山西省吕梁市部分学校2024-2025学年高二上学期9月月考英语试卷一、阅读理解Want to see the world? Each year, TIME magazine makes a list of the World’s Greatest Places, which is provided by our readers. They will take us from cities to wilderness, and from tiny villages to faraway islands. Here are some of the best ones.Culture TripRapa Nui is an island in the Pacific Ocean. It’s also known as Easter Island. It’s famous for the massive and mysterious sculptures(雕像) made by the Rapa Nui people, who arrived about 1,200 years ago. The spirit of Hotu Matu’a, their early king, is said to have become a sea turtle.—By Johanna Read Lively SpotThe Galápagos Islands are located off the coast of Ecuador in South America. They are some of the most biodiverse places on Earth. Recently, marine-life protections were expanded in the area, limiting fishing and cresting safe paths for animals to travel through.—By Karen Catchpole Ancient PastAlentejo is a rural part of Portugal in Europe. It is covered with forests and olive groves. There are ancient cities, too. A museum in Estremoz shows off traditional tiles. In Esperanca, hikers can see eagles and vultures, plus 5,000-year-old cave paintings.—By Robin Catalano Bike It!Bogotá is the capital of Colombia in South America. It’s the perfect place for a bike ride. The city has taken steps to reduce pollution. It has more than 350 miles of bike paths. The city also has a bike share program, which will provide bicycles that people with disabilities can use.—By Kate Crittenden 1.What can people do on Rapa Nui?A.Meet Hotu Matu’a.B.Visit a museum.C.Enjoy sculptures.D.See eagles.2.Who recommends the Galápagos Islands?A.Johanna Read.B.Karen Catchpole.C.Robin Catalano.D.Kate Crittenden.3.Which place best suits people who like riding bikes?A.Estremoz.B.Alentejo.C.Esperanca.D.Bogotá.Finnish Lapland, in the far north of Europe, is home to some 180,000 people and around 200,000 reindeer (驯鹿). The animals live wild but each one has an owner, identified by a mark on its ear. Anne Ollila, 50, one of 4,000 such owners, works in the Finnish part of this region with her husband and two adult sons and their families. They farm the animals mainly for meat, but reindeer tourism has also become an important source of income.Ollila lives 80 kilometres inside the Arctic Circle, an hour from Lapland’s capital city, Rovaniemi, and seven kilometres from her nearest neighbour. Summer days — when the reindeer raisers earmark newborn reindeer — are long and in June the sun never sets. At that time Ollila sleeps during the day and walks up to 20 kilometres a night through the forest, making the most of the cooler temperatures to do her work but having to endure large groups of insects along the way.In deepest winter, there is little daylight. Many grasslands are frozen and the reindeer move into the forest for protection against wolves and golden eagles — the birds can kill an adult reindeer.Ollila and her family offer tourists reindeer experiences through their company Reindeer Journey. Visitors can get close to the animals in the wild or at their farm, watching them being trained to pull sledges (雪橇) or take a sleigh ride.“Reindeer are very smart animals,” Ollila says. “They have different personalities, and some are very funny.” One of her favourites is Rocky, named after the movie boxing legend. “He’s very curious and always in trouble,” she says. “He once got himself stuck in tree branches and had to be lifted out, and he has been known to walk off with his owners’ drying underwear.”Ollila gave up her job as a sociology researcher at the University of Lapland in 2010 to devote herself to raising reindeer. “I love the environment, the animals and the freedom,” she says. “Also, I have a sense of belonging to something bigger than me, to a way of life through thegenerations.”4.What does the underlined word “endure” in paragraph 2 mean?A.Go away with.B.Catch up with.C.Look forward to.D.Put up with.5.Why do the reindeer move into the forest in winter according to the text?A.To get earmarked.B.To find their owners.C.To protect themselves.D.To avoid cold temperatures.6.What does Ollila think of Rocky?A.He is foolish.B.He is a troublemaker.C.He is interested in planting trees.D.He is a famous filmmaker.7.What can we infer about Ollila from the last paragraph?A.She has a deep affection for nature.B.She has long been tired of raising reindeer.C.She has been a sociology researcher since 2010.D.She had no chance to receive a college education.Over the years, movies and books have used tornadoes to sweep their characters off to magical lands, to destroy entire cities, or to defeat a superhero’s dangerous super villain (恶棍). All of these tornadoes have one thing in common: They are incredibly powerful. They can have wind speeds over 300 miles per hour (mph), grow over a mile wide, and travel over 50 miles. They are incredibly dangerous and should be avoided at all costs.Scientists can’t go inside tornadoes, which means that they are extremely hard to research. As a result, we know surprisingly little about them. In order to tell how powerful a tornado is, scientists look at how much destruction it causes. Scientists then rank the tornado on the Enhanced Fujita Scale (级别) (EF-Scale), which ranges from EF0 to EF5. For example, a tornado that only damages trees but doesn’t significantly damage buildings would be rated EFO with wind speeds between 65 