My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games. Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them. We always felt better when she was around.One days, as I was getting her food, she chewed up（咬破）one of Dad’s shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was Wrong. When I looked at her and said, “Bad girl. ” She looked down at the ground and then went and hid. I saw a tear in her eyes.Brownie turned out to be more than just our family pet. She went everywhere with us. People would stop and ask if they could pet her. Of course she’d let anyone pet her. She was just the most lovable dog. There were many dines whe n we’d be out walking and a small child would come over and pull on her hair. She never barked（吠）or tried to get away. Funny thing is she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loved everyone.Now many years have passed since Brownie died of old age. I still miss the days when shewas with us.41.What would Brownie do when someone was ill in the family?A.Look at them sadly.B. Keep them company.C. Play games with them.D. Touch them gently.42.We can infer from Paragraph 2 that Brownie .A.would eat anything when hungryB. felt scary for her mistakeC. loved playing hide-and-seekD. disliked the author’s dad43.Why does the author say that Browrnie was more than just a family pet？A.She was treated as a member of the family.B.She played games with anyone she liked.C.She was loved by everybody she met.D.She went everywhere with the family.44.Some people got frightened by Brownie when she .A.smiledB. barkedC. rushed to thhemD. tried to be funny45.Which of the following best describes Brownie？A.Shy.B. Polite.C. Brave.D. Caring.BWhen you’re lying on the white sands of the Mexican Riviera, the stresses（压力）of the world seem a million miles away. Hey, stop! This is no vacation---yon have to finish something!Here lies the problem fat travel writer and food critic（评论家）Edie Jarolim. “I always loved traveling and always liked to eat, but it never occurred to me that I could make money doing both of those things. ” Jarolim said. Now you can read her travel advice everywhere --- in Arts and Antiques, in Brides, or in one of her three books. The Complete Idiot Travel Guide to Mexico’s Beach Resorts.Her job in travel writing began Some eight years ago. After getting a PhD in English in Canada, she took a test for Frommer’s travel guides, passed it, and got t he job. After working at Frommer’s, Jarolim worked for a while at Rough Guides in London, then Fodor’s, where she fell so in love with a description of the Southwest of the U. S. that she moved there.Now as a travel writer, she spends one-third of her year on the road. The rest of the time is spent completing her tasks and writing reviews of restaurants at home in Tucson, Arizona.As adventurous as the job sounds, the hard part is fact --- checking all the information. Sure, it’s great to write about a tourist attraction, but you’d better get the local（当地的）museum hours correct or you could really ruin someone’s vacation.46.Which country does Jarolim have in now？A.Mexico.B. The U.S.C. The U.K.D. Canada.47.What is most difficult for Jarolim？A.Working in different places to collect information.B.Checking all the facts to be written in the guides.C.Finishing her work as soon as possible.D.Passing a test to write travel guides.48.What do we know about Jarolim from the text？A.She is successful in her job.B.She finds her life full of stresses.C.She spends half of her time traveling.D.She is especially interested in museums.49.What would be the best title for the text?A.Adventures in Travel WritingB. Working as a Food CriticC. Travel Guides on the MarketD. Vacationing for a LivingCThousands of people living in the Chinese capital will celebrate the start of the Chinese New year by heading for the ski resorts （滑雪场）. Never mind that Beijing’s dry weather seldom produces snow. It is cold enough in winter for snow --- making machines to make a covering for the hills north to the capital. And the rapid growth of a pleasure --- seeking middle class has formed the basis for this new craze （热潮）.Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed astonishing increase. There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr. Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts in Europe.Beijing’s skiing craze is partly a result of the recent increase in private（私有的）cars. This has led to the growth of a leisure industry in the capital’s suburbs（郊区）, which until the late-1990s were unreachable to ordinary people. According to Mr. Wei, about 40% of the visitors to his resort come in their own cars. The rest are bused in by schools, businesses or government offices.The problem is making money. Starting ski resorts requires quite a lot of money; hiring land from the local government, preparing the hills, buying snow machines, making sure there are enough water and electricity to run them, and buying ski equipment for hiring out to customers.The ski resort where Mr. Wei works cost nearly $4m to set up. And as so often in China when someone comes up with a good idea, many others hash in and price wars break out. Beijing now offers some of the cheapest ski training classes in the world, though with most people rather new to the sport, expecting a few more doing the samejob.50.What does this text mainly talk about？A.Convenience for skiers brought about by private cars.B.Skiing as a new way of enjoying one’s spare time.C.Things to be considered when starting a ski resort.D.A sudden increase of ski training classes in Beijing.51.Why are some Chinese likely to go skiing in Europe？A.To visit more ski areas.B. To ski on natural snow.C. For a large collection of ski suits.D. For better services and equipment.52.The underlined words “leisure industry” in Paragraph 3 refer toA.transport to ski resortsB.production of family carsC.business of providing spare time enjoymentsD part-time work for people living in the suburbs53.What is the main problem in running a ski resort？A.Difficulty in hiring land.B. Lack of business experience.C. Price wars with other ski resorts.D. Shortage of water and electricity.Ariau Amazon TowersDCoolest Hotels in the WorldThe Ariau Amazon Towers hotel lets you sleep in a tree house.

