But arts groups bring broader value to our communities. The economic impact of the arts is often overlooked and badly judged.The arts create jobs that help develop the economy. Any given performance takes a tour bus full of artists, technical experts, managers, musicians, or writers to create an appealing piece of art. These people earn a living wage for their professional knowledge and skills.Another group of folks is needed to help market the event.“If you build it they will come”is a misleading belief. Painters, digital media experts, photographers, booking agents and promoters are hired to sell tickets and promote the event. According to the Dallas Area Cultural Advocacy Coalition, arts agencies employ more than 10,000 people as full- or part-time employees or independent contractors.A successful arts neighborhood creates a ripple effect(连锁反应) throughout a community. In 2005, when the Bishop Arts Theatre was donated to our town, the location was considered a poor area of town. After investing more than $1 million inreconstructing the building, we began producing a full season of theater performances, jazz concerts, and year-round arts education programs in 2008. Nearly 40 percent of jazz lovers live outside of the Dallas city limits and drive or fly in to enjoy an evening in the Bishop Arts District.No doubt the theater has contributed to the area’s development and economic growth. Today, there are galleries, studios, restaurants and newly built work spaces where neighbors share experiences, where there is renewed life and energy. In this way, arts and culture also serve as a public good.TeCo Theatrical Productions Inc. made use of Bloomberg’s investment of $35,000 to get nearly $400,000 in public and private sector support during thetwo-year period. Further, Dallas arts and arts-based businesses produce$298 for every dollar the city spends on arts programming and facilities. In Philadelphia, a metro area smaller than Dallas, the arts have an economic impact of almost $3 billion and support 44,000 jobs, 80 percent of which actually lie outside the arts industry, including accountants, marketers, construction workers, hotel managers, printers, and other kinds of art workers.The arts are efficient economic drivers and when they are supported, the entire small-business community benefits.It is wrong to assume arts groups cannot make a profit. But in order to stay in business, arts groups must produce returns. If you are a student studying the arts, chances are you have been ill-advised to have a plan B. But those who truly understand the economic impact and can work to change the patterns can create a wide range of career possibilities.第三节书面表达请认真阅读下面有关我国中小学生学业负担过重的柱状图及相关文字,并按照要求用英语写一篇150词左右的文章。

ASUBSCRIPTIONS FROM EUROPE/REST OF THE WORLD (ROW)1. Who will pay least if people subscribe to the same materials?A. People form Spain.B. People from France.C. People from the USA.D. People from China.2. How much will your school pay for one set of Hot English for students and one for teachers for class use totally?A. ￡185.4.B. ￡217.8.C. ￡212.8D. ￡235.4.B.That competition keeps prices down is well known. But it is hard to measure by just how much, because prices vary for all sorts of reasons, from differences in labour costs and rents to taxes. Rising to the challenge is a new paper in The Economic Journal by Giacomo Calzolari, Andrea Ichino, Francesco Manaresi and Viki Nellas, economists at the European University Institute, Bologna University and the Italian central bank. They looked at pharmacies(药房) and specifically at customers who may be particularly easy to rip off: new parents.Using data for 2007 to 2010 covering about a fifth of pharmacies in Italy, the researchers measured the way in which prices of hygiene products for babies changed as the number of babies varied. They took advantage of a peculiar law from the 195s, according to which regions with at most 7,500 people are allowed just one pharmacy (supposedly to keep the quality of services high). They compared prices in places with populations just below this threshold, and just above.The products studied included some 3,000 varieties of shampoos, bath foams, baby wipes, creams and so on. Many are also used by adults on themselves. Some people, for example, prefer sun-cream labeled “for children” because of its high level of protection. When raising prices for these products, even a pharmacist with a monopoly(垄断) must consider the risk that adult users will switch to products that are not aimed at children. But a rise in the number of babies, and hence buyers who are parents, could tip the scales towards price increases. By contrast, the pharmacist should already be charging as much as parents are willing to pay for products without adult users, such as nappies.The scholars found that pharmacists raised prices when there were more new parents----but only in regions with a single pharmacy, and not for nappies. In monopoly areas a doubling of the number of babies from one month to the next (not unusual in a small population) coincided with a 5% increase in the price of the basket of baby-hygiene products.The study is timely. Italy’s government has started to loosen some of the many restrictions that stop competition in the pharmacy sector (though not yet the one that the researchers relied on). But such regulations