You can get great calorie burning effects with the following exercises. Running Running is one of the best calorie burners out there. An average person can burn anywhere from 500 to 1,000 calories in one hour of running. Speed and pace are all factors that can affect calorie burning. But running uses every muscle group in the body, allowing you to burn more calories. High Intensity Interval (高强度间歇运动) Training (HIIT) If you want intensity, HIIT is right for you. This physical exercise involves working hard in intervals, then resting. Because your heart rate will stay at a high level, you’ll burn more calories in less time. On average, a person will burn 400 to 600 calories in 30 minutes. Jumping rope This childhood activity can actually do wonders for your health. Jumping rope is great for strengthening the lower and upper body while training your balance and coordination (协调能力), because your mind has to work while you jump. Jumping rope can burn 600 to 1,000 calories in an hour. Swimming Swimming is a low-intensity form of exercise that also uses muscle groups of your body. In just 30 minutes of swimming, an average person can burn 200 to 300 calories. Swimming also helps to shape body, control blood pressure, and increase strength—all great reasons for you to jump into the water. 1. Which kind of exercise burns the most calories in an hour? A. Running. B. Swimming. C. Jumping rope. D. High Intensity Interval Training. 2. Who may also be interested in the third exercise? A. Those who want to train their mind. B. Those who want to have good balance. C. Those who want to control blood pressure. D. Those who want to do low-intensity activities. 3. What is the purpose of the text? A. To encourage people to compete in sports. B. To teach people how to do exercise. C. To provide ways to burn calories. D. To promote a healthy lifestyle. B Despite the fact that burgers, chips and fries are known as some of the most unhealthy food we can eat, they are still the most popular food. There are a few reasons behind that. First, junk food is generally easy to get and take with you. This convenience is a major draw for many, especially people who are always on the go. Restaurants like McDonald’s and KFC can be found outside many schools and workplaces, providing meals in under a minute. Secondly, junk food contains a lot of added sugar and fat. This kind of food causes our brain to send out certain chemicals, which produce the feeling of relaxation, pleasure and enjoyment. That’s why such food is called “comfort food”. Thirdly, our ancestors didn’t have such easy access to the huge variety of food we come across every day. They didn’t have the convenience of having food as easily as we do. So they made it a habit to eat as much as they could to survive and protect themselves from the hard natural conditions. The cave mentality (心理) is passed down to us, which makes us believe that we can never have enough food that is high in sugar and fat, no matter how crazily we eat. Besides, when we are too worried and tired to relax, our body produces cortisol (皮质醇), which increases the sugar content in the blood, so it can be used as energy to aid in fat and carbohydrate metabolism (碳水化合物代谢). Additionally, it is also found to increase hunger. That’s the reason why when we’re thinking about unpleasant things, we prefer foods that are high in sugar, fat and carbohydrate, that is to say unhealthy food. 4. Why are McDonald’s and KFC mentioned? A. To show they take up the best site. B. To show they provide good service. C. To show they are famous for their taste. D. To show they make junk food easy to get. 5. What does the author want to tell us in Paragraph 4? A. We need all kinds of food. B. Our ancestors lived a hard life. C. We are born to eat more than we need. D. It is difficult for us to change our habits. 6. What is a cause of the increase of sugar content in our body? A. Too much stress. B. A wish for food. C. A fast metabolic rate. D. Not having enough energy. 7. What is the text mainly about? A. How harmful junk food is. B. Why fast food is so delicious. C. How we can develop a healthy lifestyle. D. Why we love unhealthy food so much. C “Age is just a number” is a saying that some people might disagree with, but for healthy and fit great-grandmother Anne Sheppard, nothing could be more true. At 100 years old, Anne can kick, crunch and do full push-ups. And she is always exercising with other fitness fans who are almost 70 years her junior in the gym. South Melbourne-born Anne worked at the local clothing factory while her husband Max was away at work with the army. When the couple retired in 1981, they signed up to their local gym, where Anne is still a member 40 years later. “I feel stronger and fitter than before!” Anne says in an interview from her gym in Melbourne. She has just finished a rigorous training class, one of five group courses she attends throughout the week. “I just love it and I want to keep going as long as I can,” she smiles. “It’s part of my life now—my husband has passed away and now I’m on my own. The gym is my second family and I’d be lost without them.” “Anne is a superstar,no matter where she goes,everyone is attracted to her!I know she inspires us to do whatever we set our minds to. We’re all jealous because we want to get to 100 years old and be like her,” says Jan, a friend of Anne in the gym. Exercise has always been an important part of life for Anne. Despite going to the gym three days a week, Anne also keeps active in other ways, and regularly walks to and from the local supermarket. Life has now slowed a little bit for Anne. As for her next personal best, her goal is to keep going to the gym. That’s how Anne enjoys her life. 8. What is the purpose of the first paragraph? A. To summarize the passage. B. To introduce the main character. C. To explain the meaning of a saying. D. To ask for background information. 