Ariau Amazon Towers.C. The Ice Hotel.D. Bahama Beach Club.EHow words came into being is unknown. All we assume（推测）is that some early men invented certain sounds, in one way or another, to express thoughts and feelings, actions and things, so that they could talk with each other. Later they agreed upon certain signs, called letters, which could be put together to show those sounds, and which could be written down. Those sounds, whether spoken or written in letters, are called words.The power of words, then, lies in their associations---the things they bring up to our minds. Words become filled with meaning for us by experience; and the longer we tire, the more certain words bring back to us the happy and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.Great writers are those who not only have great thoughts but also express these thoughts in words which have powerful effects on our minds and feelings. This clever use of words is what we call literary style （文体）. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech silly and common.58.We learn from the text that language might have begun with .A.expressionsB. actionsC. signsD. sounds59.What is mainly discussed in Paragraph 2?A.The learning of new words.B.The importance of old wordsC.The relation of human experience with words.D.The gradual change and development of words.60.In the last paragraph, what does the author suggest that we should do?e words skillfully.B. Make musical speechesC. Learn poems by heart.D. Associate with listeners.第二节（共5 小题；每小题1 分，满分5 分）根据对话内容，从对话后的选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑，选项中有两项为多余选项。

中国农业机械工业协会副秘书长宁学贵年月，赛迈道依茨法尔公司在山东常林建厂生产拖拉机.至此，约翰迪尔、爱科、凯斯纽荷兰等全球农机巨头以及日韩优秀农机企业几乎全部进入中国并建立制造基地.法国、意大利等农机企业也加大了进入中国市场地工作力度.资料个人收集整理，勿做商业用途据中国农机工业协会统计，到年月底，全国多家农机企业地工业总产值为亿元.其中外资独资、控股农机制造企业有家，（包括港澳台控股企业家），外资企业个数占规模企业数地，外资企业总产值占，外资企业工业销售总产值占.资料个人收集整理，勿做商业用途外资企业地积极作用国外著名农机企业地到来，对我国农业机械化和农机工业地发展起到了积极地推动作用.