考题 We all love a hero, and rescue dogs are some of the biggest heroes of all. You will often find them going above and beyond duty to save someone, risking--and at times losing--their lives in the process.Rescue dogs are generally found in the Sporting and Hunting Groups, or from the traditional Herding Group. These types include the Bloodhound, Labrador Retriever, Newfoundland, German Shepherd, Golden Retriever, and Belgian Malinois--all of which are chosen for search-and-rescue duty because of their amazing physical strength, loyalty, and their tendency for mental stability.These types also have a keen sense of hearing and smell--to better locate lost individuals—and are often able to access hard-to-reach areas. As highly trained animals, they serve in many different fields, including specialist search, snow slide rescue, dead body location, and tracking.To overcome obstacles and succeed when performing the demanding duties of a search-and-rescue worker, a dog must display certain qualities. In addition to intelligence and strength, the dog must be swift, confident, easily trainable, adaptable, and have a high level of stamina (耐力) and endurance. A strong sense of group cooperation and an ability to engage in friendly play during down time is also required of search-and-rescue dogs.A rescue dog goes through many, many hours of intensive training to be fit for duty. Training is not for the faint-hearted. Certification training can take from two to three years, working three to four hours a day, three to six days a week, often in group,team-oriented sessions.Each search-and-rescue field requires different types of training. Rescue training, for instance, includes air scenting--where dogs are trained to smell the air for the victim s scent (气味) and then follow the scent to the person. This ability is crucial to finding victims trapped under collapsed buildings and snow slide.40. Rescue dogs are chosen probably because__A.they are loyalB.they are braveC.they have amazing appearancesD.they have good eyesightWhat does "faint-hearted" in Paragraph 5 mean?A.Courageous.B.CowardlyC.EnergeticD.SlowWhich ability is most important for dogs to rescue people trapped in snow?A.Sharp hearingB.Swift movementC.Extraordinary smellingD.A strong memoryWhat is the passage mainly about?A.Selection process of rescue dogsB.Qualities and training of rescue dogs.C.Risks rescue dogs are faced withD.Types of tasks rescue dogs can perform请帮忙给出每个问题的正确答案和分析,谢谢!

考题 Passage TwoThe lion may be the most famous of all the predators of Africa, but one of the most fascinating is the wild dog. Wild dogs are fairly small, averaging seventy pounds, with round, fanlike ears that look too big for their heads. They have shaggy brown coats with scattered patches of white. One of these animals by itself looks harmless or even comical. But when they band together, in packs of up to forty, the wild dogs become dangerous predators that tirelessly run down and kill animals that are many times their own size.Wild dogs have to be good hunters in order to feed their large families; a single female can have as many as sixteen pups at a time. But usually only one female in a pack breeds at a time, and all the pack members help to care for the young. At first, the pups feed on their mother's milk. Then the other dogs begin to bring back meat from the kill, carrying it in their stomachs and throwing it up when the pups come running to them to beg for food. Finally, the young dogs begin to go along on hunts. At this time one of the most striking differences between wild dogs and lions can be seen. When a pride of lions makes a kill, the adult males always eat their fill first. But the wild dogs let the pups feed first, even when they are still too young to really help in making the kill.36. A good title for this passage would be ______.A. Africa's Wild DogsB. Killers of the PlainsC. Predators of AfricaD. The Greedy Lion