9. What can we learn about Anne in paragraph 2? A She used to work with her husband in the army. B. She takes exercise as an important part of her life. C. She became a member of the local gym 70 years ago. D. She stopped exercising after her husband passed away. 10. What does the underlined word “it” refer to in paragraph 2? A. The training class. B. The interview. C. The smile. D. The week. 11. Which of the following can be the best title of the passage? A. Anne, Enjoying Her Slow Life B. Anne, an Attractive Gym Coach C. Anne, a 100-year-old Fitness Lover D. Anne, Coming to Her Next Personal Best D According to reports, three-quarters of all crops around the world depend on pollinating (授粉的) insects like bees and butterflies. By pollinating, pollinators enable the production of seeds. Without them, crop farming can become extremely difficult or costly threatening food supplies and prices globally. Research has shown a rapid and consistent decline in pollinator populations. Average butterfly populations have almost halved since 1991 and bee populations in particular face a sharp decline. Given the world’s growing dependence on these insects, we can only expect the problem to worsen if no action is taken. Much has been written about how intensive farming practices the use of chemical pesticides and pollution are threatening the survival of these helpful insects. To add to the already critical situation, global warming is contributing significantly to the rapid disappearance of pollinators. Climate change is a major threat to pollinators, with rising temperatures and increasing frequency and intensity of extreme weather events affecting the food sources and habitats, on which pollinators depend for their survival. Climate change also changes the timing and availability of lowering plants, leading to mismatches between pollinators and their food sources. A study has found that climate change has shifted plants’ blooming to earlier times and caused certain plants to move to higher areas, resulting in a decline in pollination. Another study has found that climate change could lead to a decline in the quality of nectar, which is the main food source for many pollinators. As temperatures rise, the sugar content of nectar decreases, making it less nutritious for pollinators. This leads to a decline in the health and reproductive success of pollinators, as well as a decline in the pollination of plants. Needless to say, cutting global emissions is key. It’s essential that we continue to advocate for emission reductions. From country-level to individual businesses, more concrete roadmaps to net zero are a must. We must at least minimize, if not prevent, the usage of pesticides, since these chemicals are harmful to pollinators and can have a far-reaching effect on pollination as a whole. 12. What does paragraph 1 try to show? A. The influence of crop crises. B. The importance of pollinators. C. The serious challenges faced by humans. D. The increasing difficulty of crop production. 13. How does the author sound in paragraph 2? A. Curious. B. Suspicious. C. Humorous. D. Anxious. 14. What do paragraphs 3-4 mainly talk about? A. How climate change has affected pollinators. B. Causes of the decline in pollinator populations. C. The importance of pollinators to the ecosystem. D. Why chemical pesticides are harmful to pollinators. 15. What is a suggestion for helping pollinators? A. Starting keeping bees. B. Reducing pesticide use. C Increasing the amount of nectar. D. Building more habitats for pollinators. 第二节(共5小题;每小题2.5分，满分12.5分) 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。其中有两项多余。 Five Ways to Be Healthy on a Budget ●Go to bed an hour earlier. Lighting and electronics, including TVs, laptops and computers, account for around 30 per cent of your electricity usage. So it’s obvious that going to bed earlier could save you money. Getting adequate sleep makes you less stressed and puts you in a better mood, as well as improving your immune system and helping to protect you from heart disease, diabetes (糖尿病) and dementia. ____16____ ●Get fit on the cheap. There’s no need for an expensive gym membership or classes, or costly kit: the internet is a rich resource for videos on activities as varied as yoga, high intensity or low-impact workouts, or dance. ____17____ Being outdoors in nature is also good for your mental health. ●Abandon the car for short journeys. For local things or meeting people, walk or cycle. This will save money on fuel, plus help prevent you from being too sedentary (久坐的). ____18____ Besides, it is linked with conditions like heart disease and Type 2 diabetes. ●____19____ Meat is expensive, so substitute other, cheaper forms of protein a couple of times a week.

