杨浦区2012届一模语文试卷及参考答案

上海市杨浦区2012 届高三第一学期期末考试语文试卷(答案做在答题卡上)(满分150 分,时间150 分钟)2011 年12 月一阅读(80 分)(一) 阅读下文,完成1-6 题。

(16 分)(1) 我们知道,人的情绪、心理、性格极易受到周围世界的影响。

(2) 那么,清旷灵秀的江南山水又对人的文化心理产生着怎样的影响呢?(3) 学者常常引用孟德斯鸠的观点来阐述气候对人的精神气质的影响。

孟德斯鸠认为:“人们在寒冷气候下,便有较充沛的精力”,“有较强的自信,也就是说,有较大的勇气。

”相反,如果把一个人放在闷热的地方,由于上述原因,他便会感到心神萎靡,缺乏勇气。

孟德斯鸠的观点虽然有绝对化的倾向,但其独特的视角却给人以启发。

我们可以这样认为:在一般的情况下,寒冷的气候使人勇敢、豪爽,炎热的气候使人敏感、消沉,而长期在湿润的气候条件下生活的人们,则具有和谐、平衡、机敏、细腻的心理特征。

江南文化在其发展过程中,虽然经历着千门万户的变换,但基本的心理图景却由其地理环境所规定。

(4) 再就地形地貌的影响来看,黑格尔曾以地形地貌为依据将地理环境分成三种类型,即高原、平原和海岸区域。

在黑格尔看来,三种不同的地理环境分别形成了牧业、农业和商业等不同的文化形态。

我们在讨论江南文化结构中的精神层——亦即江南文化精神的时候,同样可以通过比较江南江北地形地貌的差异来进行阐述。

(5) 不同的自然风貌会影响到人的审美心理。

我们知道,就普遍的情况来看,北方多崇山峻岭和高原,植被和色彩都显得相对单调。

但另一方面,这单调却又是严峻、崇高和阔大的,生活在那里的人们,目光所及,是巨大而高远的世界,所以,生活在北方的人其心胸也就随之扩展,喜好刚毅雄强、粗犷豪迈的美感类型;而江南则有丰饶的物产、秀美的山川,其植被繁密而多彩,景观变化细微而多端。

生活在这里的人们,长期感受着的是温山软水、莺飞草长,是一川烟草、满城风絮,因此,其文化心理极易被导向精细和柔婉,沈谦评辛弃疾词云:“稼轩词以激扬奋励为工,至‘宝钗分•桃叶渡’一曲,呢狎温柔,魂销意尽,才人伎俩,真不可测。

