Now I’d like to recommend four such watches to you. Polar Grit X Pro Sapphire glass, which is tough and scratch-resistant, is typically an add-on or upgrade feature, so you’ll be glad to know that the Polar Grit X Pro comes with this durable screen material. On top of that, Polar claims that the watch will withstand temperatures of -68 degrees up to 122 degrees F so you can stay connected on hikes in even the most extreme places in the world. Price: $500 Amazfit GTR 3 Pro If you want a watch to double as your fitness tracker and everyday watch, the Amazfit GTR 3 Pro is a good bet. It has 150+ sports modes.

Price: $230 Fitbit Charge 5 The Fitbit Charge 5 is perfect for those who only need a GPS watch to track basic fitness activities and personal health features like stress, heart health, sleep, and oxygen saturation. The price reflects that there are only 20 exercise modes and a water-resistance depth of 50 meters.

On the cover of my notebook in 2019, I wrote, “Discover the joy again.” It was intended to remind me to play more. Sometimes I’d get a rare assignment where I could breathe — for example, photographing an article on tea for an airline magazine. I took the job hoping to make interesting, almost movie images, but at the end of the day, I found I’d made nothing of the sort. Packing up my camera, I felt like a failure. On the drive back to the hotel, I noticed heavy steam rising from a building up ahead. Arriving at the scene, I opened the car door — and realized it was a tourist attraction traditionally pulled by a steam engine. Then, out of nowhere, a figure ran toward me. I picked up my camera and quickly made three pictures. One was out of focus. One was poorly composed. But one worked. When I submitted my pictures to the editor for the tea article, this one wasn’t chosen to be published, but I knew it meant something to me. I had been looking for good luck in my own life. This photograph symbolized exactly that. I was 27 when I first traveled to India after the sudden passing of my father. Over many months, with my best friend, I traversed India with no phone, with limited Internet, and with healing as my compass. I climbed mountains, swam in the sea, and lived in relief entirely. As I learned to travel to some of the world’s cities with the largest population, I began to see life with more color and magic. I permitted myself to walk aimlessly, with no goal but to observe, and each moment became a dance. If this journey taught me anything, it’s that what comes next will bring its own magic. 4. What can we know about the author from the first two paragraphs? A. He himself went through wars. B. He decided to live a relaxed life. C. He always made movie photos. D. He mainly worked for an airline magazine. 5. What happened to the author on the drive back to the hotel? A. He knocked into a steam engine. B. He took photos of the steam engine. C. He was attracted by the steam engine. D. He met a person of whom he took three photos. 6. What did the author think of the photo of the running figure? A. He thought highly of it. B. He thought little of it. C. He thought it would be chosen. D. He thought it meaningless. 7. What did the author learn from his journey to India? A. He learned to dance. B. He learned to travel around major cities. C. He learned to pursue life goals. D. He learned to accept what happened. C On August 1, 2023, new rules went into effect in the United States that make it against the law to sell most incandescent (白炽的) light bulbs. Incandescent light bulbs have been common since the late 1800s. They use electricity to create light by heating a metal wire, which glows. Over 90% of the electricity used by the bulbs goes into making heat — not light. Since 2005, countries around the world have been banning incandescent bulbs. That’s what’s happening in the US. The new rules don’t actually make incandescent bulbs illegal. They just say that light bulbs that are sold must be able to create a certain amount of light (45 lumens) with a certain amount of energy (l watt). Most incandescent bulbs can only create about 15 lumens with 1 watt. These days, the best way to replace incandescent bulbs is with LED light bulbs. These bulbs can create about 75 lumens with 1 watt of electricity. And they can last 25 or more times longer than incandescent bulbs. Though the rule just took effect at the beginning of August, it was first created in 2007. Since then, the rule has been delayed many times, usually for political reasons. In the early 2000s, LED bulbs cost more money than they do today, and weren’t nearly as good. But in recent years, people have been switching over to LED lights, even without the rule. The lights have become more and more popular, since they use less energy and save people money by lasting longer. The new rules will also help the environment. Over the next 30 years, LED bulbs are expected to help prevent a huge amount of pollution in the US — about as much as would be used by 28 million homes in one year. That will be an imperative step in tackling the climate crisis. 8. Why does the author mention incandescent light bulbs in Paragraph 2? A. To explain how they work. B. To show they used to be important. C. To show they aren’t good lighting sources. D. To explain how light is usually made. 9. What do the new rules in America mean? A. New incandescent bulbs will be invented. B. Using incandescent bulbs has been prohibited. C. No more incandescent bulbs will be produced. D. Incandescent bulbs should be mostly replaced. 