2011年天津市高考英语试卷解析版参考答案与试题解析第一部分:英语知识运用(共两节,满分15分)第一节:单项填空(共15小题,每小题1分,满分15分)1.(1分)We feel our duty to make our country a better place.( )A.it B.this C.that D.one【考点】GF:it 的用法.【分析】我们感觉使我们的国家变成一个更好的地方是我们的责任.【解答】答案:A.题干中动词feel的真正宾语是不定式to make our country a better place,it作形式宾语,代替此不定式,our duty作宾语补足语,构成"动词+it+n.+to do".故选A.【点评】此题考查it作形式宾语.it作形式宾语常用的结构如下:①feel/make/think/find/consider+it+n./adj./介词短语+to do②enjoy/like/love/dislike/hate+it+when﹣从句③appreciate it+if﹣从句④rely on/depend on/count on/see to it+that﹣从句2.(1分)Just a moment.I haven't finished packing my suitcase..It's high time we left for the airport.( )A.Go ahead B.Take it easyC.Hurry up D.That's fine【考点】JI:语言交际.【分析】﹣﹣稍等一会儿.我还没有装好旅行箱.﹣﹣快点.快到我们去飞机场的时间了.【解答】答案C.由空后的"快到我们去飞机场的时间了."可知此处应该催促对方抓紧时间.Go ahead."干吧,继续,开始";Take it easy."放松点,别紧张";Hurry up."快点,赶快";That's fine."没事,没关系".所以应该选择C.【点评】做这类题目,要根据选项的意义、用法及句意来做出正确的选择和判断.3.(1分)In the last few years thousands of films all over the word.( )A.have produced B.have been producedC.are producing D.are being produced【考点】F2:现在完成时的被动语态.【分析】在过去的几年里,全世界拍摄了成千上万部电影.【解答】答案:B 由"in the last few years"可知,句子应该用现在完成时.又由于films和produce之间是被动关系,故应该用现在完成时的被动语态.A、C项是主动语态;D项是现在进行时的被动语态,故都应该排除.B项符合题意,故选:B.【点评】考查现在完成时的被动语态,主要根据时间状语判断时态,然后再看句子的主语和动词之间是主动还是被动关系即可.4.(1分)On the next birthday.Ann married for twenty years.( )A.is B.has beenC.will be D.will have been【考点】EB:将来完成时.【分析】句意:到下一个生日,安将已经结婚20年了.【解答】答案:DOn the next birthday,是将来的时间;for twenty years是现在完成时的时间状语,所以用will have done表示到将来某一段时间已经完成的事.根据句意:到下一个生日,安将已经结婚20年了.故选D.【点评】本题考查将来完成时的用法,答题时要注意时间状语的暗示.5.(1分)regular exercise is very important.It's never a good idea to exercise too close to bedtime.( )A.It B.As C.Although

days,从句中不缺少主宾表定,所以用关系副词,where表地点,与题意不符,故选A.【点评】解答这类题型,要分析从句中句子成分是否齐全,如果齐全就用关系副词when、why、where,再根据先行词来确定.11.(1分)He was a good student and scored _________ average in most subjects.( )A.below B.of C.on

diseases吸烟会导致许多疾病是evidence的内容,是同位语从句,这句话又是一个完整的句子,故用that做连接词,只起连接的作用,不做任何成分,也不可以省略.故选C.【点评】本题考查同位语从句中that做连接词的用法,要分析句子的成分并结合具体的语境选择出正确选项.14.(1分)﹣﹣﹣I need to advertise for a roommate for next

可知"我"事实上并没有早点来,因此可推知第一句应该是一个虚拟语气的句子.因为讲述的是过去的事情,所以句子应借助于"would+have+过去分词"的形式.本句可以理解为:I would have come sooner if I had known that they were waiting for me.故选D.【点评】本题考查虚拟语气.解答此类题目首先根据上下文语境找到隐藏的条件,转换成if条件句中的虚拟语气来理解,然后判断是对哪种情况的虚拟,从而来确定谓语动词的形式.第二节:完形填空(共1小题:每小题1.5分,满分1.5分)16.(30分)阅读下面短文,掌握其大意,然后次哦能够16~35各题所给出的A、B、C、D四个选项中选出最佳选项.A Love Note To My MomWhen

D A.She wanted to study by herself.B.She fell in love and got married.C.She suffered from a serious illness.D.She decided to look after her grandma.43.What can we learn about the author from Paragraphs 4and 5? A AShe was buy yet happy with her family life.B.She ignored her guilty feeling for her sons.C.She wanted to remain a full﹣time housewife.D.She was too confused to make a correct choice.44.What dose the author mostly want to tell us in the last paragraph? B A.Failure is the mother of success.B.Little by little,one goes far.C.Every coin has two sides.D.Well begun,half done.45.Which of the following can best describe the author? A A.Caring and determine.B.Honest and responsible.C.Ambitious and sensitive.D.Innocent and single﹣minded.