海南省文昌中学2024-2025学年高二上学期第一次月考英语试题一、阅读理解Best spring destinations in TibetThe Qinghai-Tibet Plateau has long been an ideal and mysterious destination for visitors who are passionate about exploring remote lands. Here we recommend some of the best tourist destinations in Tibet.Peach Blossom Valley, NyingchiThe peach blossoms in Nyingchi have been dubbed as “the most beautiful peach flowers in the world”. The annual festival has become a signature tourism event on the plateau. Peach trees bloom depending on the altitude and climate, so visitors will have the chance to enjoy the blossoms.Ranwu LakeRanwu Lake is renowned for its tranquility (平静) and its purity of blueness. Scenery along the lakeside varies a good deal with grass, forest, autumn leaves, white waterfowl and snow mountains clearly reflected in the mirror-like water. Spring coming, a reflection of green trees dances on the lake and people feel like they are walking into a romantic dreamland.The Yarlung Zangbo River Grand CanyonThe Grand Canyon is the deepest canyon in the world. With a total length of about 500 kilometers, its altitude spans from 7,782 meters to 550 meters around the Yarlung Zangbo River Valley. Visitors can enjoy both the peach blossoms and the snow-capped mountains.Nanyi Valley Nanyi Valley is known as “the highest green mysterious place on Earth”. Surrounded by mountains and shrouded in clouds, Nanyi Valley is an ideal spring destination for visitors, where you can find peach and azalea blossoms everywhere.There are some other attractions. For more information, please click the following link /.1．If you are a festival lover, which destination will you choose?A．Nanyi ValleyB．Ranwu LakeC．The Yarlung Zangbo River Grand CanyonD．Peach Blossom Valley, Nyingchi2．What do Ranwu Lake and The Yarlung Zangbo River Grand Canyon have in common?A．Admiring snow mountains.B．Watching white waterfowl.C．Enjoying peach blossoms.D．Appreciating azalea flowers.3．Where is this text probably taken from?A．A book review B．A websiteC．A magazine D．A travel brochureI arrived home from work, my mind racing. I was scheduled to perform an experiment using a pricey piece of equipment, but I had spent the whole day worrying about the experiment which was on the top of my agenda (日程), and I amazingly longed to shut off my anxious thoughts. So after dinner, I made a cup of hot chocolate, stretched myself on my sofa, and opened a page. Almost instantly, my mind left behind the details of experimental design and stepped into a land of monsters, magic dust, and man-like bears comprising a wonderful world distinct (不同的) from my daily life. It was exactly what I needed.Growing up, I was virtually never a big fan of novels. My classmates would be crazy about the latest Harry Potter book, while my copy sat collecting dust on a shelf. Instead, I would choose to read through the reference books related to my academic fields for better grades. After I started graduate school, extracurricular reading didn’t appeal to me at all but I spent most of my time on campus digesting research papers and textbooks and my mind couldn’t handle processing fact-filled nonfiction books at home, too. So I knew that I needed to find a way to enjoy reading again.To help me stick with it, I made a New Year’s resolution: I would read two fiction books per month for the entire year. The result was an almost instant appreciation of fiction, along with many unexpected results including ones that have benefited my schoolwork.What surprised me the most was how much I learned. Some of the best books I read were historical fictional stories happening in a realistic historical setting. I learned about life in different countries, as well as struggles people there faced during difficult periods in their histories. Thebooks have helped me build sympathy and understanding, with an unexpected benefit: I’ve started to think more deeply about the diversity of issues in the scientific community and could serve it, heart and soul.4．What did the author do to wipe out the anxiety?A．He drowned it in chocolate.B．He conducted an experiment.C．He slept on the sofa leisurely.D．He escaped into a fantasy world.5．What was the author’s attitude towards reading in paragraph 2?A．Reading novels was not attractive to the author.B．Reading a good book was time well spent.C．He was too busy to take good care of his books.D．The Harry Potter book wasn’t as good as expected.6．How did the New Year’s resolution benefit the author?A．More sympathy went out to him.B．His moral values were strengthened.C．He learned much about religious diversity.D．He gained new insight into his academic fields.7．What’s the best title of the text?A．Reading: A Lifelong Hobby B．