2020-2021上学期兰考三高卫星实验部第一次周练试卷高二英语阅读理解AIn the coming months,we are bringing together artists from all over the globe,to enjoy speaking Shakespeare's plays in their own language,in our Globe,within the architecture Shakespeare wrote for.Please come and join us.National Theatre of China Beijing|ChineseThis great occasion(盛会)will be the national theatre of China's first visit to the UK.The company's productions show the new face of21st century Chinese theatre.This production of Shakespeare's RichardⅢwill be directed by the National's Associate Director，Wang Xiaoying.Date&Time：Saturday28April，2.30pm&Sunday29April，1.30pm&6.30pmMarjanishvili Theatre Tbilisi l GeorgianOne of the most famous theatres in Georgia，the Marjanishvili，founded in1928，appears regularly at theatre festivals all over the world.This new production of As You Like It is helmed(指导)by the company's Artistic Director Levan Tsuladze.Date&Time：Friday18May，2.30pm&Sunday19May，7.30pmDeafinitely Theater London/British Sign Language(BSL)By translating the rich and humourous text of Lover's Labour's Lost into the physical language of BSL，Deafinitely Theater creates a new interpretation of Shakespeare's comedy and aims to build a bridge between deaf and hearing worlds by performing to both groups as one audience.Date&Time：Tuesday22May，2.30pm&Wednesday23May，7.30pmHabima National Theatre Tel Aviv/HebrewThe Habima is the centre of Hebrewlanguege theatre worldwide.Founded in Moscow after the 1905revolution，the company eventually settled in Tel Aviv in the late1920s.Since1958，they have been recognized as the national theatre of Israel.This production of Shakespeare's The Merchant of Venice marks their first visit to the UK.Date&Time：Monday28May，7.30&Tuesday29May，7.30pm21.Which play will be performed by the National Theatre of China?A．RichardⅢ.B．Lover's Labour's LostC．As You Like It D．The Merchant of Venice22.What is special about Deafinnitely Theatre?A．It has two groups of actors.B．It is the leading theatre in London.C．It performs plays in BSL.D．It is good at producing comedies.23.When can you see a play in Hebrew?A．On Saturday28April.B．On Sunday29April.C．On Tuesday22May.D．On Tuesday29May.BAn old man lived alone in Minnesota.He wanted to spade(铲)his potato garden,but it was hard work.His only son,who would have helped him,was in prison.The old man wrote a letter to his son and mentioned his situation:Dear son,I am feeling pretty bad because it looks like I won’t be able to plant my potato garden this year.I hate to miss doing the garden,because your mother always loved planting time. I’m just getting too old to be digging up a garden plot.If you were here,all my trouble would be over.I know you would dig the plot for me,if you were not in prison.Love,Dad Shortly,the old man received this telegram:“For Heaven’s sake,Dad,don’t dig up the garden!!That’s where I buried the GUNS!!”At4am the next morning,a dozen FBI agents（联邦调查局）and local police officers showed up and dug up the entire garden without finding any guns.Confused,the old man wrote another note to his son telling him what had happened,and asked him what to do next.His son’s reply was:“Go ahead and plant your potatoes,Dad.It’s the best I could do for you from here.”No matter where you are in the world,if you have decided to do something deep from your heart,there is nothing that can stop you from doing it.It is the thought that matters,not where you are or who you are.24.Why did the old man write a letter to his son?A.To show his love for him.B.To ask about his situation.C.To tell about his trouble.D.To give him some advice.25.The police officers dug up the old man’s garden_______.A.to search for some goldB.to search for some gunsC.to offer him some helpD.to give him a surprise26.After the police officers left,the old man felt_______about what had happened.A.puzzledB.worriedC.satisfiedD.excited27.We can infer from the story that the son is______.zyB.honestC.cleverD.braveCWhen it comes to helping developing countries,we often think about offering money in order that they can build schools and hospitals,buy food and medicine,or find clean water supplies. These seem to be the most important basic needs in their lives.However,it's far from enough.We have to come up with better ideas.A man called Nicholas Negroponte invented a cheap laptop computer,which he decided to invent after he visited a school in Cambodia.The laptop which Mr.Negroponte has designed is not the same as the normal one that you can buy in the shops.One difference is that it will be covered in rubber so that it is strong and won't be damaged easily.As an electricity supply can be a problem in developing countries,the computer also has a special handle in order that children can wind the computer up to give it extra power just as easy as setting a clock.This special laptop computer will cost less than100US dollars and Mr.Negroponte wants to produce as many as15million laptop computers in the first year.The idea is that these computers will help the children's education as they will be able to access the Internet.These computers might not benefit the people in developing countries immediately,but by improving children's education they should help people to find their own solutions to their problems in the long term.Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again in the UK and probably in many other countries too,millions of mobile phones are thrown away every year.The waste crested by throwing away these old phones is very bad for the environment,so it seems to be an excellent idea to achieve two important goals at the same time.We will reduce the waste we produce and help others,in other words,we will be able to"kill two birds with one stone"and that is always a good thing.28.The underlined phrase"wind up"in paragraph2means.A．吹风B．给……上紧发条C．拆开D．带走29.The laptop computer that Mr.Negroponte has designed.A．will be damaged much easier than the normal oneB．