【考点】OB:人生感悟类阅读;P4:逻辑推理.【分析】本文讲述了作者从小充满梦想,并持之以恒付诸实践,将梦想变成现实.很多事情都要从量变到质变,不能着急,要持之以恒.生命就是个过程,伟大的梦想需要一步一步脚踏实地的完成.【解答】41.答案:C 细节理解题.由第一段第一句中的dreaming of sitting on a Supreme Court bench可知,作者去霍华德大学时就梦想着能够坐在美国联邦最高法院的长凳上,即她渴望成为一名法官.42.答案:D 细节理解题.由第二段第三、四句"I made the choice to withdraw from college to care for her.It meant that school and mypersonal dream would have to wait."可知,作者在大二时退学回家是为了生病的祖母.43.答案:A 推理判断题.由第四、五段的叙述可知,作者在家里虽然忙碌,但她的确非常快乐.由第五段第一句中的The hardest partwas feeling guilty about…可知B项的叙述是错误的;由第四段第四、五句可知作者并没有放弃自己的梦想去当全职家庭主妇,排除C项;由第四段倒数第二句中"Ihad only one choice:to find a way."可知,作者对于这个选择是果断的,并没有感到困惑,排除D项.44.答案:B 主旨大意题.最后一段的最后一句"Remember:little steps add up to big dreams."是该段的主题句,意思是:"不积跬步,难以至千里(每一小步都能积累成伟大的梦想)"与Little by little,one goes far."千里之行,始于足下."意思相同;.而Failure is the mother of success."失败是成功之母.";Every coin has two sides."凡事都有两面性.";Wellbegun,half done."好的开始是成功的一半."45.答案:A 推理判断题.由第二段作者在大二时退学回家照顾祖母可知,这表明作者是有爱心的;由倒数第二段作者用了21年多的时间最终取得大学学位,这表明作者是有决心的.【点评】这类文章一般描述的是某一件具体事情的发生发展或结局,有人物、时间、地点和事件.命题往往从故事的情节、人物或事件的之间的关系、作者的态度及意图、故事前因和后果的推测等方面着手,考查学生对细节的辨认能力以及推理判断能力.19.(12.5分)An idea that started in Seattle's public library has spread throughout America and beyond.The concept is simple:help to build a sense of community in a city by getting everyone to read the same book at the same tome.In addition to encouraging reading as a pursuit (追求)to be enjoyed by all,the program allows strangers to communicate by discussing the book on the bus,as well as promoting reading as an experience to be shared in families and schools.The idea came from Seattle librarian Nancy Pearl who launched (发起)the"If All of Seattle Read the Same Book"project in 1998.Her original program used author visits,study guides and book discussion groups to bring people together with a book,but the idea has since expanded to many other American cities,and even to Hong kong.In Chicago,the mayor(市长)appeared on television to announce the choice of To Kill a Mockingbird as the first book in the"One Book,One Chicago"program.As a result,reading clubs and neighbourhood groups sprang up around the city.Across the US,stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.The only problem arose in New York,where local readers could not decide on one book to represent the huge and diverse population.This may show that the idea works best in medium﹣sized cities or large towns,where a greater sense of unity(一致)can be achieved.Or it may show that New Yorkers rather missed the point,putting all their energyAnd passion into the choice of the book rather than discussion about a book itself.Ultinatel was Nancy points out,the level of sucicess is not meastured by how many people read a book,but by how many people are enriched by the process.or have enjoyed speaking to someone with whom they would not otherwise have shared a word.46.What is the purpose of the project launched by Nancy?

