The increasingly popular "design museums" that are opening today, however, perform quite a different role. Unlike most art museums, the design museum shows objects that are easily found by the general public. These museums sometimes even place things like fridges and washing machines in the center of the hall.People have argued that design museums are often made use of as advertisements for new industrial technology. But their role is not simply a matter of sales—it is the honoring of excellently invented products. The difference between the window of a department store and the showcase in a design museum is that the first tries to sell you something, while the second tells you the success of a sale.One advantage of design museums is that they are places where people feel familiar with the exhibits. Unlike the average art museum visitors, design museum visitors seldom feel frightened or puzzled(困惑). This is partly because design museums clearly show how and why mass-produced products work and look as they do, and how design has improved the quality of our lives. Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something beyond their understanding.In recent years, several new design museums have opened their doors. Each of these museums has tried to satisfy the public's growing interest in the field with new ideas. London's Design Museum shows a collection of mass-produced objects from Zippo lighters to electric typewriters to a group of Italian fish-tins. The choices open to design museums seem far less strict than those to art museums, and visitors may also sense the humorous part of our society while walking around such exhibits as interesting and unusually attractive toys collected in our everyday life.41. Showcases in design museums are different from store windows because they ______.A. show more technologically advanced productsB. help increase the sales of productsC. show why the products have sold wellD. attract more people than store windows do42. The author believes that most design museum visitors ______.A. do not admire mass-produced productsB. are puzzled with technological exhibitsC. dislike exhibits in art museumsD. know the exhibits very well43. The best title for this passage is ______.A. The forms of design museumsB. The exhibits of design museumsC. The nature of design museumsD. The choices open to design museumsBFive or six years ago, I attended a lecture on the science of attention. A professor who conducts research over in the medical school was talking about attention blindness, the basic feature of the human brain that, when we concentrate on one task, causes us to miss just about everything else. Because we can't see what we can't see, our lecturer was determined to catch us in the act. He had us watch a video of six people tossing (投掷) basketballs back and forth, three in white shirts and three in black, and our task was to keep track only of the tosses among the people in white. The tape rolled, and everyone began counting.Everyone except me. I'm dyslexic (患阅读困难症的), and the moment I saw that tape with the confusing basketball tossers, I knew I wouldn't be able to keep track of their movements, so I let my mind wander. I became curious, though, when about 30 seconds into the tape, a gorilla (大猩猩) walked in among the players. She (we later learned a female student was in the gorilla suit) stared at the camera, beat her chest with her fist, and then went away while they continued passing the balls.When the tape stopped, the professor asked how many people had counted at least a dozen basketball tosses. Hands went up all over. He then asked who had counted 13, 14, and congratulated those who'd scored the perfect 15. Then he asked, "And who saw the gorilla?"I raised my hand and was surprised to discover I was the only person at my table and one of only three or four in the large room to do so. He'd set us up, trapping us in our own attention blindness. Yes, there had been a trick, but he wasn't the one who had played it on us. By concentrating so hard on counting, we had managed to miss the gorilla in the midst.Attention blindness is the fundamental organizing principle of the brain, and I believe that it presents us with a great opportunity. My take is different from that of many neuroscientists: Where they see the shortcomings of the individual, I sense an opportunity for cooperation. Fortunately, given the interactive(互动的) nature of most of our lives in the digital age, we have the tools to control our different forms of attention and take advantage of them.It's not easy to admit that everything we've learned about how to pay attention means that we've been missing everything else. It's not easy for us logical, intelligent, confident types to admit that the very key to our success — our ability to discover a problem and solve it, an achievement obtained in all those years in school and beyond — may be exactly what limits us. No one ever told us that our way of seeing left out everything else.44. Which of the following is true about the writer when the tape was played?A. Like everyone else, the writer was counting carefully.B. The writer had difficulty keeping track of the tossers' movements.C. The writer showed great curiosity about what the players were doing.D. The writer tried hard to stop her mind from wandering.45. What's the total number of basketball tosses by the players in white shirts in the video?A. 13.B. 14.C. 15.D. 30.46. Most of the people failed to notice the gorilla in