2024-2025学年度第一学期高一英语期中考试卷试卷满分:100分第一部分阅读理解(共20 小题;每小题2.5 分,满分50 分)第一节阅读下列短文,从每题所给的A、B、C 和D 四个选项中,选出最佳选项。

AHere are some pet-friendly universities in the UK and US.University of IllinoisStudents are allowed up to two pets in each apartment, as well as a fish tank of no more than 50 gallons.To keep a pet, you will need to get approval from the Family & Graduate housing department at the University of Illinois. You will have to provide proof that your pet is up to date with its vaccinations(疫苗), and pay a monthly US$30 pet fee, which is non-refundable(不可退款的).Your pet can’t be left for extended periods of time, and if there’s evidence that you’ve left it alone due to vacation or illness, the university may remove it.Harvard UniversityWith as many as 12 pet-friendly apartments, Harvard is a very pet-friendly university. It allows students to have fish in a tank of no more than 50 gallons, except for Harvard’s Cronkhite Graduate Center.In Harvard’s pet-friendly apartments, you’re allowed: one cat or one dog, which can’t be over 40 pounds when fully grown. At most, two pet birds.University of British Columbia Students can take advantage of the university’s B.A.R. K program, which uses the calming power of therapy dogs to help them.B.A.R. K started at the University of British Columbia, after an assistant professor called Dr. John-Tyler Binfet noticed that he couldn’t walk across campus without students running over to play with his dog, Frances. The students told him they were homesick and missed their pets, which encouraged Binfet to establish B.A.R. K as a way of fighting their loneliness.University of OxfordThe University of Oxford is famous for its resident pets, who happily wander around college grounds. Many Oxford colleges have their own tortoise and take part in the annual Corpus Christi tortoise race.Although you are not allowed to keep your own pet as a student, several Oxford colleges hold dog petting and walking therapy sessions.1.What is one of the rules for keeping pets at the University of Illinois?A.Pet keepers should pay a monthly US$ 30 pet fee which will be returned.B.Pets can’t be left alone in the apartments due to vacation or illness.C.Students have to keep fish in a fish tank of no more than 20 gallons.D.The cat or dog can’t be over 40 pounds when fully grown.2.Why did Dr. John-Tyler Binfet start B.A.R. K?A.To help students to fight against homesickness.B.To do research on dogs and train them to be pets.C.To help more professors to do exercise on campus.D.To give assistance to the pet dogs by offering them foods.3.Which university doesn’t allow students to keep pets?A.Harvard University. B.University of Oxford.C.University of Illinois. D.University of British Columbia.BA survey by the American Psychological Association shows that one in ten adults reads online news at least once an hour. A lot has been written about the mental health influence from news addiction, and in particular from reading negative reports. Just like junk food, “junk” news can be bad for our health.In recent years, things have been getting increasingly more negative. A study of the content of New Zealand’s largest newspaper showed that while in 1973 the average number of stories about death on the front page was 0.75, by 2013 it was 4.1(and no, there weren’t five times more people dying).What’s more, online news, and the stories we read on mobile phones in particular, tend to be even more negative than print. A 2019 study of 50 U.S. newspapers showed that mobile versions of newspapers report three times more stories about disasters and accidents than paper ones.Such negative reports lead people to believe that things are worse than they really are. They can lead to stress, worry and lower spirits.Experiments also suggest that loneliness and poor relationships have been connected with reading negative reports. After reading negative reports, people are less likely to help others. Even worse, when we check news on smart phones, we may “phub” our loved ones, which leads to lower relationship satisfaction.Negative reports attract our attention far more than positive ones. That’s a global happening. I hope, however, that if we realize that negative news is spoiling our moods, we might all be more willing to change. 4.Why is “junk food” mentioned in the first paragraph?A.To entertain readers.B.To introduce the topic.C.To make an advertisement.D.To keep readers away from it.5.What can we learn about the study in Paragraph 2?A.The death rate in New Zealand is very high.B.Print newspapers have become less popular.C.Stories about death have become less popular.D.Negative reporting has been increasing over years. 