B①,由=﹣2即(x﹣c)x+(y﹣c)(y+c)=﹣2.将①代入化简得18x2﹣16xy﹣15=0,⇒y=代入①化简得c=>0.所以x>0,因此点M的轨迹方程为18x2﹣16xy﹣15=0B B(x>0).19.B【解答】解:(I)①当a=时,f(x)=lnx﹣x2.∴f′(x)=﹣x=,x∈(0,+∞),令f′(x)=0,解得x=2.当x变化时,f'(x),f(x)的变化情况如下表:B所以,f(x)的单调递增区间是(0,2),f(x)的单调递减区间是(2,+∞).证明:②由(I)知f(x)在(0,2)内单调递增,在(2,+∞)内单调递减.令g(x)=f(x)﹣f().由于f(x)在(0,2)内单调递增,故f(2)>f(),即g(2)>0.取x′=e>2,则g(x′)=<0.所以存在x0∈(2,x'),使g(x0)=0,即存在x0∈(2,+∞),使f(x0)=f().(II)证明:由f(α)=f(β)及(I)的结论知α<<β,从而f(x)在[α,β]上的最小值为f(a).又由β﹣α≥1,α,β∈[1,3],知1≤α≤2≤β≤3.故即从而≤a≤.20.B【解答】20、满分14分.(I)解:由,可得又b n a n+a n+1+b n+1a n+2=0,+a2n+2a2n+1=0,①(II)证明:对任意n∈N*,a2n﹣12a2n+a2n+1+a2n+2=0,②a2n+1+a2n+2+2a2n+3=0,③②﹣③,得a2n=a2n+3.④将④代入①,可得a2n+a2n+3=﹣(a2n﹣1+a2n+1)+1即c n=﹣c n(n∈N*)+1又c1=a1+a3=﹣1,故c n≠0,因此是等比数列.+a2k+1=(﹣1)k,(III)证明:由(II)可得a2k﹣1于是,对任意k∈N*且k≥2,有将以上各式相加,得a1+(﹣1)k a2k﹣1=﹣(k﹣1),即a2k=(﹣1)k+1(k+1),﹣1此式当k=1时也成立.由④式得a2k=(﹣1)k+1(k+3).从而S 2k =(a 2+a 4)+(a 6+a 8)+…+(a 4k ﹣2+a 4k )=﹣k ,S 2k ﹣1=S 2k ﹣a 4k =k +3. 所以,对任意n ∈N *,n ≥2,B =B =B =B=对于n=1,不等式显然成立.。

For most students, it’s the first time they’re living away from home and managing their own life.Not surprisingly, adapting to this new lifestyle can be challenging. The following four tips will make high school graduates better prepared for college life.Goal settingWhen setting goals, whether theyre academic, career, or personal, re-member they should be attainable but not too easy, so that you really have to push yourself to achieve them, and feel rewarded when you do. Writing down your goals and breaking down each huge, long-term goal into smaller more practical ones can help make it feel more real, and writing out a plan for achieving it can give you a roadmap to success.Interpersonal skillsAt college, you will interact with fellow students, professors, librarians, and many others. Strong interpersonal skills will help you build relationships during this time, and get more out of them. If you feel that your interpersonal skills need some work, practice asking thoughtful questions and listening closely, develop your understandingby putting yourself in someone elses shoes, and enhance yourself-confidence.StudyingWith fewer in-class hours and more on-your-own learning, yourere-quired to really digest learning material rather than simply memorize facts. To be successful in college you’ll need to learn how to integrate large amounts of information obtained through reading, do research, and write pa-pers. Organization is the key, so if you are not someone who is naturally organized, set up your study schedule.BudgetingManaging money is a critical life skill, and for many, it is at college hat they develop it for the first time. Start by estimating your financial ballince. Then give high priority to the expenses on basic needs and determine low much money to set aside every month to cover those costs. Dont forget about savings…and the fun stuff(movies, dinners out), too.36. Who is this passage most probably written for?A. College teachers.B. Universily graduates.C. High school teachers.D. Would-be college students.37. What is the authors suggestion for reaching a huge goal?A. Divide it into smaller, more achievable ones.B. Reward oneself for each goal one has set.C. Purchase a clear, updated roadmap.D. Push oneself to an upper level.38. One of the suggested ways to enhance your interpersonal skills is to .A. prepare complicated questionsB. try on someone elses shoesC. listen to others carefullyD. take advantage of others39. What is the key to successful college study according to the author?A. Being well-organized.B. Being well-informed.C. Effective reading skills.D. Reliable research methods.40. To learn how to manage money, the first thing to do is .A. save money for financial investmentB. estimate ones income and expensesC. set aside money for fun activitiesD. open a personal bank accountBIm an 18-year-old pre-medical student, tall nd good-looking, with two short story books and quite a number of essays my credit. Why am I singing such praises of myself? Just to explain that he attainment of self-pride comes from a great deal of self-love, and to attain it, one must first learn to accept oneself as one is. That was where my struggle began.Born and raised in Africa,I had always taken my African origin as burden. My self-dislike was further fueled when my family had to relocate to Norway, where I attended a high school. Compared to all the white girls around me, with their golden hair and delicate lips, I ,a black girl, had curly hair and full, red lips. My nose often had a thin sheet of sweat on it, whatever the weather was. I just wanted to bury myself in my shell crying “I’m so different!”What also contributed to my self-dislike was my occasional stuttering (口吃), which had weakened my self-confidence. It always stood between me and any fine opportunity. Id taken it as an excuse to avoid any public speaking sessions, and unknowingly let it rule over me.Fortunately, as I grew older, there came a turning point. One day a white girl caught my eye on the school bus when she suddenly turned back. To my astonishment, she had a thin sheet of sweat on her nose too, and it was in November! “Wow,” I whispered to myself, “this isnt a genetic(遗传的) disorder after all. Its perfectly normal.” Days later, my life took an-other twist(转折). Searching the internet for stuttering cures, I accidentally learned that such famous people