A篇This document sets out the display standards for Glasgow Museums. This guide will help exhibition planners provide access to exhibitions in our museums. Glasgow Museums’ aim is to improve access to collections by having as many items as possible on display and without physicalbarriers. We also try our best to protect these objects without limiting access to them.Object Placement*Don’t place objects in such a way that they could present a danger to visitors.*All object displays, cased or otherwise, must be viewable by all, including people who are small in figure or in wheelchairs.Open Display*All objects on open display must be Secure from theft and damage.*All objects identified for potential open display must be viewed and agreed on an object-to-object basis byRecommendations DistanceRecommended distance to place objects out of “casual arm's 700mm length”700mm(taken from the edge of the object to the edge of any proposed form ofbarrier)Cased Objects*All cased displays should fall within the general optimum(最优的)viewing band of 750-2,000mm. Ensure everything is visually accessible from a wheelchair.*Position small objects or those with fine detail in the front part of a case, with larger items behind.*Position small items or those with fine detail no higher than 1,015mm from floor level. Objects placed abovethis height are only seen from below by people in wheelchairs or people who are small in figure.( )1. From this text, we can learn that Glasgow Museums______.A. limit access to exhibitions on a daily basisB. are most well-known for its large collectionC. make generous donations to the disabledD. give weight to the experiences of visitors( )2. According to the guide, objects to be placed on open display must______.A. be equipped with anti-theft systemB. be viewed from a distance of 700mmC. receive approval from the museum firstD. fall within arms' reach of a standing man( )3. A mother and her 10-year-old son are likely to both feel comfortable in front of a diamond placed in a glass case at the height of______.A.1,250mmB.950mmC.650mmD.450mmB篇In mammals, loud calls usually serve as alarm signals that warn fellow species of an enemy or other danger. On the other hand, screams from humans can have very different meanings, as Swiss researchers now report in the journal“PLoS Biology”. Human’s screams are not always only associated with negative emotions such as fear, pain, anger and grief, but also positive emotions such as joy and pleasure.Sascha Frihholz and his colleagues from the University of Zurichstudied how many types of human screams there are, how accurately test subjects can distinguish them, and which brain regions are involved(参与)in processing such sound signals. To do this, they first made sound recordings of different screams. Twelve men and women were to put themselves in situations where they reacted with a brief scream. The predetermined situations included, for example: an attack by an armed stranger, celebration about a sporting victory of their favorite team, the threat of an opponent.From the recordings, the researchers finally selected 420 screams. From this, they identified six distinct categories of screams, including three of alarming characters (cries of pain, anger, and fear) and three non-alarming screams ( as expressions of great pleasure, extreme joy, and desperate sadness). Contrary to all expectations, the subjects reacted to non-alarming screams more quickly and recognized the emotion expressed with it more reliably than with alarming screams. This was also confirmed by images of the brain using functional magnetic resonance imaging(FMR).“Until now, researchers assumed that humans also detect and process perceived alarm signals particularly quickly in the form of screams, as this is an important survival mechanism(机制),”says Frihholz. But unlike monkeys and other mammals, non-alarming screams would have become more important for communication.“This changed priority(优先)is probably due to needs that have evolved in the evolution of complex human social relationships."( )4. What does the text mainly talk about?A. Human’s screams expressions.B. An experiment launched in screams.C. Loud calls as a survival mechanism.D. Mammals' loud calls served as alarm signals.( )5. Which expression can be reacted to more quickly?A. Cries of pain.B. Anger.C. Fear.D. Desperate sadness( )6. What does the last paragraph convey?A. Monkeys are not sensitive to non-alarming screams.B. Humans survive because of quick reaction to screams.C. Non-alarming screams gain priority because of human’s revolution.D. Non-alarming screams make human social relationships more complex.