第十九讲细节理解题(1)(8 min.)(原创)There are hundreds of travel writers. It will not be easy for you to make a mark, unless you are different. Reading the works of great travel writers and getting inspired by them are not a bad thing, but you should not copy their style and their approach. The world needs something new. Greatness is not achieved through following, it is achieved through leading, and to lead you need to choose your own approach!Being a travel writer can be _exacting. You must realize that you will not be the first one in a long line. Flights will not arrive on time for you, every hotel will not have a room for you, and you may not be able to make a living out of your work. So, you should be prepared mentally and physically before you begin your quest to explore the world.When you write a travel guide, you should remember that you are not the subject in your guide! You should always focus on the place that you are exploring. What is the difference between visiting a place and exploring it? The answer is very simple, when you visit a place you ask the question ‘where to go？’ and when you explore, you ask ‘why to go there？’ Your work should not turn out to be just a map which shows directions. It should explain why you chose a specific direction. If you are not curious while traveling, you will never have something new for your readers.I believe that every individual has a unique style of writing. You should dare to have a different approach. Avoid long personal stories and do not neglect grammar and punctuations.You should also take efforts to promote your work. You should make use of blogs, and popular social networking sites to promote your work. Try to establish contact with major publications. Once your work gets published in a big magazine, there is no stopping.There are many travel writers who say that this is the best job in the world. If you love traveling, you will love this job!1. According to the first paragraph, what do you need to do if you want to be a good travel writer?A. Develop your own style.B. Try to imitate others' approach.C. Read a lot of others' works.D. Get instructed by other writers.2. The underlined word “exacting” can be best replaced by “______”．A. interestingB. excitingC. rewardingD. challenging3. When you travel everywhere, what should you keep in mind according to Para.3?A. Patience.B. Curiosity.C. Judgment.D. Excitement.4. We can infer from the fourth paragraph that ______.A. places visited by thousands of writers have no untold storiesB. no one really has the time to read books with hundreds of pagesC. your reputation will be the same even with grammatical mistakesD. you can expect any miracles right after your first work is published5. What is Paragraph 5 mainly about?A. Making a good preparation.B. Visiting and exploring.C. Marketing yourself.D. Remembering some writing tips.(2)(8 min.)(2012·长郡中学月考五)Increasingly over the last few years, we have become familiar with the range of small electronic devices or “smart” accessories (附件，饰品). Pocket heart­rate monitors for joggers and electronic maps are just the first examples of many new products that promise to change our lives in all sorts of surprising ways.As a scientist at New York University, Rosalind Picard tries out different smart accessories before they go on the market. One of these was the so­called “frown (皱眉) headband”. Rosalind was shocked to realize just how often she frowned. Stuck in a traffic jam recently, Rosalind kept hearing the sounds of the tiny sensor inside the band worn around her forehead —each time she frowned in annoyance, the sensor gave out a signal.Another computer scientist, Steven Feiner, is working on a pair of glasses that will do more than help you to see. Imagine you want to try a restaurant in a foreign city but you're not familiar with the dishes on the menu. If you are wearing a pair of Steven's glasses, all you have to do is glance above the restaurant's doorway and your glasses will immediately become windows to the Internet, offering you full details of the meals served inside. The glasses could also be used to help people make speeches, give chefs access to the latest recipes and even provide doctors with patient information while they carry out operations.At the moment, Steven's invention looks more like a large ski mask than a pair of glasses.It's a headset connected to a hand­held computer and a Global Positioning System (GPS) receiver, which tracks the wearer's position. But he says that these head­worn displays will eventually get smaller and lighter as technology improves.And, of course, this new technology has a fashionable as well as a useful application. A chemical engineer named Robert Langer has invented a new microchip that, if put inside a ring, can give off different smells according to a person's mood. That, of course, may or may not appeal to you. And, in the end, it is shoppers, not scientists, who will determine which of these smart accessories will succeed as fashionable items and which are sure to join history's long list of crazy inventions.It is clear, however, that as computers get smaller and cheaper, they will pop up in all sorts of easily­wearable accessories, even in the buttons on your coat. What's more, this is something that's going to happen a lot sooner than we all expect.1. When Rosalind wore the headband, she was surprised at ______.A. how well the sensor workedB. how she was affected by trafficC. how strong the signal wasD. how comfortable it was2. For people eating out, Steven's glasses can ______.A. give them a restaurant's locationB. let them see a restaurant's environmentC. inform them about a restaurant's menuD. tell them about a restaurant's quality3. What is the current problem with Steven's glasses?A. Limited function.B. Inconvenience.C. High cost.D. Poor Internet access.4. In general, what does the writer think about smart accessories?A. They will soon be widely available.B. Much more research is needed into them.C. Only a few of them will appeal to shoppers.D. Most of them are considered to be crazy inventions.5. What's the writer's purpose in writing this passage?A. To advertise some smart accessories.B. To tell interesting stories about smart accessories.C. To argue that smart accessories are fashionable.D. To introduce the ideas of smart accessories.