6.What may negative reports lead people to do?A.Live a hopeful life.B.Become more careful.C.Become less likely to help others.D.Pay more attention to their physical health.7.What does the underlined word “phub” in Paragraph 5 mean?A.Ignore B.Hate C.Laugh at D.Care about8.Which of the following can be the best title for the text?A.A Survey on News Reading Habits B.Negative Effects of Mobile PhonesC.Is Online News Better Than Print?D.Is Junk News a Danger to Health?CThere was once a boy called Mario who loved to have lots of friends at school. However, he wasn’t sure whether or not his classmates were his true friends, so he asked his grandpa. The old man answered, “I have just exactly what you need; it’s in the attic (阁楼). Wait here for a minute.”Grandpa left, soon returning as though carrying something in his hand, but Mario could see nothing there. “Take it. It’s a very special chair. Because it’s invisible (无形的) it’s rather difficult to sit on, but if you take it to school and you manage to sit on it, you’ll be able to tell who your true friends are.”Mario took the strange invisible chair and went to school. At break time he asked everyone to form a circle, and he put himself in the middle, with his chair. “Nobody move. You’re about to see something amazing,” Mario said.Then Mario tried sitting on the chair. He missed and fell straight onto his backside. Everyone had a pretty good laugh. Mario wouldn’t be beaten. He kept trying to sit on the magic chair, and kept falling to theground... until, suddenly, he tried again and didn’t fall. This time he sat, hovering (悬停) in mid-air.Looking around, Mario saw George, Lucas, and Diana — three of his best friends — holding him up, so he wouldn’t fall. At the same time, many others he had thought of as friends were doing nothing but make fun of him, enjoying each and every fall.Leaving with his three friends, Mario explained to them how his grandpa had so cleverly thought of such a good idea. Now he knows that those who take joy in our misfortunes (不幸) when we are in difficulty are not our true friends.9.What did Mario’s grandpa take from the attic?A.An invisible chair.B.An old chair.C.A real chair.D.Nothing.10.Why did Mario’s grandpa give him the invisible chair?A.To see whether Mario could sit on it. B.To test who were Mario’s true friends.C.To let Mario have fun with his classmates.D.To test whether Mario was popular at school. 11.How was Mario able to hover in mid-air?A.He saw the invisible chair suddenly. B.He managed to sit on the chair finally.C.His friends held him up with their hands. D.His classmates gave him a chair to sit on.12.What does the story tell us?A.Never laugh at our friends. B.True friends can help us do magic.C.True friends are those who care for us. D.Having too many good friends isn’t a good thing.DSure, it’s good to get along well with your teacher because it makes the time you spend in the classroom more pleasant.And yes, it’s good to get along well with your teacher because, in general, it’s smart to learn how to get along well with the different types of people you’ll meet throughout your life.In fact, kids who get along well with their teachers not only learn more, but they’re more comfortable with asking questions and getting extra help. This makes it easier for them to understand new materials and makes them do their best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school issues (问题).Here is a question:What if you don’t get along with your teachers? In fact, teachers want to get along well with you and enjoy seeing you learn. But teachers and students sometimes have personality clashes (个性冲突), which can happen between any two people. If you show your teacher that you want to make the situation better, he or she will probably do everything possible to make that happen. By dealing with a problem like this, you learn something about how to get along with people who are different from you.However if a certain teacher isn’t your favorite, you can still have a successful relationship with him or her especially if you fulfill (履行) your basic responsibilities as a student.Here are some of those responsibilities (责任):Attend class ready to learn.Be prepared for class with the right stationery, books, and completed assignments (作业).Listen when your teacher is talking.Do your best, whether it’s a classroom assignment, homework, or a test.13.According to the passage, what will happen to you when getting along well with your teachers ?A.We will have no problems with studyB.We will get a better seat in the classroomC.We will get the best scores in the examsD.We will have more pleasant time in the classroom14.What does the underlined word “that” refers to in the fourth paragraph?A.The happy time you have in the classroomB.Getting along very well with classmatesC.A better relationship between you and your teacherD.The disappearance of personality differences15.What does the passage mainly talk about?A.The importance of friendship in schools.B.The importance of a good relationship with your teachers.C.Studying skills for students.D.Useful skills to get along well with your teachers.16.As a student, what will you do if you don’t like a certain teacher ?A.You fulfill (履行) your basic responsibilities as a studentB.You are thought of as a good studentC.You know some basic social skillsD.You are easygoing and helpful第二节七选五(每小题1分,共5分,根据短文内容,选出能填入空白处的最佳选项。