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Not many people know about the clouded leopard. Even scientists don’t know much about the animal in the wild because it is so private. We do know that the clouded leopard isn’t actually a leopard. It is a species of its own. However, it does have spots like a leopard. They help it blend into the background in the forest.What else do we know about the cat? It is one of the best climbers of all wild cats. This skill is clearly imprinted in the kittens early on by their mothers and by instinct. In the wild, the cat lives in the tropical rain forests of Asia. It hunts small animals, such as squirrels and monkeys. It is listed on the United States Endangered Species Act. This protects it from being hunted. Scientists have speculated that the wild population is getting smaller, but no actual numbers are available.The Clouded Leopard Project works to conserve and protect the population of these cats. The project teaches about clouded leopards, analyzing their habits in captivity by watching their behaviors and interactions. The project realizes it is important to the cats’ survival to breed the animals in zoos. If more clouded leopards aren’t born, the population will be pushed quickly into extinction.The Clouded Leopard Project has recently begun a conservation effort in Thailand. It is a natural home of the clouded leopard. Funds will be given to the Khao Kheow Open Zoo to help with the breeding of these cats. Part of the money also will help save the habitat of the wild cats. People will work to monitor these wild cats. They will be photographed instead of being sedated, or drugged, to be tagged(加标签). Sedating clouded leopards could cause the cats’ bodies to lose too much water, or worse.The project has had some great successes in the last few years. Two cubs were born in the United States, and two were born in Thailand. Members of the Clouded Leopard Project hope the urge to protect such species will become embedded in people’s minds. They sponsor several education programs at zoos. They also sponsor programs to directly help the cats. Through their work they ultimately will increase the population of this species.65. What made a clouded leopard not easy to find in the forest?A. Spots like a leopard.B. A species of its own.C. Best climbing skills.D. Extinction of such animals.66. _____ is not included in the Clouded Leopard Project?A. Breeding clouded leopards in zoos.B. Monitoring the cats by labeling them.C. Starting educational programs at zoos.D. Saving the cat’s natural habitat.67. The underlined word “embedded” means _____.A. focusedB. rootedC. determinedD. talented68. Which of the following statement is TRUE?A. Clouded leopard is a rare kind of leopard with nice spots.B. Lack of food in the wild makes the survival of the cats more difficult.C. The Clouded Leopard Project aims at increasing the population of the cat.D. Observing clouded leopards’ behavior protects the cats from bein g hunted.(B)(C)With greenhouse gas emissions(排放)hitting record levels and passing climate scientist's worst predictions, a new group of Chinese activists is making its voice heard at the United Nations climate talks, the COP17, which was held in Durban, South Africa.The delegation of independent Chinese non-governmental organizations (NGOs) believes that civil society must play a bigger role in the global climate crisis. C Plus is the name given to the project launched by 42 Chinese NGOs,calling for domestic and global action to fight climate change. And they think the best way of demanding governments' action is to take action by themselves. The message is clear: climate action is too important and too urgent. It can't wait. The top-down process of negotiations that we are seeing at the UN is too slow.C Plus has three components, which together explain its name. C Plus stands for: Beyond Commitment. This means that NGOs must put pressure on their governments to achieve targets that are beyond those that have been officially stated. Second is Beyond China -- in other words, NGOs outside and inside of China together must strive to influence their respective governments to take action. Finally, Beyond Climate. The project targets not just carbon reduction but other environmental measures as well such as clean water and air, public education, water conservation and preservation of forests.In the last few years, NGOs have played an active role in influencing the government's policy making, supervising the government's task of environment responsibility and raising public awareness in environment protection.And NGOs can claim some notable successes. NGOs sponsored “26-degree air conditioning office”among the public, which later became a government regulation. A group of Chinese citizens organized together and stopped the construction of a dangerous chemical plant in Xiamen.In total, there are 3,539 environment NGOs in China, in which 55.2 percent now have their own offices, and 26 percent have fixed source of investment. However, most environment NGOs still face problems including difficulty in raising money, shortage in personnel and weak organization ability in their development process.In Durban, Chinese NGOs have arrived as a team and are prepared to state their demands.72. The passage is mainly about _____.A. Durban climate change conferenceB. environment NGOs in ChinaC. C plus project launched by NGOsD. achievements of NGOs73. Which of the following is true about the C Plus?A. It is an organization devoted to controlling the greenhouse gas emission.B. It is a program aiming at influencing government to take action to protect environment.C. It is a project designed by the government to unite NGOs inside and outside