四川省成都外国语学校2021-2022学年高二下学期期中考试英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解Beijing is the first city ever to hold both Summer and Winter Olympic Games. Now, let’s take a look at some of the most popular events in the Winter Olympic Games.Figure skatingFigure skating is one of the most popular sports at the Winter Olympics, where ice skaters, singly or in pairs, perform freestyle movements of jumps, spins, lifts, and footwork in a graceful manner. The figure skating competition is one of the fiercest at the Winter Olympics. To win the game, the skater can’t make any mistakes.CurlingCurling is one of the most unique sports at the Winter Olympics — a winter sport played by two teams of four players on a rectangular sheet of ice. The two teams take turns to slide large round flat stones towards a target. Members of each team use brooms to sweep the surface of the ice in the path of the stone to control its speed and direction.And while curling may be a “slow” sport, it’s still full of skill, suspense and excitement!SnowboardingSnowboarding is a popular winter sport that involves sliding downhill on snow with a snowboard firmly attached to a rider’s feet. The sport is said to have been inspired by surfing, skiing and skateboarding, as an alternative to alpine skiing (高山滑雪).While snowboarding is one of the newer events — first included at the 1998 Winter Olympics, it has become one of the most popular and exciting sports at the Winter Olympics.Ice hockeyIce hockey is a game between two teams who wear skates and compete on an ice rink (溜冰场). Each team usually has six players. The object is to push the puck (冰球) past a goal line and into a net guarded by a goalkeeper. Ice hockey is popular for its speed and frequent physical contact. Worldwide there are more than a million registered ice hockey players performing regularly in leagues.1．Figure skates ought to be ________.A．elegant and faultlessB．inspiring and excitingC．skillful and defensiveD．calm and fashionable2．Which of the winter sports mentioned above involves team work?A．Figure skating and Curling.B．Curling and Ice hockey.C．Snowboarding and Figure skating.D．Snowboarding and Ice hockey.3．What do we know about these winter sports from the passage?A．Snowboarding originated from skiing, surfing and shooting.B．Figure skating enjoys the greatest popularity.C．Over a million become ice hockey league members each year.D．The curling ice path is brushed to help the stone slide.I fell in love with music from a young age and often sat down making a few songs of my own.What would life be like, I wondered, without a beautiful song? In 1992, I made two love songs to my darling wife and watched tears run down her face as I sang.“Sam,” she said earnestly, “Your songs should be heard by more people.”She got my ballads and started bothering various media people about me, her singing barber husband. Two radio stations took an interest and played the songs. After the programme was aired, I became known in our community as the Singing Barber.The biggest surprise, however, was still to come. I received a call from a music promoter who offered me a long-term recording contract. He explained that he would be investing a lot of money to market my songs. I needed to be wholly focused on selling my records all over Australia.But I hesitated.My friends all told me to go for it. And Mary also thought I should do. “Go, Sam. I’ll manage with the family...it’ll be OK.”I watched my daughter and son playing in the backyard. Soon they would both be in high school and where would I be? I was so used to my family turning to me for love and support. If I were to start a singing career, I would not only miss them terribly, I’d also certainly miss out on watching them grow up. Signing this contract would put a huge gapbetween my family and me and I couldn’t bear it. My family was my life. So I refused the music promoter’s offer. I’m still making music. I’m rich in love and I have no regrets. 4．When the author was offered the contract, most of his friends _______.A．envied himB．laughed at himC．encouraged himD．didn’t believe him5．Why did the author give up the contract?A．Because his wife was strongly against it.B．Because the pay was not attractive enough.C．Because he wanted to care about his two kids.D．Because he didn’t want his family life damaged.6．According to the passage, we can infer that the author _______.A．used to be a country singerB．preferred his present lifeC．went on the road to fameD．regretted giving up his contract7．What does the author mainly intend to tell us?A．One should know himself.B．Interest is the best teacher.C．Family should come first.D．Every dog has its day.Nearly two years after the COVID-19 outbreak, China has granted approval to its first antibody combination therapy for COVID-19 treatment, adding a tool to the world’s fight against the disease.A team from Tsinghua University, along with the Shenzhen People’s Hospital, has accomplished the task in 20 months. It would usually take 10 years. “It can reduce the rate of hospitalization and death by 80 percent,” said Zhang Linqi, leader of the research team.The new antibody drug is immediately effective after being used. Moreover, the therapy can protect people, especially those whose physical condition doesn’t allow vaccination (接种疫苗), from becoming infected (感染) by COVID-19 for around 9 to 12 months, saidZhang.How does it work? When a virus infects a cell, it relies on an important type of protein: the spike proteins (棘突蛋白) on its surface. The spike proteins serve as a key to unlocking a cell. If a virus cannot enter a cell, it will disappear immediately. The job of our antibodies is to block the virus from entering cells. So its target is very precise. In addition, thanks to the coordination between the two antibodies, it is highly efficient in preventing the virus, according to Zhang. The qualities of the new drug make it especially useful for high-risk groups, such as frontline medical workers and people not suitable for vaccination due to various underlying health problems.The new drug is expected to come to the market soon, but it’s not cheap. That’s because of limited production. Noting that China has used science and technology to fight COVID-19 since the beginning of the outbreak, Zhang said, “Science is the key to solving the issue. Science has shown its power in all sectors, from medical treatment, medicine and vaccine development to prevention and control measures.”8．