The Power of Research PapersC．Novels: Love at Second Sight D．The Benefits of History ReadingWhen you watch a great film, there’s always a great mix of everything you enjoy: Explosions! Exotic (异国的) locations! Amazing stunts (特技)! And all of it stars famous A-list actors. However, all that could soon be changed.Hollywood was rocked recently by an AI program called Sora. All you need to do is type in a description of what you want to watch, and it creates a video up to one minute long. This is possible because the programme has been fed thousands of hours of existing videos, searched through them for patterns, and then used this learning to create new content. As it develops, this technology could allow filmmakers to greatly expand their creativity. Simply give the computer program a script (脚本), tell it what actors you want, and it will create a movie for you. This will make it much cheaper to make films. AI might even help to create films tailored to personal tastesby analyzing viewing history and making a custom movie.Amazing developments in AI could fuel a new era of filmmaking. However, there are concerns. Many argue that AI can’t be truly creative, as humans are. AI expert Bernard Marr writes, “No matter how impressive a piece of computer-created artwork might be, it’s always built from blocks carved out of the data that’s used to train it.”AI actors could lead to a flood of poor quality, cheap films. As AI films copy and remix data from each other, researchers warn that this could lead to a “downward spiral”, where films become more similar and more boring over time.“Human emotion must always come first,” says Avatar director James Cameron. AI actors may never recreate the complexity (复杂) of emotions that humans can. They will probably stay trapped in the “uncanny valley” — the uncomfortable feeling we get when we see something that’s almost — but not quite — human.8．Why is Sora mentioned in the text?A．To explain the principles of AI filmmaking.B．To highlight AI’s impact on filmmakers’ creativity.C．To show how AI can change traditional filmmaking.D．To introduce an AI program for creating films.9．What is a possible concern about AI films?A．They may cause copyright issues.B．They may be much like each other.C．They may change the way humans enjoy films.D．They may not be as impressive as human-made films.10．How are people likely to feel about emotions created by AI actors?A．Awkward.B．Natural.C．Relaxed.D．Shocked. 11．What does the text mainly talk about?A．Sora’s impact on Hollywood.B．Creating your films with Sora.C．AI’s Strengths and weaknesses in filmmaking.D．Ensuring the quality of films with AI.Hibernation (冬眠) is a classic topic of science fiction. In movies such as 2001: A Space Odyssey, Alien, or Passengers, crew members are put into a state of sleep to take year-long journeys to space. Now a new study from Washington University has shown that human hibernation may soon become a reality.The research team carried out tests on rats — animals that do not naturally hibernate. They first identified a group of neurons (神经元) in a deep brain region, which were found to be related to controlling body temperature during hibernation. They showed that, in mice, these neurons could become more active using ultrasound (超声波), which was delivered through a helmet without causing an injury.When receiving the ultrasound, the mice showed a drop in body temperature of about 3°C, and their heart rates fell by about 47%. When the ultrasound system was switched off, they woke up again. The result was “surprising and fascinating”, said Hong Chen, a professor who led the work.Researchers are also trying to determine how to harness the power of hibernation to help humans. They believe that it could be key to deal with health conditions like heart disease, and Alzheimer’s. Furthermore, hibernation’s ability to slow aging, which was observed in bats, could benefit space exploration, enabling longer missions with less food requirements. Research in animals also suggests that bodies of hibernating astronauts might lose less bone and muscle, making them fit and ready to start challenging exploration soon after they wake up.The scientists now plan to look at how lowered body temperature might affect the cognitive (认知的) abilities of humans. “Our next experiments will test working memory in monkeys. This is important because while astronauts physically hibernate as they fly into deep space, their brain still needs to be working,” said Chen.12．How did researchers put rats into hibernation?A．By reducing their body temperature.B．By causing specific brain neurons to function.C．By putting a regular helmet on them.D．By using ultrasound through an operation.13．