the video because _____.A. they focused on the basketball tossing onlyB. they were trapped by the basketball playersC. they did not know what they were supposed to doD. they did not listen to the lecture carefully47. The word "take" (paragraph 5) most probably means _____.A. understandingB. impressionC. sceneD. preference48.In the writer's opinion, attention blindness ______.A. should be viewed as a shortcoming of the individualB. might be overcome if we can discover problems and solve themC. makes it possible for us to work together for a shared purposeD. helps us to become logical, intelligent and confident types of peopleCBelow are reviews for three books and two book series. Each has been read and loved by students across the country.The OutsidersThis book, first published in 1967. has become a classic for teens across the nation. It focuses on Ponyboy , who has been labeled all his life as a greaser. The greaser's opposing group is the " socs ". kids who have lots of money and can break any rules without getting in trouble. As the novel develops, S. E. Hinton allows the reader to see exactly how these labels affect teens in both the greaser and the soc group.If you've ever watched the movie The Outsiders, this story may sound familiar, as the movie was based on the book . The Outsiders gives teens a look into life in the 50's and 60's, offering timeless lessons that still apply to today's youth.Out of the Dus tAny student interested in the Great Depression and the Dust Bowl should read Out of the Dust by Karen Hesse. Hesse is able to capture the mood and spirit of this era through the use of poetry. The main character of the book, Billie Jo, is growing up in Oklahoma, the heart of the Dust Bowl. Through free verse poetry, Billie Jo narrates(讲述) her tale of poverty and survival during this difficult time.Out of the Dust is an excellent lesson in history . Due to the short length and writing style, the book is a quick but worthwhile read. By the end of the book, the reader is eager to start the story over again . Hesse is able to pack a lot of emotions and details into her short book , making the story very real and believable.The GiverThe Giver depicts a perfect society in which citizens experience no pain, have never felt fear,and life is completely under control. However, as the reader progresses through the story, it's easy to see that this community is far from utopia(乌托邦). Instead, through the experiences felt by the main character Jonas, the reader learns there is a missing from life in this world..During the Ceremony of the Twelves, each 12—year —old is assigned their life —long career in the community . Jonas is chosen to be the Receiver of Memories, a very special job assigned to oneperson at a time. When Jonas receives his training . he learns many truths about his community that change how he feels about his life, making him determined to do something to change it .The Giver is a good book for teens who enjoy science fiction and fantasy. The book makes you examine your own life, values, and beliefs, striving to find how you would define the perfect society.Anne of Green GablesThis eight-book series depicts the life of Anne Shirley, an orphan that is adopted in Prince Edward Island, Canada . The books are set in the 1800s to the 1900s, the last one taking place during World War I. Anne is a loveable spirit who has many misfortunes and laughable experiences when growing up and going to college.The Anne of Green Gables series is fun to read. creating a strong attachment to the reader and making the last book a bitter -sweet experience. Teenage girls who are looking for a female role model will love Anne Shirley.49. The greaser group may refer to those kids ______.A. who are poor in their lessons at schoolB. who are poor and often get into trouble for breaking rulesC. who go between the poor and the rich childrenD. who get along well with the soc group50. Which of the following is written in a poetic style?A. The Giver.B. The Outsiders.C. Out of the Dust.D. Anne of Green Gables.51. We can learn from The Giver that ______.A. everyone in the community can get a good jobB. Jonas is satisfied with his life in the communityC. people in the community live an imperfect lifeD. Jonas is loved by all the people in the community52. According to the passage, ______ may be chosen to be an example by teenage girls.A. Ponyboy B . Jonas. C. Billie Jo D. Anne ShirleyDIn the famous fairy tale, Snow White eats the Queen’s apple and falls victim to a curse; in Shakespeare’s novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pills that contained mercury, believing that it would make them immortal, but they died afterward.Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Aug 2014, reported The New York Times.The museum tour starts in a rainforest setting, where you can see live examples of some of themost poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren’t much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad (蟾蜍), the leaky batteries in the trash or the dirty pond water that did it.―Poisons can be bad for some things,‖ Michael Novacek, senior vice president of the museum,told NBC News. ―Yet they can also be good for others.