China.D. It is a statement calling for public awareness in environment protection.74. Most environment NGOs don’t lack _____.A. financial supportB. human resourcesC. development goalsD. organizational skills75. What can be inferred from the passage about the NGOs?A. They once pushed the government to make a regulation concerning office temperature.B. They pushed forward the slow negotiations by adopting the top-down style.C. They were directly involved in making environment-related policies.D. They successfully pressurized the government to achieve the unofficially stated targets.Section CDirections: Read the following text and choose the most suitable heading from A-F for each paragraph. There is oneA. Possible causes of autismB. Special programs for autistic patientC. Different treatment and IQ, different futureD. What is autismE. Common symptoms of autismF. Language and communication disorder76.feeling a part of the outside world. Taken from the Greek word autos meaning “alone,” autism prevents children from developing normal social relationships, even with their parents.77.Not all autistic infants and children are alike; in fact, there is no single typical clinical picture of the disorder. However, certain types of behavior are noted in a majority of autistic children. Autistic infants will not cuddle, and they do not like to be picked up. The usual things that children do to imitate adults, such as waving goodbye, are not observed in autistic children. Instead, autistic children very often repeat such movements as flicking a hand, twisting an arm or leg, or banging the head over and over. Strange gestures and distorted facial expressions are common.78.they hear or communicate by gestures. They have little or no interest in making friends. They smile rarely, if ever, and will avoid making eye contact. Unlike normal children, they tend to fixate on a single object or task, such as spinning the wheels on a toy car over and over.79.At one time autism was blamed on bad parenting. Now it is believed to be caused by abnormalities in the brain. Several possible causes of these abnormalities have been proposed: an illness the mother suffered during her pregnancy; too little oxygen at the time of birth; or possibly an abnormal gene. In some cases, X rays have revealed abnormalities in the structure of the brain itself. There is no way to diagnose autism apart from observing the child's behavior closely over a period of time.80.programs can help children function better, the life of these children is generally hard to predict. Some will remain severely impaired throughout their lives. A majority always will depend heavily on support from relatives and professional caregivers, and may require special living arrangements and close supervision. However, progressive changes in the treatment of these children have enabled about one in six to live independently and work productively. What’s more, the intelligence level of the child partly affects the ability to function.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.If you have been following the news you will know that the world’s population recently reached seven billion –probably on 31st October.The statistics concerning human population growth are astonishing. It was only 12 years ago, in 1999, that the world’s population reached six billion. In 1969 there were 3.5 billion people on the planet, which is to say our numbers have doubled in only 42 years. A century ago, in 1911, there were only 1.8 bil lion of us: 26% of today’s total.As for future population growth, it seems there will probably be eight billion people by 2030 and nine billion by around 2050. After that, predictions vary: many experts think the total will rise more slowly, perhaps reaching ten billion by the end of the century; but a few believe the fast rise might continue, leading to a global population of as many as 15 billion by 2100.There are big differences between rates of population growth around the world. The fastest rates are generally in theworld’s poorer countries, including those in sub-Saharan Africa, while the populations of rich countries are mostly growing much more slowly, or even shrinking in a few cases. (Germany and Japan, for example, will have smaller populations in 2050 than they do now.) This fact explains another interesting statistic: in 1900 Europe contained around 25% of the world’s people, but in 2050 it will have less than 10%.There are many reasons for fast population growth, but the most significant include medical advances and generally improved standards of living in poor countries, which mean fewer deaths from diseases or from malnutrition. Indeed, average life expectancy across the world has risen 20 years since the 1950s, from 48 to 68, and the biggest rises have been in poor countries.Some people already talk of a crisis of overpopulation, expecting there to be wars over access to natural resources and warning that, because those resources are limited, it is impossible for seven billion people (let alone nine or ten) to have the kind of high-consumption lifestyles that people in the world’s richer countries currently enjoy. Others, however, believe the planet can accommodate another two or three billion humans without a social or environmental disaster.We can only hope the optimists will be proved right.(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS)81. When was the world’s population half of what it is now?82. There seems to be a connection between a count ry’s rates of population and_________________________________________.83. What contributed to the fast population growth?84. Some people predicted that the conflict between _______________________ may lead to wars.第II卷(共45分)I.