10. What is shown about LED bulbs? A. They’re great replacements for incandescent bulbs. B. They’re cheaper than incandescent bulbs. C. They’re widely used all over the world. D. They’re unknown to many Americans. 11. What does the underlined word “imperative” in the last paragraph probably mean? A. Workable. B. Important. C. Interesting. D. Challenging. D As the pandemic makes clear, cities are possibly humanity’s greatest invention, but cities with huge populations also make us easily suffer from the rapid spread of disease. Yet humans aren’t the only species that face this problem. Honeybees have lived social lives for tens of millions of years, making them some of the most experienced in the battle against infection. And over time, natural selection has given them quite a few impressive strategies for reducing transmission within bee groups. However, these strategies are not enough to prevent every threat. Honeybees are battling their own global disease, for which they were totally not prepared. A parasitic mite (寄生螨) originally existed only in the groups of Asian honeybees, but later jumped to infect Western honey bees. Today, it has spread to every region where honeybees are kept except Australia and a handful of remote islands, quickly becoming a global disease of the bees. If left untreated, a group of bees will typically die from the mites within two years. These infections, plus farm chemicals and poor nutrition, have forced beekeepers to struggle to keep their bees alive. Of the 2.6 million honeybee groups in the US, over half of them have parasitic mite. And that’s only the count of those bees that are tested and reported; the actual numbers are likely much higher. Beekeepers have still managed to slowly increase the number of groups they keep, on average, but at a much higher cost. Western honeybees did not grow with parasitic mite, and the Western bees lack the behavioral features those Asian honeybees have, like permanently burying the members infested by parasitic mite and, perhaps the most extreme strategy, where the bees are so sensitive to parasitic mite that they completely die as soon as infected, sacrificing themselves to prevent the mite from reproducing. 12. What might be the consequence of the invention of cities? A. It makes the pandemic clear to humans. B. Humans are easy targets of quickly spreading diseases. C. Cities have more population than ever. D. The spread of disease becomes faster and faster. 13. What can be learned about honeybees from the text? A. They have lived with infection for millions of years. B. They are not prepared for the pandemic like humans. C. Asian honeybees are facing a parasitic mite from the west. D. Natural selection offers them strategies to protect their species. 14. What’s the main trouble beekeepers are facing? A. How to prevent the honeybee groups from dying. B. How to calculate the exact number of honeybee groups. C. How to cut down on the cost of increasing honeybee groups. D. How to help honeybees with parasitic mite. 15. Which of the following would be the best title for the text? A. A special spreading disease B. Asian bees and Western bees C. The pandemic and city population D. Honeybees are struggling with their own disease 第二节(共5小题;每小题2.5分，满分12.5分) 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中的两项为多余选项。 The quality of your sleep is just as important as the quantity. Getting the right number of hours every night is unlikely to benefit you if you are frequently waking up, if you sleep at wildly different times, or if you sleep shallowly. Here are some tips that help you get quality sleep. ____16____ You will sleep the most soundly if you go to bed and wake up around the same time every day. ____17____ Work, children, and other demands on your time may determine your rhythm. Many sleepers, especially night owls, may be tempted to sleep in longer on weekends. Try to keep the same wake-up time, even on weekends. Determine your natural sleep schedule. If you have the freedom to determine your own sleep schedule, do so around the rhythms of your body. ____18____ Notice when you feel sleepy, and when you feel the most awake. To establish a natural sleep rhythm, spend a week or two waking up without an alarm clock. Keep a log with all the times you wake up. Stay asleep. ____19____ This can be difficult if you are an evening person, if you have children, or if you are a light sleeper. Making arrangements in your bedroom and winding down properly can make a huge difference, but so can prioritizing staying asleep. Tell yourself and tell everyone you live with that you need to stay asleep all night. Sleep enough. Most adults need to sleep between seven and nine hours a night. Teenagers need eight to10 hours of sleep, and school-aged children need at least 10 hours. Sleeping too little can expose you to higher risks of illness, anxiety, and disease. ____20____ A. Make lifestyle changes to promote better sleep. B. Establish a regular bedtime and wake up time. C. This rhythm helps your body prepare for sleep. D. Your body has natural waking and sleeping moments. E. Do everything in your power to avoid waking up at night. F. Sleeping too much, however, may reduce the quality of your sleep. G. If you haven’t fallen asleep after 15 minutes, get up and do a brief, relaxing activity. 第三部分：语言运用(共两节，满分30分) 第一节(共15小题;每小题1分，满分15分) 阅读下面短文，从短文后各题所给的四个选项(A、B、C和D)中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。 I had a terrible experience last year.