and 85 mph. A tornado that blows away buildings and tears up sidewalks, on the other hand, would be rated EF5 with wind speeds over 200 mph.The most powerful tornado in United States history occurred near Oklahoma City in1999. It had wind speeds over 310 mph, the highest wind speed ever recorded on Earth. A tornado withwind speeds that high can not only pick up and throw automobiles, but also knock over trains and tear up roadways.Luckily for anyone living in an area that experiences the occasional tornadoes, they usually only last one to ten minutes. More powerful tornadoes can last over an hour in the right conditions, but they are very rare.If you find yourself experiencing a tornado, find a safe place inside, like an interior hall, basement or closet. Stay away from windows and heavy objects that could fall on you, and lie on your stomach with your hands protecting the back of your head. Having a tornado emergency plan is extremely important as tornadoes can appear very quickly. Make sure to listen to the radio or television to stay updated on serious weather patterns in your area.8.Which of the following is probably the wind speed of an EF4 tornado?A.65 mph.B.85 mph.C.200 mph.D.310 mph.9.What can we learn from the example given in paragraph 3?A.Tornadoes can do great harm.B.American cars need developing.C.Oklahoma City had no trains in 1999.D.The strongest tornado occurred in the UK. 10.What is the last paragraph mainly about?A.What a tornado is.B.How a tornado forms.C.Tips to survive a tornado.D.How to recognize a tornado.11.Where is the text most probably taken from?A.A guidebook to the USA.B.An introduction to a historical book.C.A review of famous movies.D.An article on natural disasters.When Adele released (发行) her 2011 single Someone Like You, this bittersweet song is popular with millions worldwide. More than a decade later, it remains one of her most popular songs. Her artistry, as well as that of many others who have mastered the art of making listeners feel moved with slow and emotional beats, has a way of managing the emotional pain of heartbreak and loss.Listening to favorite songs could also reduce people’s feelings of pain, according to a new study published in the journal Frontiers in Pain Research. And the most effective pain relievers were found to be sad songs detailing bittersweet and emotional experiences.“It doesn’t take the place of medicine when you have a headache, but music can help reduce your pain,” said Patrick Stroman, a professor at Queen’s University in Kingston, Ontario. He didn’t join in the study. “Unlike other medications,” he noted, “there is no side effect or risk in listening to music (just keep the volume at a reasonable level).”The small study invited 63 young adults to bring one of their favorite songs. The researchers also had the young adults pick one of seven songs that the team considered relaxing and were unfamiliar to the study participants. All the while, the researchers stuck a hot object — similar to the pain of a boiling hot teacup on the participants’ skin — to their left inner forearms. When rating their experiences, people were more likely to report feeling less pain when listening to their favorite songs compared with hearing the unfamiliar relaxing songs.With millions of songs available, one person’s favorite song is likely not the same as another. After interviewing the participants about the song they brought and their rating of pain, the researchers found people who listened to bittersweet and moving songs felt less pain than when they listened to songs with calming or cheerful themes (主题).“It’s a very cool result,” said lead study author Darius Valevicius, a doctoral student of neurosciences at the University of Montreal. “I think it’s why I myself and probably many people choose to listen to bittersweet or even spiritual music.”12.Why does the author mention Adele in the first paragraph?A.To reach a conclusion.B.To lead in the topic.C.To offer a suggestion.D.To provide the background.13.What is Stroman’s attitude to the effect of listening to music?A.Doubtful.B.Positive.C.Unclear.D.Unconcerned. 14.What did the participants do in the new study?A.They reported their feelings of pain.B.They interviewed many musicians.C.They made various kinds of teacups.D.They picked out the music they don't like. 15.Which is the most suitable title for the text?A.When Is the Best Time to Listen to Music?B.How Do You Create Popular Songs Quickly?C.The Best Way to Reduce Pain Might Be to Write MusicD.Certain Types of Music Could Help You Feel Less PainWhen we are kids, we laugh a lot. But as we become adults, it is much more difficult to laugh so easily. Do you laugh too little in your life? Do you remember how you used to laugh before, as a child?16 . It’s a great way to relax, not just on a purely emotional level, but also physically. It can reduce our blood pressure. It also contributes to the release of hormones (荷尔蒙) that are good for our health. 17 . It helps us feel more at ease around new people and also connects us with others.Sometimes, you might feel like there is not much cause to laugh. Life can be tough. But laughter is, if not the best medicine, a good support to have for tough times and for good times as well. So you should allow yourself to laugh as you used to.A good idea is to give yourself permission to play. Play is a natural activity that promotes a lot of laughter, whether it's through video games, outdoor games, or board games. 