But when I was 16, I was the 51 player on the football field.My high school coach (教练)was Ollie Jarvis, who not only believed in me but also taught me how to believe in myself. One incident (事件)with Coach Jarvis changed my life forever.It was during the summer vacation, and there was a chance to get a summer job andearnsome money that I wanted very much. Then I realized I would have to52 summer football camp to earn the money. When I told Coach Jarvis, he was as 53 as I expected him to be. "You have your whole life to work," he said. "Your playing days are 54 You can't afford to waste them."I stood before him with my head hanging. "How much are you going to make from this job?" he asked. "$3.25 an hour," Ireplied. "Well," he asked, "is $3.25 an hour the 55_ of a dream?" That question made me56 the difference between wanting something right now and having a goal. I spent the whole summer training on the football field, and within the year I was 57 by one of the best teams in the state.I finally achieved my goal in life because I followed my dream. The point is that no matter who you are and no matter where you are, you should always have a dream.

There are about 160 books in the cart, but he has got over 1000 books. Most of his books are donated by people who support his work.Two years ago, he used to earn a living by selling water in the street. As he was waiting for the customers, he sat there and read. One day a reporter saw him and offered him some books from his office. That is how the library cart started. People from all walks of life are welcome to pick up a book from his cart and read. He doesn't keep a record of who borrows which book. He trusts (信任) people to return the books after reading them. Every Friday he introduces his cart at a culture event where he talks to the children about the importance of reading and of the books he likes most. He often reads passages of his favorite books there. He hopes more young people can find the magic of reading.With the cart, he wants to encourage the people to form good reading habits. People in Europe read an average of 4 books a month but in Colombia people read an average of 1.5 books a year. To the people in Colombia, books are expensive and few can afford to buy them. Besides, people do everything on computers nowadays and many have forgotten the joy of reading. ,Martin only went to the fifth grade because his family had no money: He often had only one meal a day. He remembered once saying to his mom, "I'm too hungry to study." "Whatever you learn, it is like saving for the future," said his mother.Martin is proud of his work. He thinks that the library cart can prepare children for a better future with knowledge and technology.74. Martin didn't have much education because______ .A) he didn't like to learn B) his family was too poorC) he was too hungry to learn D) he got tired of learning75.

Where can this library cart probably be seen in Columbia?A) On the computer. B) In the school library.C) Inside the office building. D) In the city streets.78 Who are likely to be the audience (听众)at the culture event?A)Newspaper reporters.B)Business peopleC)School children. D)Bookstore owners79 Martin hopes that the library cart can__________ .A) offer books at lower prices B) make him better knownC) enable people to buy more books D) spread the joy of readinghsB) Choose the words or expressions to complete the passage(12分)Ten years later, I can remember my time in seventh grade like yesterday. The thing I remember most about is my English teacher, Mr. Mabry. He was, by far, the best teacher in the world. First of all, he didn't use80 method of teaching. Instead, he used his theater background to make learning English grammar fun for the whole class. When we studied Shakespeare, we 81 acted out the parts, so that we really had a good understanding of Shakespeare's works.He also did many other things for us. He encouraged his students to ask questions about anything and everything and then, he would82 to give us an honest answer. He taught us how to trust one another by playing games with us. He would make one person83 backward while another person stood behind and caught him. As well, he used to let us have parties every week at school. If we wanted to have a party, he would give us our homework for the day of the party and we would do it at home.