as Isaac Newton and Winston Churchill also stuttered. I was greatly relieved and then an idea suddenlyhit me—if Im smart, I shouldnt allow my stuttering to stand between me and my success.Another boost to my self-confidence came days later as I was watching the news about Oprah Winfrey, the famous talkshow host and writer—shes black too! Whenever I think of her story and my former dislike of my color, Im practically filled with shame.Today, Ive grown to accept what I am with pride; it simply gives me feeling of uniqueness. The idea of self-love has taken on a whole new meaning for me: theres always something fantastic about us, and what w need to do is learn to appreciate it.41. What affected the authors adjustment to her school life in Norway!A Her appearanceB. Social discrim?nation.C. Her changing emotions.D. The climate in Norway.42. What did the authors occasional stuttering bring about according on Paragraph 3?A. Her lack of self-confidence.B. Her loss of interest in school.C. Her unwillingness to greet her classmates.D. Her desire for chances to improve herself.43. How did the author feel on noticing the similarity between her and ne girl on the bus?A. Blessed and proud.B. Confused and afraid.C. Amazed and relieved.D. Shocked and ashamed.44. What lesson did the author learn from the cases of Newton and Churchill?A. Great minds speak alike.B. Stuttering is no barrier to success.C. Wisdom counts more than hard work.D. Famous people cant live with their weaknesses.45. What can best summarize the message contained in the passage?A. Pride comes before a fall.B. Where there is a will, there is a way.C. Self-acceptance is based on the love for oneself.D. Self-love is key to the attainment of self-pride.CIs it true that our brain alone is responsible fo human cognition(认知)? What about our body? Is it possible for thought and behavior tooriginate from somewhere other than our brain? Psychologists who study Embodied Cognition(EC) ask similar questions. The E(theory suggests our body is also responsible for thinking or problem-solving. More precisely, the mind shapes the body and the body shapes the mind in equal measure.If you think about it for a moment, it makes total sense. When you smell something good or hear amusing sounds, certain emotions are awakened. Think about how newborns use their senses to understand the world around them. They dont have emotions so much as needs—they dont feel sad, theyre just hungry and need food. Even unborn babies can feel their mothers’heartbeats and this has a calming effect. In the real world,they cry when theyre cold and then get hugged. That way, they start to as-sociate being warm with being loved.Understandably, theorists have been arguing for years and stilldis-agree on whether the brain is the nerve centre that operates the rest of the body. Older Western philosophers and mainstream language researchers believe this is fact, while EC theorises that the brain and body are working together as an organic supercomputer, processing everything and forming your reactions.Further studies have backed up the mind-body interaction. In one ex-periment, test subjects(实验对象) were asked to judge people after being handed a hot or a cold drink.They all made warm evaluations when their fingertips perceived warmth rather than coolness. And it works the other way too;in another study, subjects’ fingertip temperatures were measured after being included in or “rejected” from a group task. Those who were included felt physically warmer.For further proof, we can look at the metaphors(比喻说法) that we use without even thinking. A kind and sympathetic person is frequently referred to as one with a soft heart and someone who is very strong and calm in difficult situations is often described as solid as a rock. And this kind of metaphorical use is common across languages.Now that you have the knowledge of mind-body interaction, why not use it? If youre having a bad day,a warm cup of tea will give you a flash of pleasure. If you know youre physically cold, warm up before making any interpersonal decisions.46. According to the author, the significance of the EC theory lies in .A. facilitating our understanding of the origin of psychologyB. revealing the major role of the mind in human cognitionC. offering a clearer picture of the shape of human brainD. bringing us closer to the truth in human cognition47. Where does the new borns’ understanding of their surroundings start from?A. Their personal looks.B. Their mental needs.C. Their inner emotions.D. Their physical feelings.48. The experiments mentioned in Paragraph 4 further prove .A. environment impacts how we judge othersB. how body temperature is related to healthC. the mind and the body influence each otherD. how humans interact with their surroundings49. What does the author intend to prove by citing the metaphors in Paragraph 5?A. Human speech is alive with metaphors.B. Human senses have effects on thinking.C. Human language is shaped by visual images.D. Human emotions are often compared to natural materials.50. What is the authors purpose in writing the last paragraph?A. To share with the reader ways to release their emotions.B. To guide the reader onto the path to career success.C. To encourage the reader to put EC into practice.D. To deepen the readers understanding of EC.DRalph Emerson