2015-2016学年北京市海淀区高三（上）期末英语试卷学校:___________姓名：___________班级：___________考号：___________I、单选题(本大题共15小题，共15.0分)1.We need to master this technology immediately，______ we will fall behind．（）A.butB.orC.soD.and【答案】B【解析】答案：B根据句意，"We need to master this technology immediately""我们必须掌握技术"可知，"or"意为"否则的话"符合题意．"but"表示转折，so意为因此，and并列连词．我们需要立即掌握这个技术，否则我们会落后．考查连词，考生需联系上下文做出判断．2.---Jack，you look so great！---Thanks!I have lost 20pounds since I ______ my personal trainer six months ago．（）A.hired B.have hired C.hire D.had hired【答案】A【解析】答案是A．考查动词的时态，由于这是一个由since引导的时间状语从句，故主句用一般过去时，从句用现在完成时．根据句意，可知答案选A…-Jack你真棒．-谢谢！自从六个月前我聘请了我的私人教练，我已经见到了20磅了．高考题目对时态的考查是重点，谓语动词要与时间状语保持一致，时态与时间是密不可分的，各种时态却要受到时间和语言环境的限制，根据题干提供的时间或者时间状语体现的时间来判断句子的时态是最直接的解题方法，扎实的语法功底加上准确的理解至关重要3.______ my father doesn't say a lot in daily life，he gives me much love and affection．（）A.BecauseB.WhenC.AlthoughD.If【答案】C【解析】答案C．because"因为"，引导原因状语从句．when"在…时候"，引导时间状语从句．although"尽管，虽然"，引导让步状语从句．if"如果"，引导条件状语从句．分析可知前后两句话之间是逻辑上的"让步"关系，再结合句子所表达的意思可知答案选C．虽然我的父亲在日常生活中言语不多，但他给了我很多的爱和关怀．本题考查从属连词的用法．连词的用法辨析，要注意分析主从句之间的逻辑关系，再确定相应的连词，同时注意不同的连词的语义及用法区别．4.Yesterday we went to the library to do some reading，only to find that it ______．（）A.had closedB.had been closedC.wil closeD.will be closed【答案】B【解析】答案：B．根据时间状语Yesterday可知，是指过去的事实，而图书馆关门应该是在我们去之前，所以为过去的过去，应该使用过去完成时，而it与close之间我逻辑上的动宾关系，需要使用被动语态；故选B．昨天，我们去图书馆读书，却发现图书馆早已经关门了．过去完成时态表示过去的过去，时间状语是过去的参照时间．和现在完成时态不同的是，现在完成时态的参照时间是现在．学习时，要注意区分．5.Helen ran out of the classroom in tears，but no one knew ______ she was so sad．（）A.whenB.whetherC.thatD.why【答案】D【解析】答案：D．根据no one knew 说明后面整句是宾语从句，结合句意，海伦流着泪冲出了教室，但没人知道她为什么如此地伤心．因此宾语从句she was so sad缺原因状语，故选D海伦流着泪冲出了教室，但没人知道她为什么如此地伤心．本题考查宾语从句的连接词，在充分分析句型基础上便能选出正确答案．6.The traffic in Beijing will be better when Subway Line 16 ______ into service．（）A.would be putB.was putC.will be putD.is put【答案】D【解析】答案是D．本题考查被动语态．根据句意判断，"Subway Line 16"和"put"之间是被动关系；由主句的将来时判断，Subway Line 16是将被投入使用，排除A和B；该句是when 引导的时间状语从句，时间状语从句中往往用一般现在时表示将来，故选D．当16号地铁投入使用后北京的交通将会好转．本题考查被动语态，要分析主语和动词之间的关系，联系动词本身的特定用法；在掌握被动结构的基本形式"be/get+过去分词"的基础上理解不同时态的被动语态的结构，最后进行综合判断．7.---Henry，can you go to the concert tonight？---I'm afraid I can't．I will give the ticket to ______ wants to enjoy it．（）A.someoneB.whomeverC.everyoneD.whoever【答案】D【解析】答案：D．根据I will give the ticket to，说明后面整句是介词后的宾语从句，而宾语从句wants to enjoy it可知句子不完整，缺主语成分，whomever无论是谁，作宾语，排除B，选项AC后应加who，定语从句，故选D．---亨利，你今晚去听音乐会吗？---我恐怕不能．我将把票给无论是谁想要欣赏音乐会的人．本题考查宾语从句，在在充分分析句型基础上，同时熟知疑问词加ever及定语从句的基础上便不难选出此题答案．8.In December of 2015，the Second World Internet Conference was held in Wuzhen，______ theme is to ensure peace and security in cyberspace．（）A.whoseB.whichC.whenD.where【答案】A【解析】答案A根据句子分析可知，___theme is to ensure peace and security in cyberspace是非限制性定语从句，可知在从句中缺少定语，故用whose，表示"…的"，根据句意，可知选A．2015年12月份，第二届世界互联网大会在温州举行，它的主题是维护网络安全和稳定．本题考查非限制性定语从句．考生需掌握非限制性定语从句的特征并结构具体语境做出判断．9.______ your own needs is as important as learning to express your emotions．（）A.UnderstandB.UnderstandingC.UnderstoodD.Having understood【答案】B【解析】答案是B．本题考查动名词做主语．分析句子结构发现，谓语动词is前______ your own needs 在句中充当主语，而动词能充当主语的形式是动名词和动词不定式，A是动词原形，C是过去分词或过去式，都不能做主语，所以排除A和C；D项可以是动名词的完成式，动名词的完成式要强调动名词的动作在谓语动词之前，而本题中没有时间上的先后关系，所以排除D；由此分析得出答案是B．理解你的需要与学习表达情感一样重要．对于非谓语动词的选择，首先要根据句子的结构判断句中缺少的是谓语动词还是非谓语动词；如果是非谓语动词，在理解非谓语动词的基本用法的基础上再根据句子的结构做出判断．10.It takes a long time to restore nature_______ it is damaged．（）A.sinceB.unlessC.onceD.until【答案】C【解析】答案：C．根据选项since自从…，unless除非…，once一旦，until直到…，再结合句意，一旦被破坏，要花很长时间才能恢复自然，可知此处缺少了一个引导时间状语从句的连接词，故C正确．一旦被破坏，要花很长时间才能恢复自然．本题考查时间状语从句的连接词，在充分分析句型再结合语义的基础上便能选出正确答案，同时要注意其他选项的意思，11.It has been foggy for five days．How I wish it______ sunny now!（）A.would beB.wereC.had beenD.is【答案】B【解析】答案是B．本题考查wish引导的宾语从句．wish引导的宾语从句往往用虚拟语气，与现在事实相反的愿望用过去时，be 动词用were；与过去事实相反的愿望用过去完成时；与将来事实相反的愿望用could/would+do；根据本题题干中的now可知是与现在事实相反的愿望，所以答案是B．已经连续五天多雾了．我多么希望现在是晴天．在掌握虚拟语气的规则的基础上，判断题干属于什么类型的虚拟，然后根据语境，选用恰当的动词形式表达虚拟．12.When someone turns away his body，it means impatience and a desire ____ a conversation．（）A.to escapeB.escapedC.escapingD.having escaped【答案】A【解析】答案是A．本题考查不定式做定语．题干中名词desire后面的escape充当定语，表示"渴望做…"，常常用动词不定式短语做desire的定语，构成"a desire to do"；过去分词做定语表示被动，不符合句意，所以排除B；现在分词完成式不做定语，所以排除D；现在分词一般式做定语表示"正在进行"，且单个的分词做定语必须放在被修饰的词的前面，所以排除C，答案选择A．当某人转过他的身子，那就意味着不耐烦以及想逃避一个对话．首先判断选项中的动词在句中是以谓语还是非谓语形式出现，然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断．