On the first morning, Jenny spent hours playing by herself. It seemed that she felt very1 86 .However, to my joy, Jenny's classmates always encouraged, her, ‘you got all your spelling words right today!" In fact her spelling list was thee 87 Lateshefaced a very painfulproblem—at the end of the term, there was a game which had something to do with physical education. But Jenny was waybehind in it:My husband and I were anxious (忧虑)about the day. I wanted to keep her home. Whylet Jenny fail in a gymnasium filled with parents, students and teachers? What a simple s88 ! But my heart wouldn't let me off that easily. So I pushed a pale, unwilling Jenny onto the school bus.At the kindergarten, I was quite worried because of her s 89 action. Jenny would probably hold up (阻碍)her team. The game went on well until it was time for the sack (麻袋)race.Surely Jenny would find it difficult. Now each child had to climb into a sack, jump to the finishing line, return and climb out of the sack. Inoticed Jenny standing near the end of her line of players.But as it was her turn to join, ac90 place in her team. The tallest boy behind Jenny placed his hands on her waist (腰).Two otherboys stood ahead of her. The moment the player before Jenny stepped out from the sack, those two boys picked up the sack quickly and held it open while the tall boy lifted Jenny and dropped her into it. A girl in front of Jenny took her hand ands 91 her until Jenny gained her balance. Then she jumped forward, smiling and proud. In the cheers of teachers, schoolmates and parents, I silently thanked Heaven for the warm, understanding people in life who make itp 92 for my disabled daughter to be like her fellow human beings. Then I finally cried.86____ 87_____ 88______ 89_____ 90______ 91______ 92______D)Answer the questions(12分)A different kind of alarm clockWhen Matty Sallin, 34, was studying art and technology at New York University, he got an interesting task for the final exam: Create something for the ordinary family. He decided to create an alarm clock."To get up in time, many people have to use an alarm clock every morning. But the sound of the clock is extremely noisy and unpleasant," he says. So before he started to design the new clock, he asked different people what they'd like to wake up to in the morning. A lot of them said, "The smell of bacon (培根肉)So Sallin and his two classmates invented a new kind of alarm clock: a wooden box with a pig face and a digital (数码的)clock that uses the smell of cooking bacon to wake people up. He explains, "There's no danger of burning, because I built it carefully. It uses special light bulbs (灯泡)instead of a fire for cooking and turns off automatically after ten minutes." Just a few easy steps are required to set the "alarm"."What you do is to put a few pieces of bacon meat inside the box the night before, and then you set the alarm" says Sallin. "If you set the alarm for 8:00, it will turn on at 7:50 and slow cook for ten minutes under the bulbs. Then the bulbs turn off and a fan blows the smell out through the nose of the pig."So the pleasant smell of bacon will wake you up. There will be no more noisy alarms," says Sallin. "Then you can open the door on the side and pull the bacon out and eat it."When Sallin was a kid, he spent a lot of time making drawings of inventions. "I wanted to make a lift in my back yard and a special tree house" he says. "But I never really thought I'd become an inventor!"Sallin got an A for his alarm clock and went on to invent other things—but people continue to email him every day asking where they can buy his alarm clock. If he decides to produce and sell his special alarm clock, maybe he can build a successful business out of it.93.What was Matty Sallin?94.How many people worked together on the new alarm clock?95.How long did it take to cook the bacon?96.Why are light bulbs used for cooking bacon instead of a fire?Because________________ ____________97.What's special about Sallin's alarm clock?___ ________ wakes people up instead of the loud alarm.98,What do you think of the new alarm clock?VII.Writing(共20分)99.Write a passage of at least 60 words on the topic ______has helped/me to learn a lot,以________ 使我受益匪浅为题写一篇不少于60字的短文,标点符号不占格注意短文不得出现考生的姓名、学校及相关信息,否则不予评分Use the following points as a reference.