are plentiful in many other lines of business, and not just in Italy. The consumers who pay the price are often those who find it hardest to travel to shop around----for example, people with crying babies on their hands.3. What’s the purpose of the study?A. To review the function of the special law for pharmacies.B. To make clear the relation between competition and prices.C. To collect the information on pharmacy business in Italy.D. To gather the data on hygiene products for babies in Italy.4. “tip the scales” in Paragraph 3 means “_____”.A. Push the moveB. Keep the levelC. Control the riseD. Break the balance5. The government’s new measures will greatly benefit _____.A. pharmacy ownersB. local merchantsC. new parentsD. adult usersC.Listen carefully to the footsteps in the family home, especially if it has wooden floors, and you can probably work out who it is that is walking about. The features most commonly used to identify people are faces, voic es, finger prints and retinal scans. But their “behavioural biometrics”, such as the way they walk, are also giveaways.Researchers have, for several years, used video cameras and computers to analyse people’s gaits, and are now quite good at it. But translating such knowledge into a practical identification system can be tricky----especially if that system is supposed to be hidden. Cameras are often visible, are hard to set up, requi5re good lighting and may have their view blocked by other people. So a team led by Krikor Ozanyan of the University of Manchester, in England and Patricia Scully of the National University of Ireland, in Galway have been looking for a better way to recognize gait. Their answer: pressure-sensitive mats.In themselves, such mats are nothing new. They have been part of security systems for donkeys’ years. But Dr. Ozanyan And Dr. Scully use a complex version that can record the amount of pressure applied in different places as someone walks across it. These measurements form a pattern unique to the walker. Dr. Ozanyan and Dr. Scully therefore turned, as is now common for anything to do with pattern recognition, to an Artificial Intelligence system that uses machine learning to recognize such patterns.It seems to work. In a study published earlier this year the two researchers tested their system on a database of footsteps trodden by 127 different people. They found that its error rate in identifying who was who was a mere 0.7%. And Dr. Scully says that even without a database of foo tsteps to work with the system can determine someone’s sex---women and men, with wide and narrow pelvises(骨盆) respectively, walk in different ways,---- and guess, with reasonable accuracy, a subject’s age.A mat-based gait-recognition system has the advantage that it would work in any lighting conditions----even pitch-darkness. And though it might fail to identify someone if, say, she was wearing stilettos and had been entered into the database while wearing trainers, it would be very hard to fool it by imitating the gait of an individual who was allowed admission to a particular place.The latest phase of Dr. Ozanyan’s and Dr. Scully’s project is a redesign of the mat. The old mats contained individual pressure sensors. The new ones contain optical fibres(光纤). Light-emitting diodes(二极管) distributed along two neighbouring edges of a mat transmit light into the fibres. Sensors on the opposite edges( and thus the opposite ends of the optical fibres) measure how much of that light is received. Any pressure applied to part of the mat causes a distortion(变形) in the fibres and a consequent change in the amount of light transmitted. Both the location and amount of change can be plotted and analyzed by the machine-learning system.Dr. Ozanyan says that the team have built a demonstration fibre-optic mat, two meters long and a metre wide, using materials that cost ￡100($130). They are now talking to companies about commercializing it. One application might be in health care, particularly for the elderly. A fibre-optic mat installed in a nursing home or an old person’s own residence could monitorchanges in an individual’s gait that warn certain illnesses. That would provide early warning of someone being at greater risk of falling over, say, or of their cognition becoming damaged.Gait analysis might also be used ass a security measure in the workplace, monitoring access to restricted areas, such as parts of military bases, server farms or laboratories dealing with harmful materials. In these cases, employees would need to agree to their gaits being scanned, just as they would agree to the scanning of their faces or retinas for optical security systems.Perhaps the most fascinating use of gait-recognition mats, though, would be in public places, such as airports. For that to work, the footsteps of those to be recognized would need to have been stored in a database, which would be harder to arrange than the collection of mugshots and fingerprints that existing airport security systems rely on. Some people, however, might volunteer for it. Many aircrew or pre-registered frequent flyers would welcome anything that speeded up one of the most tiresome parts of modern travel.6. Camera-based gait recognition fails to come into wide use, because _____.a. it’s not easy to find the camerasb. finger print recognition is still popularc. sometimes