without warning. Studies show that there are several reasons behind it. Too much stress and lack (缺少) of sleep can make the heart weak. Besides, most young people today are fond of eating too much fast food or sugary drinks, but unhealthy eating habits can harm the heart over time. Many people think that exercising more can keep their hearts healthy, but exercising too hard without enough rest is not the case. Doing too much hard exercise without enough rest can also be dangerous. What can we do to prevent it? We should try to get at least 8 hours of sleep every night, eat more fruits, vegetables and whole grains. Most importantly, don’t push yourself too hard. Regular exercise is good for the heart, but if you feel very tired or uncomfortable, stop and rest. A healthy life and wise exercise can keep us away from sudden cardiac death. Some schools have started to take action. They put AEDs (自动体外除颤器) in the school, which can save a person’s life if the heart stops. They teach students how to do CPR (心肺复苏). This reminds us that learning some helpful first aid skills can make a big difference in an emergency. It can also help us take action in time before the sudden cardiac death totally happens. 41. Do teenagers sometimes suffer sudden cardiac death? ________________________________________________________________ 42. How many hours do we need to sleep every night? ________________________________________________________________ 43. According to the passage, what may cause sudden cardiac death? (3 points) ________________________________________________________________ 44.

Please write a short note for the poster to encourage them to pay more attention to heart illness prevention.

It is truly exciting to get new knowledge across different subjects. Take math, for example. When we finally work out a difficult problem, the sense of achievement is just like finding hidden treasure. In science classes, experiments open a door to the mysteries of nature. Moreover, the time spent with friends is valuable. During breaks, we exchange the latest gossip, funny stories, or simply relax together. Taking part in sports as a team, such as basketball or football, not only keeps us fit but also creates memories that will last a lifetime. However, there are challenging times. We have to face mountains of homework and too many tests. Before big exams, we often stay up late to study and lose sleep and free time. And the competition with classmates can be a lot, which makes us feel worried about falling behind. Thankfully, there are ways to deal with these challenges. To manage the heavy schoolwork, we can create a daily or weekly study plan, deciding when to do each subject according to its difficulty. When facing competition, we should focus on setting personal goals. Every small achievement, like getting a difficult question right, should be celebrated. A sense of satisfaction allows us to feel good about ourselves. In conclusion, by valuing the happy moments and actively dealing with the challenges, we can make our school days more colorful and meaningful. School life is an unforgettable journey for students. It is full of ____54____. At school, students can enjoy lots of things. The joys include learning new things, ____55____ and taking part in team sports. They are all valuable moments.