‖This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment.The blood toxins of vampire bats, for example, can prevent blood from clotting (凝结), which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila monsters can lower the blood sugar of its victims, so it has been used to treat diabetes.The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances that we regularly take in – chili, coffee and chocolate, etc. – owe their special flavors or stimulating effects to chemicals that plants make to poison insects.53. By mentioning Snow White and Romeo at the beginning of the story, the author intends to____________.A. show that poison has long been involved in literatureB. show that poison is always linked with evil and deathC. draw readers’ attention to the topic of the articleD. get readers to think of more examples of the use of poison in stories54. What is the main purpose of the exhibition The Power of Poison?A. To give people more in-depth knowledge about poison.B. To teach people how to handle poisonous animals.C. To inform people about which animals are the most poisonous.D. To show how poison has been used for medical treatment.55. Which of the following statements about the exhibition is TRUE according to the article?A. The exhibition will lead visitors to a real rainforest.B. Golden poison frogs are the most poisonous animals on display.C. Those who visit the exhibition can join in some iPad-based interactive games.D. Visitors can listen to lectures on recent studies of poisonous animals.EWhat is funny? The short answer is: Who knows? The joke that causes a burst of laughter from one listener might be met with a puzzled look from another.In general, you should avoid jokes at any business or social gathering where there are more than two people in your conversational group. If there are only two people — and they consist of you and your best friend — go ahead and tell it.Admittedly, a few people possess a perfect sense of timing, appropriateness, and joke delivery.You are probably not one of them. You might be quite funny and have many great jokes. Butthere's a place for jokes — over dinner with family, hiking with friends, but business or social affairs with colleagues and acquaintances(熟人) are not it. It takes a whole other level of joke-telling ability to put a joke into the more formal conversations.The best jokes come into the conversation so that by the time listeners realize a joke is in progress, the punchline that produces humour is being delivered — to their surprise and delight.Jokes don't translate well when you're in a group with mixed backgrounds: those whose first language is not English, those who might not understand a special term or an "in" expression, young people who wouldn't catch a reference to some bit of culture familiar to older people —and viceversa(反之亦然).Never joke about another person in the group — about their name, habits, hometown, profession, appearance, or past. It's not a question of whether the joke is cheery or appropriate. No one enjoys being singled out this way. When you are the subject of the joke, the laughter doesn't feel good no matter how hard you try to tell yourself they're not laughing at you. Because that's what it feels like.What do you say if you realize your joke upset someone? Apologize as briefly and as sincerely as you can, and hope that someone changes the subject. Try saying: "I'm sorry. I should have known better" or "I'm sorry. I wasn't thinking."What do you do if people don't get your joke or don't appear to find it as funny as you do? First, do not retell it, only louder this time, hoping the point of the joke will be seen. Second, don't try to push people to get it. People do not like people whose jokes they don't understand. They feel stupid and need to blame someone. If you want to leave with the goodwill of your listeners, say something to make them feel less foolish. You could say: "I don't know why I tell jokes when I'm so poor at it."The world needs laughter, and good humor is a success wherever it goes, so this caveat(告诫) about joke-telling is not meant to dampen high spirits or to advocate dull conversation. If you're a gifted story-teller and you know people love your jokes, go for it. We need your kind. The rest of us will save our jokes for family and close friends.56. According to the passage, it might be appropriate for you to tell a joke at a business or socialgathering if ______.A. the joke is well chosenB. you have complete confidence in your listeners' sense of humorC. only you and your best friend are involved in the conversationD. the audience consists of your colleagues and acquaintances57.Why do some jokes fail to work?A. Because the punchline is too long to catch.B. Because the joke-teller uses wrong words and expressions.C. Because the joke-teller and listeners don't share the same background knowledge.D. Because the jokes are not properly translated into the listeners' native language.58. How will people feel when they are joked about?A. They will feel happy if the joke is a pleasant one.B. They will be upset no matter what kind of joke it is.C. They will enjoy the joke when realizing that people are not laughing at them.D. They will panic because it makes them the center of attention.59. When people do not understand a joke they hear, they tend to ______.A. believe it's the joke-teller's faultB. get someone to retell the jokeC. ask for explanationD. say something foolish60. Which of the following best describes the writer's opinion on joke-telling?A. Nobody knows what makes a joke funny.B. We should not tell jokes unless we are asked to do so.C. Joke-telling is a very complex thing.D. Jokes should be told only to friends and family members.2014年下学期高二阶段性考试答题纸第一节单词拼写(共10小题,每小题1分,满分10分)61.