(3)(8 min.)(原创)From the car park at the foot of the Range of the Awful Hand, it is a short walk to what may be the darkest place in Scotland. The site is famous among a small group of enthusiasts who come here in black nights to stand, watch and wonder.The patch of ground is surrounded by 300 square miles of moorland(沼泽地), woods and lakes that form the rough wilderness of Galloway Forest Park in southern Scotland, and in a few weeks, officials at the park will take steps towards making it Europe's first dark sky park.Only two other parks in the world, one in Pennsylvania, the other in Utah, have been recognized by the International Dark­Sky Association, a US­based organization that seeks to preserve the darkest corners of the Earth. To earn dark sky park status, officials will submit digital photographs of the night sky taken through a fisheye lens(超广角镜头). Their application must also be supported by readings from light meters at different points in the park.In 1989, the British Astronomical Society set up a group called the Campaign for Dark Skies to highlight the growing issue of light pollution. W ith increasing urbanization come better­lit streets, roads and buildings, which send light needlessly up into the sky, hiding all but the brightest stars. According to some estimates, the amount of light sent into space costs around $110 million a year.“I f you go out in an urban street and look up at night, you might see 50, maybe 100 stars at best. But come to our park and when you look up, there are so many stars you can't count them. You can see shooting stars, satellites and the Milky Way, with its billions of stars. You don't even need a high­powered telescope: a pair of binoculars is brilliant，” said Keith Muir, an official at Galloway Forest Park.Steven Owens, a British astronomer, also said, “We've become a very urban population, and in doing so we've cut ourselves off from experiences people have had for hundreds and thousands of years.”“People have been looking up at the night sky, telling stories and passing on myths and legends for the whole recorded human history. But when we moved into cities, we lost that deepconnection with the universe. In setting up dark sky parks, we're trying to reconnect people with nature.”1. What attracts people most in Galloway Forest Park?A. The dark nights.B. The wonderful scenery.C. 300 square miles of moorland.D. The rough wilderness.2. What must be included for Galloway Forest Park to gain dark sky status?A. Some myths and legends.B. Some pictures of the Milky Way.C. Digital photographs of the night sky.D. Light meters used at different points in the park.3. Why was the Campaign for Dark Skies set up?A. To highlight the growing issue of light pollution.B. To preserve the wildlife in Scotland.C. To attract world's attention to the dark corners on earth.D. To prevent urbanization.4. In comparison with urban nights, people can ______ at Galloway nights.A. enjoy all the rough wildernessB. breathe fresh airC. enjoy countless starsD. count all the stars 5. What can be the best title for the passage?A. Observing StarsB. Europe's First Dark Sky ParkC. The International Dark­Sky AssociationD. Three Dark Sky Parks in the World(4)(8 min.)Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline­powered cousins.People in California love to tal k about “zero­emissions vehicles”， but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something — usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal(地热的) plants as well, but by far we get electricity mainly by burning something.In other word s, those “zero­emissions” cars are likely coal­burning cars. It's just because the coal is burned somewhere else that it looks clean. It is not. It's as if the California Greensare covering their eyes —“If I can't see it, it's not happening.” Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat — at the generator, through the transmission lines, etc.A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far —so electric cars burn more fuel than gas­powered ones. If our electricity came mostly from nukes(核能发电厂), or geothermal, or hydro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.1. What does “clueless” mean in paragraph 2?A. People are seeing the California Greens everywhere.B. People in California love to talk about “zero­emissions vehicles”．C. People in California love to have their roofs covered with solar cells.D. People there have no idea that so far electricity mainly comes from burning coal, oil, etc.2. What is the main idea of the passage?A. Electric cars are not clean at all.B. Electric cars are better than gasoline­powered ones.C. People cast doubts on electric cars' batteries.D. Gasoline is an efficient way to power a vehicle.3. The electricity we get from a gallon of gas may make our car run ______.A. not less than 25 milesB. more than 25 milesC. no more than 25 milesD. not more than 25 miles4. According to the passage, electric cars ______.A. do not burn fuel and more environmentally­friendlyB. are toxic because it is difficult for nature to clean it up when their batteries are buried in one spotC. are very good at cleaning up when things are not too concentratedD. are poisonous for a long time and will eventually end up in a landfill5. It can be inferred from the passage that ______.A. being green is good and should be encouraged in communicationB. electric cars are not clean in that we get electricity mainly by burning somethingC. zero­emissions vehicles should be chosen to protect our environmentD. electric cars are now the dominant vehicle compared with g asoline­powered cousins答案第十九讲细节理解题(1)怎样成为一个优秀的旅游作家？作者给出了自己的建议。

