You can move your ugly car up now!” The silver-haired driver behind me in a fancy truck rudely yelled at me. Without much thought, I yelled back at the man, “What? Are you in a rush or something?”I was waiting in line at the drive-through to order our breakfast on a Sunday morning. There were only 12 inches or so between me and the car in front of me. There were also three additional cars in front of that one. We were getting nowhere fast. What was he hoping to gain by yelling at me?I wanted to let my own anger go after this ridiculous exchange. But the more I thought about it, the angrier I got. I was angry that he yelled at a mother in front of two kids. My daughter and my son were both confused and saddened by what they had just witnessed. We were on our way to a soccer tournament, and we had a bonus day free from school and work. Probably, there was nothing in the world to be upset about. Then this man let his anger out.I told my kids I was so mad that I had to roll my window up so that I wouldn’t keep yelling at this guy. Then, I stopped and looked back. I had moved up the 12 or so inches at his “suggestion”, while he hadn’t moved an inch. Suddenly, I felt sympathy for him. He must have been suffering in some way. As my kids and I slowly made our way to the pick-up window to pay for our order, I had an idea.“I heard how rude that man was to you, and I wanted to apologize to you for having to put up with that. He isn’t worth paying for,” the cashier said to me. “My kids support me in doing that,”I answered the cashier, adding that hate cannot drive out hate.4．Why was the driver angry with the author?A．Her car cut in.B．She screamed at him.C．She held up his truck.D．Her car stopped suddenly.5．What does the author mainly tell us in paragraph 3?A．What her kids’ reaction was.B．Why her anger kept growing.C．How she calmed herself down.D．Why she ordered the breakfast.6．What was the author’s final decision?A．She taught her kids a lesson.B．She apologized to the driver.C．She paid for the driver’s food.D．She gave the cashier some advice. 7．What does the author intend to convey in the text?A．Respond to hate with kindness.B．Deal with a man as he deals with you.C．Put distance between your car and another.D．Never go to the drive-through at rush hours.What comes into your mind when you think of British food? Probably fish and chips, or a Sunday dinner of meat and two vegetables. But is British food really so uninteresting? Even though Britain has a reputation for less-than-impressive cuisine, it is producing more top class chefs who appear frequently on our television screens and whose recipe books frequently top the best seller lists.It’s thanks to these TV chefs rather than any advertising campaign that Britons are turning away from meat-and-two-veg and ready-made meals and becoming more adventurous in their cooking habits. It is recently reported that the number of those sticking to a traditional diet is slowly declining and around half of Britain’s consumers would like to change or improve their cooking in some way. There has been a rise in the number of students applying for food courses at UK universities and colleges. It seems that TV programmes have helped change what people think about cooking.According to a new study from market analysts, 1 in 5 Britons say that watching cookery programmes on TV has encouraged them to try different food. Almost one third say they now use a wider variety of ingredients (配料) than they used to, and just under 1 in 4 say they now buy better quality ingredients than before. One in four adults say that TV chefs have made them much more confident about expanding their cookery knowledge and skills, and young people are also getting more interested in cooking. The UK’s obsession (痴迷) with food is reflected through television scheduling. Cookery shows and documentaries about food are broadcast more oftenthan before. With an increasing number of male chefs on TV, it’s no longer “uncool” for boys to like cooking.8．What do people usually think of British food?A．It is simple and plain.B．It is rich in nutrition.C．It lacks authentic tastes.D．It deserves a high reputation.9．Which best describes cookery programme on British TV?A．Authoritative.B．Creative.C．Profitable.D．Influential. 10．Which is the percentage of the people using more diverse ingredients now?A．20%.B．24%.C．25%.D．33%.11．What might the author continue talking about?A．The art of cooking in other countries.B．Male chefs on TV programmes.C．Table manners in the UK.D．