问题    Authorities agree that the dog was the first of man’s domesticated animals. How and when this domestication took place, however, remains unknown. A 50,000-year-old cave painting in Europe seems to show a doglike animal hunting with men. But most experts believe the dog was domesticated only within the last 15,000 years. Moreover, fossil remains that would substantiate the presence of dogs with humans have not yet been unearthed for periods earlier than about 10,000 BC.
   One theory holds that humans took wolf pups back to their camp or cave, reared them, allowed the tame wolves to hunt with them, and later accepted pups of the tame wolves into the family circle. Another theory suggests that dogs were attracted to food scraps dumped as waste near human living sites. As they ate them up and kept the site clean, the dogs offered a service to the humans. In turn, the humans would accept the presence of the dogs and would not drive them away.
选项
答案     权威部门认为，狗是第一种被人类驯养的动物。然而，如何以及何时开始驯养一直不为人知。在欧洲5万年前的洞穴壁画上似乎显示有类似狗的动物和人们一起狩猎。但专家们大多认为，狗的驯养只是在1．5万年前才开始的。另外，迄今为止尚未发现早于约公元前1万年的能证实狗和人在一起的化石。
    有一种理论认为，人把狼崽带回他们的营地或洞穴饲养，并带着驯化的狼一起狩猎，以后就接纳驯化的狼崽进入了人类的家庭圈子。还有一种理论认为，狗被人类住地附近倾倒的残羹剩饭所吸引。由于狗能清除那些垃圾，保持住地干净，从而给人们提供了服务。因此，人们就接纳了这些狗，不愿把它们赶走。