第二十二讲推理判断题(1)(8 min.)(2012·师大附中一模)Back in the old days, when I was a child, we sat around the family round table at dinner time and exchanged our daily experiences. It wasn't very organized, but everyone was recognized and all the news that had to be told was told by each family member.We listened to each other and the interest was not put­on; it was real. Our family was a unit and we supported each other, and nurtured each other, and liked each other, and — we were even willing to admit — we loved each other.Today, the family round table has moved to the local fast­food restaurant and talk is not easy, much less encouraged.Grandma, who used to live upstairs, is now the voice on long distance, and the working parent is far too beaten down each day to spend evening relaxation time listening to the sandbox experience of an eager four­year­old.So family conversation is as extinct as my old toys and parental questions such as “What have you been doing, Bobby？” have been replaced by “I'm busy, go to watch television.”And watch TV they do; count them by the millions.But it's usually not children's television that children watch. Saturday morning, the children's hour, amounts to only about 8 percent of their weekly viewing.Where are they to be found? Watching adult television, of course, from the Match Game in the morning, to the afternoon at General Hospital, from the muggings and battles on the evening news right through the family hour and past into Starsky and Hutch. That's where you find our kids, over five million of them, at 10 p. m．， not fewer than a million until after midnight! All of this is done with parental permission.Television, used well, can provide enriching experiences for our young people, but we must use it with some sense. When the carpet is clean, we turn off the vacuum cleaner. When the dishes are clean, the dishwasher turns itself off.Not so the television, which is on from the sun in the morning to the moon at night and beyond!Parents must exercise some control and show some concern about the cultural influence on the child when a program not intended for that child is viewed. Parents need to intervene. Nonintervention may be a wise policy in international affairs, but the results of parental nonintervention will not be wise at all.1. From the first two paragraphs one may infer that the writer's a attitude towards “the old days” is ______.A. preferringB. hatingC. being tired ofD. disappointing2. The working parent is not willing to listen to her (his) four­year­old chil d talking about his sandbox games because she (he) is ______.A. boringB. very tiredC. busyD. angry3. According to the writer, the responsibility for the kid's watching adult television and watching it for a long time should be undertaken by ______.A. the television stationsB. the societyC. TV programsD. their parents4. If we use television with some ______， television can provide our young people with much knowledge.A. instruction of expertsB. judgment of our ownC. direction of engineersD. indication of teachers5. What is the main idea of the last paragraph?A. Parental nonintervention will not be praised.B. Nonintervention may be a good policy in international affairs.C. Parents must exercise some control and show some concern about the cultural influence on the children.D. Parents need to intervene.(2)(8 min.)(2012·师大附中二模)Dallas Children's Theater AcademyShow Biz Summer 2012Rosewood Center for Family Arts5938 Skillman*Dallas, TX 75231 * (214) 978­0110Important Information* All classes are taught by DCT Theater Professionals!* All Grade Levels indicated are for Fall 2012.* Tuition Deposit required for registration.* Tuition balance due on the first day of class.