once said that the purpose of life is not to be happy, but to be useful, to be loving, to make some difference in he world. While we appreciate such words of wisdom, we rarely try to follow them in our lives.Most people prefer to live a good life themselves, ignoring their responsibilities for the world. This narrow perception of a good life may provide short-term benefits, but is sure to lead to long-term harm and suffering. A good life based on comfort and luxury may eventually lead to more pain be-cause we spoil our health and even our character, principles, ideals, and relationships.What then, is the secret of a good life? A good life is a process, not a state of being : a direction, not a destination. We have to earn a good life by first serving others without any expectation in return because their happiness is the very source of our own happiness. More importantly, we must know ourselves inside out. Only when we examine ourselves deeply can we discover our abilities and recognize our limitations, and then work accordingly to create a better world.The first requirement for a good life is having a loving heart. When we do certain right things merely as a duty, we find our job so tiresome that we’ll soon burn out. However, when we do that same job out of love, we not only enjoy what we do, but also do it with an effortless feeling.However, love alone is insufficient to lead a good life. Love sometimes blinds us to the reality. Consequently, our good intentions may not lead to good results. To achieve desired outcome, those who want to do good to others also need to equip themselves with accurate world knowledge. False knowledge is more dangerous than ignorance. If love is the engine of a car knowledge is the steering wheel(方向盘). If the engine lacks power, th car cant move; if the driver loses control of the steering, a road accident probably occurs. Only with love in heart and the right knowledge in mind can we lead a good life.With love and knowledge, we go all out to create a better world by doing good to others. When we see the impact of our good work on the world we give meaning to our life and earn lasting joy and happiness.51. What effect does the narrow perception of a good life have on us?A. Making us simple-mindedB. Making us snort-signted.C. Leading us onto a busy road.D. Keeping us from comfort and luxury.52. According to the author, how can one gain true happiness?A. Through maintaining good health.B. By going through pain and suffering.C. By recognizing ones abilities and limitations.D. Through offering help much needed by others.53. According to Paragraph 4, doing certain right things with a loving heart makes one .A. less selfishB. less annoyingC. more motivatedD. more responsible54. In what case may good intentions fail to lead to desired results?A. When we have wrong knowledge of the world.B. When our love for the world is insufficient.C. When we are insensitive to dangers in life.D. When we stay blind to the reality.55. According to Paragraph 5, life can be made truly good when .A. inspired by love and guided by knowledgeB. directed by love and pushed by knowledgeC. purified by love and enriched by knowledgeD. promoted by love and defined by knowledge四、阅读表达It was a dark and stormy night. The ferocious wind shook the windows wildly, as though someone outside were beating on the glass. It was also New Years Eve. We were having our annual party and had a house full of people just starting to celebrate.Suddenly, we heard loud explosions. Looking outside and up into the hills, we saw sparks(火花) flying from electrical transformers(变压器).One area after another went dark up in those hills. Then there was the loudest explosion of them all and our house went dark too. I tried to find every candle we had and lit them. The candles made everything look lovely. But we had problems. We had fifteen people standing around and we still had to cook dinner. How would we do that without electricity?The barbecue! Why not cook on the barbecue? We men went outside, some holding flashlights and others cooking. We did a wonderful job. The women stayed inside and got the salads ready. Everything was delicious. There were still a few hours to go before the beginning of the new year, so we all sat around the dining room table and sang up until a few minutes be-fore midnight. We couldnt watch the ball drop in Times Square on television but that wouldnt stop us from celebrating. I stood on a chair and, with the help of someones watch to tell us the time, we all counted down andI dropped a tennis ball! We all screamed Happy New Year. We didn’t need electricity for that!Nowadays, we still get together with the same group to celebrate the New Year and we still talk about that special night.I dont think we have ever laughed so much as we did on that New Year’s Eve.56. What does the underlined word mean in Paragraph 1? (1 word)57. What made dinner preparation difficult according to Paragraph 2? (no more than 6 words)58. How did the people celebrate on New Years Eve according to the passage? (no more than 10 words)59. How does the author feel about that particular New Year’s Eve? (no more than 8 words)60. What do you think is the most necessary quality when dealing with an unexpected difficult situation?Please explain why. (no more than 25words)五、写作61.假设你是晨光中学英语口语社的成员李津。