has a special handle to access the InternetC．is cheap and can run with extra powerD．can be helpful to find the people's own solutions30.Mr.Negroponte's cheap computer is mentioned in the passage to.A．illustrate the kindness of people in the developed countriesB．tell us what high technology can help peopleC．show how to find business opportunities in developing countriesD．give an example of how to help developing countries31.Which is the best idea the author gives us to help the developing countries?A．We need to think about more ways to help people in developing countries，not just throw money at the problem.B．We should spend much money helping people in developing countries build more schools and hospitals.C．We should think about giving help to developing countries by giving them all we have.D．We should help the people in developing countries by improving children's education immediately.DGetting rid of dirt,in the opinion of most people,is a good thing.However,there is nothing fixed about attitudes to dirt.In the early16th century,people thought that dirt on the skin was a means to block out disease,as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in.A particular danger was thought to lie in public baths.By1538,the French king had closed the bath houses in his kingdom.So did the king of England in1546.Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way.Henry IV,King of France,was famously dirty.Upon learning that a nobleman had taken a bath,the king ordered that, to avoid the attack of disease,the nobleman should not go out.Though the belief in the advantage of dirt was long-lived,dirt has no longer been regarded as a nice neighbor ever since the18th century.Scientifically speaking,cleaning away dirt is good to health.Clean water supply and hand washing are practical means of preventing disease.Yet,it seems that standards of cleanliness have moved beyond science since World WarⅡ. Advertisements repeatedly sell the idea:clothes need to be whiter than white,cloths ever softer, surfaces to shine.Has the hate for dirt,however,gone too far?Attitudes to dirt still differ hugely nowadays.Many first-time parents nervously try to warn their children off touching dirt,which might be responsible for the spread of disease.On the contrary,Mary Ruebush,an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system.And the latter position is gaining some ground.32.The kings of France and England in the16th century closed bath houses because.A.they lived healthily in a dirty environment.B.they thought bath houses were too dirty to stay inC.they believed disease could be spread in public bathsD.they considered bathing as the cause of skin disease33.Which of the following best describes Henry IV’s attitude to bathing?A.disapprovingB.Curious.C.Approving.D.Uninterested.34.How does the passage mainly develop?A.By providing examples.B.By making comparisons.C.By following the order of time.D.By following the order of importance.35.What is the author’s purpose in writing the passage?A.To stress the role of dirt.B.To introduce the history of dirt.C.To call attention to the danger of dirt.D.To present the change of views on dirt.第二节(共5小题：每小题2分，满分10分)Nowadays more and more Chinese parents invest large sums of money to send their children to study abroad.With countless difficulties to face and solve while studying abroad, overseas students should pay attention to the following things.●Adjust mental attitudes.Experts consider psychological preparation as the most important thing for students studying abroad to consider.___36___●Adapt to new learning methods.Chinese students have got accustomed to the domestic exam-oriented education style.They will face changes in the educational system while studying abroad.___37___●Be willing to communicate.With no relatives or friends by their sides,the first feeling of Chinese students is loneliness,which makes it especially important to learn to develop relationships with people around them.___38___Foreigners really like children of this kind and are willing to help them.●___39___Students should ask related teachers to help make plans consistent with their practical condition.Learning plans require students to hold on to the primary direction of their overseas studies and arrange learning content for each course and semester.After the plan is made, they should strictly keep to it.●Develop self-motivation for learning.Foreign children are used to learning by themselves in or after class.___40___So studying abroad requires that they should adapt to overseas studies as soon as possible and try their best to learn actively and independently.A.Students must know they are going abroad to study and not for leisure.B.Try to find more solutions to adjusting to the open education.C.Make and stick to learning plans.D.However,Chinese children are used to teacher-centered education.E.They should go out of their way to be friendly and strike up conversations.F.Help children with financial planning.G.Students should prepare themselves for the school完型填空（共20小题；每小题 1.5分，满分30分）When Dave was eighteen,he bought a secondhand car for200dollars so that he could travel to and from work more__41__than by bus.It