The service is free, and you may get your money back.How is money damaged? Sometimes it is damaged in a fire. Then a person may have mostly ashes to send in. Sometimes money is damaged in a flood. Then the bills are faded and stuck together. People had sent money that had gone through the washing machine. Some bills have been chewed by animals. Others somehow got into blenders.Also some people don't like banks, so they hid their money in unusual places. If bills are buried in cans, they sometimes get moldy. Mice often nibble at money hidden in attics and basements.Once, a truck carrying money for a bank exploded. There was a big fire. The truck company sent in the remains of the bills.

第二十六讲阅读简答(二)(1)(10 min.)(师大附中2012届高三下学期模拟)He seems an unlikely hero, especially one that would save a kid from the jaws of a wild cougar(美洲豹) .Shen Huigang is just now getting recognition for his bravery in fighting off a cougar on Vancouver Island, Canada, during a family outing on Aug. 30.Shen, also known as Ian, was then an exchange student at Kwantlen Polytechnic University enjoying the afternoon on a beach near Ucluelet, a small town on the edge of the Pacific Ocean.With him was a friend, Myles Hagar, and Hagar's two grandchildren.Silently and suddenly a cougar appeared out of nowhere.By the time the two adults spotted the cat, believed to be young but still weighing 30 to 35 kilograms, it already had the head of 18­month­old Julien in its mout h.Instinctively, the young man gestured as if he were ready for a fight, and tried to scare the beast off with the bag in his hands.On hearing the noise Shen made, the animal dropped the kid and Hagar grabbed his grandson from the cougar's jaws. Shen and Hagar gradually chased the animal back into the woods.“We also moved slowly to our vehicle, as we waved our fists and bags, pretending we wanted to fight with it, ”Shen said.“The vehicle wasn't far away but it felt like it took us a century to travel the short journey.”“Any hesitation, at any moment, even a second delay, would have resulted in certain death for Julien. The cougar was just about to break his neck and carry him away to be eaten in the forest.”Hagar said. Julien has since made a full recove ry.Parks Canada spokeswoman Arlene Armstrong told the National Post newspaper of Canada in an interview in August.“The two men acted properly by maintaining eye contact with the big cat and aggressively scaring it off.”1.

Many people were burned to death, but Bentley's case was very different from others' because he didn't die in a house fire. Dr. Bentley was a victim of spontaneous human combustion (人体自燃)．Dr. Bentley was last seen alive on December 4th, 1966. Some friends had been visiting him and they didn't leave his home until about 9 o'clock in the evening. The following morning a meter reader named Don Gosnell arrived at Bentley's home and let himself in. Gosnell headed straight for the basement where the meter(计量表) was kept. While he was down in the basement, Gosnell became aware of some strange smell and he also noticed the presence of some light blue smoke. Naturally, the meter reader(抄表员) was curious about this and he went upstairs.Gosnell found more smoke in the bedroom and an inspection of the bathroom revealed Bentley's fate. All that remained of him was the lower half of his right leg. Bentley's foot was still inside his slipper. The rest of Bentley's body had been reduced to ashes, some of which were on the floor of the bathroom, while the rest of them were down in the basement because the heat from the blazing body had burned a hole in the floor.At the time it was thought that Dr. Bentley might have set himself on fire with his pipe. This theory was dismissed soon because the Bentley's pipe was found on its stand beside his bed in the next room.Nobody has ever been able to offer a satisfactory explanation for what happened to Dr. Bentley. He was just one of many victims throughout the years, whose death is a mystery and may always be so.1. Why did Don Gosnell come to Dr. Bentley's home that morning?