首先他们带来了先进地技术和新产品.外国企业在中国制造地产品覆盖了发动机、拖拉机、收获机、插秧机、整地机、畜牧机械、设施农业装备和基础部件等，同时还带来了采棉机、甘蔗收获机等国内空白产品，这使得我们实现农业生产全程机械化地进程大大加快.资料个人收集整理，勿做商业用途外资企业为我们带来了先进地商业操作模式和管理经验，有利于国内农机企业地管理者迅速提高现代企业管理水平.我们从跨国公司那里学到了先进地工厂管理方式、供应链地高效管理、品牌建设地内涵和企业社会责任地彰显等.资料个人收集整理，勿做商业用途外资企业在中国制造，促进了全行业地制造能力和产品质量地进步，提升了农机产业链地全面升华.几年前，大多数国产农机产品给人地印象还是“傻、笨、粗”或“破铁皮上刷红漆”，如今，数控加工、激光和等离子切割、电泳表面处理、自动焊接等先进技术已经成为农机制造企业必备地制造手段，农机产品地整体质量得到了很大地提高，尤其是国内农机产品地外观质量与国际品牌地差距在讯速缩小.资料个人收集整理，勿做商业用途外资企业地中国策略外国企业资金雄厚，进入中国投资力度大，起点高.目前，国外农机企业很少再以代理、代办、参股、技术合作地方式进入中国，而多是采取直接投资、收购本土优秀企业建立自己地制造基地，推行其全球经营战略和品牌发展战略.他们在我国地企业多是独自股权投资，利用其全球范围地资源经营管理.他们在中国设立地制造基地非常重视制造能力和硬件地投入，具有强大地产品竞争和市场垄断能力.据称，爱科公司在常州地生产线和厂房全部是按照国际最先进地水平设计和建造，年投产后会成为国际最先进地农机制造基地.资料个人收集整理，勿做商业用途外资农机企业进入中国后能迅速地适应我们地文化和市场，其“本地化”战略对本土企业地杀伤力是巨大地.他们注意培植本土化地供应链和协作能力，产能快速提升.他们充分利用中国较低地劳动力价格降低产品成本，从而在国内农机行业赢得了自己地领先地位.资料个人收集整理，勿做商业用途他们进军中国最为看重地是我们巨大地市场，故经营策略多确定为中国制造，中国销售为主.所以，他们非常注意吸收国内产品地技术特点，中为洋用，很快就取得了好地国内市场份额.比如，国内企业普遍赖以生存地四行玉米机、公斤以下小马力稻麦收割机、水稻插秧机、水稻全喂入收割机、中小马力拖拉机等普通产品，外资企业也凭其品牌效应和良好地制造工艺，赢得了整机美观、质量优异、性能可靠地用户口碑，虽然其以比国产机高出以上地价格销售，还供不应求，显示出强有力地市场竞争优势.我们这些主力产品也在逐渐失去市场.资料个人收集整理，勿做商业用途在高端产品上，外资企业更是表现出绝对地优势.大马力拖拉机、采棉机、半喂入式水稻收割机、宽幅收割机等产品，国外品牌地市场知名度就非常高，国内企业还无法与其竞争.资料个人收集整理，勿做商业用途借农机购机补贴政策地支持，近几年外资企业在华投资收益表现突出，给股东进入中国带来了更大地信心，促使其不断在中国延伸投资，不断扩大其中国地市场份额.资料个人收集整理，勿做商业用途新地格局：“与狼共舞”国外农机企业给我们带来技术进步和产业升级地同时，也给本土农机企业带来了极大地压力和威胁.我们看到国内优秀地企业正被外企不断地吞并，本土企业地行业主导地位正在逐步下降，国内企业地市场份额被不断挤占，本土企业人才流向外企，民族企业地产品利润空间越来越小，中小农机企业地生存越发困难……资料个人收集整理，勿做商业用途再细分我们地产品就会发现，本土农机产品地质量和性能与国外农机产品还存在非常大地差距，国产农机产品地品种也屈指可数，而且企业持续发展地能力非常薄弱.资料个人收集整理，勿做商业用途中国农机工业协会名誉会长高元恩通过对比研究中国和巴西农机工业地发展，认为中国本土地民族农机企业现在已经被逼到了悬崖边缘，对此深感焦虑.资料个人收集整理，勿做商业用途巴西和中国一样也是农业大国，十分重视农业机械化发展，农机市场非常活跃，因此也就成了跨国农机企业青睐、投资、争夺之地.经过十多年地博弈，目前，巴西高端地、大型地、市场占有率高地农机产品全部成了跨国公司地品牌，巴西农机企业只能制造和销售低端地、价廉地产品，并且不断被外企打压，举步维艰.资料个人收集整理，勿做商业用途中国农机工业正面临同样地危机，这绝不是危言耸听.近几年，在国家地支持下，在诸多利好因素地推动下，中国农机工业产值以年均近地比例高速增长、快速发展.但中国农机工业协会公布地年农机工业强地入围门槛仅为亿元，农机企业以上是中小企业.企业规模小又缺乏特点，抗风险能力就比较弱，更谈不上“与狼共舞”了.资料个人收集整理，勿做商业用途。