He must have drowned.Now with only one bookshop in town,business was better for George.But sometimes he sat in his narrow,old kitchen and gazed out of the dirty window,thinking about his formal rival(竞争对手). Perhaps he missed him?George was very interested in old dictionaries.He’d recently found a collector in Australia who was selling a rare first edition.When the parcel arrived,the book was in perfect condition and George was delighted.But while he was having lunch,George glanced at the photo in the newspaper that the book had been wrapped in.He was astonished—the smiling face was older than he remembered but unmistakable! Trembling,George started reading.“Bookends have bought ten bookstores from their rivals Dylans.The company,owned by multi-millionaire Richard Pike,is now the largest bookseller in Australia.”60.George

ConditionsLaj amanu,Australia,is a dry little town,sitting right on the edge of the Tanami desert.Can you imagine how surprised people were when live fish rained down on them from a darkgray cloud.It happens that there are similar cases in England and Honduras.How do clouds make fishy?The simple answer is that they don’t.There is a particular weather phenomenon(现象)called a waterspout.A waterspout is just like a tornado(龙卷风),only it forms above oceans,lakes,or rivers.Like a tornado,a waterspout moves in a circle at high speeds.When it moves above the water,it tends to carry the fish with it,as well as frogs orother small plants or animals.Scientists couldn’t work it out at first.To make matters stranger still,the fish in Honduras were very much alive when they rained down to the ground,but they were all blind.In England and Australia,it rained fish and snakes,and none were blind.It was difficult to puzzle out,but the blind fish gave them a place to start.Scientists knew that some fish that lived in deep,underground caves with no light sources often lost their eyesight.So when blind fish rained down on Honduras,scientists began toconnect some clues(线索,提示).Clearly,these particular fish were pulled from an underground water sourceby force.It has rained fish on every continent,and each time,people have tried in various ways to explain this strange phenomenon.Historically,villagers thought the“fishes from the heavens”might be answers to prayers(祈祷)for food.Others suggested that floods overran river banks and oceans,leaving the fish on the city streets.No scientist had actually seen the rain as it occurred, only the fish left on the ground.But in1990,a National Geographic team happened to be in Honduras when the Rain of Fishes began.They recorded what was happening and made historyby finally proving that the fish really did fall from the sky.This huge breakthrough wasn’t just a spot of good luck.It changed thousands of yearsof myths(虚构的事;谬论)and legends into true stories and provided scientific explanations for how fish came to live in deep caves.It explained ancient cave paintings and cast(投射光线)new light on how species have spread over time.It turned out to be a lot more than just a little fishy weather.68.According to the passage,a waterspout________.A.can make animals blindB.is difficult to catch on filmC.can carry items(物品)with itD.is a dangerous sea creature69.The blind fish made the scientists start to think that________.A.raining fish was a warning of natural disastersB.animals changed to match their environmentsC.the weather system differed from place to placeD.the waterspout theory seemed more possible70.The first sentence in the last paragraph probably suggests that________.A.waterspouts came to be a center of scientific researchB.the scientists were fortunate to have made their discoveriesC.hard work went into determining the cause for the raining fishD.the scientists relied heavily on unusual events to drive their studies71.The author writes the passage to________.A.explain what caused the fishy weatherB.describe the magic phenomenonC.persuade people to protect the environmentD.encourage people to do scientific research(D)A study involving8,500teenagers from all social backgrounds found that most of them are ignorant(无知的)when it comes to money.The findings,the first in a series of reports from NatWesl that has started a five-year research project into teenagers and money,arc particularly worrying as this generation of young people is likely to be burdened with greater debts man any before.University tuition fees(学费)are currently capped at£3,000annually,but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.In the