Studies of big eaters.A new study suggests that smoke from wildfires can change how clouds store water and could lead to less rainfall. The research comes as western parts of the United States are currently experiencing drought conditions after several years of intense wildfire activity.Clouds contain a collection of water droplets (微滴) that form from vapor in the atmosphere. When these droplets condense (凝结) onto each other within a cloud，they become heavier and eventually fall as rain. But the water condensation process requires a solid substance for the vapor to attach to. Different kinds of particles rising up from the Earth’s surface can reach clouds and make this process possible.The new study found that smoke from wildfires contains small particles that affect the way droplets form in clouds. The main effect was the number of water droplets formed. The team reported that smoky clouds contained about five times the number of droplets as non-smoky clouds. But data also showed that the droplets in smoky clouds were much smaller, about half the size of those in the clouds without wildfire smoke.It is that size difference, the researchers say, that could reduce the amount of rainfall. This is because small droplets are less likely to grow and eventually fall to the ground as rain. “Because of their small droplet sizes, these smoky clouds are expected to reflect more light and produce less rain than clouds in clean air,” the study states.The findings could mean that active wildfire seasons in the western U. S. may in fact lead to less rain and more drought, the researchers said. “We were surprised at how effective these primarily organic particles were at forming cloud droplets and what large impacts they had on the microphysics (微观物理) of the clouds,” said Cynthia Twohy, leader of the new study.Twohy also noted that different kinds of clouds behave differently. The current study examined changes in small cumulus clouds. Other kinds that sit much higher in the atmosphere can cause heavy storms, she said. Twohy added, “I am hoping these results will lead to detailed regional modeling studies that will help us understand the actual impact of smoke on clouds and climate.”12．Why did the researchers conduct the study?A．They aren’t sure how water droplets form from vapor.B．There is a great climate change in America.C．The US has serious drought after wildfires.D．They wonder how smoky clouds appear.13．What is a characteristic of smoky clouds?A．They tend to reflect more light.B．They often have lower temperatures than others.C．They contain more droplets which are larger in size.D．They have fewer particles for the vapor to attach to.14．What could smoky clouds lead to according to the text?A．Less rainfall.B．Much cooler weather.C．Fewer windy days.D．More storms.15．What is the main idea of the text?A．There are many reasons for the US drought.B．Wildfire smoke can make clouds produce less rain.C．Organic particles play an important role in forming clouds.D．Humans have to face the serious consequences of wildfires.We eat in our cars, at our desks, on the go, and in front of the TV. We eat takeout, packaged and prepared meals. Why? Because it fits our notenoughtimeintheday lifestyles.16 Well, I’m certainly not the first one to think it or say it, but we all need to slow down.Consumer trends around the globe show that over the past three decades people are purchasing more prepared foods at groceries and eating out more than ever before. It’s predicted that we’ll spend more at restaurants in the coming years. 17 However, we’re getting less healthy.While debates can be seen in different media over the food industry’s contribution to our growing waistlines and our health problems, the bottom line is this：18 We can choose to eat a fastfood lunch on the go. We can throw a frozen meal in the microwave and call it dinner. We can eat without thinking, in front of the tube, at our computers, and while driving a car.19 Studies have shown meaningful links between family meals and kids’ mental and physical wellbeing. Eating sensibly doesn’t take much time or money, but it does require you to make a conscious decision to do so. Wrapped up in endless work, appointments and social activities, we often fail to enjoy a relaxing meal with our families.While it can be a challenge to always put healthy eating first, just do your best. Remember that the food you eat has a more significant effect on your health, weight and wellbeing than almost any other activities you do. 20 Every meal made at home — even just once or twice a week — is a step closer to a healthier body and a slower eating style.A．Lunch is the biggest calorie intake when it comes to eating out.B．Treat it with the importance that it deserves, but start small.C．Our food matches our lives.D．Purchase food locally and skip as many packaged items as you can.E．What we eat, where we eat and how we eat are all under our control.F．We’re consuming an increasing number of calories.G．We can devote an hour of the day to enjoying a meal with our families.二、完形填空When I was 18, my older brother bought me my first mountain bike.