Little did I know that the real excitement wasn’t to begin until that night. While we watched the fireworks, I began to get an urge to go to the restroom, but I didn’t want to miss the show. I overheard my sister Isabel talking to my mom, and I got closer to them to hear what they were talking about. “Mom, I’m going to the bathroom with Lizette, okay?” said Isabel. “Okay,” my mom replied, “but stay together. I don’t want any of you getting lost. ” The second I saw my sisters leaving, I didn’t think twice before running after them—without telling my parents. As I followed them through the huge crowd of people, I started to lose sight of them. I began to panic as I scanned the crowd for them. Crazy thoughts ran through my head like “What if I never see my family again?” I gave up trying to find my sisters and tried to get back to my family, but I was completely mixed up. After searching for what seemed like forever, I couldn’t hold back my tears, and I started crying like I had never cried before. “Mommy!” I cried out. But everyone around me was too caught up by the fireworks to pay any attention to me. I tried to stop the scary thoughts that were going through my head and started running as fast as I could...anywhere...everywhere. I was going crazy. I’m only six, and I’ve gotten lost. “What have I done? How could I have been so dumb to run off without telling anyone?” I thought. With my face wet from tears, I kept running, pulling at people’s pants and crying, “Mommy!” I was hoping, wishing, that one of these adults would be one of my parents. 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。 Luckily, I felt a pat on my shoulder and a gentle voice came, “Are you lost?” _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Finally, through the crowd of people, I recognized a face. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 1-5BACAB 6-10BCCBA 11-15BBCCB 16-20 AACAC 2024—2025学年上学期高三假期检测 英语试题 第一部分：听力(共两节，满分30分) 第一节(共5小题;每小题1.5分，满分7.5分) 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.

It was a lady working at Disney. She picked me up and carried me through the crowd as she kept asking me where my parents had been standing. As I began to feel safe in the lady’s arms, I calmed down and thought for a few minutes. I remembered we had been leaning against a wooden fence. She carried me around the wooden fence, asking random people, “Is this your child?” “No. Sorry,” everyone kept saying. You’re sorry? Look at me. I’m looking for my mommy, I thought. Finally, through the crowd of people, I recognized a face. I was so happy. “Mommy!” I shouted as I pointed toward her so the lady could carry me to her. When the lady put me down, I ran to my mom and gave her a huge hug. I couldn’t let go of her. I didn’t want to lose her again. As I cried in my mother’s arms, my family thanked the nice lady for everything she had done for me. For the rest of the evening and the entire next day, I was more concerned with making sure that my parents were within my sight at all times than I was with seeing the sights at Disneyland. I look back at these memories and laugh at myself, but to this day, I always make sure to tell someone where I am going before I run off. 1-5BACAB 6-10BCCBA 11-15BBCCB 16-20 AACAC 第1页/共1页 学科网（北京）股份有限公司 $$