13.Drivers are supposed to limit the speed in neighborhoods because children ____ be playing there．（）A.shouldB.mustC.mayD.would【答案】C【解析】答案是C．本题考查情态动词的辨析．should应该；must必须；may也许；would会．根据句意，"也许"有孩子在附近玩，所以驾驶员开车要限速，所以答案选C．在附近开车应该限速因为小孩子们也许会在周围玩．要在正确理解情态动词的基本含义的基础上，整体理解语境中的情感态度，做出合理的判断．14.It's bad for your eyes if you keep them ______ on the screen for a long time．（）A.fixedB.fixC.fixingD.having fixed【答案】A【解析】答案：A 句中fix作keep的宾语补足语，fix与them之间构成动宾关系，要用表示被动的过去分词．故选A．你如果眼睛长时间盯着屏幕会对眼睛有害的．过去分词是非谓语动词的一种，用法很灵活，分为简单式done（表示与谓语同时或几乎同时发生的动作）；完成式having been done（表示先于谓语的动作）．学习时，要把握其用法特征：表示被动和完成．同时还要注意区分现在分词和不定式．15.In ______ hottest reality show Running Man III，Luhan is ______ only new member．（）A.a；不填B.a；anC.the；theD.the；不填【答案】C【解析】答案是C．本题考查定冠词的用法．第一空特指真人秀"奔跑吧，兄弟（3）"，所以用the，排除A和B．第二空考查"the only"表示"仅有的，唯一的"；所以判断答案是C．在最热的真人秀奔跑吧，兄弟（3）中，鹿晗是唯一的新成员．掌握冠词要关注两大方面：一是积累有关不定冠词、定冠词和零冠词的相关的规则；二是积累特掌殊的短语．II、完形填空(本大题共20小题，共30.0分)A eed a DayIt was a busy day as usual．I was making sandwiches and

daughter Kelly is a cautious person．She needs to warm up to situations，is hesitant to try new things．When with close friends，she becomes a leader who laughs loudly and chants，"Girls rule，boys drool．"But when that comfort zone is not around her，she is shy and nervous．This has been challenging for me at times．"Shy"is not a word that I think has ever been used to describe me．But this has been a year of firsts for my girl that has filled her with a new sense of confidence．This year she moved to lap lane in swimming where she was preparing for a swim team．This year she learned to ride a bike without training wheels．And this year she completed her first kids'triathlon （三项全能）．On Saturday，with a thunderstorm coming soon and my son's birthday party later in the day，we all went out in the dark of the morning for Kelly to participate in her first triathlon．We practiced transitions from swim to bike to run with her，we got all the equipment she'd need，and we kept talking about the race．But as we waited the two hours for the older kids to finish before her turn，she held my leg a little harder and told me she loved me a few too many times．She was nervous but trying to keep it together．And then it was her turn．From the second she jumped into the water，my heart soared．My daughter transformed into the most confident human being I had ever seen．She dominated （主宰）that swim，crushed that bike ride and ran to the finish with the biggest smile on her face．I can honestly say that I never felt so proud of someone in my entire life．It wasn't because she did a sport or anything like that．It was because she was afraid of something and conquered（克服）that fear with confidence and a fire I hadn't seen before．All day I would find myself just looking over at her and smiling．She might be wearing the finalist medal but I felt like I won that day．I won the chance to see my girl shine．Shine on，sweet baby．36.Kelly is nervous when A．A.situations are new to herB.boys are around herC.she changes into a

have a scent？When someone is hapy，can you smell it？You can usually tell when someone is happy based on seeing them smile，hearing them laugh or perhaps from receiving a big hug．But can youalso smell their happiness？Surprising new research suggests thathappiness does indeed have a scent，and that the experience of happiness can be transmitted through smell，reports Phys．org．For the study，12young men were shown videos meant to bring about a variety of emotions while researchers gathered sweat samples from them．All of the men were healthy and none of them were drug users or smokers，and all were asked to abstainfrom drinking or eating smelly foods during the study period．Those sweat samples were then given to 36equally healthy young women to smell，while researchers monitored their reactions．Only women were selected to smell the samples，apparently because previous research has shown that women have a better sense of smell than men and are also more sensitive to emotional signaling-though it's unclear why only men were chosen to produce the scents．Researchers found that the behavior of the women after smelling the scents-particularly their facial expressions-indicated a relationship between the emotional states of the men who produced the sweat and the women who sniffed them．"