18 .Laughter comes from being with others. 19 . Hang out with family members that are nice to be around, with whom you can have fun, laugh, and enjoy yourself. Give your time to those who can share your laughter.More than anything, learn to develop humor. 20 . Laugh at your mistakes and learn to laugh at yourself. Then you will be surprised by the changes you will see in your life.A.You don’t have to be meanB.Laughter has a lot of benefitsC.Don’t take yourself too seriouslyD.Try to see your friends more oftenE.Watch videos to help you correct your mistakesF.In addition to these, laughing has a social functionG.Just discover what you like to play and have fun with it二、完形填空Granny Basketball is more competitive than you’d think!

Wang Dewen, known as “Grandpa Amu” on YouTube, has been praised as the modern-day Lu Ban, a well-known Chinese structural engineer during the Zhou Dynasty, thanks to his rich carpentry knowledge.Grandpa Amu’s most popular video, which shows him making a delicate wooden arch bridge, has gone viral on YouTube, gaining more than 40 million views. “If you do something, you have to love it, and you have to be interested in it; however, being interested doesn’t mean there’s only happiness and no pain.” Grandpa Amu shared when talking about his excellent carpentry skills.His most popular works include a folding stool, a model of the China pavilion from the 2010 Shanghai Expo, and an apple-shaped interlocking puzzle, known as a Lu Ban lock. Grandpa Amu follows an ancient Chinese mortise and tenon (榫卯) technique, which means no nails or glue are involved in the entire process of building the arch bridge.The master carpenter has also made several wooden toys for his grandson using the same technique. His young grandson’s favorites include a walking Peppa Pig and a bubble blowing machine. With over 1.17 million fans on YouTube, Grandpa Amu’s videos so far have gained more than 200 million views.His wonderful woodworking skills were developed from the age of thirteen as a way of supporting his family in East China’s Shandong Province. “The grandson is so happy, as there have been so many fine and unique toys made by grandpa from an early age,” commented onenetizen, while another said, “It’s amazing. I hope these traditional crafts can be passed on!”4.What do we know about Grandpa Amu from the first paragraph?A.He is made fun of on the Internet.B.He aims at spreading Chinese culture.C.He has made a lot of fortune on the Internet.D.He is well known for his carpentry skills on the Internet.5.What can we infer from Grandpa Amu’s words in Paragraph 2?A.Outstanding skills lie in hard work.B.Success depends on passion.C.Interest brings not merely happiness.D.Theory is from practice.6.What is the unique feature of Grandpa Amu’s craft works?A.The apple shape.B.No nails or glue.C.The folding stool.D.The wooden material.7.What probably made Grandpa Amu work as a carpenter?A.His interest in woodworking.B.His grandson’s requirement.C.His support for his family.D.His wishes to pass on the traditional crafts.In most Hollywood movies, the Native American Navajo s still fight on horses in the American Southwest. But during World War II, a group of Navajos made their language into a weapon to protect the United States. They were the Navajo Code Talkers, and it is one of the few unbroken codes in military history.Navajo was the perfect choice for a secret language. It is very complex. One vowel (元音) can have up to ten different pronunciations, changing the meaning of any word. In the 1940s, Navajo was unwritten language. No one outside of the reservation (居留地) could speak it or understand it.The Navajo Code team had to invent new words to describe military equipment. For example, they named ships after fish: lotso-whale(battleship), calo-shark (destroyer), beshloiron-fish (submarine). When a Code Talker received a message via radio, he heard a series of unrelated Navajo words. He would then translate the words into English and use the first letter of each English word to spell the message. The Navajo words tsah (needle), wol-la-chee (ant), ah-kh-di-glini (victor), and tsah-ah-dzoh (yucca) spelled NA VY.The Code Talker kept the code a secret. They memorized everything. There were no code books. As a result, no ordinary Navajo soldiers, if captured by the enemy, could understand the code. More than 3,600 Navajos served in World War II, but only 420 were Code Talkers with the US Marines. They coded and decoded battlefield messages better and faster than any machine. They could encode, transmit, and decode a three-line English message in 20 seconds. Machines of the time required 30 minutes to perform the same job.Even after the war the code remained top secret. When they were asked about their role, Code Talkers just said: “I was a radioman.” War movies and histories came out without mentioning them. The code was never used again and only in 1968 did the secret come out. 8.Why could Navajo be used as a military code?A.It had a complex writing system.B.It was designed specifically for World War Ⅱ.C.Only the Navajos could understand it.D.Navajo words varied greatly in pronunciation. 9.What would the Navajo Code team do right after receiving a message?A.Put it into English in a secret way.B.Record it in Navajo letters.C.Put the Navajo words in order.D.Submit it to the officer immediately. 