Choose the one that fits best according to the information given in the passage you have just read.AWhen someone has deeply hurt you, it can be extremely difficult to let go ofyour anger. But forgiveness is possible – and it can be surprisingly helpful to your physical and mental health. Indeed, research has shown that people who forgive report more energy, bett er appetite and better sleep patterns. “People who forgive show less anger and more hopefulness,” says Dr. Frederic Luskin, who wrote the book Forgive for Good “So it can help save on the wear and tear on our system and allow people to feel more energetic.”So when someone has hurt you, calm yourself first. Take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, someone you love. Don’t wait for an apology. “Many times the person who hurt you may never think of apologizing,” says Dr. Luskin. “They may have wanted to hurt you or they just don’t see things the same way. So if you wait for people to apologize, you could be waiting a very long time.” Keep in mind that forgiveness does not necessarily mean accepting the action of the person who upset you. Mentally going over your hurt gives power to the person who brought you pain. Instead, learn to look for the love, beauty and kindness around you. Finally, try to see things from the other person’s perspective(视角). You may realize that he or she was acting out of ignorance, fear – even love. To gain perspective, you may want to write a letter to yourself from that person’s point of view,65. The text is mainly written to explain _______.A. how to keep yourself from being hurtB. how to stay mentally healthyC. how and when to remain calmD. why and how to pardon others66. According to the writer, what is the right way to calm down after being hurt?A. Try to figure out why you get hurt.B. Write a letter to the person who hurt you.C. Persuade yourself to accept what others have done to you.D. Think about pleasant things and forget about the hurt.67. Dr. Luskin advises us not to wait for an apology after being hurt because _______.A. we are not patient enoughB. we’d feel worse accepting others’ apologyC. people never want to apologizeD. people don’t mean it when they apologizeBWe Are Now Open Daily Through Columbus DayThe museum and store are open from 10 a.m. to 5 p.m. throughout the season. Trolley rides start with the first departure at 10:05 a.m. and continue until the endAt 7:30 p.m., every Wednesday and Thursday evening in July and August, join us for a special sunset trolley ride with ice-cream included.

No school I have taught in has ever ignored spelling or considered it unimportant as a basic skill. There are, however, vastly different ideas about how to teach it, or how much priority (优先，重点) it must be given over general language development and writing without holding him back with the complexities of spelling.If spelling becomes the only key point of his teacher’s interest, clearly a bright child will be likely to “play safe”. He will tend to write only words within his spelling range, choosing not to use adventurous language. That’s why teachers often encourage the early use of dictionaries and pay attention to content rather than spelling ability only.I was once shocked to read a teacher’s comment on the bottom of a sensitive piece of writing: “This work is terrible! There are far too many spelling mistakes!” It may have been a sharp criticism of the pupil’s spelling ability in writing, but it was also a sad reflection on the teacher who had failed to read the composition which contained some beautiful expressions of the child’s deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priorities had centered on the child’s ideas, an expression of his appreciation would have given the pupil more encouragement to seek improvement.72. The underlined expression “play safe” in paragraph two probably means _______.A. to write carefullyB. to do as teachers sayC. to use dictionaries frequentlyD. not to write words one is not sure of73. Teachers encourage the use of dictionaries so that _______.A. they may spend more time teaching writing techniquesB. they may have less trouble in correcting mistakesC. students will have more confidence in writingD. students will learn to be independent of teachers74. The writer seems to think that the teacher’s judgment on that sensitive piece ofwriting is _______.A. reasonableB. unfairC. foolishD. careless75. Teachers are different in their opinions about _______.A. the necessity of teaching spellingB. the role of spelling in general language developmentC. the way of teaching spellingD. the importance of the basic grammarDA study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities and food experiences. “One week later,” Loftus says, “we told those people we’d fed their answers into our smart computer and it came up with an account of their early childhood experiences.” Some accounts included one key additional detail: “You got sick after eating strawberry ice-cream.” T he researchers then changed this detail into a manufactured (人为促生的) memory through leading questions “Who were you with? How did you feel?” By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they’d avoid eating it.When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it’s not that easy. False memories appear to work only for fo odsyou don’t eat on a regular basis. But most important, it is likely that false memories can be implanted (灌输) only in people who are unaware of the mental control. And lying to a patient is immoral, even if a doctor believes it’s for the patient’s benef it.Loftus says there’s nothing to stop parents from trying it with their overweight children, “I say, wake up. Parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that’s a more moral lie. Decide that for yourself.”76. Why did Loftus ask the volunteers to answer some questions?A. To improve her computer program.B. To find out their attitudes towards food.C. To find out details she can make use of.D. To predict what food they’ll like in the future.77. What did Loftus find out from her research?A. People believe what the computer tells them.B. People can be led to believe in something false.C. People tend to forget their childhood experiences.D. People are not always aware of their personalities.78. According to the study, people may stop having a certain food if they______.A. learn it is harmful for healthB. lie to themselves that they don’t want itC. are willing to let doctors control their mindsD. think they once had a bad experience of eating it79. What is the biggest concern with the method?A. Whether it is moral.B. Who it is best for.C. When it is effective.D. How it should be used.Section CDirections: Read the following text and choose the most suitable heading fromA study of art history might be a good way to learn more about a culture than is possible to learn in general history classes. Most typical history courses concentrate on politics, economics and war. But art history focuses on much more than this because art reflects not only the political values of a people, but alsothe daily activities of our ancestors –or of people very different from our own – can be provided by art. In short, art expresses the essential qualities of a time and a place, and a study of it clearly offers us apresented; that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective: it reflects emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly “political” artist. In his well-known painting The Third of May 1808, he criticized the Spanish government for its misuse of power over people. Over a hundred years later, symbolic images were used in Pablo Picasso’s Guernica to express the horror of war. Meanwhile, on another continent, the powerful paintings of Diego Rivera, Jose Clemente Orozco, and David Alfaro Siqueiros – as well as the works of Alfredo Ramos Martins –’s religious beliefs. For hundreds of years in Europe, religious art was almost the only type of art that existed. Churches and other religious buildings were filled with paintings that depicted people and stories from the Bible. Although most people could n’t read, they could stillstill is) its absence of human and animal images. This reflects the Islamic belief that status are unholy.第II卷I.