A. reminding B. remembering C. recalling D. reformingSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Not many people know about the clouded leopard. Even scientists don’t know much about the animal in the wild because it is so private. We do know that the clouded leopard isn’t actually a leopard. It is a species of its own. However, it does have spots like a leopard. They help it blend into the background in the forest.What else do we know about the cat? It is one of the best climbers of all wild cats. This skill is clearly imprinted in the kittens early on by their mothers and by instinct. In the wild, the cat lives in the tropical rain forests of Asia. It hunts small animals, such as squirrels and monkeys. It is listed on the United States Endangered Species Act. This protects it from being hunted. Scientists have speculated that the wild population is getting smaller, but no actual numbers are available.The Clouded Leopard Project works to conserve and protect the population of these cats. The project teaches about clouded leopards, analyzing their habits in captivity by watching their behaviors and interactions. The project realizes it is important to the cats’ survival to breed the animals in zoos. If more clouded leopards aren’t born, the population will be pushed quickly into extinction.The Clouded Leopard Project has recently begun a conservation effort in Thailand. It is a natural home of the clouded leopard. Funds will be given to the Khao Kheow Open Zoo to helpwith the breeding of these cats. Part of the money also will help save the habitat of the wild cats. People will work to monitor these wild cats. They will be photographed instead of being sedated, or drugged, to be tagged(加标签). Sedating clouded leopards could cause the cats’ bodies to lose too much water, or worse.The project has had some great successes in the last few years. Two cubs were born in the United States, and two were born in Thailand. Members of the Clouded Leopard Project hope the urge to protect such species will become embedded in people’s minds. They sponsor several education programs at zoos. They also sponsor programs to directly help the cats. Through their work they ultimately will increase the population of this species.65. What made a clouded leopard not easy to find in the forest?A. Spots like a leopard.B. A species of its own.C. Best climbing skills.D. Extinction of such animals.66. _____ is not included in the Clouded Leopard Project?A. Breeding clouded leopards in zoos.B. Monitoring the cats by labeling them.C. Starting educational programs at zoos.D. Sa ving the cat’s natural habitat.67. The underlined word “embedded” means _____.A. focusedB. rootedC. determinedD. talented68. Which of the following statement is TRUE?A. Clouded leopard is a rare kind of leopard with nice spots.B. Lack of food in the wild makes the survival of the cats more difficult.C. The Clouded Leopard Project aims at increasing the population of the cat.D. Observing clouded leopards’ behavior protects the cats from being hunted.(B)(C)With greenhouse gas emissions(排放)hitting record levels and passing climate scientist's worst predictions, a new group of Chinese activists is making its voice heard at the United Nations climate talks, the COP17, which was held in Durban, South Africa.The delegation of independent Chinese non-governmental organizations (NGOs) believes that civil society must play a bigger role in the global climate crisis. C Plus is the name given to the project launched by 42 Chinese NGOs, calling for domestic and global action to fight climate change. And they think the best way of demanding governments' action is to take action by themselves. The message is clear: climate action is too important and too urgent. It can't wait. The top-down process of negotiations that we are seeing at the UN is too slow.C Plus has three components, which together explain its name. C Plus stands for: Beyond Commitment. This means that NGOs must put pressure on their governments to achieve targets that are beyond those that have been officially stated. Second is Beyond China -- in other words, NGOs outside and inside of China together must strive to influence their respective governments to take action. Finally, Beyond Climate. The project targets not just carbon reduction but other environmental measures as well such as clean water and air, public education, water conservation and preservation of forests.In the last few years, NGOs have played an active role in influencing the government's policy making, supervising the government's task of environment responsibility and raising public awareness in environment protection.And NGOs can claim some notable successes. NGOs sponsored “26-degree air conditioning office”among the public, which later became a government regulation. A group of Chinese citizens organized together and stopped the construction of a dangerous chemical plant in Xiamen.In total, there are 3,539 environment NGOs in China, in which 55.2 percent now have their own offices, and 26 percent have fixed source of investment. However, most environment NGOs still face problems including difficulty in raising money, shortage in personnel and weak organization ability in their development process.In Durban, Chinese NGOs have arrived as a team and are prepared to state their demands.72. The passage is mainly about _____.A. Durban climate change conferenceB. environment NGOs in ChinaC. C plus project launched by NGOsD. achievements of NGOs73. Which of the following is true about the C Plus?A. It is an organization devoted to controlling the greenhouse gas emission.B. It is a program aiming at influencing government to take action to protect environment.C. It is a project designed by the government to unite NGOs inside and outside China.D. It is a statement calling for public awareness in environment protection.74. Most environment NGOs don’t lack _____.A. financial supportB. human resourcesC. development goalsD. organizational skills75. What can be inferred from the passage about the NGOs?A. They once pushed the government to make a regulation concerning office temperature.B. They pushed forward the slow negotiations by adopting the top-down style.C. They were directly involved in making environment-related policies.D. They successfully pressurized the government to achieve the unofficially stated targets. Section CDirections: Read the following text and choose the most suitable heading from A-F for eachAutism is a disorder of early development that causes severe problems in thinking, communicating with others, and feeling a part of the outside world. Taken from the Greek word autos meaning “alone,” autism prevents children from developing normal social relationships, even with their parents.Not all autistic infants and children are alike; in fact, there is no single typical clinical picture of the disorder. However, certain types of behavior are noted in a majority of autistic children. Autistic infants will not cuddle, and they do not like to be picked up. The usual things that children do to imitate adults, such as waving goodbye, are not observed in autistic children. Instead, autistic children very often repeat such movements as flicking a hand, twisting an arm or leg, or banging the head over and over. Strange gestures and distorted facial expressions are common.Language develops slowly, if at all. Some autistic children remain totally silent, while others merely repeat words they hear or communicate by gestures. They have little or no interest in making friends. They smile rarely, if ever, and will avoid making eye contact. Unlike normal children, they tend to fixate on a single object or task, such as spinning the wheels on a toy car over and over.At one time autism was blamed on bad parenting. Now it isbelieved to be caused by abnormalities in the brain. Several possible causes of these abnormalities have been proposed: an illness the mother suffered during her pregnancy; too little oxygen at the time of birth; or possibly an abnormal gene. In some cases, X rays have revealed abnormalities in the structure of the brainitself. There is no way to diagnose autism apart from observing the child's behavior closely over a period of time.Although some patient-tailored programs can help children function better, the life of these children is generally hard to predict. Some will remain severely impaired throughout their lives. A majority always will depend heavily on support from relatives and professional caregivers, and may require special living arrangements and close supervision. However, progressive changes in the treatment of these children have enabled about one in six to live independently and work productively. What’s more, the intelligence level of the child partly affects the ability to function.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.If you have been following the news you will know that the world’s population recen tly reached seven billion – probably on 31st October.The statistics concerning human population growth are astonishing. It was only 12 years ago, in 1999, that the world’s population reached six billion. In 1969 there were 3.5 billion people on the planet, which is to say our numbers have doubled in only 42 years. A century ago, in 1911, there were only 1.8 billion of us: 26% of today’s total.As for future population growth, it seems there will probably be eight billion people by 2030 and nine billion by around 2050. After that, predictions vary: many experts think the total will rise more slowly, perhaps reaching ten billion by the end of the century; but a few believe the fast rise might continue, leading to a global population of as many as 15 billion by 2100.There are big differences between rates of population growth around the world. The fastest rates are generally in the world’s poorer countries, including those in sub-Saharan Africa, while the populations of rich countries are mostly growing much more slowly, or even shrinking in a few cases. (Germany and Japan, for example, will have smaller populations in 2050 than they do now.) This fact explains another interesting statistic: in 1900 Europe contained around 25% of the world’s people, but in 2050 it will have less than 10%.There are many reasons for fast population growth, but the most significant include medical advances and generally improved standards of living in poor countries, which mean fewer deaths from diseases or from malnutrition. Indeed, average life expectancy across the world has risen 20 years since the 1950s, from 48 to 68, and the biggest rises have been in poor countries.Some people already talk of a crisis of overpopulation, expecting there to be wars over access to natural resources and warning that, because those resources are limited, it is impossible for seven billion people (let alone nine or ten) to have the kind of high-consumption lifestyles that people in the world’s richer countries currently enjoy. Others, however,believe the planet can accommodate another two or three billion humans without a social or environmental disaster.We can only hope the optimists will be proved right.(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS)81. When was the world’s population half of what it is now?82. There seems to be a connection between a country’s rates of population and_________________________________________.83. What contributed to the fast population growth?84.

