问题 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 Groups. 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.
What is the passage mainly about?
选项 A、Selection process of rescue dogs.
B、Risks rescue dogs are faced with.
C、Qualities and training of rescue dogs.
D、Types of tasks rescue dogs can perform.
答案C
解析 选项A搜救犬的挑选过程，文中并未提及。文中只说在何地选择何种狗做搜救犬。选项B搜救犬面对的风险，文中并未做具体说明，只是在第一段引入话题时简单陈述了一下，并不是全文的主要内容。全文用多个段落说明了搜救犬应具备的素质及受训的艰苦。所以选项C正确。选项D搜救犬可执行的任务类型，文中提及任务类型作为例子，目的是举例说明搜救犬接受的不同训练，不是文章主题。
