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 &amp; 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。