He can work while sitting in a comfortable chair if he wants. However, he prefers to stand most of the day while he is working."It feels more natural to stand. I feel more energetic," he said.In recent years, more and more American people have chosen to stand while they are working. There are many reasons. For example, standing makes people pay more attention to their work; standing stops them from feeling sleepy; standing while working makes them feel as if they are leaders.According to many reports, sitting for many hours a day is very bad for health. According to one report, people who sit more than six hours a day are at least 18% more likely to die earlier than those who sit less than three hours a day. The study was done on 123,000 adults and it studied them for over 14 years.Standing while working seems to provide people with a new, good way to live healthily. At the same time, some professors suggest that people also move around, rather than just stand while they work.Questions:11.Which is not the advantage of standing while working? (D)12. What’s the outcome of the study mentioned in the passage? (C)13. What’s the professors’ suggestion?

Their arrival in the UK is part of a 10-year China-UK joint research program studying how human-bred pandas can survive in the wild. "Tian tian", is expected to give birth during their decade in the UK.Xie Hao, care taker of the couple said: "The boy Yang guang is outgoing; he loves humans. He often approaches visitors and is loved by people. But the girl Tian tian is shy and sensitive, especially to strangers. It may take her longer to get used to their new home in the UK."The loan of the two pandas from China will cost the Royal Zoological Society of Scotland more than 600-thousand pounds, or 935-thousand US dollars a year,with another 70-thousand pounds for imported bamboo.Questions:14. Why were the two pandas sent to Scotland? (A)15. What makes Tian tian’s adaptation time longer? (B)16. How much does the imported bamboo cost every year?

It is a love story about acouple, with a happy ending that pleases everybody.M: That sounds nice. When is it being shown?W: Tomorrow at 6:15 pm in the Grand Cinema. Actually I’m not particularly interested in it. Anyway, I’ll go with you, for I don’t want to be alone at home.Blanks 21 through 24 are based on the following conversation.M: Good afternoon, madam. How can I help you?W: Well, I am a bit out of shape. I'm thinking about getting some exercises to keep fit.M: Oh, that's good news for us.W: So what do you provide?M: First of all, we'll design a custom-made work-out plan according to your habits.W: How can you get that done?M: Well, you have a qualified personal trainer assigned to you.

B19. 解:连接AC 、BD 交于O 点,连接PO ,则PO 就是正四棱锥的高设异面直线PA 与CD 所成角的大小θ,底边长为a ,则依题意得,正四棱锥P −ABCD 体积为V =13a 2×1=4 … ∴ a =2√3,可得AC =2√6Rt △PAO 中,OA =√6,PO =1∴ PA =√12+(√6)2=√7 …因为CD // AB ,所以直线PA 与AB 所成的锐角就是PA 与CD 所成角θ. …△PAB 中,PA =PB =√7,AB =2√3,∴ cos∠PAB =7+12−72×√7×2√3=√217,即cosθ=√217, 所以PA 与CD 所成角θ=arccos √217. … 20. 解:(1)∵ (2b −c)cosA −acosC =0,由正弦定理,得(2sinB−sinC)cosA−sinAcosC=0,∴ 2sinBcosA−sin(A+C)=0,sinB(2cosA−1)=0,∵ 0<B<π,∴ sinB≠0,∴ cosA=12,∵ 0<A<π,∴ A=π3.(2)∵ S△ABC=12bcsinA=3√34,即12bcsinπ3=3√34∴ bc=3①由余弦定理可知cosA=b 2+c2−32bc=12∴ b2+c2=6,②由①②得b=c=√3,∴ △ABC为等边三角形.21. 解:(1)①若f(x)=x3是“Ω函数”,则存在实数对(a, b),使得f(a+x)⋅f(a−x)=b,即(a2−x2)3=b时,对x∈R恒成立…而x2=a2−√b3最多有两个解,矛盾,因此f(x)=x3不是“Ω函数”…②若f(x)=2x是“Ω函数”,则存在常数a,b使得2a+x⋅2a−x=22a,即存在常数对(a, 22a)满足,因此f(x)=2x是“Ω函数”(2)解:函数f(x)=tanx是一个“Ω函数”,设有序实数对(a, b)满足,则tan(a−x)tan(a+x)=b恒成立当a=kπ+π2,k∈Z时,tan(a−x)tan(a+x)=−cot2x,不是常数;…因此a≠kπ+π2,k∈Z,当x≠mπ+π2,m∈Z时,则有(btan2a−1)tan2x+(tan2a−b)=0恒成立,所以btan2a−1=0且tan2a−b=0∴ tan2a=1,b=1∴ a=kπ+π4,k∈Z,b=1…∴ 当x=mπ+π2,m∈Z,a=kπ±π4时,tan(a−x)tan(a+x)=cot2a=1.因此满足f(x)=tanx是一个“Ω函数”的实数对(a, b)=(kπ±π4, 1),k∈Z…22. 解:(1)由x2=y得抛物线的焦点在y轴上,且2p=1,所以准线为y=−14…(2)解:由x2=y得抛物线的焦点在y轴上,且2p=1,所以,焦点坐标为(0, 14)…由A作准线为y=−14的垂线,垂足为Q,当且仅当三点P,A,Q共线时,|AP|+|AF|取得最小,最小值为6+14=254,…此时A 点的坐标为(2, 4)…(3)设点M 的坐标为(x, y),BC 边所在的方程过定点N(0, 1),… ∴ AM →=(x,y),MN →=(−x,1−y)∵ AM →⋅BC →=0∴ AM →⋅MN →=0,所以,−x ×x +y(1−y)=0,即y 2+x 2−y =0(x ≠0)…23. (1)解:∵ a 1=1,a n+1=f(a n ),n ∈N ∗,∴ a 2=35,a 3=37,a 4=13. …(2)解:由 a n+1=f(a n )=3a n 2a n +3 得 1a n+1−1a n =23,… 所以,{1a n}是首项为1,公差为23的等差数列 … (3)解:由(2)得1a n =1+23(n −1)=2n+13,a n =32n+1. … 当n ≥2时,b n =a n−1a n =92 (12n−1−12n+1),当n =1时,上式同样成立,… 所以s n =b 1+b 2+b 3+...+b n =92 (1−13+13−15+15−17+...+12n−1−12n+1)=92(1−12n+1).因为S n <m−20112,所以 92(1−12n+1)<m−20112 对一切n ∈N ∗成立,…又92(1−12n+1)随n 递增,且lim n →∞(1−12n+1)=92,所以,92≤m−20112, 所以,m ≥2020,m 的最小值为2020. …。