What does the underlined word “harness” in Paragraph 4 probably mean?A．Use.B．Challenge.C．Replace.D．Discover.14．What advantage might hibernation bring to humans?A．It improves people’s mental health.B．It predicts a variety of heart diseases.C．It helps astronauts keep physically fit.D．It enables astronauts to build up muscle.15．What’s the purpose of the last paragraph?A．To point out the significance of the study.B．To bring out the focus of follow-up studies.C．To discuss other factors affecting hibernation.D．To explain practical applications of the finding.Wherever you go, you’ll notice the plastic crisis faced by the planet. Many people are now seeking creative solutions to this problem. 16 You can do this by building a vertical garden with recycled plastic bottles-a brilliant idea which can be adapted to suit almost any household in any environment.An example from India shows how this inventive technique is truly changing lives.The Mehra family from Amritsar were locally hot news last June when they showed off the vertical garden they had created at their home. The family used over 175, 000 plastic bottles to create the garden, fixing the bottles to the outside walls of their home and filling them with over 33 varieties of plants. The plants are watered using a simple drip system. 1718 If you have a wall, you can have a vertical bottle garden. With space so limited around urban areas, this is a vital benefit, especially to urban and city-livers.If you struggle with ordinary gardening due to joint or muscle problems, vertical gardening can help you enjoy caring for plants without having to bend too much. 19 Just enjoying the lovely view of these vertical gardens is a positive thing in itself, but the act of setting up and caring for one will help to create inner balance and have further calming benefits in a stressful world.Whether you create your own small-scale vertical plastic garden at your home, or increasingly, whether large institutions get on board with the concept, every vertical garden created this way is recycling plastic which would otherwise be a pollutant, actively reducing localpollution. 20A．You don’t need a lot of space.B．Consequently, you feel a sense of your own worth.C．The key is, what can be used to replace plastic products?D．Incredibly, this has lowered the internal temperature of their home.E．Besides, interaction with plants has a positive effect on mental health.F．Additionally, vertical gardening offers advantages for physical health as well.G．What if we put waste plastic to a good use and enriched lives at the same time?二、完形填空Have you seen people who take pictures of food for more than 10 minutes before eating? How about those who beautify their selfie (自拍) so much that they can’t be 21 ? There must be one or more who 22 in your social media, sharing the best but the most unreal.Every time we went to a restaurant, my friend Ella would not take a 23 until all the dishes we 24 were on the table. Then, she would spend five minutes setting the dishes in a seemingly random (随意的) but in fact 25 order. Then the most important part: taking pictures. After that, she would choose one of the 26 and click in the filter (滤镜) app. The food 27 looked 10 times more delicious than it really was, but we had no 28 to really enjoy it — it all went cold. Actually, Ella’s real life is much less elegant (优雅的). For example, she 29 to wash the dishes, so she leaves them in the sink for days.Many people 30 others’ opinions to such an extent that they try too hard to please others. They find it hard to be 31 and to accept themselves, and thus they are afraid to show their real life on social media. What they are trying to prove is exactly what they32 in reality. But this will not bring any change to reality, as they still follow the same old33 of life.If they really want an elegant life, they should put more 34 into achieving it. Being more confident, 35 themselves and trying their best to be better is much more meaningful than beautifying their life on social media.21．A．ignored B．admired C．recognised D．defeated22．A．exist B．survive C．flood D．spot 23．A．bow B．break C．breath D．bite 24．A．ordered B．served C．offered D．prepared 25．A．messy B．arranged C．flexible D．correct 26．A．dishes B．restaurants C．pictures D．tables 27．A．normally B．hardly C．eventually D．originally 28．A．chance B．choice C．excuse D．reason 29．A．desires B．intends C．attempts D．hates 30．A．refer to B．care about C．insist on D．turn to 31．A．independent B．generous C．responsible D．confident 32．A．obtain B．admit C．lack D．hide 33．A．advice B．commitment C．virtue D．pattern 34．A．effort B．effect C．success D．money 35．A．pursuing B．accepting C．persuading D．rejecting三、语法填空阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