But reports that a newspaper secretly listened to telephone messages of murdered schoolgirls and other private citizens have produced shock and anger.On Friday, British police arrested Andy Coulson, former editor of Britain's best­selling newspaper, News of the World. The investigation led him to resign in January as communications director to Prime Minister David Cameron.The arrest came in a widening investigation of telephone hacking(窃听). Other accusations include paying police for information on stories.The company News International stopped publishing the weekly News of the World. News International belongs to Rupert Murdoch's News Corporation, also known as News Corp. The 168­year­old newspaper published for the last time on Sunday.Police say the victims also include parents of soldiers killed in Iraq and Afghanistan.Prime Minister Cameron called the hacking reports “disgusting”. But he himself is facing attention for having asked Andy Coulson to serve as his media adviser. Mr. Coulson resigned from News of the World in 2007. He left when a reporter was jailed for listening to the phone messages of Britain's royal family members. The prime minister says Mr. Coulson told him he had no knowledge of the phone hacking incidents. He says he wanted to give Mr. Coulson a “second chance”.Rupert Murdoch was born in Australia. He became a citizen of the United States in 1985 so he could buy American television stations. His father, Keith Murdoch, was a famous World War Ⅰ reporter who later led an Australian newspaper group. After his father died, the younger Murdoch took control of the two newspapers that his father owned.Today, he is a media “colossus(巨头)”.

Adults frequently told me that carrots would improve my eyesight, so that seemed like a good reason to try liking them.There was one person who didn't tell me this; he actually told me the opposite. My grandfather overheard somebody tell me that carrots would improve my eyesight. He didn't say anything immediately, but he let me in on a little secret after that person left the room — it was all a big lie. Carrots do not improve your eyesight.Sure, carrots contain beta­carotene, which metabolizes into Vitamin A and everyone agrees that is essential for maintaining eye health, but it does not improve it (unless the body is deprived of it to begin with). Also, it really has nothing to do with carrots, the necessary vitamins can come from any source.So where did this myth come from?During World War Ⅱ， the British were particularly good at shooting down Nazi bombers at night, when it's almost impossible to see other planes. It was as if they had super­human sight, and they did. They had radar.Once news stories started to circulate about these pilots with seemingly super­human eyes, the government needed a good explanation to prevent the Germans from learning about thistechnology: Carrots.Flight Lieutenant John Cunningham, nicknamed “Cats Eyes” for his incredible ability to shoot down enemy planes, had a natural love for carrots. The story wrote itself and they explained that they were feeding other pilots a lot of carrots to improve their eyesight too.1.

2013年普通高等学校招生全国统一考试（新课标Ⅱ）理科综合能力测试（生物部分）一、选择题：每小题6分，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．关于DNA和RNA的叙述，正确的是A．DNA有氢键，RNA没有氢键 B．一种病毒同时含有DNA和RNAC．原核细胞中既有DNA，也有RNA D．叶绿体、线粒体和核糖体都含有DNA参考答案：C【命题立意】：主要考查DNA和RNA的分布以及空间结构。

【解题思路】：在tRNA中，也存在碱基之间的互补配对，故也有氢键，A错；一种病毒中只能含有一种核酸，要么是DNA要么是RNA，B错；核糖体是由核糖体蛋白质和核糖体RNA组成，不含有DNA，D错。

所以答案选择C。

2.关于叶绿素的叙述，错误的是A．叶绿素a和叶绿素b都含有镁元素B．被叶绿素吸收的光可用于光合作用C．叶绿素a和叶绿素b在红光区的吸收峰值不同D．植物呈现绿色是由于叶绿素能有效地吸收绿光参考答案：D【命题立意】：主要考查叶绿素的元素组成和功能。

