A nature magazine. D. A health instruction.BOne night, I received a message from my former classmate, someone I hadn’t spoken to in 15 years. “Hey Mary,” she said. “I know you’ve always been an animal lover. I have a mini pig that is not getting along with my dogs. So I can’t keep the pig.” Of course, the whole situation was strange, but I’ve always been a trusting person. I replied “Let me do some research and I’ll get back to you.”I knew nothing about mini pigs. I didn’t know what they ate; and I had no idea how big they got. Once I started doing some Internet research, I found a few people claiming that “there’s no such thing as a mini pig,” but I was blinded by my sudden obsession and my faith in my onetime friend. She had said the pig was six months old and this mini pig would grow to be about 70 pounds, maximum. That was pretty close to the size of Shelby, one of my dogs. So I told my former classmate that I’d take the animal.It’s intractable enough bringing a pig back to the house I share with two dogs, two cats and my husband, Derek. But I knew I wanted the pig and the day finally came. When Derek went back, he stood in the door way like a statue. Every emotion other than happiness flashed across his face. He was extremely angry. The only positive thing I could say was, “She’s a mini pig! She’ll stay small!” Surprisingly, soon enough, the lovely pig smoothed things over by itself. Derek started talking about where the pig’s litter(窝)would go. You don’t care about “litter” of someone you’re getting rid of.However, a few months later, she’d started closing in on 80 pounds. It was becoming clear that I’d probably adopted a commercial pig and she was going to be enormous. While it might be unexpected, it’s more than worth it for the happiness she has added to our world.24. What did the author do immediately after receiving her former classmate’s message A. She decided to take the pig without hesitation.B. She discussed the matter with her husband Derek.C. She looked up information about mini pigs online.D. She asked the classmate about the pig’s habits.25. The word “intractable” in the third paragraph most probably means ______.A. easy and comfortable B. difficult to handleC. exciting and interesting D. common and predictable26. How did Derek feel when he first saw the pig A. Curious and interested. B. Shocked and angry.C. Sympathetic and warm. D. Relaxed and joyful.27. What is the main theme of the passage A. The challenges and joys of adopting an unexpected pet.B. The importance of trusting old friends.C. The differences between mini pigs and commercial pigs.D. The need for researching before keeping a pet.COf the 8,300 million tons of new plastic produced up to the end of 2015, 6,300 million tons have been thrown away. Most of that plastic waste is still with us, buried in landfills or polluting the environment. Micro plastics have been found in Antarctic sea ice, in the guts of animals that live in the deepest ocean trenches (海沟) and in drinking water around the world.But what if we could wave a magic wand and remove all plastics from our lives For the sake of the planet, it would be an attractive prospect — but we’d quickly find out just how far plastic has spread to every aspect of our existence.In hospitals, the loss of plastic would be disastrous. “Imagine trying to run a dialysis (透析) unit with no plastic,” says Sharon George, senior lecturer in environmental sustainability and green technology at Keele University in the UK. Plastic is used in gloves, tubing, blood bags, sample tubes and more.Some everyday plastic items are also vital for protecting health. Face masks — including plastic-based surgical masks and respirators (人工呼吸器) — have helped slow the spread of the COVID-19 virus. “A mask that you have for COVID is related to our safety and the safety of others,” says George. “The impact of taking that away could be loss of life if you took it away on a big scale.”Our food system would also quickly come apart. We use packaging to protect food from damage in transit and preserve it long enough to reach supermarket shelves. “I cannot imagine how plastic would be replaced completely in our system,” says Eleni Iacovidou, a lecturer in environmental management at Brunel University London.Replacing plastic packaging would set off a chain reaction in the environment. While glass has some advantages over plastic, such as being endlessly recyclable, a one-liter glass bottle can weigh as much as 800g compared to a 40g plastic one. When those heavier bottles and jars need to be transported over long distances, carbon emissions grow even more.It’s clear that replacing one material with another won’t solve all our plastic problems.28. What is the purpose of the first paragraph A. To give a definition. B. To report on a study.C. To introduce an argument. D. To describe a phenomenon.29. Why does Sharon George mention a dialysis unit A. To show the high cost of plastic medical products.B. To illustrate plastic’s necessity in medical work.C. To explain how dialysis units are usually operated.D. To compare plastic with other medical materials.30. What is Eleni Iacovidou’s attitude toward removing plastic totally in food system A. Doubtful. B. Supportive. C. Optimistic. D. Uninterested.31. What does the author want to convey through the text A. Plastic is too important to human life and should never be