重庆实验外国语学校2023-2024学年高一上学期期末考试英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解Many countries around the globe pride themselves on their lingual diversity. Here are a few of the most polyglot places on Earth.ArubaAruba sits in the far southern Caribbean sea near V enezuela. Dutch is an official language and is taught in all schools, both English and Spanish are also compulsory(必修的)languages in Aruba’s education system. However, none of these languages is considered the native language of Aruba on the street, at home locals communicate with one another in Papiament. Papiamento is an official language alongside Dutch, and it is used regularly in the media and in government.East TimorThis tiny young nation sits in the far south-eastern comer of the Indonesian Archipelago. Once a colony(殖民地)of Portugal, Timor decided to adopt Portuguese as an official language after independence. The local tongue, Tetum, is the most widely spoken language on the street. In addition, English and Indonesian are used throughout the country, and both are officially recognized as working languages.IndiaHindi and English are the official national languages of India, and the majority of educated Indians have knowledge of both, though English is preferred over Hindi in southern India. Each state in India has its own official language (s), most of which differ from Hindi. These languages are used in the local media and on the street.South AfricaSouth Africa has 11 official languages. In many urban areas, English is the lingua franca (通用语). It is also the main language of the government and media, even though less than ten percent of South Africans speak it as a first language. Afrikaans, a Germanic language similar to Dutch, is spoken in the southern and western regions of the country. South Africa has nine official Bantu languages, of which：Zulu and Xhosa are the most common. 1．Which of the following is the official language of Aruba?A．Dutch and Spanish.B．Dutch and Papiamento.C．Spanish and English.D．English and Papiamento.2．Which of the following is true according to the passage?A．Aruba was once a colony of Portugal.B．East Timor lies in the far southernCaribbean sea.C．English is preferred over Hindi in India.D．South Africa media uses English as the main language.3．What do these places have in common?A．They adopt English as an official language.B．They are education-centred places.C．They have more than two official languages.D．They are multilingual communities.The first time I realized that I had a love for sports competitions was during the Field Day in elementary school. Small for my age, and more of a bookworm than a sports lover, IDay, which focused on individual skills, was different. In the Softball Throw event, I got my first taste of sporting victory. Credit goes to the example of my first coach, my father. He lifted weights every morning at home. He bought us all baseball gloves and hats, and in the warm months, we spent hours playing catch.Once I got to sixth grade and switched to private school, our entire student body was assigned to either the Red or the White team. Throughout the year, we competed against each other in various games and exercises for points. I eventually became president of The Committee of Games. I also played on the field hockey team and the basketball team. And at home, playing tennis, skating, skiing and biking were simply normal things we did. During the break time, magazines were also quite popular for us teens. These regularly featured articles on physical exercise. Somehow, my college roommate and I took up the habit of completing Royal Canadian Air Force (RCAF) exercises every day, a practice that continued into my marriage, when we had no spare money to use to join a gym.So, though it shocks some of our friends, that early foundation continued in adulthood into a sports and fitness focus, considered important even on vacation. I still love reading and the arts, too. As far as I’m concerned, life is the richest with my feet in both worlds. 4．What does the underlined word “humiliation” mean in Paragraph 1?A．Stress.B．Threat.C．Shame.D．Glory.5．According to the author, what contributes to her victory in the Softball Throw event?A．Her confidence in her sports skills.B．The efforts she put into exercising.C．Her advanced sports gloves and hats.D．The strong influence of her father. 6．What happened after the author stepped into adulthood?A．She changed the focus into reading.B．She stuck to working out.C．She regularly exercised on weekends.D．She joined Royal Canadian Air Force. 7．What is the author’s purpose in writing the text?A．To express her love for sports.B．To show her father’s guidance on sports.C．To stress the advantages of physical exercise.D．To share her childhood memories about sports.You might think of martial arts movies when you see people performing graceful moves down a river, all standing on a bamboo strip, but actually it is a form of intangible cultural heritage: single bamboo drifting (独竹漂).Over 2,000 years ago, the high-quality wood, nanmu, in Guizhou was in great demand by the royal court in the north. With no better transportation, people had to stand on one log to drift down the river. Later, local people began to compete along the way and the game of wood drifting was born. In the Qing Dynasty, wood drifting became single bamboo drifting because of bamboo’s lower price. Due to various skills it takes for one to master this act, single bamboo drifting was included in the national intangible cultural heritage list in 2021.Yang Liu, an inheritor (继承者) of single bamboo drifting, learned it at 7. “Usually, the bamboo under our feet is about 9 meters long, and the bamboo in our hands is about 5 meters. If the length of the bamboo is not long enough, it will not float. Keeping our feet firmly positioned on the narrow bamboo pole is the key, so we should fight against the current (水流) by constantly changing the angle. I lost my balance and fell into the water many times while practicing. Once I fell, I gave it another try until I knew how to handle the most difficult part,” she said.The love for the ancient skill keeps Yang going. Yang also shows creativity when spreading the culture of single bamboo drifting. For example, she includes dance in single bamboo drifting to make it more graceful. As han fu culture has been on the rise, Yang started wearing hanfu while performing, creating a more beautiful feel. In 2020, Yang began to post her videos on social media. “I’m extremely proud to get the response from viewers that singlebamboo drifting makes the line between what is possible and impossible unclear. It’s my mission to keep it alive and make it known to more people,” Yang Liu told China Daily. 