考题 请阅读短文,完成第小题。 Photographer Teresa Berg replaces a Rottweiler's collar with a pink scarf. She picks a string of pearls to complement a dachshund's coat. She is taking glamour shots of shelter dogs, hoping her spiffed-up subjects will be adopted more quickly."Most photos show dogs in cages, looking dirty, and mangy," says Berg. "I consider my work like an antismoking campaign. We have to make adopting cool." Her father wouldn't allow her a dog of her own as a kid. He did, however, show her how to use a camera. Together, they took pictures and developed them at his office. Living in Dallas at 24, Berg found her perfect roommate on the street: a Border collie-Shetland sheepdog mix she named Gpsy. Berg always has a soft spot for the ones that don't have anyone to love. For years, she worked as a real estate agent, but she quit in 2006 to launch a photography business. Searching the Internet for a dog to adopt as a companion for Max, her Pomeranian, she was instantly put off by the photos online:"They had dirty laundry, dirty dishes, and empty pizza boxes in the background," she says. Berg finally found Flash, a 12-year old long-haired dachshund who was a Dallas rescue dog. She went to pick him up and ended up volunteering to take pictures of all the rescued dogs there for free. As more dogs went to the program, she took their pictures too. In the following year, after the photos went up on the website of the Dallas-Fort Worth Dachshund Rescue, the group's director noticed that adoptions had doubled compared with last year. She attributed this to the professional photos. "When dogs are adopted that quickly, it makes room for others off the streets, "Berg says. Over the years, Berg has developed some tricks to snap flattering pictures: position dogs so that light falls on their faces, and shoot at eye level. In 2011, hoping to inspire more photographers, Berg posted video seminars on focusonrescue.com. About 75 people per month now watch her offer tips for taking quality pet photos. She's gratified to see the recent wave of well-shot dog photography on shelter websites and social-media sites. In the past couple of years, Berg has added two dogs to the Dallas home she shares with Flash and her husband: a dachshund named Jasper and a Pomeranian named Maggie:"I want to take all the shelter dogs home; that's the hard part," Berg says."I have a particular affinity for dogs with gray muzzles." Why did Berg, the photographer, put scarf and pearls on shelter dogs? 查看材料 A.Because she enjoyed taking fancy pictures of dogs. B.Because she was a faithful antismoking campaigner. C.Because she wanted to make their adoption quick and enjoyable. D.Because she felt relieved to make them look attractive and stylish.

考题 Of all Barry H.Landau's anecdotes about his friendships with presidential dogs,perhaps the best is the one about the time the Clinton White House called to postpone his play-date with Buddy. Yes,Landau is both human and an adult,a 60-year-old author,presidential historian,former White House protocol officer and memorabilia collector.But so enamored is he of dogs,and so well connected to a succession of presidents,that he had an appointment for a South Lawn romp one day with Buddy,Bill Clinton's Labrador retriever(拉布拉多犬). Logistics got in the way,though,and hence Clinton secretary Betty Currie's apologetic voice mail left at the Smithsonian Institution,where Landau was doing research:"I'm sorry,but we'll have to reschedule Mr.Landau's play-date with Buddy." Not surprisingly,this is a happy week for Landau,with the new Obama family dog,Bo,joining a White House tradition that dates to George Washington.It's one that Landau feels is invaluable to a presidency. "Having a dog just humanizes a president,"he says."It completes the picture.It's something people can relate to." And Landau has related to the best of them.He's known about 25 White House dogs since the Eisenhower administration.Among the presidential-pooch memorabilia in his Manhattan apartment are matching orange inaugural dog coats worn by LBJ's twin beagles(小猎犬),Him and Her,and a photo of Landau kissing Clipper,JFK's German shepherd. Where does Landau live?A.Washington,DC B.Manhattan,New York City C.Baltimore,Maryland D.White House

Logistics got in the way,though,and hence Clinton secretary Betty Currie's apologetic voice mail left at the Smithsonian Institution,where Landau was doing research:"I'm sorry,but we'll have to reschedule Mr.Landau's play-date with Buddy." Not surprisingly,this is a happy week for Landau,with the new Obama family dog,Bo,joining a White House tradition that dates to George Washington.It's one that Landau feels is invaluable to a presidency. "Having a dog just humanizes a president,"he says."It completes the picture.It's something people can relate to." And Landau has related to the best of them.He's known about 25 White House dogs since the Eisenhower administration.Among the presidential-pooch memorabilia in his Manhattan apartment are matching orange inaugural dog coats worn by LBJ's twin beagles(小猎犬),Him and Her,and a photo of Landau kissing Clipper,JFK's German shepherd. Who was the first president to have a dog in the White House?A.Bill Clinton B.John Kennedy C.Dwight Eisenhower D.George Washington