research,the teenagers were presented with terms(条款)of four different loans but 76per cent failed to identify the cheapest.The young people also predicted that they would be earning on average£31.000by the age of25,although the average salary for those aged22to29is just£17,815.The teenagers expected to be in debt when they finished university or training,although half said that they assumed the debts would be less than£10.000.Average debts for graduates are £12,363.Stephen Moir,head of community investment at the Royal Bank of Scotland Group which owns NatWest,said."The more exposed young people are to financial issues,and the younger they become aware of them,the more likely they arc to become responsible,forward-planning adults who manage their finances confidently and effectively."Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs.They have just introduced new lessons in how to manage debts.Nikki Fairweathcr.aged15.from St Helens,said that she had benefited from lessons on personal finance,but admitted that she still had a lot to learn about money.72.Which of the following can be found from the five-year research project?A.Students understand personal finances differently.B.University tuition fees in England have been rising.C.Teenagers tend to overestimate their future earnings.D.The students'payback ability has become a major issue.73.The phrase"to raise the ceiling"in paragraph2probably means"______".A.to raise the student loansB.to improve the school facilitiesC.to increase the upper limit of the tuition(学费)D.to lift the school building roofs74.According to Stephen Moir,students_______.A.are too young to be exposed10financial issuesB.should learn to manage their finances wellC-should maintain a positive attitude when facing loansD.benefit a lot from lessons on personal finance75.What can we learn from the passage?A.Many British teenagers do not know money matters wellB.Teenagers in Britain are heavily burdened with debts.C.Financial planning is a required course at college.D.Young people should become responsible adults.Section C(8分)Directions:Read the following passage.Fill in each blank with a proper sentence given in the box.Each sentence can be used only once.Note that there are two more sentences than you need.A.Its goal is to have good,clean,fair food for all people.B.Today,there are great concerns about the way people grow and produce food.C.It should arrive on our plates in the cleanest and most environmentally responsible way.D.All people should be able to purchase healthy food.E.This event wasn’t the only thing that started the Slow Food Movement.F.Today the Slow Food Movement has already expanded out of Italy.The Slow Food Movement started in Rome,Italy in1986.When a new McDonalds was opening near a beautiful historic place,some people stood outside the restaurant and shouted,“We do not want fast food.We want slow food!”(76)________One day Carlo Petrini went to a restaurant to eat a traditional meal.But thefood didn’t taste the same as he remembered.He learned that the peppers were shipped from abroad because the prices were low.This deeply concerned Carlo.Carlo wanted people to care about where their foods came from and how their foods madetheir culture special.So he started a group to encourage this idea.It soon became the Slow Food Movement.(77)________First,what is good food?Good food is fresh.The vegetables are eaten close to the placewhere they are grown.The fish hasn’t been sitting for days before it is eaten.Good food is seasonable.It should be grown at the best time of the year for that food.Good food satisfies the senses.It should look good,smell good and taste good.And finally,good food is cultural food. Each country has special foods that make it different.Second,food should be clean.(78)________Farmers use chemicals to kill insects andfeed plants.But the chemicals can also harm the natural environment around farms.Over time, they can cause health problems in people too.Clean food means food that does not harm our bodies or the environment.And third,food should be fair.Food should not cost too much money.(79)________Thepeople who grow and make food should be paid fairly for their work.They should work in safe, Healthy conditions.第二卷I.Translation.(3+4+4+5=16分)80.作为学生,我们不应该无视校纪校规。

in1945,he taught in middle schools and later in the Physics Department of Peking University.In1948,he was admitted to the Graduate School of Purdue University in the United States and received a PhD in physics two years later.Nine days after he got his doctoral degree.he stepped onto the ship back to China and started his creative nuclear theoretical research.Deng Jiaxian set up classes,giving lessons himself and organizing people to translate and study relevant foreign language materials.At the same time,he never gave up on his ideas re-guiding the main direction of atomic bomb