What can we know about the new therapy according to paragraph 1 and paragraph 2? A．It’s the first way to treat COVID-19.B．It dramatically improves the survival rate of patients.C．It takes researchers 10 years to develop the new drug.D．It was developed by the team from one of China’s top universities.9．Which statement does the author probably agree with?A．Only medical workers can take this drug.B．Antibodies stop spike proteins entering a cell.C．The new drug takes effect after a period of use.D．The new drug can protect people from infection for life.10．What can be inferred from the last paragraph?A．It is easy to produce the drug.B．The new drug has been put into use.C．Zhang thought highly of the power of science.D．China is the first country to use technology to fight disease.11．Where does the text probably come from?A．A textbook.B．An educational magazine.C．A medical journal.D．A tourist guide.As people get older, the types of friends they have tend to change. As young adults, humans have a lot of friends. With age, they often prefer to spend their time with just a few close, positive individuals. Researchers long believed that this change was unique to humans, but a new study finds that chimps also have similar tendencies.One explanation for the humans to get picky about social connections has to do with awareness of our limited life span. “People monitor how much time we have left in our life and choose emotionally-fulfilling relationships in old age,” says one of the study's lead authors Alexandra G. Rosati, a psychologist at the University of Michigan. As people age, they don’t want to be surrounded by a large group of negative friends, but would prefer to be near a handful of optimistic individuals.Rosati and her colleagues were curious whether chimps would show similar features even though they don’t seem to be aware of their upcoming death. Researchers used 78, 000 hours of observations made over 20 years from the Kibale Chimpanzee Project in Uganda. The data looked at the social interactions of 21 male chimps between 15 and 58 years old. The researchers only studied male chimps because they show stronger social bonds and have more social interactions than female chimps.Researchers found that wild chimpanzees share a similar pattern. “They interact with others in more positive ways as they get older. Younger adults, in contrast, show more aggression and were more likely to form one-sided relationships where their partner did not reciprocate. ”says Rosati. For example, the older chimpanzees would sit close to theirlong-time companions and groom (给……梳毛) each other, while younger chimps had more one-sided relationships where they would groom a friend, but the action wasn't returned. The study was published in the journal Science.“This aging pattern may be the result of shared changes in our abilities to manage our emotions with age,” Rosati says. “This shared pattern between chimpanzees and humans could represent an adaptive response where older adults focus on important social relationships that provide benefits and avoid interactions that have negative consequences as they lose competitive fighting ability.”12．Why do humans change their preference for friends in old age?A．They don’t like making new friends.B．Their friends pass away one by one.C．They adapt to the changes in nature.D．They know their life is running out.13．What is the purpose of Paragraph 3?A．To show the study was done scientifically.B．To show how scientists tried to prove their assumption.C．To show how hard it was to observe the chimps.D．To show male chimps are unaware of upcoming death.14．What does the underlined word “reciprocate” in Paragraph 4 mean?A．Repay their kindness.B．Take care of them.C．Get along well with them.D．Sit close to them.15．Which can be a suitable title for the text?A．People Prefer Positive Partners in Old AgeB．Positive Bonds Benefit Chimps in Many WaysC．Aging Chimps like Us Get Picky About FriendsD．Chimps Share Similar Tendencies with Humans二、七选五Small talk. Chitchat. These are the short conversations we have at parties, while we wait in line at the store, at family events or work. ____16____ Often we have to make small talk with complete strangers.Many people find these small conversations about random topics difficult. Some people say they hate it. ____17____They may even call it idle chitchat or idle chatter, meaning it doesn't do anything. They consider small talk not important.____18____ These exchanges can open doors that may lead to larger, more meaningful conversations. When you first meet someone or talk to someone you don't know well, it would be awkward to begin a conversation about a really deep topic such as war, politics or the meaning of life. Small talk also gives you the chance to decide if you want to know that person better-or not. Let's say you make small talk with someone at a party. ____19____You may not want to build a friendship with them unless you really, really love cats.Chitchat can also increase your feeling of understanding, or empathy, toward people you know but not well. Chatting with a colleague about their child may help you to understand more of their life outside the office. ______20______A．However, small talk is important.B．And small talk may make us happier.C．But they only want to talk about cats.D．Others say small talk is a waste of time.E．This could help build healthy work relationships.F．However, some people are not good at small talk.G．Sometimes we make small talk with people we already know but not well.三、完形填空I went to the beach nearby.