A 17-year-old student who wants to take a part-time job.Zea Tongeman, a 14-year-old student, who is crazy about the Internet, applied technology to create an application that encourages people to recycle rubbish while having fun.Zea was really inspired when she attended "Little Miss Geek Day", an event that aims at making technology more accessible and appealing to young women and inspiring them to consider technology careers. Soon after, she entered "Apps for Good", a competition that encourages students to create positive change through technology. Teaming up with her friend, Jordan Stirbu, she laid the foundations for the "Jazzy Recycling".The "Jazzy Recycling" application is designed to encourage young people to recycle rubbish more, which wins the favor of the youth. It turns waste disposal into a game and helps you find places to recycle it. Then you scan what you need to recycle, share it, and get rewards such as shopping vouchers(代币券) and games to be unlocked for what you have recycled.Tapping into the teen enthusiasm for sharing every little aspect of their daily life on social media, recycling efforts can be shared too as a fun game among friends, which can make more people take part in recycling activities.Zea explains why she is addicted to the Internet and how technology has changed her ideas about the future, "I used to think technology was just fixing computers and using smartphones; I have become very tired of just using what is available. I have discoveredanother side of it and that I can make technology of my own."In fact, Zea Tongeman has taken the idea of recycling seriously and hopes all her fellow human beings would give it a serious thought. This teen girl from the United Kingdom has made use of computer programming to create her own app that would encourage people to go recycling for a better world.4、What is "Little Miss Geek Day" intended to do?A.To inspire students to go recyclingB.To encourage students to create more.C.To introduce some famous young ladies.D.To get girls interested and involved in technology.5、How does the "Jazzy Recycling" application appeal to the young?A.It combines recycling with fun.B.It offers money to those who recycle rubbish.C.It raises their awareness of waste disposal.D.It provides varieties of convenient services.6、Which of the f following best describes Zea Tongeman?A.Considerate.B.Generous.C.Creative.D.Modest.7、What can we learn from Tongeman's story?A.Teenagers have a talent for creating apps.B.Technology plays a significant role in education.petitions inspire e teenagers to achieve success.D.Youngsters can make a difference in their own ways.Elephants are the largest land mammals on Earth, and understanding them better could lead to some incredibly large breakthroughs in science. Researchers are doing a deep-dive study on elephant trunks, with the aim of improving the future of robotics.Elephants' trunks are both delicate and strong—they are capable of grasping a single leaf but can also carry nearly 600 pounds. And scientists argue that these multifunctional trunks—called proboscis—are incredible inspiration for the next generation of bio-inspired(仿生) robots."Classical robots are extremely good for performing a specific task for which they've been designed. If you want that robot to do something a little different, it will fail," said Michel Milinkovitch, a professor of the physics of biology at the University of Geneva.In new research, scientists explained how elephants can move their trunks with almost unlimited degrees of freedom, combining about 20 basic movements to carry out morecomplicated movements. "Elephants have sort of a toolkit of simple movements, and they can combine these simple movements to complex trajectories(轨迹)," Milinkovitch said. "They can adapt to the object you give them." The study also found that elephants can form "pseudo-joints" with their trunks, similar to the structure of a human elbow(肘) and wrist."It's also a feeling of wonder just looking at these amazing creatures," Milinkovitch said, noting that African forest elephants and African savanna elephants are endangered species. "We also hope to increase awareness of the conservation of this very unique animal," he said. "There are a lot of principles that we can learn from nature; it's not just there for our happy life—it is really an incredible source of engineering principles."8、What is the inspiration of elephants' trunks for bio-inspired robots?A. They are too strong to break easily.B. They are adaptable to different tasks.C.They are long enough to carry out tasks.D. They are good at performing simple tasks.9、What can be inferred from the last paragraph?A. Humans should treasure the happy life.B. Humans should apply engineering principles.C. Elephants in the world are on the edge of extinction.D. Raising awareness of animal conservation is significant.10、Where is the text probably from?A. A science magazine.B.A news review.C. An advertisement.D. A tourist brochure.11、What is a suitable title for the text?A. Time to Protect ElephantsB. Elephants' Trunks and RoboticsC. What Strange Elephants' TrunksD. Inspiration for Scientific BreakthroughFor generations, depression has been seen as an illness, disorder or even weakness. Such an idea makes sense because depression causes suffering and even death. But what if we've got it all wrong?The common wisdom