直到目前为止,绝大多数对丝绸之路的研究是把丝绸之路作为一条实存的道路来研究,这当然是无可厚非的。

但是,也正是这种坚持对史实的研究,使得丝绸之路的另一项作用,即它在文学上所起的作用在很大程度上被忽视了,因为对于绝大多数人来说,丝绸之路还是一条传闻中的道路,一条存在与想象中的道路。

那些出于各种目的而四处流动的人,商人、旅行家、冒险者和传教僧,也许他们不是决定习性,但却是丝绸之路上文化传播最为活跃的因素。

他们在求取自己目的的同时,也把自己的信仰、途中的见闻以及关于其他地方的种种信息,沿途撒播,并随时吸取新的信息,以作新的谈资。

他们的谈论,由于目的不同而各有取舍,再加上口头传播的随意性以及临时的即兴表演,都使得信息本身的真实性得到削弱,而臆想的成分却在加强,于是千奇百怪的事情都可以在丝路上的某一时段某一点发生了。

总之,他们在传播神话的同时又在制造着神话,在取信于听众和取悦于观众上极尽所能地发挥着天赋。

以丝路道路的艰辛和古人对神的虔诚,我们不难想见,神们自然会与他们一道辗转流动,这使得丝绸之路又成为一条神话传播的大道。

但是,信任总是有底线的,在信息来源极度缺乏的地区,人们比较容易相信外来的传闻,而在丝绸之路这样一个各种信息汇聚的场所,却更容易培养出人们的怀疑精神。

特别是在同一个地方流传着关于同一个人或者同一件事的各种相互矛盾的传闻的时候,人们往往就面临选择了。

有趣的是,人们在做选择时的态度,他们更倾向选择那些和精神深处密切相关的事物作为应该相信的对象,并以此来印证和加固传统的信仰,也就是说,比起真相来,人们更容易选择他们一贯相信和愿意相信的事作为“事实”,而其他的事,哪怕是确曾发生,也会慢慢地被当做奇闻轶事来处理。

好在人们对奇闻轶事的兴趣,一点也不逊色他们对“真相”的追求。

技术与人的关系,是一个不断演变的历史过程。

在手工劳动中,原始技术同劳动者不可分离。

手工劳动的技术,是最原始的技术,表现为劳动者的技能,即手控制手工工具的能力,亦称手工技能。

这种原始技术本质上是人的体能。

人的体能有两种功能:一是改变物体状态的能力,即体力。

二是控制物体的能力,在手工劳动中就表现为控制手工工具的能力。

这就是最早的技术——体技或手技。

所有的技术都是人对自己的超越。

人的双手的动作不准确、不精确,而手工技术追求的就是一准二精。

这种准确性和精确性的提高,不是通过工具,而是通过劳动者的苦练得来的。

“熟能生巧”,这“巧”是手之巧,靠的是熟练。

手工技能是由双手的动作的准和精表现出来的,它在一定程度上超越了人的生理局限,提高了人的生理功能,是“生理性技术”。

手工技能很难用语言文字来表达,它本身也不是知识,也不需要知识作为前提条件。

它只可意会,不可言传。

别人要学习这种技能,主要靠动作的模仿和用心去领悟。

这种技术的传授必须面对面进行。

这种手工技能是劳动者的身体所具有的,存在于劳动者体内,离开了劳动者的双手,这种技能就不再存在。

这种技能与其说是“社会的”,不如说是个人的,它不可能在空间上大规模传播,也不可能在时间上世代相传。

由于人具有高度的个性,所以手工技能也具有一定的个性。