Human sweat produced when a person is happy brings about a state similar to happiness in somebody who breathes this smell，"said study co-author Gun Semin，a professor at Koc University in Turkey．This is a fascinating finding because it not only means that happiness does have a scent，but that the scent is capable of transmitting the emotion to others．The study also found that other emotions，such as fear，seem to carry a scent too．This ensures previous research suggesting that some negative emotions have a smell，but it is the first time this has proved to be true of positive feelings．Researchers have yet to isolate（分离）exactly what the chemical compound for the happiness smell is，but you might imagine what the potential applications for such a finding could be．Happiness perfumes，for instance，could be invented．Scent therapies（香味疗法）could also be developed to help people through depression or anxiety．Perhaps the most surprising result of the study，however，is our broadened understanding of how emotions get communicated，and also how our own emotions are potentially managed through our social context and the emotional states of those around us．43.What is the main finding of the new research？______A.Men produce more sweats．B.Negative emotions have a smell．C.Pleasant feelings can be smelt out．D.Women have a better sense of smell．44.The underlined part"abstain from"in Paragraph 3probably means ______ ．A.avoidB.practiceC.continueD.try45.What is the application value of the new research？______A.Perfumes could help people understand each other．B.Some smells could be developed to better our mood．C.Perfumes could be produced to cure physical diseases．D.Some smells could be created to improve our appearance．46.We can learn from the last paragraph that ______ ．A.happiness comes from a scent of sweat。

2015-2016学年北京市海淀区高一（上）英语期末考试一、阅读理解（共10小题；共20分）AThe Corn PlantingHatch is nearly seventy. He and his wife had a son, Will, who was a fellow always cheerful, bright, alert and a great favorite with all of us.After high school, Will went to Chicago, where he became a student in the art Institute. Another young fellow, Hal, from our town was also a student at the University in Chicago. They got together and had a good many long talks. I got it from Hal that in Chicago, Will's straightforwardness made him popular with all the young fellows.After Hal graduated, he came home and got a job. He used to go quite often to see Will's father and mother. The talk was always of Will. Hal said Will's parents were like two children wanting to know every little detail Hal could remember about their son's life in the big city.It was a spring night when Hal got a wire. Will had been killed in a car accident. We went along to take the message to Hatch and his wife. Hal did knock and old Hatch came to the door. Hal told him everything right into old Hatch and his wife. Old Hatch didn't say a word and stood there. The door went shut again with a bang. Suddenly, after a long time, the old man got a hand corn-planter and his wife got a bag of seed corn, and in the moonlight, that night, after they got that news, they were planting corn. They did a row across the field, and then at the end of each row they knelt side by side by the fence. The whole thing went on in silence.It was the first time in my life I ever understand something about the connection between certain people and the earth—a kind of silent cry, down into the earth, of those two old people, putting corn down into the earth. It was as though they were putting death down into the ground that life might grow again.1. What made Will popular in the Art Institute?A. His artistic talent.B. His good character.C. His family background.D. His friendship with Hal.2. According to paragraph 3, Will's parent .A. were very childrenB. were very talkativeC. were eager to know about their son's lifeD. were fond of the life in the big city3. On hearing the news of his son's death, Hatch .A. planted cornB. pushed Hal outC. burst into tearsD. fell on the floor4. According to the last paragraph, the old couple's behavior was to .A. reduce their painB. have a better harvestC. memorize their sonD. pray for their son's rebirthBThe Importance of After-school ProgramsIn the old model of teaching and molding the behavior of youngsters and teens, the home and the school had always