is that depression starts in the mind with abnormal thinking. That leads to symptoms like headaches, stomachaches, or tiredness. Now, models like the Polyvagal Theory suggest that we've got it backward. It's the body that detects danger and initiates a defense strategy meant to help us survive. That biological strategy is called immobilization, and it demonstrates in the mind and the body with a set of symptoms we calldepression.When we think of depression as unnecessary suffering, we are telling people with depression that they are not part of the group, they are not right and they don't belong. That robs them of hope. But when we begin to understand that depression, at least initially, happens for a good reason we lift the shame. Instead, people with depression are courageous survivors, not damaged sick people.The autonomic nervous system(ANS) is constantly scanning our internal and external environment for signs of danger. If our ANS detects a threat or even a simple lack of safety, its next strategy is the fight or flight response, which we often feel as anxiety. Sometimes the threat is so bad or goes on for so long, that the nervous system decides there is no way to fight or to flee. At that point, there is only one option left: immobilization.The immobilization response is the original biological defense in higher animals. It dulls pain and makes us feel disconnected. Think of some reptiles(爬行动物), which shut down their bodies to avoid cold temperatures and the lack of food and water. In humans, people often describe feeling "out of their bodies" during extremely unpleasant events, which has a defensive effect of reducing the emotional shock. This is important because some things are so terrible, we don't want people to be fully present when they happen. What incredible capacity of our biology to find a way in hard times!12、Why does the author mention the Polyvagal Theory?A. To offer a standard for identifying depression.B. To raise people's awareness of mental problems.C. To make sense of how depression affects people.D. To correct a commonly held idea about depression.13、What can we infer from Paragraph 3?A. Depression can bring people in crisis hope.B. People may feel it wrong to have depression.C.Depression is an unnecessary human emotion.D. People often feel proud of fighting depression.14、What is "immobilization" in the text?A. Building up anxiety.B. Rising to challenges.C. Shutting down action.D. Pulling through a crisis.15、In which order does our body react to an extremely unpleasant situation?①seek to work out solutions②become aware of a threat③experience emotional shock④start defensive disconnectionA.②③④①B.④②①③C.②①③④D.④①②③二、七选五16、 Procrastination (拖延症) is a common problem we face, which harms not only our performance but also our self-confidence. ①______. So, here we go.● Plan in advanceIf you don’t plan your day, you will find it difficult to be productive and get more done.

梅河口市第五中学2023-2024学年高二下学期开学考试英语试卷(含答案)
梅河口市第五中学2023-2024学年高二下学期开学考试英语试卷学校：___________姓名：___________班级：___________考号：___________一、阅读理解Bristol Old VicWhen the Theatre Royal (now Bristol Old Vic) was built, electricity hadn’t been discovered. For over 250 years the people who have owned, worked inside and visited the theatre have kept records about their activity. These are kept safe at the University of Bristol Theatre Collection, and you’ll discover a range of documents which record the history of the theatre, from its foundation in 1764 up until the present day. Here are some of them. BEGINNINGIn 1764 businessmen Alexander Edgar and Thomas Symons suggested building a new theatre between Baldwin Street and the back of Coopers’ Hall in King Street. The estimated cost was f2, 000 to be split among 40 subscribers, but the building work cost more than expected. Owning shares allowed them to influence decisions about the theatre.SILVER TICKETEach of the original Bristol Old Vic shareholders was given a silver ticket that promised sight of any performance held at the theatre. As the holders were clever businessmen, they insisted that the silver tickets could be loaned or traded. This enabled them to make some extra money but made it extremely difficult for the theatre managers to keep track of who was allowed to see shows for free.250TH BIRTHDAYIn May 2016, the theatre celebrated its 250th birthday! As the oldest continuously-working theatre in the English-speaking world, it deserved a proper party, so Bristol-based Limbic Cinema was hired to create a film of the theatre’s historical highlights which was projected (放映) onto the theatre itself.1．Where can you find the three mentioned documents?A. At Baldwin Street.B. At Coopers’ Hall in King Street.C. At Bristol-based Limbic Cinema.D. At the University of Bristol Theatre Collection.2．How was the theatre’s 250th birthday celebrated?A. By creating a film about its history.B. By building Bristol-based Limbic Cinema.C. By releasing silver ticket in memory of the birthday.D. By making a film projected in theatres across England.3．