考题 We all love a hero,and rescue dogs are some of the biggest heroes of all.You will often find?them going above and beyond duty to save someone,risking—and at times losing—their lives in the?process. Rescue dogs are generally found in the Sporting and Hunting Groups,or from the traditional?Herding Group.These types include the Bloodhound,Labrador Retriever,Newfoundland,German?Shepherd,Golden Retriever,and Belgian Malinois—all of which are chosen for search-and-rescue?duty because of their amazing physical strength,loyalty,and their tendency for mental stability. These types also have a keen sense of hearing and smell—to better locate lost individuals—and?are often able to access hard-to-reach areas.As highly trained animals,they serve in many different?fields,including specialist search,snow slide rescue,dead body location,and tracking. To overcome obstacles and succeed when performing the demanding duties of a search-and-rescue?worker,a dog must display certain qualities.In addition to intelligence and strength,the dog must be?swift,confident,easily trainable,adaptable,and have a high level of stamina(耐力)and endurance.A strong sense of group cooperation and an ability to engage in friendly play during“down”time is also required of search-and-rescue dogs. A rescue dog goes through many,many hours of intensive training to be fit for duty.Training is not for the faint-hearted.Certification training can take from two to three years,working three to four hours a day,three to six days a week,often in group,team-oriented sessions. Each search-and-rescue field requires different types of training.Rescue training,for instance,includes“air scenting”—where dogs are trained to smell the air for the victim′s scent(气味)and then follow the scent to the person.This ability is crucial to finding victims trapped under collapsed buildings and snow slide. Rescue dogs are chosen probably because.A.they are loyal B.they are brave C.they have amazing appearances D.they have good eyesight

考题 共用题干 Study Says Dogs Can Smell CancerDogs are known for their sense of smell. They can find missing people and things like bombs and illegal drugs .Now a study suggests that the animal known as man's best friend can even find bladder(膀胧)cancer.Cancer cells are thought to produce chemicals with unusual odors(气味).Researchers think dogs have the ability to smell these odors,even in very small amounts,in urine(尿).The sense of smell in dogs is thousands of times better than in humans.The study follows reports of cases where,for example,a dog showed great interest in a growth on the leg of its owner. The mole(痣)was later found to be skin cancer.Carolyn Willis led a team of researchers at Amersham Hospital in England.They trained different kinds of dogs for the experiment. The study involved urine collected from bladder cancer patie nts,from people with other diseases and from healthy people.Each dog was tested eight times.In each test there were seven samples for the dogs to smell.The dog was supposed to signal the one from a bladder cancer patient by lying down next to it.Two cocker spaniels(短腿长毛垂耳小猎犬)were correct fifty-six percent of the time. But the scientists reported an average success rate of forty-one percent.As a group,the study found that the dogs chose the correct sample twenty-two out of fifty-four times .That is almost three times more often than would be expected by chance alone.The British Medical Journal published the research .In all,thirty-six bladder cancer patients and one hundred and eight other people took part.During training,all the dogs reportedly even identified a cancer in a person who had testedhealthy before the study.Doctors found a growth on the person's right kidney(肾).Bladder cancer is the ninth most common cancer worldwide.The International Agency for Research on Cancer says this disease kills more than one hundred thousand people each year. Doctors say cigarette smoking is the leading cause of bladder cancer.The person who had tested healthy before the study______.A: dropped outB: passed awayC: was found to have cancerD: was found to remain healthy

考题 单选题Adam’s dog, a golden retriever named Hans, can respond to over 150 different commands. Adam cites this fact as evidence for his claim that Hans can understand the English language.  Which of the following, if true, casts the most doubt on Adam’s claim that Hans can understand the English language?A Each of the 150 commands to which Hans responds involves both a spoken word in English and a distinctive hand sign.B Hans does not respond to the same commands when spoken to him by Adam’s French and Italian friends in their own languages.C Scientists have demonstrated conclusively that canine vocal chords are incapable of replicating many of the sounds used in the English language.D Animal behaviorists have demonstrated that even very young dogs surpass both wolves and chimpanzees—animals that are thought to be more intelligent than dogs—in the ability to understand human nonverbal communication.E The golden retriever is widely considered to be less intelligent than the border collie, and no border collie has ever been shown to truly understand the English language.