【解题思路】：植物在进行光合作用时主要吸收的红光和蓝紫光，由于绿色植物几乎不吸收绿色光，所以植物的叶片一般呈现绿色。

3.下列与微生物呼吸有关的叙述，错误的是A．肺炎双球菌无线粒体，但能进行有氧呼吸B．与细菌呼吸有关的酶由拟核中的基因编码C．破伤风芽孢杆菌适宜生活在有氧的环境中D．有氧和无氧时，酵母菌呼吸作用产物不同参考答案：C【命题立意】：考查与典型微生物代谢相关的知识点，具有一定的综合性。

【解题思路】：破伤风芽孢杆菌的代谢类型是异养厌氧型，在有氧的环境中，破伤风芽孢杆菌的代谢要受到抑制，C错。

4．关于免疫细胞的叙述，错误的是A．淋巴细胞包括B细胞、T细胞和吞噬细胞B．血液和淋巴液中都含有T细胞和B细胞C．吞噬细胞和B细胞都属于免疫细胞D．浆细胞通过胞吐作用分泌抗体参考答案：A【命题立意】：考查对免疫细胞和淋巴细胞之间内在联系的理解。

【解题思路】：免疫细胞中包括淋巴细胞、巨噬细胞、树突状细胞等；根据淋巴细胞生成的场所，淋巴细胞又可以分为B淋巴细胞和T淋巴细胞，所以A错。

配套试卷综合测试卷(一)1．D支原体无细胞壁；该人造细胞为原核生物，其增殖方式为二分裂；由于该人造细胞的遗传物质来自人工合成的蕈状支原体的DNA，其代谢方式与山羊支原体不同。

2．B水和无机盐是植物生命活动所必需的物质；生态系统的生物部分包括生产者、消费者和分解者，因此作物、杂草、害虫和细菌等分解者共同组成了农田生态系统的生物部分；灭虫可使农作物的能量尽可能流向对人类有利的方向，即调整能量流动的方向；杂草与农作物形成了竞争关系，锄草可减轻种间竞争，利于作物生长。

3．B“分子马达”是一种蛋白质，其合成需要经过转录和翻译过程；其基本组成单位是氨基酸；每个氨基酸分子中至少都有一个氨基，R基中也可能含有氨基，故一个氨基酸分子中有可能含有多个氨基；细胞内的直接能源物质是A TP，故“分子马达”的运动消耗的能量由ATP提供；RNA聚合酶是以DNA的一条链为模板合成新的RNA分子的，故RNA聚合酶是沿DNA模板移动的“分子马达”，B项错。

4．D森林生态系统的抵抗力稳定性比较强，恢复力稳定性比较弱，火灾过后的恢复过程将是一个非常缓慢的过程；本次大火过后，将使某些生物失去栖息地，从而影响当地的生物多样性。

5．A合成并分泌与该病毒特异性结合的抗体的细胞是浆细胞；抗体与该肠道病毒特异性结合形成抗原－抗体复合物，并被吞噬细胞清除；记忆细胞不会产生抗体，在相应的抗原再次侵入机体后会迅速增殖分化成浆细胞。

6．C从题图中箭头可知，进化的实质是基因频率的改变(a)，A项错误；b是指突变和选择导致基因频率的改变，B项错误；现代生物进化理论继承了达尔文的进化论的核心观点：自然选择学说，C项正确；生物多样性包含基因多样性、物种多样性和生态系统多样性，故D项错误。

7．Ⅰ.(1)蔗糖溶液浓度和半透膜面积(2)0.5 g/mL(3)蔗糖溶液浓度速率(4)缩短记录的时间间隔(5)结果不会相同；原因是钠离子和氯离子可以通过半透膜Ⅱ.(1)不受细胞内K元素进入活细胞的方式为主动运输，需要有氧呼吸提供能量，缺氧条件下吸收将会受到抑制(2)基本等于解析：本实验主考查了渗透作用，实验命题点主要是自变量，因变量与无关变量的控制。