He had always found joy in the rhythmic tides and the ocean waves against the shore. The salty wind and the cries of the seagulls (海鸥) had been like a comforting song to him during his childhood. However, all these changed over the years. Every time he wandered along the familiar stretch of sand, his heart sank. The once charming beach was now littered with plastic bags, bottles and other wastes, a distinctive contrast to the natural beauty that had always absorbed him. The sight was a painful reminder of the harm the locals were bringing to the very land where he was growing up. Christian felt a deep sense of loss and responsibility. Previously, he had seen the news reports about the severe effects of plastic pollution on the oceans, and the images of sea creatures stuck in plastic wastes haunted (萦绕于脑际) him. Determined to make a change, Christian decided to take action. He knew he couldn’t solve this problem alone, but he could start something that might grow into a powerful movement. With the passion and belief of a young man who loved his ocean and his land deeply, he founded an organization called Waves of Change. The early days presented challenges in calling on volunteers. He began by reaching out to the students in his school. He shared the shocking reality of the polluted beaches and the urgent need to reduce plastic litter. To his delight, gradually more and more schoolmates started showing interest in the organization and many were eager to join in the cause. They were all too familiar with the beauty of the ocean and were equally saddened by the damage they had witnessed. As high school students, Christian and other members properly allocates (分配) time to balance the cause and their academic work. 注意： 1. 续写词数应为150左右； 2. 请按如下格式在答题卡的相应位置作答。 Together, Christian and other members did a lot of things in their free time. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Their efforts finally paid off. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 听力答案：1-5 BBACB 6-10 BCCAB 11-15 ACABC 16-20 ABAAC 琼海市嘉积中学2023-2024学年第二学期高二期中考试 英语科试题 (时间：120分钟 满分：150分) 欢迎你参加这次测试，祝你取得好成绩! 第一部分 听力(共两节，满分30分) 第一节 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话仅读一遍。 1.

These unhealthy habits can significantly impact our physical and mental well-being. To address these concerns, it is crucial to take regular breaks during study sessions to prevent tiredness. Additionally, promoting physical activities during school hours can encourage students to engage in movement and enhance our physical health. Furthermore, students should be educated on the importance of maintaining a balanced lifestyle. By prioritizing health and well-being, we can improve our academic performance, enhance our mental state, and build a foundation for a brighter future. Together, let us take the necessary steps to maintain a healthy life. 第二节(满分25分) 【47题答案】 【答案】参考范文： Together, Christian and other members did a lot of things in their free time. They passionately designed posters, spreading awareness about the harmful effects of plastic pollution. They organized regular clean-up events on the spot, not only to remove the existing waste but also to offer the participants an opportunity to witness the seriousness of the problem in person. Christian and his team also started a social media campaign, sharing educational content and updates about their initiatives. Besides, they patiently educated the local community about the importance of using reusable bags and other eco-friendly alternatives. Their efforts finally paid off. As the weeks turned into months, the tireless work of Waves of Change didn’t go unnoticed. Local businesses began to take an interest in their cause, offering support by reducing their own plastic usage and promoting Waves of Change to their customers. The community members were more conscious of their plastic consumption. The organization grew rapidly, with more and more volunteers joining the ranks, all dedicated to the cause of protecting oceans. The ocean, which had been a constant source of joy for Christian, is now thriving once more. 听力答案：1-5 BBACB 6-10 BCCAB 11-15 ACABC 16-20 ABAAC 第1页/共1页 学科网（北京）股份有限公司 $$