10.What is paragraph 4 mainly about?A.Heroic deeds of Navajo Code Talkers.B.Working contents of Navajo Code Talkers.C.The difficulty of becoming a Navajo Code Talker.D.The professionalism of Navajo Code Talkers.11.What can be inferred from the passage?A.The Navajo Code Talkers can be found to fight on horses in US movies.B.Around 12% Navajo soldiers were taken prisoners during World War Ⅱ.C.War messages were translated into English through Navajo code books.D.The Navajo language contributed a lot to the US army in World War Ⅱ.Developed by Urban Villages and designed by Studio Gang, Populus will open in the summer of 2024 as America’s first carbon-positive hotel. Studio Gang took inspiration from the patterns of Colorado’s native Aspen trees, with the building’s windows looking like the trees’ distinctive “Aspen Eyes”.Situated in downtown Denver, the hotel will achieve its carbon-positive status thanks to itssustainable design and a unique off-site project. The hotel has committed to planting enough trees to represent over 5,000 acres of forest. This will offset an embodied (隐含的) carbon footprint equal to nearly 500,000 gallons of gas and remove additional carbon dioxide from the atmosphere.Populus has been created to meet the increasing preference by today’s consumers to travel responsibly, experience places in an authentic way, and connect more deeply with nature. Using low-carbon concrete, high-recycle content materials, and minimizing waste are all helping the hotel reach its carbon-positive goal. There is also no planned on-site parking, which will encourage visitors to take public transportation or use existing structures, thus saving the hotel from having to build a parking lot, which requires the use of materials rich in carbon.When thinking about the look of the hotel, Studio Gang turned to nature for its design inspiration. And the building’s unique windows, not only recall the pattern of the Aspen tree but also help its energy efficiency. The “covers” over each window provide interior shade, which improves energy use and also channel away rainwater to keep the building looking clean.As a benefit to guests, each room will have incredible views and the windows transform into seats or desks that invite them to enjoy the great outdoors—even when they’re inside.The hotel will also include a rooftop restaurant that overlooks the mountain s and city skyline, with the intention to immerse guests in nature. The rooftop will be open to the public and will be filled with regional vegetation, serving as a lush (草木茂盛的) place for the community to socialize.12.What does the underlined word “offset” in paragraph 2 mean?A.Produce.B.Cancel.C.Include.D.Require. 13.What do we know about Populus?A.It has planted over 5,000 acres of trees.B.It is designed to meet the demands for environmental travel.C.It can’t be accessed through driving for no planned on-site parking.D.It will include a rooftop restaurant open to the public for free.14.What’s the author’s attitude toward the hotel?A.Doubtful.B.Indifferent.C.Positive.D.Disapproving. 15.What can be a suitable title for the text?A.Populus: First Carbon-Positive Hotel in America B.Populus: A Hotel in DowntownDenverC.Populus: Contributor to the Change of America D.Populus: A Hotel with “Aspen Eyes”It is a great challenge of descriptive writing: finding that balance between using enough details to bring your description to life, but not so much that your readers are fed up with it. 16 Remember, you’re writing a description, not taking a photograph. 17 If you were photographing a tree, you would still make choices — lighting, framing, focus — that would capture the essence of the tree, but not its exact image.Trust your readers. Stephen King says in On Writing, “Description begins in the writer’s imagination, but should finish in the readers.” 18 If you offer an exactly right description — rather than a complete description — the readers’ completion of your description will be close enough to what you want them to “see” in the picture.19 If you write this: “Wind stirred (吹动) the maple’s boughs, spurring leaves to wavelike a million green hands greeting them to hurry to its shady embrace”, you have created a real description, and you don’t need to write that the tree is big.Let actions take the place of description. This can be effective in describing emotions. Instead of “Sue felt sad as she stared at their wedding photo.”, try “Sue stared at their wedding photo until her stinging eyes could no longer focus. She turned the photo face down on her nightstand.” We now know, through her actions, that Sue is sad. 20 That is because we’re experiencing her physical reactions (stinging eyes) and actions (turned the photo face down) along with her.A.Focus on readers’ emotions.B.Readers can fill in the picture.C.Describe facts instead of actions.D.Embrace the use of metaphors and similes.E.It is not necessary to document every detail.F.Besides, we now feel more connected with her in that sadness.G.Fortunately, there are techniques you can use to find that balance.二、完形填空I have always been a big girl. I am comfortable with my body but there is a price to pay for being 21 .In primary school, I was enthusiastic about gymnastics but I had to 22 my shortcomings by hours after hours of extra practice, going over every routine.