the cameras can be coveredd. it’s a waste of money to fix the equipmente. good lighting conditions can’t be guaranteedf. it’s difficult to set up the system.A. acfB. bdeC. cdfD. cef7. Which of the following statements is TRUE according to Paragraph 6-8?A. The new mats function greatly with individual pressure sensors built in.B. The new mats will be likely to work better with enough pressure.C. The elderly are cured of their diseases with the monitor of the fibre-optic.D. Restricted areas are accessible to those with their gaits scanned beforehand.8. What does “it” refer to in Paragraph 5?A. The mat-based gait-recognition systemB. The gait stored in the databaseC. The advantage of working in any light condition.D. The admission to a particular place.9. What’s the best title of the passage?A. Listen to your footstepsB. Applaud pattern recognitionC. Love the way you walkD. Better the mats you step onD“With depressingly few exceptions, performances are dull and lack vitality…After years of trying to convince myself otherwise, I now feel sure that balletis dying.”-----Jennifer Homans, Apollo’s AngelsIs ballet dead? Has the art form evolved to depression? Jennifer Homan s’s conclusion to her fascinating history of ballet, Apollo’s Angels, is worrying.It appears that ballet’s pulse continues to beat strongly, however, especially with a Tchaikovsky defibrillator attached. So why are some dance commentators arguing that ballet is dying? And do they have a point?“Ballet is dead”----“Ballet is dying”---all ring tones of Friedrich Nietzsche’s philosophical claim: “God is dead.” Headline grabbling, certainly. Yet can ballet be defined in such black andwhite terms? Surely it is more abstract, filled with shades of popular grey. ①To start with, how do you define ballet? What is ballet today? Consider popular modern classics like Twyla Tharp’s In the Upper Room, where dancers wear pointy shoes and sneakers, combining contemporary and classical vocabulary together. Or closer to home, there is Graeme Murphy’s Swan Lake, which layers elements of Petipa’s choreography(编舞) with a contemporary theme and aesthetic. Many contemporary choreographers all embrace classical form and principles, then manipulate(操纵) the rules. ② .The line between contemporary dance and ballet is vague. In an interview with The Telegraph (2015), British choreographer Mattew Bourne acknowledges that this “cross-fertilisation” between contemporary dance and ballet continues to grow, as evidenced by the rise in new commissions from contemporary choreographers at the Royal Ballet and English National Ballet. Referring to Homans’s book, Bourne believes what has changed is that “the dance forms are coming closer together”. Not dying, but merging. Reinventing. This has been the case amongst Australasian ballet companies for many years now. ③ .Homans writes that ballet’s decline began after the passing of Ashton and Balanchine. Something ahs changed, certainly. A stylisic transition----from neo-classical to contemporary ballet----has occurred. ④Our art form’s evolution has always been with extinction. Prominent dance critic with The New York Times, Alastair Macaulay, says: “ballet has died again and again over the centuries,” and yet, “phoenix-like, rose again from its ashes”. History shows there were periods where ballet hibernated and lacked popularity. This coincided with the art form’s changing forums.So here is the irony: what sells best, still, are reproductions of Petipa’s classics. A season without a Tchaikovsky score is a financial risk. And without Nutcracker(《胡桃夹子》), half the ballet companies in North America would not exist. Admittedly, as a dancer, my favourite roles---Albrecht, Prince Siegfried and Romeo----were from the classical canon; I am a traditionalist at heart (who loves to be challenged by good contemporary ballets). A part of the charm behind classical repertoire, for me, was in reproducing the glories of past greats. Classical ballet’s framework supports the modern process of bench-marking.Perhaps Jennifer Homans’s thoughts are not completely unfounded. Perhaps ballet is dying for some. Ballet’s evolution has been delayed by its audiences. And as Homans suggests in her epilogue, perhaps also by its creatives.Now here is a bold prediction. In line with the Royal Ballet’s programming in Brisbane this year----of Christopher Wheeldon’s The Winter’s Tale, and Wayne MacGregor’s Woolf Works----over the next 20 years, ballet’s reliance on Petipa will decrease. Contemporary ballets and merge-styled ballets will produce their box-office influence ever more.Why?It is simple: our audiences will be ready for ballet to change again.10. Why does the writer cite Jennifer Homans’s words at the beginning of the passage?A. To support the writer’s viewpoint.B. To introduce the topic of the passage.C. To highlight the theme of the passageD. To provide the background knowledge.11. The sentence ‘Is this not ballet?” should be put in ______.A.①B. ②C. ③D. ④12. Which of the following statements is a fact about ballet?A. “Surely it is more abstract, filled with shades of popular grey.” (Para.3)B. “The line between contemporary dance and ballet is vague.” (Para.5)C. “Our art form’s evolution has always been with extinction.” (Para.7)D. “What sells best, still, are reproductions of Petipa’s classics.” (Para.8).13.

