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！

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
