Every night, I lay in bed for hours, unable to fall asleep. By morning, I felt exhausted—I even nodded off in my history class once. My mom noticed my tired eyes and took me to see a sleep doctor.The doctor asked me to keep a “sleep diary” for a week. I wrote down when I went to bed, what I did before sleep, and how I felt the next day. After looking at the diary, the doctor found the problem: I used my phone for 30 minutes before bed, and I drank a cup of iced milk tea every evening. The doctor explained that blue light from phones stops our brains from making melatonin—a chemical that helps us sleep. The sugar in milk tea also keeps our bodies awake.The doctor gave me three rules: first, put my phone away 1 hour before bed (I could read a paper book instead); second, drink warm milk instead of milk tea in the evening; third, keep my bedroom cool and dark (no night lights). At first, it was hard—I wanted to check my messages. But I stuck to the rules.After two weeks, something amazing happened. I started falling asleep within 15 minutes of lying down. In the morning, I woke up feeling fresh and ready for school. I even joined the school’s morning run club—something I never had energy for before. My history teacher also noticed the change: “You’re more active in class now!”This experience taught me that small, consistent changes in habits are better than big, sudden ones. Healthy sleep isn’t just about “sleeping more”—it’s about sleeping well. Now, I tell my friends about my sleep rules whenever they complain about being tired.根据短文内容，选择最佳答案。（ ）16.

While some habits are different, they all aim to keep the mind and body in good shape. The chart below compares healthy habits from three countries.In Japan, washoku isn’t just about food—it’s about “eating with all senses”. People use small plates to control portion sizes, and they eat slowly to enjoy each bite. This helps them avoid overeating. Studies show that Japanese people have one of the lowest rates of obesity in the world, partly because of washoku.Finns take saunas very seriously. Even schools and offices in Finland have saunas! The heat from saunas makes people sweat a lot, which helps remove toxins from the body. Finns also believe that saunas bring families closer—they often talk and laugh together in the sauna.Yoga in India is more than just exercise. Many people do yoga at sunrise in parks or on rooftops. It’s not just for adults—children learn simple yoga poses in school to improve their focus. In recent years, yoga has become popular worldwide because it’s easy to do and doesn’t need special equipment.While these habits are different, they share one thing in common: they’re simple and can be done regularly. No matter which culture they come from, healthy habits help us live longer and happier lives.根据短文及图表内容，选择最佳答案。（ ）21. What is washoku?A. A type of Finnish sauna.B. Traditional Japanese food.C. An Indian yoga pose.D. A UNESCO building.（ ）22. Why do Finns jump into cold water after a sauna?A. To cool down quickly.B. To improve blood circulation.C. To clean their bodies.D.

To share food with family members.D. To keep food warm for a long time.（ ）24. What is a common feature of the three habits?A. They all need special equipment.B. They’re all done only by adults.C. They’re simple and can be done regularly.D. They’re all about eating healthy food.（ ）25. What does the underlined word “toxins” in Paragraph 3 refer to?A. Healthy nutrients in food.B. Harmful substances in the body.C. Relaxing chemicals in the brain.D. Useful minerals in water.CShould Schools Ban Junk Food from Vending Machines?In recent years, many schools have debated whether to ban junk food (like chips, candy, and sugary drinks) from vending machines. Some people think it’s a good idea, while others disagree. In my opinion, schools should ban junk food from vending machines—it helps students develop healthy habits and protects their health.First, junk food is bad for students’ physical health. Most junk food is high in sugar, salt, and fat, but low in vitamins and protein. Students who eat junk food regularly are more likely to have problems like obesity and toothaches. A study by the World Health Organization found that 1 in 5 teenagers worldwide is overweight—many of them eat junk food at school. Banning junk food from vending machines can reduce students’ access to unhealthy snacks.Second, banning junk food helps students form good eating habits. Teenagers are more likely to choose healthy food if junk food isn’t easy to get. For example, if vending machines sell fruit cups instead of candy, students will gradually get used to eating fruit. These habits will stay with them even after they leave school—helping them stay healthy for life.Some people argue that “students should have the freedom to choose what to eat”. But schools have a responsibility to guide students, not just give them freedom. Junk food is addictive—once students get used to its sweet taste, they find it hard to choose healthy food. Schools need to help them break this addiction.Others say “banning junk food will make vending machines less profitable”. But schools can replace junk food with healthy options like nuts, yogurt, and whole-grain crackers. These items are also popular, and they can make money too.In short, banning junk food from school vending machines is not about “taking away freedom”—it’s about giving students a healthy environment. Schools should put students’ health first and make this change as soon as possible.（ ）26. What is the writer’s opinion on banning junk food from school vending machines?A. It’s a bad idea because it takes away students’ freedom.B. It’s a good idea to protect students’ health and form good habits.C. It’s unnecessary because students rarely eat junk food.D. It’s too expensive for schools to do.（ ）27. Why is junk food bad for students?A. It’s high in vitamins and protein.B. It’s low in sugar, salt, and fat.C. It can cause obesity and toothaches.D. It’s too expensive for students to buy.（ ）28. What do some people argue against banning junk food?A. Students should have the freedom to choose food.B. Junk food is good for students’ health.C. Vending machines will disappear if junk food is banned.D. Healthy food is harder to find than junk food.（ ）29. How can schools keep vending machines profitable after banning junk food?A. By increasing the price of all items.B. By selling healthy options like nuts and yogurt.C. By reducing the number of vending machines.D. By asking students to bring food from home.（ ）30. What is the main purpose of the passage?A. To explain how junk food is made.B. To encourage students to eat more junk food.C. To argue that schools should ban junk food from vending machines.D. To describe the history of vending machines in schools.D“Healthy Teen” APP User GuideWhat Is “Healthy Teen”?“Healthy Teen” is a free APP designed for students aged 12-18.