2010年普通高等学校招生全国统一考试理科综合能力测试(全国卷Ⅱ)第Ⅰ卷以下数据可供解题时参考：相对原子质量(原子量)：H 1 C 12 N 14 O 16一、选择题(本题共13小题。

在每小题给出的四个选项中，只有一项是符合题目要求的)1．下列关于高尔基体的叙述，错误．．的是()A．高尔基体膜具有流动性B．抗体从合成到分泌不经过高尔基体C．高尔基体膜主要由磷脂和蛋白质构成D．高尔基体具有对蛋白质进行加工的功能答案：1．B高尔基体是具有单层膜的细胞器，膜的结构与细胞膜类似，在结构上具有一定的流动性；高尔基体膜组成上主要由磷脂双分子层和蛋白质构成；高尔基体与细胞分泌物的形成有关，它本身没有合成蛋白质的功能，但可以对蛋白质进行加工和转运；抗体是一种分泌蛋白，从合成到分泌的过程中需经过高尔基体的加工和转运。

2．下列关于免疫细胞的叙述，错误．．的是()A．效应T细胞可以释放淋巴因子B．T淋巴细胞可以产生多种抗体C．吞噬细胞和淋巴细胞均属于免疫细胞D．一个效应B淋巴细胞只能产生一种抗体答案：2．B吞噬细胞和淋巴细胞均属于免疫细胞。

淋巴细胞又分为T细胞和B细胞，受到抗原刺激后，T细胞可增殖分化形成效应T细胞，而效应T细胞既可与靶细胞密切接触，还能释放出免疫活性物质——淋巴因子，但不能产生抗体；B细胞接受抗原刺激后，可增殖分化成效应B细胞，效应B细胞可产生抗体；一个效应B细胞只能产生一种抗体。

3．下列关于生态系统的叙述，错误．．的是()A．草原生态系统比农田生态系统的群落结构复杂B．环境条件分布不均匀是形成群落水平结构的原因之一C．我国南方热带雨林中分解者的代谢活动比北方森林中的弱D．植物可通过呼吸作用和光合作用参与生态系统的碳循环答案：3．C农田生态系统是人工建立的生态系统，人们种植的各种农作物是这一生态系统的主要成员，农田中的动植物种类较少，群落的结构单一，与农田生态系统相比，草原生态系统的动植物种类多，群落结构也复杂；群落在水平方向上具有一定结构的主要原因为地形的起伏、光照的明暗、湿度的大小等，即环境条件分布不均匀；我国南方气温较北方高，南方热带雨林中分解者的代谢活动比北方森林中的强；生态系统的碳循环主要是以二氧化碳的形式进行，大气中的碳进入生物群落需通过植物的光合作用，而植物通过呼吸作用释放的二氧化碳又可重新回归大气。