What’s the purpose of the text?A. To compare the theatre and others.B. To change people’s view on Bristol Old Vic.C. To introduce some information of Bristol Old Vic.D. To recommend a movie related to the theatre.For many runners, a marathon can often be a challenge — but sometimes what gets a runner through the tough 26.2 miles is looking out into the crowd and seeing his or her loved one holding up a sign and shouting words of encouragement. For one mom, though, her loved one was a bit more hands-on.While running the REVEL Big Cottonwood Marathon in Salt Lake City, Courtney Rich, a self-taught baker and mother of two, was beginning to run out of energy just yards from the end when she was suddenly joined by her 10-year-old daughter, Avery.The touching moment, caught on video and posted on social media, shows Avery running to her mother’s side to support her as she approached the end of the race. Rich’s face lit up when Avery joined her and helped her cross the finish line.Rich later said in the video’s caption that being joined by her daughter to finish the race was “a moment I hope neither of us ever forget”. Rich said that her daughter could tell she was struggling after a phone call near the end of the race. “She knew I had struggled the last few miles,” Rich said. “She saw tears in my eyes when I called on mile 24.”In the video, Rich’s facial expression changes from tiredness to a smile after seeing her daughter emerge from the crowd to join her. Then, Rich and her daughter ran hand-in-hand to the finish line. “Nothing could have prepared me for the moment my 10-year-old daughter would jump out of the crowd and run with me to the finish line,” she said. When the race was done, the two hugged each other at the finish line. The video ends with a final caption, “And then she just held me. She held me.”In the past, the REVEL Big Cottonwood Marathon has had other memorable moments of mothers caring for their children, but perhaps not as hands-on as this one.4．What happened to Rich when she was coming to the finish line?A. She fell down all of a sudden.B. She was far behind others.C. She felt herself struggling.D. She was interrupted by Avery.5．How did Avery react to the accident?A. She helped Rich run to the finish line.B. She tried to call for help at once.C. She ran the rest in place of Rich.D. She shouted encouraging words to Rich.6．How did Rich feel about Avery’s response?A. Doubtful.B. Content.C. Concerned.D. Expected.7．What can be the best title for the text?A. A Mother Would Never Give Up On Her Marathon DreamB. A Mother Encouraged Her Daughter To Pursue Her DreamC. A Daughter Got Involved In Her Mother’s Race By MistakeD. A Daughter Cheered For Her Mother By Joining In Her RaceWithin the beautiful scenery of Wisconsin’s Lake Chippewa lies a natural wonder that is a unique challenge for the local community. This hidden wonder is exactly a giant floating island. The island, made up of plants and trees, sometimes floats around the lake, causing a major inconvenience by blocking (阻塞) an important bridge. Later, the local people came up with a solution to this problem. Every year, local boat owners work together and push the island away from the bridge.Lake Chippewa was born in 1923 when a vast bog (沼泽) was changed through flooding. Soon after that, many of the dark bogs started rising to the surface and became perfect growing places for plants, with seeds carried by wind and wild birds to this floating place. Over the years, these bogs have grown plants and trees and turned into full islands. As time goes by, plants take root, and the oldest islands even have trees that act as sails (船帆) when the wind blows, moving the entire floating island around the lake.Although the years-old floating island does not relocate (重新迁移) so often, when it does, it causes trouble for the community by blocking the important bridge that serves as the only passage between the lake’s East and West sides. The only solution is to gather a group of boats, and not just one or two, but dozens of boats working together to push the island away. “It takes a community’s effort, and you must have the winds at your back to push them in,” said a resident. Moving the island also requires precision (精确), as just relocating it a short distance may result in its return within days.Some people have suggested destroying the floating islands to get rid of the problem. However, the big bog in Lake Chippewa has been around for many years, and during thattime a variety of animal and plant species have made it their home. Therefore, local government advises they be dealt with in a way that won’t do harm to wildlife, paying more attention to the fine-drawn balance between human convenience and environmental protection. The annual tradition of relocating Lake Chippewa’s floating island is evidence to the coexistence of man and nature, a heartwarming display of community unity, and a reminder of the importance of preserving the unique areas that enrich our world.8．What does the underlined word “solution” in paragraph 1 refer to?A. Building a new bridge.B. Moving the floating island away.C. Transforming the vast bog.D. Rebuilding the local community.9．What can we know from paragraph 2?A. The formation of the floating island.B. The history of flooding in Lake Chippewa.C. The varieties of species in Lake Chippewa.D. The impact of the wind on the floating island.10．Which of the following statements is true about the relocation work from paragraph 3?A. It is usually finished within days.B. It is a must in cooperation and precision.C. It can only be carried out during windless days.D. It greatly disturbs the community residents’ lives.11．