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 (氣味) and then follow the scent to the person. This ability is crucial to finding victims trapped under collapsed buildings and snow slide.

　　40.【答案】A.

　　【考情點(diǎn)撥】事實(shí)細(xì)節(jié)題。

　　41.【答案】B

　　【考情點(diǎn)撥】詞義理解題。

　　【應(yīng)試指導(dǎo)】第五段主要描述搜救犬需要經(jīng)過長期的艱苦訓(xùn)練，所以這種訓(xùn)練應(yīng)該不適合懦弱膽小者，只有頑強(qiáng)的搜救犬才能堅持下來。由此推測。faint—hearted應(yīng)指“懦弱的”，故選B。

　　42.【答案】C

　　【考情點(diǎn)撥】推理判斷題。

　　【應(yīng)試指導(dǎo)】由第六段最后兩句可知，搜救訓(xùn)練的一項(xiàng)內(nèi)容是讓搜救犬去嗅空氣中受害者的氣味，這項(xiàng)能力對發(fā)現(xiàn)被困在坍塌建筑物和雪崩中的受害者至關(guān)重要。由此可推斷，在搜救被困在雪里的受害者時，搜救犬極其敏銳的嗅覺是最重要的，故選C。

　　43.【答案】B

　　【考情點(diǎn)撥】主旨大意題。

　　【應(yīng)試指導(dǎo)】文章第二、三、四段主要講搜救犬需要具備的能力和條件，第五、六段講搜救犬的訓(xùn)練.所以這篇文章的主題是搜救犬的本領(lǐng)和訓(xùn)練，故選B。