been the two institutions tasked to provide counseling, support, learning and providing avenues for character development. With the increasing number of kids who are not able to go to school for various reasons from poverty to disenfranchisement, the need for alternative methods to help children outside schools is being brought into the spotlight. In this article, we explore some of the methods of after-school education and character building that is pivotal to mold in young minds despite the inadequacy of education institutions to open its doors to everyone.Here are some of the more common after-school and beyond-school activities that can be found in many communities all over the world.Sports Clubs. Sports has long been known as a key vehicle for molding minds and teaching them the value of teamwork, sacrifice, determination, hard work and many other important values. Beyond school, there are many sports clubs that offer an avenue for kids to bond together doing things that they are passionate about. Common examples in this area cover sports such as basketball, baseball, soccer, swimming, and more recent trends like skateboarding and surfing to name a few.Performing Art Clubs. While some kids easily gravitate towards sports, there are others who feel more at home on-stage or in a performing arts training room. Common examples include drama, ballet, dance, The Glee Club, painting classes, piano and violin lessons and many others. These classes hammer home the importance of being confident in your talents and taking pride in being able to perform in front of a crowd. Many of the best Hollywood actors and actresses that we know today started in school and community plays where they discovered their calling for the performing arts.Remedial Classes. While these are not necessarily considered to be part of school, these are intended to provide extra classes to help kids with their lessons. Common examples are those in difficult subjects like literature and reading, or sciences and mathematics.After School Nutrition Programs. Especially in impoverished communities where nutrition is a major problem, there are many organizations that provide students with warm and nutritious meals before they are allowed to go home. These supplementary feeding programs are essential activities to ensure that proper nutrition is maintained despite the tough financial standing of families in a specific neighborhood.5. If you are confident in yourselves, you can participate in .A. Performing Art ClubsB. Sports ClubsC. Remedial ClassesD. After School Nutrition Programs6. The After-school Programs now are intended for .A. body buildingB. character buildingC. helping kids in neighborhoodD. helping kids outside school7. Where can most probably we find the passage?A. On a notice board.B. On a university website.C. In an educational magazine.D. In an English teaching book.CReading books has always been regarded among the charms of cultured life and is respected and envied by those who rarely give themselves that enjoyment.This is easy to understand when we compare the difference between the life of a man who does no reading and that of a man who does. The man who doesn't have the habit of reading is imprisoned in his immediate world, in respect to time and space. He is limited to contact and conversation with a few friends, and he sees only what takes up a book, he immediate neighborhood. From this prison there is no escape. But the moment he takes up a book he immediately enters a different world, and if it is a good book, he is immediately put in touch with one of the best talkers of the world. This talker leads him on and carries him into a different country or age, or unburdens to him some of his personal regrets, or discusses with him some aspect of life that the reader knows nothing about.But there is more to it than this. The reader is always carried away into a world of thought and reflection. Even if it is a book about physical events, there is a difference between seeing such events in person or living through them, and reading about them in books. The best reading is therefore that which leads us into deep though, and not that which is merely the report of events.The great are mainly concerned with getting reports about events and happening