课时跟踪练(一) Warming Up & Reading — Pre-readingⅠ.阅读理解AEars are for hearing — everyone knows that. Butfor a creature called the Cuvier's beaked whale,hearing starts in the throat, a new study found.The observation might help explain how all whaleshear. The work might also help scientists understand how animals are affected by underwater sonar (声呐)．This sonar，used by some ships，sends out sound waves to locate underwater objects.The Cuvier's beaked whale is a socalled toothed whale. Toothed whales div e deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they're 1,000 meters under the sea, where it is totally dark.To better understand how the whale hears, researchers from San Diego State University in California took Xrays of two Cuvier's beaked whales. The whales had died and washed up on the beach.Ted Cranford and his colleagues used the images to make a computer model of a Cuvier's beaked whale's head. Then, they modeled the process of sound traveling through the head.The researchers knew that some sounds get to the ears of a toothed whale through a structure called “the window for sound”.Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.When the researchers used their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw.

But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.1. Which one is not mentioned about the benefits brought by the new map?A. Fisheries.B. Scientific projects.C. Ship manufacture.D. Oil exploration.2. What can we know about the new map?A. It shows where earthquakes will happen.B. It will be helpful to industry and governments.C. It is three times as detailed as the old one years ago.D. It shows the sea floor as it has ever been seen before.3. The text is likely to appear in _________.A. a newspaperB. an advertisementC. a science magazineD. a finance report4. Which of the following can be the best title for the text?A. The detailed picture of the oceansB. Underwater mountains and placesC. More discoveries about the oceansD. Scientists create new maps of ocean floorBRachel Louise Carson was born on May 27th, 1907 in Springdale, Pennsylvania. She grew up on a farm where she learnt about nature and animals. Rachel loved reading and writing stories when she was young. She even had a story published when she was only ten years old. One of Rachel’s favorite subjects was oceanology(海洋生物学).Rachel attended college at the Pennsylvania College for Women where she majored in biology. She later got her master’s（硕士）degree in zoology from John’s Hopkins Universit y. After graduation, Rachel taught for a while and then got a job at the U.S. Fish and Wildlife Service. At first, she wrote for a weekly radio program that educated people on marine（海洋的）biology. Later, she became a marine biologist and chief editor of publications for the Fish and Wildlife Service. In addition to her work at the Fish and Wildlife Service, Rachel wrote articles for magazines about the ocean. In 1941, she published her first book called Under the Sea Wind. However, her second book, The Sea Around Us, made her famous. The Sea Around Us was published in 1951 and was on the New York Times bestseller list for 39 weeks. With the success of the book, Rachel quit her job at the Fish and Wildlife Service and concentrated on writing full-time.After World WarⅡ, farmers began to use pesticides (农药) such as DDT on their crops. Rachel was concerned about the effects that large-scale spraying of DDT may have on the health of people as well as the environment. Rachel began to gather research material on pesticides and write a book about the subject.Rachel spent four years gathering research material and writing the book. She named it Silent Spring referring to bird death due to pesticides and the spring being silent without their songs. Published in 1962, the book became very popular and brought the environmental issues of pesticides to the general public.On April 14th, 1964, she died of breast cancer in her home in Maryland.5.

Rachel is believed to be more a biologist than a writer8. What type of writing is the article likely to be?A. A short story.B. A book review.C. A biography.D. A news report.Ⅲ. 七选五型阅读理解Four Steps to Begin Your Path to GreatnessFeeling stuck is quite common．Many times，we have thoughts and dreams of what we want in life．1Our thinking pattern holds us back from going forward．The good news is，at any moment in time，we have the ability to start taking action toward creating the life we want．Here are four steps to get started：◆Celebrate Your Success．Write down all the successes you’ve already achieved and all the awesomeness that you are today．2And once you’re in that positive routine with your thoughts，it will lead you to make better choices and take better actions toward your greatness．◆Create Your True Vision．Many times we live based on others’expectations or we stay stuck in a particular place because it’s our safety zone．Own your path．It can be hard to do，but allow yourself to get out of your head(or stop listening to what others want for you)and focus on your heart and what it’s telling you．3◆4.If you want to start going to the gym，going from 0 days a week to 5 days a week right away is extreme，and setting yourself up by biting more than you can chew typically doesn’t result in success，but failure．Instead，start slow and go once or twice a week．After you do that for a while and get into a nice routine，up it to more days．Over time，you will build toward your goal by taking realistic，smaller steps to get there.◆Have the Right Support．5Find the right support to cheer you on in the process．It could be a friend，a family member，or significant other who you trust．Whoever it may be，having someone on your journey will be just what you need to keep you on track and celebrate with you as you work toward the life you dream of．A．Don’t do it alone．B．Be realistic about your goals．C．Be kind to yourself and accept the moment．D．Your failure can lead you to another success．E．Sadly，they only stay as thoughts and dreams inside of us．F．This practice will direct your thinking to a positive place．G．Look within yourself deeply and decide what you want and what’s true for you．Ⅳ. 短文改错假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。
