He said, “Why not use a magnifying glass (放大镜) to shine on the egg ” He told me that Miss Li once said that the magnifying glass could focus (聚焦) the sunlight and cause the temperature to rise. “So we could fry the egg on the road in this way,” my brother said.

China is making big efforts to help people control their weight and live healthier lives. The government has started a three-year “Weight Management Year” plan from 2024 to 2027 to fight against obesity (肥胖). Obesity can cause serious health problems like diabetes and heart disease. Here’s what you should know about the new guidelines:
First, it’s important to check your BMI (Body Mass Index). For adults, a healthy BMI is between 18.5 and 24. If your BMI is between 24 and 28, you are overweight. A BMI of 28 or more means you are obese. Also, doctors suggest measuring your waist. Men should keep their waist under 90 cm, and women under 85 cm.
Eating well is very important, and exercise is just as important! When it comes to food, choose whole grains like brown rice, fresh vegetables, and lean proteins such as fish, chicken, or beans. Don’t eat fried foods and sugary snacks, and also eat less salt and oil. Interestingly, the guidelines even include fun local dishes—like “stewed fish” from Northeast China or “noodles with chili oil” from the Northwest—to make healthy eating tasty and full of local flavor.
For exercise, try to do 150—300 minutes of activities like walking, cycling, or dancing every week, and do strength exercises twice a week. If you sit for a long time while studying, stand up and stretch for 3—5minutes every hour.
Besides diet and exercise, small daily habits can also make a big difference. Teens should sleep 7 hours every night because bad sleep can make you gain weight. Try to eat vegetables first, then meat, and finally rice or bread during a meal to control how much you eat.
Schools and communities are also helping. For example, schools in Shanghai now make sure students exercise for at least two hours every day, and hospitals have “weight clinics” with diet plans, exercise advice, and even traditional Chinese ways like acupuncture. By 2030, China hopes to slow down the increase of obesity through education and support.
Remember, losing weight isn’t about being perfect—just start with small changes, like drinking water instead of soda or taking the stairs instead of the elevator. With these easy steps, everyone can have a healthier future.
18. What is the main goal of China’s “Weight Management Year” plan
A. To make traditional Chinese food popular.
B. To encourage people to join sports competitions.
C. To teach students how to cook healthy meals.
D. To reduce obesity and improve public health.
19. What might happen if a student sits for 4 hours without standing up
A. They will finish homework faster. B. They might gain weight more easily.
C. They will become stronger. D. Their BMI will improve.
20. What does the sentence “losing weight isn’t about being perfect” suggest in the last paragraph
A. People should never make mistakes. B. Small changes are enough to start with.
C. Only strict diets can help lose weight. D. Exercise is more important than diet.
21. What can we know from the text about the relationship between sleep and weight
A. Longer sleep always leads to weight loss.
B. Sleep has nothing to do with weight.
C. Enough sleep helps teens keep a healthy weight.
D. Adults need less sleep than teens to control their weight.
D
On December 30,2024,the tunneling (开凿隧道) of Tianshan Shengli Tunnel, the world’s longest expressway (高速公路) tunnel, was completed. It goes through the snow-covered mountains of Xinjiang Uygur Autonomous Region.
As an important part of the Urumqi-Yuli Expressway, this new tunnel with a total length of 22.13 km will go across the Tianshan Mountains one of the longest mountain ranges in the world, and open a new pathway to southern Xinjiang. The construction of the tunnel started in April 2024.
When opened to traffic in 2025, it will cut travel time through the Tianshan Mountains from 3 hours to about 20 minutes, and the journey from Urumqi to Korla, a city in southern Xinjiang, will be shortened from about 7 hours to about 3 hours.
The workers had to overcome many difficulties and be creative in building the tunnel, which is in a high plateau (高原) area with complicated geological (地质的) conditions. They have used the construction scheme (方案) of three drifts and four shafts (竖井). Two specially designed tunnel boring machines (隧道掘进机) have been used in the construction of the middle drift to create a working platform for tunneling.
This is the first time that a tunnel boring machine has been used to build a road tunnel in China.
The use of new technologies has cut the construction time of the tunnel from 10 years by using the traditional drilling method to just more than four years.
22. What can we learn about the Tianshan Shengli Tunnel
A. It is the longest tunnel in the world.
B. It is part of the Urumqi-Yuli Expressway.

C. The history of the tunnel. D. The building process of the tunnel.
24. What does the underlined word “complicated” in Paragraph 4 mean

25. What’s the passage mainly about
A. The history of the Tianshan Mountains.
B. The completion of the Tianshan Shengli Tunnel.
C. The difficulty in building roads in Xinjiang.
D. The development of tunnel boring machines.