( )7. What is the purpose of the text?A. To spread and advocate.B. To argue and discuss.C. To compare and inform.D. To recommend and introduce.C篇Good manners are always good manners. That's what I thought until I married Alexander, who is Russian.When I first met Alexander and he said to me in Russian, “Nalei mnye chai-pour me some tea.” I got angry and answered, “Pour it yourself." Translated into English, without a“please”, it sounded really rude to me. But in Russian it was fine-you don't have to add any polite words.However, when I took Alexander home to meet my parents in the UK, I had to give him a good lesson about pleases and thank-yous, and to teach him to smile, smile, smile.Another thing that Alexander just couldn't understand was why people say things like “Wouldyou mind passing me the salt, please?" He said, “It's only the salt, for God’s sake! What do you say in English if you want a real favour?”He also watched in amazement when, at a dinner party in England, we swallowed some really disgusting food and I said, “Mmmm... delicious." In Russia, people are much more direct. The first time Alexander's mother came to our house for dinner, she told me that my soup needed more flavouring. Afterwards, when we argued about it, my husband said, “Do you prefer your dinner guests to lie?"Alexander complained that in England he felt like an idiot because in Russia if you smile all the time people think you are mad. In fact, this is exactly what my husband's friends thought of me the first time I went to Russia because I smiled at everyone.At home we now have an agreement. If we're speaking Russian, he can say “Pour me some tea”. But when we're speaking English, he has to add a “please”, a “thank you”, and a smile.( )8.What can we know from what Alexander said?A. He didn't think politeness was necessary.B. He didn't like the writer's politeness.C. He wasn't used to the English politeness.D. He wasn’t willing to have good manners.( )9. What did Alexander's friends think of the author when they first met her?A.She was noble.B. She was strange.C. She was lovely.D. She was impolite.( )10. What can we learn from their agreement?A. They respect each other.B. They change a lot for each other.C. They learn from each other.D. They fail to fit in with each other.( )ll. What topic is the text mainly about?A. Good manners.B. Human relations.C. Culture shock.D. Mixed marriages.D篇What fisherman Moul Thun from a remote island in the Mekong River, in northern Cambodia, didn't know was that stingray(黄貂鱼) he hooked would eventually be named the largest recorded freshwater fish. For Zeb Hogan, who’s been documenting large freshwater fishes for almost two decades, the discovery of the stingray, which was released alive back into the river, filled him with hope. "It proves these underwater big fish, which are in critical danger, still exist," says Hogan.Hogan's pursuit for big fish, called the Megafishes Project and supported by National Geographic Society, began in 2005 when fishermen in northern Thailand pulled a 646 pound catfish out of the Mekong River. The species is known that it was the largest, that is, the heaviest-ever caught in the area.Arriving at the island, the team found Thun's fish, a female that appeared to be in good health. It was more than 13 feet from nose to tail. The researchers were shocked to see her weight at 661 pounds. She set a new world record. The original aim of the Megafishes Project was to find, study, and protect the world's largest freshwater fishes. The project focused on species that could grow to at least the size of a human and that lived only in freshwater.Hogan initially drew up a list of roughly 30 species to focus on.The challenge, as Hogan soon learned, was that many of these fish are hard to find. They live in remote, inaccessible places, and often in deep waters. Early on in the search, there were relatively few scientists studying them.What was clear was that the river giants were shrinking in number, threatened by a host of factors including overfishing, water pollution, and the presence of dams, which block migrating fish from completing their life cycles. As Hogan's work progressed, its focus increasingly turned to conservation. “It was never about just finding the biggest fish,” Hogan says, “but looking for ways to protect these extraordinary animals that, in some cases, have been on Earth for hundreds of millions of years but are now drifting out of entities."( )12. Why was Zeb Hogan full of hope?A. Freshwater fishes weren’t in danger.B. Some large fishes didn’t die out.C. The stingray was put into the river.D. Many large fishes existed in rivers.( )13. What can we know about the 646-pound catfish?A. It was also caught by Moul Thun.B. It's the largest recorded freshwater fish.C. It was injured very seriously.D. It was caught in the Mekong River.( )14. Which of the following is the original goal of the Megafishes Project?A. Finding about 30 species of big fishes.B. Studying fishes smaller than humans.C. Protecting big freshwater fishes.D. Setting new record in finding fishes.( )15. What does the underlined part “drifting out of entities" in the last paragraph mean?A. Dying outB. Getting illC. Being protected.D. Living well.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