One afternoon, my brother grabbed me in the yard, and I felt some kind of pop. About an hour later, I couldn't get up from a chair. Over the weekend, my joints(关节) swelled up. My mother took me to the hospital. It took nearly six months to check what was wrong with me. Then I was put on treatment. But I had so much joint damage that I couldn't run like I used to.My dad was a serious golfer. One d ay he said, “Let's try golf.” He carried me onto the course. Seeing him hit those good shots made me want to do it too.It wasn't easy at first, because I had a lot of pain in my hands. I'd played golf, but it had never really caught my interest—it was too quiet for me. But I was happy to be outside, to have a chance of competing again, and I fell in love with it.Later I made the high school team, but I got frustrated when I didn't win, so I worked harder. Golf was the most challenging game I'd ever played.I got a golf scholarship to the University of South Carolina and turned professional after I graduated. I still take medication, and I'm stiff and in pain sometimes. But I've got used to that.I probably wouldn't be a professional athlete if I hadn't got sick. The experience taught me patience, and I learned to take nothing for granted. I know how happy I am to do what I do.24．What do we know about the author from Paragraph 1?A．He was born with swelled joints.B．His joints healed very quickly.C．He completely recovered after the treatment.D．The cause of his disease was found out six months later.25．What inspired the author to play golf at the beginning?A．His love for golf. B．His interest in sports.C．His father's good performance. D．His unwillingness to stay indoors.26．Which of the following is TRUE according to the passage?A．It was the author's brother who first became aware that he had a disease.B．Suffering a lot of pain in his hands, the author wasn't interested in playing golf at first.C．After founding a high school team, the author played harder and becameprofessional.D．The author thought he should cherish everything he had, even his disease.27．What would be the best title for the passage?A．Playing through pain B．The burden liftedC．A bitter fight D．Standing tallCChina's hot word, tuhao, may be in Oxford English Dictionary.In Chinese, tu means rude and hao means rich. In recent years, people use this term to describe those who spend money in an unreasonable way. The word became more popular with Apple's gold-colored iPhone, which is loved by China's rich people. The color b ecame known as “tuhao golden”. The word is now often used to refer to people who have money but lack taste.There are two other Chinese hot words: dama and No Zuo No Die, which may also be taken in the dictionary. Dama, meaning middle-aged women, was first used in the Western media by the Wall Street Journal. Thousands of Chinese women were buying a large amount of gold when the gold price had gone down. Another phrase No Zuo No Die, meaning if you don't do stupid things, they won't come back to bite you, is also very popular. Other words, such as Maotai, Chinglish and dim sum have also been included in the dictionary.BBC World News recently made a special program called “Tuhao, let's be friends！” “The frequent use of Chinglish by foreign media suggests th at foreign people are looking more to the lifestyle and popular culture of China，” says Zhang Yiwu, professor of Beijing University.What does this trend suggest about the Chinese language's influence?Xing Hongbing, a professor from Beijing Language and Culture University (BLCU) said “These show that Chinglish is now being accepted by the rest of the world and they play important roles in daily life of Chinese. Behind these Chinglish words and phrases are the Chinese culture. They are reflections of the changes and trends in the Chinese society and they help people from other countries to understand what's happening in China.”28．Which of the following words is NOT a hot Chinglish word?A．Dama B.KaraokeC．Tuhao D.Dim sum29．The word “dama” becomes so popular because ________.A．they are wealthy middle-aged womenB．they bought gold crazily when the price was downC．they made the gold price upD．they worked on the Wall Street30．According to the passage, Xing Hongbing agreed that ________.A．Foreigners want to know more about the culture of China from Chinglish.B．Chinglish hot words tell some funny things about China.C．Chinglish plays important roles in daily life of Chinese.D．Chinglish hot words are so vivid that people like using them a lot.31．What's the purpose of writing this article?A．To describe the hot words in Oxford English Dictionary.B．To explain the meanings of some Chinese hot words.C．To describe the use of Chinglish hot words and their influence.D．To show the different opinions about Chinglish hot words.DYou wake up in the mornings. The day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on the other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. Are you still in a wonderful mood? Impossible!Communicating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others' pity or respect.When you communicate with positive people, your spirit stays high and therefore more positive things are attracted. When the dagger (匕首) of a negative person is put into you, you will always feel down.Sometimes we have no choice but to communicate with negative people. It could be a co-worker or a relative. In this case, say what needs to be said as little as possible. Sometimes letting out your anger back to the negative person may make you feel good, but this will lower you to that same negative level and they won't feel ashamed of themselves about that.Negativity often affects happiness without even being realised. The negative words of another person at the start of a day can cling to (附着) you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.32．The purpose of the first paragraph is to________.A．make a comparison B．offer an evidenceC．introduce a topic D．describe a daily scene33．How can negative people affect us?A．By influencing our emotion.B．By telling us the nature of life.C．By changing our ways of thinking.D．By comparing their attitudes to life with ours.34．According to the passage, to reduce negative people's influences on us, we are advised to ________.A．change negative people's attitudes to lifeB．show our dissatisfaction with negative peopleC．make negative people feel ashamed of themselvesD．communicate with negative people as little as possible35．What is the author's attitude towards negative people?A．Favourable.B．Critical.C．Indifferent.D．Supportive.第二节(共5小题；每小题2.5分，满分12.5分)阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