A. Therefore B. Besides C. Moreover D. However62. A. secure B. promise C. ensure D. influence63. A. overall B. quality C. alternative D. temporary64. A. reminding B. remembering C. recalling D. reformingSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Not many people know about the clouded leopard. Even scientists don’t know much about the animal in the wild because it is so private. We do know that the clouded leopard isn’t actually a leopard. It is a species of its own. However, it does have spots like a leopard. They help it blend into the background in the forest.What else do we know about the cat? It is one of the best climbers of all wild cats. This skill is clearly imprinted in the kittens early on by their mothers and by instinct. In the wild, the cat lives in the tropical rain forests of Asia. It hunts small animals, such as squirrels and monkeys. It is listed on the United States Endangered Species Act. This protects it from being hunted. Scientists have speculated that the wild population is getting smaller, but no actual numbers are available.The Clouded Leopard Project works to conserve and protect the population of these cats. The project teaches about clouded leopards, analyzing their habits in captivity by watching their behaviors and interactions. The project realizes it is important to the cats’ survival to breed the animals in zoos. If more clouded leopards aren’t born, the population will be pushed quickly into extinction.The Clouded Leopard Project has recently begun a conservation effort in Thailand. It is a natural home of the clouded leopard. Funds will be given to the Khao Kheow Open Zoo to help with the breeding of these cats. Part of the money also will help save the habitat of the wild cats. People will work to monitor these wild cats. They will be photographed instead of being sedated, or drugged, to be tagged(加标签). Sedating clouded leopards could cause the cats’ bodies to lose too much water, or worse.The project has had some great successes in the last few years. Two cubs were born in the United States, and two were born in Thailand. Members of the Clouded Leopard Project hope the urge to protect such species will become embedded in people’s minds. They sponsor several education programs at zoos. They also sponsor programs to directly help the cats. Through their work they ultimately will increase the population of this species.65. What made a clouded leopard not easy to find in the forest?A. Spots like a leopard.B. A species of its own.C. Best climbing skills.D. Extinction of such animals.66. _____ is not included in the Clouded Leopard Project?A. Breeding clouded leopards in zoos.B. Monitoring the cats by labeling them.C. Starting educational programs at zoos.D. Sa ving the cat’s natural habitat.67. The underlined word “embedded” means _____.A. focusedB. rootedC. determinedD. talented68. Which of the following statement is TRUE?A. Clouded leopard is a rare kind of leopard with nice spots.B. Lack of food in the wild makes the survival of the cats more difficult.C. The Clouded Leopard Project aims at increasing the population of the cat.D. Observing clouded leopards’ behavior protects the cats from being hunted.(B)(C)With greenhouse gas emissions(排放)hitting record levels and passing climate scientist's worst predictions, a new group of Chinese activists is making its voice heard at the United Nations climate talks, the COP17, which was held in Durban, South Africa.The delegation of independent Chinese non-governmental organizations (NGOs) believes that civil society must play a bigger role in the global climate crisis. C Plus is the name given to the project launched by 42 Chinese NGOs, calling for domestic and global action to fight climate change. And they think the best way of demanding governments' action is to take action by themselves. The message is clear: climate action is too important and too urgent. It can't wait. The top-down process of negotiations that we are seeing at the UN is too slow.C Plus has three components, which together explain its name. C Plus stands for: Beyond Commitment. This means that NGOs must put pressure on their governments to achieve targets that are beyond those that have been officially stated. Second is Beyond China -- in other words, NGOs outside and inside of China together must strive to influence their respective governments to take action. Finally, Beyond Climate. The project targets not just carbon reduction but other environmental measures as well such as clean water and air, public education, water conservation and preservation of forests.In the last few years, NGOs have played an active role in influencing the government's policy making, supervising the government's task of environment responsibility and raising public awareness in environment protection.And NGOs can claim some notable successes. NGOs sponsored “26-degree air conditioning office” among the public, which later became a government regulation. A group of Chinese citizens organized together and stopped the construction of a dangerous chemical plant in Xiamen.In total, there are 3,539 environment NGOs in China, in which 55.2 percent now have their own offices, and 26 percent have fixed source of investment. However, most environment NGOs still face problems including difficulty in raising money, shortage in personnel and weak organization ability in their development process.In Durban, Chinese NGOs have arrived as a team and are prepared to state their demands.72. The passage is mainly about _____.A. Durban climate change conferenceB. environment NGOs in ChinaC. C plus project launched by NGOsD. achievements of NGOs73. Which of the following is true about the C Plus?A. It is an organization devoted to controlling the greenhouse gas emission.B. It is a program aiming at influencing government to take action to protect environment.C. It is a project designed by the government to unite NGOs inside and outside China.D. It is a statement calling for public awareness in environment protection. 74. Most environment NGOs don ’t lack _____.A. financial supportB. human resourcesC. development goalsD. organizational skills 75. What can be inferred from the passage about the NGOs?A. They once pushed the government to make a regulation concerning office temperature.B. They pushed forward the slow negotiations by adopting the top-down style.C. They were directly involved in making environment-related policies.D. They successfully pressurized the government to achieve the unofficially stated targets. Section CDirections: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.Autism is a disorder of early development that causes severe problems in thinking, communicating with others, and feeling a part of the outside world. Taken from the Greek word autos meaning “alone,” autism prevents children from developing normal social relationships, even with their parents.Not all autistic infants and children are alike; in fact, there is no single typical clinical picture of the disorder. However, certain types of behavior are noted in a majority of autistic children. Autistic infants will not cuddle, and they do not like to be picked up. The usual things that children do to imitate adults, such as waving goodbye, are not observedin autistic children. Instead, autisticchildren very often repeat such movements as flicking a hand, twisting an arm or leg, or banging the head over and over. Strange gestures and distorted facial expressions are common.Language develops slowly, if at all. Some autistic children remain totally silent, while others merely repeat words they hear or communicate by gestures. They have little or no interest in making friends. They smile rarely, if ever, and will avoid making eye contact. Unlike normal children, they tend to fixate on a single object or task, such as spinning the wheels on a toy car over and over.At one time autism was blamed on bad parenting. Now it is believed to be caused by abnormalities in the brain. Several possible causes of these abnormalities have been proposed: an illness the mother suffered during her pregnancy; too little oxygen at the time of birth; or possibly an abnormal gene. In some cases, X rays have revealed abnormalities in the structure of the brain itself. There is no way to diagnose autism apart from observing the child's behavior closely over a period of time.Although some patient-tailored programs can help children function better, the life of these children is generally hard to predict. Some will remain severely impaired throughout their lives. A majority always will depend heavily on support from relatives and professional caregivers, and may require special living arrangements and close supervision. However, progressive changes in the treatment of these children have enabled about one in six to live independently and work productively. What’s more, the intelligence level of the child partly affects the ability to function.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.If you have been following the news you will know that the world’s population recently reached seven billion – probably on 31st October.The statistics concerning human population growth are astonishing. It was only 12 years ago, in 1999, that the world’s population reached six billion. In 1969 there were 3.5 billion people on the planet, which is to say our numbers have doubled in only 42 years. A century ago, in 1911, therewere only 1.8 billion of us: 26% of today’s total.As for future population growth, it seems there will probably be eight billion people by 2030 and nine billion by around 2050. After that, predictions vary: many experts think the total will rise more slowly, perhaps reaching ten billion by the end of the century; but a few believe the fast rise might continue, leading to a global population of as many as 15 billion by 2100.There are big differences between rates of population growth around the world. The fastest rates are generally in the world’s poorer countries, including those in sub-Saharan Africa, while the populations of rich countries are mostly growing much more slowly, or even shrinking in a few cases. (Germany and Japan, for example, will have smaller populations in 2050 than they do now.) This fact explains another interesting statistic: in 1900 Europe contained around 25% of the world’s people, but in 2050 it will have less than 10%.There are many reasons for fast population growth, but the most significant include medical advances and generally improved standards of living in poor countries, which mean fewer deaths from diseases or from malnutrition. Indeed, average life expectancy across the world has risen 20 years since the 1950s, from 48 to 68, and the biggest rises have been in poor countries.Some people already talk of a crisis of overpopulation, expecting there to be wars over access to natural resources and warning that, because those resources are limited, it is impossible for seven billion people (let alone nine or ten) to have the kind of high-consumption lifestyles that people in the world’s richer countries currently enjoy. Others, however, believe the planet can accommodate another two or three billion humans without a social or environmental disaster.We can only hope the optimists will be proved right.(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS)81.