8．What can be learned from the first two paragraphs?A．Nanmu was delivered to the north by land.B．Single bamboo drifting needs lots of skills.C．Bamboo was costly in Guizhou over 2,000 years ago.D．The martial arts movie is a form of cultural heritage.9．What is the biggest challenge in learning single bamboo drifting?A．Keeping balance on a bamboo pole.B．Maintaining a fixed angle.C．Finding the proper bamboo.D．Holding the bamboo firmly in hands. 10．What do the viewers think of single bamboo drifting?A．It’s confusing.B．It’s impossible.C．It’s unbelievable.D．It’s effortless. 11．Which of the following is a suitable title for the text?A．Balancing with Grace B．Chinese Cultural HeritageC．A Creative Performer D．Transporting Bamboo down the RiverResearchers in China have found a new, genetically (基因上) pure species of the critically endangered Chinese giant salamander (中国大鲵) in the wild. The new species was found in a largely undisturbed part of the Jiulingshan National Nature Reserve in Jiangxi Province. The animals are the only known genetically pure, reproducing giant salamander population in its natural habitat in the country. “The discovery of the new species in a closed nature reserve provides hope that other genetically pure species may still exist in other such places,” said Robert Murphy, a professor at the University of Toronto and one of the co-authors of the study.The Chinese giant salamander is believed to have remained almost unchanged for 170 million years. While Chinese giant salamanders used to be thought of as one species, recent studies have revealed that there are five to eight genetically distinct species in the country. However, the species arc under great threat of extinction due to habitat loss, water pollution and overexploitation (过度开发) of wild populations over the past decades.Chinese giant salamanders have been protected in China since the 1980s. “After the discovery of multiple species of Chinese giant salamanders, China quickly put into place several actions, such as providing additional funding for critical research, establishing a seriesof nature reserves for the species, and promoting cooperation between scientists and biologists,” Murphy said.The researchers are now trying to track down more giant salamanders. Murpby said the discovery opened up new possibilities, such as establishing breeding farms with genetically pure salamanders to help populate ecosystems. In their paper, the researchers also stressed the importance of undisturbed habitats for protecting wildlife. “Closed nature reserves a new pathway for discovering and conserving endangered species,” they said.12．Why is the new discovery by Chinese researchers important?A．It confirms the need for more independent studies on biodiversity.B．It proves the genetic transformation of Chinese giant salamanders.C．It suggests the importance of increasing funding for nature reserves.D．It indicates the presence of other genetically pure species elsewhere.13．What can be learned from paragraph 2?A．Some species of Chinese giant salamanders have become extinct.B．Chinese giant salamander numbers have declined in recent decades.C．Chinese giant salamanders have remained unchanged for 170 million years.D．Some breeding programs have been launched to protect Chinese giant salamanders. 14．What is paragraph 3 mainly about?A．China’s lessons from the past.B．China’s cooperation with other countries.C．China’s efforts to protect giant salamanders.D．China’s ambition to develop new nature reserves.15．What would the researchers most probably agree with according to the last paragraph?A．More closed nature reserves should be established.B．Traditional conservation methods are more efficient.C．Mixed breeding can be used to protect endangered species.D．Large breeding farms are beneficial to the growth of giant salamanders.How to Feel ConnectedIt’s easy to feel disconnected from what is going on around you in today’s fast-paced world. 16 You can get in touch and feel connected, however, by following the tips below:Consider why you feel disconnected. Knowing what is making you feel disconnected can help you choose the best ways to address it. 17 Ask yourself these questions: Are you keeping yourself occupied with work too much? Do you rely on electronic communication instead of face to face communication? Do you lack friendships that are satisfying?Interact with people in person. Technology is a great way to stay in touch, but sometimes you need to spend time with other people in person. 18 Or simply visiting someone once a week can keep it strong. You can also take steps to feel more connected by making small-talk with strangers who are sharing parts of your day.19 Your loved ones could feel shy, so you may never know how to improve your relationship unless you ask the right questions. Asking them to open the doors can give you some insight on what you can do. Learning this information can help to strengthen your bond.Show your commitment to them. Simply showing up and being there for your loved ones says a lot about how much you value your relationships. Putting in the time shows them that you are committed and want to stay connected. 20A．Ask others what they need from you.B．Sometimes you can feel isolated and distant from the ones you love.C．Be brave to express your love.D．Reach out to people to schedule a time to get together.E．Attending family events can help to strengthen your relationship.F．Targeting your efforts toward those issues allows you to close that distance more effectively.G．You can have a gift delivered to friends on special occasions.二、完形填空Five years ago, my husband and I bought a farm.