Why has the local government refused to destroy the island?A. To save costs for local people.B. To ensure the safety of residents.C. To improve the bond between communities.D. To protect the wildlife species on the island.Like so many other good things in life, sleep is best at a right length. A multi-year study of older adults found that both short and long sleepers experienced greater cognitive (认知的) decline than people who slept a proper amount, even when the effects of early Alzheimer's disease were taken into account.“Our study suggests that there is a middle range, or ‘sweet spot’, for total sleep time where cognitive performance is stable over time. Short and long sleep time is associated with worse cognitive performance,” said first author Brendan Lucey, an associate professor of the Washington University Sleep Medicine Center. “An unanswered question is if we can intervene to improve sleep, would that have a positive effect on their cognitive performanceso they no longer decline? We need more further data to answer this question.”Lucey and colleagues turned to volunteers who participate in Alzheimer's studies through the university's Charles F. and Joanne Knight Alzheimer Disease Research Center. Such volunteers experienced annual clinical and cognitive assessments, and provided a blood sample to be tested. For this study, each participant slept with a tiny EEG monitor attached to their heads for four to six nights to measure their brain activities during sleep.The researchers found a U-shaped relationship between sleep and cognitive decline. Overall, cognitive scores declined for the groups that slept less than 4.5 or more than 6.5 hours per night while scores stayed stable for those in the middle of the range.The U-shaped relationship held true for measures of specific sleep phases, including rapid-eye movement (REM), or dreaming sleep and non-REM sleep. Moreover, the same is true even after adjusting for factors that can affect both sleep and cognition, such as age, sex, levels of Alzheimer's proteins. “It was particularly interesting to see that not only those with short amounts of sleep but also those with long amounts of sleep had more cognitive decline,” said Professor Be au M. Ances.“Each person's sleep needs are unique, and people who wake up feeling rested on short or long sleep schedules should not feel forced to change their habits,” said co-senior author David Holtzman, MD. “But those who are not sleeping well should be aware that sleep problems often can be treated.”12．What's the passage mainly about?A. The effects of Alzheimer's disease.B. The benefits of best sleep.C. The influence of sleep time on cognition.D. The good things in life.13．According to the passage, which sleep time is suitable?A. 4 hours.B. 6 hours.C. 7 hours.D. 7. 5 hours.14．What can we know about U-shaped relationship?A. The sleep time has no connection with cognitive scores.B. The longer sleep time is, the higher cognitive scores are.C. Cognition is related to different sleep phases.D. It is not effective when age, sex, and so on are considered.15．What does David Holtzman's words imply?A. Quality of sleep is the key.B. Long time sleepers do not have cognitive decline.C. Short sleep schedules must change their habits.D. Both long time and shot time sleepers have sleep problems.二、七选五16．When gardeners grow varieties of plants in their beautiful gardens, they are happy to see beneficial insects like bees and butterflies surrounding the flowers. But as they take a closer look, they may find some plants are covered in black dots and filled with harmful insects or pests. Some gardeners may immediately reach for chemicals. ①_________ Although it may stop the insect problem, it will also threaten bees and butterflies which help the plants reproduce.If you are wise gardeners, you should first take preventive measures to control the harmful insects. ② _________ Only when there are too many harmful insects, should pest control be considered. The first defense should always be the safest method available. PreventionAs a rule, prevention is the best treatment. Inspect plants closely, including their leaves, before buying them from the store. ③ _________When planting, space plants out to permit them to grow to their full size. Plants too close together can breed harmful organisms, like bacteria.④ _________ They invite pests if permitted to remain on the ground. When you do see pests, wash them away. Use rubbing alcohol to remove some insects, or pick them off the plants.PesticidesIf you decide a pesticide is necessary, choose it carefully and follow the directions and warnings on the product. Avoid using pesticides in extreme heat, on windy days, or when the plants are wet. ⑤ _________ At the time, beneficial insects are inactive. You can consider removing flowers from the plants to lessen the risk that beneficial insects will come in contact with the pesticides.A. But this is not wise.B. In most cases, chemicals don’t help.C. Treat the plants early in the morning or at night.D. Also do remember the plants need nutrition and care.E. Keep your garden free of fallen leaves, fruits and other wastes.F. Do not bring any plants home that show signs of disease or pests.G. The process starts with the idea that having some pests is acceptable.三、完形填空（15空）Margaret Thompson and her husband, Kenneth, stretched their legs together on walking holidays in Switzerland.