without value for further thinking.The poet Huang Shanku said, "A scholar who hasn't read anything for three days feels that his talk has no flavor, and his own face becomes hateful to look at in the mirror." What he means, of course, is that reading gives a man a certain charm, which is the entire aim of reading, and only reading with this purpose can be called an art. One doesn't read to "improve one's mind," because when one begins to think of improving his mind, all the pleasure of reading is gone. He is the type of person who says to himself, "I must read Shakespeare, so I can become an educated man". I'm sure that man will never become educated. Anyone who reads a book with a sense of obligation does not understand the art of reading.8. According to the passage, what is the advantage of reading?A. We can escape from our immediate world.B. We can experience the same feeling as the author.C. We can be led to thinking and reflecting.D. We can reduce our own regrets in life.9. The poet Huang Shanku is quoted to explain .A. the main pleasure of readingB. the status of reading as an artC. the importance of improving one's mindD. the influence of reading on one's appearance10. The author wants to show the importance of reading for .A. mastery of skillsB. enrichment of soulC. improvement of mindD. collection of information二、阅读与表达(混合式)（共10小题；共20分）The classroomAt the sight of my old professor, I froze.I had not seen him in sixteen years. I suddenly felt unprepared for this meeting—I hoped that he hadn't noticed my arrival. But Morrie was smiling at me, waiting for me to go inside.The sun beamed in through the window, lighting up the floor. We had been talking there for nearly two hours. The phone rang yet again and Morrie asked his helper, Connie, to get it. She had been writing the callers' names in Morrie appointment book. People who wanted to have a talk with him. A discussion group.It was clear I was not the only one interested in visiting my old professor—the Morrie hotline "Nightline" had made him well-known—but I was impressed with all the friends that Morrie seemed to have. I though about my friends in college. Where had they gone?"You know, Mitch, now that I'm dying. I've become much more interesting to people.""You were always interesting.""Ho," Morrie smiled, "You're kind."No, I'm not, I thought."Here's the thing," he said, "People see me as a bridge. I'm not as alive as I used to be, but I'm not yet dead. I'm sort of ……in-between."He coughed, then smiled again. "I'm on the last great journey here-and people want me to tell them what to pack."The phone rang again."Morrie, can you talk?" Connie asked."I'm visiting with my old friend now," he announced, "Let them call back."I cannot tell you why he received me so warmly. I was hardly the best student ho had left him sixteen years earlier. Had it not been for "Nightline", Morrie might have died without ever seeing me again. I had no good excuse for this. I had become too wrapped up in my own life. I was busy.What happened to me? I asked myself. Morrie's voice took me back to my university years, when I though rich people were evil, a shirt and tie were prison clothes, and life without freedom to travel around the world was not a good life at all. What happened to me?I traded lots of dreams for a bigger paycheck and I never even realized I was doing it. Yet here was Morrie talking with the wonder of our college years, as if I'd simply been on a long vocation."Have you found someone to share your heart with?" he asked."Are you giving to your companies?Are you at peace with yourself?""Are you trying to be as human as you can be?"I hesitated, wanting to show I had been struggling with such questions. What happened to me? I once promised myself I would never work for money, that I would live in beautiful and inspirational places.Instead, I had been in the same city for ten years now, at the same workplace, visiting the same shop. I was thirty-seven, tied to computers and cell phones. I wrote articles rich athletes who, for the most part, could not care less about people like me. I was no longer young. I did not have long discussions about the meaning of life.My days were full, yet I remained, much of the time, unsatisfied.What happened to me?任务一：根据短文内容，判断正误，正确的为T，错误的为F。