replaced.B. Medical and food industries depend entirely on plastic for development.C. Plastic pollution is the most serious environmental issue worldwide.D. Solving plastic problems requires more than simply replacing it with other materials.DYou stayed up too late browsing through your phone, answering emails or watching just one more episode.The next morning, you feel sleepy and impatient.That dessert or sandwich suddenly looks more appealing than your usual yogurt and berries.This isn't just about willpower.Your brain, short on rest, is pushing you toward quick, high-calorie fixes.Research shows that insufficient sleep disturbs hunger signals, weakens self-control and increases your risk of weight gain.Sleep inadequacy affects millions.More than one-third of U.S. adults regularly get less than seven hours of sleep per night. Nearly three-quarters of adolescents fall short of the recommended 8-10 hours sleep during the school week. First responders, including nurses, firefighters and emergency workers, are especially vulnerable due to night shifts and varying uncontrollable schedules. These patterns disturb the body's internal clock and are linked to increased appetite, poor eating habits and elevated risks for obesity and metabolic disease.Studies show that after just one night of sleep deprivation, reward-related areas such as the amygdala (杏仁核), a part of the brain that drives motivation and reward-seeking, become more reactive to inviting food.Your brain becomes more excited by junk food and less capable of resisting it. Participants in sleep deprivation studies not only rated high-calorie foods as more desirable but were also more likely to choose them, regardless of how hungry they actually felt.Sleep is as important as diet and exercise in maintaining a healthy weight. Fortunately, even a few nights of consistent, high-quality sleep can help rebalance key systems and start to reverse some of these effects. In a culture that glorifies hustle and late nights, sleep is often treated as optional. So the next time you find yourself reaching for junk food after a short night, recognize that your biology is reacting to stress. Sleep is your most powerful tool for appetite control, energy regulation and long-term health.32. What phenomenon does the author point out in paragraph 1 A. Sleep loss stimulates the brain for appetite. B. Staying up late can make people dizzy.C. High-calorie foods are more attractive. D. People are addicted to using mobile phones.33. Why are first responders more likely to suffer from sleep deprivation A. They bear expectation of the society. B. They have unhealthy lifestyles.C. They have demanding and shifting schedules. D. They have much pressure from the workload.34. Why is the brain more likely to shift into the reward mode after sleep insufficiency A. The brain reacts more quickly to the environment.B. Sleep loss changes how the brain evaluates food.C. The brain becomes more excited and unrealistic.D. Sleep loss changes how the body absorbs nutrients.35. Which would be the best title for the text A. How Sleep Loss Disturbs Body’s Internal ClockB. Why Quality Sleep Matters for Weight ManagementC. Sleep, Diet and Exercise: Keys to Healthy LivingD. Sleep Shortage: The Hidden Driver of Junk Food Cravings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终选项,选项中有两项为多余选项。Everybody gets angry, but out-of-control anger isn’t good for you or those around you. So here are five simple strategies to help you learn how to manage your anger:Relax. Breathe deeply from your stomach. 36 . Repeat it to yourself and visualize a relaxing time and experience.Change the way you think. When you’re angry, your thinking can get exaggerated. 37 . For instance, instead of telling yourself, “Oh, it’s terrible! Everything’s ruined,” tell yourself, “Is understandablethat I'm upset about it, but it’s not the end of the world.”38 . Statements like “This never works.” or “You’re always forgetting things.” will make you feel your anger is justified and there’s no way to solve the problem. They might upset people who might be willing to work with you to find a solution. Have better communication. Angry people tend to jump to conclusions. 39 . Listen carefully to what the other person is saying. And take your time before answering. Instead of saying the first thing that comes into your head, think carefully about what you want to say.Use humor. Psychologists say that highly angry people tend to think “things ought to go my way!”40 . So, when you feel that anger comes the next time, picture yourself as a king or queen, walking around, admired by everybody, and getting your own way in every situation. The more detail you can get into your imaginary scenes, the more likely it is to put a smile on your face. That will help you realize that the things you’re angry about are really not very important.Be careful with words like “never” or “always”Rushing to respond often leads to regretful wordsTaking a short walk can also ease tense feelingsTry replacing these thoughts with more reasonable onesThis kind of extreme thinking fuels anger unnecessarily“Silly humor” can help you get a more balanced perspectiveThen slowly repeat a calm word or phrase such as “take it easy”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,从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。I suffered from Asperger’s (阿斯伯格综合征) at my childhood.

Initially, it was just a little, but then, it seemed like overnight, my face was covered with it. I tried to hide it with my hair, but it just wouldn’t work.I was consumed with worry that my peers would make fun of me. I couldn’t concentrate in class, as my mind was constantly preoccupied with my appearance, causing my grades to slip sharply. I started to feel inferior (自卑的) to my classmates and even avoid interaction with them. I tried to get rid of the acne. I washed my face multiple times a day, using all sorts of acne creams I found. I also avoided snacks that might cause it. But all ended up in vain.One day, our school announced a sports day and the teacher asked us to form our own teams. As a sports enthusiast, I had been eagerly expecting it, but I was scared that no one would join me because of how I looked. Standing in front of the mirror, I kept imagining how my classmates would react when I asked them to team up with me. The fear of rejection held me back from approaching them.But then, Kim came to me, “Do you want to join us for the relay race I’ve seen you run before and you’ve got the speed. If you join us, we’ll have a good chance to win.” In disbelief, I managed to utter “Yes,” still feeling self-conscious but also incredibly grateful.I, together with another three classmates, signed up for the relay race. We trained for it and discussed strategies together, none paying attention to my acne. Because of my advantage in speed, I was even assigned to run the last leg, which was the most crucial part.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。Then came the long-awaited sports day.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________The experience was a turning point to my junior life.______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________南高高二期中英语答案听力: 1-5 CBBAB 6-10 CCAAC 11-15 CACBA 16-20 CABAB阅读:21-25 BDACB 26-30 BACBA 31-35 DACBD 36-40 GDABF完形填空 41-45:CACBD 46-50:ABCDB 51-55:DCABC语法填空56.dating 57. particularly 58. suspended 59.from 60.discovery61.where 62.have been played 63. which 64.to mark 65. a写作:第一节:A possible version:Dear Sir or Madam,I’m Li Hua, writing to apply for the Agony Aunt position in our school magazine, which I believe I would be a great fit for, since I’m really in tune with what my classmates are going through.First and foremost, as a fellow teenager, I know my peers quite well, so I can put forward constructive suggestions for their problems.

My palms were sweaty as I stood at the final position of the track. When the third runner approached, I grabbed the baton firmly and sprinted like the wind. Cheers erupted as I overtook two opponents. Crossing the finish line first, I saw my teammates rushing towards me with joyful screams. To my surprise, classmates patted my shoulder excitedly, their eyes shining with admiration instead of judgment. Kim hugged me, “You’re our superhero!” No one mentioned my acne — they only remembered my flying figure on the track.The experience was a turning point to my junior life. Gradually I realized people valued my abilities more than my appearance. I started raising my hand in class again and joined the school basketball team. Though acne still occasionally troubled me, I stopped hiding behind my hair. When a new student once asked about my skin, Kim immediately defended, “That’s just his warrior paint from saving our relay race!” We all laughed, and I finally understood true friendship sees beyond surfaces.听力(Text 1)M: So do all employees get a discount on store purchases W: Yes, we offer a ten percent discount.

Before we get started, I want to make an announcement. The quiz I had planned for today will have to wait until next Tuesday. I didn’t have time to get it ready, so you have a few extra days to study.Now, let’s get to today’s topic. Some of you may not like science, but you should at least respect it because it adds so much to our lives. Recently, I read about a newly created plastic that changes color when it’s stretched. How did the scientists dream up this idea They could never have done it without observing nature. While studying certain insects, the scientists found that the insects’ shells changed color when looked at from different angles. They immediately thought of ways to use that science to benefit humans. The scientists plan to use this plastic on food packages to tell us when our food goes bad and on our money to make it more difficult for criminals to copy. So when you’re walking to class each day, try to take some time to observe nature around you. You never know when you’ll have a bright idea that can change how we live. 展开更多...... 收起↑ 资源列表 期中音频.m4a 高2024级英语试题.docx 高二期中英语答案.docx
